I've changed my SD card to 32GB and formatted it with Windows 10 to Fat32 with 32kb cluster size. When I launch EmuNAND9 it sometimes doesn't work (I just got a black screen), and when it does work when I try to create a sysNAND backup it stops working at the beginning of creating this file and throws an error: "NAND or SD i/o failure Backup sysNAND to file: failed! Press B to return, START to reboot." Or it does work but it throws the same error around 20-30%. Is it normal? I've tried to do this backup many times and I'm just stopped by this random error. What should I do now? I'm following this guide for installing A9LH: https://github.com/Plailect/Guide/wiki/Part-2-(9.2.0-Downgrade) And I'm on step 24.
