Thanks for hard work, I'll try when I get new type b cable :O
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
Hi !

Finally the camera works perfectly on Android 13 ( LineageOS 20 ) ... it was a issue in the kernel, for which I had to perform a small hack to fix it ... only yesterday I realized that the camera issues are kernel related, and today I managed to solve this issue.

Unfortunately the sound part is much more complicated ( because it's not like there's an error in the kernel or in my source - but the problem appeared with Android 12, when Google dropped audio support for devices older than Android Oreo) ... and the only solution is to go back to Android 11 (LOS 18.1)
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] l1ll3l:
I have zero knowledge only love and curiosity. Read about the issue and the upgrade about the audio hal in android 12 which was upgraded to version 7 or so. Tried to come up with solutions like somehow pointing the earpiece location of the mate 8 drivers to our bottom speaker than by editing the mixer files activating stereo. But it seems the drivers are not open source. The mate8 has only 1 speaker if I'm not mistaken. According to my limited knowledge to solve the issue would be very difficult. to be able to activate one speaker is already a blessing. But the functionality of this ROM is way better than before and smoother I'm really grateful for your effort and achievements on this device.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
you are not very far, this is the way I fixed the stereo sound in the wired headphones (before the sound was heard both in the wired headphones and on the device at the same time) ... so I changed a mixer with one from Mate 8 ( EMUI 8 ) and the sound in the wired headphones was fixed ... unfortunately I can't find something similar for stereo speakers
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
Please, this thread will be suspended for a while ( meaning no development support for LOS 21 ) - will be activated later when I'll restart working on LOS 21 !

LOS 20 will recive soon a new update, I already have attached a preview of the upcoming update, so please move the discussions to the LOS 20 ( Android 13 ) thread for a while, thanks !
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] Brain789:
Since I read the two last bits of the discussion I wonder if it would be possible to add the lower speaker as output device for the same audio signal (mono) that is played by the upper speaker.

To be honest, I don't think that stereo matters very much when the speakers are so close together. Mono on both speakers would definitely give more room filling volume in my opinion..

Edit:

Same comment/question applies to LOS 20, for sure. ;)
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
I've also heard something like this in the past as if it could be implemented, honestly I don't have the slightest information about how we could implement this proposed by you
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] Brain789:
Thanks for your prompt reply!

It's not that bad as it is now since usually I don't even need sound. And if I do I normally use my earphones. Was just an idea for a shortcut from someone who doesn't know about the sorcery you do.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] ziwoyidai11:
你好:)作者我是华人，我非常喜欢这款系统，丝滑流畅，但同时也有些许小bug.在这之前看了所有以下回复并没有人提及，所以我想说下问题，中国的酷安软件点击图文链接跳转浏览器黑屏重启不知道是不是软件问题，至少在LOS系统之前版本没发现，还有扩展SD卡无法作为内部存储，存储安装软件。我打开了开发者选项强制安装软件到外部存储权限打开后也没有得到解决问题！还有就是扬声器问题了，同事感谢作者还能让M3体验到高版本系统的体验！仿若新生！
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] chaos03x:
i will try to translat it:

Hi:)developer I am chinese.I live this ROM very much,It`s incredibly smooth and responsive.But it also has some bugs.

I’ve read through all the previous replays, but no one has mentioned these issues. So i want to report these issues：

When I click on the image-text links in the Chinese app Coolapk, the browser goes to a black screen. I’m not sure if it’s an issue with the app itself, as I didn’t encounter this problem on systems prior to LOS21.

Also, my external SD card cannot be used for installing APP. I’ve already enabled the option in the developer settings to force software installation to external storage, but it hasn’t resolved the issue

The last issue is the Audio.Finally, thank your for allowing us to experience the higher system versions on the Huawei MediaPad M3! It has rejuvenated my tablet as if it were brand new!”
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] chaos03x:
我觉得为一个软件单独做适配不太现实，然后扬声器的问题作者应该在上面回复过了，SD卡不能安装软件我倒是没试过，因为我不用SD卡:ROFLMAO:
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] chaos03x:
你可以试试抓取logcat反馈给作者
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] ziwoyidai11:
试过容卡，试过命令重写强行把软件安装Sd卡上然后报错格式化，然后就是移植了！我再学习移植，一个类原生真得就是再求本溯源的系统，小白玩了伤不起，深入玩了又上瘾，打散驱动包然后做比对，查代码做比对，修改后适配，太难了！全是网上资源，有点鸡肋
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] chaos03x:
没试过融卡，不能不融卡直接把软件装在外置SD卡吗？
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] ziwoyidai11:
不可以的，要不软件用不了，要不格式化SD报错，这个作者的产品我都试过，经过两个月刷机各种研究LOS现有的版本，发现一个问题，每个版本都有缺陷，每个版本都不同，从修复过，比如上一个版本双声道，下一个就是单声道，下一个双声道，相机又不好使了，下一个版本相机好使了，存储又是好使的，在国内好多东西都存在吊鱼现像，找刷机教程不缺，ROM工具得花钱，想修复得花个100RMB，设备都不值那个钱了！我会在各大平台发出这个第三方类原生系统的尽告！浪费时间多些时间挣钱换个好设备，不要在系统上浪费时间！！
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
can you translate that posts that are not in English are ignored? thank you
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] chaos03x:
Sure, I can briefly summarize what we have discussed.

