SWITCH CONSOLE DEAD,SX CORE SHOWS PINK LIGHT AFTER REBOOT !

[EAGLE-1]

hi guys, I have this case, have a patched gray switch, honestly I'm not sure if it's mariko or not what if we knew it was not compatible with sx pro, then we installed the sx core, the console started perfectly, until the switch menu, the sx core was updated to 1.3 and the sx os is in 3.03, so far so good, the console is updated with Choi Du Jour NX to firmware 10.04 and everything perfect the console was restarted and all good, I already had the console with sx core in 1.03, sx os in 3.03 and the nintendo firmware in 10.04, BUT to put another micro sd I had to turn off the console, after that moment the light of the sx core chip turns on only in pink, according to the manual is due to a bad solder but it is not like that since everything was working perfect, however I connect the chip to the pc to update again to 1.3 and the pc doesn't detect anything, I even put another sx core chip and nothing, already I just need to re-chip again but I am sure that is not the problem, now well i have the backup of the console nand, can i do something with that backup using pc utilities for restore the console ?? thousand apologies for the long post but I wanted to explain the case in detail, thank you very much for any help
update.
I already removed the chip completely and the switch still does not turn on

if you used choij to update sysnand
you are bricked and only the chip can bypass it.

the detection on usb debug is hit and miss you just need to keep trying, it should light up when plugged in to usb

hi,well i dont know about is i update sysnand i think so,the strange thing is that the console works perfectly after updating to 10.04 with choij even I did tests with some games and everything was fine, the chip turned on the pink light just when I turned it off to change the micro sd and also before turning it off in the sx menu I saw a message saying "can't communicate with sx core, please check your connections" something like that was the message and after that it didn't turn on anymore, so i ask, should i reinstall the sx core? but the pc does not detect anything, the light turns green but the pc does not detect the chip, I also have the NAND backup, can that help me to restore the console? Thank you very much!
