Hey guys I got a very strange problem.
I successully updated my a9+ to jelly bean, which worked for 3 days. Suddenly while charging my phone, it died. I saw the phone charge upto 93% and when checked later it was turned off. I tried to turn on the phone, fastloader and qpst download entry mode... nothing worked... I thought that there was some hardware malfunction..
Then I tried connecting the dead phone to PC and a device under Qualcomm HS-USB QD Loader 9008 got installed. I search google and came to know about tutorial where you could flash bootloader thorough QPST (Qualcomm Product Support Tool). I followed the tutorial but i received error "Cookie not available", which according to tutorial is not solvable.
I don't know the cause of this problem... Maybe it was eMMC internal flash failure without any fault on JB update... Or something that happened due to jelly bean update process and incompatiblity of the firmware with a9+..
Now my question is:
1. Is my phone eMMC flash damaged physically beyond any repair?
2. Or the service center guys can still access my eMMC flash and repair it?
3. If eMMC is damaged, can it be replaced or the entire board needs to be replace?
