Xperia L C2104 wont finish turning on

[Nymphadora1]

Today I downloaded `Fanfiction.net`app and my phone just restarted its self but doesn`t go beyond the screen with the color "flames"  

I Tried extracting the battery and turning it on whit the connection on th PC  but still there's no answer

Is there something to do about it?

If it won't start then I'm afraid to say your only option is to perform a system repair

Performing a system repair using PC Companion will often fix issues - This will factory reset your phone and erase all data

Switch off your phone and unplug from Pc (Hold volume up and power for around 10 seconds)
Start PC Companion and select Support zone then Update my phone/tablet then in Blue Repair my phone/tablet and follow the on screen instructions - When prompted connect your phone still switched off holding volume down or back button - This should start the repair or reformat process

If you are using Windows 8/8.1 or a 64bit operating system then adjust the settings for PC Companion and run in compatibility mode and chose Windows 7 or XP

Hi Nymphadora,

Welcome to the community,

You could also try booting in to Safemode and see if you are able to get in to the device, you may be able to remove the application from the settings.

Safemode instructions

In reality, if this does not work the information supplied above would definitely help resolve this issue.

Thank you both but either method can´t be used b`cause the phone can`t be turned on.
