Unbrick ATI Radeon HD6950 (restore bios with atiflash 3.89(!) )?

Question

AMD

Because Searching for answers in Google takes too much time and effort to eliminate too much, I'll try to improve the issue and make it easier for future unbreakers to search :)
Problem:
After a single successful BIOS 6950 flashing (using AtiWinFlash 2.0.1.14) we get a brick that does not want to be flashed back. Utilities used: AtiWinFlash, atiflash, Gigabyte @BIOS (a wrapper over AtiWinFlash, as it turned out).
Suggestions from Google:
If atiflash fails with error 0fl01 (Rom not erased) try to remove the write lock with the command

atiflash -unlockrom 0 (0 is the card number from atiflash -i output )

The advice, in general, is correct but useless, because. the latest, from the currently easily detected versions, atiflash (3.87) will still not cope with the firmware.
Solution:
Use atiflash 3.89 ! Unfortunately, it is not so easy to find it, so I am publishing the link -
atiflash 3.89 ( Rapidshare ).
UPD: Now also on TechPowerUp :)

Answer 1

Unable to write BIOS into bricked 6950? Just use atiflash 3.89, not 3.87 ;)

Why sew at all?
