The driver that windows xp should look for is update mode, not boot rom, boot rom is what appears when its starts up, but its not the mode you want the phone to be in.

Note: Make sure you have flasher program installed before plugging in phone because the flasher program contains the drivers. Also make sure you hold down "u" key on phone keyboard, not PC keyboard.

1. Shut the phone down completely.
2. Press and hold the "u" key on the keyboard of the phone, not the pc.
3. keep holding down the "u" key while connecting usb cable
4. In winXP the driver prompt should come up, actually two of them will. One is for the boot rom mode, the other is for the Update mode.
5. After XP stops making noises associated with plugging in and unplugging usb devices, then let go of the "u" key on the phone. In total should only really hold u key for like 10secs or so max.
6.Make sure the phone has dark screen and USB logo in top right
7. Go through the windows xp prompts for drivers, one will come up with no driver found just click ok or finish or wtv. The other prompt will find a Nokia BB5 something or another driver, and it will install correctly.
8. all you have to do now is just run the flasher program.

If you need anymore help, let me know.
