    scotty85 Guides Guide

    this is a device specific-thread to help you unlock,install a recovery,and root your cdma evo 3d. this guide originated for the htc rezound, thus some of the names and references. however, all files and info are specially for the evo 3d.

    first and foremost,htcdev is a PITA. it has limitations if you are a "hardcore" rom flasher/rooter/romer. while it may be fine for the folks that want to be completely stock and have root acces to delete some bloatware,and run root required apps,s-off is better,and worth the extra efforts to achieve,IMO.

    for those of us that want complete freedom to mod our devices,htcdev is still a valuable,and a solid,reliable means of adding root acces for other exploits.

    this thread will remain locked in this forum. please start a new thread with any issues,questions,etc. that you have,we are here to help :)

    and now,on with the info!

    the basic steps will be:
    1)unlock with htcdev
    2)temporarily or permanently flash a recovery
    3)flash root files

    before you start,go ahead and download these files:
    -mini-adb.zip: mini-adb.zip
    -ext 4 recovery for cdma evo 3d: PG86IMG-recovery_ext_4.zip )
    -superuser files: for GB or ICS,use the latest superSU from this thread on xda (the download link is where is says: CWM installable ZIP: CWM-SuperSU-v0.96.zip )
    -go to HTCdev - Unlock Bootloader and register an account



    1)unlock with htcdev
    first thing you need is drivers for adb to see your phone. if you have htc sync installed,you should allready have drivers. if not,you can install htc sync,or install these modified htc drivers from revolutionary

    most guides simply say "follow the directions to unlock with htcdev" but im gonna go thru it with ya :) the mini-adb.zip file is all the files that htcdev is telling you to download and put into a folder,so allready this should be a lil easier ;)

    1)prepair ADB
    -unzip your mini-adb.zip file. this is native funtionality in windows 7. you otherwise may need a utility such as "7-zip" to extract,or unzip it. place the unzipped folder onto the root of your C drive on your PC(sorry, you mac guys will need to develop this for yourself,i dont have a mac). root means the top level,not inside any folders. so just copy and paste,or drag and drop the folder onto C with everything else that is there. you may want to rename it to "mini-adb_devicename" since youll be putting some device specific files in here. (directions from here forward will assume this folder to be named "mini-adb_vigor",as an example)
    -open a command window. on windows 7,click the start bubble in the lower left and type "command" in the search box. xp i believe is similar or the same. doing this should open a small black command window.
    -change to your mini-adb_vigor directory. type the following at the prompt in your cmd window:

    cd c:\mini-adb_vigor

    your command promt should change to "c:mini-adb_vigor>" provided you: 1)unzipped the miniadb zip 2)put the folder on your c drive 3)entered the name of the folder correctly ("mini-adb_vigor" in this case)

    -now make sure usb debugging is checked in settings/apps/development,and plug your phone into your PC with a usb cable
    -make sure your phone is being recognized- type:

    adb devices

    if your drivers are installed correctly,this should return your phones serial number. you should hear the "found device" noises when you plug your phone in. if it starts installing drivers,wait for it to finish before typing the adb devices command.

    2)unlock using htcdev
    -go to HTCdev - Unlock Bootloader and sign in to your account. chose your device from the "select your device bar"(or "other supported devices" if its not listed) and click the green "begin unlock bootloader" button underneath.
    -click yes to procede,then read the warnings before checking the boxes and clicking yes to continue,as they are basically explaining that your warranty is now void,and any repairs that your phone needs that may have been a result of unlocking your bootloader and messing with your phones operating system may no longer be covered under mfgr warranty

    *check your hboot screen. if you allready have an htc compatible hboot, then skip ahead to the next step,you dont need this.if you have a pink **locked** at the top of the hboot screen,then it is compatible with htcdev. if you dont have a compatible hboot,then download the RUU for the new hboot. right click it,and run as administrator. plug in your phone when prompted to. it will ugrade your hboot to the htcdev unlock compatible version.

    -steps 1-4 are describing how to get your phone into bootloader mode and connect it to your PC,wich we have done above. ignore these steps and simply type in your cmd window:

    adb reboot bootloader

    it may take several seconds,but this command should boot your phone into the "fastboot" screen wich is white with a bunch of colored writing. once this happens,make sure your phone is still being seen in fastboot. type:

    fastboot devices

    again,this should return your phones serial number.

