Sorry, I should have given a bit more detail. It was a clean install with no issues about three days ago. Today I was using the tablet as a Roku remote every couple of hours. When I picked it up to use I seen the last part of boot animation, homepage thru lockscreen and then back to boot animation. Been using off and on for the last three days which was good length of time for mine as I still get random reboots to e-recovery. The erecovery reboots don't require any action for recovery, just reboot button from erecovery menu and it boots. It never does that while I'm using it, I always find it in erecovery when powering the screen on. This was different from random reboots as this one was looping while the others boot on first try. I pulled the logcat when I did to try and capture what was happenning then. Couldn't get one any other way, the whole loop is about a 3 second cycle never breaking adb connection. If I had tried a clean boot, logcat would have done no good for current issue. It was not an installation error or a normal boot issue, it was UI issue over 72 hours in use. Anyway I tried wiping dalvik in twrp and got almost thru device setup and it done another UI restart. Settings to that point were still there, wifi still connected and in the process of restoring apps. Finishing setup with fingerprint and got another restart. Went ahead and booted recovery and wiped for factory reset. It's running again like normal, just don't know haw long that will last.

Had some surgery, so I was stuck at home for the last few weeks. Decided to root my device BTV-W09 today. Took an hour or so, but got it all done. Working great!!! I really want 17/10, but thought this would be good practice. I'll definitely donate once 17/10 gets more stable.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] Joe3Stix:
First of all, THANK YOU! to @surdu_petru and all the others that have contributed to this effort! Now that my BTV-W09 is running this build, it's actually usable again!

I'm trying to disable vibration (haptic) during typing. I've turned off the switch in settings, as well as the vibrate on tap switch, but the only way I've been able to completely disable this is to put the device in "Do not disturb (total silence)" mode. Am I missing something?

kernel updated to 4.4.130

fixed microSD format issues

partially fixed Hardware video decoder by using Huawei video codecs

set default cfq ioscheduler instead raw
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] friedsonjm:
Hi, I was surprised to see that you updated 15.1 as I thought they were not enough users to continue updates. Are you going to continue updating 17.1? If not, you know if it is possible to use the TWRP from 17.1 to restore a 15.1 backup?
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
If you didn't backup product partitions using twrp 3.3.1-0, then you can use twrp 3.3.1-1 to restore LOS 15.1 !

EDIT :

Yes, sure ... I'll continue working on LOS 17.1 ... I just updated LOS 15.1 only because I didn't want to let this ROM unfinished !

Peoples have now a viable alternative to stock Huawei EMUI by using LOS 15.1
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] friedsonjm:
So you are stopping development of 17.1?
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] Me,You,and Daigorou:
I am now using LOS17.1, and I am content. I appreciate the update LOS15.1

It's more stable than LOS17.1, Thank you for giving us the chance.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] accerian:
Wow! Surdu_petru you've made it !

Now YouTube works without a hitch with 720p60 and 1080p60

After using magisk hide and changing props to mate 20 pro Netflix installed from play store and I can download inside app without an issue

Antutu for first time went through without an issue

GPU performance jumped to over 25K

And 3Dmark is now showing that this build is fastest build ever

ATM tablet is supper snappy and every thing works nice

As always thank you for your superb work
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] thunderz1:
@surdu_petru Thanks again for the continued support and amazing work with this ROM!

The latest build is working well except I am experiencing the previously reported problem connecting a Bluetooth keyboard. Is there any workaround or can we help provide any further information? Thanks again!

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

I'm glad to see that youtube it's working without issue ... and this is due to the fact that I finally managed to use the stock codecs from Huawei.

On the other hand I guess this will be the last update of LOS 15.1, as there is low used/interest here ! Only six users still use LOS 15.1 according to the last two updates - a few more posts ago I stipulated exactly under what conditions LOS 15.1 will be updated monthly with the latest security patches - for now that condition is not met, and due to low interest, unfortunatly this ROM will not benefit from any update in the future !
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] MVelte:
Thanks a lot for the effort you have put into keeping this fantastic device up-to-date!

I fully understand your plan to move on to LOS 17.1, yet with the camera being usable for taking videos I still prefer this version.

Can you imagine a working camera in LOS 17.1 for our device in the near future?

