Hacking One more brick.. I need help!

[RuqeT]

Hello!

I accidently did Update my switch to the newest Firmware. I Was using SX OS before and after the Update SX OS didnt work anymore. So i decided to restore a Backup from an older Firmware. After this my switch dont Boot anymore, i just See the Nintendo Logo and then a Black screen.

I dont know which Firmware Version the Backup had. I think maybe the fuse count dont Match?

I tried some tutorials for Update the switch Firmware With my PC but i cant get the "Keys.txt". I always get error Codes or for example of i usw lockpick RCM the switch just shuts down when i try to read the Keys..

Can someone help me? Sorry for my Bad english.

Does the Switch boot using Hekate or fusee-primary?

 

[RuqeT]

Yes boots with hekate, but only into RCM. I try the pickafix tutorial now and report back.

I mean, can you boot the system successfully using Hekate or fusee-primary (with Atmosphere on the SD card)?

If it was an issue with just the fuse count, these things would bypass it.

No i cant boot the system with hecate.. i did try to restore the nand with pikafix and unbrick_your_switch package, i always fail with dumping BIS Keys. biskeydump tells me "ERROR deriving device keydata". If i use the keys that https://www.sdsetup.com/biskeygen gives me i cant mount the SYSTEM/SAFE/USER drives because it tells me wrong BIS KEYS.

if you use old fw backup, that means you need rcm to skip efuse check. So if you use to payload and turn on your console as cfw (sx os or atmosphere) you will probably turn on your console. You should be sure your nand suport exfat or fat32 so your sd card must be on correct format.
Also you said you did backup but you should backup boot0 and boot1 files too. Otherwise you will get an error.
i hope i can help for your problem and sorry for my bad english

UPDATE:

i tryied to rebuild a new rawnand bit mattydogs tutorial but it always fails with hacdiskmount. It always says "FAIL! Entropy...." and i cant mount the drives. It seems like i get wrong BIS keys?

You should use ChoiDujour instead.
