Not a comprehensive post, just a note to myself on what I need to do every time the device is updated and loses root + recovery (though the latter can be avoided by disabling the option to update recovery during system upgrades in Developer Options).
- Get the Bacon Root Toolkit (BRT), cousin of the wonderful Nexus Root Toolkit.
- Enable ADB on the device (it’s under Developer Options).
- Connect device, confirm BRT has detected it as an ADB device.
- This doesn’t always happen. In such cases (a) try a different port, (b) try a different cable, and (c) check that the ADB device appears in Device Manager. If it does not, reinstall the Google drivers using BRT.
- Flash Custom Recovery (my choice is TWRP) from BRT. This is needed to root the device. Default Cyanogen Recovery can’t do this. This requires a couple of reboots.
- Reboot into the Recovery and exit. I use TWRP, and when existing it checks whether the device is rooted and offers to root it. Go ahead and do that.
- SuperSU (and SuperSU Pro) are what one uses to manage root. (Apparently CM 12 allows one to do this using the in-built Privacy Guard but I couldn’t find any options for that. Another option is Superuser, but that doesn’t work on Android 5.0 yet I think).
- CM 12 also apparently has an option to enable/ disable root under Developer Options but I couldn’t find that on my device (before or after rooting).
That’s it! One of the reasons I went with OnePlus One and Cyanogen is the hope that the device will stay rooted after updates, but that isn’t the case. I guess this is so the OS and stay compliant with Google. So each time I do a major update I need to repeat these steps. This doesn’t happen often so by the time I get around to doing this I have usually forgotten what I did last time around. Hopefully I can come back and refer to this post the next time!