Best regards and keep up the good work
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
For me there is no problem to continue updating LOS 15.1 each month with the new security patch ... as long as the condition placed in an older post will be respected !

I can't spend my time building & uploading a new update only for 3 users which still use LOS 15.1 ! Please look the previously post where I released the last update of LOS 15.1 - and you'll see that there is only 3 users which use this ROM ! You will also see in the post where I launched the penultimate update, there are only three users who use this ROM.

About camera working on LOS 17.1 ... it is too early to give you a definitive answer !
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] ralawa:
Thank you @surdu_petru for your great job. I'm using your ROM since only one week and I'm very happy to see my tablet working well again.

How do you know how many people use your ROM? Is it based on number of likes of your post? I'm not sure It reflects reality. Maybe, number of downloads is more true.

Regards.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
You may be right, although many may install the latest update and then return to stock , so in this case the number of downloads are also irrelevant.

As you can see I didn't ask too much efort for you all that still using LOS15.1 ( I did not ask for donations, I did not ask you to post at least a few words about the new update of each user - maybe time will not allow this and in this case I agree with you )

I just wanted every user who still uses LOS 15.1 to leave a mark on the last update post, to be easier for me to track.

Thank you very much for your understanding !

EDIT:

The same policy was applied on the MediaPad M3 Lite 8/10 (Snapdragon version) of LOS 17.1 - and this is due to the fact that I no longer use this tablet and I could give up any time to release new updates.

But as you can see here on the last update ... I can easily see that at least 12 more users are still using this ROM, so they deserve a new update.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
Please give me some more time, I'm very busy these days , and the little free time which I have will be dedicated to LOS 17.1.

I'll send a PM as soon as I'll be ready to help you ... Of course I'll just try, I don't promise to find a solution for sure. Thanks !
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] thunderz1:

So, please check/read more posts right from the beginning, thanks !
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] friedsonjm:
You may be able to help the developer by pulling a logcat. That can be done via ADB, or using Logcat Reader app, which allows you to download it. Then zip up and post for review.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] floflunse:
Flashed today and works like a charm.

I can also confirm that Youtube videos play smoothly even in 1080p60.

Hm, strange was running the November version for weeks now and just wanted to update to the new version.... dirty installed the ROM and wiped Dalvik and Cache... now I'm stuck at "encryption unsuccessful" during the first boot

any idea without format? I don't want to loose the data
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
If you have BTV-W09 you should try to flash also the new boot image for your device, because after your issue it looks like you are still using an old kernel where the encryption it was enabled .

EDIT:

On older releases like the one you use it, encryption was enabled in kernel but disabled in fstab, and on the new builds, encryption was disabled in kernel & enabled in fstab. If encryption is enabled in kernel & also in fstab you will get the same issue like you have right now !
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] Hitchi:
no it's a BTV-DL09.... is there also a new boot image available for this?

Kernel on current aosp is 4.4.66-oreo

any way how to install the new version w/o having to configure all my apps?
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
I guess there was a major upgrade of the kernel from October to January and in this case a clean install is needed !

OK... I followed all the steps, put boot_btv-w09_2020-04-29.img in boot partition, tried to install GAPPS and got the same incompatible error message. 'THis GApps pkg is for Android 8.1.x ONLY Please download the correct version for you ROM: 9 (SDK 28)

Now, here is what is interesting... when I try to reboot to system, TWRP is saying 'No OS Installed!' So, I'm wondering if the .img is not really being installed? The install of the .img file happens almost instantly.. maybe it's not really installing?
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
Please, go to twrp and format data , reboot device again into recovery, wipe all from advanced wipe apart External Storage , right now you can install and use LOS 15.1 & Gapps like it should ... following the installation instructions in the OP !

What you did right now on your device it's a huge mess and require a hard clean in order to be all properly installed !
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] qlue4e:
bro which twrp are you using and have you flashed the lineage os zip :)

after you have flashed the os zip flash the boot.img( if you device is the wifi only model ) and see if its booting normally. after that try to flash the gapps.

its better to do it from the beginning sometimes you miss somethings.

BT enabled on LOS 15.1 !

Hi!

