Galaxy S4 stuck in reboot loop

[razhas]

Hi, I have a galaxy S4 which I wanted to upgrade to Lollipop, once the install was complete the phone rebooted itself and it is now stuck at booting loop. I have booted in safe mode and the same thing happens in safe mode.

I am happy to do a factory reset but I haven't saved my data, how can I save my date when the phone doesn't even stay powered on? Or how can I fix it not to boot loop?

Thanks for your help.

Welcome to Android Central! Was this an official Lollipop update over-the-air, or did you manually install it from somewhere else? If the latter, are you absolutely sure you picked the correct firmware for your model? The wrong firmware can cause a bootloop to occur.
