Question about AT&T Blackberry Curve 8300 Smartphone
I HAVE A BLACKBERRY CURVE 8310 I TRIED TO UNLOCK PHONE USING MFI THE CONNECTION FAILED. NOW THE SCREEN IS JUST BLANK AND THE RED LIGHT IS JUST FLASHING. I'M CHARGING IT NOW, BUT I AM TOTALLY LOST. REALLY NEED HELP
Follow these steps
When your device fails to start, it show one of these symptoms:
1. Totally dead.
2. Trying to restart, LED activity only.
3. Failed to start, a white screen with an error message.
1. Physical damage, water is the worst enemy of delicate electronic device. Try drying it with a desiccant and replacing the battery. If there is no activity, you can still try the last ditch technique, nothing to loose anyway.
2. Your device is not able to start, something has gone wrong and the OS is corrupt.
3. Geeks call this an "Uncaught exception error". That is a polite way of saying, the last thread has terminated, the OS has halted because it is corrupt.
In many cases, the Application Loader can be used from Desktop Manager or Windows.
If that fails to connect, there is one final solution. Go Old Skool ...
The good news, starting from scratch, you will be back in service in a couple of hours.
Note: Windows 7 beta is not compatible with these instructions.
2. You need to install a BlackBerry OS file that is specific to your device. The original version, as supplied by the carrier, is the safe choice, but you can use any model specific version.
3. Once the OS has been installed, you have to prepare it for the device.
Select Start / Computer and select the Drive C: Icon.
Open Program Files / Common Files / Research in Motion / AppLoader.
Navigate to the bottom and delete the file Vendor.XML file.
4. You are now ready to restore your device. Verify that BlackBerry Desktop Manager is NOT running. Plug the device directly into the computer's USB port.
We are about to venture into the bowls of the beast. Windows is not suitable for this job, we are going to invoke the Command line interface with an option switch. This was the way all 'computers worked prior to Mcintosh and Windows.
Windows XP: Start / Run... / Command
Windows Vista: Start / Command (type this into 'start search')
