I know how i can fix it, with the additional registration my Mediapad with the "Framework-Android-ID. I added to google- but there is nothing happend on Play Store about 2 ours and many restarts later ....

Hi everyone, recently it took me around 3 days of delay to be registered on the playstore for my BT09.
Long, but it works...

It was working very well before, maybe they changed something ... I have an older backup with Play Store registered and I use that one, then I only update with dirty flash !

Have you tried searching on Google for your issue, to see how others have resolved it ?
Ofc we did.
Google says "Check if your device is on the list of certified devices".
Ok, it is on the list.
Google says "If your device uses a custom ROM, register your device"
Ok, we did.
But still after 2 days...
This is btw Google Play

Ok, in this case you need to wait more ... after you have successfully registered, don't forget to make a backup so that you don't have to wait next time ... the new update can be flashed with dirty flash over this backup, in this way you'll have easly the last update of this ROM with working PlayStore !

This firmware gives the tablet to the second life! Thank you for making it (y)

However, I stood up with a problem: I can not connect the headphones via Bluetooth. When I connect them, the crash of the Bluetooth application occurs ((

Is there a way to fix it?

No, sorry !

You can try to connect and disconnect headphones via bluetooth several times possibly restart the device and headphones, have the same issue first time with my headphones, and finally connected !

Thanks for the answer!
I tried rebooting, turning on and off the headphones and the tablet. But the sound doesn't work.
I will write more about the problem. Headphones are connected and displayed in the settings. But when I press play in any application (music, YouTube, video player, etc.), an error window appears and the bluetooth crashes. You can see it on the screenshots.

I do not know what to do. I'm currently using wired headphones. But I really wish there was a way to fix this.

I understand that the headphones are trying to use the aptX codec, although the tablet does not support it. Switching in the developers menu to AAC does not work (when I select this item, nothing changes).
Is there a way to make the system only connect AAC or SBC?

When connecting other headphones (I borrowed them from a friend for testing) that only support AAC, the sound on the tablet works.

And does anyone have the same problem?
And I’ll add that when I used LineageOS 15.1, the headphones worked there, and the AAC codec was used by default.

Hi, I am wondering whether this ROM support the Treble Project, which means can I flash other GSIs after flashing this Lineage17.1?
Thanks for your reply.

I'm now waiting over 2 weeks. Still not registered... don't wait. Just flash magisk and enable hide magisk inside it's settings. Than hide magisk from google play services, and flash a magisk module named Hide magisk props. Reboot your device and change props using terminal emulator. Than clear data of play store. Your device will be certified and passes safety net

My BTV-L0J had a problem that Chrome freezed. And it has been solved.
To be precise, Chrome is working, but the screen is not refreshing properly and it looks freezing.
After this issue, I had to go to home screen and open Chrome again, then Chrome refreshed the screen normally.

To solve this problem, type chrome://flags in the Chrome search bar and set Android SurfaceControl to Disabled, and RELAUNCH.
This may be an issue that only occurs on BTV-L0J, but if it happens on other models, try it.

I registered my GSF ID at the end of last year, and it took me about two hours to complete the registration. At that time, I went shopping and when I came back, it took about two hours. I registered my GSF ID several times, and it usually took about 30 minutes to register.

After getting a GSF ID, register your GSF ID on https://www.google.com/android/uncertified/ and wait for 5-10 minutes keeping your device connected to the Internet. Restart the device and wait for 5-10 minutes again. Then open the Play Store and log in. It takes about 30 minutes.

Thanks for the tips - it worked for me

Enable MagiskHide for Google Services
Installed MagiskHide Props Config module and used Termux to edit it to Mate 20 Pro - checked that SafetyNet is passed successfully
Clear storage & cache for Google Play Store and then reboot
Finally Netflix appeared using the search

If unable to register a GSF ID, you may have to change a fingerprint...
For changing a fingerprint, I think Aqibjd773's post and evilhomura89's post can help you.

The connection between bluetooth and speaker is unstable on my device as well.

    Hey, surdu_petru what do you think, will you be able to do any more updates for this ROM?
    Unfortunately, official support has ended for LOS 17.1 Android 10, which means there will be no more security patch updates.

    Since @accerian has found a solution to enlarge the system partition so that we can later install any of the GApps packages, I will be back soon with a new update.

    Hi !

    New update will be here very soon !

    Will include the latest security patch from May 5, 2022 and system partition of 5GB in order to be able to install any GApps !

    New Update Of LOS 17.1 !

    There is a new update of LOS 17.1 into OP for our device !

    Changelog :
    • updated system security patch level : May 5, 2022
    • system image partition increased to about 5GB to fix installation of any GApps

    Before installing this new update please manually modify the system partition size using this tutorial !

    There is 2285MB free on system partition after I installed the mini version of GApps !

    Surdu, I don't know if it is helpful, but there is another ROM installation method that uses flash-all.bat via fastboot instead of TWRP/Recovery that may be useful. ProtonAOSP and others use that method. I'm wondering if it might help us make the jump to 18 ?
    I don't think it's a recovery issue, I tried to install LOS 18 on my device, but unfortunately I didn't find a way to update graphics blobs to Android 11 in order to be able to boot ! Not to mention the other drivers that also need to be updated to Android 11, and I don't see any solution for that at the moment.

    To detail a little:
    There are some things that are harder to access / (controlled) because they became dynamic in Android 11 compared to Android 10 where those things could be controlled through a file - this is the main reason why no driver in Android 10 is recognized in Android11 (and a solution is very hard to find and involves more of a hack in our case, but unfortunately as I said, I do not know at this time how I could do it)

    Sad news. lineage security patch updates are short.🥺

    Reporting Bugs
    • DO NOT Report bugs if you're running a custom kernel or you installed Xposed
    • Grab a logcat right after the problem has occurred. (Please include at least a few pages of the log, not just the last few lines, unless you know what you're doing.)
    • If it is a random reboot, grab /sys/fs/pstore/console-ramoops and /sys/fs/pstore/dmesg-ramoops-0. (Do not bother getting a logcat unless you can get it just before the reboot. A logcat after a reboot is useless)
    • If the problem disappears after running "setenforce 0" from a root shell, grab /data/misc/audit/audit.log
    Remember to provide as much info as possible. The more info you provide, the more likely that the bug will be solved. Please also do not report known issues. Any bug not reported in the bug report format below may be ignored.
