Hello! So I had a switch running on SX OS 2.8 and decided to update the firmware to 9.0.1 since some games weren't running suddenly. I used choi to update, but after the reboot, the switch would not boot up. Someone mentioned that 2.8 didn't support that firmware so I put the latest SX OS boot.dat in my sd card and it still won't boot. Please help, did I fuck up and break my switch or is there anything else I could do? EDIT: I also did a NAND backup but since the switch won't start up is it possible to restore the NAND?
