Computer do not connect with OB - so I can't restore stock rom! (USB problem?)
(First, sorry for my bad english...)
I have a really big problem. My brother's OB has CM7 custom rom, with CWM recovery, so it lost it's warranty. The phone has got some hardware problem, like "silent" speaker at calling, can't connect to computer via usb and the turn on/off button has got hectic working.
Also, my problem:
- when I connect it to any computer at home, to restore the stock rom, I push the volume+ button, and it goes to flashmode, but the computer do not anything with the phone. The drivers are installed, and everything is done, wich is written by the "how-to". Some months earlier, I restored it, and this phone was in service, so I know what I do, but I think it's a hardware problem.
Sometimes the computer recognizes the device as "unkown device".
Has anyone an idea, how to solve my problem? Were there a method to flash V20O via zip file, than remove the recovery without computer?
Thanks for your help,
