After this my device reports on the next boot attempt "Device has failed verification, may not work properly". but a normal boot can then be initiated by pressing the power button once more. This behaviour is retained unless I start a system update from the dload folder on my external SD card.

Do you have : PHONE Unlocked and also FRP Unlock on bootloader mode ?

EDIT:

I see on my device, USER LockState: UNLOCKED
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] wandro:
As you see in my post #827 I have "USER LockState LOCKED".

If this causes my troubles, how can I avoid it?

EDIT:

The reason for my troubles was apparently: I had unlocked (with DCunlocker) the bootloader when I still was on Android 6:

I have now repeated the unlock process under Android 7, and now I could install twrp and successfully open it using Power+VolUp.

Many thanks for your help!
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
I don't know exactly, but something it's wrong on your device .... first, you should check if OEM/FRP are unlocked and then google how you can solve your problems !

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

Like always, please check OP for downloads.

Changelog :

new security patch : June 5, 2021

new kernel updated to 4.4.268

screenrecorder working now

Thank you for updating, surdu_petru.

I calculated the MD5 hash value.

Is there a problem with 39f4657494e9ca36f4393eb67bf0c3c4 ?
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] Me,You,and Daigorou:
I will flash the latest ROM tomorrow, and I'm using the previous version right now. Chrome still stops when I'm browsing, so I have a plan below.

1: Dirtyflash and use Chrome for checking. If it doesn't stop, OK.

2: If it does stop, I'll flash the latest ROM from scratch.

Anyway, thank you for the update!
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
Yes, dirty flash over previously update and I have 0 issues !
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] cristox:
After installing.latest version it says it is not play protect certified. I followed instructions to register and read the android Id via adb but it says there is no such column.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] Me,You,and Daigorou:
DirtyFlash doesn't boot, so I decided to flash the latest ROM from scratch. To be more precise, it boots up to the lockscreen, but I can't unlock it.

I had the same problem when I dirtyflashed a previous ROM. In this case, if I do the same thing I posted before, it will work, but it's obviously not normal, so I decided to flash it from scratch.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
I don't use Magisk, that's why there is 0 issues when dirty flash from previous update !

if you use Magisk, your issue it's very normal - because the update will replace your patched boot.img with a new one !
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] Me,You,and Daigorou:
Yes, I am using Magisk and Xposed. And it makes me hesitant to send a logcat to you.

I have sent you logcat a few times, but that time I've re-flashed a ROM to a clean state with Magisk and Xposed completely removed.

Now that I've finished the clean install, it's running normally.

I haven't checked Chrome yet.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] LL83560:
Hi, great news this 17.1 with enhancements :)

After installing it, I tried installing the former "addonsu-16.0-arm64-signed.zip" in vain ... TWRP install ends up with error 7 (normal if that package was specific to 16.0 I suppose...)

So, has anyone got any idea how to root it then?
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] LL83560:
other problem : impossible to register the GSF # (android id to get access to google service framework). google registration page does not accept the id.

That looks a nasty one...

Not sure if that's related but I found it impossible to install Gapps nano, it aborted telling me "insufficient storage in system partition" and error 70, so I installed Gapps pico instead.

I have a BTV-DL09.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
If you want root, please use Magisk - it's working without issues.

Nano should work - are you doing a clean install?
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] Hitchi:
yes coming from LOS 15.1 and made a clean install....

installed now with nano gapps

netflix not showing in playstore after registering the device for google services ...

tried magisk hideprops and spoofed the FP of the huawei mate 20pro... safety net passed but with evaltype basic....

any workaround to receive netflix in HD?
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] Vesko01:
Same here, clean install even wiped all partitions, but to no avail.

Update: Eventually, managed to install the pico package.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] Vesko01:
Also, I have another question for the future development of this mod. Does it seam possible, at leas on this stage of the mod development, to go from Widevine DRM security level L3 to L1 in order to watch HD content on streaming platforms like Netflix? Another thing, if you could share @surdu_petru, what are the next changes gonna be, and what are the more exiting updates in the near future going to look like?

That out of the way, sincere thanks to the work you've done for this device so far, bringing this device back to life. Thank you so much!
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] thunderz1:
For Netflix try adding Google Play Services to Magisk Hide and then clearing the cache. Netflix is available in the play store for me with evaltype basic.

Have not tried it but you may be able to create a patched Netflix app that will allow HD without Widevine L1.

If you try and it works please report back!

If I remember I had to install the pico gapps even with a clean install (not sure that matters anyway).
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] Hitchi:
already tried magiskhide with no luck... netflix does not show up...

patching the netflix app seems not possible anymore

anyone has another idea

EDIT: maybe I just have to select another FP code for magisk hide props.... which one to choose
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] Vesko01:
I've edited mine to the Mate 20 Pro and Netflix showed up in the play store. Did you activate the MagiskHide option from the settings? It didn't work for me too, but when I turned that option on and made a reboot it worked.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] Hitchi:
Yes tried the magisk hide and also enabled all the playstore sub-categories

tried the fp of the mate 20 pro but still not showing up and whne I'm installing the Netflix app from a web source it's running but no HD videos

[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] evilhomura89:
Currently still on stock but rooted with greatslon TWRP and Magisk ROM (BTW-W09) - was planning to jump into LineageOS.

