Hello @surdu_petru can you help me?

I tried to dirty flash the recent version of this ROM over the February version of my M3 10 as written in the post above. It bootlooped. I am rooted with Magisk 25 and TWRP. I was able to save it by dirty-flashing the February version again.

What is the process for a upgrade without losing data?
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
I always use dirty flash for update without any issues ! Of course I don't use Magisk !

Hi has anyone managed to get the auto trigger for Google assistant to work... Voice command 'hey google' or 'ok Google'? Sorry if this has been asked before but in the assistant settings the option for voice matching says unavailable on this device. I am using the m3 as an in car navigation and entertainment system so just want ok Google to listen and work when the screen is on (and actually is plugged in to power too).

I have installed on CPN-L09 but the camera doesn't work. Can it be solved?

Only video recording it's working as you can see on OP unders What's not working!

Hello.

Will you put in new versions with the latest security updates?

Hi, i updated my Huawei Mediapad M3 Lite to Lineage 17.1 (coming from 16.0) and I am noticing a really high battery consumption both in idle and in light tasks like web browsing. This did not happen in L16... I installed GApps (nano version), and have checked and activated all battery saving options, such as disabling location, background sync, but the issue persists. Can you please someone tell me if this something normal?

If it is, is there any safe method to return to Lineage 16? Thanks.

New Update LOS 17.1 !

Hi !

There is a new update of LOS 17.1 for our devices !

Changelog:

Best regards

Thanks for a new update
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] Thanh_Nguyen:
Thank you so much for your work. What a big difference updating from Stock to LineageOS 17.1. You revived my very slow old tablet.

It will be perfect if you are doing battery optimization for next version as it consuming 30% more than the original rom

And also, I am using BAH-L01 and it has fingerprint sensor. In previous stock rom, I could use it as Back button, for this LineageOS 17.1 where can I set the same?
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
Unfortunately the LOS 17.1 can't use fingerprint sensor gesture, I'm sorry for this inconvenience , so you can use the button only like unlock the device with the finger
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] Gelindo67:
Hi surdu_petru. thanks for your work on this version which is great. I would like to ask if this will be the latest version of lineage OS for this device or is it possible that there will be more in the future?
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] Grisu3000:
Hello, im new here and need help how i can install LOS 17.1 on my MediaPad BAH-W09,

i downloaded twrp and the firmware, but i don´t know what unlock bootloader means

i hope somebody can help me

thank you

[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
for the moment I haven't decided if I will switch to the next version of Android on this device, because it requires a lot of work and a lot of free time... which I don't really have at the moment
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
I'm sorry, but if you don't know what bootloader unlocking means, I advise you not to try to install a custom ROM on your tablet, or at least not now... until you familiarize yourself with the basic operations/terms

In my opinion, you will need at least one month to document yourself before actually installing a ROM or TWRP on your tablet, if you do not master the necessary notions and terms well, you risk that your tablet will become a brick, and the responsibility for this act is entirely on your shoulders ... the developer does not assume any kind of risk for the operations you do on your device ... I hope you understand well what risks you are subjecting yourself to, there were many cases in which users and they broke the devices only because they didn't follow (didn't understand) the steps to follow to install TWRP/LOS on this tablet! You can't say later, that you were not warned from the beginning!
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] csjjpm:
Hi Chris,

it is not simple but you will be able to do it. You need to read through a lot of threads to establish each step. It will result in your tablet being unusable but recoverable. You have to repeat steps or look for recovery steps.

Since we will have all done this a few years ago we probably cannot refer you to specific threads, you'll have to find them yourself.

Persevere you can do it and it is worth it.

Regards

[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] Grisu3000:
thank you, some years ago i did it with an chinese tablet and it worked,

the media tab m3 10lite is in the original version now unusable, so it is no problem if it will be bricked

is an older LOS Version necessary first?
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] Thanh_Nguyen:
No worry, Chris,

I am also very new and I had done the update in 3 hours on my device which is not unlocked bootloader before.

Just follow below 3 main steps:

1. Unlock Bootloader which cost 5$ using 3rd party service

[GUIDE]-[Unlock Bootloader+TWRP+Root] Huawei MediaPad M3 8.4 [BTV-W09, BTV-DL09]

The official Huawei bootloader unlock program has been shut down! This guide describes how to use DC-Unlocker which will cost you about $5 USD. I am NOT affiliated with DC Unlocker in any way!!. This is simply the cheapest and easiest method I...

2. Install latest TWRP

3. Install latest ROM (LineageOS 17.1)

I want to give my tablet M3 Lite 10 to my brother and i want to clear all personal data. I'm on the latest LOS 17.1 (15.10.2022). What happen if in twrp i format data and reflash the latest LOS? I risk to brick the tablet? For every device that i've sell or i've donate i've make this and everything has worked well. Thanks for your help

TWRP 3.2.0 worked

OK - i have a little problen....

After flash into BAH-L09 twrp 3.3.1-0 tablet stuck into splash screen twrp....

