Default Quick INTRO TO ROOTING for those new to rooting

Heard about rooting? Have no idea where to even start? This thread is a starting point for YOUR education in how to take control of your phone!

Benefits of rooting:


*Removing bloatware placed on the phone by Sprint (Peep, SprintZone, Sprint NASCAR, etc)
*Overclocking: this will let you use your phone at faster than the 998mhz speeds by default
*Underclocking: huge battery saver because it will throttle your phones processor down when its not in use
*Loading custom bootscreens while the phone is powering up
*Flash ROMs that will let you do a variety of different things. An example is the Cyanogen ROM will let you hook up a bluetooth mouse to your phone to interact with the phone that way.
*Flash Kernels that will increase performance. These are the ROMs that will do things like break the HTC-set 30 FPS (frames per second) cap in addition to allowing over/underclocking.
*Use a variety of apps that require root to work. An example is 'ShootMe', which lets you take screenshots of your phones screen. Another is 'Titanium Backup', which can back up all your apps+data (even protected apps). Yet another is 'CacheMate', which will clear your phones cache to improve performance.
*Create full system image backups (nandroids)
*Need more convincing? Here are some apps only available to root users. (credit to earlymon for the link!)

A few common courtesies/norms exist for this. Rooting requires READING! READ READ READ up on everything you can get your hands on as much as you can! Read the 100 page threads, watch the videos, all of it! People here are more than willing to help but its tacky to ask a question thats already been asked on the first page of this forum! Use the search function, do your due diligence to find an answer, and if you turn up nothing on here or the EVO Development forum on XDA (where the people who make all this possible reside), only then ask. You are big boy (or girl), and hacking your phone is a grown-up task so act accordingly!

What this thread DOESN'T do is explain particular methods of rooting or flashing particular ROMs. This is merely a primer to get you up to speed on the terminology and basics so it doesn't look like quantum physics gobbledygoop that melts your brain.

No matter what method you use, read through it fully till you know it by heart and follow the directions EXACTLY!

1) Rooting gives you superuser access to your phone. Think about your computer at work: the IT guys are in control of it and can limit your actions to what programs can be on it and what you can modify. They can do anything from disable copy/paste to censoring websites. Now, you are in control. Rooting can be done in a variety of ways, I used the SimpleRoot method, a lot of others here use unrevoked.

2) Rooting lets you 'flash' things to the phone. "Flashing" means either replacing or adding to the current operating system:

ROM: Read Only Memory - The ROM is the firmware/software on your phone which act like the operating system (OS) for your phone. Popular ones are BakedSnack, Fresh and Cyanogen. think of ROMs as different 'flavors'. Each has their own pros and cons. Large file (usually over 150 megs)

Radios: is referred to the phone radio portion, for the EVO it is CDMA (Code division multiple access). The Radio is essentially a ROM that controls the phone function part (as oppose to PDA function part) of your phone. In the field of Radio ROM upgrading, may have effect on your phone reception quality, battery life (optimized phone function), signal strength, etc. Small file (usually under 10 megs)

Kernels: is the central component of most computer operating systems; it is a bridge between applications and the actual data processing done at the hardware level. Small file (usually under 10 megs)

RUU: a ROM that will bring your phone back to unrooted, stock condition. As rooting voids your warranty, this is a great ability to get back to out-of-the-box condition. Large file (usually over 150 megs).

Apps: some applications can be flashed to the phone to make them part of the system so they cannot be removed. An example of why you might do this is the 'Mobile Defense' app. It is a phone locating software using GPS, so when this is flashed it will make itself invisible and a thief/etc would not be able to uninstall it. Small file (usually under 10 megs)

bricking: When things go terribly, terribly wrong and your phone becomes a paperweight. This is always possible though if you take the time to read and follow directions EXACTLY can be minimized.

adb: Android Debugging Bridge. Certain things like installing a custom bootscreen require use of ADB to accomplish. Once you download it to your PC, you open a command prompt (for PCs go to Start and enter 'cmd' in the 'run' prompt), then change the directory using DOS commands to the folder ADB is saved in. For simplicities sake, I saved mine to "SDK" on the root of my C: drive. Then I type "cd c:\sdk" to get to the folder I can run the ADB from.

