Hi, my sons S4 went into a reboot loop yesterday. It doesn't seem to be a regular loop though as sometimes it gets to the Samsung Galaxy S4 screen and either freezes or reboots, sometimes it will attempt to start with the Samsung logo, boot music and all, occasionally the screen will start flickering with a grey background, sometimes with vertical lines flashing on the screen.
We managed to get it to boot up a couple of times but it lasted about 2 minutes before it rebooted. I have charged the battery fully, sometimes the phone will freeze on the battery charge screen!
I managed to boot into recovery mode and performed a factory reset which completed the format. The phone will not even begin the setup process, it started once and froze halfway through and rebooted.
I cannot get the device recognised on my laptop using either Kies or Odin. I can get it into download mode but still isn't recognised. It will not boot into recovery mode any more, it just freezes on the logo screen with recovery booting in blue at the top of the screen.
I'm guessing we have nice mobile shaped paperweight!
Oh I have opened up the phone to check the connections due to the flickering screen issue but everything was as it should be.
The phone has just rebooted again and the entire screen has gone grey with black horizontal lines across the top third of the screen!!!
Do I just give up trying??
