Bricked OP2 ...

Hi all

I bought the oneplus 2 4 days ago.
I rooted it, installed twrp and flashed nethunter2.0 CM12 then wiped cache , well the flash didn't go very successfully as the os still oxygen but i had all applications from nethunter installed and fully functional.
I decided to use the nethunter installer provided by the official site but not including the onplus2 version, i included the custom rom in replacement of the choosed one
.. but accidentally in the process of this tool it flashed stok for nexus which completely bricked the phone... nothing works, not boot no charge no sound...

I plugged again the phone and pressed for 20 seconds the power + volume up button and i got the bulk usb driver as it was a oneplus one .. i changed the driver settings to accept the unsigned drivers and updated the unkown device to the qualcomm 9008 ( as it was like a oneplus one ) .
The issue is that oneplus two has a Qualcomm MSM8994 Snapdragon 810 and the version i found for ColorOS is only for MSM8794 .. so i couldn't do anything

please can anyone help me?
any hint please?

Thank you in advance
