Ok, registering the device's android_id with Google worked, the warning went away and everything works fine. Also upgraded to nano gapps without problems. Thanks a lot to @surdu_petru for giving this tab a second life, really appreciate your work!

Does the camera not work at all or only the camera app?

Can I use, for example OpenCamera?
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
Only on LOS 16.0
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] dima-82:
Good evening and thank you for the ROM.

Appreciate your work!

I played around with the ROM it the whole weekend. An now I am happy with the result :)

Was situation:

- BTV-W09 with C100B302 (Android 7)

- TWRP 3.0.1-1 (Greatslon mod)

- Magisk 19

Is now:

- BTV-W09 with LOS 17.1

- TWRP 3.3.1-1

- System partition unmodified (still 2GB)

- Magisk 25.2 with Zygisk enabled

- LSPosed 1.8.6

- microG Revived (Magisk Module)

- FakeGapps (LSPosed Module)

- MagiskHide Props Config

- Universal SafetyNet Fix

The system is running stable and if you consider the old processor, it's not doing too badly.

Play Store is working. All purchased apps are working. Licenses could be restored without issues.

SafetyNet passed! With the modules above. Device fingerprint is from Xiaomi :) There are not Huawei tablets with android 10 in the list available.

- GPS Working.

- I don't use the camera on the tablet, but I tested it, and it is not working :(

- Home button not working as button, only as fingerprint scanner.

It would be great, if you could continue development and maybe fix the camera in the future.

Thanks again!

Hi @ all,

I have this Mediapad BTV-DL09 too, running at BTV-DL09C100B311 / EMUI 5.0.4 / Android 7.0 / 32GB internal / 4GB RAM.

Because I hate this - I am a noob, can someone help me - I read all the 61 pages here and the Guide to unlock the bootloader too.

To practise the things written here, I used an old Telekom Puls (Alcatel One Touch) running on Android 6, unlocked the Bootloader, installed TWRP and after that LineageOS 14.1 together with gapps pico, successfully ;-)

now I feel well prepared to do this with the Madiapad ;-)

Let me ask one question before I start:

When I use the pico gapps version, I do not need to expand the System Partition to 5GB, because there is enough space to go forward right?

Because there will no security updates in the future for the android 10 version, the version from "update security patch level : October 5, 2022" - posting 1176 - page 59 - 16. Oct will be the last one for this LOS 17 branch right?

Are there any plans to move to LOS 19?

while reading all the postings here, surdu_petru wrote that LOS 18 will never be available.

First step will be unlock the bootloader with DC unlocker (adb and fastboot environment is working, DC Unlocker will get all the Data which I need) and install the TWRP >> DONE ;-)

I am a litte confused about the next steps, in the OP

Install the new TWRP 3.3.1-1 ( needed for Android Pie/Q )

Reboot to TWRP 3.3.1-1

Perform a clean wipe for the first install

wipe all ( into advanced wipe menu ) apart Internal s torage & Micro SD card (if available )

starting with 14/05/2022 you can increase the system partition to 5GB from here

Flash the latest build available

optional flash ( always the last available packages ) GApps

Reboot

what about the:

Select Wipe then select Format Data

This will format the table and remove the encryption (VERY important step)

as it is written on Page 35 - #681?

here in this little video there is no format data too
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] tim_h:
Yes, pico gapps works with the standard 2 GB system partition. (Nano gapps does not fit!)
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] S8_Phone_Fan:
thanks, does anyone can answer the latest question about the steps to flash the lineageOS?
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] Jerry Lv:
Though i think arrowos is better but thanks surdu_petru for bringing my old guy back to life
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
No, I will add a new update as soon as I have some more free time
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
the steps to follow are very clearly described in each OP, be it TWRP or LOS
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
New Update !

I'm happy to come with a new update of this custom rom ....

Changelog :

new security patch level : February 5, 2023

come with all improvements brought to LOS 17.1 at this date

Downloads :

For devices with 2Gb System partition : LineageOS-17.1-BTV_2023-02-25.zip md5 : e9b79f588dd7be85e4a9773f9468b7d5

For devices with 5Gb System partition : LineageOS-17.1-BTV_2023-02-25.zip md5 : fef80bebb7fc3e2f4bca259a5a41c269

Boot image for Wi-Fi only devices : boot_w09_ten_2023-02-25.img md5 : 2d23b58d7aed7ea9b7b8b66410a32edf

I suspect that the installation process is well-known to you (the easiest for those who just update from the old version, a dirty flash is enough)
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] Me,You,and Daigorou:
I recently use this ROM without installing Gapps.

My device works more comfortably, and uses lower CPU clock speeds more often than before.

For apps, we can use the Aurora Store without any problems, except for Gmail, etc.

However, if you want to install Chrome and Webview, you need to install the Trichrome Library beforehand; download the one from apkmirror that matches the version numbers.

microG is not necessary.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] dima-82:
Hey guys,

yesterday I realized that bluetooth is not working on the October 2022 release. The bluetooth app is always crashing. Does anyone has the same issue? Resetting the app (clear data of it) didn't solve it. Tried even to diasable all Magisk modules.