He tried to turn a portable SD card to internal storage via ADB commands but encountered many issues, such as errors during formatting SD card or software not functioning correctly.

He's also frustrated by not being able to find a perfect ROM, as every LOS versions has some unresolved flaws. He's even considering learning ROM development himself, But the development tools he found cost 100 CNY(13.84USD), which is half the value of the tablet.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] Robocop3422:
Hello,

give it any news about the following bugs for the Model BTV-W09 (without LTE):

- Only one Speaker works

- No Camera works

- Hardware-Button makes only FPS, no striped

- The Case will not detected

- refresh rate in videos are a little bit lagy

- And separate Build for this Model without Telefon-App, Contact-App,....

Big thanks for the Developer(s)!
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
Camera fully working on LOS 20, the rest are known bugs

Edit : Lineage OS 20 has also separate build for Wi-fi (BTV-W09)
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] Sarn.m:
Previously I used Huawei mediapad M3 DL09 EMUI 5.0 Android 7. Later I installed Lineage OS 17.1, 19, 20 and 21 using each version. I like and am impressed with version 21. Very fast and smooth. Thank you very much to the creators and developers. But I found something that Some app installations also include a notification requesting android. Version 8.1. Go up
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] puma2k17:
HI @surdu_petru

thanks for your amazing work over so many years!

I am using a BAH-W09, curently on lineage OS 17.1

If I understand it correctly, the newer version are not available for the Mediapad M3 Lite 10 such as BAH-W09, correct?

Latest for me is still 17.1 ?

Thanks!
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
yes it's LOS 17.1 ( Android10 ) , ... but you posted in a wrong section, here it's development for Beethoven devices ( BTV ) not Bach devices ( BAH ) .
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] harrisc:
Hi

Would you be able to provide any indication when this might be released for SHT-W09 8.0.0200 (C567)?

Thanks

Chris
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
Yes, I'm still working on LOS 20 for Schubert, there's some issues with the kernel for Wi-fi devices, and I guess that you can help me testing my kernel on your device because my device it's LTE ( SHT-AL09) - and here all are working well
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] harrisc:
I am happy to try different installations but I will need some close directions
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
first we will test the kernel on EMUI9.1 (I hope you have this version on your tablet) - as soon as I have something concrete I will send you a private message (PM), maybe in two weeks or sooner, thanks !
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] harrisc:
Unfortunately I have SHT-W09 8.0.0200 (C567) as mentioned above.

I never could get the upgrade
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
I will send you a link where you can update your tablet to EMUI9.1 - LOS 20/21 will be based on EMUI9.1
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] harrisc:
I am willing to do the update
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] jeanfrancois78:
Hi everyone,

I'm a complete noob trying to install LineageOS on my old Mediapad M3.

I have already unlocked the device and installed TWRP 3.7.1.

But now the instructions on the first post are a bit unclear to me

Could you explain a bit ?

Perform a clean wipe for the first install ( wipe cache as well ).

What do you mean here ? Data, Cache and Dalvik ?

Flash the latest build available

I guess I should put lineage-21.0-20240210-RELEASE-beethoven.zip onto the SDCard and go to Install menu

But what about boot_w09.img ??? How do I install that ?

optional flash ( always the last available packages ) GApps

Same question, how to I install this one ?

Thank you very much for your help,

Jean-François
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
Please, go to Lineage OS 20, everything is more advanced there, so you don't need to install boot.img afterwards
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] jeanfrancois78:
Salut Surdu,

I actually found how to install OS 21. I haven't played a lot with it yet but at least, applications that were not working anymore on the stock OS (Lichess, AthleTV for instance) now work fine 👍

Thank you very much for putting together this release. It's awesome work!

