[X920d] How to Unroot HTC Butterfly

acid28 · Mar 3, 2013

This tutorial is made for those people who want to unroot and revert there HTC butterfly to stock firmware by flashing Stock RUU using ADB commands
1. download the stock RUU in this link. This is a working Stock RUU image and can be flash only using ADB command. the zip file will prompt you that it is corrupted when you try to open manually. rename the file to PL99IMG.zip to flash it faster.

PL99IMG_DLXB1_U_JB_45_hTC_Asia_WWE_1.12.707.1_R_Ra dio_3A.22.306.10_10.07.1060.04D_release_signed.zip

2. You will need sdk & and drivers, please take a look here. if you already have it, continue. extract the folder and copy the PL99IMG.zip to that directory.
3. Reboot to bootloader by Holding Vol down + Power button
4. Connect your phone to the PC while in the bootloader. The phone should say fastboot USB, if not, select fastboot on the phone & check if it says fastboot USB, if not, change the USB port you are using.
5. open a command prompt and browse to the folder containing the ADB files.
6. enter the following commands

fastboot erase cache

7. You may not see any output, then enter the command

fastboot oem rebootRUU

8. You phone will now go into the RUU mode.
9. Wait for around 30 seconds, then enter the command

fastboot flash zip PL99IMG.zip

if this error will prompt you. enter the command again in step 9.

FAILED (remote: 90 hboot pre-update! please flush image again immediately)
Normal after Hboot version changes. You need to run only the flash command again (not the whole set of commands, just the fastboot flash command.)

10. The installation will begin and you will be able to see the progress at every step.
Once done, enter the command

fastboot reboot

Unroot will remove "This build is for development purpose only" warning msg? And show locked in hboot?

No. It will show relocked. Unless we get S-off there is no changing this dev unlock flag.

Can you enter bootloader and use fastboot commands?
If you can , use this fastboot command in cmd window "fastboot getvar all" and paste here all stuff you get on that screen.

Got it fixed by unlocking the bootloader and flashing a different RUU.

This is what i did that caused problems.
unrooted with supersu.
locked bootloader from fastboot
rebooted to fastboot
flashed this zip file. -> unable to flash
flashed stock recovery - ok
flashed zip file - unable to flash.
reboot phone - stuck in bootloop.
flashed boot.img - ok
tried flashing zip again - problem
fixed it by
went to htc and unlocked bootloader.
flashed twrp.
flashed a different .img from TW region.
back to life.

my guess is something about this zip file that's not working as it's supposed to.
