Oled picofly switch not booting

[Camo702]

My switch was working fine the other day until I rebooted. Now it won't boot at all.

The LED error code from the Picofly chip appears to be short long long.



I did not install the chip but is there anything I can do to figure out what went wrong or to fix this.

Here are some pictures of the install:

Please, anywould or insight that can be provided would be greatly appreciated

*== error code in most case is MOSFET/CPU FLEX solder problem.

close up picture of SP1 SP2 soldering please

From the PicoFly guide: *== No eMMC CMD1 request (poor wiring, or dead CPU).
Recommend checking your diode readings with a multimeter.

Wire broke off from the ribbon cable after I took the picture. Should I resolder it to the same point?

What setting should I set the multimeter to and what should the readings be?

sp1 left side seems broken but that's ground. The right side not too clear with maybe thermal paste on top. The sp1 cap seems twisted not straight compared to how sp2 cap looks like

this middle entire line is the CPU pin to rp2040, do whatever you want.

I disconnected all the wires from the chip and the console will still not boot to OFW. Would that mean the CPU is likely dead?

CPU will not be that easy go dead, But you have permanent dat0 soldering so I don't think that would be data corruption either. Maybe other hardware issue
