there is a small range that works

47ohm - 51 ohm shouldn't have any issues

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.

Point 5: Alternative points.

What are the alternative points you mention? Are they on the motherboard or where? On switch lite?

Erista boots into picofly but won't boot Hekate. Blackscreen when I put the SD card in. Thoughts?

Try reseating your SD reader board at it's connector/see if it needs cleaning, or a pin is bent.

have you managed to repair ur clk trace yet?

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

nah, its beyond my skill, I'll be sending it off to someone when I can be bothered

Also tried several sd cards and formatting. No luck

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

do you think modding v2 is easier?

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?

In my case it was accidentally physically damaged during the modchip installation.

Since it boots into the IPL, the basic things like eMMC and CPU should be working. Looks like the power circuit is damaged somewhere
