Thanks for all the great rom's!

By the way, do you plan to build crdroid?

I'm sorry because I can't help you with an answer right now ...

At the moment I'm very upset that the high speed internet (fiber) hasn't come yet ... I feel at least 10 years ago, because I only have ADSL and it works very hard :cry:

Hi @surdu_petru, I'm not very active on the forum, but i noticed that the last update for the ROM was almost 5 months ago. Is it possible that you have given up on this project? I really hope that's not the case...

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.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] acgin:
Hi, thx for the rom @surdu_petru

I'd like to address that even the stock ROM doesn't provide dm-verity/LUKS and SELinux feature in the first place.

Don't know if that is intentional or a flaw in the CPU/ROM design, but that isn't really the bakers' or the aftermarket ROM team's fault..

Also, is there anyway around to unlock bootloader without DC Unlocker? Because I don't have a Windows box and the client doesn't work with wine.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] acgin:
The power saving profile cannot be triggered.

That is a bug?
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] typeslowly:
Newbie here. First of all, many thanks to @surdu_petru for going to all the trouble to get this ROM working, and to the other posters on this forum for all your tips. After a few fits and starts, I've finally got LOS 17.1 running smoothly.

A couple of possibly dumb questions:

Given that this is an unofficial ROM, what is the process to get OTA updates (security patches, etc.)? Would I be able to apply those from within the LineageOS settings somehow, or do I need to wait for new ROM versions to be posted on this forum, and then flash them via TWRP? If the latter, is there a way to do so while retaining all my device settings/apps?

What are the implications of SELinux being disabled? Does this put my device at greater risk?

Thanks in advance for any feedback you can provide.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] friedsonjm:
As far as updates are concerned, you will have to wait for the developer. He has been fighting a multi-month battle to try to get his internet service restored to the point where he can continue to work on this rom, we do not know when that will happen.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
Hello !

Let the good news come ... finally, after long delays, I also managed to get back in step with reality ;)

Could you share where you ordered the battery replacement from?
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] Me,You,and Daigorou:
I ordered a battery replacement for my BTV-L0J to NTT Docomo(A

Japanese mobile phone carrier) for 42 euros. I think they accept this service only for people living in Japan.

Huawei still accepts battery replacement for the M3, but I think it is too expensive (about 92 euros). Moreover, the entire rear cover and battery will be replaced, so the BLU code will probably be changed as well.

So many people buy the battery from AliExpress for about 12 euros and replace it by themselves.

I personally don't want to buy a battery from AliExpress, but considering the price difference, I think I'll buy one from there.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:

Happy New Year !!!

I'm finally back here with a new update of LOS 17.1 based Android 10 for our device !

Changelog :

update security patch : December 5, 2021

I already tested this new update with dirty flash, and there was no issues ( at least for me )

With the new fiber connectivity, I managed to upload this new ROM in less than 1 minute, with the old ADSL connectivity the uploading time would have reached 6 hours ... so the difference is not small at all

Thank you all very much for patience !

We are right in front of the new Google Pixel 6 devices, which stopped for the time being in November, the next update being in a few days with the one in January because they managed to spoil more than improving the devices with the December update ! Yes, I switched from Oppo Reno 2 to Google Pixel 6 and I'm with the security patch on November yet !
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] friedsonjm:
Installed and running fine!
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
No, there is no bug ! It's working and you can enable "Extreme power saver" only if the device is not connected via USB !

Thanks, running fine for me too !

Do you have issue like @acgin , issue described with a line above ?
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] friedsonjm:
I don't know where to find/create a 'power saving profile.' I see profiles for users, Android Auto, and Silent. ?
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
Settings -> Battery -> Battery saver and performance -> Extreme power saver !

I didn't enabled Battery power profiles on this ROM, because I use the stock Huawei blobs for battery from Android Oreo !

It seems that if the device is rooted with Magisk, dirty flash fails.

Thanks for the update!

If you have some free time, please do a build of crdroid!
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
I'm sorry, but Lineage OS is and will be the only custom ROM released here !

CrDroid is based LineageOS, so it's not something very different apart that it has some more features.

