Blackberry 83 10 failed to refresh, and the phone was frequently disconnected.

Connect BB to the computer, and then watch the timing. After that, if the mobile phone screen can report an error of 507, you can brush the machine.

After erasing, the desktop manager will prompt to disconnect, ignore it, directly open the application loader, enter the program loading interface, select the required program, and the next step is ok!

Hello, if you have any questions, just call me!

By the way, it is best to use the original data cable and USB interface, and the power supply is sufficient!
