Hi, I didn't see an appropriate thread for my question so chose one with high activity. I bought a bricked M3 real cheap and it was sold as BTV-W09. When opening tablet I found board ID to be SH1BTVDL09M VER.A RF HF. Did Huawei use parts interchangeable between the two or did I not buy W09 but DL09 instead ? Can confirm no mic on charger port board for LTE. How to determine which device it really is ? Also, would anybody happen to know location of test point ? I've looked what seems like everywhere and have not found anything. I have a SigmaKey but it does no good if I can't connect. Any help would be great and greatly appreciated. Thanks

M3 lite 10 is not booting into TWRP ...

Hey,

I really spend quite a lot hours to get the twrp and the Lineage 17 OS installed but something is wrong and everything I read does not solve my problem. Can some one my help ?

What have I done:

Downloaded all recommeded files and software

1. unlock the Tab (Phone and FRP unlocked on Fast Boot Screen)

2.installed HISuite on PC

3. installed ADB driver

4. started CMD in Admin Mode and installed TWRP ( recommeded Version 3.3.1.-1)

5. rebooting of Tab always end in Huawei Bootloader ... AND from there into TWRP bit there is no menu. Only the start screen of TWRP .... and than nothing happen from this point on ...

Any Idea ? or information needed ?
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
Please read again carefully the info into TWRP 3.3.1-0 !

Your device it's on stock Huawei Android N, so you can't use TWRP 3.3.1-1 nor TWRP 3.3.1-0 !

Edit:

I guess you got it : just install 3.2.0 format data into TWRP and install first Los 16.0, from here you can update twrp and also the Rom !

Just installed TWRP 3.2, Lineage OS 16 and GApps. System boots but hangs in the beginning where the circle goes from right to left. Is this a known issue?

UPDATE: I was a bit impatient. After a couple of minutes system showed me the welcome screen. Sorry for posting too early.

Need Help!!!

Just installed twrp_3.2.0-0, Lineage OS 16 20190822, and GApps Pico. System boots but hangs at the beginning where the circle goes from right to left. I have tried all the forum ROMs and they all do the same thing... This is the first time that I try to install a custom ROM

Nethunter Bah L09

Hello, who ever tried to make a kernel under Nethunter? A friend helped me build on android 10, but it didn't work out. Who ever tried to do under 9 Android?:o
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] technn:
Camera still doesn't work? I need this not for pictures, but QR codes in some apps.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] SaddFox:
Download for lineage-16.0-20190822-UNOFFICIAL-bach.zip doesn't work. I am trying to go from stock EMUI to LOS 17.1. Can I go from stock directly to the latest LOS 16 build or do need to flash build 20190822 first?
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
It doesn't matter which version you use as long as it's based on Android Pie/ LOS 16.0 !

You need to follow the installation instructions from TWRP and Lineage OS carefully and you will certainly not encounter any issues.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] ossizwei:
Yes, you can't save pictures. But often camera works in apps to get QR codes. I'm using it with banking app and SecScanQR app or with Signal for desktop. The only problem is, its working in "slow motion ". You wait ...and wait and suddenly the scan is taken. And than you wait again before you get the result.

For me its Ok because i don't need it daily. I have a Mediapad with BAH-L09.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] pranshuTG:
Hey OP i was wondering how you got the kernel
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] Sillyw4lks:
Hi I just received an untouched BAH-W09. No idea how to unlock bootloader. I've seen that you need to pay to do that. Any solution? Thanks.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] tek3195:
Camera works in landscape with PWR & VOL up top and fingerprint sensor on the right.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
what does it mean exactly ?
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] tek3195:
If you read these threads about and for this device you will see it's history. He put in a metric buttload of work. I'm not looking at version number right now but Huawei dropped it at nougat. You can get nougat kernel source on line but then you would need thousands of hours to bring it to where it is. Go back and look at all of his posts for this device, the number of patches and commits is insane.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] Callor:
Hello, I need help saving my m3 lite 10 mediapad, I'm trying to upload TWRP and I get something from CMD, if I run TWRP, this problem appears. What am I doing wrong? Can anyone help me?
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] tobjas:
Hi, I have this same issue, did you manage to solve it?
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] tek3195:
try it by booting from the recovery partition instead of booting the image on your PC. if you've already flashed it there is no point in just booting the image. We use the fastboot boot command to prevent altering device partitions, obtaining backup and for testing. I've not tried it but don't think you can install zips that will alter the device when booted to an external recovery.img even if it's the same as the one on the device. Try rebooting recovery and see what you get.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] michael-arlt:
Bit late but just read the instructions and you wont have that issue. Its clearly stated to "format data". Its an obvious button in TWRP inside the delete menu. This error is due to the encrypted data partition. Same for @Callor
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] tek3195:
@Callor had an issue with permissions not encryption. He was booting recovery thru fastboot, it could find and read /data but would not grant him permission to read.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
Help please, maybe someone can upload this version "20190822" of LOS 16.0 as I deleted the source by mistake, thank you very much in advance.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] hobelik:
Would be great if someone find it... Im stuck on nonworking 16 because of missing 20190822 version in process.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] hobelik:
Ok. Now I can advice what not to do... No one replayed so i was trying to outsmart process ...

