Hacking Since nothing helped until now

[DustBite]

Hi Guys! The Situation is like this:

Started switch, accidently pushed yes to update since it was in WLAN. Without further asking, I got 12.0 FW back.
Me just downgraded via Daybreak to 11.0, after that, my main mSD wasnt able to boot to sxos anymore nor could I use it for anything since Bootscreen said,
please use mSD with fat32 and not exFAT. Ok got a new mSD with 32gb. Thought, to get exFAT back, maybe downgrade to 6.2 and get back up to 11.0 with exFAT support.
Well, now after downgrade, I'm not able to get behind the SWITCH BOOTLOGO. I can go in RCM but even there, I get always stucked after SWITCH BOOTLOGO.

Did everything the guides said, but nothing seem to work. I still am able to get in RCM, but doesnt matter what payload I use, I get stuck at the nintendo switch boot logo.
Got my old NANDBACKUP, but it seems like its too big to be transferred to my 32gb FAT32 mSD. Tried it with hjsplit, still no success.

Meanwhile I'm still able to boot SX OS payload, where I can enable auto rcm and stuff like that, but nowhere getting near to starting homebres or something like that.

Any sugesstions what I should do? Working on it since Saturday, eyes are bleeding x)

Regards.


EDIT:

When trying with Chojiuduro, I get stuck at some Errormessage. Would be fricking awesome if some1 can help in anyway possible x)

You could just format the card as FAT32 when it asks you to "please use mSD with fat32 and not exFAT".

 

[DustBite]

Weeeeeeeell its that far in trying that this question isnt coming anymore plus I didnt wanted to loose safegames / data

 

[Hayato213]

You shouldn't have downgrade, downgrading made your situation worse, when you could just use a FAT32 SD card. What is your fuse count?

 

[DustBite]

I think its 6, yea I was just stupid.

 

[Hayato213]

Got NAND backup?

 

[DustBite]

Yup, its extreme old, plus its too big to put it on my 32gb fat32 card

 

[Hayato213]

Well it depends on the fuse count on the switch and the fuse count version for the firmware that backup is on. You can use the tool below to take a look

Hmm, all I can see is the FW from the backup is 7.0.1, whats the use of this info?

base on anti downgrade table of fusee count if firmware is 7.0.1 expected fuse is 9 if your boot0/boot1 and rawnand is from firmware below your fuse count you can probably get it to boot.

 

[DustBite]

Ok, how do I do that ?

Check your fuse count in Hekate, compare it to the anti downgrade list.

[DustBite]

ffs, hekate now says burnt fuses 15/64

Then even with your NAND backup it probably won't even boot you can backup your current broken NAND and try this

Could you not format the mSD as exfat, transfer your NAND backup to it, and use hekate to restore the NAND? Then you should be able to boot using atmosphere

Nah, not working since it needs to be fat32 :/

 

[eskinner3742]

could you not

I don't think it matters with hekate, only when you boot into HOS. You can always format it back to fat32 after the NAND is restored

 

[DustBite]

Sure, already tested. It matters since it says y u try to restore from exFAT and not fat32, but my nand backup is a one file and bigger than 29gb as mentioned above splitting and stuff like that didnt work with hjsplit

Mind telling me how to use this? Would be great xD

 

[Dust2dust]

Your big 29GB NAND backup should be named rawnand.bin. Have HJSplit split in files of exactly 2,147,483,648 bytes (last one will be smaller, of course). This is the size Hekate uses for FAT32 SD cards. The files should be named rawnand.bin.00, rawnand.bin.01, rawnand.bin.02, etc. You should also have two small files, named BOOT0 and BOOT1. Put everything in the restore folder, and Hekate should allow you to restore your backup.

That I have no idea how to use, never done it as I always do NAND backup, I meant why don't you get a 64GB card and try your NAND backup first.
