No you can not relock the Bootloader, that will not work, so you need to have the Bootloader unlocked.
I think you will need to install Magisk, in order to hide apps, like Banking apps etc.

I guess if you just try to use Banking apps with unlocked Bootloader it will not work.

I am using Nova Launcher as launcher as there are a lot of things which can be customized.
I have never used OOS12 so I dont know how these rounded corners looks like.

Also, the dev of this ROM had just mentioned some days ago that he does not have time anymore to Maintain this AEX ROM, so I guess you should better try some of the other great custom ROMs.

I just switched yesterday from this ROM to Project Zephyrus ROM.
I'm looking for a ROM with no bugs finger print working and excellent battery backup.. especially idle drain.. can someone recommend one??

I faced a bug few days ago. My device was stuck on home screen and kept blinking. Couldn't change anything, or settings and was not taking any touch responses. I had to reset my phone to fix it. This happened 2-3 times and after 3 resets, it is working ok. I do not have screenshots or recordings but it usually showed system UI has stopped working. I am using a one plus 9r.

    * do some research if you have any concerns about features included in this ROM
    * before flashing it! YOU are choosing to make these modifications, and if
    * you point the finger at me for messing up your device, I will laugh at you.

    Read the whole OP! Be respectful to each other and don't ask for ETAs, it's considered as being rude!


    AOSP Extended is an AOSP based ROM which provides stock UI/UX experience with useful customizations. Being based on AOSP it provides a smooth experience. We have added useful customizations from various other open-source projects and have tried to keep our things simple. A ROM by a user, for a user. #BeExtended

    Download ROM for your device!

    Download OnePlus 8T /9R Build


    Want to try this awesomeness?
    Rich (BB code):
    -Make sure that you have backed up your data and are familiar with your device
    Also make sure that you have unlocked your bootloader
    Have a custom recovery installed on your device or use the AEX Recovery provided (Orange fox, TWRP or any other recovery like the PE recovery will work. Don't use LOS recovery)
    If you are using adb sideload, we recommend AEX recovery over TWRP, since TWRP doesn't work fully on A12 yet.
    Steps to follow for Twelve with GApps Build:
    1. fastboot flash recovery recovery.img ( only if coming from other ROM/ Stock OOS )
    2. Reboot to recovery
    3. Format data/factory reset
    4. adb sideload
    5. Reboot to system
    Steps to Follow for Twelve ( Vanilla Build ):
    1. fastboot flash recovery recovery.img ( only if coming from other ROM/ Stock OOS )
    2. Reboot to recovery
    3. Format data/factory reset 4. adb sideload 5. reboot back to Recovery ( and not in ROM ) 6. adb sideload the GApps package / Micro G package 7. reboot to system 8. it will throw error and ask for format ! Do the Format once! 9. reboot ! You can either sideload magisk zip or can patch boot img. Recommended to root only after the first boot. -Reboot your device

    First boot will take a few minutes! Have patience

    Clean Flash is always recommended!

    I guess there is nothing wrong in reading facts!

    -Why no "Incremental/Delta updates" Support?

    ->The updates we provide monthly are heavily changed and modified than the previous builds. New stuff is merged and added. So we don't provide incremental updates and recommend a clean flash.

    -How do I root this ROM?

    ->We recommend Magisk

    -Which Gapps are recommended?

    ->GApps Included

    -Will this ROM relock the bootloader?


    -When Will Be the Next Update?

    ->No ETAs, please. ROM Will be updated whenever the new build is ready by your maintainer. We generally provide monthly updates with the latest security patches and new features.

    -Adaway is not working :(

    ->Download it from here Adaway

    -SElinux Linux mode changer app is not working nor Busy Box installer app is working.

    ->Everything is good with the sources. You should try other things first and then contact your maintainer.
