I had this happen to me earlier when I updated to the new version of ReiNand...had to delete the firmware.bin and redownload the one from his github, and magically started working.
I recently downgraded from 10.3 to 9.2, and have 10.4 emunand. When I was downgrading, I directly copied all contents on my SD card because I wanted to be able to restore my saves after downgrading. I had Pokemon AS on sysnand as a eshop purchase and after everything was wiped I redownloaded on...
I finally modeled and 3d printed the new HDD cages I need in order to build my 2nd NAS. Original ones don't fit the mounting holes on the hdds I'm using. Been sitting on this project for over 2 years smfh
Also another 70TB going in the front mount drive bays of this server. 182tb raw, going to probably use a zfs RAID-Z3 for 3 parity disks, so 140TB usable
I could claw back 14tb by only doing 2 parity disks but I feel like with 13 disks in the RAID I'd be kind of pushing my luck on rebuild time if I encounter a disk failure