DONT UPDATE TWRP UNDER TWRP !!!

Now tottaly bricked unable to boot even to TWRP.

Thanks for quick response.

Ps.

Also don't start process of updating your device as for now missing most important in process LOS 16 20190822.

[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] gyoshin:
Is this what you need?
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
Yes, thank you very much !

Please, is there any chance you have the first version of LOS 16.0 , the one from July 04, 2019? because I would also need this to add to the OP! Thank you very much in advance for your help!
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
with the help and kindness of our colleague gyoshin , I managed to add the 20190822 version in the OP, if this version does not solve your problem, it means that you need the very first version of LOS 16.0, the one from 2019/07/04... which unfortunately I do not have it anymore.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] marciu:
First method did'n not work for me , followed each step and it will not boot , wish there was some sort of zip file you could flash with stock rom the same way as you get custom roms... anything to get my tablet working ;/
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
Are you able to boot on stock recovery after following first method ? you need this in order to performe a full wipe or the device will not boot on stock ROM !
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] marciu:
First method didnt work form be system boot loops , I can load erecovery but it also doest work form me
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
No, you need to boot on stock recovery, not erecovery ... and there you must do a full wipe ... after that you'll see that your device will bot on stock ROM !

A full wipe in stock recovery it's mandatory in order to encrypt device back ... without this step the device will be in a boot-loop !
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] marciu:
Stock recovery isn't booting to perform the full wipe :/ is that mean my tablet is doomed for good?
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
Until we will find à way to revert to stock, you can use LOS 16.0.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] marciu:
Managed to get back to stock, tried a few different updates from the website you gave me and one of them worked allowing me to boot to recovery and do the factory reset (following method one - mentioned before), I am now back to stock, thanks for all your help :)
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
Nice :)
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] bejam:
Hi surdu_petru , it's amazing to see modern LineageOS on this tablet. I was about to give up on the m3 and buy something else due to lack of Huawei updates. So fantastic work! However I have the standard mediapad m3 8.4 (not the lite version). I am guessing this ROM will not work on that? But perhaps it isn't so much different and you have got most of the way there already. It would be good to hear your thoughts - and if it is beyond scope, perhaps there are also other devels reading this that than can assist (I am not one but happy to be a tester).
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] Peezuki:
Finally, a genius ,who,'s actually taken his time to design a custom ROM for these two brilliant devices! They are both top notch and deserve to be honored in such matter.

If you will take some more time out of your hands to make this ROM even better / more stable, I swear to GOD I will support you! Not as a co-designer of course but as in, donate some money to you!

Keep up the good work my friend!
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
Hi !

As I know, the standard MediaPad M3 has a build in house soc named HiSilicon Kirin 950 ... and the Lite one it's based on Qualcomm MSM8940 Snapdragon 435 !

Unfortunately I can't support M3 not Lite due to lack of source code by Huawei ...

I'm sorry if you're disappointed, but I guess you should buy in the future only devices based Qualcomm Snapdragon if you wanted to install some custom ROMs .

Thank you very much for all your kinds of words :o

And yes, I started development on this device in December 2018, the updated of this ROM was somehow very slowly because I had a lot of work to do with updating the kernel source code ( there is almost 8000 commits pushed manually as you can see on my github kernel source code for Android Pie ) !

Do not worry about it, I will continue to work ( in my spare time ) on this ROM, even though there will be one, none or more willing to install a custom ROM on these tablets :)
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] bejam:
Thanks very much for the response. I guess us M3 non-lite users are screwed after all! Good luck to those with this exciting new ROM for the lite.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] SilentYukiro:
For those who own the the M3 Lite 8.0 with build number CPN-L09 and used this custom ROM, did the performance somehow improved when playing games or when the device is used heavily when compared to the stock ROM? Apologies if this reply is somehow a bit off from the thread's discussion. If this does not suit to the topic at hand, I can delete this post.

