Hello! I usually browse in this forum for troubleshooting and it usually works until now, things have gotten so bad I had to create an account.
I'll try to be as specific as possible. my switch (firmware 8.1) had atmosphere custom firmware with hekate 5.2.1 playload, I tried to updrade to firmware 9.2 trough ChoiDujourNX and instead of selecting 9.2(exfat) as I was supposed to I picked 9.2 alone, this corrupted everything and found that the correct fix was to manually downgrade and try upgrading again.
For downgrading manually I followed step by step what this guide said trying to downgrade to firmware 5.1.0:
https://switch.homebrew.guide/usingcfw/manualchoiupgrade.html#step-0-before-starting
I followed every step including backing up my NAND, and the only step where I seemed to find a difference in the tutorial was when transfering boot1 into my switch the size didnt say ''524.29'' but ''524.2'' except from that every step had the expected result until ''Step 13: Launching the First Time After Downgrading'' where the launching didnt work it got stuck in the ATLAX NX logo, after that tried ''Step 14: First Launch Failed'' and didnt work, had the same output , finally tried doing the entire process again and didnt work.
Any pointers on what I could do to fix this? Thanks for your time!
Update: I got this error message when I tried to boot emunand after doing the downgrade ''pkg2 decryption failed''
Then tried restoring my nand to the state prior to the downgrade and get this error when trying to boot emunand '' emummc is forced but not enabled'' , after googling some more people say that I have to get into sysnand and create an emmummc but when I try to launch sysnand I get '' A fatal error occurred when running Atmosphere''
Im kinda stuck. Any pointers on what I could do would be much appreciated
Thanks!