The main reason is not that I don't have time or that I don't want to, but honestly I don't have enough space on my computer - considering that I use : ssd nvme m2, for increased compilation speed.

Hi Surdu, is that possible to build LOS 15.1? all​

LineageOS 17.1 that I installed has issue regarding​

"Device is not Play Protect certified", but LOS 15.1 works fine.​
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
Hi !

LOS 15.1 it's already released for this device !

There is already a FIX for "Device is not Play Protect certified" issue on LOS 17.1, you need only to check this thread !
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] Joelintw:
Hi Surdu,

I've tried new LOS 17.1 (2022/1/2), still have Device is not Play Protect certified issue, all LOS 15.1 version works fine. That's why I'm curious if you will build new LOS 15.1. :)

Besides, when I try to install open_gapps-arm64-10.0 (2021/12/17) to LOS 17.1, only PICO can be installed, tried to install NANO or MICRO, TWRP 3.3.1-1 always report error as following

"Insufficient storage space available in System partition, you may want to use a smaller Open GAPPS package or consider removing some apps using gapps-config."
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
Yes, as I already told you, there is a fix for your issue , you should check in this thread and applying it , do you understand now ?

Edit: yes, install only Pico Gapps, as there is not too much free space on our device with LOS 17.1

Hi Earlg100,

Actually I have tried the GSF register method many times and the way you did since Surdu release first LOS 17.1 version, until now it never work for all LOS 17.1 version... so I have to rollback to LOS 15.1
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
It's working for all people here, so it should working also for you, but you need to reboot device and wait at last 30 minutes after registration to be able to successfully sign into PlayStore
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] friedsonjm:
Actually, it once took about 3 hours for it to process for me!
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
OK, good to know ... it seems that this is why some people say that it does not work, in fact they does not wait long enough.

I have a good backup of LOS 17.1, so I can test over this backup the new update via dirty flash - and of course I don't need to register the device again , as it's already registered !

After that i installing the newest GAPPS for ARM64 Android10 Pico. Thats fine - but the Playstore is not able to certificate PlayProtect. I know how i can fix it, with the additional registration my Mediapad with the "Framework-Android-ID.

why cant i get this Playstore working ?
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:

So I've been using the rom since yesterday and I noticed some bugs:

- Sometimes when an app requires a permission, it does not ask you for it and denies it directly. Other times this worked like expected.

- Instagram won't launch.

- YouTube Vanced won't launch neither, it keeps showing the logo forever.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
Hi !

As I promised yesterday, today I come back with a new update of LOS 17.1 ... like always, please check OP for downloads link !

Changelog:

kernel update to Android Linux Kernel 4.4.130

fixed Fingerprint scanner

fixed microphone & audio jack

fixed microSD format issues

enabled High touch sensitivity

Critical updates needed in the near future for :

F2FS - our /data use f2fs and the kernel driver is not up to date !

Binder - binder kernel driver is not up to date !

Google GApps need registration !

After you have registered your device, make sure you perform a device restart /reboot operation ( about 10 ~ 20 minutes after registered your device ) - If you'll wait longer to reboot the device ( about 20~25 minutes ) then you'll be able to successfully login to Play Store just right after reboot !

Warning:

Starting with this update, your device will make a intermediate reboot right after boot animation finished !

There will be only one reboot when you install the ROM - no intermediate reboot later, when you want to reboot your device from whatever reason !

( this hack is needed for fix Fingerprint scanner )

Thank you very much for your attention !

i am not having any luck booting after installing on my BTV-W09. it will hang at the unlocked bootloader warning message saying the device is now booting, but it never does.

i am on 15.1 right now with TWRP 3.3.1-1 . i wiped data in twrp first. I have tried with and without gaaps. i did install the boot_w09_2020-12-26.img

any suggestions?
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
Please, use TWRP 3.3.1-0 for LOS 15.1 and make sure that you format data ( not wipe data ) !

EDIT:

If you switched to LOS 17.1, install TWRP 3.3.1-1, wipe all into TWRP ( System, Vendor, data, cache & dalvik cache ) - install the last LOS 17.1 & Gapps 10 arm64 nano and reboot !
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] friedsonjm:
My BTV-W09 has the new ROM installed, registered with Google, and apps installed. Will continue to test!

