[ROM][10.0][ LineageOS 17.1 - For Huawei MediaPad M3 8.4 ][ Update 2023-02-25 ]

[pwochung]

yes, it seems you didn't understand me correctly... see what I wanted to say (in more detail) :

go to TWRP and format the data, reboot the device in TWRP, wipe everything under advanced wipe ( apart internal storage and microSD ) .... install an older LOS where you had no problems with registration in the PlayStore, install the Gapps package ... reboot to System .... try to register at PlayStore, following the steps I described in the post above .... later you can update your device to the last available version of LOS only through dirty flash ( does not require any wipe before to flash LOS ... just wipe cache & dalvik after LOS was installed ... also you don 't need to flash once again Gapps )

My device is BTV-W09. I tried the latest version and LineageOS-17.1-BTV_2022-02-20.zip version (no update to the latest), both got "the device is not certified for play protect" after several hours.

I expect you read out the Android ID and registered it at Google?
Your device came up at the first boot beeping and telling you the whole time its not certified?

When I add the Android ID at Google this behaviour changes 2-5 Min after registration, the Playstore gets an update, the beeping is gone and the messages too. Have you seen this or is the device the whole time beeping?

I'm very sorry but I really don't know .... just tested BT on my device and it's working good in the same way like before ... I know that BT it's not 100% working like on stock EMUI firmware, there is still some issues with connection and with some devices , but unfortunatly I'm not able to solve them .

I leave here some screenshots from the test I did at BT on my tablet :

Just did a factory reset and clean reinstall. BT is working.
Will now try to find the root cause for the crashing...

Edit: F***, it took me 2 hours, but I have it

My debloating, hardening, you name it, caused it.
I deleted everything, I don't need on the tabled. On of the system apps was contacts and contacs provider (com.android.providers.contacts).
If you delete (uninstall via adb) the contacts provider, bluetooth app will crash.

Sorry, I missed some explanations. In both cases, I registered and got Google to work properly initially. But I got the message "this device isn't certified" after some hours.

hello.

I installed Lineage 17.1.

Some problems could be solved through alternatives.

But, GPS doesn't work perfectly.

GPS usually works fine.
After power saving mode, GPS does not work.
And sometimes the GPS just does not work for no reason.

In this situation, re-enable GPS by rebooting.
But I don't know when the GPS will suddenly stop working. (Mostly I'm driving a car)
It is big problem

I would like you to review and fix the GPS part.

Anyway, thank you very much.

Good morning Petru. First of all thank you very much for all the work that you have done.
I finally got to install LineageOS 17.1 using another microSD card, but now I am with the problem of Play Protect.
So I decided to format data, reboot TWRP, wipe all except internal storage and sdcard and install LineageOS 16.0, Gapps pico and bootwifi9.
I logged with my Android ID without any problem and Play Store worked fine.
After I did that you have said in previous posts and I flashed only the LineageOS 17.1 and after install I wiped cache/dalvick without installing
Gapps. Until here everything is okay but when I reboot the system it gets stuck in the Lineage logos. Thank you in advance

Yes. It happened to me several times. Now I'm come back to 16.0 which is smoother than 17.1.

Hey guys.
maybe my experience of the last days and weeks can help somone:

I am running Lineage 17.1 (February release) on my M3.
I did not increase the system partition. So eventually I could only install Open GApps pico (which is fine for me, since all other google apps can be installed as user apps from play store).
For all other Open GApps variants with more apps the system partition needs to be increased to 5GB. (instuctions see first post from @surdu_petru).

In the end I didn't use GApps. I installed microG Revived on the M3 to get Google Services. Unfortunately to run apps with in-app-purchases it was necessary to install a modified play store apk. Additionally for signature spoofing Magisk's Zygic, LSPosed and LSPosed module FakeGApps were required. After some hick-ups with the play store registration and and login in my google account I got it running.
In-app-purchases worked, but I could not install purchased apps from play store (e.g. Titanium Pro, Nova Prime, AFWall+ Unlocker). Aurora store solved the issue.

That solution contained to many workarounds and I realized that my device was slow, laggy. After a restart everything was fine, but after a while again the same issues.
Furthermore the update of the play store was not possible. The modded version is 20.x.xx, which must be already a couple of years old.

