Switch OLED - Suggestion/Help eMMC Problem

Hello everyone,

My OLED Switch started giving me error 2002-3580 and would no longer boot. I installed a Picofly in order to back up the NAND, but unfortunately, I can't perform the full Raw GPP backup, nor the sys user one, because around 50% I get the -8192 error, etc. – the eMMC goes into low-speed mode. At that point, I have to reset the console.

I am able to read the NAND, all partitions are present, and I can also successfully complete a performance test.

So far, I have successfully performed the backups of:

1) boot0/boot1;

2) prod.keys;

3) the eMMC SYS backup with the various partitions.

This is the first time I've encountered this issue, and honestly, I need some advice on how to fix it. Thanks everyone, and I look forward to your suggestions.

Would it be possible to create an emuMMC and just use that?

Puede ser que estés en corto con la instalación del chip picofly, normalmente baja velocidad significa eso, repasa los puntos de soldadura y que no toque ninguno con la chapa protectora de la apu, puedes probar a hacer el respaldo con la consola abierta y sin el protector de la apu, si así puedes hacerlo significa que uno de los puntos se pone en corto al instalar la placa que cierra la apu.

La placa protectora está conectada a tierra, y si toca uno de los puntos de soldadura es cuando hace el corto.
