This intex Aqua Y2 1GB device in hang issue when customer take in my shop then i try first i check shorting in device but there no any shorting in any side, if not shorting in device from all side after check first in software when i try in flash with sp flash tool then device working well my suggestion for everyone who work in android device in software related first check device in hardware after try in flashing because if device short and try in flash then device will be dead or other issue.
This flash file tested by me without any error working well, you can use this flash file when your device hang on logo problem, restarting problem, security lock problem, password lock problem, pattern lock problem etc software related problem and you can use this tutorial without any box and this is free for all who know about software in mobile, impotent for flashing first must check your micro usb cable if not good then you can't flash it so check micro usb cable second check your device battery that is impotent for flashing if your device battery low so stop your device between flash so this is impotent for flash, before you flash save your data like contact, photos, videos etc because this is factory flash file so you can't save after full flash so must remember all are impotent notes.
