Team Win Recovery Project is a custom recovery for Android devices.
It allows you to back up and restore your data, flash custom ROMs to your device, repair broken file systems, root your device and more.
- I do not claim this work as my own, this thread was created to have an XDA thread for A71 TWRP. I will try my best to keep it up to date with Ian's work, but can't promise that will remain for ever. If you want the latest TWRP and to be notified as soon as its published, be sure to join the Telegram channel.
- I am not responsible about any damage of any kind that this custom binary may cause.
- Please read the whole main post & related ones before proceed and follow the guide as it is wrote. I will not offer support for any issues that have been already stated.
- Your Knox Warranty Bit will be blown once you flash this or others custom binaries, preventing you to use Knox Features. It can't be resetted in any way, so think twice before flashing this.
- Bugs can be reported here in XDA or via our Telegram Group. Please be more clear as possible and make sure you provide detailed info when reporting bugs (device variant and logcat).
How to Install:
First, you need to unlock the bootloader. Here's how to do it:
- - Backup all media before proceeding, this will erase everything in your internal storage including music and photos
- - Go to developer settings and enable [OEM Unlock]
- - Reboot to download mode
- - When prompted, press and hold VOL + to enter bootloader unlock mode
- - Press VOL + to confirm you want to unlock bootloader, this will wipe your data
- - If you think the bootloader is fully unlocked, it is actually not! Samsung introduced VaultKeeper, meaning the bootloader will still reject any unofficial partitions before VaultKeeper explicitly allows it.
- - Go through the initial setup. Skip through all the steps since data will be wiped again later when we flash TWRP and magisk
- - Enable developer options, and confirm that the OEM unlocking option exists and is grayed out. This means the VaultKeeper service has unleashed the bootloader. This step is MANDATORY
- - Your bootloader now accepts unofficial images in download mode.
After finally unlocking the bootloader, proceed with installing TWRP (tar) with Odin:
- - Boot to download mode and load TWRP tar file and VBMeta disabler tar file in AP and BL of Odin, doesn't matter which goes where
- - Disable [Auto Reboot] in Odin
- - Flash
- - Force a reboot by pressing VOL+, VOL - and POWER buttons at the same time
- - After the screen goes black, IMMEDIATELY let go of all buttons and IMMEDIATELY press and hold VOL+ and POWER button at the same time to boot to TWRP
- - After booting to TWRP successfully, go to WIPE in TWRP
- - At the bottom, you should see an option to FORMAT DATA. After you select it, you will be asked to type "yes" in your keyboard. If you do not see this, you probably selected the wrong option.
- - After formatting data, flash the Multidisabler zip with TWRP. This is done to avoid future bootloops.
- (Optional) Flash magisk.zip to root (google where to find it)
- - Reboot to system
- - Wait patiently for the device to boot for the first time
How to flash TWRP (img):
- - Reboot to recovery
- - Select Install
- - Select Install Image and search for the TWRP img file
- - Flash as recovery
- - Reboot to recovery
- - Done
