I have had the same problem but i i used 4G and got it right. It is 70 MB in size, so it will not kill you data plan. But my 1020 did not like the update to .218 as it did noit unstall. The phone was getting to the spinning gears and then showing an unhappy emoticon on the screen and then rebooting and so on. Had to use recovery app with my pc to roll back b to 8.1
