Selecting to upgrade the firmware said “downloading' until the phone battery died (was on 90% to start with) and didn't fix the issue.Ĥ) Powered up with Volume Up, Home, Power. It brought up the Firmware upgrade boot screen, but just rebooting off here didn't work. I have no SD card.ģ) Powered up with Volume Down, Home, Power.

I swapped the battery over and then this started when I turned on again. The problem started when the phone ran out of charge and powered down. It had just performed a software update which had completed successfully, and phone had rebooted. I've tried three different batteries, two of which are genuine Samsung ones, all of which worked fine until the day the S5 started boot-looping, so I'm disinclined to believe it's a battery issue with all three batteries.
