This tutorial will broadly walk you through how to flash such a ROM. Since Treble is so new to users and the process to flash them is a little different compared to the usual custom ROMs, there’s been a lot of confusion about how to flash a GSI onto a Treble-compatible device. But as we’ve seen with the in the case of each of these devices, the ROMs that are available thanks to Treble support are mostly functional (there are some differences in terms of what works and what doesn’t, and the community has put together a wiki page you should check out to find that information). Without Project Treble, developers have to employ a lot of tricks and hacks to get their custom ROMs working, and while Treble support doesn’t solve everything, it certainly helps kickstart the process.ĭevices like the Huawei Mate 9, Honor View 10, Huawei Mate 10 Pro, Honor 7X, Exynos Samsung Galaxy S9, or Allview V3 Viper would have had either no AOSP-based custom ROMs available due to lack of developer interest or ROMs lacking some basic hardware functionality. This means that devices that were once running heavily customized Android versions like Samsung Experience on the Samsung Galaxy S9 or EMUI 8 on the Huawei Mate 10 Pro can alternatively run software closer to that of the Google Pixel 2.Īfter-market custom ROMs (customized versions of Android software that are made by independent developers usually not affiliated with a company) are a big draw to the XDA forums, and thanks to the changes in Android that Project Treble require, Treble-supported devices will have an easier time flashing custom ROMs based on the Android Open Source Project (AOSP).

At XDA, there’s another benefit that we’ve spoken about at length: the ability to boot an AOSP Generic System Image (GSI) on any supported device. If you’ve only heard of Project Treble in passing but haven’t looked into it all that much, then you may have heard that it’s supposed to help major Android updates roll out more quickly.
