Hello sburrell. By reset to default, do you mean reinstall the Operating System and completely start over? If so, just contact Motorola/Symbol or the vendor you purchased the unit from and get the exact Operating System type and version for your MC9090. Then you can download the correct OS installer from Motorola/Symbol. The packages come with a "readme.txt" that will instruct you on how to install the OS. I hope this helps. Good luck!

You may need to reflash the OS. you can normally download it from symbol webpage. you will need a cradle and an SD card.

The 9090 will continuously reboot when someone has cold booted it and has held the trigger down too long after the cold boot. What it's doing is looking for OS update files in the proper directory to do a system update. When it doesn't find them it just reboots again continuously.

To get out of this, cold boot it again but release the trigger right after you push in the battery.

Actually if it is continuously rebooting, it is usually because someone was holding down the trigger through a cold boot process. That's what puts it into this continuous reboot loop. To get out of it do a cold boot again (pop the battery part of the way out, hold down the power button and trigger simultaneously, and then push the battery back in while the power button and trigger are still down). But as soon as you push in the battery to the point where you hear it click, release the trigger. If you hold it in too long, the unit will start continuously rebooting.

Thanks,
