After downgrading your device, you can tweak it even further and make it even faster (Updated december 2022).

This manual is written for use with a Windows 10 x64 PC but you can use ADB on other devices.

NO USB CROSS CABLE IS NEEDED, we can do all of this over LAN/Wifi.

Notes

App = Application = Package = Program

Launcher = Homescreen = Desktop = Home

Network debugging ADB

ADB or ‘Network debugging’ is used over LAN/WiFi/WAN (manual here) or connect via USB (cross).

Other launcher

TechDoctorUK has pointed me in the right direction to customize your homescreen
to your very needs, clean, smooth and no f*cking ads, ever! Yay.

Use “Downloader” (PlayStore)

To install third party apps, we need to install an app that can install .apk files:

1. On Shield: Search and install “Downloader” from the appstore
   
2. On Shield: Open “Downloader” and grant file permission

3. On Shield: Go to: Settings -> Device -> Storage ->
   ENABLE: Transfer file over local network
   
   Take note of: username/password
   and: IP address
   
   
   
4. On Windows: Open file explorer and type // followed by the address of your shield, for example

\\192.168.2.200

5. Prompt will show: put in username/password
   
6. Navigate to \\[IP ADDRESS]\internal\Downloader
   if the folder doesn’t exist, repeat step 2

7. Download, extract and drag files to the folder

Alle video’s zijn in de maak

Download

~4MB

Now on the Shield device:

8. Open Downloader and navigate to Files
   You should see both files appear in Downloader-app
   
9. Select+OK+Install both files “TDUK_LauncherManager-ATV_1.0.3.apk” and “WolfLauncher_0.1.9-Wolf.apk”
   And delete them afterwards (hold OK button for context menu)
   
10. Open Launcher Manager
11. Grant access permission to Launcher Manager (Android will prompt you, if not go to USB debugging and revoke permissions and grant again when prompted, this will also disconnect ADB.exe)
    
12. Open Wolf Launcher and follow instructions here, topic starts @5m00s

Remove unwanted apps and services

Below is a list of ADB commands to uninstall a lot of apps and services, they will never (re) appear or update, EVER.

Remove all unwanted services and apps so your devices is without telemetry or spies from Nvidia or Google. Other services have been properly named so you can choose wich ones you want to uninstall.

re-installing any of the services is always possible!
