I wanted to thank the developer! Amazing job!!!

I'm really impressed with the perfomance of this device and can't stop to ask myself why with the Huawei stock ROM my tablet was so slow.

Also, wanted to ask to the rest what setting did you configure in V4A. This tablet has great speakers and couldn't get them working nice again.

What other Magisk modules is people using on this tablet?

Thanks surdu_petru , gave my tablet a new life!
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] mikwii2000:
Can I dirty flash this ROM over the old Lineage OS with Android 9.1? They are very similar and the developer is always [MENTION=2335078]surdu_petru[/MENTION]

P.S: thank you for your great roms!

LOS 16 or 17 ?

Hi there,

I have just found this thread, I have a m3 lite 10 with stock ROM.

Which version do you recommend to install 16 or 17 ?

Best Regards,
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
You can't install directly LOS17.1, first you need to install LOS16.1!

Tk you very much for the comment, looks like I have to read the instructions :D Next weekend i'll move forward into it.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] pipolas:
Hi,

First of all, thanks for the amazing work.

The tablet was in a box for 1 year, I'm using it again thanks to your rom : so much more responsive than it was before.

Seems everything is working except camera... And I do have huge sleep battery drains.

I rooted the tablet, gonna give a look at cpu usage while in sleep, and get back to you.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] pipolas:
Hi,

So i had a look, and it doesn't seem to be a cpu deep sleep problem.

I went to bed à 3 am, tablet had 69% battery.

I woke up at 9am, tablet was 62%..

CPU was offline for 97,4%

CPU was 960 Mhz for 2,16% (23mins)

CPU was 768 Mhz for 0,37% (4 mins)

I think i will have to look about kernel wakelocks ?

Thanks !

Hey surdu_petru thank you for your work with this ROM.

I have installed your LOS16 in my tablet and I was wondering to update to this but can I dirty flash LOS17 over your LOS16
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
I don't know, I never tried in this way, but you can try and let us to know !

EDIT:
[MENTION=7627912]#marcg#[/MENTION] thanks for your donation !

I hope to re start to work on this device in a few weeks :)

Hi!

Video camera it's working and you can record a video ... I honestly didn't try if it works on facebook or skype, but I guess it should working ... or maybe someone which already tested can answer to you !
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] joff1234:
Sorry...

When you say:

What does it means...?

Thanks.

Hello

I installed the rom, gapps and magix but on magix manager safetynet is in red?

and adaway can't make a host file always error message logcat file

can you help me

thank you in advance
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] morgan7676:
adaway require systemless hosts module in magisk for working well!
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] Kagum:
Hey,

Made a dirty flash over the last Rom from 31/03.

In the last rom i had problems with heavy battery drain.

After 24+ hours of usage i think the battery drain problem has gone. :svetius:

Otherwise I did not notice anything serious.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] ossizwei:
After intallation of rom, gapps an magisk you must activate magisk systemless host in magisk settings. After activation reboot is required. Tap after reboot on adaway app... and wait a little bit. Magisk must ask you to allow root access for adaway. Grant root access for the app and adaway hosts files will be created.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] frely:
Thank you ossiswei and morgan7676 adaway ok

Bootloop after install (can still boot into TWRP luckily)

Hi Surdu, I have a few problems on installing LOS last update on TWRP 3.3.1-3 on my CPN-L09 WiFI+LTE - No problems with LOS 16 and Pixel experience, instead here I get a bootloop after the rom has been flashed. Anyway, my goal is to get a custom rom with security patches updated at least to 2019 (and maybe gestures) and to pass ctsprofile test on magisk, because I need to watch Netflix on this tablet. I already tried changing the fingerprint with a certified one using Magisk Hide props module, but that's a story for another thread, maybe
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
Ok, I guess you need to make a clean install in this case ... so, after you already properly formated data on TWRP 3.3.1-3 like it's described in the same thread, just reboot device again from twrp to twrp and wipe all what you see on Advanced Wipe apart Micro SDcard :

So, you should wipe : Dalvik/ART Cache, System, Vendor, Data, Internal Storage, Cache & Android Secure ... after that reboot again from twrp to twrp and make a Swipe to Factory Reset ... right now you can start to flash LOS 17.1 & also Gapps if you want !

Good luck !
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] RyanKingLion:
Unfortunately I've just gone through this, multiple times to be honest. Wiped everything except SD Card, install the zip (tried also without GApps) and then wipe cache and reboot. Bootloop. I can't figure out a reason to this. I tried LOS 16 and Pixel experience to see if they had any issues, but they work perfectly so I guess it can't be depending on my device, but other people here seem to have succeeded

EDIT: I'm trying to start from flashing the recovery again, will let you know soon

EDIT h. 07.20 PM: Still failing to boot, no success
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
If LOS 16.0 & Pixel are both working without issues then there is no reason to not working LOS 17.1 on your device !

