    Hi all,

    I really appreciate some help to get my Switch (if possible) back up and running. After trying to play Animal Crossing (with SX OS) the Switch crashed and after every boot (CFW of OFW) I see error 2002-4686. The error appear after the Nintendo and Switch logo's during startup. My guess is somehow that the user filesystem on the Switch got corrupted (I saw some other articles about key mismatch). Unfortunately I don't have a backup to get back to a previous state :sad:.

    I made a dump of the keys and a complete NAND dump from the Switch so I can open it with 'HacDiskMount'. I can mount the NAND dump, but I have no clue what the BIS Key 3 are from the Key dump to take a look inside the USER folder with HacDiskMount. So I'm getting a little bit stuck at the moment to get any further. Does any of you guys have more experience to deal with this problem? I would really appreciate to make use of your experience :)

    Thanks in advance for your reactions.

    Kind regards!

    iirc BIS Key 3 is the same as BIS Key 2.

    Try another micro sd card or reformat.

    Thanks for your response. Not sure if the sd card is the bottleneck, because I see the error both in OFW and CFW.

    Use Lockpick_RCM to get text readable output with keys

    I already did, I have the readable output file. But it is a huge list of keys :D. Not sure which are the correct ones.

    I got some little further and indeed as masagrator mentioned, the BISKEY 2 and 3 are the same. But when I try to save the biskeys on the USER partition, I see the following error in HacDiskMount:

    So I,m a little bit stuck here right now :(

    Is there any way to fix this, or is the switch definitely bricked?
