Summary of what works and doesn't.
- Fastboot installation is tested and works.
Enable USB debugging. Reboot your device into Fastbootd if your recovery supports it:
$ adb reboot bootloader
$ fastboot reboot fastboot
or:
$ adb reboot fastboot
Now flash the GSI image you downloaded:
$ fastboot flash system /path/to/file.img
If you're on Linux or macOS, use sudo fastboot.
If you're on Android 11, download TWRP using this link. If you're on Android 12, use the TWRP provided by this Telegram group. You will need to flash a nulled vbmeta before flashing the Android 12 TWRP!
- Enter TWRP recovery.
- Do a clean flash if you're not upgrading a GSI version. To do that:
Wipe > Dalvik/ART Cache, Data, Cache. If you have already installed a GSI, you don't need to wipe Data (unless it's an Android update). - Start installing:
Install > Install Image > nameofthegsi.img > System Image > Swipe to confirm Flash. - Enjoy!
| Component | Comment |
|---|---|
| Camera | Working (No Pixel Binning) |
| Speaker / Mic | Working |
| Bluetooth | Working |
| WiFi | Working, 5 & 2.4 GHz |
| SIM / Mobile Data / Voice | Working |
| VoLTE | Not Working (a common issue among Samsung devices) |
| Fingerprint | Working |
| NFC | Working |
| USB headset | Not Working (from my experience) |
If your headset isn't recognized or not working, change these settings from PHH settings:
- Misc features > Force-disable A2DP hardware offload: On
- Misc features > Use alternate way to detect headsets: On If your system crashes when using Bluetooth, please turn off media recommendations.
Note: The camera quality and access to sensors depend on what camera app you're using and whether you enabled Camera2 HAL3 API.
