your firmware is in the list....so pull down official kitkat EMUI2.3_G750-T00_4.7.16.zip from huawei site, exctract the zip and copy the DLOAD folder on your sdcard.....then open the upgrade firmware apk and run local upgrade chosing that DLOAD folder you previously copied in the sdcard....

if your actual B137 firmware has not been modified deeply ( meaning uninstallation of required apks.... ) , if you remove root and have stock recovery installed....it should go through...

try....
