I’m looking to upgrade my Ender 3 Max Neo.

It has Marlin 2.0.8.3-HW-V4.2.2-SW-V1.4.7G firmware which I am unable to flash over to other versions of Marlin for some reason, it just crashes.

My board is a 4.2.2. Obviously as indicated by the note above.

I don’t mind changing the board out but I’m having a hard time finding any information on the 3 Max Neo and would rather not buy parts just to end up finding out that it’s not going to work.

Any help would be greatly appreciated.
