Losing the “unlocked bootloader” warning screen on Moto X Pure 2015 Edition

After unlocking your bootloader, explained here, Motorola replaces your nice custom greeting with an obnoxious boot splash warning screen.

Very annoying and obviously written by lawyers. I’m surprised that they didn’t mention ebola. I lost my custom greeting, probably forever, which I did not expect.

On the good side, Hashbang173 provides an easy solution. You can read his post for the details, but the bottom line is to simply download the fixed logo.bin file from Hashbang173’s post and flash it to your phone. To flash the file, open a terminal under Linux or a command prompt under windows. Then:

  1. Ensure that your phone has USB debugging enabled in Developer options (see here)
  2. Turn off your phone
  3. Enter fastboot mode by holding down the power and volume down buttons simultaneously.
  4. Connect the phone to your PC with a USB data cable
  5. Make sure that you have a connection by typing “sudo fastboot devices” on your PC and look for a response like this:
    • $ sudo fastboot devices
      $ [sudo] password for bob:
      $ 1234567890    fastboot
  6. Change to the directory into which you downloaded logo.bin
  7. Flash the logo.bin file by typing “sudo flash logo logo.bin”
  8. You should get a fastboot response indicating the flash was successful (sorry, didn’t save that output)
  9. Use the volume buttons to scroll to Start and press the power button to reboot the phone
  10. Enjoy seeing the standard Moto boot flash, sans obnoxious warning screen

Many thanks to Hashbang173 at xda-developers for his work.

For the braver souls, makers_mark wrote a Windows program to modify logo.bin with custom boot splash images. I may try it eventually, but I’m not that good with graphics.
