You are awesome and thanks for all your hard work!

The last release and latest kernel have been rock solid. I really enjoy using this old device again.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] Vesko01:
Well let's say he meant to ask if you are not planning to implement this feature or it simply isn't possible. :o

Also, thank you so much for your hard work and I cannot wait for Android Pie and hopefully 10 in the future!
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
No one found that Wi-Fi hotspot does not work :confused:

EDIT:

Ok, anyway it doesn't matter, I see it never went right :(
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] orangpelupa:
Hi surdu, thanks for keep updating this nifty tablet.

btw i have a very noob question: why go to android 9 instead of directly jumping to android 10?
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
Because it's more easily to fix the eventually issues on Android 10, if we have a working Android Pie ... and for the same reason I started with Oreo, because it's almost impossible to switch directly from Nougat to Pie :)

Edit:

Ok, I could start working directly from stock Nougat to Android 10, but this mean that you should wait almost 1 year, without any intermediate releases from my part. This is not a viable solution because your tests help me a lot on developing the Rom & kernel and at the same time all users can join to a new update. You'll see later that there's is no expensive difference between Oreo-Pie-10, like was from Nougat to Oreo.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
Hi !

Today I started working on Android Pie, LineageOS 16.0 !

Let's see how long it will take until we can use it like LOS 15.1 and also if I'll be able to make it as stable as LOS 15.1 :o

A new thread with LOS 16.0 will be here as soon as I'll be able to make a beta version for test !
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] qxdafan2020:
I think all Your work is really great and admirable. I have exactly the Huawei MediaPad BTV-DL09C100B311. This suits seemingly very well and I have already this TWRP app installed and did plenty of additional steps in the EMUI 5.x that are not listed. I bother how to put the parts together. Unlocking this EMUI in the Developer section and then update to Android 8. But how? Android is not the drivers that is HUAWEI. And all the other updated the normal path. I read about keys and allowances further than Settings > Developer options > OEM unlock. Systems updates are still available from HUAWEI. That is not disruptive.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] Vesko01:
Hi guys, can anyone fill me in on how I can fix the problem with apps missing from the Play Store? I'm talking about apps that were available before with the stock android 7.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] friedsonjm:
Which ones?
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] tek3195:
There are quite a few that check for play store and won't show in a custom rom. Use Aurora store for those that don't show in playstore. Same apps from same servers.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] martymcbro:
You have to use magisk to fake the device fingerprint and pass the SafetyNet check. Then you have to clear data from Playstore and Play Services Framework to make the apps reappear.

For me this made Netflix appear. My banking app is still missing.

See this discussion:
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] tek3195:
A simpler solution is Aurora Store and it installs Netflix no problem, don't know about banking apps, don't use any myself.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
The last INFO about LOS 16.0 before to open a new Thread about it !

I spent two days until I managed to make LOS 16.0 to successfully boot on my device and also two days to find a hack for audio hal ... and now I have sound enabled on LOS 16.0 !

Yes, almost all doesn't working, apart touchscreen, Bluethooth and now audio !

Until the first release of something like the Alpha test, I think I need two or three more weeks.

In the meantime I'll return with an update to LOS 15.1 in a few days !
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] sergio_sant:
Nice job! Thanks! Do you think we will have gestures in Android 9? So we can get rid of the navbar
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
Unfortunately this option is available starting with Android Q, at least on LineageOS !
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
Hi !

I'll create a new thread for LOS 16.0 soon with a experimental release ... we need this topic in order to move all discussions about Pie there and let LOS 15.1 clean :o
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
New Update of LOS 15.1 !!!

Hi !

I just released a new update of LOS 15.1 for our device - like always, please check OP for download link :)

Changelog:

- update security patch : November 5, 2020

- updated kernel to Android-Linux-Kernel : 4.4.114

- fixed off mode charging

- fixed one more time tablet layout mode :

* tablet will stay on landscape mode after unlock if previously was on landscape mode

* fixed show label of apps on landscape mode

Warning :

- the adoptable storage ( format sdcard as internal storage ) not yet fixed , so you need to use the older workaround ( eject microSD when device boot - and insert it later after boot )

I hope to find a solution to this problem in the near future !

The next update will be here next month with the new security patch for December !
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] friedsonjm:
Downloaded, wiped Dalvik & Cache, installed ROM and Boot image... when booting to system, got stuck on 'Your device is booting now.' Wiped everything except SD Card, reinstalled ROM and Boot image, still getting stuck on 'Your device is booting now.'

Thoughts?

