Upgrade : A new version of the popular AOSP 9.0 GSI ROM is available as a software version 107 And unsurprisingly, there are plenty of bug fixes and performance improvements, but that’s not all. The update brings the latest Android security patch for November 2018, adds stereo to the Galaxy S9 and Note 9, fixes S-Pen issues on the latter, and improves the performance of recent Pie apps in the duo along with the Huawei P20 Lite.
The same update also fixes boot issues on some Android 8.0 devices, passphrase in the hotspot, and fingerprint issues on certain Xiaomi and Huawei devices. To get this new update, you can check out this link, which also has the full changelog.
Here’s some good news for everyone who wants to install the Android 9 Pie update on their device, as long as it supports Project Treble. A project ROM based on AOSP Android 9 is now available for download.
This means that if your device supports Project Treble, you can update your device to Android Pie immediately.
Yes that’s how it is. This is an amazing development, as many Android devices support triple projects, and this ROM gives them a direct – unofficial, by the way – upgrade to Android 9, and you can do all of this yourself at home.

Should I install Android 9 GSI
Well, if you desperately want the Android 9 Pie update, why not? But you must be willing to take the time to understand all of this (it’s not that difficult, by the way) and you agree to waive the warranty on your device. We are always willing to do this kind of thing, but we would understand if you are new and upset with what is at stake.
For the moment, As the August 29th, the third version of Treble ROM has been released as v103, and it improves things a bit for sure. The developer has noted that it is looking to take more bug reports from various devices.
If you want to use a stable ROM, then right now is not the best time to do it. Wait until the end of September 2018, we assume until a stable ROM is available.

How to find the correct ROM?
You may be wondering how can I tell if my device has an A or A / B only system partition, and what is the architecture type (ARM / ARM64) of my device?
Well, you can find those details about your device on this page.So, make sure to download the correct ROM depending on the A / B partition and the type of architecture (as we saw with the Pie Gapps as well) of your device.
If it is an A-only partition, then download the A-only system image from above, according to the Architecture of your device (ARM, ARM64, etc.).
How to install Android Pie GSI ROM
Unless you are an experienced ROM flasher, we recommend that you DO NOT try! This is simply too much for anyone installing a custom ROM for the first time.
- Make the backup appropriate from your device as it will need a factory reset, which would wipe everything on the device.
- Make sure you have unlocked the bootloader of your device and that you have the latest TWRP recovery installed. Find TWRP recovery here.
- Download Latest Android 9 Project Treble ROM from above based on architecture type and system partition type on your device, as explained above.
- Extract the downloaded file to get a system image file in .IMG format.
- Connect the device and transfer the IMG system image file (ROM) extracted to the device. Keep the device connected.
- Make sure you have the option enabled USB debugging on your device. You may have to do it again after unlocking the bootloader.
- Now open a command window inside the folder where you have the TWRP file from above. To do this, go to that folder, type cmd in the address bar of that folder’s window, and then press the Enter key. A command window will open, and its location will be that folder.
- Boot your device into recovery mode. To do this, run this command: adb reboot recovery
└ If you get permission dialog on your device for “Allow USB debugging”, press okay .
- Caution!]Tap on Erase and then perform the swipe action at the bottom to perform a factory reset on the device. This will delete everything except the contents of the internal storage and the SD card. Make sure you have a backup of your contacts, app data, etc. (You can now disconnect the device from the PC.)

Treble Android 9 Pie update issues
As mentioned above, the Triple Android 9 ROM is in the earliest phase of its development. So much so that the developer has clearly mentioned that he is inviting users to try this trial version and report any bugs they find – because they will – so that the ROM can be fixed for all known issues.
The ROM is said to be working with the Oreo vendor image at the moment, but work with the Android 9 vendor continues.
With that said, there is a list of questions available, as outlined below.
Issues as of August 29, 2018 (v103):
- Front camera on the Razer phone
- Stock AOSP camera app on some devices. Use the OpenCamera application
- Android 9.0 Vendor
- Many graphical glitches on the Moto E5
Also, Gapps is not available at the moment, so you may not want to go for this ROM right now (Aug 21).
That is all. Please let us know if the Treble ROM is working on your device or not.
