Re: why Xperia U restart all the time

it is called a bootloop.
where you trying to flash it with a custom rom?

try to repair it using http://support.sonymobile.com/gb/tools/pc-companion/ (assuming you did not unlock bootloader)

If you tried it flashing with custom rom, try to do the process again,

Hi @arch9804,

You can try removing the battery in your Xperia U to stop this. However, if the same thing starts again when you put the battery back in and power on the phone you should try performing a software repair using PC Companion as nolramlb suggested.

Do you get as far as step 10 in the software repair guide (http://talk.sonymobile.com/t5/FAQ/How-to-perform-a-software-repair/m-p/1061294) before you are unable to proceed?

Do you experience the same without the SIM and SD cards?