So I started to look for a better solution.
I found this XDA article:

Download and install the latest GApps: Open GApps, NikGApps, FlameGApps, and more

Looking to install a custom ROM? Need the right GApps package for it? Here's how you can download and install the latest Google apps.

www.xda-developers.com

I began to test GApps Magisk modules.
- MagiskGapps: Does not work, since it supports Android 11 - 13. LOS 17.1 is Android 10.
- LiteGApps: Could be installed but didn't work. Google Play Services crashed permanently.
- BiTGApps: Works!

So finally I found for me a clean solution. BiTGApps Standard with the minimal required component to have google services. Play Store was updated to the newest version. I got rid of microG, LSPosed and many modules. System partition need not to be modified, even if you select a more comprehensive GApps package.
Signature spoofing is not necessary. Play Store shows "certified". I am happy so far...

BTW: For SafetyNet pass still Magisk and the two known modules are required.

I had this idea (try a different GApps Version) too, because I have a Galaxy S8 SM-G950F with LOS19 running GFlame Apps and a not certified Play Store - which works propper since more than a year.

So I did this yesterday, BiTGApps Standard, LOS 17 Februar Version, Format Data, install both zips. Booting the first Time, device comes up beeping, read out Android ID, register it at Google. Get an Upgrade of the Playstore App.
The Playstore shows always "not certified" but I could use it. I switched it off and back on this morning and NO surprise ... when I open the Playstore App, I get the same as before twice: "the device is not Play Protect certified".
I have a BTV-DL09 LTE Version, whats your one "dima-82"?

nevertheless I discuss this more than one week with Google Support, because the BTV-DL09 is on the official supported device list of Google

https://storage.googleapis.com/play_public/supported_devices.html

they told me now 2 times .... this Unit is not supported. Seems when someone complains about Huawei - the standard answer is "not supported - go to Huawei".

 

[dima-82]

I have a BTV-W09.

I didn't register any Android IDs at Google.

Maybe one of the following things can help:

- I have Play Protect Scan disabled.

- To pass SafetyNet I have the two Magisk modules MagiskHidePropsConf-v6.1.2 and safetynet-fix-v2.4.0 installed. As far as I understand the first passes the CTS profile match and the second the basic integrity.
To pass CTS it is not enough to install the module, you have to configure the props.
Since there is no official Huawei MediaPad M3 with Android 10 on the market I selected another device with Android 10. In my case it is a xiaomi pad 8 or so. So does Google see my device now

Thanks dima-82, that fixed my playstore problem ;-)
I used a Samsung Tab S6 fingerprint running Android 10, now my Playstore is certified.

I've been tying to get the certification to work, it worked after submitting the device ID to Google, but it was blocked again next morning.
Using the Tab S6 fingerprint worked for me, thank you.

For anyone who needs a how-to:
- Install Magisk in TWRP
- Follow THIS guide, steps 1-19
- Install Terminal Emulator on your device
- In terminal type props -> edit device fingerprint -> pick certified fingerprint -> change to Samsung Galaxy Tab S6 -> reboot device
- Follow the rest of the guide starting from step 21
- Your device should be certified now.

Hello surdu_petru, first of all i want to thank you for your work and also hello guys,

i installed this custom rom a while ago and everything works fine so far. Thanks for that. However, there is one problem that I haven't been able to solve so far. When the tablet goes into standby/sleep mode, WiFi stays active, so it stays permanently connected to the router. This circumstance naturally has a negative effect on the battery life. I didn't find anything in the settings. Is there a solution for this?

 

[mcarosh]

Hi...
First of all big big Thx for your (surdu-petru) efforts to keep this Tablet alive
I have a small question to this (or any other except stock Rom. Is anywhere the package

GitHub - LineageOS/android_packages_apps_FlipFlap

Contribute to LineageOS/android_packages_apps_FlipFlap development by creating an account on GitHub.

github.com

included?
This is for use with a "smart flip cover"

Does Gmail work for you? I can't add an account at the beginning, because the one registered is not listed. All the other Google apps are working fine.

I chose S4 Tab for fingerprint, but I don't think that's the cause of the problem, maybe OpenGApps is buggy.
