I would just download whatever ROM you are using, unzip it and pull out the unmodified /sys file. Then reboot via adb
and push that file to the correct path on your phone.
That way you don't have to edit anything yourself or delete important files. It's worth a try I guess.
Code:
adb reboot
Code:
abd push /path/to/file/on/computer /path/to/file/on/phone
