My s4 will only reboot in download mode. If I do a battery pull and then put the Battery back in, it will automatically turn on in download mode. I've tried with both batteries and same thing.
Only way for me to get around this is to pull the battery, hold button combo for download mode (vol down + power) then reinsert the battery. Once the warning screen comes on, hit cancel, and it will boot normally. But if I go to the menu to reboot, it will only go to download mode and I'll have to do a battery pull again.
No idea why this is happening. It started happening when my Battery was low. So I turned it off to switch out to a new battery. Once the new battery was inserted, it auto started in download mode. Wtf!
I'm running rooted stock. I had twrp installed through goo manager (i think) but never flashed a rom. That was months ago and I never ran into a problem until now.
Any fixes for this? Unfortunately I'm halfway around the world on vacation and won't have access to a computer for awhile. Is my only option using ODIN to flash the stock rom? I hope there's another way around this.... Thanks in advance guys
