Many thanks Surdu.

Updated from 21.1.2021 build on my w09.

Steps: installed build, wiped cache /dalvik, installed Boot.IMG 21.1.2021

Rebooted, works fine.

Keep you posted, next days .
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] sergio_sant:
Updated my W09

It seems to be working well and feels snappier than before!
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] friedsonjm:
Well for some reason, my tablet is not not showing up on the file menu of my pc, and I'm in recovery, and can't boot to system. Tried to move the new boot image using adb sideload, but TWRP rejects that as it is looking for a zip file. Any suggestions for moving the boot image to my tablet, other than pulling out the SD Card and loading that separately?

EDIT Yes I've disconnected and reconnect cable..

EDIT Pulled SD Card, copied boot file to SD Card, now TWRP/Tablet won't mount the card..

EDIT: Pushed zip and image to /sdcard (not external sd), went to install zip then,

Still getting 'Can not create external_sd folder error' when installing zip, then 'Unable to mount

storage'

Now trying to boot to system....

Getting the Lineage 'moving circle' automation... but taking a long time. I'll wait.

EDIT: Reinstalled, again.. no error messages. Rebooting to system, again....

EDIT: no-go.. will restore from backup, if that works, reflash boot and zip...

EDIT: Restore booted OK
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] earlg100:
YouTube works as promised. Very fast.

Total behavior is very fast compared to 21.1.2021.

5ghz Wifi is still dropping connection while tab is on standby.

2.4ghz is working properly.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] mogulman01:
Dirty flashed ROM and boot file for w09. Seems to be working fine for me. Thanks for the update!
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
I have checked right now and there seems to be a strange behavior to GPU test for Antutu ! It's working well only after device was restarted or if you run Fill RAM memory. Ok, I guess I know what's wrong here and the issue will be fixed on the next update, update wich will come with the new security patch for February !
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] mogulman01:
I ran Geekbench 5.2.5, I'm getting 144 Single-core and 490 multi-core? any ideas? do I need to try a fresh wipe/flash?

Rebooted...now 353, 1299
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
It's working well if you reboot the device ... unfortunately I realized now that I made a mistake on the kernel ... it's not a very big issue but will be fixed on the next update. Thanks !

You are right, and thanks for your info ... it has nothing to do with "apps running in background" instead it's something wrong on my kernel, and I already know where. It only remains a matter of time until will be fixed.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] friedsonjm:
Well, no I've got real trouble... restore worked OK, but not installing new ROM. Long story short, I've tried a complete wipe, then went to format data, getting error 255

See attached image... anyone got ideas?

EDIT: OK, just booted new installation... will have to reinstall 'everything.'

EDIT: Could not install GAAPS; not enough room, as data partition not available.

EDIT: I've 'repaired' data partition, formatted data partition, and still have the same problem.

EDIT: I think I've been chasing the wrong problem...

EDIT: So, got pico GAAPS installed, now, when Lineage is booting, getting 'Encryption unsuccessful' error. Very difficult to get back to recover, goes into fastboot instead. Fastboot reboot recovery is not working, just tries to boot into system. I've re-flashed TWRP. Not sure of what to try next. WIth keys, get briefly into TWRP, then it immediately tries to boot system again.

SURDU - do you have any thoughts?
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
Do you tried to flash the new ROM without external storage in your device ? I guess you should start from scratch all operations, but this time just pull out your micro sd , as your first issue was related to external_sd, guess something it's wrong with it.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] DVSGUY:
Maps.me loads now, everything seems a bit faster. Only thing left on my wishlist would be to be able to connect to stealth SSID wifi networks.

Thanks, it's like I a bought a new tablet! (Which is great because I don't see anything on the market that seems to be a good update for a reasonable price.)
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] earlg100:
Did you check the MD5 Hash of your downloads? Maybe something was corrupted? If nothing works, maybe you have to go back to stock (like mentioned in the "unbrick" thread)? And start from the very beginning.

Btw. I had no mircoSD plugged in while flashing... Maybe this was the difference.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
I flashed with microSD into my tablet and no issues here.

But maybe it's worth a try from stick.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] friedsonjm:
Well, the problem occurred after trying to boot with the new ROM and old Boot image, but I'll try without SD card, thanks.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] friedsonjm:
Removing SD card did not work; trying to reformat partitions with fastboot erase, but getting 'command not allowed.' Is there an alternative?

EDIT: Guess I'll download stock ROM and start from scratch...
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
It should working also with older boot.img as I already checked yesterday.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
Does your frp is still unlocked on fastboot ?

