Samsung Galaxy A31 [SM-A315G/F] [a31nsxx & a31xx] - Team Win Recovery Project

Telegram Support Group

+ TWRP Status: Mostly Stable. 
- Releases tagged as "Pre-release" are considered experimental and may cause more unexpected stuff than the latest release, nobody is forced to support your in older releases.

Set the TW_CUSTOM_THEMEflag for a custom theme.

Build with twrp-11 to avoid the recovery.img being bigger than the partition.

Run chmod +x device/samsung/a31/mkbootimg to avoid building issues.

Special thanks to:

TeamWin for the Recovery Project.

Physwizz for his a315g-S kernel (ligther version was used on this tree).

Zillion for doing the device tree.

How to install

Flash the latest .tar release from releases, it may require Magisk patched vbmeta.img

Hold the recovery combination (Volume Up + Power) while the .tar is flashing via the odin tool.

Flash any multidisabler that has been tested on a31.

You can now boot into your system and do whatever you want.