Try to be more attentive to details, I still think you are taking the wrong step somewhere .... you should start with twrp 3.3.-2 & LOS 17.1 without Gapps and format data into twrp without following the special steps for formatting /data, as they are only for twrp 3.3.1-3. Maybe you missed to reboot device from twrp to twrp after data was formated or something like that ... because I see no reason to enter the bootloop ...

Also, make sure that /data file system it's "f2fs" on TWRP because with "ext4" the device will not boot !
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] RyanKingLion:
Then I can see the issue - I didn't start with 3.3.1-2! I flashed 3.3.1-3 before installing LOS 17.01 (stupid myself, although I think if that's the problem, maybe you made a mistake by writing "install new TWRP 3.3.1-3" in the first post)

I'm trying now and I'll get to you soon!

EDIT: for the moment, it still has the same problem. I'm now on TWRP 3.3.1-2 and yes, data is f2fs - I've done as you said:

1) flash recovery

2) boot into recovery and format everything except SD card

3) reboot into recovery and wipe data

4) Install without GApps

Hello

Did you fix problem with screen rotation after screen lock?
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
Yes, sure .... I guess I forgot to specify into the changelog :)

I already installed from scratch all my work into a new device ... a few days ago.

So, in short what I did: unlocked bootloader, installed twrp 3.2.0, format data & reboot to twrp, here I did a full wipe and installed LOS 16.0

On the LOS 16.0 with TWRP 3.2.0 I updated twrp to 3.3.1 and installed with a full wipe LOS 17.1 !

Finally I update TWRP to 3.3.1-3 , format data for encryption, reboot device from twrp to twrp & reinstalled LOS 17.1 with a full wipe !

Everything went perfectly without any errors .
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] RyanKingLion:
I've followed all your steps (again) and here's what happened:

Everything works good so far, LOS 16.0 booted, then I rebooted into fastboot and flashed 3.3.1-2

After this, I get bootloop as soon as I reboot into system. Needless to say I haven't flashed 3.3.1-3 yet.

Now: I may be wrong at some point, but I can't see where :confused:
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
Only TWRP 3.3.1-0 must be flashed while you are on LOS 16.0, twrp 3.3.1-2 & 3.3.1-3 must be flashed after you have installed LOS 17.1 !

You shouldn't install TWRP for Android Q while you are on Android P .... You can update twrp only after your device was already updated to LOS 17.1 Android 10/Q !

EDIT:

Stock EMUI -> TWRP 3.2.0-0 -> LOS 16.0 -> TWRP 3.3.1-0 -> LOS 17.1 -> 3.3.1-2 -> 3.3.1-3 !

EDIT2:

After you successfully booted to LOS 17.1, you can update TWRP from 3.3.1-0 directly to 3.3.1-3 and format data here for encryption ! ( I already tested and TWRP 3.3.1-2 can be skipped )
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] RyanKingLion:
No way I can boot into LOS 17.1, even with 3.3.1-0 :crying: even after wiping thoroughly and rebooting, and wiping again. It's like the problem is in the LOS 17.1 zip, but I've already downloaded it three times :(

EDIT: one more issue came upon after this: can't boot into recovery anymore - device keeps bootlooping no matter how much I keep pressed vol+

EDIT2: managed to boot into 3.3.1-0 again, waiting for your advice.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
Let me try to check to boot on LOS 17.1 with this last update from TWRP 3.3.1-0 ... anyway this is what I did a few days ago , but I guess I used a older version of LOS 17.1 , I'll confirm in a few minutes !

EDIT:

Yes, I can boot on this last update of LOS 17.1 with twrp 3.3.1-0 !

I'll update for you a older build of LOS 17.1 from 31/03/2020 maybe you can boot on this version !

EDIT2:

I'll let here a link to download this older version of LOS17.1.

BTW, if you still can't boot on LOS 17.1 even with this older version, tomorrow I'll upload a new build with adb enabled by default ... so after you 'll install the LOS 17.1, you'll need to connect usb cable and take a logcat on boot, to be able to see what's wrong on your device. So you need to let it to boot on bootloop with USB cable connected and in this time you should take a logcat in this way :

after 30 seconds, disconnect the cable and send me this file via PM ( this is for tomorrow in case you fail to boot on the version from 31/03/2020 )

Thanks for your donation :)
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] RyanKingLion:
Thanks a lot! I'm trying to flash it on 3.3.1-0 as soon as I get some more battery power as the tablet is now at 3% ^^

For the moment, I downgraded to LOS 16 which booted perfectly as usual :cool:
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
Yes, sure ... try to flash LOS 17.1 with at least 70~80% battery :)

lineage-17.1-HuaweiMediaPadM3Lite_2020-03-31.zip

Copy this ROM to MicroSD Card ... got to twrp 3.3.1-0 & FORMAT data -> yes, then reboot to recovery , wipe all ( system, data, vendor, cache & dalvik ) and also wipe factory reset ... right now you can install only this ROM without Gapps to see if it's boot on LOS 17.1 !

