[Wear OS General] Lodovik:
Yesterday, I've successfully installed Facer and about 40 watch faces on my LG Urbane paired to an iPhone.

I've made a tutorial with detailed steps so others may try it and enjoy their Android watches. My knowledge of the Android system is limited so there may be some obvious shortcuts to my solution. Some steps are a little vague because finding details on Google about them is easy. This has been done an a Windows 10 x64 system and repeated successfully on another Windows 10 x64 system. Not tested on another version.

1 - Enable debugging on your Android Wear device

2 - Install 15 Seconds ADB Installer:

Note: you may have to disable your antivirus as this application may be tagged as a false positive

3 - Connect your device with a USB cable (either directly or with the charger) and wait for plug n play to detect it

4 - Open an admin command prompt window and type:

adb usb

You should see "Restarting in USB mode". If not wait a little and try again. If your device is still not detected, you may have to install more specific USB drivers.

5 - On your device, give the "always" authorisation for the connection

6 - Type:

adb devices

and you should see 1 device attached

7 - At the command prompt, type:

cd %userprofile%\Desktop

md facer

cd facer

8 - Now, you will need to put the latest Facer APK into the facer folder we've just created on the desktop. Note: Since I already had the paid version Facer on my Android device, I used a little Android app called "Apk Extractor" to regenerate the Apk file from the installed app. An older Facer version will work but some watch faces will have bugs (I tried first on the 1.6 version and it worked but some newer faces weren't perfect)

9 - Back to the command prompt to rename the Facer APK so it will be extractable:

ren *.apk facerapk.zip

10 - You should now have a facerapk.zip archive into the facer folder. Right-click on it and select "Extract all" to unpack the archive to a folder of the same name.

11 - Now, let's get the watch app to the current folder and rename it so it will be easier to work with it:

copy facerapk\res\raw\*.apk

ren *.apk facermicro.apk

12 - Facer can now be installed on the watch:

adb install facermicro.apk

13 - Make a folder for the additionnal faces:

md faces

14 - Go to FaceRepo and download your faces into the "faces" folder. They will have a .face extension

15 - We need to change the file extension to zip:

ren faces\*.face *.zip

16 - Now, right-click on each file and extract it to its default folder using the "Extract all" option. You can use WinRAR (if you have it installed) to select them all and extract them to separate folders. A free version of WinRAR can be easily installed from www.ninite.com.

17 - Back to the command-line to remove the zip files and transfer the faces to the watch. Type:

del faces\*.zip

adb push faces/. /sdcard/Facer

You're done! If everything is OK, you can select the Facer watch face and select your face by tapping on the gear icon of Facer on the watch.

If you ever need to remove Facer and start from scratch do this:

adb uninstall com.jeremysteckling.facerrel

adb shell rm -r /sdcard/Facer

The Facer folder on the watch must also be removed since uninstalling the app leaves it behind with the custom watchfaces.

If you want to reinstall Facer, restart from step 12 with a command prompt from within the Facer folder.

You can add more faces by repeating steps 14-17 with different faces files.
