Hello, i got a problem with my switch. I tried to upgrade the firmware to 6.0.0 using ChoiDujourNX but switch was showing an error after first reboot. I got a full backup of my nand with 4.1.0 firmware so i tried to use it with hekate_ctcaer to reverse the update. So after the backup my switch will not start original os and if i try to boot sx os 1.9 i got a blackscreen. I can still launch first sx os menu and send the payloads to switch from my pc. What can i do to actually use the switch properly?
