Im newly rooted, running EE 3.0 , and I would like to change my lock screen..... how would I go about doing so, with these instructions?? Im a noob....obviously Instructions: 1. Do a NAND backup first!!! I am not responsible for you bricking your phone. 2. Download this script --> Vanilla_Lockscreen_Wallpaper_Windows.zip (there is also a Linux one) 3. Download Lockscreen_With_Background.zip down below instead (Had to modify the original script; lots of bad stuff happened ) 4. Extract the files to a folder 5. Add your 320x480 wallpaper (.JPG or .PNG) to the Wallpaper folder 6. Plug in your phone to your computer 7. Execute the START-SCRIPT batch file 8. The phone will reboot when it is finished AND...how do I perform a NAND backup??
