Is not my work and I personally tested on my tablet Huawei S7 v104 from BestBuy.
The new boot.img is from Australian version(t-Telestra).
I have found this on a Belarusian forum.
For installation you need to have adb working(as superuser) and all the drivers installed. Put the tablet on the Fastboot mode and double click flash.bat
And use the rewords for the next development bounty of 2.2 or 2.3 or 3.
