Tutorial [Q] Need help with qcn

Hi since this is technical, and Google has no answers for me at least I can't find any. I need urgent help on to repairing my imei on a qcn file, I can only use that since I will lose my AWS bands with Wind Mobile. I want to use the imei that is back of the battery and is same as my box that I have. I have 04 Imei right now. I don't know how to edit the qcn file with any hex editor, it's all bunch of algorithms of numbers and letters.
