If I remember correctly, the pulldown resistor installed on the mosfet is not needed for the glitch. It is just an extra precaution to protect the rp2040 board if the mosfet burns out. Make sure your points are clean, you should use more solder on the mosfet and clean your flux or use no-clean flux. Check for shorts to ground and double measure everything. If you follow these points and the guide you should be fine. redo the install if needed, post pictures if you need help. Good luck!
thanks for your answer,
I have done hundreds of installations with a mosfet (IRFHS8342), but with the IRF8714 there is no case, and I thought that this resistor was necessary
Bro your a life saver thank you so much i tried 2 professionals to take a look and they didnt got it, you just saved me in a 5 mins DIY XD love you bro

Soo, let's pretend that I didn't ripped off the rest of the rst trace(the one on the right) is there any way to connect to another place? ( almost crying because I forgot to put resin on top of it
)

Might be wrong, test the continuity yourself before using it.
I tested that the emmc connector lead to that upper point on the bottom but I need to find where it come from to get to this red arrow(I need to make a bypass

I really like this. So much better then the Adapter. Is there is a template you use or just roughly the same spot. Thx.
Two things
You have a spot of flux
The adapter is no good. I doubt you even have it aligned

Always in the same place, I go slowly completing each layer and cleaning to be able to see, a drop of liquid flux to hydrate and to be able to see through the layers. I scratch the line just enough with a pin and reveal it. Green nask around, flux, tin, I connected an enameled wire and secured it with hreen mask, first the hole and then the run. A slight tug tears off the line.
Yesterday doing internships I managed to change a SKhynix nand for a Samsung and restore the backup, take the opportunity to put enameled wire and get a permanent line.

All flux has been cleaned and I’ve used more than one adapter. Has to be something else.
But does it boot original? It may be that the ball of the DAT0 has deformed and that the tongs of the adapter are touching several points below the eMMC. Try cutting the left fork if you use the adapter
It was late last night so I didn’t try getting it to boot into ofw. Do I need to disconnect the whole thing? I did a reflow on it and I still get the same readings.
