I have not found manuals or diagrams. The big chip is the ic charging chip. The smaller ones near it do not have any numbers so I think I will search for broken tablet boards to find anything similar
The big chip is axp288c
Thanks for the reply. I did this step. I always enable external FIRMs and modules since i play vc gba games. Maybe is something else i am missing. Forgot to tell i am using the last build of TWLMenu++. My console is the old 3ds xl model.
