I accidentally updated to 6.2
Then I downgraded to 5.1
And deleted every thing by mistake
My switch won’t load any thing at all not cfw not ofw nothing only black screen
I have no backups
I put the SD card and get no files on it
All my files are gone
No nand backup or EmuNAND backup

I know It might be over for my console but is there any chance
Any tips what to do
Please somebody help me
Thanks
