I'm trying to unlock, debrand and customize an old K800i that I've came across. The problem I'm running into across different programs is that though the PC is picking up the k800i (and subsequently installed it) programs like XS++, GFlash and SETool Lite will not pick up the phone. Error message I'm getting in XS++ is

15:02:09| Error: Cannot open phone communication port
15:02:11| Disconnected... Unplug the phone

GFlash tells me it can't open a port
SETool dosent pick the phone up

Followed the instructions to the letter (power off, hold C and plug in) but no joy. Help?!

i think you have 2 install USB Flash device on your pc .

Correct

Hi, is this what you are referring to?

Sadly, no, but at least you tried searching

EDIT: see next reply for my link

Hi thanks, I downloaded and extracted, right click-installed the drivers but still the same issue

EDIT, latest USB flash drivers: http://www.wotanserver.com/USBFlashDriver.exe

Right click my computer, select properties. Now go to the hardware tab and open device manager

Take sim out, take memory card out, and reinsert the battery, do not turn on, do not open anything else on the pc (including XS++)

Connect your phone to the USB cable holding 'c'

See if windows detects a sony ericsson USB flash device (watch the USB ports via connection if possible ie view devices by connection)

If it dont, and shows new hardware found or a new device with a question mark beside it, right click on the new hardware, and select update driver, and use the driver thats above. Say continue installion at the poopup window, then youre ready

Hey thanks, worked like a charm. Before I crack on with unlocking it, am I right in assuming I should SET Tool and just press unlock and thats it? Or is there additonal steps I need to take?

If you do that, you'll might brick the phone! http://forums.se-nse.net/index.php?showtopic=20668
