Hacking Question Switch won't boot help

[rogerxiii]

I'm having issues with my (soft)bricked switch. When I first got it I made a rawnand backup, thinking this would be enough, not knowing I needed the boot partitions as well. This was on some early 6 fw, I'm guessing either 6.0.1 or 6.1.0. Now I updated my switch to 9.1.0 and wanting to go back I restored my backup and it won't boot anymore.

I tried following the manual choi upgrade from the homebrew.guide website, but I'm having issues getting my BIS keys to work. Every time I enter them in HacDiskMount I get a red entropy fail error. I've gotten my keys from biskeydump.bin and the sdsetup website using hekate dumps and they both give me the same keys.
I've tried going down to 6.1.0 or even 5.1.0.

Is there anything else I can try to get it to boot? I don't care about what firmware I'll end up on or whether I save any data, I just want it to work.

I have my (seemingly correct) keys from lockpick, including tsec and sbk. I found mattytrog's clean boot images but I'm not sure what to do with them, can I restore my switch using those? Does anyone have some guidelines on what I have to do?

@mattytrog has a "unbrickmyswitch" package. Look for that and follow the directions

Thanks, I found the package on xbins with the "Brief Instructions", but I am still running into the same issue. HacDiskMount simply gives me entropy fail, which means my keys are wrong? I dumped them now with his switchboot.bin but I get the same keys again.

@mattytrog any way you could help out? I can send you whatever you need, I would really appreciate any help on this!

How would my keys have gotten corrupted? When I enter my tsec key and sbk manually on the sdsetup website I get different keys than when I upload the hekate fuses dump or biskeydump. Is this normal?

Note that I tried these keys as well but they also give me entropy fail.

In case anyone has the same issue: using the latest version of lockpick_rcm gave me correct keys. If only that update came a bit sooner, now I have bought a new Switch ...