Could you give me any direction?
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
If you will read absolutely everything written in the OP (Official post) you will realize that there is also this necessity, to be in a certain version of Android (LOS)
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
Unfortunately, this tablet is one of the most difficult to control when installing custom ROMs.... that's why I mentioned step by step in each OP what must be strictly followed both in the official posts about TWRP and about LOS! All you have to do is read the entire OP very carefully, and strictly follow the steps there, just one step omitted/wrong and your tablet will start giving you problems!
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
New Update !!!

There is a new update in OP, and this one comes with the last security patch from February 2023, of course it also brings all the improvements brought to this ROM ( LOS 17.1 -Android 10 ) until this date !

EDIT:

In most of cases if you use the older version without modifications you'll be able to update by dirty flash !
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] z172839:
Hello, I swiped into recovery3.3.1-1 and then into LineageOS-17.1, which showed that the signature verification failed and the ROM could not be swiped in. What's the problem? Please help me have a look, thank you!
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
z172839​

You shouldn't enable signature verification into twrp before to install this ROM !
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] z172839:
Error prompt on the picture appears when swiping in and closing signature verification
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
before installing this new update you were definitely on Android 9 - Lineage OS 16.0 as mentioned in the OP at the bottom?
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
z172839​

Please take a look here too ! This tablet is not as simple as other devices when it comes to installing a custom ROM... that's why you have to read absolutely everything from the Official Post (OP) to understand and follow the steps strictly, no matter if it's TWRP or LineageOS... otherwise your tablet can very easily become unusable, and the responsibility belongs entirely to you !

Thank you very much for your understanding!
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] frankielin:
dirty flash of latest release.. Everything ok!! Thank you surdu_petru for the update!!!
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] z172839:
OK, I changed a ROM package and successfully swiped it in. It should be that the ROM does not fit or there is a problem with my own operation. Now I have successfully started up. Thank you for your guidance! Thank you again!

Hi;

I don't have any objections about the version twrp. In my case worked version 3.2.0. I also was used this version to install your version of lingerie os 17.1. All work perfect and really quick.

I will say more. can't wait for you to pick up version 19. You're doing a really great job. I thank you for that very much.

Hi, i did not read all the 38 pages of this thread but i have a question. I followed all steps. Installed LineageOS but it doesn't go further then the logo with the (. What to do? I can reset it or anything.

Now i'm a little bit further. It boots into an error on encryptie. it won't even boot in TWRP. I do see the twrp screen and it loads, but during loading it reboots. any idea how to solve this?
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] frajer:
Which version of device?

Which version TWRP was installed?

For example I have Mediapad M3 Lite 10'' - codename BAH-L09

On my device property works only twrp 3.02 (see my posts upper) Each different version twrp makes over and over bootloop.

My advice install again diffrent version twrp using ADB (and remember that first boot maybe takes a long time). Here is post how to remove data encryption: https://xdaforums.com/t/fixed-how-to-remove-data-encryption-in-twrp.3757595/
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] mib1982:
I have been using this ROM for several versions. However, since the latest update, I am not able to do any updates or installation of any apps. It says I should get rid of some of my apps to free up some space.

I removed the external SD card and reset the device to factory defaults.

After setting up the device again, the problem persists, any ideas?

Edit: Nevermind, works again now, I had to clear the internal storage via TWRP to make it work. After setting up the device yet again, the problem is gone.

Thanks for the good work with this ROM.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] fschade:
TWRP 3.2.0.0 as mentioned in the instalation guide.

i don't know the code name but i know it's a mediapad M3 lite 10

Currently everything is wiped, i only have adb but it won't boot into twrp.

If you any tips how to get it back into booting into twrp. I now only get the EMUI recovery menu and it won't work because it want to update but it won't update.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] fschade:
Update: I erased everything with "fastboot erase system".

Used TWRP 3.3.1-0 and installed LineageOS 17.1 succesfull.

After that i installed TWRP 3.3.1-3.

It starts loading the new twrp but half way it reboots.

Any idea what i can do to get GApps?
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] fschade:
I found the answer. Sorry! it was just al lot of reading and clicking true:

- with your device in bootloader mode ( and after TWRP was installed by : fastboot flash recovery C:\twrp-3.1.0-0-eva.img, in your case ) you should make three operations at the same time :

* press & keep pressed Volume Up

* fastboot reboot

* disconnect the USB cable as soon as possible !

I often use my tablet for watching the MLB app, but that now requires Android 8, and I was running stock EMUI Android 7. I was about to buy a new tablet, but decided, to give this a try.

I don't know much about this stuff, but I got LineageOS 17.1 and Gapps Nano installed. Now the MLB app works.

(Idk how many times I thought "I bricked it. Not getting X to work. Time to throw it away" It's a bit maddening. Just keep repeating the same instructions over and over and eventually it starts to work)

However, one step forward, two steps back. Netflix and Hulu don't work. I don't use these often on the tablet, but if its possible to run these apps I'd love to know how it's done.

