Hey everyone, for some reason I don't always get a notification that someone has posted here. Not just this thread but most threads on XDA.

In any case I've still been working on this ROM, I have a new update for testing. It's been updated to use the new MIUI 14 vendor and I've removed a whole bunch of Xiaomi services that don't work under AOSP. MIUI 14 firmware is also included in the ROM.

Although flashing over an existing install is perfectly fine (tested by myself) I'm not going to push this build to the OTA system as it could be considered a "beta" build.


A few people have commented about bugs with the camera/media, I'm not able to reproduce anything on my end. If I can't reproduce it and nobody sends me a log then there is zero chance of it getting fixed.

Also the thing with the camera dot sometimes being on the wrong side, my java skills are terrible so if anyone wants to volunteer to fix it then go ahead :)

Imma test this right now.

Is Gapps included in this beta build? Which one should I use if it isn't? Thanks for the ROMs

Hi ! First of off, thanks for your work, about the bugs, how should go about making a log for you took at ? Thanks !

Also, another bug that I have not seen anyone mention, QR scanner doesn't work when trying to launch it from my web browser (Firefox), it just shows a black screen.

Hey there, I have just updated to los20 from los19 and it's actually eliminated some of the bugs i had encountered for a while now. I think a13 theming is lacking a little regarding accent colors. Does anyone know a way to set truly custom accent colors in the wallpaper & design settings? Pls don't recommend LWP+ i tried that and it's not really what i am looking for.

Thanks for you hard work Inkypen!

EDIT:
I found a way so this post is now kinda useless.
For anyone wondering how I got what I wanted - theres an app called Repainter with which one can customize all system colors and even make pure black background colors for oleds.

OK, so @Inkypen I have been daily driving the latest "beta" for 3 days now and:
  • battery drain is gone :)
  • media/camera handling errors still happen - though evidently less often - I am still trying to find a reproducable way to force the error and log it
  • everything other works - google pay, quick charge, wireless charging, google assistant, bluetoth, screencasting etc... everything is OK :)

Hey there I have an issue with safetynet not passing. The CTS profile check always fails, is there a way to fix this?

EDIT:
With Play Integrity checker I only get MEETS_BASIC_INTEGRITY.
MEETS_DEVICE_INTEGRITY fails.

Got another beta build for you to try with quite a few fixes/additions:

  • Safetynet issues are due to some changes Google did to their safetynet servers, this is now patched.
  • Fingerprint sensor not reacting unless you move your finger slightly is fixed
  • Lockscreen charging info added (was in last beta but I like the feature lol)
  • Github user KawaiiZapic was kind enough to have a look at the java code for the camera hole and has adjusted it so hopefully no more issues switching portrait/landscape modes
  • Updated Qualcomm SOC system blobs to newer versions (LA.QSSI.13.0.r1-09000-qssi.0)
  • Mark Akash ported Qualcomm's framework boost to AOSP, I've made the adjustments to enable this in Lineage (there is now a performance mode available in battery settings)
Also thanks to @Kingzak34 who managed to get me a log of the random media freezes, this is not an isolated problem and some devs I know have the same issue on their Xiaomi lahaina devices. Hopefully a fix can be found soon.

For some reason i still don't pass either play integrity nor safetynet tests. I have installed universal safetynet fix and shamiko in Magisk. Can this be solvedworks fine here with Magisk Delta and safetynet Fix Mod from HuskyDG. Maybe something wrong with your configuration.
Did u activate zygisk in magisk?

It works fine here with Magisk Delta and safetynet Fix Mod from HuskyDG

Magisk delta is unofficial fork of magisk with a few small differences. You can find it if you google. It's from HuskyDG.

Edit: i mainly use it because it supports some early mounting stuff which is beneficial for the Dolby modules i like to use.
Oh ok so I guess I don't need that I only use JDSP.
I flashed a modded safetynetfix i found on kdrag0ns issues page and now play integrity checks verify how they should.

Thx @Inkypen ... Testing it out. And it really seems great. Can i find a beta of this kind without build-in gapps? That would be great. Thx in advance.

I have a test version of the kernel which will hopefully solve the random freezes when using multimedia apps.
You need to reboot into bootloader mode to use this.

Use this command to temporarily run the kernel (will be lost on reboot)
fastboot boot boot.img
Use these commands to permanently install the kernel (Custom recovery and/or root will need to be reinstalled)
fastboot flash boot boot.img fastboot reboot

Download it here:

There also appears to be some issue with ANX crashing after taking a photo but other photo apps aren't affected. I'm investigating it at the moment, hopefully I figure it out quickly :)

    Got some good news, got ANX working back to the same level as before (mostly everything works except for slow mo/hdr video recording)

    Just waiting for March security patch to release :)
    3
    March update is out and pushed to OTA system. Google changed the camera API yet again for QPR2 but I worked around it and ANX is back. I also updated the firmware to MIUI 14.0.3.0

    Check the updater app in System settings to get the update or download from sourceforge

    I also updated TWRP and fixed fastbootd, so that is now working in case you have need of it.
    3
    I'm quite aware of all the issues with ANX. In the Pixel Experience thread I explained my reasoning for swapping out ANX with Google Camera in the latest PE build. It's becoming an uphill struggle to keep ANX functioning correctly, the current implementation is A13 source code hacked to be backwards compatible with the A12 camera libs and with each monthly security patch this approach is becoming more difficult due to changes to AOSP brought in by Google. I can't use the camera libs from MIUI 14 because they rely on certain symbols which don't exist in AOSP and no open source equivalent exists.

