Hello, I'm in great need of Appollo (zte imperial) I9101 boot image. I was working with the build.prop file through adb, and did the chmod 644 to system instead of the build.prop file. Now I don't know how to get permission of 755 to system, as I can't get booted, or adb shell. adb devices work on ftm screen, as well as fastboot and sideload, but no permissions other than that. Any help in that area?
