I do software development for a living, and I still couldn't breathe until the iRex finished rebooting... even though I'd seen it work in the emulator multiple times.

For the DR1000 an iRex developer told the following on this forum, I guess it will also hold for the DR800:

A software component (sysd) on the DR1000 checks for firmware updates when an SD card is mounted. If it finds one, it will ask you to install it and - when confirmed - hard reset the device. Pressing the reset switch does exactly the same (though without the recommended proper shutdown). The hard reset causes the system to boot into a special 'upgrade' mode - independent of the normal kernel - where it overwrites the root file system, kernel and other system parts when necessary. After the installation it reboots for a normal 'soft' boot.

So there is always a way back to the original firmware.
