Lenovo A3500-HV Bricked while flashing ROM ( Cable disconnected )

OS : Windows 8.1 (With drivers successfully installed ) X64
Also tried on Windows 7 (With drivers successfully installed ) X86
Using SP flash tool
The device had this ROM : A3500HV_A442_01_37_140920_ROW
and it is the same I was trying to flash

Hi all , My lenovo A3500-HV went crazy and I had to re-install the rom ..
but while flashing using SP ( all drivers are OK ) the goddamn cable disconnected at about 15% - 20% from total progress :(
CURRENT STATE :
DEAD :'(
can't power up , nothing happens after pressing power button
can't go into recovery mode or download mode ( nothing happens when pressing VOL UP & Power , VOL UP & DOWN & Power or any other sequence )
it is not charging when I put it on the charger or the USB
is not being recognized when I plug it in ( see attachments please ) !!
device manager screen shot attached please have a look
-----
any hope it can revive ?? , how ?? :(
or just go to the warranty ( really few days left ) .. note that it was rooted device .. ( ( will they ever detect the root if the device is dead ? ) )
