how to unlock enable n7000 aws band samsung galaxy note 1 note I

Hello,

I searched but didnt find any solution for my n7000,

My n7000 is unlocked but it wont work with AWS tmobile and wind, I read that we have to flash modem or some file to OPEN ENABLE aws band on n7000,

Right now MY n7000 supports
GSM: 850, 900, 1800, 1900 MHz
UMTS: 850, 900, 1900, 2100 MHz

can you please tell me how to enable AWS band ?

I want to use t mobile/wind

Thank you for reading.
