Hardware Switch does not respond, no RMC!

[eflem21]

Hello,

I accidentally updated to 6.2 and tried to downgrade using my 5.1 nand backup. After restoring my nand I tried to use a fuse-check bypassing bootloader. And here comes the supid part: I used the fusee-secondary.bin file as payload. Since then there is no response from the switch, no rcm, no boot, no maintenance mode. The only thing response I get is when using the dock the green LED goes on and almost immediately turns off.
Has someone got an idea on what to do? Thanks in advance.

I don't have an answer I'm afraid but I'd also be interested in a solution (I recently bought a cheap faulty Switch in the hope that I could get it working but it does the exact same thing as yours - the charging port is fine and it will charge the battery, but the Switch itself is apparently dead, maybe the previous owner was playing around with the firmware and corrupted it).

Maybe you could try RCM instead of RMC
