Now, what happens when you boot the device, you will get the so called "big scary warning", the device knows that you have used open mode rescue kernel, and each time you boot you will see the warning.

It is completely harmless, though, even as it says something about voiding your warranty.

What I suggest you would like to do, is the following; It is fairly easy to remove the warning forever, and also set your device to open mode for best performance and tweakability.

• 1.) First you need to flash the devide totally clean, using the rootfs+emmc flashing. Aftre this the device is in "totally clean state"
• 2.) then, you should disable the "big-scary-warning" forever. This must be done when device is clean as it cannot be done in open mode.
• 3.) After that, you should flash the open mode "aegis-neutering" kernel which gives you capability to run real root.
• 4.) Then, boot again the device with the rescue kernel and restore the backups from tarfiles. This way all your previous settings, files and applications are restored.
• 5.) Last thing to do, remove the few aegis files that store your saved passwords. You need to regenerate these with new open mode keys.
