Hardware Homebrew I modded a bricked Switch - CFW not booting

[MechaBronics]

Hello everyone!

I bought a used, defective Switch Lite from an Online Marketplace to experiment with. It used to show the Nintendo Logo and then go to a black screen, nothing more.
I asked what to do with it on the BitBuilt forum and they told me to install a modchip. I did and it loads to the hekate menu with no problems. After following the setup guides on switch.hacks.guide the Switch just refuses to boot into emuMMC or SysMMC. It shows me the boot logo and then the console just goes black. I even have to click the Power-Button to go back to the hekate menu.

Does anyone know what i have to do to get the CFW running?
I originally wanted to use the modchip to unbrick it using NXNandManager and EmmcHaccGen.GUI but the water damage sticker on the motherboard was pink, meaning CFW is my only way to go since the NAND chip most likely suffered from corrosion.

This, leads to:

The original NAND was damaged so the emuMMC created from the corrupted NAND will behave in the same manner, no surprise there.

You will need to rebuild the NAND using the console specific keys and a clean NAND copy. Check on Youtube for Sthetix NAND repairing for diferent level videos.

Hmm well this sucks. I will try that for sure. In case the NAND is un-repairable, can i still use the Switch for Emulation by using Linux/Android or are these created from the NAND similar to the emuMMC?

You should be able to repair the NAND with a donor NAND (some images are floating around the internetz afaik).
Make sure you get an image for the same model.If successful, the only thing you can't do is connecting to Nintendo servers.
So no online gaming, getting updates from Nintendo or buying games from the eShop.
It's just like a banned Switch.

Afaik, you need a working NAND or at least a proper BOOT0/BOOT1 partition to make Hekate start CFW/Linux/Android
But if you see the Nintendo Logo, then those 2 should be fine.

Sound like problem with the sysNAND

Hi my friend,

i have attempted other things that don't seem to be working so the donor NAND solution had me quite curious.
Is this a hardware solution where i have to swap the nand chip with a working one or am i misunderstanding something?

NAND Rebuilding Guide

This rebuild of NAND is to use donor NAND from Switch (A) (which you may obtain from internet) with device ID (A) on Switch (D) which certainly has device ID (D)

It means that we are tricking the Switch (D) to see itself with device ID (A) so it will boot into NAND with device ID (A) encrypted by keys from Switch (D)

By this method, you can't go online and can't boot OFW
In theory, if the files are modified to match device ID, it should be possible...