EDIT: Looks like apps still cannot download files to SD Card; I just tried Kindle, with setting to save to SD Card, with SD Card as Portable Storage, and that did not work. It did download when I changed setting to internal storage.

EDIT: Facebook keeps force closing when opened. I've uninstalled and reinstalled, same issue.

EDIT: My news and weather apps all work OK. Gmail works OK. XDA App works OK
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
I have the same issue on Facebook ... I'll look for a solution soon.

I guess that I need to update f2fs & binder kernel drivers because some apps depend on them !

BTW, it's the first time which I can play a video from my device to Plex !
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] sergio_sant:
Just updated. Everything worked fine until I set up a PIN and a fingerprint. I rebooted and got a bootloop. I'm reflashing now.

UPDATE: ok, so reflashing ended up with a bootloop forever too. So I flashed it back to previous release (from 20/12/20). It booted well. Though there was no PIN or pattern to lock the tablet, it asked for a PIN when trying to change lock settings. I tried the one I picked before reflashing but it did not work. So with a root explorer I deleted "locksettings.db" in /data/system. It worked, lock settings have been resetted.

It seems that the new release has a bug with PIN and fingerprint combined.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
On my device it's working well PIN + FPS ... I was previously to Pattern + FPS and I switched right now to test on PIN + FPS, I already rebooted the device and all it's working like expected !
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] friedsonjm:
I am also using fingerprint with pin and that is working fine.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
Yes, this is not a issue ... right now the big issues it's Instagram, Facebook and I guess also othere apps can't start ... and after I installed a lot of apps when restart the bootanimation run very slowly and it's feels like there is no RAM at all in this device !

EDIT:

Yes, with this inconvenient of registrations of Gapps, I didn't tested them on my build before released... my bad !

Really enjoying this, but I have a couple of issues.

Maps.me won't run (one of my favourite apps), and WiFi won't connect if the SSID is hidden on my router. Once SSID is broadcast it connects fine, but if the SSID is hidden it loses connection.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] earlg100:
I had a similar issue like Sergio.

I came from LOS 17.1 20/12/2020 build with PIN lock in my W09. Dirtyflashed to 26/12/2020 lead to problems with unlocking. I could type my PIN again and again and there was no unlocking performed. So I went to TWRP fileexplorer and renamed the locksettings.DB. after reboot I could set a new PIN and register my fingerprints. Now everything is working.

So maybe you add an advise for those who dirtyflash and use PIN to set the security to "none" before updating to the new build.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
I saw yesterday, the Lite version works for me too.

Ok, I think the issue comes with changing the location of a fingerprint blob ( previously it was on root and on this version was moved on vendor/bin/ ) ...anyway, this issue will not be repeated in future updates !

EDIT:

Please help as much as you can, to detect the issues related to applications that refuse to start . You can take a logcat ( adb logcat > log.txt ) while you try to open facebook or instagram ... and maybe someone with more free time will find on Google some similarities with other devices where these problems happened.

At least I need to know from where comes these issues in order to start to debug them.

Thank you very much for any help !
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] sergio_sant:
I dirty flashed again 26/12/2020 and deleted locksettings.db in TWRP right after flashing. It works now, I could set a new PIN and register fingerprints, it works like expected.

PS. Youtube Vanced root version is working for me (it wasn't in the 20/12/20 release).

I have a strange issue with Play Store - normally, you can swipe from left to right to bring up the 'My Apps & Games' page, and see if you have any pending updates. That does not work now, I have to go to Play Store Settings to get access to that page. I flashed the micro Gapps 12 20 23 version. Anyone else seeing this?
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
Please take a look at this screenshot from here, you should type to the three lines on the left in the search box to switch to My apps & games .... I already tried on my Oppo Reno 2 with stock Android 10 and have the same behaviour!

EDIT:

I guess it's not working like before in order to not be confused with gesture navigation

EDIT:

Ok, on my Oppo it's working to swipe from left to right , but only if you swipe from the top of the screen. Do you tried in this way ?

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

Long, but it works...
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] mOlDaViA:
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 !