Edit: if frp is locked you'll not be able to write partitions with fastboot command.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] friedsonjm:
I am able to push TWRP with fastboot, then use fastboot reboot recovery, but when TWRP boots, after a few seconds, it reboots. Does that mean frp is unlocked? Or if I need to unlock it again, how?
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] Me,You,and Daigorou:
Thank you surdu_petru.

BTV-L0J, Dirty flash the latest ROM, No problem, It works fine.

Youtube(NewPipe) plays smoothly 1080p60fps videos. It seems to me that there is no new issue caused by the last ROM.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] accerian:
Happy to help since I don't how to build or debug roms :)

Do you have any good tutorials you can recommend ? :)

I have installed rom , ATM it work good including youtube , only issue I have right now is that netflix is not letting me download anything , I'm getting error : "OF.NA.2"

On 15.1 I was able to download from Netflix without an issue.

Antutu after reboot work fine , but write performance is very low

Sequential 133MB/s

Random Write 3.9MB/s

If I remember correctly there was option to change queue size in kernel to have better performance , but I might be wrong
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
You can unlock frp only from developer settings ,( oem unlock) ... but when you boot on bootloader mode it's state there the status for bootloader & frp .

Edit:

You can try to wipe data via fastboot :

fastboot erase userdata

or

fastboot -w

Maybe after that you can use TWRP properly.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] friedsonjm:
Fastboot -w 'worked,' but booting into recovery still have the same problem.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
No, unfortunately there's no tutorial for such things, you can learn yourself consulting many github for others devices and try to understand what they did and why, also you can check gerrit commits where they detailed almost all commands added on a device tree, but of course all theses takes a lot of time.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
Did you tried to flash TWRP once again ? After wiped data with "-w" ?

Edit: if nothing working you can try to boot on stock via dload method, it's working 100% if you put the right UPDATE. APP on your microSD card /dload folder and use all the three buttons to start flashing from dload folder.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] friedsonjm:
Yes, that's exactly what I did.

Now I've download factory firmware, placed update.app in sdcard dload directory, it tried to install, but failed.

EDIT: this is just getting worse. Removing SD card, and trying to boot into fastboot, tablet is just looking for 'update' and fails. <sigh>
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
It should working but I guess you have 2 issues :

- make sure that your microSD it's working properly on other device

- make sure that you have the right UPDATE.APP
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] friedsonjm:
I am going to re-download from a different site...
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] friedsonjm:
For some totally unknown reason, TWRP decided to be stable, I wiped everything, installed ROM, and booted! Now to solve the Play Protect error.. again. :)
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
I'm glad to see you solved the problem :love:
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] Hauxx:
Hi I installed Lineage 01/28/2020. But it caused a bit of trouble installing Lineage. I also had to wipe the DATA partion. Without it, it got stuck in the loading screen of Lineage. Maybe to many Dirty Flashes. Otherwise everything is going well so far.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] friedsonjm:
Do you have the wifi only model? If you do, did you remember to flash the boot image?
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] Hauxx:
Yes i tryed 3 or 4 times with the new boot image 28.01. But it works now after i wiped DATA too.

Video resoultion:

Old Version	New Version
Chrome	4k	720p
Firefox	720p	720p
Youtube App	4k	1080p
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] friedsonjm:
OK, using Google Maps, with save location as SD Card [formatted as portable storage] I am getting the connection error. When I set it to download to device, it does download.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
Your test it's not relevant at all ... why you need 4k without hardware video decoder ? without it you are not able to play a video from Gallery 1080p properly !

With this new version there is a huge improvement on all video format, and also it's working to play 1080p 60fps which it's working only on the last update of LOS 15.1 !

EDIT:

Please download bbb_sunflower_1080p_60fps_normal.mp4, put it on your device and try to play from gallery on older version, and you'll see the difference !
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] friedsonjm:
Kindle cannot download books, to device or to sd card.

Also, even with SD Card set as portable storage, I normally am able to go to Settings->apps and move certain apps to SD Card. With this version of the ROM, no apps have that option.

Both Kindle and app movement to SD Card worked in the last version. :)
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] 30adi:
Can someone tell me how is lineage os 17.1 compaired to latest lineage os 15.1 build?

May be used as a daily driver?

