Hi Everyone,

I accidentally hit the OTA update (software ver. 1.22.651.3 710RD) for my rooted HTC EVO 4G LTE phone (whoops!). I have SuperSU Pro with Survival Mode activated but that didn't work. I never installed special ROMs and primarily used ROOT for Tethering.

At any rate, my root is now gone and I can't find any discussions about how to re-root after an OTA update. I don't want to screw up my phone any further since it seems to be working ok otherwise.

Any suggestions?

Thanks!

You'll have to do the HTCDev unlock method (easiest way is through RegawMod). That's the only way right now.

actually the best way is htc dev using the adb tools mini sdk, regawmod has not been fixed and there are a lot of users complaining that they get stuck. To me it only takes a little common sense to solve 90% of the issues using regawmod but some people need their hands held and that thread is slowly boiling down to the worlds most repetitive support desk.


HTC Dev Unlock

Requirements
HTC Drivers
ADB Tools Mini SDK

Setup
  1. Install HTC Drivers if necessary
  2. Extract ADB Tools anywhere, doesnt matter
  3. Open ADB Tools and hold shift+right click, select open command window here
  4. In phone settings, enable usb debugging and disable fasboot
  5. Connect the phone to pc

Steps
  1. In the command window type adb start-server
  2. Next type adb reboot bootloader
  3. Select fastboot
  4. Type fastboot devices to make sure you are connected
  5. Type fastboot oem get_identifier_token
  6. Right click and select mark, click and drag from the top arrows to the bottom arrows and make sure not to highlight any empty spaces as this will confuse the website, right click and it will be saved to clipboard
  7. Now go to HTC Dev and if you don't already have an account, sign up for it
  8. Go to unlock bootloader and select other supported models and accept the agreements
  9. Skip the steps until you get the to token submit window and paste the token you copied earlier and submit.
  10. Go to your email and download the unlock_bin code
  11. Put the code in the ADB Tools folder
  12. Type fastboot flash unlocktoken Unlock_code.bin
  13. When the phone prompt comes up to unlock bootloader hit yes, now you are unlocked, re-enable usb debugging and disable fastboot
  14. Type adb reboot bootloader
  15. Type fastboot devices to make sure phone connected
  16. Type fastboot flash recovery openrecovery-twrp-2.2.2.0-jewel.img
  17. Type erase cache
Reboot phone and you will have unlock and recovery, all thats missing is to restart phone in bootloader and select recovery to flash a rom. Wipe Dalvik, cache, Factory reset, system and then install the rom. If it doesn't boot, extract the boot.img from the rom and put it in the adb folder and in fastboot type fastboot flash boot boot.img and reboot

Hmm. Thanks for the help. However I was not aware that rooting the phone and doing this process would completely reset the phone back to stock. Now I have to set everything up again. Is this normal?

Well, after getting the phone going and attempting to use programs with root privileges, it seems that the rooting process didnt work. All the steps went just fine until I got to the last one and it said to "wipe cashe" when I typed that in it didnt work, so I just skipped that step and rebooted the phone.

Is that what caused the root to not take to the phone?

What steps did you do? I did RegawMOD last week and it was done in like 5 minutes.

Do THIS, and get back to me.

Also tried this last night. I plug my phone in, hit the ROOT button and nothing happens. I actually get a "not responding" on the software. My phone does not reboot into recovery. Does the HBOOT version matter with this? I am v1.19

Sorry, I am still learning all these terms. Not exactly sure what effects what.

I rooted and put Cyanogenmod on my OG EVO and never had this much trouble.

FYI: I was rooted before doing the latest OTA update. So I still have a Super user icon but if I click it it cant update the binary (because I am no longer rooted)...I read somewhere that people said to do a factory reset then try this rooting method again, because of old junk files left behind on the phone. This true?

If I want to completely update my phone (Android 4.0.3, Soft ver 1.22.651, baseband 1.02 because I pretty much got the phone the phone in December and immediately rooted it), will this method work? I'd really like to get Mean Rom but obviously, I'm in need of a few updates and I'm trying to figure out the simplest way to get there. It seems like doing all the official updates and then re-rooting and then installing MR would be the simplest way to do it buuuuut better to ask and be wrong and pointed in the right direction than screw everything up.

Why don't you try getting S-off, then updating everything without having to unroot & root again?

    If that makes it easier, then okay. I'll get S-off. I just wasn't sure and the update requirements for Mean Rom are hefty for me. Thanks.

    Read the guide in the link below. You'll understand why S-off is the way to go.

    Yes, it takes a few minutes of your time, but it's worth the trouble to do it and get it done, particularly given some of the restrictions HTC has put in place on the newer bootloaders (even after unlocking the bootloader there are still restrictions).