Jean-François
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
Thanks, btw here will be no update anytime soon, that's why I told you to go to LOS 20 which it's working even better than LOS 21, camera it's fully working there and also the LOS 20 will be updated monthly with new Google security patch
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] jeanfrancois78:
Okay understood. Then I guess I'll switch to LOS20. Any advice on how to do that?
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
In the same way like you did it for LOS 21 , also you have all info in the OP ( LOS 20 thread )
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] seraphmon:
Hello! I got this set up on my BTV-DL09 and I have read that the audio is partially working, but are there workarounds or some sort of fix to this? I'm willing to flash a different ver of LOS and my device is also running the lastest version of Magisk. TYIA
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
Yes, check LineageOS 20, camera are fully working there and the both speakers working as well
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] seraphmon:
How ever I recall that the wifi and bluetooth on LOS 20 are only partially working, has that been fixed?
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] dima-82:
Newest Android version is not always the best option.

@optimumpro's Jaguar ROM for OnePlus devices proves this.

The ROM is up-2-date regarding security patch level and kernel version but still based on Android 11 (!!!).

But most people do not understand this and claim that they need Android 14, 15 etc.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
maybe Android 14/15 is also good, but not on a device that no longer supports these new versions - on a device from 2024 it is normal to install Android 14 instead of Android 11 😂

EDIT:

after the summer vacation, starting from September-October I'll continue working on this version of LOS, at the moment I'm satisfied that LOS 21 (with the latest QPR3 update) can still be installed and run successfully on my BTV-DL09 tablet - the part remains to be fixed of sound, bluetooth and SIM
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] dima-82:
I run my OnePlus 9 Pro (from 2023) with Android 11 :p

On every release for the M3 you publish, you have the latest security patch level as well.

I think it is not just merging Google commits into you ROM, I assume it is a lot of manual work (y)
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
Only vendor security patch it's update by me ... the whole system security patch of LOS 20 it's merged by LOS Team from Google, so it's not my work there.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] radiklz:
Hi Surdu, all,

First and foremost huge thanks for you enormous effort and kindness of sharing this work with the community. As much as you might enjoy doing it, you wouldn't have to share it anyways, and this shows a lot for someone.

Now with the question, I installed the ROM yesterday and I'm surprised on how fast and stable it is, i don't miss anything important.

Nevertherless, I am curios as to know if it is possible to enable fingerprint navigation ? (BTV-DL09)

I have looked around , also in this post I am surprised to see no one mentions it, or at least I didn't find it.

Thanks a lot for you time ans support.

Regards,
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
thanks, it is activated on LOS 20 but only partially... also there the camera works 100%, it is more stable and newer including the latest security patch... here (on LOS 21) the activity is currently suspended and will not be soon a new update, it would be best to install LOS 20
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] Robocop3422:
ok.

Do you know with which update you fix the issues? Or with which release and when you release this?

Thank you for an answer.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
Yes, check the LOS 20 Thread, the issues was fixed long time ago !

EDIT:

Of course that you should install the latest update, as usual the latest update has all the improvements made to this ROM since the first release of the LOS 20 ROM on this tablet until the release day
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] Robocop3422:
I know. But my Questions are related to LOS 21.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
Sorry, no further development here .
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] Robocop3422:
Is it safe that LOS21 is no longer developed for device BTV-W09?

If so, how can you get down from LOS21 to LOS20?

For LOS20 all this bugs works?

- Only one Speaker works

- No Camera works

- Hardware-Button makes only FPS, no striped

- The Case will not detected

- refresh rate in videos are a little bit lagy

- And separate Build for this Model without Telefon-App, Contact-App,....
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
Yes, check LOS 20 thread and you'll find out.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] Vio EG:
Thank you
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
Settings -> Security & privacy -> Device unlock -> Screen lock -> here you can choose what you want !
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
Hi ! I have prepared some improvements performance and Ui for the new update !

I don't think you will exceed more than 1350 ( 3D Mark - Sling Shot ) if you try to do a test on your device ... here it's my new score after performance improved ! ( ... not to mention that stock Android N will not exceed 1100 )
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] Brain789:
That really sounds promising! Looking forward to testing the update.

Up to now, I have to say that I'm impressed by the stability and usability of the initial release already.

So, I guess that this is a version that will soon be the best I've had for my device ... seven versions later than the abandoned EMUI nougat... !

Cheers!
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
Hi !

There is a new update in the OP for LOS 21

Changelog:

new security patch: February5, 2024

HWUI & performance improved

EDIT:

Lineage Recovery 21 was released in the second post !
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] Brain789:
The new update just booted up successfully on my BTV-W09. Many thanks @surdu_petru !!

It's running well and a little bit smoother than before. :)

Out of curiosity, I ran a benchmark before and after updating.

Geekbench CPU scores:

Pre update:

- Single Core: 375

- Multi Core: 1233

Post update:

- Single Core: 377

- Multi Core: 1251

I also wanted to run the GPU benchmark but it crashed few seconds after its start. Could this be a hint why the particular game we discussed is not running @surdu_petru ?

