[Question] Iphone 6 MKT6572 not out of the problem boot screen with "build.prop"

[Alexandre Ribeiro]

Friends, very cool forum, I see you know a lot about android, I have a problem on a Smartphone Hipone 6 clone, it is MTK6572, Iphoene 6s 819 model.
 
It turns out that he has no physical back button, so I "root" it and installed the "root browser" and put the line soft menu in the file "build.prop" I made a backup of that file, such as not like the soft menu, deleted "build.prop" and renamed the "build.bak" to "build .prop". did burrada to leave a "space" between the file name and extension.

Now the smart of the boot and the bootanimation this upside down.

Due to file "build.prop" being with the wrong name I think the "USB debugging" have been disabled and can not have have privileges "su".

I managed to copy the "build.prop" to the computer, but I can not rename it nor replace it.

I tried to "root" again but had no effect.

Would have any idea to solve this problem?

I thank your attention
