I have a rooted droid Razr running Gingerbread 6.12.181.XT912. Version 2.3.6. I have another rooted Razr running ICS. I want to upgrade the Gingerbread phone to ICS without losing all my apps and data (which is quite extensive). The OTA does not work. So, I need to do it the manual method. Could someone please point me to a link on this site or youtube with directions on how to do it? I have searched but there are so many versions of instructions out there I don't want to do the wrong one. I need to get to the latest version of ICS and maintain root, apps, and data. Thank you!