EDIT: Restored previous version from TWRP backup.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
On BTV-DL09 all it's working like expected, I don't know what could be on W09 ... it should normally work without any issues !
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] friedsonjm:
What can I do to get you information that might help?
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
Well, let's wait a bit for other feedbacks !

This it's the first time when kernel & ROM use the new Oreo sdcardfs implementation , maybe you need to format data into TWRP ... also do you tried to boot with older boot for W09 ?

Also could be a issues from my part when I packed the new boot for W09, but it is unlikely to be from here.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] friedsonjm:
I did format data. I have the previous boot image, I'll try with the new ROM and previous boot image and report back.

---------- Post added at 01:41 PM ---------- Previous post was at 01:33 PM ----------

I used the new ROM and the previous boot image, and it booted. I wiped everything except SD Card and formatted data before installing.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] martymcbro:
Same behaviour for me with W09.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
Ok, I need the content of sys/fs/pstore from TWRP ! After device stuck on boot, you need directly to force boot on TWRP to be able to take the correct content of "pstore" !

Just compress the new "pstore" folder and upload it somewhere, thanks !
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] friedsonjm:
OK, done and uploaded to https://drive.google.com/file/d/13gMYg9d0YpMbTB_aqKnRj8cOVJVz06po/view?usp=sharing
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
Right now I re-uploaded another boot image for W09 in OP ... I hope it works this time !
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] friedsonjm:
YES! Successfully dirty flashed ROM and Boot image over previous version, and booted OK
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] Vesko01:
I installed the latest image, works without any problems. I can confirm that the charging screen now works. I would like to report an issue though: on the last update I noticed that the auto brightness on the tablet does not function. Its not a fatal flaw, but recently I rediscovered this feature and It has started to grow on me, so I wanted to start using it on the tablet to. I would really appreciate it if you could look into it when and if you have the time. And one more time thank you so much for your work!

Edit: I just found out that I cannot connect the tablet to my PC anymore. It does not recognize it and I can't find out why.. If you have an idea [MENTION=2335078]surdu_petru[/MENTION] or anyone else with the same issue, please give suggestions!
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] Half Alive:
Hmm can confirm the pc issue.

It says *USB device not recognized* on win 10. Switching between modes give the same thing (charging, transfering files...).
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] friedsonjm:
I usually download the new ROM/boot files into my PC, then put tablet into TWRP recovery - in that mode I can see the tablet and transfer files.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
Thanks for your feedback !

Unfortunately I use Ubuntu and there is no issue on connecting my device via USB ... yes, you are right, I tried now on Win 10 and it dosen't seems to be recognized .... I'll look into this issue soon !

About auto brightness, there is no issue on my tablet BTV-DL09 and I guess it should working on your device too, if not try to make a clean install, thanks !

Yes, but this is not a reason to justify the failure of the USB connection with Windows 10 !
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] chris_6597:
I updated to new ROM and confirmed that the same issue(PC could not recognize m3). Also, I could not download files in Chrome, firefox and vanced manager.

I wonder if it would be the file path problem.

I have another app that could not read the downloaded file on the folder of internal storage after the update. However, after re-specify the folder path on the app GUI, files could be read and the folder path become "content://com.android.externalstorage.documents/tree/primary%3a#internal storage folder name#%2f#the folder inside internal storage folder name#/document/primary/%3a#internal storage folder name#%2f#the folder inside internal storage folder name#"

Although the path state the path is external storage, the downloaded file and folder are in internal storage.

Now, I go back to my backup.

Also, I have another issue. 720p60fps video with 2x speed on YouTube app(both stock and vanced ) could not be played smoothly. For example, [youtube]Cyxixzi2dgQ[/youtube]

Even I factory reset the device, the program still exist.

However, when I am using youtube web (both desktop and mobile version), this problem is not come up.

How to disable 60fps on the YouTube app as an alternative?
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] Half Alive:
The 60fps YT app is is a known problem and it happens with normal speeds also.

Can confirm the permissions issue with a clean install.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
Ok, I reverted some commits and disabled also some configurations and I managed to fix USB recognized on Windows 10.

Adaptive brightness & download attachments should be also fixed on certain devices where they do not currently work.

Sdcardfs kernel drivers was disabled as doesn't seems to fix adoptable storage, but instead it seems that create more issues.

I'll prepare for tomorrow night a new update with all these fixes :)
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] zzyglrox:
Hello and thank you for all your work on this! With your help I was able to successfully install the new ROM today on my BTV-DL09 - but without it detecting my SIM card.

I'm showing:

productid=0x3c22040c
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
New release 17/11/2020 !

Hi !

As I promised yesterday, I come back today with a new update !

