I am really stuck with my blackberry 8900. I read almost all the thread about stopping constant reboot cycle and done everything, but it still doesn't work. When I connect the device with the battery pulled out, as long as the red light is on, apploader says USB-PIN: UNKNOWN. But after completing reboot, a black screen with a crossed out battery sign shows up and the pin is shown by the apploader. If I click next, then it says, "Connecting to the device ARM", but after a while it says "Unable to connect to device".
And with battery it says USB-PIN: UNKNOWN. But after clicking next it shows the same error message. And the device does not reboot again. No red light, no screen.
Can please someone help me? Is my device is totally unusable? Is it a hardware problem or software? Or am I doing something wrong?
