Hardware Blue screen switch, think its dead!

[lpoolm]

So i got a bundle of faulty switches, the usual not charge etc.

But this one is just blue screen.

When I got it it would not turn on but plug it in with genuine charger and it turns to a blue screen, try it with my usb adapter that shows what amp/v it gives and it does not show anything or show anything on the adapter?

I have since plugged it in to my laptop to put it into rcm mode which to my surprise it did but there is corruption (see pictures) however this is good, most of the time there is pixelation across the whole screen.

I have noticed it will not boot into rcm if there is an sd card inserted? o an issue trying to dump the nand.

I have started it then inserted an sd card but it fails when I try to back up the nand. I have tried a different sd card reader so that is not the issue.

I opened it up checked the usual chips for shorts, all seem good.

So after reading through a few threads not many I am thinking this maybe un-repairable, may just be able to remove some chips for other boards?

It now does not go to blue screen when plugged in? not sure if that is good/bad but will turn on to below screens through rcm.

I did try the reboot options but just goes to a black screen!!??!

Any input would be great before I right this one off too.



thanks

yikes... idk what to say, mostly because I don't own a switch.

Yep, I am 100% sure about this as it happened to me as well.
The Boot0/1 are corrupted or 'wrong'
dump your rawnand using hekate and follow this guide, then just flash the boot0/1!

(I might be wrong but it's worth a shot!)

i might have read your thread then!
did you manage to fix it or is it gone?

I didn't use that method but i did have the same blue screen of death when by boot files were incorrect
so following those instructions might help !