bootloader: A small program that loads the operating system into the computer??s memory when the system is booted and also starts the operating system. The ideal one for the EVO is the 0.76 bootloader, referred to as the 'engineering bootloader', which lets you utilize fastboot commands.

fastboot: This is something you can do when your phone is rebooted into the bootloader while its plugged into your computer via USB, open a command prompt on your PC then execute commands (ive only ever done it to replace my splash screen). Fastboot is protocol used to update the flash filesystem in Android devices from a host over USB. It allows flashing of unsigned partition images

Deodex & Odex: A ROM can have either, a deodex ROM is more customizable than an odex one to allow theming. Themes are customized appearances for things like the notification bar.

3) You flash things by placing the zip into the main directory of your sd card. Then you reboot the phone into whats known as 'recovery', which is like hitting F3 (or whatever your computer requires) while its booting up to get access to system info or boot into safe mode, etc. There are multiple ways to reboot into recovery. The main way is to hold the volume button down, then power up. Programs like ROM Manager and Fresh Updater let you reboot into recovery from your phone while its powered on. Recovery will give you multiple options, like flashing from a zip, creating/restoring a nandroid, etc.

4) Rooting lets you create nandroid backups. These are full system image backups like your computer can make, which let you restore fully to the point where you made it. The first thing you do after rooting is make a nandroid, so you can always go back to ground zero. Its always a good idea to make a nandroid before flashing anything in case something should go wrong. With nandroids, you can go back and forth between any ROM you wish with ease. Also a good idea is to copy the nandroids from your SD card to your computer just in case.

5) Flashing a new full ROM (ie. cyanogen) requires a complete wipe of your phone! (usually factory reset, data, cache and dalvik cache). Since a nandroid backup requires root access, you will have to backup your phone piecemeal to get things back the way you want it once you root and flash a new ROM. Flashing radios/kernels/apps by and large do not require wipes. Backing up usually requires a tandem of apps that can be found in the market. I personally use:

MyBackup Pro: Allows you to backup apps and data (SMS, MMS, call log, system settings, android home, dictionary, etc) to your sdcard or their online server.
Astro File Manager: Lets you backup apps to your sd card. I use both for apps for sake of redundancy should something screwy happen.

For more redundancy on what apps you have, try out the AppBrain Market app and website. Install the app and enter your gmail into it, and choose to 'sync with appbrain'. This will make a list show up on the website you can view on your computer of currently installed apps, which is useful since you aren't going to be able to make backups of protected apps. Be sure to move the list of your apps to a separate list (not default one) so you don't lose it when it resyncs after you root/flash and log in.

An example of how one might proceed with backing up and restoring:

Quote:
*Back up your gmail contacts that are stored in the cloud
*Log into gmail on your PC.
*Select Contacts
*Click the 'More Actions' dropdown bar and select export
*Select the preferred format (which means the google csv format or the outlook/vcard format for your preference)
*It will download to your PC as 'google.csv', you can open it in excel if you wish. Throw it in your backup drive or directory or phone's SD card for safekeeping
*Optional: rename it with a date so you know when this backup was made, I use a date format like 082810Contacts.csv
then...

Quote:
*Use Astro to save all your apps
*Use MyBackup Pro to save other data (SMS, MMS, bookmarks, dictionary, moreiconswidget, system settings, android home). Do NOT use it to backup your contacts/calendar, those are saved up in the cloud safely in gmail, if you try to restore those then you might get duplicate entries for everything. Take notice that if you save contacts as 'phone' contacts and not 'google' contacts, they will not be uploaded to the cloud and therefore you should most certainly back them up. (thx shadow006
*Root & Flash a ROM: once again, this thread is not for explaining that.
*Enter your gmail info into the phone so you can access the market and re-download Astro and MyBackup Pro.
*Reinstall apps (this is the tedious part that takes forever since you have to do them 1 by 1, and you will contemplate suicide)
*Menu->Scenes->Clean Slate. In my experience, if you don't do this then when you try and restore 'home' with mybackup you will get big errors. One time I had a widget that took up parts of 2 homescreens and attempting to remove it would force-close (FC) the phone.
*Use MyBackup Pro to restore data. (NOT CONTACTS OR CALENDAR! UNLESS CONTACTS ARE 'PHONE' CONTACTS, NOT 'GOOGLE' CONTACTS, THEY WILL AUTOMATICALLY RESTORE)
*MyBackup prompts restart, do so, when it reboots you should see your homescreens more or less like they were.
READ READ READ! Have fun, and set aside an entire, full evening before you root! It is possible to go through the complete process of rooting/flashing in less than 20 minutes but something almost always goes wrong. Be patient, and you will prevail having learned a ton and having a badass, unrestrained beast of a phone.

