    Hey guys, I was trying to go from A9LH to B9S using the 3ds guide and I get a "FIRM backup fail" error when using SafeB9SInstaller. I am using a legitimate sandisk 128 GB sd card formated to fat32. If there is any other information needed then let me know. Thanks.

    Have you checked your sd card with h2testw?

    try backing up all data off the SD Card reformat it with the panasonic SD Formatter (so it formats to FAT32), copy it all back n' try again.

    It worked but I just realized that I can't connect my 3ds to my college's wifi. Am I able to finish the process without updating the console?

    you should be able to but update it when you get a chance, but if reformatting worked, just ment it was going to start corrupting sooner or later. i'd suggest make periodic backups afterwards.

    Set the cluster size to 32K. And format it with guiformat to fat32
