I want to unroot my moto g. I can follow guides but on links where you have to choose, im lost. I am also having trouble downloading the correct program from the android website, its always a exe not a zip. I have a XT1063 specs . Any help on what i should download or links to good guides would be greatly appreciated. baseband msm8626bp Kernal 3.4.42-g668a77b system 21.11.23 titan build kxb21.85-23
