Need help with a Nintendo Switch V1

Hello,

I bought a broken Switch V1 and it wasn’t booting up, there was a problem with the firmware on the emmc. Did a restructure of the system and got it working. Noticed that the device only charged one side of the USB C and decided to replace the port.

After this I can’t get the switch to boot up?! The new port take a charge only from one side. Tried removing the USB C port and boot from battery, but nothing changes… The pads looks good and haven’t tuched anything else on the board. No shorts around the M92, BQ or P13. When battery is connected I get 3,7 bolt from the battery to the MAX IC below the CPU. Something is stopping it from booting.

Do anyone here know what it could be?

Could a bad M92 chip stop the device from booting?

New update:

Used my bench power supply and followed the retrosix.wiki.

What I understand I can boot to 1 level, no shorts on the components that the guide describe. But it can’t boot to stage 2, it stays at 0.2 amp. I removed the emmc and get the same result…

UPDATE2: Tried installing Android, but this gives me an error to. Thought it was the emmc, but it looks like it’s something else hardware related. Is there a way to check the status of the RAM and CPU?

Would appreciate some help😁
