Reason for this guide:

I have tried to go back to RUU and doing this with the RUU applications didn't work, the installation always failed. Because of that I was a bit afraid never to be able to get back to stock / RUU again

steps I did - i'm not sure if step 2 and 3 are necessary, but for me it worked like this

!!!DO NOT RELOCK the bootloader before Step 4 - this will brick your phone!!!

1. download RUU for your device here (check your radio at top the bootloader menu)

2. extract the RUU rom from RUU application
start the ruu application, even if it fails. also start the flashing process, nothing will happen here. search for the ruu logs, for me at c:\ruu_log. in the log (for me in line 191) is the path to the rom.zip that should get flashed. something in temp folder... for me the line looks like this:
"<T093343><DEBUG><CMD>fastboot -s HT1BMVMXYZ flash zip C:\users\raangu\AppData\Local\Temp\{1235}\{12345}\ rom.zip</CMD></DEBUG></T093343>"

3. flash the needed images
in the rom.zip you will find a boot_signed.img, a system.img and a recovery_signed.img. flash all these images with fastboot.

In command line:
fastboot flash system system.img
fastboot flash boot boot_signed.img
fastboot flash recovery recovery_signed.img

4. relock the bootloader
In command line:
fastboot oem lock

5. install with RUU application
now run the RUU application again and follow the instructions.


You are back on RUU now!

Hi agv983,

with "flash all these images with fastboot" I mean the lines below:

fastboot flash system system.img
fastboot flash boot boot_signed.img
fastboot flash recovery recovery_signed.img

so you dont flash these things with cwm or something else. you do it with fastboot in command line.

did you take a look in the ruu_log? the path is written there.

Hi PaXGeN,

I'm not sure if this changes your Device ID

Maybe only for sensation?

Hi mmtrt,

I can't tell if it bricks your phone, but there are several RUUs for different Radio versions available. thought for each Radio there is also a RUU...
