Debranding k800 with A1 Java Unlocker

Hi. I`m trying to unlock/debrand my phone using this program but so far I cannot seem to get it done. I cannot start at all.

The "ready" button doesn`t appear...

The USB Flash drivers seem to be installed, I`m connecting the phone (without a SIM card, or memory stick) holding C, selecting the firmware.... And still no "ready" button.

Maybe the problem is that the program asks for the firmware to be an *.a1sw and *.a1fs file extension. As you can see in the picture the firmware (and the other firmwares that I found on the web) have file extensions .mbn and .fbn .

If these are not the right firmwares to flash my phone can somebody please tell me where can I find them, because I cannot seem to google any .a1fs or .a1sw files.

Maybe my flash drivers are not installed right. How can I check if they are properly installed?

Please help.

p.s. my main firmware is R1KG001 with CID53
p.p.s. maybe you can recommend another way of debranding my phone. Any help would be great. Thanks...

Well, I have also find out that I need a hardware tool for this method and program so... I guess I`ll try something else. I also don`t have the original SIM anymore so... That may be a problem.

Right now I`m looking for a way to unlock it without that SIM. Any suggestions?

Thank you for your help and links.
