Team Win Recovery Project (TWRP) is an open-source software custom recovery image for Android-based devices. It provides a touchscreen-enabled interface that allows users to install third-party firmware and back up the current system, functions often unsupported by stock recovery images. It is, therefore, often installed when rooting Android devices, although it isn't dependent on a device being rooted to be installed.
This is the official build (beta) based on TWRP sources and xiaomi blobs ... fully working !
(Mi 9 Lite / Mi CC9)
!!! IT'S NOT MY PROBLEM, IF YOU DON'T READ AND FOLLOW MY INSTRUCTION CAREFULLY, IF YOU DON'T HAVE TIME FOR THIS, OR IF YOU FLASH SOMETHING OR DO A MANIPULATION I DIDN'T MENTION HERE !!!
THIS RECOVERY DOESN'T SUPPORT ANY ZIP MOD/ROM THAT DOESN'T USE SYSTEM_ROOT MOUNT. CHECK OFFICIAL TWRP HOMEPAGE FOR MORE INFORMATION ABOUT NEW A/B DEVICES FROM 2019
Installation Procedure (first time) :
- Unlock your bootloader ()
- Enable ADB from your Official MIUI Developer option
- Plug your USB cable to your Windows PC and type :
adb reboot bootloader
- type then :
fastboot flash recovery twrp-3.3.1-0-pyxis-final (auto-decrypt).img (rename your image just by twrp.img)
fastboot flash vbmeta vbmeta.img
fastboot reboot (keep Vol+ pressed until you see TWRP splash)
- Wait for decrypting ... (if already you set a lockscreen pattern or a fingerprint)
- Format Data (button on the right) + Type "yes" on the keyboard popup
- To boot TWRP from MIUI : reboot menu + keep Volume UP pressed.
- To boot from phone off : power button + Volume UP
TWRP can now auto-decrypt your crypted /data partition so you can make backup with no issue.
This is a big fix that prevent to loose your fingerprint and pattern ...
For MIUI users, you must flash the fstab.zip fix after flashing your MIUI rom !!!
Update : 2019-11-05
-version : 3.3.1-0
-stable and optimized : setting lockscreen pattern and fingerprint on the first boot is no longer needed !
BE SURE WHEN YOU WIPE YOUR DATA, YOU KEEP THE "4 FOLDERS BELOW + .layout_version". THESE ARE YOU ENCRYPTION DATA. IF YOU DELETE THEM, YOU WILL NOT BE ABLE TO RESTORE YOUR DATA BACKUP UNTIL YOU FORMAT YOUR DATA AGAIN.
TRICK TO SAVE YOUR LIFE : ALWAYS KEEP YOUR BACKUPS ON THE EXTERNAL STORAGE !!!
