Switch Unbricking Guide - ProdInfo Fix (PikaFix)

yeah ur right!!
for first console, finally it booted,
but for second console, still nothing happens, i think i'll bring back to become l4t ubuntu again

 

by any chance a G drive / 1fichier / mega link. I am getting 275 kb/s, gonna take 3 hours

 

incognito put on sysnand/emmc, then prodinfo.bin/prodinfo.dat gone, then idk, what my friend do to those console, so error code appears like that, lol
lucky is not mine

 

Sorry, I forgot to say I was downloading from anonfiles. I'm reuploading to google drive now.

Thanks for the guide

Gdrive 1fichier

 

Does pikabrick do more than corrupting the prodinfo?

 

Hi Guys. I have a bigger problem. It has become completely strange. My bricked switch gives 3 different error messages. In Hekate at CFW he gives a PKG2 error, in Atmosphere a key derivation error and in Hekate StockFW a PKG1 error. I am now wondering which of the errors is the right one that is causing the brick. Have one of you can confirm that‘s this method have fix this errors because i have tryed two other methods there didn‘t works

 

Is this tutorial suitable for repairing my lite

 

Really was hoping this guide would work for me but sadly nope...
Im still stuck on the Nintendo logo no matter if I boot in stock or CFW.

I tried following the guide step by step... and I STILL get stuck on the Nintendo logo... even worst...
The screen goes black the moment it shows the logo when I boot up Stock
4 years with this switch. GONE. Cant find any solution to fix this.

 

Only back up I did prior to the guide, was a Boot0/1 and rawnand.
Although I dont know how much help it would have been to back up since I mistakenly hit the update button by mistake and ruin my CFW. (forgot to do a nand/boot backup before ever homebrewing my switch)
Been trying to fix it ever since, for awhile now... every time I booted in Stock or CFW. My screen would display an error message right before showing a black screen. Turned out..
My emmc was fuck, so by using gptrestore. I restored the original Switch GPT to my eMMC.
Manage to get my switch to boot up around the Nintendo logo now, but that's about it...
Found out a few days ago my prodinfo was ruin (Im not sure if was because I was using HacDiskMount, when trying to downgrade but I dont remember ever touching my prodinfo)
So I've been trying to find a solution to fix it, or at least do a full clean wipe on my switch so I can boot up the damn thing.
Follow the guide exactly how you presented yesterday, but I get the same results.
Probably even worst now... since it doesnt even get stuck on the Nintendo logo screen anymore.
Just a quick glimpse of the logo right before the screen go total dark.

Any help would be appreciated, but at this point... I dont have any hope anymore.

 

Hey, just curious, why do you need a custom exosphere.bin? The way I rebuilt my nand I am able to use normal unmodified OS and normal Atmosphere just fine.

someone I know tried to fix a patched switch with a sx core, but the sx core doesn't allow for tsec keys to be dumped so it wasn't possible to get it working.