Good luck !
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] RyanKingLion:
Sadly, it still doesn't work - I guess it's an issue with my device then.... BUT there's something interesting I noticed: when on LOS 16 I tried to reboot directly into recovery holding the classic power + vol+ combination.... Guess what, it went in bootloop. Now, I've discovered that when it goes in bootloop I can access TWRP only by holding all of the buttons together at the same time... Maybe it can be of some help to you the fact that the bootloop somehow showed in LOS 16 too
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] pasha4ur:
You should add such detailed info about installation and encryption processes to 1st message in this topic. In 1st post there is no info about installation 16 before 17.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
Are you sure ? What does it mean to you :

ROM Firmware Required: LineageOS 16.0
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] csjjpm:
So I'm having the same problem as RyanKingLion. I have TWRP 3.3.1-1 and had an earlier version of 17.1. I installed the newest 17.1 2205 and after reboot it was stuck in a bootloop. The vol+ didnt work but tried Ryan's method of all buttons and TWRP loaded.

What can I do to correct? Do I go tback to an earlier version of OS?
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
Ok, I need logcat to check what's wrong ... I'll start now to upload a new LOS 17.1 with adb enabled by default to be able to take a logcat on boot .
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] csjjpm:
I tried this (couldnt find 'wipe factory reset' in TWRP) and still stuck in boot loop after flashing 2020-03-13.zip

[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] RyanKingLion:
"Wipe factory reset" is located in the slider inside the "Wipe" section in TWRP - Just tap on "Wipe" and then swipe from left to right on that

Hope this helps - maybe try again and let me know if you solve - For what I've seen so far - you can exit bootloop by pressing all of the physical keys (vol +/- and power) altogether
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
Here it is :

I think you weren't paying attention or you didn't understand :

I said that now I have started to upload a new version of LOS 17.1 with adb enabled by default - and you'll need to take a logcat ! After that you should send me via PM your logcat to be able to check what's wrong on your tablet :)
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
Here is the same LOS 17.1 from 22/05/2020 with adb enabled by default ( means that this will let you to take a logcat when device boot )

Please, [MENTION=4423419]csjjpm[/MENTION] or [MENTION=10835863]RyanKingLion[/MENTION] install this new version into TWRP 3.3.1-0 and send me a logcat via PM .

New Update !

Hi !

I just uploaded a new update of LOS 17.1 for M3 Lite 8/10 into OP !

Changelog :

- fixed boot on Chopin devices ( CPN )

- kernel updated with new patches

- ROM based on the latest sources of LOS 17.1 !
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] RyanKingLion:
Sorry Surdu... On my device this is still causing bootloop - maybe the issue wasn't that one. I'll be waiting for any news from you
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] spicysomtam:
It might be worth updating the first post that those who are coming from Huawei stock firmware should install LOS 16.0 before upgrading to 17.1. If this had been on the first page it would have saved me alot of frustration and googling trying to flash a non stock firmware. Also include the links to the LOS 16.0 download page.

Other than that, 16.0 looks good, and much appreciate the work of the developers. I'll get round to 17.1 upgrade when I have time.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
It's already stated in OP, you just have to read everything carefully !

On your last dmsg.txt I saw that the device is trying to access a firmware of touchscreen from vendor/firmware/ts/ ... and with this ROM all touchscreen firmwares was added back ! Did you wiped Vendor on TWRP before to flash this new Update ? If not, try to wipe it and flash once again, thanks !
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
In the attention of [MENTION=4378203]vocyber[/MENTION], [MENTION=10835863]RyanKingLion[/MENTION], [MENTION=4423419]csjjpm[/MENTION] and all CHOPIN (CPN) users - you should have informed me as soon as you saw that the new update to LOS 17.1 no longer boots on your device - now it is too late as there is a loot of new commits on kernel, device tree or vendor blobs, so I can't guess which new patch/commit create this issue on your devices !

The LOS 17.1 it's working well on BACH ( BAH ) devices and I assumed it works just as well on CHOPIN ( CPN ) devices as I can't tested on this one ( I have only a BAH device ), and also no one complained about issues on CPN devices, as soon as I released a new update !

If you update your device every 3 months ( and not on each new release ) , I assume that you are not currently using your device and support for these devices will be removed.

I'm sorry, but I can't spend now a week or so to check what it's wrong on your devices, if you can't update regularly your device and keep me up to date constantly with your issues on your devices.

As I already told you, I don't have your device, so in conclusion : the proper functioning of your device depends only on you by immediately reporting the issues that appeared in the new update, but if you report an issue after 2 months this is almost useless.

EDIT:

Please, report if you can boot on the last LOS 17.1 after installing this new boot.img . Thanks !
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] vocyber:
install LOS 17.1 first then flash boot.img using fastboot?
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
Yes, first install the last update available of LOS 17.1, then on TWRP you can install boot.img by choosing install Image -> Boot partition, or via fastboot : fastboot flash boot boot.img !
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] vocyber:
same happen. boot loop after (Your device is booting now screen). didnt get to LOS boot animation
