WOOOOOOOOO
So I got antsy and didn’t want to wait.
So I threw some amtech on the board and reflowed the fuel gauge chip and then the diode measurements matched my dead CPU board which is also a early version.
Tried to power on and the same thing happened just the Nintendo logo but this time it would only come up once and the never again until I unconnected the battery and then reconnected it and pressed the power button, I also noticed if I plug the battery in and then the charger the charging icon would appear for 2 seconds and then go away.
So I thought it was the bq chip I checked the via diode mode and they were similar to my dead CPU 10 board expect on some caps which I think was dude to the unfixed shorts on that board.
I then was thinking about this one website talking about emmc mismatch issues and failure to boot blah blah using a ociliscope to see if it’s the wrong emmc and failure to decrypt, so I just started swapping the emmcs and I guess I got them mixed up because it booted up fully YAY!
TLDR: getting Nintendo logo every time I pressed the power button, diode measurements were off on the fuel gauge chip, reflowed it then measurements lined up with somewhat same gen board, then I got different symptoms, the Nintendo logo appeared only once unless the battery was connected and reconnected, same with charging icon once charger was connected, swapped emmc to the correct one and it works now. (They got mixed up) (also swapped a ugly cap near the ENxx chip)
@jkyoho @Severence love you thank you for the help, I’m super inexperienced with fixing switches so I really appreciate the help.
