As we featured close to a month ago, an XDA member came up with a SD card booting method for the Eris. Along the same lines as this, is this Linux based script developed by XDA Member unCoRrUpTeD. This is a very tricky setup and should only be tried if you’re comfortable doing these kinds of modifications.
If you’ve read past this then let me get into the details. This script allows you to dual boot 2 Roms on your Android Device. The script currently works on amonRA recovery with no support for Clockwork mod yet. There are a few steps you need to follow and it has directions for Linux and a VM running Linux based setup. It has detailed instructions on how to get setup, but you will need to follow closely as there are some pit falls.
To learn more about this, check out the discussion thread and give it a try.
