Just installed the rp2040 custom board on my lite and it works great except for a few hiccups.
I managed to fix these issues in case someone runs into:
The boot and rst buttons are a bit high on the lite, they can be removed.
The LDO (the chip in the red box in the picture) has to be removed or it would break and cause problems, after a day of playing the console suddenly gets stuck and the CPU buzzed and it wouldn't power on, I thought the CPU was dead, but everything went back to normal after removing the LDO, looks like reverse current killed it.

Hello, can anyone help me :(? I damaged the right pad of cmd and my switch lite didn't turn on. I've reconnected the line, checked the connection again, but the switch still won't turn on. I installed the chip, it flashed purple, checked the connection at cmd clk but the switch still couldn't turn on. Is it because I messed up my emmc or something wrong?

Well. at this point, if you've removed, and replaced, and removed, and replaced that little flex cable over the battery connector in your lite, then it's possible you've got your console booting again, but you've killed part of the screen circuit...

Or you have been plugging the battery in and not plugging that flex cable back in, in which case, your screen won't turn on, because that goes to the daughter board that helps run the display.

plug it into your pc and press power. It should detect RCM mode, if it does something isn't connected properly

It is either the cmd has not been repaired or is not connected properly.
Flashing purple is a cmd error.

I shorted the 3.3 v point to the capacitor next to it, damaged the element on the back of the board, help me locate its value

already used a different card reader. I've noticed this since the 2.65 update. Also blue screen now on ofw. Even with the picofly removed
I had the same issue (only IPL works, blue screen with OFW) on Lite with damaged power IC MAX77812, replacement fixed the issue.

Please check the power IC and capacitors around it, could be the CPU power problem

Even if this was working with OFW prior to installing picofly?
