I flashed the logo on my moto g5s and now the bootloader wont show properly and the phone wont start anymore (only shows N/A at the start and wont go further)

Edit: The Phone starts now, but the bootloader is still broken after flashing the logo

Many Thanks

Hello,

After the unlock of the bootloader via Motorola Website, you have probably noticed the M logo has been replaced by a Warning message...

Here is the solution to restore M logo :

Bye

Thanks for the file and work to change the annoyance. This worked perfect on the Moto G with Android version 5.1

Did someone try this on a Moto G8 Plus ? It doesn't work.
The new logo appears but then I get another warning screen (not the same one before flashing logo.bin) and then the logo reappears.

Unfortunately, this did not work for me on my Moto G 5G. The picture shows up but then it goes to the unlocked bootloader warning and continues to boot as usual. :(

    Hello,

    After the unlock of the bootloader via Motorola Website, you have probably noticed the M logo has been replaced by a Warning message...

    Here is the solution to restore M logo :

    Extract the file in attachement in the same folder as fastboot, you will find "logo.bin" file.

    Enter in Fastboot mode :
    - Shutdown your phone
    - Push and maintain VOL DOWN and press POWER to boot your phone (A black screen with white lines should appear)
    - Plug USB Cable

    Flash the M Logo with fastboot :
    - fastboot flash logo logo.bin (success message should appears in the DOS windows)
    - Unplug USB cable
    - Press POWER and the phone will shutdown
    - Start your phone with long press on POWER and check your M Logo.

    Bye

    Thanks for this. Works like a charm.

    One Question: Any chance to get the 'Motorola Dual Core Technology' boot logo?

    Thanks in advance!

    Give me the picture your want 540x540 px and it should be possible.

    Edit : you can try the one in attachement :

    fastboot flash logo dual_core.bin

    I prefer this one (in attachement)

    Well the boot image is the kernel and all the other fun goodies that the device needs, so yeah, what you're asking for has nothing to do with the boot.img

    What you're asking for help on is the logo.bin file

    palmbeach, I think you misunderstood what I mean by "boot image". I know the difference between a ROM (what you are taking about) and the logo file (I've been rooting/ROMing since the Moto Droid - was a BB convert, and was ROMing there too). Here when I use "image" I use the actual definition of "picture" or in this case "logo". I'm sorry I wasn't more clear in my post.

    I am trying to create the boot image picutre using the above PNG image. Just looking for the method for converting PNG (or other image types, I have the pic in other formats as well) to a fastboot safe flashable image to replace the annoying Motorola "Warning" boot image. No one (unless I missed it) seems to be willing to give up the method to create custom "boot images(or pictures)".


    anyway, I did find the missing step in creating these files buy putting my device at risk, and fiddling with the image files, lucky for me I got it the first try:

    1. Create image In RAW format and 540x540 in size using your editor of choice (GIMP FTW).
    2. (the missing step) rename your "image.raw" file to logo.bin
    Code:
    mv image.raw logo.bin
    3. plug in phone, run command:
    Code:
    adb reboot bootloader
    4. Once in fastboot run commad:
    Code:
    fastboot flash logo logo.bin
    5. If successful run:
    Code:
    fastboot continue
    - Enjoy your awesome new boot image (picture)

    Thank you
