Worked for me as well! I was also on 33R.

Was a scary road to ride but the steps all worked and I am now back to 33R with root. Now, I am scared to try things by myself but, how do I install a permanent recovery?

I booted up clockworkmod but it didnt found my device.

1. Apply from stock recovery.

2. DO NOT BOOT TO OS when update is finished. After updated, press power button until screen off.

3. Boot to fastboot mode by holding 'Power' button & 'Vol UP(+)'.

4. In fastboot mode, boot to custom recovery by

fastboot boot openrecovery-twrp-

5. Make a nandroid backup for data partition. (Optional)

6. Sideload

7. Reboot to bootloader(fastboot mode)

8. Extract and execute '' to update radio and other binaries.

9. Flash 30O system partition only by
fastboot flash system system.img
(Don't flash userdata.img or userdata_64G.img or you'll lose all your data.)

10. Reboot. The Bootloader is unlocked.

Sorry for my bad english.

Your English is great man, and thank you for this. I'll try it with my friend's One which he received last week.

A bit of a bump, but I just tried Hilmesh's method out with the newest 38R release and it worked great

I paranoid flashed 33R before flashing 38R and then SuperSU, but still, it worked and I still have all my data

Thumbs up
Im having 38R and want to unlock+root+put custom recovery without losing data. Can I do that without any ""25R->33R->38R" tricks on can I just use 38R and follow the instructions by Hilmesh?
I dont understand why in the instructions there is this "25R flash and then 33R flash". Is there some limitations with 33R, 38R and further, so 25R has has to be used?

Regards Mike

More, got the point. 25r does not need unlocking of bootloader, that is why we need to flash it. i went then 25r to 38r and everything worked perfectly. thanks!
