@technonicx user thank you I installed twrp on the phone now i will install android 7.0 nougat

@technonicx user Nothing happens if you install TWRP while rooted.

@technonicx user If they are not rooted otherwise, they are uploading via TWRP. For example, I was doing so for GM 8 GO.

@technonicx user Nothing happens, you already need root to install TWRP Recovery from mobile, but if there is no root, it will be installed from the computer and then rooted.

@technonicx user Thanks for your help