Will update to the latest release today. Hopefully BT will work then...
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] Me,You,and Daigorou:
I learned a little Java to fix the auto-rotate bug that happens on BTV-L0J. However, I can't determine what is causing the problem by looking at Logcat.

What language did you use when you have fixed these problems?

C++?

Linux kernel?
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
depends on case by case, you can use Java, C or C++ ... linux kernel is indeed C++ ... if you tell me how you solved your problem, maybe I can add it directly to the ROM so that you don't have to repair it after every update

EDIT : I don't have your tablet so I can't replicate your issue, on my tablet there is no issue about auto rotate !
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] S8_Phone_Fan:
ok I did it like this with the newest Secury Patch:

StockRom is still installed, but Bootloader unlocked und TWRP installed

boot into TWRP

wipe > format data > yes

reboot into recovery (install TWRP new after format data > yes)

advanced wipe > apart Internal storage & Micro SD card

install the lineageOS zip Image & gapps pico (with add more zips)

After that Wipe "cache / dalvic"

choose reboot and yes -> install TWRP new after flash

After starting up lineageOS, read the Android ID, went to my play store and register it.

After ca 20 Min the Playstore is working!
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] dima-82:
Do I need to reflash boot image on the WiFi version, IF I UPDATE?

If yes, do I need to repatch/reflash Magisk?
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] dima-82:
Thx! Update worked without problems.

GPS working. Camera still not supported.

And BT is crashing again.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] Me,You,and Daigorou:
Yes, this issue must be solved by the BTV-L0J user.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] S8_Phone_Fan:
just a quick question about the Google registration. I did this yesterday, read out the Andriod ID, add it to my account. Wait some time and yes, it is connected.

I installed about 15 Apps successfully from the Playstore ;-)

After some hours, I open again the Playstore and get now allways the message "the decive is not certified for play protect"

I checked the ID again, its still the same and its still in my google account.

Then disable playstore & play Dienste, reboot and enable it again but no change at all.

Because it was already working, I am afraid how can I get out of this?

Flash it again and get a new Android ID?

Thete is only the close button available, nothing more.

[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
Try once again but this time you need to reboot your device after you signed into account ( wait about 10 minutes before reboot and after signed )
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
I'll check today later
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] S8_Phone_Fan:
the google account is still added in my device, so I am singed in. I did this (your sugguestion) already this morning.

Reboot my device when signed in. There was no change until yesterday evening.

Maybe I remove the google account, reboot it, add it, see whats going on and reboot again with added account?
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] dima-82:
Thank you!

If you need any logs, please tell me. Will be happy to support.

Edit:

I deleted some apps, when set up the tablet. Could one of those missing apps cause BT to crash?

Yes, maybe it would be better if you can try to flash again, install also Gapps, signed on Google account, wait 10~15 minutes, reboot your device, wait again 10~15 minutes ... It's always working for me in this way

Edit : sometimes you need to wait a bit longer after you reboot your device .
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
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 :
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] S8_Phone_Fan:
ok again the same procedere, format data and start a completly new installation, this time I used an old 2020 opengapps nano package. after first boot, I got the same messages about a not certified device. Read out the Android ID - its a new one. Add It to my google account and after ~ 2 Min the beeping sound has gone. I saw an upgrade of the playstore running. Now I restore all apps from my phones backup via google. I opend the playstore several times, all without any problems.

I hope this will be stable now - cross the fingers
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] S8_Phone_Fan:
and again after some hours the same behaviour. The Playstore tells me, "the device is not certified for play protect".

Screenshot above. because I used a different GApps version, could it be a problem with the latest LOS Version?
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
if you think that your problem is from the last update, then you can try to install an older version & sign here into your Google account and then update ( dirty flash will be enough )

Thank you very much for your donation!
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] S8_Phone_Fan:
a dirty flash back to the last Version produces a very buggy device. Because I was singed into playstore before I start the installation, the device came up again signed it. When I press the playstore button, the result is the same (still not certified).

Now I install the backup which was created before the dirty flash [done].

Maybe I try it a third time from the scratch, get a new Android ID, read it out of the device and switch it OFF.

Now go to google and register it, leave the device 3 days off and check again.

I don't have any other idea ;-(
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] BodingisanAndroid:
I have the same exact issue but it seems you can still push apps from the web. Updating doesn't seem possible without uninstalling then reinstalling. I've tried several fixes as well to no avail. My device is correctly registered with Google Play and I do not get any warnings, however I simply cannot get past the Play Store error.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] rapandroid:
Hello everybody. I have tried to install LineageOS-17.1-BTV_2023-02-25 but I think that I have bricked my Huawei Mediapad M3 8.4 BTV-W09.

It was with Android 7 and EMUI 5 and the bootloader was unlocked by dc-unlock. After I installed the new TWRP 3.3.1-1 and until there everything went well.

