  You’ll need an older Android firmware—likely Android 8 (Oreo) or earlier—before VT SWGP GR0, BZF1 support was introduced. Check XDA Developers or OEM archives for compatible firmware images.

  If you need to test your Android app on legacy firmware—specifically on builds where features like VT SWGP GR0 and BZF1 aren’t yet available—you have two main routes: use emulator/system-image snapshots for older Android releases, or grab factory/fallback images from device vendors.
  The simplest way to emulate an “old firmware Slice Master” environment is via the Android Emulator:
  1. Android Studio → AVD Manager
  2. Create Virtual Device → pick a hardware profile
  3. Select System Image → choose an API level that predates VT SWGP GR0 / BZF1 support
  If you don’t see the image you need, switch to the “x86 Images” or “Other Images” tabs.
  4. Download & Launch
  
  Because Google only adds new virtualization flags or kernel modules in specific API releases, running on, say, Android 9 (Pie) or below will guarantee neither VT SWGP GR0 nor BZF1 are present. This method is fast, free, and integrates directly into your dev workflow.

  I’m currently developing an app that needs to be tested on older Android firmware where VT SWGP GR0 and BZF1 are not yet supported. I've read through the previous messages—really helpful insights, thanks! stickman hook
  Just wondering: Has anyone pinpointed the last firmware version before these features were introduced?

  If you need older firmware versions for Android app development, especially ones that don’t support VT SWGP GR0 or BZF1, a good place to start is the official Android Open Source Project (AOSP) repository. They have archives of older releases that you can download and test with. Additionally, communities like XDA Developers often have users who share old firmware files or can point you in the right direction. Just make sure to check compatibility with your specific device.

  If you're looking for versions that don't support VT SWGP GR0 and BZF1, you might want to check out some of the earlier Android versions like KitKat (4.4) or Lollipop (5.0). These versions often have fewer features and compatibility issues, making them perfect for testing scenarios where you want to avoid certain functionalities.
  
  You can usually find these older firmware images on platforms like XDA Developers or GitHub, where many developers share legacy software. Just make sure to verify the source to avoid any security risks. If you’re working with specific devices, looking at the manufacturer's official website might also yield some older builds.Bathroom Renovations Parramatta