Thanks for this. I just got an EVO yesterday and my wife got a Hero today. Looking to get rid of bloatware, but have a lot of questions that need researching.

rooting the Hero for your wife's phone is fortunately an extremely easy task compared to the EVO since its been out far longer. FreshKitchen for hero by flipz (who does Fresh for EVO as well) has a program that auto-roots it, which is what I used: Hero CDMA Geek For Me – Sprint Evo 4g & CDMA Hero.

Flipz is making a FreshKitchen for the EVO now and the beta should be released soon, though!

If anyone has ideas on what might be added to this thread as far as bare basics on terminology and such, post them and I could add them.

OP updated with benefits of rooting

Very useful write up, thanks! This should be a sticky, I was looking at the top and didn't see anything like this. Don't know if I am ready to root yet, my first WM phone I waited for quite a while.

Mods/Admins, this would be a great sticky! The definitions alone are so helpful to us new folks who get on here and try to shuffle through this "flash a ROM" stuff when all we think we want is wireless tether.

Thanks, OP!

Thanks Cabbie!!! I've been with my EVO now for about 6 weeks and I think I'm about to propose to it... LOL my girlfriend hates how much time I spend with my EVO!

I've been on this forum since I got my EVO and I've been slowly learning this stuff the hard way, you just made this very easy.

I'm having a Sprint technician root my EVO (off the clock obviously) tonight at 6 pm! I can't wait! I'm too chickenshit to do it myself...

thats really cool that you know a sprint tech who knows wtf they are doing everyone i talk to is really clueless about the phone, but part of that i think its because they aren't allowed to buy the evo till some date after the release so the customers get it first.

is there anything i could add to the OP that would be helpful?

How did the root go last night? Did you watch what he did? Any pointers you can give us noobs? Thanks.

Considering this is a noob thread, and I've read all I can understand about this, I have a few questions. i posted this in another thread a few days ago but have not gotten any answers. All I want to do is to get wifi tether, use setcpu, and maybe get froyo running. I have a few questions though:

1. Is this a "full root"? I've been reading, and some people say this isnt a full root, meaning there's no way to get froyo running on it.

2. I would like to get rid of the stock crap apps. From what I gather, the only way to do that is to completely wipe all apps, and start over one by one?

3. I understand you can get a ROM manager, does this allow you to switch between roms or what?

4. This can be completely undone right? I've had problems with 2 evo's, i just now got a working new evo. But if i have a problem, i can take this off correct?

5. If I don't install froyo with the root, and want to wait til its officially released from sprint, will I have any problems installing it then?

This is a great overview, and I like how it gets into the definitions of various elements involved in rooting.

One problem I have found with many "posts for noobs" is that they are just tutorials, which I'm sure is fine for most people, but the geek in me wants to know what's going on.

I have rooted and unrooted two Evos now and installed multiple roms and troubleshooted my own problems a hell of a lot, and so I don't consider myself a noob anymore, but I still have questions about the nitty gritty of what's actually happening with my phone. If anybody can provide any answers or point me in the right direction to a post that answers these questions, that would be much appreciated. And I will certainly answer any noob questions to the best of my ability.

1. My biggest question is, why do different parts of the OS have to be rewritten separately? I.e., the data, system, cache, dalvik cache. If a nandroid backup is an image of the ROM, why wouldn't it take care of everything? Are different parts of the system stored in physically separate memory chips?

