I wrote an OTA Root Keeper script for Android 4.3+, probably some of you will find that useful:

+Pau Oliva Good catch on the append, I've changed it to replace instead of append inside SuperSU.

However, if grep doesn't exist, the return value is 127, and thus nothing happens.

Also note that grep is available by default in AOSP builds since 4.2 (and it certainly is available on my Nexus 7 both on 4.2 and 4.3), and as this script only matters on 4.3+ and nothing happens if grep is missing on 4.1 and older, the grep dependency should not be a problem (and checking for suid simply doesn't work right half the time as explained earlier)

Obfuscators:

I'm seeking Android app samples from the following obfuscators, latest versions preferred. I prefer a in production app from the Playstore, or a to spec built sample (not a sample from the company and not a sample built with a demo version).

DashO
Irdeto
Shield4J
Stringer
Zelix Klassmaster

Any help would be appreciated

If anyone is interested, I've published the first post of a series that will explain how to debug the Super Street Fighter II Turbo ROM in MAME. The first post explains how to create a "change difficulty" cheat.
