I am surprised. Why I have already followed the installation instructions. But when I reboot. It can't boot to LinagesOS 15.1. It always stay in the boot animation. I waited a long time. But it stilly stay in the boot animation.

My devices is BTV-W09

How can I fix it???:oops::oops::oops::oops::oops::oops:

(I have a bad English)
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
Maybe flash boot.img for WiFi only devices ?
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] Cmgdels:
I flashed boot.img.

I fixed this question by myself.:) I found and flashed the boot.img you sent earlier. then it's boot to Los15.1. Maybe there are some question in your boot.img now. if there are, Can you try to fix your boot.img?

(I have a bad English)

Hi there i have this tab which was hardly bricked. Now i got it fixed from a shop but he only found japanese firmware emui 4 and android 6 . I can't even update it. Because it asks me to put docomo sim. Is it possible to install lineage os 15 on android 6
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
At the bottom in the OP you will find this require :

ROM Firmware Required
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
it seems that you have a Japanese device, this problem has been discussed here before, if you read the older posts you will surely find a solution to the problem
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] ryvandy:
Hello, i recently install this ROM on my BTV-L0J, i thing i noticed the charging speed is so slow ? is it common thing in this ROM ? Thank you...

edit, from 40% to 100% it needs about 3 - 4 hrs, using 'Ampere' app it only show measure charging 400-500 mAh, while other normal huawei tab with the same charger measured around 2.300-2.980 mAh (2h 40min from 20 to 100%)
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] Grander77:
Hello,

I have a BTV-W09 and have so far had no problems with Los 17.1.

But now I want to go back to Los 15.1, I also followed the instruction exactly, but after the restart after the installation, only the circles of the start animation appear. After 10 minutes I always broke off and played everything again, the same result.

Everything is correct, I installed the 'old' TWRP 3.3.1.0, format data, factory reset, clear vendor + system, install los15, flash boot for W09.

Where could be the problem?
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
I can try to look into logcat if your device will start it ... you can try to do this command on your PC while your device start booting into LOS 15.1 ( USB cable must be attached)

adb logcat > log.txt
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] ZhFuwe:
Hello,

I also have a BTV-W09 and had meet the same problem. I didn't install Los 17.1. I upgrated it from EMUI 5 ,Android 7 . Everything is correct, but only startup animation appeared.

It seems that I can't use adb to catch the log unless it start successfully.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] Cuonglla117:
Hi Petru, first i want to thank for all your hard works. But im still wonder that why selinux enforcing and device encryption still doesnt work on this rom? can you explain me why ... thanks
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
because they were not fixed, obviously they doesn't work !
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] sunbingms:
Same device, same problem here. I fixed it by using TWRP to [wipe cache]. The charging current increased from 500mA to about 1200mA
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] CarloHD:
I was finally able to boot TWRP 3.3.1-0 (downloaded from the second post in this thread) and following the steps I flashed LOS15.1, but after flashing the rom and doing the reboot, the device won't turn on, it stays in the "your device is booting now..." screen for quite a few seconds and then reboots, again retry to boot, reboot, and then it goes into eRecovery with "download last version...", "reboot", shutdown" buttons...

I can boot again in recovery and I tried redoing the format data, with the same result.

I really hating this device...
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
if your device it's BTV-DL09, I'll prepar a new boot.img for you in order to send me some info from your device ( to be able to check why it's not boot on LOS 15.1 )
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] CarloHD:
Yes, it's BTV-DL09

i have roll back to official firmware, for now i have the bootloader locked, so the system is clean.

i take the buildprop that i attach here.

however... i prefer to install LOS20, but until i can't boot any rom i think is better to start with LOS15.1, do you agree?
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
You have the same device like me : BTV-DL09 with EMUI 5.x C100B311 - I really don't understand why LOS 15.1 it's not working ... and the installation of LOS 15.1 it's very very easy to do , once you formated data in twrp , just install LOS 15.1 and it should boot fine !

