[Q] Generic steps for un-rooting a custom ROM
Can someone shed some light onto what needs to be done to un-root a custom ROM? Basically I have a crappy old phone which I decided to repurpose for working with an MDM solution my company is using(Citrix Worx Home/Zenprise). I can't use the stock ROM because it's Gingerbread which is not supported by the Citrix app, so I had to flash CM9 on the phone.
The problem is that the app checks for root access. I tried using some tools like "Hide my Root" without success. Even if the SU app is removed, the root detection still triggers.
So I am looking for generic steps of what can be done to remove root access from a ROM which came rooted. Doing a search the only posts I find are more relevant to people who want to return to stock ROM and not unroot a custom ROM. Are there other things that need to be modified besides removing the SuperUser apk?
