I tried following this tutorial, but at ChoiDujour when I try to use cmd line to convert my downloaded firmware with my keys.txt (from lockpick RCM used on sysnand), it just fails. It just says failed to execute script and also a bunch of warnings saying failed to match key. What should I do to unbrick my switch? I'm super lost at this point.
How I got into this mess:
I used SX OS with the dongle that came with the SX pro purchase. It worked for a while. I recently wanted to update firmware offline with ChoiDujourNX. I download 9.2.0 firmware and try to update. After the update, I can get into RCM and choose launch CFW, but I get a blackscreen with nothing. When I repeating with running original firmware, I get a blue screen. I tried a nand restore, but my backup seems to be bad since I can successfully restore boot00 and boot01, but the rawnand restore ends in errcode:00fffd47. I was able to inject the lockpick payload to get prod.key file which I later renamed to keys.txt, but that didn't work for the tutorial in this thread (as described above).
I would really appreciate any guidance and help with this.
I wanted to look for the unbrick pack on mattytrog's git, but I couldn't find his git either. I'd also appreciate if anyone can get me in touch with him or point me to this unbrick pack?
