I want to install ClockworkMod recovery on my Motorola Defy+ in order to install Android 4.0.3 (ICS). Where can I get CMW to install? Are there any problems with ICS on the Defy Plus?
Luckily rooting the Motorola Defy is pretty simple and doesn't require any extraneous measures. Please see this link for a tutorial on how to root and install a custom recovery (ie. clockworkmod) on your Motorola Defy.
As far as installing an ICS ROM, after doing some research it appears there is not a fully functional ROM available yet. However, if you are willing to give up a feature or two, you may be able to get a stable release running on your phone. Please refer to the xda wiki page specifically for the ICS development status on the Motorola Defy for more information about the project.
