White / Light Blue Led after installing SX Core

[Ds5431]

Hi, yesterday I installed an SX Core to my switch. it had trouble reading the sd card at first but after changing it for another brand it booted to sxos, it updated itself to version 1.3.

I starting doing the nand backup and went to bed, today in the morning the backup was done. I turned the switch off and now when I turn it on the blue light blinks and becomes a light blue / greenish / white ligth and nothing shows in the screen.

What could it be happening? I have read about the pink/ red light but this is not it, I thing the blue and green leds are the ones on.

Thank you

For some reason, after some manipulations on your SD card, the chip can blink blue a lot of times before turning green. You might even have to try few times before it works again.

I guess you didn't have time to create the emuNand. Copy all files relative to your dumped sysNand on a safe place on your PC, then rename the sxos/backup folder on your SD card into sxos/emunand.
Make sure "boot.dat" and "licence.dat" files are still at the root of your SD card.

Put back your SD card into your Switch and try to turn in on insisting on Power button until it turns green.

I think it was a bad connection on the flex cables, I disconnected all the pieces and put it back toguether a few times and finally the led turned green after blinking blue.

I copied the dumped nand and im doing the emunand now

I also tried booting the system without the sx core, with the nand in his original place but without desoldering the pcb from the soc and the switch didn't boot either, is this normal?

thank you

I have the same problem, just reformat the memory card system and remake
