drizzt112 0 Report post Posted March 14, 2016 I I have a Mygica ATV520E. under settings-> about device it says android version is 4.1.2 so i followed the instructions here viewtopic.php?f=18&t=1665 to upgrade to 4.2 However instead of booting from the SD card and loading version 4.2. it goes to the factory settings screen. Now in this screen there is an option to upgrade from img, but when i choose the SD drive it cant find it, even though i did copy the files there exactly as per the upgrade topic above Share this post Link to post Share on other sites
