A30 Marlin test and back

[apak]

I just flashed marlin to GMT32 mini (A30 board) and run some tests. Did a autotune for PID (e3d v6 hotend). Complile again to reverse direction (tmc2208) and some other stuff. Didn´t even try to print.

BUT!!!!!

Could not get back to smartto, I flashed regular FW files, but didn´t work.

I guess I wrote over the bootloader, so the board didn´t start properly.

Didn´t find a bootloader file to GMT32 mini, so I just dump my E180 flash into PC.

Later I flashed back E180 file to A30 board, and got it back to live.

BUT!!!!

Now A30 s/N is E180 and version number is also E180´s.

Is it there a way to restore S/N and HW version back to A30 originals?

Have picture of it from unboxing.


TIP: If your are going to test marlin, SAVE A DUMP of your flash first of all.
