reboot loop

[rymac14]

Hi, my phone has been stuck in a reboot loop .It reboots every 20 seconds or so, shows the sony logo, the andriod screen and then starts with blue "waves" welcome screen , then restarts. it doesnt remain functional enough to use the pc companion - as it reboots so frequently the software cant detect.

i've tried hard turn off (volume up and power, as well as the button under the sim card slot, loading with the sim and sd cards in and out and every combo. 

any advice? pulling my hair out...

Hi rymac14,

Welcome to the community,

Can you advise what happens when you hold the power button and volume + key for around thirty seconds, is the device vibrating three times and if so does it simply start the loop again?

Hi Jake - me, but on another account.

Yes, it vibrates 3 times and turns "off" . when i turn on , it goes back into the loop.
