If you mean translator regeneration, i already send m0,6,3,,,,,22 after sys backup, but it didn't help.

I meant that terminal shows you what's wrong. Most of cases it's translator issue but can be caused by few things. Did you check NRG, SMART etc?
I don't use MRT and don't know why the patch doesn't work. Is the ROM read without any errors? Maybe there's somenthing about this error on their forum/site/support.

in terminal it let me access into p-list by sending V10 command (i didn't post here because it is very long).
Most of P-list has "80" flag, but i think it has some issues due to some other flags included as "8" - "10" - "C"

You can find the entire terminal log inside the rar file that i've uploaded on mediafire

I used F3romExplorer 1.0.9 to check the rom, it hasn't find any flipped byte. It says all OK
About MRT, i've contacted tech support, probably they will answer me in the middle of the night... i'm located in italy, they are in china.
I've use already the virtualboot function for other cases, it worked well for those, but for this case is not working. :?

Yes but not in ATA mode, i edited via terminal only after i saw that wasn't possible to get access via virtualboot by sending this:

Code:
F3 T>
ASCII Diag mode

F3 T>F"RWRecoveryFlags",00,22

(D) SATA Reset
Byte:00A2:       RWRecoveryFlags = 00

F3 T>F"BGMSFlags",00,22

(D) SATA Reset
Byte:011C:       BGMSFlags = 00

F3 T>F"PerformanceFlags",043C,22

(D) SATA Reset
Byte:057C:       PerformanceFlags = 04 3C

F3 T>F"MediaCacheControl",00,22

Invalid Diag Cmd Parameter

Try to write from another or an empty sector.

If the error remains after rewriting, the recording heads are bad.

I've already provided the solution, i just repaired the damaged SYS.
I repaired SYS 301 copy 0 by overwriting it from copy 1.
SYS 319 is the biggest SYS, but i didn't overwrite it. I only tried to read it from copy 0 (the good one) for the purpose of backing it up (it took a long time in serial mode). After that, i tried to access SYS 319 copy 1 (which was previously damaged because it returned an error while reading), but this time it had no problems opening, so i didn't touch it.

After that, i sent the translator regeneration command m0,6,3,,,,,22 again, which this time took effect. I had already tried sending the command before i was able to understand that there were corrupt SYS, from the response log on the terminal it appeared that the m0 command had completed successfully but in reality it had no effect, the disk remained in busy.
