I flashed PureXperia z2 v4.2 on my Fly IQ446/Xolo Q800 and I cleared the cache and dalvik cache. After rebooting, my phone is stuck at the bootscreen showing PureXperia z2. I've redone this procedure quite several times but the problem persists. The OS does not boot at all even after waiting a whole night. Please help me figure out the solution. I'd be grateful if anyone could help me resolve my problem.
