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

I might have found issue / limitation

I've tried to install nano opengapps and wasn't able to ,

I'm getting error 70 when I'm trying to install them, it mean not enough storage on system partition ,

I've checked partition size and it is 1920 mb , I don't know if it is some kind of limitation that you had to set such partition size or I have something wrong with my partitions .

After installing pico opengapps only 260mb is left free , is there option for you to increase size of partition in the os img/zip ?
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
Yes, the System partition has only 2GB ... and it's exactly the same size as on Huawei's Android 7.0 !

You can't increase this size so easily ... I can easily increase it in LOS 17.1 when compiling the whole rom, the problem is that the size of the System partition is checked by TWRP, and if it exceeds 2GB, TWRP will fail to install LOS 17.1!

What you want involves a physical change (a partition size distribution) which is harder to do! At the moment I don't have the knowledge to actually increase the size of the Systrem partition, nor do I want to damage users' devices by trying and testing !

EDIT:

I know the problem of limiting the System partition has become more pronounced with Android 10, because much more data is stored here than on Android 8 or 9

EDIT II:

All devices that switched to Android 10, provided 3GB in the System partition only for Android 10 ... from what I saw the vast majority exceed 10GB for the System partition ... we currently do not have even the minimum 3Gb required for the Android 10 operating system !
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] accerian:
Thank you for detailed replay :) I enjoy getting new knowledge :)

I think it would be good idea to add info in 1st post tutorial to use only Pico OpenGapps

And tutorial from sjc0211 regarding device registration for play store :

"

1) Clean Install LOS 17.1 (You should wipe also system/vendor partition using 'Advanced Wipe' function)

2) Extract GSF ID (19-digits) using ADB (You can find corresponding adb command in this thread-search keyword: sqlite3)

3) Register GSF ID at https://support.google.com/android/answer/10248227?hl=en#zippy=,device-isnt-certified

4) Wait ~15 minutes with network connection

5) Disable 'Google Play Services' & 'Google Play Store' in Device Settings

6) Reboot Device

7) Enable 'Google Play Services' & 'Google Play Store' in Device Settings

8) Launch 'Google Play Store', if this method worked for you, Log-in screen will appear.

"

Only question: any chance to get the homebutton working? i don´t like either the 3 icons nor the gesticulure. i liked the control on the lower firmware of the mediapad.

Hi i have an issue. And i have tried all possible methods to fix it.

Onstock rom auto rotation and other sensors were working fine but after flashing lineage os. Nothing is working.

No gyro

Auto rotation not working.

I have tried flashing again and again.

But nothing happens

Hi surdu_petru,

Thank you for your effort and work on keeping this device alive! :) I have recently installed LOS 17.1, and i see that the FlipFlap app is missing, which is responsible to lock the screen when I close my magnetic cover. Could you please make a build of it and maybe share it? As far as I see you use your own signatures, and my AOSP test key build will not install due to incompatible signatures.

Thank you in advance!!
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
Hi !

Do you tried to enable auto rotation ?

Hi !

FlipFlap app it's not working that's why there is no app !
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] R0peE:
Thanks for the quick reply. Is it due to an app issue? As far as i see the HALL sensor is working correctly in 17.1

Hey, surdu_petru what do you think, will you be able to do any more updates for this ROM?
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] baalagee:
Sir i think you didn't get my point. I meant to say auto rotation is not working

I mean i have enabled auto rotate but it doesn't work

Screen doesn't rotate

And camera is making issue. If i switcht o front camera and capture a picture it won't save and camera app hangs

And than app shows an error another

I have enabled auto rotation but it doesn't work. On any version. Screen doesn't rotate. And camera has caused an issue . When i switch to front cam and take a picture it isn't saved and camera app gets crashed. And after reopen it says camera is in use by another application.

And i need rollback files but i can't find.

My device was on version b311 i think. But it isn't available anywhere

I need rollback package for BTV-DL09C100B311

Where can i find it
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] Me,You,and Daigorou:
I restored to Android 6 in March and did up to 7 via OTA.

I have done many times the same steps and have never been required to insert the SIM card, so I find it very strange.

However, there may be something wrong with the docomo.

In March of 2021, there was a problem with docomo's update server and we were unable to OTA. At that time, it took about a month to resume.

Anyway, OTA is possible until the end of November 2023, docomo says.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
Unfortunately, official support has ended for LOS 17.1 Android 10, which means there will be no more security patch updates.

