a920 unlock problem


hi guys
i have a920. i can't unlock with umimoto. i'm using solution for lejiga.
Your problem is caused by ignorance. You have to understand how Motorola phone comunicate with PC via USB bus.

As you may already know, unlock procedure for A Series phone s is diferent than for V or C series.

There are two steps, each of them need separate drivers to be installed.

1. Download unimoto 2.18
2. Power on the phone in normal mode, and wait till windows install "Motorola USB modem"
3. Run unimoto 2.18 and click "install drivers" button, wait till windows install all 5 new devices under motorola part in device manager.
4. Check in device manager if all is ok - if yes, you can start with unlocking.
5. Put phone in bootloader mode (for A920 change to BP bus) and click "unlock"
6. Software will ask you to power on the phone (for A920 it will restart phone automaticaly)
7. You'll see "waiting" then, after windows initialize drivers "witing 4 seconds" then, "connected to phone please wait". If you have all drivers PREINSTALLED corectly, you'll have "unlocked ok" in few seconds.

- Possible problems:
1. You need to use SAME USB port each time for motorola phones. Otherwise, you'll have "motorola USB modem #X " where "X" is number of "modems " installed each time you change USB port. In this case, open Control Panel, Modems, with phone connected, and delete all motorola USB modems from it, in order to install it corectlly.
2. Battery has to be FULLY charged,
3. Brain should be working, at least in "safe mode" -)))))))

I hope this will clear the situation. Do not ask me these questions i have answered here via mail, icq or sonork, i am sorry, but i have no time to teach all customers how to use windows and install drivers.

For unimoto 2.18, and diferent types of drivers, please visit www.unimoto.net and www.unimoto.net/forum

Thanks.

Press the A and B buttons (the two buttons you used to enter test mode) together at the same time and it will change to BP bus mode