Anyway, please flash this boot.img in your device : fastboot flash boot boot.img ( after LOS 15.1 was installed )

After flashed boot.img try to see if device boot to LOS 15.1, if still not boot , go to TWRP and perform those operations :

You need to create a tmp folder previously !

Please send me this file : logcat-normal.txt

Thanks !

EDIT : The Bootloader must be unlocked ! maybe you didn't mean locked earlier, right ?
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] CarloHD:
Yes i know it must be unlocked, but after restore the official firmware it has been locked again. It's a normal behaviour, right?!

Anyway i've unlock the bootloader, follow the steps on the first message to flash recovery and LOS 15.1, i've tried to boot, without success. Flash the boot.img that you sent, again I tried to boot, but no success.

i've run the command from adb shell but give me an error

adb shell
# mount -t ext4 /dev/block/bootdevice/by-name/splash2 /splash2

[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
ok, did you type those command on TWRP ?

If YES, please , can you see splash2 afer you run this command ? ( ofc in TWRP )

EDIT: if you are able to see /splash2 , please create splash2 before mount :
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
ok, good !
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] CarloHD:
after reboot it stuck on "your device is booting now..." for some seconds, then reboot again to the same screen, then on the eRecovery, same behaviour as before

i have again boot on twrp and run those commands

mkdir splash2
mount -t ext4 /dev/block/bootdevice/by-name/splash2 /splash2
exit
adb pull /splash2/logcat-normal.txt tmp/
adb: error: failed to stat remote object '/splash2/logcat-normal.txt': No such file or directory

what's inside splash2 folder after mkdir and mount

[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
Yes, thanks ... I see it, it should be this file in splash2 "logcat-normal.txt" - but it seems that LOS 15.1 is not even installed on your tablet

Can you make a screenshot when LOS 15.1 finished to be installed in TWRP ?

EDIT:

Or you can take a video recording while you try to install LOS 15.1 on your device : starting with format data, reboot device from twrp in twrp to be able to use data, install LOS 15.1 and reboot ! Thanks ( You can send the video via Private Message )
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] CarloHD:
here you go. format data, reboot recovery, factory reset, wipe system + vendor, flash LOS15.1, nothing else.

[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
I haven't encountered this problem yet, but it's definitely due to the old wifi drivers ... you have to wait a little longer until the wifi drivers will be updated to Android Oreo !

The kernel it's currently only 5% updated to Oreo by adding almost 4000 new commits ... so we can't expect that this ROM to working very well at this time :)

EDIT:

It seems that you can't download the attachments after installing Gapps, without it I managed to download any kind of attachment !

At the moment I have not found a solution to this problem.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
New Update of LOS 15.1 !

Hi !

There is a new BETA update of LOS 15.1 for our device BEETHOVEN into OP !

Changelog :

- update security patch level to : May 5, 2020

- Bluetooth fixed

Wraning : there are interferences that lead to repeated interruption of the bluetooth connection if you use bluetooth and wifi simultaneously, this issue may be fixed after wifi kernel driver will be updated to Oreo

EDIT:

I'll provide soon the new boot.img for WiFi only devices and also a new build without "gatekeeper" enabled in order to be able to be root with Magisk Done !
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] friedsonjm:
If we are using the previous version of the ROM, do we need to do a full wipe, or can we just install this version over it?

Also, FPS vs non-FPS version - what does FPS stand for? Frames-Per-Second?

thanks, jf
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] davidmoore:
Finger Print Scanner, I believe.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
Full wipe needed only first time so for update ROM it's not required !

Also the attachments download issue wasn't yet fixed ... it's working well but only without GApps installed :confused:

I'll look for a solution in the near future, thanks !
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] friedsonjm:
Hmmm... getting stuck on 'device has been unlocked' etc. screen and won't boot. I'll do a full wipe and try a reinstall - fps version.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
Full wipe not required ... just do a Swipe to Factory Reset on TWRP and will be enough.

