I am not responsible for anything that happens to your phone or computer. You have to understand what you are doing.



One-Time Boot
  1. Enable ADB debugging (in Developer Options)
  2. Reboot into bootloader / fastboot mode (adb reboot-bootloader)
  3. Boot into recovery.img (fastboot boot recovery.img)
  4. Done!

How To Flash
  1. Install ADB+Fastboot with drivers (I recommend this installer)
  2. Enable ADB debugging on your phone (in Settings->Developer Options)
  3. After connecting the phone to the PC, pop up may appear, tick Always allow from this computer and click OK
  4. Extract downloaded recovery zip and copy .img file to C:/adb
  5. Now open cmd line (press Start+R, type "cmd", press OK) and go to C:/adb (type "cd C:/adb" and hit Enter)
  6. Reboot into bootloader (fastboot mode) (type "adb reboot-bootloader")
  7. Your phone should now reboot into the bootloader (Little green android logo in the middle of the screen)
  8. Flash the recovery.img (type "fastboot flash recovery recovery.img")
  9. (*) Now boot into the recovery (type "fastboot boot recovery.img")
  10. (*) Mount /system partition (In TWRP go to Mounts and tick System)
  11. (*) In TWRP open File Manager, go to /system and rename recovery-from-boot.p to recovery-from-boot.p.bak
  12. Finally, reboot!
  13. Done!
* You should do these steps only if you have Lollipop firmware (to prevent from TWRP being overwritten by stock recovery on each boot)



Download

TWRP 2.8.7.1 (18.0 MB)
TWRP 2.8.7.0 (19.5 MB)


CN Devices
There is limited support for CN devices although most features (backup/restore, etc...) should work fine.
I don't own CN device, therefore I can't "add" full support for them.


Check out my script for switching between UIs under TWRP!

I know it's not that straightforward. You have to have adb and fastboot installed somewhere, then copy the .img file there and execute those commands in cmd line from that location.

One thing I forgot to mention is that you have to delete recovery-from-boot.p file (i think it's in /system) before booting into android, otherwise your custom recovery will get replaced with the stock one.

I'll try to rewrite the guide tomorrow.

Try to be polite and not just the "smart" guy. Electry was so kind to give some explanations ......

Confirm problem
I have the Chinese version of K920.
Everything was ok until confirming the system/recovery.from.boot.p file rename.
I can not confirm. I should swipe to confirm, but it do not work. And when I unfortunately touched the power button, the whole operation was locked. Now I have a kind of an Icon in the lower left part of the screen parly hidden. It is a padlock and a text saying "...t to Unlock".
How to solve this?
