What's Not Working :

Camera

USB tethering

Encryption

SELinux disabled !

there could be also others minor issues !
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] Ryan650:
Guys, how's the camera repair going? I still use los15. The camera is very important to me. Or is it possible to fix it? come on. LOL。
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
Yes, use LOS 15.1 if you need camera , thanks !

Hello, will you update this device to Android 12L? It seems that many tablet features are added in this version.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] terry_mccann:
It is really amazing what an arrogant ....... you are. You may undeniably have done a great job on these LOS-roms but you are treating people like sh...t. Not good.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
for your information, you should know that anyone who asks a question here or has a concern has first of all the obligation to inform themselves or at least read the official post in its entirety... there is no reason to answer to a question where the answer is already clearly written in the OP !
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] terry_mccann:
Yeah well, making it quite easy for yourself.

But each to his own.

Excuse me，How will I upgrade from my EMUI 5.0 Android 7 to Los17.1

Is this the process?：

1:EMUI5 > los17.1 Or 2：EMUI5 > los16 >los17.1

I want an upgrade plan.

Thank you.😃

Hi, @surdu_petru

can you share your android_hardware_huawei tree?
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] Quinlu:
Hello,

Its been a long time since I last flashed a phone/tablet. I've read the OP and I have a doubt:

Under downloads there is a file "only for wifi devices". My tablet is a BTV-W09 wifi only so I understand that I need that file, but when do I flash it? Do i flash it instead of LineageOS-17.1-BTV_2022-05-14.zip??

Im quite confused, thank you for your help!
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
Yes, install the .zip archive and after that you should install the fix for BTV-W09 wifi .
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
No, but if you're interested and you have solid knowledge into development I can help you to make your own device/vendor tree!
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] Quinlu:
Thank you! Incredible work
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] terry_mccann:
I had a few runins over the months with the creator's behaviour which I still find weird but I really have to say, the ROM works great, gave my M3 a second life. Quicker than stock, less batterie drain and all in all running very good.

Only two flaws:

- camera not working, which is common knowledge and not important fpr my use

- as with stock, no Netflix- and Disney+-HD streaming possible because it is still Widevine Level 3. Is this a hardware thing or can this be corrected by Software I ask myself?
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] terry_mccann:
Oh, and Netflix doesnt work from Playstore. It says the app is not suitable for the device.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] terry_mccann:
Anybody know about Bluetooth? It crashes every time I try to connect headphones.....

prolly a dumb question but how can you tell if you have a 2 or 5gb System Partition?
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] hk56184172:
use MT manager,You can see it
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] hk56184172:
Will u fix the camera?I really need it.Thank u so much.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
If you need camera working you should switch to LOS 15.1 as it's working there !

Yes, our device it's Widevine Level 3 - so we can't do anything here .

Thank you for the understanding !
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
Sorry, I can't fix it on LOS 17.1, so if you really need camera working you can switch to LOS 15.1 , thanks !
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
Initially the system partition is 2GB, after applying all the steps in this post you will get a system partition of 5GB, as you can see it is not difficult at all to know which system partition you have in your device!

Android version is too low in LOS15.1 that i cant run some apps.But thank u for this build.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] diantama:
I also waiting the answer of this question.

Im on Android 7 EMUI 5.0.4 with twrp_BTV-W09_5_greatslon and really interest to upgrade this old device

I was trying using TWRP 3.3.1.1 but it seems little problem that it cannot read internal storage (show 0MB)

Need advice, thank you
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
All it's working here without any issues if you can read and understand the installation instructions from TWRP and also for LOS ! Your issue will be fixed after data format into TWRP, that's why there are installation instructions, to be read and followed step by step
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] diantama:
Thanks

Maybe i skip detail instruction:

* flash TWRP 3.3.1.0

* format data

* reboot into twrp

* copy LOS 17.1

* install

* reboot system

And I'm getting bootloop

What i missed

Now im trying to rollback and unlucky i was failed

Using IDT and hold on chinese ROM with EMUI 2 :cry:

No, even swiping from the top of the screen does not work.

