There are a few ways to remove Android OS from a phone. The first way is to use a recovery partition. This is a special partition that Android OS creates on your phone when it starts up. To remove Android OS from your phone, follow these steps:

  1. Boot your phone into Recovery Mode by pressing and holding the Volume Down and Power buttons at the same time until you see the Android OS logo.
  2. Once in Recovery Mode, select “Wipe Data/Factory Reset” from the menu that appears.
  3. When you’re done wiping data, select “Reboot” from the menu and press OK to confirm.
  4. Your phone will reboot and you’ll be back in normal mode. Now you can remove Android OS by following these steps:
  5. Open a command prompt or text editor and type “rm -rf /system/etc/android/com.android.” This will remove all of the files thatAndroid OS has created on your phone since it started up.
