I found a solution to my bricked ZTE V9. Nothing seemed to work but what finally helped me was this ===>> http://forum.gsmhosting.com/vbb/f809/zte-v9-optus-too-many-pattern-attempts-done-driver-flasher-firmware-inside-1427615/
I have downloaded the CM10.1 but when i was following the procudure on how to install it, i realized i had formated the sd card which had the rom inside. So i had to remove the battery to remove the sd card and load the rom in it afresh. Unluckily the device went off and now i cannot reboot it is stuck at the ZTE white screen logo. I have ADB which was working perfectly before this happened but now it tells me error device not found. I have killed server and started it again but still the Adb devices command displays nothing. The volume keys once i have entered the recovery mode are also not responding.