2. And what about the bootloader? Is that stored separately? It seems that the conceptual starting point for any full rooting is to get the engineering build (version 0.76) installed on the phone as opposed to the stock build (version 0.79), and all the rooting techinques are just ways to do that.

4. How about the radio part of it? Why is that separate?

5. I used the Simple Root method to get full root. Does anybody know how the Bloons game from Ninja Kiwi (a great flash game) exploits the system to gain root access?

Thanks!

It has 4G support. Some custom ROMs do not, like the Froyo one that's floating around right now - it supposedly screws up the 4G and the camera. But it's not the root that does that. I'm rooted on stock ROM and have had no problems with 4G, camera, or anything.

Benefits of rooting:

*Free wireless tether, to avoid the $30 monthly fee.
*Removing bloatware placed on the phone by Sprint (Peep, SprintZone, Sprint NASCAR, etc)
*Overclocking: this will let you use your phone at faster than the 998mhz speeds by default
*Underclocking: huge battery saver because it will throttle your phones processor down when its not in use
*Loading custom bootscreens while the phone is powering up
*Flash ROMs that will let you do a variety of different things. An example is the Cyanogen ROM will let you hook up a bluetooth mouse to your phone to interact with the phone that way.
*Flash Kernels that will increase performance. These are the ROMs that will do things like break the HTC-set 30 FPS (frames per second) cap in addition to allowing over/underclocking.
*Use a variety of apps that require root to work. An example is 'ShootMe', which lets you take screenshots of your phones screen. Another is 'Titanium Backup', which can back up all your apps+data (even protected apps). Yet another is 'CacheMate', which will clear your phones cache to improve performance.
*Create full system image backups (nandroids)

A few common courtesies/norms exist for this. Rooting requires READING! READ READ READ up on everything you can get your hands on as much as you can! Read the 100 page threads, watch the videos, all of it! People here are more than willing to help but its tacky to ask a question thats already been asked on the first page of this forum! Use the search function, do your due diligence to find an answer, and if you turn up nothing on here of the EVO Development forum on XDA (where the people who make all this possible reside), only then ask. You are big boy (or girl), and hacking your phone is a grown-up task so act accordingly!.

What this thread DOESN'T do is explain particular methods of rooting or flashing particular ROMs. This is merely a primer to get you up to speed on the terminology and basics so it doesn't look like quantum physics gobbledygoop that melts your brain.

No matter what method you use, read through it fully till you know it by heart and follow the directions EXACTLY!

1) Rooting gives you superuser access to your phone. Think about your computer at work: the IT guys are in control of it and can limit your actions to what programs can be on it and what you can modify. They can do anything from disable copy/paste to censoring websites. Now, you are in control. Rooting can be done in a variety of ways, I used the SimpleRoot method, a lot of others here use unrevoked.

2) Rooting lets you 'flash' things to the phone. "Flashing" means either replacing or adding to the current operating system:

ROM: Read Only Memory - The ROM is the firmware/software on your phone which act like the operating system (OS) for your phone. Popular ones are BakedSnack, Fresh and Cyanogen. think of ROMs as different 'flavors'. Each has their own pros and cons. Large file (usually over 150 megs)

Radios: is referred to the phone radio portion, for the EVO it is CDMA (Code division multiple access). The Radio is essentially a ROM that controls the phone function part (as oppose to PDA function part) of your phone. In the field of Radio ROM upgrading, may have effect on your phone reception quality, battery life (optimized phone function), signal strength, etc. Small file (usually under 10 megs)

Kernels: is the central component of most computer operating systems; it is a bridge between applications and the actual data processing done at the hardware level. Small file (usually under 10 megs)

RUU: a ROM that will bring your phone back to unrooted, stock condition. As rooting voids your warranty, this is a great ability to get back to out-of-the-box condition. Large file (usually over 150 megs).

Apps: some applications can be flashed to the phone to make them part of the system so they cannot be removed. An example of why you might do this is the 'Mobile Defense' app. It is a phone locating software using GPS, so when this is flashed it will make itself invisible and a thief/etc would not be able to uninstall it. Small file (usually under 10 megs)

bricking: When things go terribly, terribly wrong and your phone becomes a paperweight. This is always possible though if you take the time to read and follow directions EXACTLY can be minimized.

