Before level 3 NAND Fix Pro, my switch can't entering Stock system, always black screen, no nintendo logo shows, no error messages. Carefully read level 1 and level 2 repair prerequisites, and I decided to run the level 3 rebuild.
Donor keys is from my another working switch, and firmware selection is according to Youtube tutorial as 20.5.0.
Everything goes fine with Level 3 rebuild to the very last steps, no error / unsuccessful messages.
But, as the tutorial, when choosing entering CFW (SYSMMC), there's only "INI1 parsing failed" message, same goes with CFW (EMUMMC), and as for 100% Stock option, I got "No mandatory pkg1 files provided! Failed to launch HOS!"
Had tried running lv3 with 12.0.2 and 21.1.0, with no luck.
Desperately need help here, thanks in advance.
