switch can’t boot to HOS, it can boot to hecate and accepts payloads, though it hangs on atmosphere logo if you try to launch it. autorcm is disabled so it should boot to OFW but only blackscreen. a week ago it was booting up normally. fuse count matches. emmc module looks good. no shorted component cap on emmc module.
- was able to do a full nand backup( boot0/01)
- dumped valid prod keys.
- can enter rcm using jig
my guess is this is hardware issue, but no idea where to look first.
