I modded my switch with a “New 2040 plus” (it spells out like this on the flex cable) chip. After soldering everything I check for shorts and found none. I then started the switch and got the “No SD card inserted” screen.
I put everything back together and plugged in an SD-card with hekate. It booted up perfectly and when i tried to boot both CFW and OFW i got a bluescreen.
I disassembled everything again and checked for shorts again, couldn’t find any.
I removed the RP2040 and let the soldered flex cable stay, the switch booted to OFW without problems.
I then plugged in the RP2040 again and started doing backups, this is where the weird thing happened. The screen started turning on and off during the backup and ending in the screen turned off.
After this I won’t get any signs of life from the switch. I removed the RP2040 together with the soldered flex cable to bring it back to stock but the switch is still dead.
I’ve checked every cap on and around the SoC and cant find anything wrong.
Any tips on what to look for?
