I wanted to flash my auxus 5.5 and before that I wanted to take a backup. I booted into recovery and tried to take user backup it was running whole night but not finished. I removed the battery and switched on phone and it was working. Later I thought there may be some problem for removing battery during backup and made a factory reset. From then onwards my usb is not connecting to computer. No usb pop up. No otg, no mass storage, no media device, nothing. Then I thought flashing may resolve the problem. Installed drivers successfully. And flashed without any error message. But still the problem is not resolved.. Please tell me where I'm wrong or is there any patch needed to install to get usb work. My phone is still connecting in flashing mode so I think there may not be any hardware issue. Please help me to get out of this problem my friend. I have mountainous hope on u.
