sorry, I read the guide better, it says how to do it, thanks.Re-read the guide a little closer. You can't just plug in the board and expect it to work. There is a specific process to flash a RP2040.

Didn't touch the emmc what so ever. And from the picture, yes it looks like....SOMEHOW....SOME WAY....I wasn't careful enough and ripped that, what looks like, 0201 resistor which looks like the trace goes directly under the APU. Potentially have a winner here once I can find the value of that resistor to be replaced. In ohms mode it read at 560ohms but can't be 100% sure. I hope this is it. Thank you because this gives me hope that my soldering and mosfet work was good.
Edit - Anyone know a good resource as to where to find a breakdown/diagram of switch caps/resistor values. Googling it for a while feels like taking a pedal-bike on a motorway, getting nowhere fast.
woops had it on 2k setting, turned it 20k and got 9.95k...and 200k mode gets me 10k. Alright, thanks again. And that size is definitely 0201!?Just checked a spare board, *both resistors show as 10k for me*
I tried to cut it but there is very little gap to place a clipper to cut. And You need a plier to cut it because port material is very hard. First heat the upper two joint and which will help you to tilt the port at some angle to put a plier in tu cut it. Cut two upper point and do the same on the below one. That's the technique I used. But after cutting all points, apply some heat to pads which will help the port to fall off.
** RST is not connectedhello, the reset point has already been changed and it measures the same on the board as on the chip, so it's ok, maybe that's the nand the problem. the firmware of the chip is 2.70
I know what 2 short pulses mean, but I measured the point on the board directly and on the chip after connecting the cable and they measure the same, that means that the point is fine, the problem is another** RST is not connected

I already shortened the cables and the same result, what nand do you have?Make a better Install with shorter Lines. My Installation runs without Problems.
Then why is reset not connected? Looks like you're missing a resistor around there too...I know what 2 short pulses mean, but I measured the point on the board directly and on the chip after connecting the cable and they measure the same, that means that the point is fine, the problem is another
the reset point is not disconnected, measured with the multimeter point 26 of the chip measures the same as on the board. As far as I know on the chip, only resistors are placed at points 27, 28 and 29. I have already made at least a dozen standard switches. I forgot to mention that I have already changed the chip and the same result, tomorrow I will try with the firm 273Then why is reset not connected? Looks like you're missing a resistor around there too...
I don't care what you "measure", your video looks like it shows that you removed the resistor near RST and then soldered the wire to the pico in its place...the reset point is not disconnected, measured with the multimeter point 26 of the chip measures the same as on the board.

I know what you're saying, it's that some boards come without that resistor, I didn't remove anythingI don't care what you "measure", your video looks like it shows that you removed the resistor near RST and then soldered the wire to the pico in its place...

here you can see a board equal to mine without resistance
I do not understand what you wantPictures or it didn't happen...