I haven't tried flashing a custom ROM on mine since its only been a year when i purchased it and I do not want to risk on bricking it, voiding the warranty (if it still has), nor I have the bootloader unlocked. Now the reason why I'm asking is that I've factory reset the device for around 3-4 times but when playing games (not even graphics-intensive), I can feel the device struggling randomly where I resort on turning on the 'Force GPU Rendering' and have 'Low Resolution Power Saving' just to make it bearable.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] gucio1976:
Thank you for LineageOS 16.0.:o

But when you can go repairs the webcams. They are needed.

Great work for BAH-L09

Thank you very much for your very good work. I installed your rom on BAH-L09 exactly with your instruction. Works since first boot. Now i have all i need, because i dont need camera. Only issue is, that i can't login to my Google account this Moment. But i think that is not a rom problem, because i try to usw microg instead of official Google play. Will test more in the next days and send you feedback in success.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
I'm still working on camera ... I managed to Open Camera on LOS16.0 but for the moment I can't use it because there is a issue with the new /system/bin/cameraserver from Pie wich crash with our camera blobs from some unknown reason !

Thanks !

Please try to use official Google Apps , I have no issue to login on my Google account .

New Update LOS 16.0 !

Hello !

You can download now a new update of LineageOS 16.0 for M3 Lite 8/10 - from OP !

What's news ?

- update compatibility with all MediaPad M3 Lite 8 (CPN) devices .

- fixed sound speakers on MediaPad M3 Lite 8.

- enabled camera ( unfortunately, cannot yet be used for the moment )

Thank you very much to [MENTION=6067782]Lothgar[/MENTION] for testing stuff on his CPN device .... without his help, the CPNs devices would not have benefited from TWRP and LOS !

Best regards !
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] frankieuk:
Thank you so so much! its now working perfectly for me, the only issue i had was not being able to turn the screen back on. sorry i couldn't of helped, not much good with these things. thank you again! very very happy!
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] ossizwei:
microg works

My tab is m3 10 lite BAH-L09 german version with bootloader unlocked. I did a clean install of this rom. After first boot i installed microg zips with calender and contact sync in recovery mode. I installed neccesary modules for xposed framework too for signatur spoofing.

After reboot self test for microg was succesful. Login in my Google account was possible and calender-/contacts sync works.

Today i flashed new TWRP 3.3.1. Reboot into recovery with no problem. Flashing root with Magisk works too.

Dirty flash of new rom of July 27th was possible and after boot all the things i need worked for me. This Rom is great work, big thanks to the developer of rom an recovery and everybody who helps him.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:

Thank you very much for confirmation, I'm happy to see that's working well also on your device :)
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] Lothgar:
I have your model, with this rom the tablet is waaaay smoother. Its just better than the huawei crap.

Obviusly there are still some bugs, but im sure most of them will be fixed, we are in good hands! :highfive:

If you have any questions on how to install or more details just ask!

Is there any way to port this rom for the mediapad m3 8.4? BTV-DL09 device.

Well done!

Greetings from RO!

Edit: Bad question...just saw the answer on the previous page :(
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] 30adi:
Just a stupid question: do you need source codes from any kirin 950 device, or especially from mediapad m3 (non lite)?

https://github.com/hackslashX/android_kernel_hisi_hi3650
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
No, we don't need only kernel source code. Qualcomm provides almost all sources code for msm8940, unlikely Huawei that provide only kernel source code.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] raydlp:
Thank you for this, this rom works well. Better than huawei original rom.

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

You should wait the new update :)

Hello !

I just uploaded a new update of LOS 16.0 ( into OP ), this time seems to be working well on all MediaPad M3 Lite devices !

Same issue with odd colors and several needed reboots on my BAH-L09 too. Sometimes after unlock the screen freezes. Only another reboot helps.

But i like this rom very much . It's more better in use, than Huawei's rom. Thank you for the great work you are doing. I use microg instead oft googles play services. No issue since several days. But without microg or googles play services installed, the rom stops at first boot.

Do you have any plans to release vendor/device/kernel tree (your custom patches)?
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
Yes, the kernel source code is already released as is mandatory on XDA for each custom ROM wich not use stock kernel !

You can find a link into OP.

I used the device tree from here and the appropriate vendor blobs.

And yes, I didn't released yet device/vendor tree because my work here is still in progress and made a lot of modifications every day - but as soon as I'll be able to fix the camera, I'll release the source too.
