Thanks @surdu_petru for your work! I am coming from a fresh emui install with the BAH-L09. I managed to use TWRP 3.2.0 to install LOS 16.0.

But I am wondering were do I get the LOS 17.1 from that you mention in the instructions that needs to be installed via TWRP 3.3.1.-0:

"0. LOS 17.1 must be installed via TWRP 3.3.1-0"

Thanks for your help in advance!
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
Happy New Year !

yes, I finally switched to fiber in December 2021 - I feel like I live in a third world country !

Hello !

Do you already updated your device to LOS 16.0 before to switch to LOS 17.1 ?

Into LOS 16.0 thread it's state clearly when you are able to install the TWRP 3.3.1.0 !

Good luck !

PS:

( the instructions are quite simple, everything is for you to be very careful with the installation steps : From Stock -> LOS 16.0 -> LOS 17.1 , and also check TWRP installation instructions at the same time with LOS installation instructions )

EDIT :

If you had been careful, at the bottom of the OP, I wrote clearly what version of Android you must have already installed on your device before switching to LOS 17.1

ROM Firmware Required: LineageOS 16.0 Android Pie
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] TheRealFlorian_:
Thanks Surdu for your fast reply. I managed to install LOS 16.0 on my device. What I am now missing is the file for LOS 17.1 that you mention in the instructions: "0. LOS 17.1 must be installed via TWRP 3.3.1-0"

I am assuming that it is not the one that you mention in this thread: LineageOS-17.1-HuaweiMediaPadM3Lite_2021-06-19.zip or is it? If so I am would wonder why I would need to install the same image twice.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
Yes, the ROM ( LOS 17.1 ) has the name in this case : LineageOS-17.1-HuaweiMediaPadM3Lite_2021-06-19.zip !

No, you don't need to install the image twice, just once, as I explained above:

Stock Huawei ROM -> LOS 16.0 ROM -> LOS 17.1 ROM !

EDIT :

I think you're talking about updates, right ? ... if so, then you need to install a new ROM ( LOS 17.1 ) whenever a new one is available !

Hello !

After a few months, I'm back with a new update for our devices of the Lineage OS 17.1 based on Android 10 !

Changelog:

update of the system security patch : December 5, 2021

This new update has been previously tested on my tablet by a dirty flash ... everything seems to work correctly and without errors, at least on my device.

Thank you very much to all of you for your patience !

@surdu_petru

I am using CPN-W09.

I am trying to install Stock rom -> LOS16 -> LOS17.1.

However, when I install TWRP 3.2.0.0, I get a "Permissiom denied" error, and when I install LOS16, the boot animation loops and nothing works.

Please help.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
That's because you didn't format data !
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] milkute:
Thx!

No more "Permission Denied"!

The installation went well, but the boot animation is still looping...

I'm getting the error "Failed to mount /cust (Invalid argument)", is this related to something else?
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
Maybe, I don't know what you did on your device, as you didn't pay attention for Format data, I guess you missed something else from Installation instructions
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] milkute:
I bricked it once.

I think I may have done something then...

I tried to follow the installation instructions, but it just doesn't work...

Is there anything I can find out by looking at the logcat?
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
You can try to start installation from scratch, just format data & wipe all into first twrp to be able to boot on LOS 16.0. So flash the first twrp available for this device , wipe all, format data , reboot device, connect USB cable to transfer the LOS 16.0, and now I guess you'll be able to boot on LOS 16.0 ( don't need to flash Gapps for Android Pie).
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] milkute:
I'll try it now, thanks.

Perhaps I need to use "linage-16.0-20190822-UNOFFICIAL-bach.zip" for LOS16?

This is the download link that isn't working.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
No, it's doesn't matter what version of LOS 16.0 you use
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] milkute:
okay.

I did what you told me to do, but the boot animation keeps looping. :(
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
A few posts back there is someone which managed to go back to stock Emui, maybe you can check his instructions to install stock Emui firmware and start after that to reinstall twrp & LOS from scratch.

Edit: did you checked in fastboot if bootloader & frp are sure unlocked ? Maybe that's why you're device not boot
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] milkute:
Thank you!

I'll try.

I want to use your wonderful ROM, so I'll try my best.

Hi. I'm having a problem flashing the latest firmware. This happened with the last one too. I am currently on 20210214 and when I flash either 20210513 or 20220104 I am stuck in a boot loop from the bios screen.

I'm doing a dirty flash. I also had a problem with opengapps saying that the architecture was not the right one but I've been using x64 as always.

I have reverted back to 20210214 now and everything is still there, data and apps etc.

Any suggestions?

thanks

[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] gyoshin:
Dirty flashed, everything works fine. Thank you for your update!
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
You can try to backup your good configurations of 20210214, then wipe all into twrp apart Internal Storage and flash the last update without gapps to see if your device boot !
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] csjjpm:
Annoyingly the backup has killed my microsd card! It is no longer recognised by an android or windows device. As if it doesn't exist :-( It is a Kingston 32GB card which seems to be broken now.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] csjjpm:
Does anyone have a copy of 20210214 that they could upload somewhere for me? In case I can't get the latest to flash now?
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
Hi !

I usually use the phone's memory to back up, and when I install an update I do it via dirty flash, and when I want to flash other ROM on clean I'll wipe all into advanced wipe aparat Internal Storage and also MicroSD card if you have one inserted, in this way the backup will not be wiped !
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] csjjpm:
Ok, thank you. I'll backup into internal storage and then not wipe that bit in advanced wipe. I'll let you know how I get on.

Hi

Just to be sure, "dirty flash" is copying the image on the device and use TWRP to install it ?

That's it , or am I missing some steps ?

Thanks

PS: I'm in LoS 17.1 june 2021 release

[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
"Dirty flash" it mean that you shouldn't wipe anything before to flash the new update, but you should wipe only cache/dalvik right after the update was flashed, anyway there's a option in the left side of TWRP ( wich you should select it ), after you flashed the new update.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:

No, unfortunately it doesn't work on your tablet, because you have a device based on the HiSilicon Kirin 659 chip.

You should visit the ROMs compatible with this chip such as HUAWEI HONOR 9 LITE, HUAWEI HONOR 7X or HUAWEI P20 LITE - all these devices have dedicated development sections here on xda, and it would even be advisable to ask directly there, maybe someone will be able to help !

Now go back to the LOS 16.0 thread and start all installation from scratch , you shouldn't bother with update of TWRP or LOS untill you can't successfully boot on LOS 16.0

Would the below be correct?

2. Install Magisk via TWRP

3. Reboot

Is anything else needed like GApps?