Edit:

Scrolling big web pages is now much smoother than before.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
I noticed that the GPU does not run on Geekbench, I think this is also the reason why certain games do not work, at the moment I have no idea what it could be wrong
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] Brain789:
Could it be related to the hwcomposer restrictions that you once mentioned?
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
Yes, definitely, especially since many games need Vulkan support, which unfortunately is not present on our tablet
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] Brain789:
There we probably have it... Geekbench only offers Vulcan as GPU API, no OpenCL present (which I have on my Smartphone).
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
Yes, I guess that we have only 1.0 ( we can check into vendor/etc/permissions/android.hardware.vulkan.level.xml )
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] Brain789:
Yes, it's 1.0x. Please find an overview screenshot below.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] Brain789:
Is it possible to update or install Vulcan or other 3d graphics APIs on our device or do we need to stick to a blob from Huawei?
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
yes, we need to keep Huawei blobs ... but graphics mali ( libGLES_mali.so ) blobs and vulkan (which in our case it's just a symlink of libGLES_mali) was updated from stock Huawei Android Oreo ( even if there is no EMUI8 for our device - I picked them along with the right kernel drivers from Huawei Mate 8 which have a chinese version of EMUI8 )

EDIT:

I picked from Mate 8 because we share the same soc hi3650 ... and without those update from Mate 8, development on this device would have stopped at Android Oreo/Pie!
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] Bocchi_Renewed:
booting fine & camera worked on d-01j.

audio is only missing maybe?
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] PiKa5623:
Thank you very much for adapting the version of Android 14.Why does this version still only have sound on one speaker.I'm here to give you a suggestion next time do not put on mega network disk, I prefer you can put on Google network disk
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] Brain789:
Sounds like a sophisticated jigsaw puzzle you put together for the community!

Thanks again for the explanation and the additional background information.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] friedsonjm:
Up and running!
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
I can make sound working 100%, but in this case bluetooth, sound recorder & video recorder will stop working ! Let me know if you want to test a version of LOS 21 in this way, thanks !
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] Brain789:
If you could keep Bluetooth functionality and provide Video & Sound for streaming in video calls only, then this would work for me. ;)

But I guess it's all interconnected.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] Brain789:
By the way, regarding Camera, I found that QR code reader (QR scanner PFA, from F-Droid) works in horizontal and vertical mode.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] Bocchi_Renewed:
i don't care abt those functions、can you send me that version?
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] Brain789:
I would be interested in the test version as well.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] friedsonjm:
I would appreciate it if anyone else might see if the syncthing app works on this ROM on their tablets. For some reason, even after giving permissions, it can't write the configuration file needed to work on mine.. FYI syncthing is a multi-platform Windows/Linux/Android/Mac file synchronization program... good stuff.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
Maybe BT can be fixed.... but at the moment I have not been able to do this

Yes, the new camera application in the last LOS 21 update, perform a bit better ( if you have 2 camera icon - you need to perform a clean install of the last LOS 21 update)

Yes, I can provide this build in a few days as required some extra work

Ok, the build will be working on all Beethoven devices ...but introduces the new issues previously mentioned.

in fact, certain audio functions from the LOS source code must be rewritten to return compatible with LOS 18.1 (this is because in LOS 18.1 the sound works perfectly on our tablet) - there are things that are usually not done (and I am referring here to the modification of the LOS source code )
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] Brain789:
Thank you, @surdu_petru !

For the now and near future I will stay with the system's stream you've already provided. No need to setup something special for me.

If you plan to issue a version with sound and Bluetooth fully working while (partly?) disabling camera, I will be interested since I don't really use the camera. It's more an aspect of feature completion for me. Also on the stock system I only started it to test it and then forgot about it.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
Yes, camera will still working but without video recording.

Edit: I'll provide a new build with sound working mor for Japanese devices, as they don't have sound at all with the current build of LOS 21
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] Brain789:
So, then I am looking forward to this!

Video recording is not necessary for me. One use case for the camera could really be video calls over MS Teams or Google Meet, the other use case would be QR code reading for WiFi access e.g. in hotels (I know this is one for the lazy guys).

For taking photos, I will use my smartphone or my digital camera - they are both much more handy than a tablet for this purpose plus the picture quality is higher.

Out of curiosity: Is my understanding correct that storing of the video is the main issue, so the bottleneck is video compression and then writing to storage?
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
no, camera video recorder can't start because audio issue ( also I don't understand why, as sound it's working properly... but may be because reverting some audio source code into LOS21 as I explained before )