The changelog it's the same as the update from two days ago and can be checked here.

Additionally fixed :

- USB recognized on WIN 10

- SIM enabled for all devices with productid=0x3c22040c

Please, check OP for download link !

I hope that this time everything will work as it should :)
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] Half Alive:
Working fine and smooth now.. USB is recognized.

I noticed that you've fixed the wifi hotspot.

Also the Cast functionality on the *not working* list. Is it just about casting the screen? as it's working fine or there are still some apps that have problems with it?
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] zzyglrox:
Thank you for the quick response! LTE is working now, as is everything else so far.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
It say "No internet connection" when I tried to connect one device via hotspot with my tablet !

Ok, I didn't checked right now if Cast it's working .... I'll remove from state not working if no one complains about it !

Thanks !

Ok, good !
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] Half Alive:
5ghz gives an error and it doesn't enable the wifi hotspot.

2.4ghz works and connects to the internet on my phone.

Edit: Also connects fine on my Windows laptop.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] friedsonjm:
Up and operational after dirty flash, working well so far with known limitations, thanks!
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
Ok, so I can connect almost all my devices ( Laptop with Win 10, Desktop with Ubuntu, MediaPad M3 Lite 10 with Android 10 & Oppo Reno2 with Android Pie ) via Hotspot but I have the same issues on all devices : No internet connection - so it's just a usless conection !

Also I tried to Cast my device on a TV Samsung Q7 but there is also a issue, as soon as I try to connect to my TV listed in the Cast menu, from the unknown reasons the connection is restarted and the Cast menu becomes empty ... but after a few seconds my Samsung Q7 TV is listed again on the Cast menu - so there is no way to establish a connection via Cast - at least on my BTV-DL09 !
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] Half Alive:
That's what I'm trying to clear.. For me there IS an internet connection.. Totally not a useless connection. I hope more people can try and report back.

For casting I think now I understand the problem. It doesn't work on wireless display..But it'd cast fine to my Google chromecast as it's not a wireless display. And yes I'm not talking about casting videos. Mirroring the screen and audio.

Sorry to report that it was working without giving details.

Same BTV-DL09.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] zzyglrox:
I can confirm that hotspot is working for me - there is an internet connection and it works. 5 GHz gives an error and doesn't enable the connection though.

I am having a problem with access point names though. When I connect to my carrier I get a list of 6 APNs. There is a particular APN you must use for tablets, all others will result in roaming charges. Whenever I reboot the tablet or disable/enable the mobile network connection it is automatically connecting to the wrong APN by default and I must manually change to the correct APN each time.

I am not sure whether this is a problem with the ROM or with my carrier, but when the tablet was running EMUI it would always reconnect to the APN I had selected when mobile network was restarted.

Thanks again for all your work on this.

EDIT: I checked with my carrier and they were able to confirm that, as I feared, the problem isn't on their end and that it's most likely the device that is switching the APN on me :(
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] friedsonjm:
Netflix / Magisk

I've installed Magisk and Magisk Manager, hid all Google apps, installed Busybox and MagiskHide Props Config via Magisk, ran props in a terminal and selected a Huawei device that used Android 8/9, selected 8.1 ver. Rebooted between steps. Checked Safetynet which now passed. Play store now shows Netflix, which I installed and ran successfully. I don't know if all that will survive even a 'dirty' flash to the net ROM version, will find out! There is also a Magisk Netflix Enabler module, I have not tried that one.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] martymcbro:
On the next dirty flash you will have to flash Magisk again. The fingerprint faking / props modifications will still be active and don't have to be repeated. At least this is what I have observed.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] nick2506:
I'm able to install the LOS 15.1 Rom for BTV DL09. But, there are some issues in it:

-bluetooth can't work properly with headsets

-youtube stutter when playing in higher definition(my internet connection is stable so it won't be internet problem)

-overheating issue with no heavy usage (youtube for 10 minutes and found my tab is on light fever)

hopes developer can fix this issues in upcoming updates ^^~
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
I'm sorry, but all your issues will not be fixed !

I have two pairs of bluetooth headphones and both work fine, except when the device it's connected in the same time to wifi !

It's a known issue with youtube, so you need to switch to a lower definition.

After 10 minute on youtube it's normal that the device to become a little hot.

As you can see there are not many possibilities, just stock EMUI and LOS 15.1 ... anyway, you are free to use whatever you want !
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] zzyglrox:
So it looks like I was able to fix my APN problem. I was able to edit /system/etc/apns-conf.xml and noticed a line saying APN type=default and moved that from the wrong APN to the right one. Now the tablet is sticking to the APN I need to use.

