Supported variants

  • SM-A310F: Choose samsung-a3xelte.
  • Adding support for one of the other variants is likely trivial.

Installation

Unlock oem mode via developer options android first to disable FRP lock. Advised to install twrp first for recovery options: https://twrp.me/samsung/samsunggalaxya32016exynos.html (see heimdall issue below for fix)

Note: Enter odin download mode by pressing Volume Down + Power + Home button. Pressing the Volume up button additionally will bring you to the Samsung Download mode.

Please also note that flashing from linux is broken with the latest heimdall released. It will start the session but fail to send the first byte. Please also note that after each attempt you should restart the phone in odin mode.

see https://github.com/Benjamin-Dobell/Heimdall/issues/347 for the error explained. https://github.com/alexax66/Heimdall includes the hack to make it work. Clone the repo and do:

mkdir build
cd build
cmake -DDISABLE_FRONTEND=ON -DCMAKE_BUILD_TYPE=Release ..

Then you find the heimdall that works for this phone in the bin directory.

Please note once twrp is installed it seems to work better to flash via twrp sideload instead.
