Hacking Hardware Switch Oled with Picofly Only Hekate booting, Nintendo Logo than BS

[Nafets359]

Hi, sorry for my bad english this is not my native language.

Yesterday i got a bricked oled Switch. When Trying to launch ofw or cfw it shows Nintendo Logo but than, Black Screen.

it has a installed Picofly inside.
First i completly resoldered everything to have a clean base. But it looked great before my resolder.

It boots to Hekate, Battery Info and Emmc Info seems good. I Also have prod.keys and prodinfo (From Atmosphere Backup Folder).

What ive tried :

1. Nandfix pro Level 1-3 unbrick
2. Emunand SD File <- with this it boots cfw better but gives a error :
Error Code: 2162-0002 (0x4a2) Program: 010000000000001E Firmware: 21.1.0 (Atmosphere 1.10.1-master-21 c0f75a2)

Maybe someone has a idea what is corrupt in this Switch?

It can be a ton of things.
First check if your PRODINFO is blanked, Atmosphere does not allow this anymore.
If a file called 010000000000002F exists in the atmosphere/contents folder, try deleting it.
A messed up Atmosphere configuration can also cause this (MITM settings in particular).

In Hekate you can check if your emmc partitions look good and if the fusecount isn't the problem.

It can also be a hardware issue like something broken related to the Wifi chip but assume that it is some software issue first.

Atmosphere is a complete new installation Ofw is also not working. Black Screen after Nintendo Logo.

im not an expert and writing this from my memory but download NxNandManager on your pc. get a usb 2.0 cable. in your switch go hekate - usb tools - read only on, click emmc gpt - in Nxnand manager go to left upper screen find open devices select your switch - open the same menu click properties. it should show you some stuff about your switch (serial number etc)

Hallo, so atmosphere has a file (int the atmosphere folder) called exosphere.ini, here it may have an option called blank_prodinfo_ = 1 or 0 (1 is true 0 is false). If it's on 1 set it to 0. you need fussee.bin to do that. blanking prod info is basically stripping away the identity of your switch if nintendo finds you using backups. that specific Program: 010000000000001E is attributed to verifiying user accounts (blanking prod info will make this impossible)
