Here is a method I found on the web, not sure if it works...
LOTS MEMBERS...FLASH WITHOUT NOWING THE FW..VERSION...AND SET GET LOCKED.. SUBSCIDARY CODE,P2K AND PDA GROUP..IDECIDED TO MAKE SMALL TUTERAL..TO MAKE THIS CLEAR
1) Download SBF RECALC
http://www.4shared.com/file/12999005...ecalc_128.html
2.Create a folder and put your locked flashfile into it.
3) Open SBF RECALC.
4) Click on "Open Flash-file" and select the one you want to unlock.
5) Click on "Split Flash-file".
6) Click on Open CG-Folder and select the folder that contains the splitted firmware (it is the same one).
7) In "Advanced" tab, make sure that "Remove Ask for Lock" is checked
Click on "Recalc Checksum". When it finishes there will be a message like: "n Sim- or Netlock found and removed".
9) Click on "Create SBF-File". Now the unlocked firmware is in "SBF-FlashFile" subfolder. Flash it.
NOTE: Should SBF Recalc say when clicking on "Recalc Checksum": "n Sim- or Netlock, already unlocked", then the firmware is already unlocked.
