so something odd happened
i've made no system changes in the last week... all i did today was install Freedom app and used it on a game.
so i played (wheres my water 2) for about 2 hours and my phone got hot, so i decided to reboot it and then let it cool
but then it failed to boot, it showed "Google" and shut down, and again and again.
so i held the volume rockers and went into the bootloader mode thing, chose reboot, and this time it boot went all the way to the 4 colors screen, and again reboot (over and over)
then i went to the TWRP screen, was about to wipe cache but was not sure if i go to advanced wipe and only mark cache and delvik if it will still factory reset or only wipe those, so i just reboot and this time it worked.
following reboot attempts do work.
any idea/way to check what i did to mess things up/fix it?
