Black screen blue light.

[Android Central Question]

I have a Samsung galaxy s5. Sealed battery.

My blue led light is flashing but I have an unresponsive black screen.

I have held power and volume down button. And tried volume up, power, and home.

Neither are working. Is it worth keep trying? Any other suggestions?

I have worked for AT&T for 10 years, so I have seen this a few times.

Blue LED flashing with no screen means the bootloader on the firmware is shot. I would recommend you try to use Samsung Kies or SmartSwitch to try to reload the firmware. If you know someone more nerdy, they may be able to get the firmware and use ADB to force it.

When I was working, I referred people to the Samsung store-within-a-store at Best Buy for this, but Samsung has pulled out of our local BBY.