EDIT: Play Store version is 23.2.11-21 [0] [PR] 347100967

[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
Ok, good !

I'll wait a bit until orangpelupa & Half Alive will test this update, maybe they may find an idea of how we can fix the issues for applications that refuse to start like : maps.me, instagram, facebook and so on !
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] friedsonjm:
We know there is an issue with apps being able to download, such as Amazon Kindle. Could it be that these other apps, which are both RAM and disk heavy users, are trying to download when they start up, and when they can't, they force close?
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
Yes, sure the issue could come from here as well ... but I'll prefer to fix from logcat, and at this time I found some issues about facebook and also instagram into logcat :

Unfortunately I did not find anything relevant related to these issues by searching on google !

EDIT:

I already tested facebook & instagram on LOS 16.0 and it's working ... so the issues seem to be only on Android 10 !

EDIT2:

I made this test and it seems that there is no RAM/GPU/CPU issues !

For me after installing newest update I wasn't able to unlock tablet , I had pattern turned on before installing udpate . After putting my pattern screen was going black and then back to the lock screen.

Tired to downgrade but after my pattern was not working at all :) Had to do clean reisntall :)

So I propose to turn off any pattern/pin before installing 26/12 update .

Also funny thing , I'm unable to get android_id for tablet reg via CMD/Power Shell

I have to go to shell then use nano to open file and manually search for android_id .

Is anyone else is having this issue?

[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
Good to know ...

BTW, I have already restart update the kernel with all the critical drivers ( as for moment it's still for Oreo or early Pie ) ... after that I will try to see why we can't install PlayStore as before, I see here some documentations ... I never tested with CTS before but I'll give it a try soon ... and in the meantime we hope to find a fix or at least a workaround with these larger applications.

EDIT :

I'm currently on kernel 4.4.143 and there was a lot of new patches for f2fs & binder !
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
I started the CST test at 19.05 ... and is still running at 22.22

Does anyone know how long it takes approximately, or do I wait a little and disconnect the device from the test ?

Programs that try to do downloads, other than Play Store, are for the most part not working with this version.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] sergio_sant:
Have you checked in App Information if there are permissions for the app that have been denied? Something similar happened to me (Vanced Manager couldn't download YouTube Vanced) and it was because access to storage had been denied without even asking. I changed it manually and it worked.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] friedsonjm:
Yes, the problem varies by app. For example Amazon Kindle will not save to SD card, only save to internal. Facebook will not even load, but Facebook light does work. The developer is hard at work at the next version, we just need to give him a chance to get it out.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] jotajota1984:
Sorry I miisplaced my comment in this thread instead of the LOS17.1 for m3 10 lite.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
Perform a clean wipe for the first install ! - you skipped this step

Mean that you need to wipe all ( into advanced wipe menu ) apart Internal storage & Micro SD card (if available ) !

EDIT :

if in the meantime you have installed another version of Chinese EMUI Android, you must ensure that your device is running Android 7, EMUI 5 as stipulated in the OP: ROM Firmware Required: Stock Android 7 (Nougat) - EMUI 5.x - before retrying to install LOS 17.1 - otherwise the device will enter the bootloop again !

EDIT II :

also you can get into bootlop after LOS 17.1 installed if your device it's wifi only ( BTV -W09 ) and you didn't installed the required boot.img
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] diantama:
Well noted

All requirement checked

Justs skip clean wipe 😢

But at least i learn how to revive my dead device using IDT, rolling back to the very basic ROM running EMUI 2 than upgrade again to EMUI 4 haha

Thank you for your replay

Hello! I tried to instal lineage os 17.1 on wifi mediapad m3 but after rebooting the device i get back always to huawei erecovery. After reading some post i have notest that i need to boot the wifi image. I have use install image in twrp recovery and choose boot image but after doing rhat again device reboot to erecovery. I did clean install. Do i miss something?
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
there are many things to consider before installing LOS, it would be best to spend a few days reading and informing yourself (some older posts had the same problem as yours and this way you will see how others solved it problem) ... for starters, as clearly written in the OP, your tablet must run Huawei EMUI Android 7, then I think you must have skipped one or more steps in the installation instructions

[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
Yes, TWRP 3.3.1-1 it's mandatory for installation of LOS 17.1, in fact you can use 3.3.1-0 only for install LOS 17.1 , but after that you must update TWRP in order to successfully installed GApps

also will the source be open, i think i could make the camera work ¯⁠\⁠_⁠(⁠ツ⁠)⁠_⁠/⁠¯
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] secret.animal:
Surdu_petru I understand your frustration. I see what is in the first post and being a well veteran of installing custom roms, others are still a wet behind the ears.

