hello is anyone solved this issue? i buy another sd card samsung evo original , also the same...

 

[pcwizard7]

did u start with fresh and let it recreate the Nintendo dir and redownload the game

 

[deawilliams96]

Yes start with fresh sd card , only insert boot.bin for sx pro ... this problem happen because i accidentally paste txt files to sxos/user partition folder with sx installer , then sx installer crash.. i think the user partition corrupt...

i d backup any saves with either checkpoint or JS and reset to factory defaults in the sxos emunand or delete it and recreate the emunand

also if u do, if u want exfat i would create emunand in a hidden partition instead of SD Files to avoid corruption

and would recommend switch to FAT32

no, I don;;t never needed to use it. since your emunand as files my guess your sd card is formatted as exfat which is prone to corruption. which is why i gave the above advice.

 

[deawilliams96]

Thanks , do u have link for tutorial reset to factory with emunand ?

What i did already is :
- original recovery restore failed
- backup with emunand , restore with emunand failed
- create virtual emunand and enable it still failed.

maybe i will try those step again with fat32 format , will let u know later

thanks again

Tried with fat32 new sd card samsung evo original .. still failed . My mistake didnt do backup..

if u are using the same files of your original emunand and just copy them back and forth then that's why once it is corrupt it's still corrupt

i used hecdiskmount , try to mount USER , its asking to format the disk.. is it okay to format ? haha... i will try data recovery tools first..

Harddiskmount, hope your not mounting the switch physical disk as that's the sysnand not emunand

you ignore that and i would avoid just deleting files manually because i did that once and i was soon banned i can't say it was because of that but I would avoid that

to reset it officially hold vol - and + during boot (once you see the switch logo) and its a menu option (recovery mode)

if this doesn't work then ur screw and you have to delete and start from scratch

 

[deawilliams96]

well my switch is already banned.. reset officially also failed...

if i delete/format the eMMC , can i still make this switch works?

just to be clear when you say eMMC you mean the built in memory inside the switch and not the sd card.

if so how are you booting the device

- just power the device with no payload
- using hekate cfw sysnand
- using hekate stock
