Can’t unlock alcatel ot985

I’m unable to unlock alcatel ot985.I click on the direct unlock button and then connect the phone turned off(drivers previously installed) and when then gb key detects com port of the preloader and I see a message waiting for response from phone but meanwhile the phone starts up(!!),andoird logo shows on phone,the preloader disappears and obviously gb key gives a message that it was timed out.i have tried that numerous times to no avail.I tried alcatel otu toll and the phone doesn’t start up when I connect it to the pc because as soon as the alcatel otu detects the preloader it stops it from booting up as it should be.Same for SP flash tool.
I even tried to select ot918 model but that made no difference.
Can anyone please have a look at this and possibly try it out over teamviewer if needed?