Since as far as I can tell these APN settings are coming from Google, this line was presumably in there when the tablet was running EMUI, and it wasn't switching on its own. So whether this is something to do with the ROM or not, I'm not sure, but it's looking like I've solved it.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
On my device, APN type = default,mms,dun,xcap - and I still can't use wifi hotspot on other devices !

And I have only one APN, so I can't choose from more APNs
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] zzyglrox:
To clarify, the APN problem of mine was not related to hotspotting, but to mobile internet in general. The data was working just fine on the wrong APN, and presumably the hotspot was too, it was just being billed at $1/MB by my carrier rather than at my normal data rate.

Whether any APN settings are causing your hotspot not to work I don't know.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] Userusing:
Hello,

First of all, I want to thank you for your amazing work. My tablet is btvdl-09 and it has become super fast since the I switched to LOS.

In the latest update, random shut downs (under heavy tasks) are gone, navigation keys problem when typing in horizontal mode is fixed. Wifi speed issue when tablet connects to headset through Bluetooth, is gone... Except my bluetooth keyboard (logitech k380). It connects but the tablet suddenly shuts down and boots into eRecovery. I sent links of console-ramoops-0 and dmesg-ramoops-0 files (as you mentioned logcat is useless after reboot in LOS 16 thread) as I don't know how to attach files to posts in threads. Also, I flashed your previous kernel update (boot_lte_4.3.0.img) into the current update of the rom and surprisingly I had no shutdowns but i got the wifi + bluetooth problem back.

Again, thanks for your hard work. I really appreciate it.

users of this os, does the right click of a mouse behave like back button?

Or like right click
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] Userusing:
doesn't behave like back button in my btvdl09, behaves just like right click. (Tested in bromite browser and functioned like long pressing for hyperlinks)

anyone have play store issues? it seems storage access broken...

i insert sd card and format internal storage, but still can't install bigger apps...
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] friedsonjm:
Only 'Portable Storage' works. However, even as portable storage, you set apps to use it - such as Google Maps and Kiindle reader- and save a lot of internal storage space.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] Garry050:
SD card doesn't help anything...

I can't install 40MB over apps. (Firefox,Chrome,Amazon,Kindle etc etc)
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] tek3195:
Can't partition sdcard either. Trying to use

sm list-disks adoptable
disk:179_192
sm set-force-adoptable true
sm partition disk:179_192 mixed 25

Ended in reboot to fastboot mode with this onscreen message:

TView attachment 5153995

The only way I found to fix it was full wipe with data format. Without data format it couldn't mount or unmount /data and dirty flash of los.zip btv-w09 boot.img and pico gapps reported success but booted to bootloader again after a brief glimps of los boot animation.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] friedsonjm:
I have found that the only successful way I 'recovered' an SD card that I had tried to format for adoptable storage was to re-partition in on a PC, using Partition Magic or similar software, then put back in the tablet and format as portable, not adoptable storage.

Also, make sure you are using the correct TWRP as posted in the OP.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] tek3195:
Yeah, that's what we were doing in the beginning with this rom. I always use gparted to fix sdcard. This time that did not work and before I don't recall it rebooting to bootloader or seeing that message. I don't know that anything was wrong with the sdcard, I actually just swapped it out with a fresh spare. The problem seemed to be strictly internal as after re-flashing everything and booting successfully, I replaced sdcard with first one and it formatted the first partition external and didn't touch the third. Now that I think about it I don't remember if there was a second for android_meta or not. Keep in mind I was partitioning the card and not just formating it. I mainly posted this experience to share the screenshot in case that info may be useful at some point.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
Hi !

New Update of LOS 15.1 for Beethoven devices ! Please check OP for downloads !

Changelog:

update security patch to : December 5, 2020

Thank you for your attention !
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] tek3195:
@surdu_petru can you take a look at this to help me determine why I am getting bootloop. It is a soft reboot, hot boot, or UI reboot or whatever it is being called now. It boots the UI for about 3 seconds and goes back to boot animation screen. https://www.mediafire.com/file/kxri7kkhjhwa2a3/logcat.txt/file
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
You have some AndroidRuntime FATAL EXCEPTION and this one "E AndroidRuntime: Caused by: android.database.sqlite.SQLiteCantOpenDatabaseException: unknown error (code 14): Could not open database" seems that /data it's not accesible on your device .

My advice is to clean /data maybe format /data into TWRP and try to make a clean install lafter for LOS !

I can't help you with more because I don't know exactly under what conditions you have these issues.

Also a logcat should be taken immediately ( even before with a few seconds ) when the boot animation start ... and let like that until the device boot or restart !