    -click the green procede to step 5 bubble.
    -steps 5-7 are telling you how to find the files and utilities inside your mini-adb folder. you have them,so ignore steps 5-7.
    -click the green procede to step 8 bubble.
    -heres where steps are important,steps 8-10 are telling you how to get your unlock token,and send it to htc. its phone specific(so they prolly know your serial number,meid,etc) so no,you cant use your buddys unlock token and not have htc know that youve unlocked your bootloader. ;) copy this line either from below,or from step 8,and paste it into the prompt in your cmd window. you have to right click to paste in cmd,you cannot control/v :

    fastboot oem get_identifier_token

    -after yuo hit enter,you will get a bunch of letters that are your identifier token. not much i can say,other than follow the directions in steps 9 and 10 to copy and submit your identifier token to HTC. make sure you get the characters as shown in the pic,with no extra lines or letters. note that you can also hit the "enter" key on your PC to copy,as well as right clicking.
    -click the green submit button. wait patiently for an email containing your unlock code. (dont worry,it should come pretty fast :p )
    -save the unlock_code.bin that htc sends you directly to your mini-adb folder(if your PC automatically downloads somewhere else,no biggie. just move the unlock code to mini-adb folder)
    -click the link in your email to get the rest of the unlock instructions
    -step 12 is where them magic happens :D copy from below,or from htc dev:

    fastboot flash unlocktoken Unlock_code.bin

    -youll see the purdy screen pictured in step 13. use the vol rocker to chose "yes unlock bootloader" and select it with the power button. your phone will reboot,performaing a factory data reset in the process. your data is gone,sorry :( this boot may take a bit longer than they normally do,dont freak out this is normal

    as you can see,once the adb files are put in one place to download,its not hard to use,and the commands are pretty simple. below is what you will see in your command window,the red are my inputs.

    2)flash a recovery
    if you want to run stock,do not permanently install your recovery. keeping the stock recovery on the phone will ensure that you recieve OTAs without a hitch,wich i know is important to alot of users. YES,the OTA will break root. its no big deal. one good thing about htcdev is that you will always be able to reroot after,simply by following steps 2 and 3 again to launch recovery,flash superser.

    once youve either skipped past all the setup,or have re-set up and are ready to root,chose either of the following options to either permantly or termporarily install a recovery:

    1)temporary recovery:
    -move the recovery image file you downloaded above and place it into the mini-adb folder.
    -put the superuser zip file onto your phones sd card
    -enable usb debugging once again,as above. open a cmd window,if its not still open from unlocking.
    -if you had to re-open a cmd window,dont forget to change back to your mini-adb directory:

    cd c:\mini-adb_vigor

    -make sure youre connected by typing:

    adb devices

    -should return serial number
    -check the md5 of your recovery image:

    md5sums <recoveryname>.img

    **make sure the resulting md5 matches the one that is listed for the image that you downloaded. ** (if no md5 is listed,post in the thread,i can download and compare my md5 to yours.this is not as good as getting an md5 from the one who linked the file,but its better than nothing)

    -boot to bootloader:

    adb reboot bootloader

    -check for connectivity:

    fastboot devices

    -should return serial number
    -temporarily launch your recovery to phone memory:

    fastboot boot <recoveryname>.img

    -youll see a (really fast) green status bar on the top right as your PC sends the recovery to your phone. youll then see the HTC splash screen,then your recovery.

    in your command window you will see(red are my inputs):

    2)permanently install your recovery
    -move the image file you downloaded above and place it into the mini-adb folder.
    -put the superuser zip file onto your phones sd card
    -enable usb debugging once again,as above. open a cmd window,if its not still open from unlocking.
    -if you had to re-open a cmd window,dont forget to change back to your mini-adb directory:

    cd c:\mini-adb_vigor

    -make sure youre connected by typing:

    -should return serial number
    -check the md5 of your recovery image:

    **make sure the resulting md5 matches the one that is listed for the image that you downloaded. ** (if no md5 is listed,post in the thread,i can download and compare my md5 to yours.this is not as good as getting an md5 from the one who linked the file,but its better than nothing)

    -boot to bootloader:

    adb reboot bootloader

    -check for connectivity:

    fastboot devices

    -should return serial number
    -permanently flash your recovery to phones recovery partition:

    fastboot flash recovery <recoveryname>.img

    -youll see a (really fast) green status bar on the top right as your PC sends the recovery to your phone,then a (really,really fast) red bar as it flashes it. amon ra is now permanently on your phone when you need it. be aware that you can no longer accept OTAs,unless you reinstall the stock recovery at some point before the next OTAs are pushed.
    -to get to recovery,push the power button to select hboot. once in hboot wait for the green writing to flash and disapear,then select recovery.

    *note that you can still launch recovery by using the command from scenario 1 above.
    -youll then see the HTC splash screen,then your recovery.