3) You flash things by placing the zip into the main directory of your sd card. Then you reboot the phone into whats known as 'recovery', which is like hitting F3 (or whatever your computer requires) while its booting up to get access to system info or boot into safe mode, etc. There are multiple ways to reboot into recovery. The main way is to hold the volume button down, then power up. Programs like ROM Manager and Fresh Updater let you reboot into recovery from your phone while its powered on. Recovery will give you multiple options, like flashing from a zip, creating/restoring a nandroid, etc.

4) Rooting lets you create nandroid backups. These are full system image backups like your computer can make, which let you restore fully to the point where you made it. The first thing you do after rooting is make a nandroid, so you can always go back to ground zero. Its always a good idea to make a nandroid before flashing anything in case something should go wrong. With nandroids, you can go back and forth between any ROM you wish with ease. Also a good idea is to copy the nandroids from your SD card to your computer just in case.

5) Flashing a new full ROM (ie. cyanogen) requires a complete wipe of your phone! (usually factory reset, data, cache and dalvik cache). Since a nandroid backup requires root access, you will have to backup your phone piecemeal to get things back the way you want it once you root and flash a new ROM. Flashing radios/kernels/apps by and large do not require wipes. Backing up usually requires a tandem of apps that can be found in the market. I personally use:

MyBackup Pro: Allows you to backup apps and data (SMS, MMS, call log, system settings, android home, dictionary, etc) to your sdcard or their online server.
Astro File Manager: Lets you backup apps to your sd card. I use both for apps for sake of redundancy should something screwy happen.

For more redundancy on what apps you have, try out the AppBrain Market app and website. Install the app and enter your gmail into it, and choose to 'sync with appbrain'. This will make a list show up on the website you can view on your computer of currently installed apps, which is useful since you aren't going to be able to make backups of protected apps. Be sure to move the list of your apps to a separate list (not default one) so you don't lose it when it resyncs after you root/flash and log in.

An example of how one might proceed with backing up and restoring:



READ READ READ! Have fun, and set aside an entire, full evening before you root! It is possible to go through the complete process of rooting/flashing in less than 20 minutes but something almost always goes wrong. Be patient, and you will prevail having learned a ton and having a badass, unrestrained beast of a phone.
awesome post! very timely! thanks sent...

You also have the option of using a stock rooted rom - and then you have everything the stock phone has, 4G, all of it - plus the advantage of being able to rip out the bundleware that came with the phone, as well as any social networking apps you don't care about - as well as access cool root-only tools like ShootMe.

You can also get that as a deodexed version, allowing you to further customize things.

Flipz is making a FreshKitchen for the EVO now and the beta should be released soon, though!

If anyone has ideas on what might be added to this thread as far as bare basics on terminology and such, post them and I could add them.

OP updated with benefits of rooting
It's funny because I just got an EVO for myself and the HERO for my wife. The main reason I'm looking into rooting is because of the terrible battery life. But I am very nervous about the process. I'm just learning about all of it. If I do this is there any way to restore to factory settings if the phone does brick? I'm really not a smart cookie when it comes to this stuff so I need some advice and suggestions. Thanks.

assuming you successfully root, you can flash the RUU to bring you back to stock out-of-the-box condition, its in the OP

These are some good questions and I'm disappointed that the post doesn't seem to have been acknowledged at all, much less answered. Anyone?

One problem I have found with many "posts for noobs" is that they are just tutorials, which I'm sure is fine for most people, but the geek in me wants to know what's going on.

I have rooted and unrooted two Evos now and installed multiple roms and troubleshooted my own problems a hell of a lot, and so I don't consider myself a noob anymore, but I still have questions about the nitty gritty of what's actually happening with my phone. If anybody can provide any answers or point me in the right direction to a post that answers these questions, that would be much appreciated. And I will certainly answer any noob questions to the best of my ability.

1. My biggest question is, why do different parts of the OS have to be rewritten separately? I.e., the data, system, cache, dalvik cache. If a nandroid backup is an image of the ROM, why wouldn't it take care of everything? Are different parts of the system stored in physically separate memory chips?

