Generic System Images (GSIs)

There are a couple of GSIs that you can flash over stock Android 14 by just flashing the system.img:

The one provided by Google: https://developer.android.com/topic/generic-system-image/releases#14-stable

• Tested version: aosp_arm64-exp-UQ1A.231205.015-11084887-e291b838.zip
• Everything works except:
  • no sound in calls
  • no VoLTE

This one built based on Lineage 21 (xda, github, download)

• Tested version: lineage-21.0-20241017-UNOFFICIAL-gsi_arm64_vN.img
• Everything seems to work except:
  • VoLTE requires a Settings app checkbox to force it, and correct APN settings
  • While voice LTE works, SMS sending/receiving is not stable (in my case SMS receiving)
• This build is useful because it gives adb root access and you more easily inspect the rest of the stock firmware.
• If this build doesn't work (didn't work when testing once on 1IV), try "TD" version. One that booted and seemed to work during light testing was lineage-21.0-20241018-UNOFFICIAL-arm64_bvS.img

Note that stock ROM boot images have to be used here. We cannot mix AOSP and stock kernels, at least the tests so far failed.
