Hacking error on modded switch

[mister2456]

hello
I am new to switch modding and just modded my switch
At first it worked but i was on version 21.00.00 so i looked into downgrading firmware and found you could with daybreak
So i went trough the process but now every time i try to open emummc cfw i get this error after is shows the atmosphere logo and the switch logo loads for a bit and then boom i get this crash every time
Does anyone know anyway to fix it or has anyone got an idea i have tried a lot of things but nothing worked please help

Did you perhaps blank your PRODINFO serial numbers?
That is no longer allowed with Atmosphere.

If not, check for a folder 0100000000025 in /atmosphere/contents and try renaming it to 0100000000025.old or something.

When you used Daybreak, did you choose to preserve the data or did you perform a factory reset?

When downgrading, it is mandatory to perform a factory reset, otherwise it will not start.

i am pretty sure i didn't factory reset
what do i do now ?

reboot by keeping vol- and + pressed and do factory reset from there

i have the same issue, but now after factory resetting it asks for resetting the sd card too. how can i skip this?

I did it recently.
It's true that it asks you to delete the contents of the SD card after resetting, but all it does is delete the “Nintendo” folder. In fact, if you read the warning, it says that it doesn't touch anything else.
I recommend making a backup, just in case.

Need to know the Atmosphere' crash screen program ID to know what causing your crash.
