the battery ran out on my Note 3 N9000 then it rebooted with the "downloading" screen and would just stay there for a long time .. pictured .. why/gow did this appear? and would not charge .. going in 1 second cycles .. so i placed another battery botted up .. but seems like all my accounts and some settings were reset .. like i am not logged into facebook .. WhatsApp .. etc ... and it is giving errors .. pictured .. i did not install any new updates .. one thing i can think of WhatsApp update (new with end-to-end encryption) what could it be? why? how? please advise .. thank you ..
