Trying to go back to earlier posts to figure out what happened. I am guessing the error 7 is due to trying to install 215...possibly on a rooted phone.
Whatever the original problem was, macpro's suggestion is going to be the best solution. To go back to bone stock, then install 215, follow these steps:
Going back to stock .211:
*On your pc, download and install Matt's Razr Utility 1.8 or 1.81 or 1.82. You can find 1.82 here:
Droid Razr Utility 1.82 [Windows] For Verizon Droid Razr And Droid Razr Maxx Only - DroidRzr.com
*Extract that utility to its own folder on your computer...you must extract the file on your pc. It will not work from your phone.
*After the utility is extracted, go to the Motorola drivers folder in the utility and make sure you have the latest Motorola drivers installed on your pc.
*make sure your phone is set to usb debugging mode (menu>system setting>developer options).
*Power your phone off. Then power your phone on while holding down your power, the volume up and volume down buttons simultaneously.
*Connect your phone to your computer with the factory supplied usb cable.
*On your phone select AP Fastboot, then in the utility select option 1..."restore phone to stock .211. Do not unplug the usb cable until the utility finishes.
*When completed your phone should reboot to stock .211.
*After running option 1, restart phone to make sure all is fine.
Install the .215 leak:
*check to make sure usb debugging mode is checked (menu-> system setting-> developer options).
*Then in settings, go to “Security" and check “Unknown sources."
*install the .215 leak following instructions here:
