Switch facing weird emmc corrupt data issue

[RyanTheArchivist]

Slow boot time has to do with the A1 card, as for your game crashing it is probably have to do with sigpatches/syspatches.

Afaik the Switch's slot doesnt really even take advantage of A2 speeds.

Well if the emunand wasn't working then it is obvious no point using that as a backup, I mean it is bad that you don't keep a NAND backup, I guess your last resort is EmmcHaccGen

I have like 10 different backups i just dont know which one of them is the original one but still how can it help me if it. was bricked then.

Well you just going have to go through them see which one actually work. If all then doesn't work then your other option is rebuild nand.

A2 speed card boot faster and faster when doing a NAND backup.

yeah an a2 card just unlocks the sd card reader and enables it to read and write at faster speeds than it's rated for

Hi there.
I face the issues of inconsistent booting to atmo and games crashing most of the time but HOS on its on works fine. I narrowed my search to data on emmc as replacing it didnt change anything and i confirmed that everything else including ram and sd card works fine. Systemrestore is not helping here so the issue is somewhere deeper. Now do you guys know of any tools or ways to completly restore all data on emmc to how it came originally? Dont ask about hardware as its working fine.

Remind us, are you trying to use AMS with the sysnand or emunand? Does OFW have any issues or just AMS?

i tried using both but they yield same results and OFW on its own works fine but crushes when booting games

If memory serves you rebuilt the NAND meaning you can't go online to get a game, are you testing with a cartridge in OFW? Are we talking an HOS crash or a software closed crash?

i got it on the internet and i testested 2 cartridge games and one digital no difference. And tested in OFW only

What kind of crash? Does it just close the game or does it truly crash HOS? You must have had valid prodinfo backup if you can sign into NSO.
