mobile

Yesterday I picked up my phone in the morning to find that it would not turn on. I tried the usual power button + volume button combinations to get into recovery and download/flashmode but the boot loop seems impossible to break. I left the phone with the rubber band trick all night (around 14 hours) to pick it up this afternoon. No 3 buzzes from either rubber band trick, powerbutton + vol up or red reset/off button.
The only symptoms i have is:
When not connected to charger: screen off, led off, no buttons seems to work.
When connected to charger: Red led on, no buttons work.
When connected to PC: Red led on for about 8 seconds then off, repeat. No buttons seems to work.

The red led behaviour when connected to my PC seems to show that the phone is in some kind of boot loop. Flashtool log seems to back this up:

13/054/2015 15:54:43 - INFO - Device connected with USB debugging off
13/054/2015 15:54:43 - INFO - For 2011 devices line, be sure you are not in MTP mode
13/054/2015 15:54:58 - INFO - Device disconnected

This loops forever

Can anyone help me or do I need to get a new phone? The back of the phone have been smashed but I replaced it myself since im on a tight budget so my warranty is gone :/

Thanks in advance :fingers-crossed:
