Sounds like you need to restore the stock ROM, just download it and flash using flash tool and your device will work again.
It appears the PureX audio may have corrupted the ROM and has prevent it from loading
Hope I could help

THANKYOU..!!

No problem, glad you got your phone working

I'd like to share my experience about, I had the same problem, what i do is to press power button and connect the phone to the computer (befere I tried to flash it with flashtools and I couldn't get the phone to enter to flashmode) a icon of the battery will appear, now start flashtool software (you should have the firmware downloaded previously) and follow all steps for reinstall android, this time flashtools recognize your phone.
I hope have helped, and sorry for my english I'm not english speaker.

try it

I think your phone just died. Stock flashtools are dangerous because these apps re-flash boot, partitions, system, and (sometimes) even a bootloader. If I remember well there was another user with the same problem. And no one was able to help him.

find somebody who knows how to use jtag.. by jtag u can fix d motherboard wic fill fix d brick

Hello, I understand your phone is still possible to connect in fastboot mode, then the solution is to flash a custom kernel in this way, make a full wipe, and install a custom rom. But he said this is only possible if you have unlocked bootloader, otherwise you'll have a hardbrick
Click thanks if help you

[Q] Xperia l stuck at sony logo even after flashing ftf

plz help me......my xperia l stuck at sony logo after soft reboot is done on cm12 thunderzap 4.13 and i already tried flashing a stock ftf but again it stuck at logo if i tried to install a kernel it stuck at kernel logo.......plz help!!!!

Do you had any recovery installed? Any recovery backup? Then u can use fastboot mode in flash tool. Any Problems faced during flashing?

No problems during the flashing its completed successfully.......and whenever i tried to install a recovery using fastboot mode its successfully flashed and again stuck at recovery logo......
is this a hard brick or what...?

hard brick means that you can't turn on the phone. Since you're able to see the logo, there's some hope.
Try flashing some other JB Kernel and then the stock ftf.
Hope it works

Download the Sony's flash tool then
Try going to fastboot then flash a recovery (try both flash tool and command prompt).
If it works format the system partition using the recovery and reinstall the new ROM
If it didn't work go to flash mode then flash the stock ROM using flash tool (you need to download the rom file your self) after flashing you will boot into stock ROM
If you already know what I mean good luck if don't try googling or reply:angel:
