URGENT Help Reqd. -- XSP Hangs at SONY Logo

Hi All,
I've accidentally wiped all User and System Data using CWM Recovery.
Now, Phone's neither boots up nor goes to FlashMode. It simply hangs at SONY Logo Screen.
I've tried switching off the mobile using OFF Button under the backover, but it reboots and comes and hangs at Sony logo screen.
Urgent help required, Please help.
Thanks,
Shankaran
Did you make a backup of your current Rom before wiping anything?
Sent from my C5303 using xda app-developers app
If u didnt make a backup of your ROM before, u will have to go SONY PC COMPANION and REPAIR YOUR PHONE. In this case, u will lose CWM and root. But nothing u can solve following this incredible forum. Im sorry
Solved

Thanks all.
The problem here was, I was neither able to Flashmode nor Recovery.
The trick to solve this
-- Open Back Panel of the Phone. Locate OFF on the back
-- Connect the Phone to PC, let it hang at SONY logo.
-- Start the Flashtool and Select the file to be flashed
-- Wait for Flashtool prompt to connect the phone in FlashMode
-- Now Press the OFF on the back with the Pen and Hold down the Volume down Button. You should be very quick in this.
-- It goes to FlashMode and Flash Tool starts flashing.

[Q] Xperia T bootloop

Hello,
I am having difficulties with my Xperia T (LT30i), first of all the boot button, hard or soft boot does not work. If I plug it into a charger it starts to boot but after the sony logo appears it will go black and then repeat the sony logo. It allows me to use the hard boot option, fastboot and flashboot when on charge but hard boot does not seem to have an affect.
Any help is greatly appreciated!
Thank you!:cyclops:

Bootloop AND not working Bootloader

Hi Guys,
I hope that anybody can help me to fix this problem.
My girlfriends phone doesn´t work at all since yesterday. Probably she installed a new update or anything else and now her htc one m7 is stuck in a bootloop. The problem: Everytime I open the bootloader via pressing on/off + vol. down the bootloop continues and I can´t select one of the options.
I think it is not possible to get the data from the phone, isn´t it?
But does anybody have an idea how to fix this bootloop problem?
vibration - black screen - htc logo - black screen ... and so on.
Also it is not possible to get access via computer because win doesn´t recognise the connection as long it is stuck in this loop.

If you can't get in the bootloader there is not much you can do...
Retreiving data from it will require the phone to be already bootloader unlocked, if its not already unlocked , unlocking it will wipe everything.
When you go to the black screen, just hit volume down. That's been getting me out of my boot loop into bootloader.
Or, power off completely (hold power down during your loop until it goes off), wait a bit, then try rebooting with volume down + power.

recovery mode

so I have seen some of the brick threads for this phone but i don't know exactly which one i should use. when i hold the power and volume down and let go when i see the sony logo it should boot into recovery mode but what it does is reboot and i see the sony logo again then boots into the phone. The phone works at least using it without cellular service because i haven't bought a sim for it yet. It won't boot into recovery and im hoping im able to save it. i did unlock the bootloader with the sony key that was given. so any help would be appreciated
thanks
