[HELP] touch stopped work [xt910] - Motorola Droid RAZR

Hello.
I have a big problem, an average day the battery of my device was discharged, and then put my phone on the charger, after charging the battery, the touch stopped working for no reason.
as shown in the video:
So I researched some things on the internet and tried to hard reset by following these steps:
----------------------------------------------------------------------------------------------------------------------------------------------------------------------
1.Power up the phone by pressing the VOL UP + VOL DOWN KEY together + PWR KEY .
2.The device will enumerate with different BOOT OPTIONS
3.Use the VOL DOWN Key to SCROLL and VOL UP Key to SELECT
4.Select Recovery
5.The device will start up with Motorola logo and power up to a little Android man logo with Exclamation mark
6.Press the VOL UP and VOL DOWN Key together at this screen
7.The device will display BLUE Text on a Black background .
8.Use the VOL DOWN Key to scroll DOWN and the PWR Key to SELECT the option desired .
9.In this case , press the VOL DOWN key till the Wipe data / factory reset is selected and press the PWR key to confirm the selection .
10.Use the VOL DOWN key again to select YES - delete all user data and press the PWR key to CONFIRM .
11.The device will then start performing the Factory Data Reset
12.Once the Formatting is complete , press the PWR key to confirm a REBOOT
13.The message rebooting is displayed on the phone.
14.The device will reboot and start the normal power up sequence
-----------------------------------------------------------------------------------------------------------------------------------------------------------------------
And ok, hard reset successfully performed, but the touch is still not working.
Now I'm stuck in the initial boot screen of system and if I touch one of the four functions below the phone vibrates, however the system does not recognize touches on the display

Never

The phone's warranty already ended.
The unit has also been dismounted.
The Motorola in Brazil no longer accept the device.

Hi,
It sounds like hardware failure to me. But for other opinions, I will have your thread moved to your device section.
Good luck!
