recover build.prop

I have edited my build.prop in my hyundai at7, i have backed up the original one but now i cannot restore it tru adb (because it's bootloop on logo and when i do adb shell it says that is closed althrou it's root)

I have try to root it again in adb but uncessecefull, i have try to push build.prop but it says closed, my only option it's to reinstall the rom.

Does anyone have a rom that suits this model?

Tks