    3)flash superuser root files*
    there is not much to explain with this one. if booted to recovery from above,use the recovery menu on your phone to:
    -make a backup of your stock,unrooted rom. completely optional,but a very good idea,IMO.
    -wipe cache
    -wipe dalvik cache
    -install zip from sd card(chose your superuser file)
    -reboot

    *congratulations,youre rooted :D
    you can now run the juopunut bear tool to achieve s-off: Unlimited.IO

    if youre considering leaving htcdev unlock,read the following post to learn some of the pitfalls.

    s-off is better,and worth whatever extra efforts to achieve if available. more info on this thread:

    scotty85 Guides Guide

    after typing this out more times than i can count,i have decided to make up a thread for it. hopefully this will end some of the confusion about fastboot booting recovery,why its better,and what you have to do if you opt not to take advantage of its benefits.

    if you have not rooted yet, consider using the guide here,as ive tried to eliminate some of the confusion from htcdev's page,and using it will give you some basic knowledge and tools that you will use in happily modding your s-on device. youll also potentially have an understanding of fastboot booting your recovery into phone memory,as it is the same thing as what the guide instructions are for a "temporary recovery".

    http://androidforums.com/evo-3d-all-things-root/636832-scotty58-universal-rooting-guide.html

    most folks that have come from other devices are used to the following sequence of events:
    1)root phone
    2)install a custom recovery(generally clockwork mod,or Amon_Ra)
    3)booting to that recovery to make and restore backups,flash roms,etc. since the root method generally gave access to all the phones different memory partitions,many of wich are modifiable via the custom recovery.

    even worse,are folks who have come from different devices and used an app called "rom manager" to manipulate things from within the booted operating system. i am not a fan of rom manager period,even on phones that it works on.

    unfortunately,the above is a recipe for disaster on any s-on,high end htc device.

    to begin,
    a few words about htcdev
    htcdev is htc's answer to the publics cry for unlocked bootloaders,and the ability to modify and install custom operating systems on their htc devices.

    basically,you send information to htc,and they provide an unlock token that is reusable,but unique to your device. this changes the locked lettering at the top of your hboot screen to unlocked,and gives you access to the /boot,/system,and /recovery partitions only of your phone. it is not s-off by any means,and there are still alot of checks being done by the phone,wich lead to disadvantages. most notably,you cannot change any other partitions. hboot,radios,and splash screens are protected and off limits. you also cannot roll backwards in software build numbers and firmware if you flash a leaked rom and dont like it.

    there are a couple of advantages.

    1)unlike the underground exploits used in the past,htcdev will always work. you dont need to worry about unrooting and not being able to root again. if you need to relock your bootloader and flash factory firmware,you will always be able to re-unlock with your original unlock token.

    this makes it convenient for users that only want root access so that they can run a few root apps(titanium backup,wifi tether) and delete some bloatware. the folks that like to run stock,and recieve OTA updates can easily do so by keeping the STOCK recovery on the phone.

    as long as the stock recovery is in place,you are not in danger of an OTA messing up your phone.

    3vo user: but,wait! wont accepting an OTA break my root?!
    scotty: yes,but thats not a big deal. after the OTA has finished,you can quite easily relaunch your temporary recovery,and re-flash your root files,just as you did when you first rooted. re-rooting is easily accomplished,and therefore nothing to be concerned with.

    2)the other big advantage of an htcdev unlocked s-on bootloader,is that since the bootloader is protecting itself,and the radios,it is nearly impossible to hard-brick(i.e.,unrecoverable) device with software flashes. any damaged to the phones filesystem are almost always fixed by RELOCKING the bootloader,and running an RUU(factory signed software package)

    modding your s-on,unlocked device
    first and foremost,remember this:

    **an htcdev unlocked phone CANNOT write to the /boot partition FROM its /recovery partition.**


    what this means is that,unlike your s-off evo 4g,thunderbolt,inc 1,or just about any other htc device you may have messed with,the rom that you flash from a recovery that is permantly installed on your phone cannot install the boot image. since the boot image houses the kernel, the roms kernel is not being installed along with the rest of the rom.

    this means that if your rom requires a different kernel than what is on your phone,it will not boot. it will hang indefinately at the splash screen.

    there are a couple options to work around this handicap with s-on phones:

    1)use juopunut bear's tool to s-off your phone. :eek: doing this makes your phone and recovery act like you are used to(recovery can[/ write to /boot) but does not come without consequence. see this post for more info: http://androidforums.com/evo-3d-all...ty58-universal-rooting-guide.html#post5113887

    2)flash the kernel manually. it can be done with the command fastboot flash boot or it can be done by placing the boot image inside a PH98IMG file and flashing it in hboot.