Also dirty flash must be included at least wipe cache & dalvik after the ROM was updated via TWRP !
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] friedsonjm:
Even with full wipe, getting stuck on the boot screen. .. 'Your device is booting now.' Eventually reboots into the EMUI eRecovery screen. I'm using the FPS version of today's ROM, and full GAPPS. I'm going to try again with no GAPPS.

NEVER MIND. I'm dumber than a rock today... forgot to flash the .img file...
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] qlue4e:
dont forget to wipe cache & dalvik like surdu pointed out and if you use the wifi version dont forget the boot.img the one surdu provided after flashing maybe you can format data
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
Using Full GApps it's not recommended at all !
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] friedsonjm:
Up and operational, fingerprint sensor works great. Looking forward to working downloads. Thanks so much for your patience and continuing effort on this!
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
Does you tested bluetooth ? it's working on your device ? Thanks !
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] friedsonjm:
Well, I can turn the bluetooth switch 'on' in the Connected Devices screen, but after a quick flash of blue, it turns grey again, then I 'open' it to full-screen Bluetooth, I can toggle it to 'on,' but it stays grey. Using my PC, searching for Bluetooth devices, it never shows up. Going back to the Connected Devices screen, Bluetooth shows as 'off' again. So, no, can't get Bluetooth working.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
Try to restart your device and check again ...

EDIT :

After I connected my device to BT there was no sound, just restart my tablet an all seems to working well now !
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] friedsonjm:
I've rebooted, no change.

---------- Post added at 01:15 PM ---------- Previous post was at 01:13 PM ----------

I've completely powered down, booted, still BT does not work. Must say - this is the fastest I've ever seen Lineage boot!
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
Please, can you send me a logcat when you try to enable bluetooth ?

Just connect usb cable, and type :

in the meantime try to activate bluetooth while this command running ... after 30 seconds you can disconnect the usb cable and send me this file ( log.txt ) via PM. Thanks !
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] friedsonjm:
PM sent.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
Thanks !

I'll look for a solution in the near future, it seems that the problems are on the same line, BTV-L09 (LTE & WiFi) vs BTV-W09 ( WiFi only ) ... so I guess that BT currently only works on LTE models !
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] hellouu:
unfortenately i still cant play the 60fps video on youtube even with the lastest rom...

youtu.be/9jZ01i92JI8

this is the video that i tried
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
Yes, I know ...
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] friedsonjm:
I note that only the Wifi version requires the use of a boot image - any possibility the issue could be related to that?
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
Indeed, it is also what I guess

Edit:

There is a little difference also on Bluetooth part as we can see now.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
Test BT on BTV-W09 !

Hi !

There is a test version for Bluetooth, only for BTV-W09 devices :

LineageOS-15.1-BEETHOVEN_2020-05-25.zip

Please, this time do not install any additional boot.img, flash only this new ROM on TWRP and perform a factory reset before .

Please let me know if BT it's working with this new build, thanks !

I'll provide tomorrow another build if BT still not working .
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] qlue4e:
Have anyone tested the bluetooth version for w09 so far, im busy with the university and using my tablet for word and other stuff. If anyone free could test it and inform surdu it would be very helpfull, surdu makes already the most hard part that we would have not being able to do,:) Again thank you for your hard work.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
No problem, if no one will test, then I will assume that BT works on all devices and any future request related to this topic will be denied !
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] friedsonjm:
Heck, you know I'm going to test! :)

---------- Post added at 02:49 PM ---------- Previous post was at 02:32 PM ----------

Installed and booting now... taking a very long time to boot (Linage line and circle moving) but that is not unusual with first boot on Lineage. I'll let it run another 15 minutes or so...

---------- Post added at 03:03 PM ---------- Previous post was at 02:49 PM ----------

...and we are still stuck on boot I'm going to back into Recovery, do a complete wipe, and install ROM and GAPPS from scratch. I'll use PICO Gapps.