Than you!
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] friedsonjm:
I would say, close but not yet. Those of us who are participating in using it right now, do so to assist the developer. For example, recent fixes allow me to share from a news app to Facebook, but I can't download Kindle books, etc. I don't do much video/you tube, so can't advise there.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] 30adi:
The for reporting back. I will wait for the next build then, as this tablet is used also by my son :D
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] friedsonjm:
This logcat shows the attempt to download a book on Kindle app.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] god123456:
thank you for the new build,youtube work like a charm!(y)

anyone face bluetooth headset keep reconnect and force close?
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] god123456:
just tested 4 bluetooth headsets,i found that those 2 old headsets working normal,other 2 newer bluetooth (4.0 5.0 aptx hd......) keep restart and force close,i am thinking maybe bluetooth codec problem?kirin 950 not support aptx??
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] Hauxx:
I'm just saying that Chrome "Google Play app" has lost the option to watch 1080p, I don't need 4k. I also found out that the internal browser app (Chrome) does 4k, but it has scaling problems with it even in 1080p 720p it doesn't use the whole screen on Youtube "mobile view". The "desktop view" works better
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
Yes ... Kindle, MAPS.ME, Maps can download only on internal storage .... if you want to download on external storage you must format your microSD as internal storage, after that move for example Kindle from internal storage to external storage and all Kindle downloads will be saved on external storage ( microSD ).

I already checked on my M3 Lite device ( qualcomm snapdragon version ) with also LOS 17.1 and I can't save to external storage content from Kindle & Maps ... it's working only for MAPS.ME !

EDIT:

At the moment I have no solution to this problem, but maybe you can find someone who had this problem and solved it !
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] friedsonjm:
I am not able to get Kindle to download at all - even to internal storage. I've uninstalled and reinstalled, same problem. My SD is formatted as portable storage, I'm not trying to use it for Kindle. ??
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
EDIT:

I'll try to check LOS 15.1 the last update to see if we have the same behaviour !
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] friedsonjm:
Kindle was working with the previous version of this ROM, 17.1 using internal storage. :)
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
For me it's working also with this version, but download only on internal storage !
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] friedsonjm:
See below - I have no idea why it won't download to internal. Maybe I'll try installing the ROM and boot image again and see if that helps.

[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
I don't know ... but maybe I already modified something on my build and that's why is working on my device ... anyway someone could confirm whether or not it goes download on internal storage for kindle in this new version !

I can check again in a few minutes after I'll revert back to LOS 17.1 !

BTW, LOS 15.1 the last update it works almost perfectly - no issue there to download on external storage ( not format as internal storage ) for Kindle, Maps or MAPS.ME !

EDIT :

Who wants a good custom rom, even if it's only 8.1 can turn to LOS 15.1 - it's much faster and almost all seems to working without issues.

Unfortunately in LOS 17.1 we don't have a 100% functional hwcomposer and that's a pretty big impediment ...

EDIT II:

@friedsonjm

It's working also on the last update of LOS 17.1 :

I just installed LOS 17.1 the last update on clean ( wipe System, Vendor, data, cache & dalvik from TWRP ) - no backup restored !
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] friedsonjm:
OK< I got it working! Uninstalled both Kindle and Amazon shopping, reinstalled ROM and Boot, installed Kindle, MANUALLY set storage permission to ON

Now it works! :)
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
Ok, Good !

I made some tests and I found out why all applications can't save content on external storage !

Now it remains to be seen if I can find a viable solution to this problem and how long it will take me to solve it !

BTW, the both issues ( this one with external storage ) and also the low score on Geekbench 5 are kernel related !

I hope to fix them both until the next update scheduled for February 15 to 20 (depending on the availability of the new security patch), maybe even sooner !

As soon as I'll be able to fix these issues, I'll restart working on camera !

[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
@friedsonjm

The sdcardfs kernel driver is at the root of problems with downloading content on external storage !

On LOS 15.1 I managed to disable on build.prop sdcardfs by using ( ro.sys.sdcardfs=false ), unfortunately this workaround does not work in LOS 17.1.

We have the same behavior also on LOS 15.1 if ( ro.sys.sdcardfs=true ). ( Kindle, Maps or MAPS.ME can't save content to external storage )

I already checked my sdcardfs kernel drivers and seems to be ok, in fact is the same driver used on all Android devices which use 4.4 kernel ! A possible incompatibility can only come because I upgrade the kernel from 4.1 to 4.4 - this is just a guess , I'm not sure because the sdcardfs kernel driver can be compiled without any issues...

No one have this issue, so it's hard to find a solution in this case.

