So you got the Edge S and want GApps? Basically you unlock your bootloader, root with Magisk, then install MagiskGApps.
DISCLAIMER: UNLOCKING YOUR BOOTLOADER MAY VOID YOUR WARRANTY, AND DOING ALL THESE THINGS IN THIS GUIDE MAY RESULT IN DAMAGE/BRICKING YOUR PHONE. I AM NOT RESPONSIBLE FOR ANYTHING YOU DO TO YOUR PHONE. PROCEED AT YOUR OWN RISK.
1. Unlock the bootloader: that should be doable with their global bootloader unlock website
here.
2. Download
Lenovo Motoroa Smart Assistant (Rescue and Smart Assistant), and follow its instructions to "rescue" your device. It will lead you to boot into bootloader mode and download the firmware. Find the firmware file via the LMSA's downloads (should have a "show folder" button). You'll need the boot.img file for Magisk.
3. Download
Magisk, then follow its instructions. You'll have to copy the boot.img to your device, then use Magisk to patch the boot file, then copy the modified one to your PC.
4. You'll need fastboot. If you don't have it already, you can download the Android SDK platform tools
here. Then go into the folder, Shift+Right Click the folder, then "Open Command Prompt" or "Open PowerShell," you should have something close to one of those two. Copy your Magisk modified .img file to that folder, then you'll want to input:
fastboot flash boot [modified .img file]
Once that completes, you should see in large text, "Start" on your phone next to the power button. Press the power button, and it should boot, and you should have root now.
5. Download
MagiskGApps to your phone, open Magisk on your phone, click the button that looks like a puzzle piece at the bottom of the screen, "Modules." Click "Install from storage," locate the MagiskGApps file, and install it. After that it will ask you to restart your phone, do that, then you'll just have to be patient as it takes time once its restarted to load everything. You also may need to update some or all of the apps, then you should be able to use the notification to finish setting up the phone with Google Setup.
Thanks to Motorola for making it easy to unlock their bootloaders
Thanks to the whole Magisk team for making an easy, awesome root (and more!)
Thanks to
