Recently there has been some awesome development on the Droid RAZR thanks to developers like Dhacker and Hashcode who have brought Roms like CM9, CM10, and AOKP to this device! Hashcode has developed a really safe way to run all of these Roms via his Safestrap Recovery! Developer "Raziel23x" has added to the fun with a Patch that will bring BootMenu to any of these Roms. BootMenu allows you to run a second system using the SDcard and SDcard ext. This patch will work on both GSM and CDMA versions of the phone. To install this you will just Flash your main Rom, then the patch, then the GAPPS. You will need to be sure to run Rom Converter with the option in BootMenu.