I to had a few problems, but straighten them out with diligence. I started with a btv-w09 WiFi only. Initially did as the first page said. Tried the newest lineage since gapps was going to be a problem, I installed the 5gb version and failed.

EDIT

Yes, I didn't follow directions very clearly. Do the edit on the post before trying to install 5 gb version. Install went without a problem. My own error. And don't forget your boot img if you have wifi only version.

No, I didn't give up. I researched a bit and tried an earlier version which was 2gb which was 2022-05-21. Yes I noticed I needed the patch. Quickly figured install img from twrp. And then LOS 17.1 , which I found in the image section at the bottom. Then remember doing wipes before and after other than system of course.

Error I get with 5gb is code 7 from twrp. But I do not ask for help I will find out and share with others off your post link..

For the other people I came from android 7 with emui 5. I flagged Twrp and then bored into recovery. Failed my first attempt rebooted to check something failed hitting into recovery. Stressed looked then found use both volume. Not just vol+, or up as bootloader says. And as I said before the 5-15-202 version. Working from there. Don't forget to wipe before and after.

I know camera doesn't work. Not a concern right now. I'll work with and figure it out also. A little tenacity and determination.

Thank you Surdu-Petru. For bringing life back to a old tablet I was still l very fond of.

Hi i am little noob so i wanted to ask something

My device btv l0j , sim model , which was converted to mediapad m3 , i was using lineage os on it. And i wanted to go back to the stock due to screen rotation issue. I tried to go back to stock using erecovery method. Put files in sd card and followed the whole method , the device went upto 80% and than showed an error . After that it showed only an option to reboot. When i pressed reboot the device went to a boot loop.

A bootloop of death.

I am unable to boot in recovery , cant even access fastboot mode.

I tried to get it fixed from the market but no one is able to do that.

And i am trying to get it back to life for last 4 months.

Can you please help me out. Is there any method to get it fixed , or i should throw it away.

Hi all,

absolutely perfect guide. I really appriciate! Even the 5GB system extension runs well.

Working great with my BTV-W09.

I am just fighting that playstore is uncertified after the install (used nano gapps), but I send my frame ID to Google. So let's see.

Again thank you very much :-)
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] tim_h:
Hi all,

just installed this successfully on my BTV-DL09 which I will then give my son. First had the original 2GB version, gapps-nano did not fit due to space concerns, gapps-pico worked fine. Then decided to modify partition table to get the 5GB system partition and install gapps-nano, only to then get the same problem as relaxxer - play services reported as being uncertified. With gapps-pico it now works (but could have saved me the work of changing the partition table and losing 3 GB worth of space on data partition). Anyway, maybe it is just a temporary issue with gapps-nano.

Cheers,

Tim

PS: What confused me tremendously is that it is impossible to plug in the cable to the computer once one is in TWRP. It will always reboot into some Huawei recovery then. Only way to get into TWRP with computer connected is to do an adb reboot recovery from within the system (which is obviously impossible if the system is not yet installed).

EDIT: Ok, now when I try to sign in to Play Store, I also get the "not certified for play protect" error, and it pops up with sound every few seconds. Sheesh, that will not be very useful. :oops: What can I do about that? It cannot be related to the modified partition scheme, can it? (If so, I guess I could just once more apply the procedure with the original values?)

EDIT2: Ok, I now went through the procedure of registering my android_id. @relaxxer did that work out for you? How long does that take? Is this android_id persistent over installing updates of the ROM or gapps?
