By flashing this you should understand that I am not responsible for bricked devices. In order to flash this file, you would have already rooted your device, voiding the warranty. YOU are choosing to make these modifications, and I take no blame or responsibility if you brick your device and/or your device catches fire.
I would like to start off saying that I used the eMMC dual boot option referenced here [eMMC]Updated Dual Boot Guide[CM 7.1+][Phiremod 7+][Stock 1.3] and ran into the problem where the main partition (CM7 in my case) was booting normally, however, the alternate partition (Stock 1.3 rooted) would continually boot loop. After research, I found out that it was boot looping due to the incorrect versions of Adobe Flash and Air being installed. They were also installed to /system instead of /data.
I found two excellent guides located here and here that helped diagnose the problem. Unfortunately, these only helped with the primary partition.
In order to fix the boot looping of the alternate partition, I modified the updater-script provided by jaromnelson to reflect the alternate partition.
What this file does is removes the incorrect Adobe Air and Adobe Flash from /system folder on the alternate partition and installs the correct Adobe Air and Adobe Flash to /data folder. DO NOT INSTALL THIS FILE IF YOU ARE NOT RUNNING eMMC DUAL BOOT by Taosaur. If you continue to boot loop after you install, you are not boot looping because of Adobe Air and/or Flash.
Download the file located here
Put the file onto your SD Card
Boot into CWM recovery
To be on the safe side, Wipe Cache and Dalvik (not sure if this helps but I do it anyway).
CWM > Wipe Cache Partition CWM > Advanced > Wipe Dalvik Cache
Reboot into your alternate partition and enjoy.
I am by no means a developer, just a guy that does a lot of research.
