Switch can't boot sx os/ofw - unknown reason

[Pitbull]

Hello, a have some problem with my switch before that everything was okey a turned off switch and plug sd card to pc.

I did three things on the sd card:

1. I copy nand backup to pc and delete from sd card
2. copy hbg shop installer to sd card,
3. delete one game

After that back sd card to my switch and... nothing. I can't turn on recovery mode with sx os dongle with jig of course and can't boot ofw too. When a plug switch to charging dock the light is flash (turn on and off - 1 second).

Boot with SX OS 2.8 Beta/8.1.0 software version and enable autoRCM on switch.

Do you have some ideas?

do you still have Boot.dat file on the root of your SD card ? ( boot.dat= SX os)

test if your NS is not in RCM., go ahead ad Plug your switch to your PC and run TegraRCMGIU and see if it detects your Switch, if it does try injecting the payload that way at least to get it out of black screen