Since @accerian has found a solution to enlarge the system partition so that we can later install any of the GApps packages, I will be back soon with a new update.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] friedsonjm:
Yeah!
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] friedsonjm:
Surdu, I don't know if it is helpful, but there is another ROM installation method that uses flash-all.bat via fastboot instead of TWRP/Recovery that may be useful. ProtonAOSP and others use that method. I'm wondering if it might help us make the jump to 18 ?
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
I don't think it's a recovery issue, I tried to install LOS 18 on my device, but unfortunately I didn't find a way to update graphics blobs to Android 11 in order to be able to boot ! Not to mention the other drivers that also need to be updated to Android 11, and I don't see any solution for that at the moment.

To detail a little:

There are some things that are harder to access / (controlled) because they became dynamic in Android 11 compared to Android 10 where those things could be controlled through a file - this is the main reason why no driver in Android 10 is recognized in Android11 (and a solution is very hard to find and involves more of a hack in our case, but unfortunately as I said, I do not know at this time how I could do it)

I am sorry if i ask the wrong question here. I just snagged a Dtab d01j. I am not trying to install lineage OS first. I wish to convert to global ROM Marshmallow

- I need to unlock bootloader first

- Install TWRP

- Flash global zip

If anyone can show me more specific steps. - which to flash. Thanks a lot.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] Me,You,and Daigorou:
I am not a specialist, but I don't think you can flash Huawei stock ROMs with TWRP.

According to a post on this site, it appears that ROM for M3(Android6) can be flashed without BLU. But autorotation will be disabled.

First, flash a UPDATE.APP (intermediary package) on Android 7, then flash a M3 ROM (Android 6).

ALL file links and detailed instructions are written in Japanese in this PDF.

However, if you do BLU, you can flash a ROM for M3(Android7) in almost perfect condition with autorotation enabled. The method is complicated. I may or may not write the method on Pastebin someday. Because I will spend a lot of time writing English and proofreading it.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] trunglevt:
Tks for your article. I am still on Docomo Marshmallow. I tried upgrading but it keeps saying cant check Downloaded files. Update failed Reboot System.

[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] donuts100:
First tried version 15.1 on BTV-W09.

Version 15.1 on stuck at boot.

boot animation that over and over.

Ok, so I swap to 17.1 and try again (with twrp 3.3.1.1).

It has been successful and works well so far.

17.1 It seems to be fast and low battery consumption.

The device now has a long life.

Thanks to surdu_petru.

-----------------------

my experience.

twrp 3.3.1.1 goes into boot loop when usb MTP mode is enabled.

(I don't know if this is a bug or a problem with my device)

I disable twrp MTP mode before usb connection.

After entering twrp, connect usb and re-enable MTP mode.

I can't see "live view" of my seek thermal (USB thermal camera) app.

However, the captured files are saved correctly.

This app will only run if you allow access to the device's camera.

I think this is a problem with the app itself and will be fixed once the device's camera works.(or a mock camera that outputs blank data)

As already known.

Not authenticated by Google (can be used with Google apps by manual registration). If you're using a strict app(detect rooted device), it won't work.

This is a "Huawei device".

Once installed, it is difficult to go back, so you have to be careful.

i haven't been able to figure out if this has been asked already or not but can i lock my bootloader again after installing the 17.1? the unlock, and install process went smoothly, but i had ended up using nano gapps because the first one i tried it said was too big. now tho on reboot i get that same bootloader unlocked message, and i'm wondering if locking the bootloader will make that message go away, and not break anything.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
No, you can't !

bootloader unlocked message it's very normal and will not break anything ... it only warns you that the bootloader has been unlocked and the phone is less secure, just ignore this message and everything will be fine !
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
it is possible but it is a bit more complicated, I will only give you the solution in general: install TWRP with data decryption support so that you can make a backup! then you have to install LOS but at the same time you will need another TWRP (the one indicated in LOS)! If you want to go back to the original backup, you need to do the following: Install stock EMUI firmware through the dload method with update.app placed in the dload folder, then install TWRP back with decryption support and restore the backup back to your phone!

Warning:

This backup should be saved on a MicroSD card, as the internal memory will be formatted when installing LOS!

Is there any solution

I have used dload method to rollback fo stock from lineage.

It updated to 100% than bootloader got locked but device was in a bootloop than i unlocked bootloader again.

And after restart it's in a bootloop again and fastboot isnt working. I think now the only solution is to open the back which is almost impossible for me.

Hello!

When I was using this rom, power drops abnormally fast. Then, I checked the cpu usage list, and I found out gms and surface finger are always using a high percentage of cpu. I also checked out the batter usage in settings, and it shows up with a high battery use from the screen, I wonder if this is normal or not and if it isn't, is there a suitable solution?
