[Moto G Themes and Apps] xpmule:
I downloaded it and it seems fine to me.

But are you flashing only the Logo.bin file via fastboot.exe / mfastboot.exe or is it inside a zip file ?

Just in case you or others did not know you can NOT flash them inside a zip file.

They have to have the raw file with .bin extension.

I would typically select the option "save as" in the Program then pick Logo.bin format (not *.zip)

Then i would copy that bin file into my Fastboot install folder.

Then i would run 2 Windows.bat files i made for Windows 7 x64 (or just run the command in them manually)

Here is what i run first after plugging in my phone.. CheckDevice.bat

@echo off
echo.
echo "Checking Phone Connection"
echo.
mfastboot devices
echo.
@pause

That tells me in the console if the phone is detected properly or not..

With a recent update to Marshmallow on my Moto-E 2015 i had to install "MTPEnabler" (found at XDA)

Because other wise my phone would default to connecting to the PC in Charging mode.

Which means i can't transfer files etc.. so that program auto connects in MTP mode for you.. GOOD PROGRAM !

Marshmallow is different now.. if you have it installed it now has a different connection behavior than Lollipop.

So be aware of that for one thing.

Anyway running that last .bat file should tell me i am good to go other wise trouble shoot your connection issue.

Then i would go ahead and try and flash it with Fastboot using another .bat file i made.. FlashLogo.bat

@echo off
echo ** Flashing Moto E 2015 **
echo.
mfastboot flash logo logo.bin
echo.
echo ** Flashing Complete **
@pause

And if you DO want to use a flashable zip format remember it can only be flashed from custom recovery like TWRP.

If you want to use the Flashable ZIp with your PC i believe you have to connect your phone in TWRP first

then put it into Sideload mode then fire up the side load commands etc

Which it may be easier to just copy it to the SD card etc and reboot into recovery to flash it.

AND and...

Since i had problems with the "saved" Flashable zip format the program here creates i had to make my own.

So save your Logo from the program as a Flashable zip file then extract it with something (i uses Winrar on Windows)

That should give you 1 folder with the *.bin file then inside a pile of folders

you will find 2 more files the updater-binary and the update-script..

So next i would copy inside and replace the script with the one i made i posted earlier.

(Although i am not sure if *ALL* phones use the same identical script or not)

BUT i did just NOW save both the Moto X Play Gen 3 version, and the Moto-E version Flashable zip formats

and they are indeed identical 100%

So my script "fix" should work for that phone to (and i am guessing most others)

Anyway so at that point you have the extracted flashable zip folder with the new fixed script put in there..

Now just pack it using Zip normal compression making sure you have the same directory structure as the original.

And that should do it.

It's easy to over look the simple stuff so i would double check your connected properly etc.

And trying to run the right thing the right way.. I did not see any problem jump out at me with your X Play Logo.
