Black Screen after offline update 8.01

[gabrieldantasv]

Hi guys, yesterday I tried to update my switch to last version.

I did this last time without errors, when updated to 6.2

This time I followed some YouTube videos, but without creating a updated backup of nand.

So, when finished the installation, I tried to reboot and then black screen. (That message hold power button 12s error....)

Some people from Facebook group told me that it was just erase the theme folder, that should work.

I deleted my theme folder from sxos, root Sd card.. nothing works.

I have a nand backup but it is outdated so I will avoid restoring nand until I try more solutions.

Can you help me please ?
I can’t boot on CFW but if I hold + vol I can enter the sxos menu and boot OFW.

Did you delete the theme title folder in sxos/titles/

How did you update to 8.0.1?
If you used Choi, what is your SD formatted and if it is exFAT did you select exFAT in Choi?

Something happened with the update to 8.x then. Possible bad update files.

7.0.1 didn't work as well until 2.7.1 beta upgrade

7.x needs SX 2.6 or higher. 8.x needs SX 2.7 or higher. I didn't see in your post what version of SX you were using prior.