After I downloaded LineageOS-17.1-BTV_2023-02-25.zip and I copied it to the micro SD card and I installed it using the TWRP but I think that it didn´t work. Before installing LineageOS I have performed advanced wipe everything except sdcard and internal storage.

I rebooted the tablet but it doesn't start with this new operative system.

After this it went to the Huawei eRecovery screen but I neither can't to restore the system in this way.View attachment 5852941View attachment 5852943View attachment 5852933View attachment 5852935View attachment 5852937View attachment 5852939
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
Please, if you try to install LOS for the first time, format data under TWRP it's mandatory !
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
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 )
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] rapandroid:
I also did it and tried everything but there is no way
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
You have this error into TWRP because /data wasn't formated properly, or maybe you didn't restart your device after /data was formated .... you can ignore the rest of the errors, they do not affect the installation process in any way...

it is also mandatory to install the boot image required for your device, because you have a WiFi tablet and not one with 4G/LTE

Try again, I'm sure you missed something, otherwise it would have gone without problems as it works correctly on absolutely all devices!

EDIT : I think you made a mistake: wipe /data does not mean the same thing as formatting /data
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] rapandroid:
I understand. So, I am going to wipe all data except sdcard and internal storage, after I will format data. After I will install boot wifi image and to finish I will install the LOS. These are the steps that I have to follow correct? Thanks in advance for you help.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
Firstly you should format data then reboot device again to TWRP, wipe all, install LOS and the last thing you should do it to install boot.img for your device . if you did these steps in a different order, it is normal to have issues.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] rapandroid:
I have followed the steps exactly as you have said but I get this error installing LOS. View attachment 5853393
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
it is normal to have errors as long as you are not paying attention to what you are doing... if you look more carefully there are two versions of LOS, one for the System partition of 2Gb and one for 5Gb... now I leave it to you to document yourself reading the old posts where you will find out which version of LOS you need ... in the future try to be more attentive to what you read and what you do on your device ... otherwise you will only have problems that are strictly due to you
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] rapandroid:
I know that the problems are my fault and that is why I am asking help. I guessed that my tablet was system partition of 2gb and I tried to install this version. Also I have tried to install the 5gb version but I got the same failure. Thank you for your time and help.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
If you didn't modified stock system partitions which has 2Gb you should flash LOS appropriately otherwise flash LOS for 5Gb System partition. I suggest you to try once again from scratch, this time following the steps in order that I told you in the post above, and flash LOS appropriately to 2Gb System and finally flash required boo.img for your device, good luck!
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] S8_Phone_Fan:
I did the first install this way: (2GB BTV-DL09)

boot into TWRP

wipe > format data > yes

there is a message, the device should be rebooted to use the /data partition (because of the old encryption)

choose reboot into recovery > another message came up, TWRP is not installed (maybe because of formating /data), comfirm to install it before rebooting

device came up freshly rebooted into recovery

advanced wipe > apart Internal storage & Micro SD card

back to install, choose the Image & gapps pico or an older 2020 nano version (with add more zips)

if its installed > Wipe "cache / dalvic"

Reboot ... it takes some time to boot into system

The device comes up beeping and complaining its not certified > read out Android ID and register it in your Google account.

Wait some time (you don't need to add your Google account in the device) and you will see an upgrade of the playstore app. Beeping will disappear > add your google account in the device and install apps.

Hope that it will work 24h later ;-)

you need to install the boot.img for the Wifi only Version, don't care about the /3rdmodem error. this is ok
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] S8_Phone_Fan:
thats interessting, so I am not the only one with this behaviour ;-(

Which LOS version you installed - was it the "New Update February 2023 : LineageOS-17.1-BTV_2023-02-25" or an older one?

Which GApps version you use? Have you tried it with Magisk?

There is a easy way to keep your Apps up date date:

install the "aurora app store" and log in with Google Account. Then you see all you installed apps and can update them.

You can update Chrome, Youtube .... too but you can't use them, because of cerfification problems
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] S8_Phone_Fan:
Thats the way I did it the second time ;-) Formating /data will generate a new Android ID.

Because this not Cwertified Issue is not in LOS 15 & 16 - maybe something needs to be changed in the LOS 17 Image?

I opened a case at google for this, but don't think they could help me
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] rapandroid:
I have tried once again from scratch with 2gb system following all the steps but again I get the same error.

E1001: Failed to update system image.

Updater process ended with ERROR: 7.

I don’t know what I can do to restore my tablet. May be I will use it like a paperweight 😂😂😂View attachment 5853647

Yeah I'm on the latest Lineage 17.1 with pico GApps and Magisk root. I think I'll give Aurora App Store a try. Not having Youtube kind of sucks but I use Brave browser so I can live without Chrome.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] pwochung:
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.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] S8_Phone_Fan:
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?
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] dima-82:
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.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] pwochung:
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.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] Appsony:
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.