I already tried to use Huawei sdcardfs kernel driver from Android O ( because this kernel it's based 4.4 like our kernel ) and with this older driver we can't use at all internal or external storage ! Also tried to use Huawei sdcardfs kernel driver from Android 10 ( but this time kernel was updated by Huawei to 4.19 and there are many incompatibilities ) - anyway I managed to fix all sdcardfs kernel compilation issues, but in this case our device stuck on boot without bootanimation, after a few seconds my device reboot to erecovery !

Although I don't think there is a solution, I will still try to find and compare other sdcardfs kernel drivers compatible with 4.4 kernel, so far I have checked the drivers on oneplus and xiaomi devices that use the 4.4 kernel - and it match perfectly with our sdcardfs kernel driver !
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] friedsonjm:
well, we thank you for all the hard work you have done to date, and have confidence you will still solve problems going forward!
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] Grander77:
First of all, many thanks for the further development of the software for the BTV!

I've already used LOS15 successfully, now I'm trying LOS17.

Unfortunately, I also have the WiFi error (exactly as in post # 4), now I'm excitedly waiting for an update (y)
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
Hi !

There is a new Update of LOS 17.1 ( second test ) on OP !

The name of the ROM remained the same, only the download link was updated.

Changelog:

new security patch : December 5, 2020

fixed warning message : "There's an internal problem with your device. Contact your manufacturer for details."

audio partially fixed ( in the same way like on Pie )

bluetooth

4G/data fixed ( for Non WiFi devices )

Please check OP for download links and also for a complete list of what currently works on this device !
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] earlg100:
I am really looking forward to a "half stable" release. Currently I can not join your "test force" , cause I need the tablet in a working state. I'm still on your 15.1 release and appriciate your hard work! Keep going Surdu!!
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
Ok, thank you very much for your appreciation !

I hope to solve the issues related to GPS and WiFi soon ... to making the ROM "half stable", but it seems that in this version of Android, the issues are a bit harder to solve than on Android Pie !
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] Grander77:
Is the new file (second test) faulty? Md5 is correct, but several programs say the file is defective (error in file, unexpected end of archive .. etc)? Multiple downloads from different servers - same result.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
Thanks for the information, I downloaded right now and indeed there seems to be a problem ! For some unknown reasons the ROM wasn't fully uploaded.

I'll try right now to re-upload the whole ROM from yesterday !

EDIT:

OK, Fixed !
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] friedsonjm:
Internet is insanely slow today... looks like it will take 8 hours for me to download the ROM!
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] friedsonjm:
OK.. fixed my modem problem and downloaded and installed ROM, GAAPS, and boot image.

No warning message, good. Still can't connect to wifi (networks do not show). Booted to home screen OK. Recognized SD card (portable storage) OK. Went to settings to try to turn wifi on, it won't turn on.

It's an improvement, but I think that's all I can do for now, will restore 15.2 backup.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] toystory2000:
Thanks for the effort to make m3 live again

May I know the link of lineage-17.1.1-btv.zip, thanks
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] friedsonjm:
It's in the OP (Original Post).
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] toystory2000:
Thanks for the reply, do you mean the first page of this topic ?
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] Half Alive:
Glad to have Audio and LTE .. Got to finish setting up the tablet, and some apps that didn't work with reverse tethering worked after it launched first with the LTE connection.

Magisk also works in this build.

One question. My Bluetooth headphones keeps reconnecting to the tablet. Is it related to our audio problem? Or should provide a logcat.

Edit: Netflix doesn't work for some reason. Spotify freezes when opening a video. Like a video podcast. YT app limits 60fps videos to 480p. Rarely it wouldn't but when it doesn't do that the video works smoothly without stutters in 1080p60. Normal videos work fine at 1440p.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
Please, does you have the same issue with your Bluetooth headphones on LineageOS 16.0 Android Pie ?

Video it's not stated on the Working List from OP ! I'll try to fix also this issue soon !
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] Half Alive:
Aha, because videos on YT work fine I thought we don't have an issue in this area.

For bluetooth I didn't try on pie but will test it asap.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
GPS Fixed right now on Android 10 LOS 17.1 !

EDIT:

WiFi fixed right now too !
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] friedsonjm:
Terrific! Will try as soon as new version posted. :)
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
Ok, I'll try to fix also video issue ... as we can see on this ROM we can't play any video from Gallery !
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] Grander77:
The second beta is installed. I can't test 4G, only have the W09. But the rest is already going great. Unfortunately, I can't test a lot without working WiFi :giggle:
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
