Could it have been working fine three days before if it's the wrong soldering?must check it

it's not that complicated as you describing the whole install...if you want to uninstall just reverse the process witch is about 30 sec...i dont know what you have in mind...

Come on if you want to replace the fan or whatever you just unscrew the shield and lift a little bit the rp2040…I never said it was complicated, I basically just said it 'adds unneeded steps', and you're forgetting about the time to reinstall it.
Think your fan is never going to die? Never want to replace the thermal paste again? Sure hope you only charge with an official charger and never mess up plugging it in.
Can you give a link(or image) of where these other soldering points are?must check it

yes, its a toshiba but toshiba is supportedI've fully resolder, make data wires shorter, but still got blue->pink(or purple?). After soldering GRB/RGB points together pico shows blue->green lights (and starts ofw with 2101-0001 error). Also, can someone say do my switch have toshiba emmc or not?
Yes it can br cold solder , purple screen it problem with EMMCCould it have been working fine three days before if it's the wrong soldering?
yes, I noticed this problem at the assembly stage and fixed it, it's just that this is the first photo, 50 ohm resistors, other people put them, they also work like 47Your 50 (49.9) ohm resistors threw me a little bit, but those should be alright, considering you were booting. Is it possible that your wire attached to the resistor on pin 26 is intermittently hitting the ground pad of your removed button, and foiling the picofly glitch?
I've just received the resistors in the mail and promptly replaced the old resistors with them.must check it
As far as I know purple screen mostly bad CMD point or blown CMD resistor.Yes it can br cold solder , purple screen it problem with EMMC
When the purple screen happened, did you use emummc or sysmmc?Greetings! Another problem. Yesterday my switch was working fine. Today I turn on - a purple screen. After the reboot, it was possible to start the drain, but after a couple of seconds an error occurred. Through time it is possible to get into the recovery menu, even did a reset to the factory settings. But still purple screen or error.

After another reboot i have this:

It seems that the problem was really in the resistor, but I don’t know which one, so I replaced everything and it helped. At least for a while)When the purple screen happened, did you use emummc or sysmmc?
Is it charging?I've fully resolder, make data wires shorter, but still got blue->pink(or purple?). After soldering GRB/RGB points together pico shows blue->green lights (and starts ofw with 2101-0001 error). Also, can someone say do my switch have toshiba emmc or not?
Yes, percentage goes upIs it charging?
Going through the thread it seems that in most cases the error you are seeing is caused by faulty M92T36 chip.
So @Haseo13 was right, using different soldering points fixed the issue?Yes, percentage goes up
upd: forgot to mention - error disappeared after I solder ground to another point
At first I tried to solder on the one side of emmc and also resolder ground, but it didn't help with pico, same led colors. Will try different points later and post results. Also, is it fine if I solder on board only D0, CMD and CLK, leaving power and RST on emmc?So @Haseo13 was right, using different soldering points fixed the issue?
Yes, you can mix-and-match the soldering points as you see fit for your installation.At first I tried to solder on the one side of emmc and also resolder ground, but it didn't help with pico, same led colors. Will try different points later and post results. Also, is it fine if I solder on board only D0, CMD and CLK, leaving power and RST on emmc?

I replaced all threeIts not clear for me. So You replace the CMD resistor and now its working?
Anyway i'm almost sure purple screen is mostly caused by blown cmd resistor.
Also, when soldering to board, is it necessary to solder to one point, or i can solder to two nearby points(marked them on picture with red line on d0, cmd, clk lines)?At first I tried to solder on the one side of emmc and also resolder ground, but it didn't help with pico, same led colors. Will try different points later and post results. Also, is it fine if I solder on board only D0, CMD and CLK, leaving power and RST on emmc?
