Yeah, I'm guessing that the version of Linux in the kernel has been changed and it that the mempodroid exploit hole has been closed for 4.0.4? Did you see the new output from the scripts where it tries to list whether the root files are now present (for rooting) or not present (for unrooting)? The mempodroid exploit binary doesn't report success or failure, so its hard to tell that it works--that's why I added some new lines of code in the script. Here's the root example output: View attachment windows-root-example.txt Here's the unroot example output: View attachment windows-unroot-example.txt Can you point me to the 4.0.4 OTA you used? If I have time tonight, I'll try installing that myself and see if our suspicions are true. Thanks!
