Marshmallow Update Procedure

When you have reviewed the features, issues, and made sure to disable Teleporter (Outlined Here) You can proceed to do the update using the following steps.

In All Apps, search for the System Update App, and run it.  



You'll see this:


Then click Check now. You should see this:


Click OK. Then you will see the following:


and then the download will complete...


and then prompt to run the Update:


Click Update Now.  The device will reboot, and you will see the little green Android man for a while, then the System Recovery/Update Kernel runs to apply the downloaded file as an OS update. The device will in most cases eventually reboot, and you will be notified that the update complete successfully. Be patient. This takes a while...


E:footer is wrong Note - you may encounter an issue here, and the device OS Update fails, leaving the following text messages on the R-7 display:


Android system recovery <3e>


Volume up/down to move highlight;

Enter Power button to select.


Reboot system now                                     (These are available commands )

Apply update from ADB

Wipe data/factory reset

Wipe cache partition

Apply update from downloads                    (until here )

Installation aborted.


If this occurs, it is because it is likely the userdata partition file system has orphaned Inodes, which get created under certain circumstances like a forced hard reboot, and OS crashes. These are not an issue under normal circumstances, but causes the System Recovery to not be able to reliably read the downloaded OS image data.

If your device does not have user data you want to preserve, then use the volume buttons to select the Wipe data/factory reset option and press the power button, and then rerun the above steps to run the Marshmallow Update Procedure System Update again, once the device has rebooted.

If your device has user data you want to backup, then use the volume buttons to select the Reboot system now option and press the power button, and then backup your user data once the device has rebooted. After that, run the factory reset procedure, and then rerun the above Marshmallow Update Procedure steps to run the System Update once again.  Sorry for the inconvenience!


The new build number of the Marshmallow ReticleOS in the System Settings should be:


The latest standard Apps are bundled/baked into the release download, so you should have all the Apps. Use AppCenter to check for any App updates after you update.



If you update, but then decide you want to go back to KitKat, we've provided a tool to use to do this, although it requires a Developer's Linux host you have sudo permission on. See this reference:
