I have got a used BB9000. It looks the same as mine (vodafone), and it is not simlocked. However it boots up with an AT&T "world phone" logo.
Using the same procedure as with my own, I tried to upgrade the firmware to v5.0.xxx.
does not work. It comes up with the message that no suitable software was found for this device. The device was used in Germany using a SIM from vodafone.
To check if I made something wrong, I used my own BB 9000. Immediately the device was reconized as ready for an upgrade.
Is this a special Edition which is locked to AT&T firmware, or, is there trick I can do to circumvent this limitation ?
