      If you stock on Avatar logo that not means your device is bricked. Go to recovery and perform wipe cache partition and wipe dalvik cache partition (advance) 5 times and then restart your smartphone through restart now option. If it still can’t help you then you can always flash official firmware to get back your smartphone. As long as you can turn on your smartphone it’s not bricked.
