Hi,

Hmm, that is strange.
Looks like your battery may have drained out.

If something is wrong , the phone will get stuck in a bootloop - you will see the MMX Icon forever.

Please charge your battery and remove and put your battery again and give it a shot.

It can also be a prob with your hardware too - maybe the power on button isn't working.

Do the above or go to a cell phone repair shop.

Hope this helps
