the s5 is read only file system. did you make a new july rom with 4.9.0 in it?
i know NH has one but its the 4/15 firmware not the 7/15
No, I would not know how to do that.
I do not want to use the NH fork, I like it straight from the source. I don't mind having to install it after reboots, I won't be rebooting it very often.