In terms of stability, is 17.1 as stable as 15.1 already?

Meanwhile, 15.1 download link is no longer available.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
Yes, sure ... there is no reason from my part to not continue the update for LOS 15.1 & LOS 17.1 !

As I mentioned a few weeks ago, at the moment I have poor internet connectivity at home due to some worked to modernize the internet infrastructure, and starting with September, everything will return to normal !

That's why the last updates of LOS 15.1 & 17.1 were improperly uploaded to hosting sites limited to one month ... all this will be changed with the next updates, updates which will start again regularly from september this year !

Thank you very much for patience !

i have just bought one, BTV-DL09 currently on Emui 5.

Bootloader is locked. I will get that unlocked.

Can you clarify after bootloader is unlocked what are the steps to upgrade to 17.1.

Read through some posts where people have went 15 first...Not clear on what the procedure is or what version twrp i need first.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] duesouth:
My media pad is currently on emmui 5. The keyboard was missing but was able to dowload keyboard from playstore/

Tablet is showing as model number d-01 j and version NRD90m test-keys

Tablet is working fine apart form rotation is now not working. ( using a rotation manager to help with this at present)

Bootloader was unlocked, i get the device waring at the start but i'm pretty sure its locked. Some fastboot commands that i cant run. like flashing twrp again.

I would like to do a couple of things

Upgrade to 17.1 - Can i do this with what have at present after unlocking bootloader. Flash twrp, wipe and install the Ziip?

Will i be able to fix the rotation? Does lineage have asny of dtata files like sensorhub etc...

some guidance would be great on next steps.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] sergio_sant:
I guess rotation does not work because of the test-keys firmware that's been flashed into the tablet. You'll get it to work in Lineage.

I'm not sure how to proceed in your case, it seems you have Japanese model... I think some people has done it before, maybe you could search in the forum.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] duesouth:
The tablet had been converted from JPN version. When I originally got it, it had c100 firmware

The problem is, file downloads for firmware are difficult to get. I did find EMUI 5 which is needed before going to Lineage however it didn't rotate, no default keyboard and it is the test keys.

I can again revert to EMUI 4, the main issue with that is the wifi sucks on it. The speeds drop on it where as on emui 5, the wifi is fine.

I gues im not sure does it matter if its test keys or not. As long as it is EMUI 5 then it should upgrade.

On a side note, on thios build I can no longer access Project Menu,, tried the calculator method which didnt work. No dialler installed by default.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] orangpelupa:
After you use lineageos a d rotation no longer work. You need to flash something back to the original.

Okay, here it is. The reason you have no keyboard or rotation or the other little things that don't work is you didn't flash the whole package. The stock rom comes in multiple parts. There is a hardware .zip that has hardware and localization files in an update.app that is a lot smaller than the main update.app. The testkeys have nothing to do with it not working it is just that it gets flashed by itself by so many people that it is believed to be at fault. I believe the full file set is available with reference and link in this thread. If not I have the three part OTA from Huawei archived somewhere, I just seen it in the last day or so. I didn't realize I still had it, and yes it is from huawei servers when they still updated this tablet.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] Me,You,and Daigorou:
Does your M3 work for more than 3 hours?

My BTV-L0J always powers down after around 3 hours. In stock ROM, I could use it for more than 6 hours.

For future reference these tablets will show unlocked when locked. They get hung between lock states sort of, it will be locked and report unlocked when checking. Will also give orange state warning at boot while locked. I have a Sigma Key that reports it as unlocked while locked. If you think it is unlocked and getting remote: command not allowed, then is is locked or in between. Run your unlock code again anyway. If it tells you that it is already unlocked it's being less than truthful. Use

fastboot oem relock <your bootloader code>

then let it do its reset and set it up again for debugging then unlock the bootloader. The only real way to know is by running the unlock and relock commands. The white fastboot screen when working in fastboot lies also giving red unlocked text while locked.

NTT Docomo accepts orders for battery replacement until the end of November 2023, so I felt a bit hopeful. I like this ROM.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] Me,You,and Daigorou:
And also NTT Docomo will provide OTA until the end of November 2023, so if you have any trouble with BTV-L0J, you can back to stock Android 6 and then update to Nougat via OTA.

However, I recommend using dd command to backup the four partitions: boot, system, userdata, and vendor.

This is because neither Huawei nor Docomo has published stock ROMs for Android 7. Therefore, you need to downgrade to Android 6 and then upgrade to 7 via OTA.

If you have made a backup with dd command, you can easily back to Android 7.View attachment 5418303

The method to bring BTV-L0J back to Android 6 is complicated...

I used DeepL to translate a memo written in Japanese, but it was quite long. So I used pastebin.

I did not try to correct the English text because it was too long.

You can find the files you need by searching here. But you may not find oeminfo.

LineaegeOS is not to change oeminfo, so you might be able to skip that part.

I can't guarantee your success, so please do it at your own risk.
