Ok, because I had a different version on the phone than the version I could find at iprotebe.cz, this what I did to Unbrick the phone:

(Used Service Cable)
Generated the quick_access Patch with qamaker.
Added both Main and FS to the list, ticked the Bypass checkbox, added the quick_access_patch generated by qa_maker on the Misc textbox, and clicked FLASH
had to wait about half an hour.
All done
Added the Unlock vkp , ticked Use QUick Access Patch, cleared both MAIN and FS from the list, unticked B?ypass db2020 ..., clicked Write Script.
This did NOT work at all using the Service Cable, I had to use the DCU11 Cable (USB Cable) for the write script using quick_access memthod to work.

After all that, because of configuration problem, just openes Xs++ and Finalized the phone.

WalkMan is now back to life.

But I still do have the same question: How can I patch_unlock, WITHOUT using the quick_access stuff, no matter how long it takes.

I think that If I add MAIN, add unlock_vkp_script, tick Bypass DB2020... and click on FLASH it Should Work, SIMOX ??
