Is it before you installed any pirated game?

Hi, my sd card is having some issue so planning to format it and do a clean install. If i restore the previous nand backup that i backed up before any games, then transfer all my files back to the newly formatted card, will i lost my games saves?

Yes, backup your save

Im having trouble to boot to CFW as my emummc hidden partition seems like corrupted. I only able to copy all the files to pc, is there a way to backup the game saves from the files that i copied?

By the way, previously my setup was triple boot (cfw, android ,L4T) it works fine until I downloaded gparted on L4T, then when i open the app, there is a prompt to fix something about the partition. And this happened anyway to fix this?

I don't really have experience with l4t or android on the switch, seem like you mess up your hidden partition sx os emunand.

Thanks for the quick response. Is there a way to backup the game saves from the data that i transferred to the pc since im unable to boot to cfw?

SX OS emunand save data are on the emulated NAND so if you mess that up, the data is probably gone.

I manage to fix this. I check the file system, gparted converted my sd to GPT thats why hekate does not recognise the emummc hidden partition.

My fix:-
On Hekate, go to Tools> Partition SD Card> Fix Hybrid MBR

That’s it. Once converted from GPT back to MBR, everything works like normal

I just got this error an tried everything to fix it. I finally opened it up and discovered that the SD reader board cable was not fully seated. snapped it back in and stuck a new piece of foam on top and everything is working perfectly again.
