Hey guys, My friend brought me a Xtreamer Q mobile phone with broken screen, clockworkmode is working, but USB debugging mode is disabled, I found some posts about how to enable it from adb i tried them and none of them worked.
here :
android - Enable USB debugging through Clockworkmod with adb - Stack Overflow
and from this tutorial i learnt how to edit build.prop file.
Quick guide to modifying build.prop with ADB - ZTE Blade / Libra - Blade.MoDaCo.com - MoDaCo
the commands i have used are: adb pull, adb remount, adb push.
While i was under clockworkmode i mounted system and i pulled build.prop then i added this line to it persist.service.adb.enable=1, used remount then pushed the file after that reboot, but i couldn't find the device in adb when it have booted normaly.
Next i tried to set adb_enabled to 1 in /data/data/com.android.providers.settings/databases/settings.db by following some steps from here
[REF] Disable Wifi On Screen Off - xda-developers.
and it also didn't worked "The device was not listed".
Also i have tried this zip file from clockworkmode it didn't work too...
4.3 jelly bean - Install adb enabled setting from zip - Android Enthusiasts Stack Exchange

My files after editing are attached, wish somebody can help me to enable it.

The phone does not support USB otg cable.
