Few days ago my phone LED becomes red.
After battery and replace turn on phone vibrates and boots to system (it is visible only under bright light). No possible to unlock etc because of nonresponsive touchscreen. Unfortunatly its stock upgraded 2.3.5 - no root etc. USB Debuging off. No contact thru adb (charging only), but fastboot works.
Phone charges normaly, rings etc. I think it's motherboard failure. I'm quite familiar with hotair and electronics at all.
I googled many solutions but all of them needs root or generaly wipe data.Maybe schematics of DHD will help to diagnose.
I dont need to take phone back to life. It will be enough if touch screen start works with any method (to unlock and usb debug turn on).
Any ideas how to get contacts ? I really need them.
I suspect the phone is working normally so maybe its possible to install some app through play store from PC but it must be unattended setup.
