Forgive my lack of motorola experience, I am much more familiar with Samsung devices, but I am trying to upgrade my wife's Razr Maxx to JB. The device is stock rooted system version 6.16.211.XT912 Verizon.en.US I believe that means i am on version 211 as specified in the first post. I followed the directions but when I try to apply update from ext-SD I end up with E:Error in /tmp/sideload/package.zip (Status 7). Searching the thread turned up a couple of similar issues, but they were on versions other than 211. I did an MD5 sum check before moving the ZIP to the SD and it matched so I am at a loss. I have tried three times with the same results (most recently I did a temp unroot to see if that was the issue but no lock). I am able to boot up normally afterwards, but no update. Any suggestions? Thanks very much.
