And save to directory / folder like C:\KKClient\


Step 2:
After download finished go to directory C:\KKClient\ and run the file: KKClient.exe

The KKClient will create 4 sub-directory like below:
C:\KKClient\ErrorLogs
C:\KKClient\FlashFiles
C:\KKClient\SFL_Files

Step 3:
Download SPL files archives from: (about >110MB)
http://gsminfo.home.pl/_ftp/guar/Data/SFL_Files.zip

And save to C:\KKClient\SFL_Files

After download finished, extract the ZIP file at the same folder.

Step 4:

Turn off the phone, remove battery and put back again but DON'T turn on the phone.

Hold the "C" button on the phone and plug the DCU-60 cable.


Step 6:
If the KKClient status windows says: "Firmware supported for patch unlocking" go to Step 8

BUT... if the KKClient popup the alert says:

Warning! Your EROM version in phone is older than latest version: R3A016
we recommend to update EROM and after flash the phone.
For security reason of your phone flashing is not allowed on old EROM version
We will update your EROM now

you should continue to Step 7


WARNING!!!
If KKClient status window says: "Firmware NOT supported for patch unlocking !!!" you should stop at there copy all the text at the status windows and email to KulanKendi support.

Also... if KKClient says: "Warning!!! CID is not supported" you should DON'T go anywhere, just close KKClient and after a few days, maybe few weeks you can check at:

to see there is a new version release of KKClient (current version is 1.62) that support CID42 unlock.

EDITED by Kulankendi: or look there: http://gsminfo.home.pl/_ftp/guar/Data/SFL
