[Black_wizz]

Hi all

I was trying to uodate my CFW using choidujournx and i successfully did that and boot into it then i get crash

After that i get blue screen and i cant boot CFW or OFW

I have dump my keys and try hactool and choidujourn using pc i cant get the correct key

I can boot sc os or haket and i try to boot atmosphere but i get error before its start i get error faild to decrypt pakge 2 rivison 7

I dont have previous OFW back up i cant find it on my computer

So i believe i need to build clean nand backup and in order to do that i need the keey from boot0 i just dont know the correct way to do it every key i get and use like lockbin key or hacket or biskey it dont work


anyone face similar issue or can help ?

You can use biskeydump to get your TSEC & SBK Keys or Hekate to dump your fuses.bin & tsec_keys.bin.

After dumping your Files/Keys you can use this Site to derive your BIS Keys.

If everything Fails you can use this Guide to recover your Switch