    PH98IMG flashing is a PITA on an s-on phone,in my honest opinion. the information on the "android info" text document inside the file must contain the correct info or the phone will not let the file flash. this leads to much aggravation,confusion,and an overall very bad rom flashing experience ;)

    therefore,the better way to flash kernels,IF you want to do it manually,is to use the fastboot flash boot command. more info on that here: http://androidforums.com/rezound-all-things-root/499172-how-manually-flash-roms.html#post3933400

    and now the best for last:
    3) fastboot boot your recovery into phone memory

    this involves,basically,placing your recovery image inside the folder that contains adb and fastboot,booting the phone to fastboot,and the launching recovery into phone memory by entering the command:
    fastboot boot recoveryname.img

    do not confuse this with the fastboot flash command.

    fastboot boot is taking an image,and booting it right up on the phone.

    fastboot flash is permantly installing an image into the phones filesystem.

    *if you use fastboot boot to launch your recovery into phone memory,then recovery CAN write to the boot partition,making rom flashing on your s-on device just like rom flashing on an s-off device.

    i.e.,launching recovery from fastboot lets the rom install the kernel,and requires no seperate kernel flashing. this means that when you are following a rom developers install instructions,you can follow the set for s-off devices.

    why does this work?!

    well,an oversimplified explanation is this:
    -fastboot is part of the bootloader,wich can write to the /boot partition
    -launching recovery from bootloader,makes the recoverys operations work thru the bootloader.
    -hence,launched recovery can write boot image. hooray! :smokingsomb:

    all the above applies to bakcups as well. you canot restore a backup from the permenent recovery if it contains a different kernel. just like flashing a rom. all the above info in this post applies to restoring a rom as well.

    last and not least,
    some more detailed instructions

    if you rooted with my guide,then you have seen this before. its basically the directions to "temporarily flash recovery"

    for those that have rooted via other means,you can modify these directions to fit whatever folder you have adb/fastboot in,or you just use these directions:

    download these files:
    -mini-adb.zip: mini-adb.zip
    -Ext 4 recovery image: PG86IMG-recovery_ext_4.zip

    first thing you need is drivers for adb to see your phone. if you have htc sync installed,you should allready have drivers. if not,you can install htc sync,or install these modified htc drivers from revolutionary (i recomand revolutionary drivers)

    1)prepair ADB
    -unzip your mini-adb.zip file. this is native funtionality in windows 7. you otherwise may need a utility such as "7-zip" to extract,or unzip it. place the unzipped folder onto the root of your C\ drive on your PC(sorry, you mac guys will need to develop this for yourself,i dont have a mac). root means the top level,not inside any folders. so just copy and paste,or drag and drop the folder onto C with everything else that is there. rename it to "mini-adb_shooter" since youll be putting some 3vo(shooter) specific files in here. you actually can call it whatver you want,but directions from here forward will assume this folder to be named "mini-adb_shooter"
    -open a command window. on windows 7,click the start bubble in the lower left and type "command" in the search box. xp i believe is similar or the same. doing this should open a small black command window.
    -change to your mini-adb_vigor directory. type the following at the prompt in your cmd window:

    cd c:\mini-adb_shooter


    2)launch a temporary recovery:
    -move the image file from your downloaded zip file, and place it into the mini-adb_shooter folder.

    -type in your cmd window,or copy/paste the commands that are in bold

    -check the md5 of your recovery image:

    md5sums <recoveryname>.img

    i.e.,if youre using an image named shooter_recovery_ext_4,then your command will be:
    md5sums shooter_recovery_ext_4.img

    **make sure the resulting md5 matches any available listed md5 sums. **
    (for the ext 4 recovery linked,the image md5 will be: aff934a272f6ba66cc19e8e4325506a8 )

    -enable usb debugging on your phone and plug it in,charge only mode.

    -check for connectivity:

    adb devices

    -it should reply with your serial number. if so,then:

    adb reboot bootloader

    -this will boot your phone into "fastboot" wich is a white screen with coloered letters.

    -check for connectivity:

    fastboot devices

    -should return serial number

    -temporarily launch your recovery to phone memory:

    fastboot boot <recoveryname>.img

    again,if youre using an image named as above:
    fastboot boot shooter_recovery_ext_4.img

    -youll see a (really fast) green status bar on the top right as your PC sends the recovery to your phone. youll then see the HTC splash screen,then your recovery.

    now that youre recovery is running,you have lots of options. you can mount usb storage to move things on and off the sd card if you need to. you can also flash the main version tool if you need to: main version tool.

    note that once recovery is running,you can unplug from the PC if you want to flash your rom from the couch,ktichen table,or wherever :)

    you can now restore a backup,or flash a rom.

    last and not least,a couple notes:
    -to paste into the cmd window,you must right click/paste. you cannot control/v
    -to copy from the cmd window,right click. click mark. highlight everything to copy in white. now hit enter,or right click again.

    holler if you have more questions :)
