any pointers appreciated

Here's a complete backup of that same firmware version: https://www.file-medics.com:5001/d/f/480994444600945877

Just be sure you make a backup of everything (modules, tracks, etc.) before you start messing around and you'll be fine.

Thanks @ Jared
i got the loader from hddguru froum thanks to ddrecovery there
https://forum.hddguru.com/viewtopic.php?f=11&t=38282

managed to reach SA , check modules and heads...(have backed up all modules and tracks now )
and here is where i stand

Heads test:- H (0) and H (1) tests bad
h(2) to H (9) are OK

Reading Modules(composite mode):
The following modules are read with errors
6F
2D
12D
189
190

SA structure test gives
Relo list structure error(3) for both copies 0 and 1

will try booting the drive with loader and changing head map in RAM as, suggested by ddrecovery ,

else anything else to try?
thanks again for your effort

If H0 and H1 test as bad, you may as well just plan to replace heads.
