My phone is still stuck on "Android is upgrading.. starting apps" on boot.
Earlier, my phone said "Unfortunately, Google Playstore stopped working" and I am unable to use my apps which needed Internet access so I turned off my phone and removed my sd card before doing a factory reset. The reset was successful however it's been booting for several minutes already. I tried removing the battery and putting it back on. I rebooted the device and it is now stuck on "Android is upgrading.. starting apps." I tried removing the battery again and started wiping cache partition, doing factory reset again and rebooting the system but the problem is still the same.
