Moto .ISO Mount Installer is a root application for most Motorola-made Android devices.
What does it do?
This is a manager & installer for loading ("flashing") an alternative .ISO file on a Motorola phone's 'CD-ROM' partition. With this app you can backup your existing 'CD-ROM' partition to your sdcard and flash a new one of your choice.
How can I tell it worked?
Each device type is unique, but if you disable USB Debugging and enable USB Mass Storage (if possible) you will normally see the .ISO mount onto your computer as a drive.
What devices will it work on?
Motorola RAZR, DROID RAZR, DROID BIONIC, DROID 4, Motorola RAZR HD, DROID RAZR HD, Motorola RAZR M, DROID RAZR M, Motorola RAZR i, and Motorola Photon Q 4G LTE.
Note that the DROID BIONIC has a much smaller 'CD-ROM' partition than the others, around 8MB.
This app is Open Source! You can compile it yourself from the github below.
You can compile it yourself from the source code, and if you really find yourself in need of an .APK version for free you can tweet me @mattlgroff and I'll send one your way.
