Got a model 2017 switch from ebay with bsod, already checked usual ICs for shorts, could not find hardware issue. Seller told that the switch suddenly blacked out and did not came alive again.
Switch can access RCM, already dumped the keys with “biskeydump.bin” payload. Currently trying to restore the NAND with this guide gist.githubDOTcom/Karunamon/d3938368c548a61a5a41281bb89f0e49#step-3-blowing-out-the-cobwebs-and-hacks, injecting memloaderv3 via RCM works but fails at executing
umms_emmc.ini with “got 0 bytes, expected xxxxx bytes, error during lzma decompression”. Also if I use the TegraExplorer RCM payload, accessing the emmc info view causes a reset.
Are there any other ways to restore the switch? Thanks in advance!
