Hi, I've been trying to set this up on my Droid 4, but am having a problem that I've not seen anyone else mention... I'm obviously making a very fundamental mistake, but I just don't get the kexecboot menu appearing at all, and it just boots straight into Android. I've tried with both an update of Android and without, and all the fastboot commands come back with an OK, and Etcher seems happy with the flash. But on reboot, nothing different appears. I just get the red moto logo and then it goes into Android. Any suggestions / advice very much appreciated. Thanks
