After installing some custom themes(lockscreen?), I can't boot to the main menu in atmosphere

I think i installed a corrupt theme or lockscreen. I removed the program I used for installing it (nxthemes installer latest version) and the themes off of the sd card via my pc but im still having problems. the logos for atmosphere pop up but then it goes to a black backlit screen. Also is there a theme that mimics the layout of the wii u? thanks in advance.

 

ok i can try to avoid it but now I can't boot to atmosphere at all. Is there an easy fix?

 

I deleted that and im still getting a black screen after the nintendo switch logo after going to atmosphere. is there something installed on my nand now that I can't access?

Green Joy-Con D-Pad Shells for Nintendo Switch

 

alright

i see this but don't see a specific atmosphere folder, unless this is ALL the contents of the atmosphere folder?

would readding this (my current version of atmosphere) fix it?

at this point it looks like I need to clear my SD and rehack my switch. bummer. I appriate the help though. If its not booting after replacing the folder then thats not good. ill of course keep my emuMMC folder and firmware folders so i can reupdate
