Hardware Useless work on ns oled

[romchik971]

Hello there. There is gonna be kind of dumb question. It just happened that I have m92t with 3 broken pins
I bought ns oled for spare parts couple months ago. It I turned out that it had broken emmc. Yesterday I used blank nand with picofly and it worked LOL. Unfortunately I already swapped bq, m92t and p13 from it. I already replaced all of them, and except for m92t are brand new. As I know, console can boot up even w/o m92t, but with error after switch logo. I used sthetix guide for unbricking console with prodgen etc, but I ended up with purple screen. So Im trying to figure out, is this issue comes from partly broken m92t, or am I doing anything wrong. I'll pin picture and mark ripped pins
P.s suspicious thing no.1- 209 prod keys in lockpick rcm instead of 190 I always get, no.2- after I restore boot0 and boot1 from donor nand, it's size doesn't change in emmc info.
Im looking forward to any advices. Thanks in advance

A purple screen is usually some sort of kernel panic when the bootloader can't be read from the emmc .
Either data corruption or some hardware damage to the communication lines to the emmc.
If this is a failed mod attempt by the previous owner, just inspect the board for any damage around the shields.

I think the M92T is needed because if Nintendo can't confirm that the battery is healthy, it won't let you boot the OFW.
That is why the Switch won't work without a battery installed.
You will be able to boot into Hekate though.

What error did you get after the Nintendo logo?

There was no mod attempts by previous owner. It just died after update (LOL) I've done mod by myself to see fault codes. All battery info seems good in Hekate. I'll try to restore rawnand as emummc partion today, just to make sure it's no emmc problem. I just wonder if this m92t pins are necessary for full bot

Upd. Seems like the nand is trash. After I've done couple attempts on restoring boot0 and boot1, and now it no longer launches. Just shows emmc read/ write error. Looks like I'm gonna format it with bga-usb stick and try to restore emummc only. Hope it'll work
