QHSUSB_DLOAD problem

pchetan2 said:

My xperia SP doesn't start but problem came when it vibrated suddenly 2-3 times and went off Unfortunately it never came back on ,doesn't charge ,doesn't get recognized by PC ,PC,and us or even flashtool
I also tried shutting it down by pressing yellow button on the back ,it did not work
I have left it to wall charger whole night and removed it now ,same problem but when connected to PC it is giving some sound and when removed it gives different sound (like the sound that comes when drivers are being installed)

i have kept my device connected to wall charger for about 5-6 hrs and now removed it ,kept it for the whole night ,still nothing

(unlocked bootloader, leaked 4.3 rom,battery while it shut down- around 20% )
any help please!!!!!!!!!
