LG G pad II freezes at U+ LTE ME screen even during hard reset .p815

Hi

My LG G tab suddenly does not go beyond 2nd logo screen

I.e U+ LTE ME .

Automatically turns on after 5% charge and stops at the same logo screen.

so I tried to hard factory reset .

During factory reset it freezes in the same screen which is quite suspicious.

Mobile repair shop also tried to hard reset he also faced same problem.
