So say someone successfully unbricks 9 cameras using this method, but in the process irretrievably loses the mtd files for one. Is there any hope for recovery? Asking for a friend.
The good news is that the camera took the 5.2.5 firmware and is reliably stuck in min system mode, so I can telnet to it. I tried modifying the mtd6 from another camera (similar, but not identical.. the one which remains bricked is a DS-2CD2132F-IS, and the MTD I had was from a DS-2CD2132F-IWS. (In that MTD I edited a byte of the mac address to make it unique, and appropriately altered the checksum - I also simply tried to edit the ASCII portion of the name to remove the W and moved the S back to the previous byte)
I may have a DS-2CD2132F-IS installed and in service. If that is the case is there an easy way to pull the mtd's off that (If I have one, I can't be sure it's from the same batch or same vendor given how long ago I procured them? I'm also sure I have a USB to TTL serial cable somewhere if that provides alternate paths to recovery.
