Well,
first, your color and CID number you can see with many different programs, such as FAR, WOTAN client, XS++ and so on...
second, to your first question, debranding is done by flashing your phone with "General" or "Unbranded" firmware, wich you can do using on of the programs I claimed above.
How to use them you can easily find on the forum or even on Google...
If you don't find your way, let me know, I redirect you (I need to look for it too).
