How to get the first Android 11 custom ROM: Back in May, Google’s annual developer conference Google I/O got canceled due to the coronavirus pandemic, and hence the Android fans were left with no hopes to see Android 11 anytime soon. Google released the first developer preview built of Android 11 back February 2020, exclusive to Pixel devices only. Recently, Google pushed the stable Android 11 update to its Pixel phones and uploaded the source code for the release to AOSP. Whenever a new Android build gets released, it takes around 2-3 months to develop a custom ROM based on that version but this time with Android 11 it’s a little different.
About the new Android 11 Custom ROM
An XDA member has successfully built a pure Android 11-based AOSP ROM. That’s quite a thing cause it’s only been a few days since Google pushed the stable Android 11 update to its Pixel phones and uploaded the source code. Xiaomi devices have always been very popular in custom ROM development, developers just prefer to make custom ROMs for Xiaomi devices and they have proved this yet again.
This First Android 11-based AOSP ROM is available for Redmi K20 Pro/Mi 9T Pro. The ROM is completely functional with all basic features like Wi-Fi, Bluetooth, camera (photo and video), audio, sensors, LED, GNSS, and most importantly, RIL (for Calls, SMS, Data and VoLTE) are working. The only known issue as of right now is is that SELinux is set to permissive, which has serious security implications. This build is not recommended for daily use as it is not so stable plus there is a constant security threat.
Some more facts about the first android 11 custom ROM
But you still can enjoy the first Android 11-based AOSP ROM on your Redmi K20 Pro/Mi 9T Pro but flash this ROM at your own risk as this ROM is still in the beta phase and there are a few security issues with the build right now. The ROM is just like stock Android 11 with no fancy customization options. AOSP ROM is Nexus devices stock ROM without GApps. So you gotta flash GApps separately with this ROM.
Back then with Android 8.0 (Oreo), Google announced it’s Project Treble and that has helped to make Android more and more modularized and this has allowed developers out there to make custom ROMs closer and closer to Generic System Images, or GSIs. A big credit goes to Project Treble that has allowed the developer to make a fully functional build based on the latest Android release, Android 11 within days of its launch. A developer has also made a statement that Google’s Android 11-based GSI can boot on most Qualcomm Snapdragon devices that launched with Android 9 Pie or Android 10, the condition applies that a few changes are made for vendor compatibility.
Now, all we have to do is wait for the manufacturers to release Android 11 on their devices and also wait for developers to develop more Android 11 based stable custom ROMs for different devices, this can take a while and all we can do is sit back and wait.
