I used to have a milestone in which I updated it to 2.3 ginger bread, to do so some files needs to be copied on the sd card as you all know. Now I have a new atrix and I inserted the milestone sd card into the atrix then I've updated the atrix through OTA after download is completed I've pressed install then the atrix entered the menu that has some options like root, boot, wipe data, update from sd card.... I pressed boot. Then I did factory reset then it entered this menu again. Did I did something that void warranty. One more thing I have a message that is invalid battery type before I do the update, but not sure if it was before or after entering the sd card!! Could the old files caused this problem though all I did is inserted the sd card and powered my mobile.
