Hacking Biskeys...

[Aymenmoham]

Hello everyone
My problem start when I downgrade from 8.0.1 to 4.1.0, I can't boot either cfw or ofw, in reinx it's gives package2 magic invalid,
In hekate read pkg2 failed,

Now I trying to build new nand, I flashed boot0 and boot1, after that in hacmountdisk step in prodinfo its shows fail! Entropy.

Please don't post your keys.
Why did you downgrade? Did you do a backup before you downgraded?

1) Check your keyblobs are intact. Try using Lockpick or my hekate mod to see if you can derive keys. It will probably fail on some, but we need to see if your keyblob data is valid.

2) Next... We need to get rid of any packages from SYSTEM/save. Get rid of all apart from 8000000000000120. If savemeta exists... Delete all apart from the savemeta to the 120 file.

3) Get your "clean" boot0(and boot1) for your desired firmware

4) Flash these cut-down BOOT0/1. They must be 1536kb in size(boot0) and 512kb(boot1). DO NOT FLASH ANY 4096kb size files. This will destroy your keyblobs

5) Boot with Atmosphere (fusee-primary). A full installation of atmosphere(with sigpatches etc)

Good luck.

Do you need keyblobs post 6.2? If they are corrupted can you recover them? If you can't what happens?

They shouldn't be. They will only be destroyed if you have written over them with a full 4096kb

Upload repair main, repair sub. prodinfo and prodinfof somewhere as well as your bis keys... I'll build you a new rawnand

Hypothetically what If I did?

 

[mattytrog]

Your system could not derive the keys... I don`t think its an issue though because it is just PKG2 thats failing.

I`ve had systems booting (with AMS) where the keyblobs were missing. So don`t panic!

keyblobs are not used on 6.2.0+ and are not required for the system to boot. If they get messed up and you need them, it is possible to recover them

The OP is on 4.1.

Very doubtful they are messed up though, unless he has restored a backup from another console.

I think its just a matter of fixing his boot0 and booting with AMS

Sorry @Philliyxx thought you were the OP...

well guess you dont have a nand backup so it will be hard. im really not good at booting the sys but try what mattytrog says.