Upon googling I see it has to do with Google Play Certifcation? Hmm.. I registered my Android ID with "Device Registration" I don't see a change. Maybe I misunderstood how that works.. Idk.

Other searched lead me to Hide/Magisk, I think at that point it all gets pretty shady. I'd rather not bother if that's my only way through.

Hi @surdu_petru .

I'm finally getting a new tablet as the now ancient MediaPad is just too slow for heavyweight modern websites and the battery is finally starting to fade, but I wanted to check in here one last time to thank you for all the hard work you've done for us by building and maintaining these ROMs all this time.

You've kept my tablet up to date and useable way, WAY, WAY longer than Huawei ever bothered to do. A whole 4 years more!

So, good bye and thanks for all the fish :)

Thanks for the new update. Did a dirty flash. My normal apps are working well. Banking app works well include german PhotoTan app..

A little problem is still there with the bromite browser: video playback stops after a few seconds and then it starts again for a few seconds. No problem in duckduckgo browser.. The bromite problem in the previous LOS 17.1 was no useful playback. Only voices but no picture.

Thanks sudru.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
Thanks for feedback, but I guess there is a new issue and is closely related to Chrome browser video fix !

Unfortunately the fix for video play in Chrome, break the playback of some videos in the gallery - as a very easy check , you are not able to play your video recorded by camera !

On the next update I'll revert the fix of video play in Chrome browser, because the issue is not in LineageOS nor on my source ... we should wait untill Chrome and other browsers will be properly updated to Android 10, as there are a lot of browsers like Microsoft Edge where the issue is not present.

Did you test the Installation of V4A. I tried to install Viper4Android like in LOS 16 but had no success. After installation oft V4A tab reboots in bootloader. So i had to play back my backup to get tab workin' again.

Will be thankful for any help, because music sounds bad. I will try clean install , if time allows. But this moment i need tab for my work.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] ossizwei:
Viper4Android

Tried different ways to install V4A on BAH-L09 with clean install:

1.Normal Installation ends up in android bootloader screen after V4A driver installed.

2.Magisk modul in magisk 20.3 is too old. After install and reboot in Magisk the tablet freeze on boot warning screen.

Then I read on the forums that the problem of installing V4A is known. So i tried a workaround. But

3.a beta modul for android Q installed with magisk didn't work too.

At the moment there is no way to correct the sound with V4A. Its not a special problem with this great rom created by surdu. I think we habe to wait for a new V4A build.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] mogwai71:

I ran into the same issue with V4A on my CPN-W09 with this rom as well as the Pixel Experience rom. I did some digging and found the following thread:

https://xdaforums.com/poco-f1/how-to/guide-to-viper-android-10-custom-roms-t3996829

I tried it out with this rom and it worked. Maybe it would work on yours as well.

I really need help to continue getting my BAH-W09 back in a working state.

I followed the op and can only get the lineage boot logo. Can't proceed no matter how many hours I leave the tab booting. I used Multi Tool to unlock BL and install twrp.

1) Unlocked bootloader

2) Install TWRP 3.3.1-1

3) Flash Lineage 17.1 from external SD - many many red errors here :(

I retried the same again this time using TWRP 3.2.0-0 and Lineage 16.0 with exactly the same result as previous.

Now I'm stuck trying to get out of this. I wanted 17.0 flashed but now I'm even struggling to boot to TWRP with a 1/20 chance of getting it booted. :crying:
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
Hi!

I guess you didn't format data into TWRP, this is the first step in order to be able to install LOS.

If you already formated data, please try a clean install, so into TWRP wipe all apart external storage, and be sure that you use the new twrp for Android 10/Q , otherwise you'll got in bootloop.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] djnield:
Thanks, I'm so stupid :eek:

I literally just managed to get 16.0 successfully installed. Going to try 17.0 now :good:
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
Good !

If you'll not install the last twrp for Android 10 than you'll not be able to install GApps into LOS 17.1 .

Good luck ?
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] djnield:
It's all good now. LOS 17.1 is successfully installed now. Can't believe you made Android 10 with latest security patch for our tablet :good:

I was on v7 and patch from July 2018 until today.

I made a backup in Hisuite before this but I guess I can't use that backup under LOS?
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
I never used a backup, so you can try it ... but I guess you'll end up with a boot loop :)
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] djnield:
I only wanted to pick and choose bits. But hisuite requires something called HDB running on the phone. I'm assuming this must be some huawei thing then as its no longer there after flashing [emoji848]
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
You shouldn't waste your time with this backup because I don't think it will work ... if you take the backed up to Android 7 and you want to restore it to Android 10, then the chances are almost null, you could only restored properly on Android 7 but there is no custom ROM Android 7 for our tablet.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] djnield:
Got ya. Setting up as new right now.

Thanks for breathing new life into this [emoji3]
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
You are welcome :)

And HDB it's the same with ADB but implemented by Huawei ... so the custom ADB service ( HDB ) was removed in all custom ROMs, because there is no way to make it him working properly !