Right now I just managed to fix Bluetooth on LOS 15.1 Oreo 8.1 !

Yes, it's not 100% correctly working as there is some interference with wifi - but those BT issues will be fixed when I'll update wifi kernel drivers to Oreo from Mate 8 !

As I think you already guess, BT was fixed by updating kernel BT drivers to Oreo from Oreo Mate 8 kernel source code !

The next update will be here in a few days even if the security patch will not yet be updated to May 2020.

I already checked Magisk and unfortunately after installing it, gatekeeper stop working properly ... and because FPS is closely related to gatekeeper , the fingerprint scanner stop working as well, that's why you can't even set a Pattern to secure your device ! I already tried to conntact [MENTION=4470081]topjohnwu[/MENTION] to find a workaround, but unfortunately he did not answer me.

In conclusion, the full ROM is not compatible with Magisk, but I'll try to add a second version without FPS enabled in order to be used along with Magisk !

The only one that can help you to run full ROM LOS 15.1 with Magisk is [MENTION=4470081]topjohnwu[/MENTION], as I have no clue why gatekeeper stop working !

Unfortunately there is also a bad news - my tablet was lost by provider ( I guess it'll take a few good months until they refund my money - to be able to order another one) !

As [MENTION=7442736]Incomtus[/MENTION] need his tablet back, starting with Sunday, May 17, 2020 - the whole development here will be suspended ( kernel updated to 4.4 also will be suspended as I need a device to test my update kernel from time to time ) .

Thank you very much for your attention !

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

I didn't test well the LOS version with BT enabled, and now I notice that I can't connect my device to the 2.4GHz WiFi network, but I can only connect to the 5GHz one. I'll try to fix this new issue before to release a new update.

[MENTION=10727441]ödicar[/MENTION] he send me today his device to be able to continue the work on MediaPad M3 8.4, as without a device all the work here will be suspended ! Thank you very much [MENTION=10727441]ödicar[/MENTION] and to you [MENTION=7442736]Incomtus[/MENTION] because you lend me your devices !

So, as soon as I'll receive the new device from [MENTION=10727441]ödicar[/MENTION], I'll release a new update and I hope that by then the LOS Team will include also the new security patch for May 2020 on LOS 15.1 !

i am using huawei dtab d01j, it was converted to huawei mediapad m3. I couldn't rotate the screen when in emui 4.0 (Android 6), emui 5.0 (Android 7) .When I used Android 7 emui 5 ,I couldn't use the front camera.

I'm sorry, I don't think I was clear enough!

The tablet I own now is not mine, and I have to return it Sunday 17 to [MENTION=7442736]Incomtus[/MENTION] !

Yesterday [MENTION=10727441]ödicar[/MENTION] sent me (borrowed me) his tablet from Germany via DHL, so I could continue the work started here.

Anyway, thank you very much for your help ... at the moment I don't need it, but if it'll be needed in the future, I'll contact you for sure :o

Please, can you converted back to DTAB D01J ? In fact your device it's BTV-L0J the MediaPad M3 Japanese version and my ROM should work on this device as well.

If you'll have some issues after converting the tablet back to the Japanese version and installing LOS 15.1, then I guess I can help you ... but now, as you have camera issue also on stock EMUI, there is no chance to fix it .

I'll make a comparison of the kernel on the tablet (BTV-L0J) with the kernel on the model BTV-DL09 / W09 and I'll keep you updated if indeed LOS 15.1 will work safely on the Japanese model.

EDIT:

I have already checked the kernel especially the camera drivers and they match 100% and also defconfig match ... so there is no reason why LOS 15.1 cannot run on the MediaPad M3 the Japanese BTV-L0J model! It should work properly because all three devices (BTV-W09, BTV-DL09 and BTV-L0J) share the same kernel.

Please, can tou send me your model by running this command on your device ?

Thanks !

Thank you for your answer about my SIM issue. I have installed and enjoyed this ROM (LOS 15.1) for 5 hours.

I figured out some issues as follow:

1. The SIM works well with LTE network and SMS but the CALL funtion does not work. (The stock BTV-L0J ROM also has this problem)

2. The rotation sensor seem not work.

Do you have any solution for these issues?

P/s: Cast funtion works well with android tv
