[Pero44]

Hello, I have been using sony xperia L (C2104) for the past three months. 3weeks ago I juat observed that the phone couldnt complete the booting process when I switched it on. I boot started booting, showed the sony xperia logo, when ahead to show the waving rainbow of colours and it got stucked there It doesnt go pass the waves of the sony colours . It only goes off if I remove the battery. Please what do I do?

Hi and welcome to the community! Since you're new please be sure that you have checked out our Discussion guidelines.

I suggest that you try to start the phone without SIM/SD-card. But if you experience the same behaviour, I suggest that you perofrm a software repair via PC Companion:
http://www.sonymobile.com/global-en/tools/pc-companion/

In PC Companion you press start on Support Zone > Start on Update the phone/tablet software > Repair phone/tablet (the blue clickable link in the message) > Follow these steps without having your device connected to the PC.

Follow the instruction that appears in the program and do not connect your device until this guide tells you how to connect it.
