Hi guys
I have this disk ,ST1000LM049-2GH172-LXM3, that came to me with this error:

To enter terminal I have tried many things: play with HM in Rom, short on different boot times, play with options in ROM, loader, etc. No way I can enter terminal or get RDY over ATA because all I get is LED: BD error in the end(BSY on ATA of course). Searching on net for fw backup result in 0 responses. I have managed to temporally get 2 disks with the same fw, LXM3, but without luck, the overlays are build in 2017 compared with the pacient disk that have overlays build in 2018. So the loaders from those 2 donors was useless.

What I need is a LXM3 fw backup, more exactly sys file 20D or mod 3D or a loader with this parameters:
Code:

I think it's all about the timing of shorting the read-channel after handshake.

This one is more stubborn than a monkey.......I tried shorting at different moments of booting but after millions of RECOV servo and Failed servo messages it always sudden go to LED:BD message.
I also manage to extract the overlay from a LXM4 firmware update package, I can get to terminal and get RDY on ATA but, of course, because of overlay incompatibility, I can't do anything in firmware , I have only sector access on ATA. It's good but at first bad sector, and it has a lot, it goes to a pending operation and I can't stop it , except a power ON/OFF. It could be destructive so I want to access fw first to edit hdd ID and after that to start copying data.
