Keep in mind that rooting only gives you access to the files on the phone, like admin access on a computer. One BIG benefit is the ability to make a complete backup of your phone...called a Nandroid backup. Rooting in of itself does not fix anything. After rooting you can delete the Sprint "Bloatware" which some find makes a big difference in the way the phone feels. After that, if you want, you can flash a custm rom.

Lots of help here when youneed it. :)

Yes, I knew rooting, in and of itself, would only allow me to do so much without installing a custom ROM. I am still undecided about it as of now.

I have actually been doing quite a bit of research and I have been meaning to ask about Nandroid backups. I wanted to try the easy UnrEVOked method of rooting, but does this give me the ability to do Nandroid backups automatically after I do that or do I have to still go through the process of flashing a recovery image first using the Android SDK and HTC Sync? I want to be able to backup my original stock Android 2.1 image before I do anything major to my Sprint HTC Hero. That way I can return to a safe image if I am unsatisfied with the results. Also, once I use UnrEVOked do I have to keep rooting it over and over or is it permanent? I read something about it not unlocking the bootloader but still allowing the handset to be rooted some how.

I appreciate that you directed me to that thread, but it honestly did not answer my questions. I actually read that thread yesterday before I posted these questions.

Again, I thank you for your help. I was just looking for a few specific answers if anyone knows.

Ok, yes you can use unrevoked but you have to have 2......5 (I forget the number) not .6

Then download rom manager from the market and flash the clockworkmod recovery (make sure it says CDMA Hero). Then 'reboot into recovery' and make a nandroid of your stock 2.1 phone. Reboot phone(it may do it automatically) and then you are good to go with flashing roms. Just make sure you flash a rom for a CDMA Hero, no GSM roms as they will BRICK your phone.

As always wipe everything before flashing a rom, data, cache, davlik cache

Hey, thanks for the information. So, am I to assume that by rooting I am automatically able to perform a Nandroid backup, or do I have to install the Clockwork Mod recovery first? I have read that there seems to be a difference between Clockwork Mod Recovery's Nandroid and the one you might use if you do a full blown, command line based rooting to your handset and I think it is called Amon Ra's recovery, which is the more common one to use after rooting. I also would prefer the method where you reboot into recovery, wipe, and then flash, not flash from the actual operating system environment of Android with something like ROM Manager.

Is Nandroid just a generic term for backing up your current ROM or is it a specific software that is already on your handset after you have rooted? For example, my friend went through the command line based rooting process and when he reboots his Sprint HTC Hero and reboots into recovery it actually says Wipe, and Nandroid backup, etc. Also, if I use the UnrEVOked method, is my Sprint HTC Hero permanently rooted until I use one of the methods to unroot it in the unlikely event I need service from Sprint to fix something? Sorry for all of the questions, I am just really new to this and want to proceed with caution.

First, the reason you would download rom manager is to get Koush's ClockworkMod recovery. But if you are interested in RA, you can flash that recovery in rom manager also. As far as rebooting into recovery, that's what you would do in CM or RA

Nandroid is part of recovery(whatever recovery you use), you boot into recovery to make a nandroid, flash zip files, wipe cache, wipe Davlik cache, factory data reset.... you can do this via rom manager with RA or CM

Yes, if you use unrevoked you are rooted. You can unroot simply by running the RUU from Sprint

I really appreciate your help, andygu3. I still have a few more questions and I hope that is okay. Anyway, I was looking at this other method of rooting that seemed even easier than UnrEVOked. It is called Universal 1-Click root and it is available at the XDA-developers forum.

I found this link: Universal 1-Click root - xda-developers . So basically, my question is when and if I performed this would I get full root? For example, I mean full NAND unlocking so I could flash recovery images anytime. I read that UnrEVOked only gives you a partial root that basically does NOT unlock the NAND forever, but only long enough for you to flash your recovery image and then it is locked again. I saw that there was an option for something called UnrEVOked Forever that sets something to "S-OFF" and I am assuming that means the NAND is unlocked forever or at least until you use the tool to set it back to "S-ON" and so forth. So, I guess what I am getting at is which would be better to use, the Universal 1-Click Root or the UnrEVOked Root? Also, I read something about an HBOOT needing to be a certain version. I am really confused about that. Do you know anything HBOOT?

I think you are confusing yourself with all the information that is out there (which is good, your doing the research) but unrevoked will give you full root as well as the universal 1 click. After doing the apk's, you will have superuser permissions

Which is better, I can't tell you that but if you use one or the other, first download rom manager and flash a recovery image either with RA or CM. Then you are good to go.

Again, if you are worried about bricking your phone, it's damn near impossible! Just don't flash a GSM rom or GSM radio

Make nandroids or if you use rom manager 'backup current rom', these may save you some day;)
