Default [Q] Can I backup 3G communication driver from an Android Phone?

Hello
Is it possible to back 3G communication drivers from an Android phone(Moto Razr V MT887)

Background: It is a China specified 3G(TD-SCDMA), the Android system is not very good.
I want to flash an international ROM, but not able to find any with TD-SCDMA communication driver.

My idea is:
1. Backup TD-SCDMA communication driver from present China specific Andriod first.
2. Flash an international ROM of MT885(WCDMA), I think it is easy to find.
3. Install my backup TD-SCDMA driver maually.

So the first thing I need to do is to backup the TD driver.

Is it possible?
