Step-4: Most ROMs don’t come with Google’s copyrighted apps like Gmail, Android Market and others. Download the Google Apps zip file for the Rom that you have installed and navigate back to BootManager. Tap on “Install ROM” and select Google App’s zip file. Save it in the same slot used in step 1. Do not check the three “wipe” boxes this time just leave them as they are. You can now get to the original ROM with the Google apps installed by booting into that slot.

Users who know that their ROM come with the Google Apps installed can skip this step and move on. Just remember that while flashing a new ROM, check all three “wipe” boxes but while installing an add-on to a ROM don’t check any of them.

Step-5: Move to BootManager and select “Boot Installed ROM” . It now displays a list of the ROMs that you have installed in your device from which you have to choose one that it will reboot into ROM. BootManager can be installed on each of your other ROMs also. You can also boot into and switch back to your main ROM as long as you are signed into Android Market on that ROM.
