Hacking Discussion Upgraded to 8.1.0 then downgraded back to 4.1.0 (originally on) gives Atmosphere error 2002-4315

[lovebirdlover]

New switch, got a clean NAND with BOOT0/1. I updated with Choi to 8.1.0 and realized i should just update officially then put my switch offline. So i downgraded back to 4.1.0. When updating, i chose support for SDXC then when downgrading back to 4.1.0, i didnt choose support for SDXC since it didnt have it and kept nagging me to update to support it.

After downgrading, Atmosphere keeps booting and gives me error code 2002-4315 and i really hope i didnt eff up my system. I just want to get back to the homescreen, update officially to 8.1.0 and be good. Please help!

edit: want to add it always boots to rcm and fuses are still my original 5 out the box

Title 010000000000000C is bcat according to switchbrew.
And checking 2002-4315 on Atmo-Discord is saying the save data is corrupt.

By chance did you re-initialize the system like choiNX recommends when you downgraded?
(That's all I can really think of where you may have gone wrong, someone else chime in if this issue is familiar)

When not downgrading via Hekate and an old Nand backup, it's recommended to do a system re-initialization with this button in ChoiNX.

The obvious downside being that it's a factory reset that wipes all saves and titles from memory.

If you have good Nand + Boot0/1 (firmware specific!) to restore to then yes I'd recommend you restore to that.
Though you'll likely lose some saves or tickets made/installed after the backup was made.

If I am downgrading on an EmuMMC, does choosing the System Initialize option only affect the EmuMMC, or does it affect the eMMC as well?
