Oh snap! Just when i thought i was getting somewhere. Re - the 3.3v point, thats the point im already using for the Lite!?Thats an inductor, it is supposed to be shorted i think (if we are talking about the circled one)

My bad on the 3.3. Thats GND connected there, you are OKOh snap! Just when i thought i was getting somewhere. Re - the 3.3v point, thats the point im already using for the Lite!?
No probs. Got any theories on what i could be? The most I can think is either short or emmc. What ya guys thnik?My bad on the 3.3. Thats GND connected there, you are OK
I'm like 95% on emmc...if it was a short you would have bigger problems i thinkNo probs. Got any theories on what i could be? The most I can think is either short or emmc. What ya guys thnik?
thanks, going to research emmc stuff. more thank likely its that.I'm like 95% on emmc...if it was a short you would have bigger problems i think
Code is ==* CPU always reach BCT check (no glitch reaction, check mosfet)Just did an install and this is the code I’m getting. Used the mosfet method. The blinks are yellow. Any help would be appreciated
Read the guide in my signature.Just did an install and this is the code I’m getting. Used the mosfet method. The blinks are yellow. Any help would be appreciated

2 long 1 short, show your mosfet workJust did an install and this is the code I’m getting. Used the mosfet method. The blinks are yellow. Any help would be appreciated
Just get another pi pico, flash 2.74, and this time just remove the transistor for dat0 solder point in pico board, then assembled all the wire, then power on.. if like you said that your switch board soldering in fine then it should boot to sdcard screen.
Pi Pico is a rather tricky, but ive done multiple units with Pi Pico and in the process ive lost/burn/broke 4 pico boards.
yep dont add pain to yourself, buy new one as simple as that
Here I attach photos of my setup, sorry if it looks a bit messy, I can guarantee that is well insulated and the MOSFETs seem well soldered (even if it's not clear in the images).Any detailed setup photos?
I'm sorry, but you need to improve your soldering skill if you want to cleanly perform this mod.Hello! I managed to replace the pico with a new one so I can use the latest v2.74 and now I can see the error clearly!! It's ==* which means CPU always reach BCT check (no glitch reaction, check mosfet). I desoldered and re-soldered the two MOSFETs multiple times and replaced them just in case they were bad, but I keep getting the same error and then the Switch boots normally, so idk what to check.

I know hehe, I was hoping it could work out as long as it's physically soldered.I'm sorry, but you need to improve your soldering skill if you want to cleanly perform this mod.

jays right. It takes practise. You just have to git gud. Heres my method i did recently with a 10k pull down resistor bridging the mosfets' gate and source Covering each point in solder mask. Patience is king otherwise it won't workI know hehe, I was hoping it could work out as long as it's physically soldered.
I would love to do it better but the issue I had with the MOSFET itself is that it's really hard to keep the solder in its tiny pins, it gets out really easily when I try to solder the cables, so I end up putting too much solder in order to at least keep it there. Also, if I'm too near a pin I already soldered, the temperature ends up desoldering it again. I lowered the soldering iron temperature but helped just a bit.
Any tips or recommendations for making it cleaner without ending up so fragile?
Btw I'm seriously considering replacing the MOSFET with a bigger alternative.
Just search in here theres lot of successfull mosfet alt.I know hehe, I was hoping it could work out as long as it's physically soldered.

did you have this ==* code?Try to check the dat0, maybe its SC with others.
In Oled i experience the same.
You might try to increase the resistor of CMD/CLK/Dat0 to around 100ohm. Usually by add another 47ohm.
for me if thats happens most of the times its the mosfets installations, try using flex v1 or v2 so much easier and took afew second to instalHello!

Buy bigger mosfet 5x6 mm package should be easy enough.I know hehe, I was hoping it could work out as long as it's physically soldered.