---------- Post added at 03:24 PM ---------- Previous post was at 03:03 PM ----------

BLUETOOTH - with the new ROM, Bluetooth can be turned 'On' and it says it is discoverable with device "BTV-W09" However, it can't see any of my other devices - Surface Pro, other tablets, Pixel 2XL - and they can't see the the Galaxy Tab either. As far as I can tell, it is not actually broadcasting BT. Also, I could not get it to recognize a fingerprint, although the option did show, it never got a reading from the sensor. Last FPS version before this, the sensor worked fine.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] qlue4e:
oh thank you very much bro :good:

did you perform a factory reset and wipe dalvik cache and cache after flashing the rom
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] friedsonjm:
Actually, because it got stuck after installing Gapps, I did not. Will install ROM now and wipe both and reboot.

---------- Post added at 04:47 PM ---------- Previous post was at 04:31 PM ----------

....and once again, is stuck on boot. I'll wipe everything and try again.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
Ok, I understand that it's still not working . Thanks !

I'll uplaod a new test BT ROM in a few days with FPS working.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] friedsonjm:
Complete wipe and reinstall - no change, Bluetooth switch turns 'on' now, but Tablet can't see or be seen in BT.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] mossief1965:
My install fails - "updater process ended with error 7 error installing zip file XXXX failed to mount /3rd modem (invalid argument) ...done"
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] friedsonjm:
I had the same problem until I installed the correct version of TWRP. Check the OP.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] mossief1965:
Thanks. Managed to install but now I get a message about encryption failing and won't go past that
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] friedsonjm:
1. Per the OP, encryption is not enabled, so I don't know why you would get that message.

2. What version of the tablet do you have?

3. I have had the best success in installing this by wiping everything except internal storage before installing it.

jf
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] mossief1965:
I've BTV-W09. Everything installs ok but I get this message on first boot. Don't have the tablet to hand so can't give the exact message now.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] friedsonjm:
Are you using the latest version of the ROM, the one that does not need the separate boot file? What did you wipe before installing? Did the message stop you from using the tablet?
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] mossief1965:
Thanks, I'm out at the moment so can't check the details but I know I've the version that needed the boot image. I wiped all that was mentioned in the OP. Yes I cannot go past the error message it just reboots.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] friedsonjm:
OK, I suggest you download the latest version (no boot image), wipe everything but internal storage and SD Card (if any), install new version and report back.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
First, you wasn't able to read installation instructions, where it's state clearly what version of TWRP you need.

Second, you are in the same first stage, you're not able to follow step by step installation instructions, that's why you have encryption message.

That's the point, you shouldn't wipe all what was mentioned in the OP, instead you need to follow and properly perform all steps (one by one ) from OP - Installation Instructions !

New BT Test Version For BTV-W09 !

New Test version ( for Bluetooth ) of LOS 15.1 only for BTV-W09 ( WiFi only ) devices !

Downloads : LineageOS-15.1-BEETHOVEN_2020-05-31.zip

This update does not require installation the specifically boot.img for BTV-W09 ( it's already included by default in this ROM )

Please report back if BT it's working ( only for those who had problems with BT on previous versions ) , Thanks !
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] friedsonjm:
BT turns on and pairs! However, can't receive a file transfer because of the problem downloading files from BT, email etc.

thanks, jf
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
Ok, can you use bluetooth headphones to listen to music ? Thanks !
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] friedsonjm:
Sadly... I don't have BT headphones...
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
Do you have the same issue when you try to receive a file ?
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] friedsonjm:
Yes... can't get one downloaded from email or via BT, same error.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
Ok, I'll check this issue soon ... but at least you should be able to send a file to another device via BT. Did you checked this to see if it's working ? On my device it's working ... I can send any file via BT to other devices and also bluetooth headphones works well.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] friedsonjm:
I retested today - I was able to both send and receive via BT, thanks!