    I will try and get ANX working again but I can't promise anything. When Google finally decide to release the March security patch it's quite likely the next build will just have the Lineage Aperture camera app by default rather than ANX.

    Hi!

    Regarfing the ANX, is there any known workaround or alternative app that is able to use all 3 cameras?

    edit: some issues I've been experiencing since flashing this rom and even now after flashing this kernel, are ANX just frezzes when I select the .5x camera. And after taking a picture with the regular or tele lens, it closes, the picture is saved tough, but its annoying as hell.

    What can I do to help troubleshoot this issue? I'm just a power user though, not a programmer, I could provide logcat or something? Please let me know.

    Thanks!
    I've been using this GCam port https://www.celsoazevedo.com/files/android/google-camera/dev-bsg/f/dl129/ which works almost perfeclt - except the 0.5 lens does "squashed" photos - they look like they have been compressed horizontaly

    Can I try the kernel on Evo X ?
    It should work no problem, all the ROMs share the same kernel after all. If you're concerned that it might not work then use the first command which will just boot the kernel and won't permanently change anything on your device.

    LineageOS is a free, community built, aftermarket firmware distribution of Android 12 (S), which is designed to increase performance and reliability over stock Android for your device.

    Code:
    #include <std_disclaimer.h>
    
    /*
    * Your warranty is now void.
    *
    * We are not responsible for bricked devices, dead SD cards,
    * thermonuclear war, or you getting fired because the alarm app failed. Please
    * 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 us for messing up your device, we will laugh at you.
    *
    */

    LineageOS is based on the Android Open Source Project with extra contributions from many people within the Android community. It can be used without any need to have any Google application installed. You will need to provide your own Google Applications package (gapps). LineageOS does still include various hardware-specific code, which is also slowly being open-sourced anyway.

    Base source code is available in the LineageOS Github repo. And if you would like to contribute to the project, please visit our Gerrit Code Review.

    Working:
    Almost everything

    Broken:
    You tell me :)

    Downloads:

    https://sourceforge.net/projects/xiaomi-odin/files/12/LineageOS
    https://sourceforge.net/projects/xiaomi-odin/files/11/LineageOS

    Installation:
    Reboot to recovery
    Copy LineageOS zip to internal storage
    Install LineageOS zip package
    Install [optional] a Google Apps package of your choice
    Format data (wiping is not sufficient, formatting requires you to type "yes")
    Reboot

    Important notes:
    GApps can only be flashed on clean installs.
    Formatting data (all user data is wiped, including internal storage) is a must if MIUI was previously installed and device was encrypted.

    ROM Kernel: Linux 5.4
    Based On: AOSP

    New builds are up:
    • June security patch
    • Kernel upstreamed to 5.4.197 and latest lahaina CAF tag
    • LHDC Bluetooth codec added (untested as I don't have a BT device that supports this)
    • Some ANX tweaks (should start a little bit faster)
    Regarding the conversation about the visible camera hole at maximum brightness, that's a hardware limitation. You must have seen Xiaomi's promotional image of the pixel array above the front facing camera showing the smaller pixels allowing light to pass through to the image sensor. A smaller pixel will not be able to shine as brightly as a larger one hence the slightly darker view on max brightness. MIUI gets around this flaw by displaying a sun symbol over the camera hole at max brightness. On a couple of builds I tried limiting the max brightness by about 15% so this wasn't noticeable but I had a few people in sunny areas complain about the change, so I reverted back. If it bothers you just turn the brightness down a little bit.

    Are there any plans to fix the widevine level from l3 to l1? I know that the China/eu Rom habe l1,so it should not be impossible to fix
    I've had L1 support since before I even released any builds. Download any media codec info app from play store and check for yourself.

    New build is out, fixes seedvault among other things. Check changelog here: https://github.com/Inkypen79/OTA/commit/15f3c51b1ca99eaea2c026a47a6d0a02d3f5f583

    Turns out seedvault is a bug in Lineage, I used the main seedvault repo instead of the Lineage one and it's all working. This was fairly straight forward to fix but for future reference please, please, please provide build version and logs when giving a bug report.

    @subject4 Thanks for your suggestion. Nikgapps is actually what I would personally recommend if someone needed a gapps package, but unfortunately it can only be flashed on top of an installed ROM and is not suitable to integrate into a build from source.

    New test build is up. It has a new version of minimal gapps installed and it also passes safetynet from clean flash without the need of root or any additional patches or modules. OK Google detection is now working with the screen switched off. Biggest change is a much improved ANX camera experience. There are no more crashes when using certain camera modes, the only thing not working is slow motion. I'm considering making ANX the default camera for all future builds (gapps and non gapps) and I would appreciate any feedback about this change.

    Build is here: https://sourceforge.net/projects/xi...220426-UNOFFICIAL-gapps-anx-odin.zip/download