2. And what about the bootloader? Is that stored separately? It seems that the conceptual starting point for any full rooting is to get the engineering build (version 0.76) installed on the phone as opposed to the stock build (version 0.79), and all the rooting techinques are just ways to do that.

4. How about the radio part of it? Why is that separate?

5. I used the Simple Root method to get full root. Does anybody know how the Bloons game from Ninja Kiwi (a great flash game) exploits the system to gain root access?

Thanks!

Once you're rooted, you may be curious about root-only apps. In case it doesn't get stickied, here's a _great_ thread on that -

Evo Root Only Apps.

I'm a noob at Rooting also and from my understandings, I can Root my EVO and still keep my stock ROM. I can aswell use Root only Apps like Titanium Back-up or SetCPU without a problem, right?

All I really want to do is keep my Stock ROM and use Root only Apps to improve my battery life. This is very much possible, no problems?

I also would like to know when a new version/update for the EVO comes about, how will this effect my EVO? Will it brick the phone? Do I need to go back to my stock unrooted RUU?

Yes you can. You can have a phone that is 100% stock except that its rooted. And if you are rooted, never accept OTAs, you will lose root. You need to wait for a developer to incorporate the update into the ROM and then you use that to update.

Those are good questions so I'm going to add this to the original post.

I DONT want this to become a troubleshooting thread for issues specific to their phone...this is a resource thread.

Wait so you said I can keep my phone 100% stock, but still rooted...and then you said not to except OTA's because it will unroot my phone. What exactly would happen, would it completely wipe my phone; ie, Stock?

"rooted stock" and "stock" are two different things. OTA updates are "stock," and they are designed to take the "rooted" out of "rooted stock."

But don't worry. Rooted ROMs disable OTA notifications. So you have to actively download an OTA non-rooted stock rom to kill your root status.

And if it does kill my root status, what exactly would happen? I don't plan on using a new ROM.

Then you will have the update, with no root. And you will have to have an unrooted phone until the developers can find an exploit and get your new stock unrooted version, rooted.

If you choose to root now, the best thing to do would be to stick on your current rooted stock rom when an update comes out again, and wait until the developers get the rooted update on the forums. Then you flash it, which is simple.

Im trying to understand this all myself, if i made any mistakes, please feel free to correct me guys.

absolutely yes. BAD BAD things can happen if you flash ROMs intended for other phones, and im fairly sure that if you try to flash a radio intended for another phone you will absolutely brick the device.

Unfortunately, I couldn't find a samsung intercept subforum on XDA for you. But if ROMs have been developed for it, I'm sure its out on the web somewhere.

So I have a question about the Kernels? I have my Evo root with a stock rom with root access. Now I understand that the kernel is the "bedframe" of the phone while the rom is the "mattress". I also understand that you can use apps like rom manager to change the roms. I am slightly confused on the changing the Kernel. So if I have a kernel that is not optimized for a Rom that I would want to run, how do I go about changing it? Do I have to use the ADB again or is it possible to use the ROM manager to change a Kernel as well as a rom?

Reboot into recovery using ROM Manager and flash it like anything else. All it will do is replace your current kernel.

this is a little vague. What ROM and Kernel are you talking about? I don't imagine huge issues occuring unless you flash a kernel designed for an AOSP ROM like Cyanogen vs one with SenseUI like Fresh. If you want to change a kernel, all you have to do is flash it (always wipe cache and dalvikcache before doing so). Just put it on the root of your SD card and go nuts.

Going to add AOSP to the lexicon now

it was stickied but the Mods wanted to clear clutter and bundle it into the one lone sticky at the top of this forum. I've noticed that since they've done so that the redundant 'what is root' thread questions have increased since this root 'lexicon' wasn't immediately apparent to users. Not my forum tho

^ This is true, and although officially we are trying to limit the amount of stickies in all sections to One, it is up to the discretion of the staff member usually in charge of the sections to determine if a another post would be more beneficial in keeping it stickied or not.

in this case i think having this thread falls under such criteria.
The needs of the many outweigh the needs of the few.

Thread re-stickied.
