Black screen 2.9.2 & 9.0.1

[Mariojm]

Haven't played for months on my Switch so I updated SX OS version to 2.9.2, restarted and then i couldn't load the cfw, the dongle acts like normally but i get a black screen and I can't acces SX OS menu.

I updated to 9.0.1 and the error is still happening.

Download again the latest SX OS beta file, format your MicroSD card, make sure your console has at least 50% of battery, else let it charge for at least 30 mins. When ready, hold the "+" button while pressing the power button on your console. Keep holding "+" until you see the SX OS logo. From there just choose your option.
