I have an LG 4X HD that I usually connect to the pc via usb. I have Windows 8.1. Till yesterday, when I connected it via usb, the phone always asked me the type of USB connection (only charges, media sync, tethering usb, software lg, photocamera (ptp)). I usually selected media sync. On the pc, it appeared a new storage device (I could always browse it).
Now suddenly it has stopped to work. The phone only start charging, but don't ask me anymore what type of USB connection I want and on the pc no new storage icon appears, so I cannot browse it anymore. I used to work with this phone, that is, installing my app
.apk via Eclipse (i am an android developer).
I have tried a lot of things (reinstalling usb drivers from the LG website, reinstalling LGMobile Support Tool and so on) but nothing seems to work. I have tried to install the Universal ADB Driver setup, but it doesn't work neither.
What should I do? Is the problem on my PC, my phone or both?
I have already tried to use a different usb port/cable without success. I have another android phone, an LG P690 (a bit older), and it is working both as storage and as a device to which i can install apk from Eclipse (or Android Studio, which is another development IDE). The problem is still there for the P880 (LG 4X HD) which, as i already said, suddenly was not recognized anymore. I have noted that, when i plug the P690 phone, on the 'device manager' screen appears an item 'Android device', under which there is the 'Android Platform Sooner Single ADB Interface' driver. On the contrary, when i plug the P880, nothing happens (but the phone start charging, so the usb connection should be ok).
