I did not yet encountered this issue on my BTV-DL09, but I charge always on low mode ( connected to PC via USB - for development reason ) and also I set up a fingerprint to unlock my device ! So , indeed are not at all the same condition.

The last thing that you can try it's to put your device into fastboot mode in order to flash my TWRP 3.3.1-0 ! While the device it's power off , just connect USB cable and at the same time press and keep pressing volume down key - your device should open quickly into fastboot mode.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] CarloHD:
Already tried, there is nothing, neither fastboot nor erecovery, nothing. I think that somehow with the restore of the NAND, the table of the partitions has been deleted,

Flash it successfully but sensors not working i have d-01j converted to btv-dl09

and i have weird problem in the browser get this error when trying open site even google.com

this site cant be reached
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] sergio_sant:
I just flashed the latest build on my BTV-W09. Everything I use works well so far, I'm so happy with this rom. The only thing I miss is the fingerprint scanner gestures for navigation, as I don't like having the navbar always there.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
Thanks, I'll check what drivers for sensors use D-01J model, maybe there is a way to fix it !

I'll not spend my time to implement fingerprint scanner gestures for navigation as LOS do not provide such feature !

Anyway, on Android 10 there is a choice to disable navbar and use Gesture navigation, this is another reason why we do not need fingerprint scanner gestures.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] 0m M0m0d:
Yups, I think so too, I also experienced the same thing a few days ago. after formatting the data and restore backup, then somehow my tab is experiencing hard brick, no power, no recovery, no fastboot.

the only way to overcome this is by the test point method, using board software.

but be careful with this method, because it can result in the loss of IMEI, SN, and possibly also network lock.

if you have the skills, then just flash recovery, erecovery, and fastboot just with this method, after that do the flash through normal fastboot / recovery / twrp. no need to flash all the files in the board software , because it can lead to things that I have explained.

Flash all boards software only for the last alternative.

---------- Post added at 07:26 PM ---------- Previous post was at 07:11 PM ----------

if you want the sensor to work, then use the original firmware d01j before switching to LOS 15.

Or, if you are using Firmware DL09, then you must first fix the sensor in this firmware before you switch to LOS 15. If not, then your sensor will still not work. as is known that the sensor problem is an issue in d01j rebrand to dl09.

---------- Post added at 07:31 PM ---------- Previous post was at 07:26 PM ----------

I think the driver is the same as DL09, but the difference is sensorhub.img software.

because I have d01j rebrand to dl09 with the sensor working normally.

I managed to make Andriod 6 working by flash boot.img and sensorhub.img from original firmware but not 7 because I don't have original firmware for android 7 if you can make a TWRP backup from your device it will be much appreciated
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] friedsonjm:
If you want, I can make a current backup, do a factory reset, do a TWRP backup, post that backup where you can get at it, then restore the full backup to my tablet. Will that work?

Hi !

I finally arrived with the kernel update at Android Kernel Linux 4.3.0 with a delay of 3 weeks, due to several patches that should not have been added, because all them was reverted later and I didn't know at the time I updated the kernel !

It will take at least 2 months to update the kernel from 4.3.0 to 4.4.0 and another few months until will be 100% compatible Android Oreo/Pie !
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] friedsonjm:

[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] 0m M0m0d:
Sorry for late reply.

I am a little less understanding with what you mean.

What twrp backup do you want? d01j or dl09?

and what backup file do you need?
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] tek3195:
If you have 6 partially working it may be best to complete setup for six then let it do its own version update via OTA. By doing it that way you can put off upgrade to overnight once it is downloaded. Then you can go to HWOUC folder in internal storage and copy(don't cut, just copy) it to somewhere safe. After copying you will then have full firmware for android 7 for any later use if needed. After OTA installs it erases content of HWOUC and will delete your saved copy if left internal. I save my to external_sd and rename the folder just to be safe. Safest of course would be to store on PC.

That was for W09. Correct path to BTV-DL0j ota files is a couple posts down..

Hi

I want a backup of d01j

I manage to get android 7 boot.img backup but I didn't find sensorhub.img for d01j I only have android 6 version
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] almahdi:
I cant upgrade to android 7 via ota i don't receive any update I don't why
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] tek3195:
Have you tried Hisuite in Windows to update ? I have posted link to board software that you should be able to get sensorhub.img from. There are files for W09, DL09 and Dl0j inside

http://www.mediafire.com/folder/43cwcl8hih2u2/BTV-DL09
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] 0m M0m0d:
There is no HWOUC foder on the d01j firmware.

The OTA file in d01j is located under the data, which cannot be accessed through the file manager, but can be accessed via twrp.

on android 6 d01j, the ota file is located at data / fotapkg.

and on Android 7 it is located in the data / update / fotapkg

full backup is around 7.5gb, I don't think I can upload that much.

and for your information, there is no sensorhub.img file in the backup.

and if you want try to flash sensorhub.img directly, then that won't work.

That's because you didn't return back the d01j oeminfo.

After you rollback to Android 6, you must restore the d01j oemInfo. do it after you are on anroid 6, not before.

After that, re-flash the 5 img (boot,system,cust,userdata,recovery) of android 6 files again.

if you do according to my instructions, then you will be able to update to Android 7 without any problems.

I have made a correct rollback tutorial video on YouTube,

and of course also the d01j rebrand sensor fix tutorial.

I will publish the video soon, as now is in the process of editing.

remove your sim card, just use wifi only.
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] almahdi:
I don't have sim card on device
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] 0m M0m0d:
Check your IMEI and your network status.

It may be that your IMEI has been deleted and your network has been blocked when you repair your device via DC Unlocker and HCU.

To check the network status, try to enter your sim card, does your sim card get a network ???

Another thing, there might also be a problem with your SIM tray slot, so your device always detect a sim card in your device.

Because the notification that you show is because of the sim card in the device.

help, got this error

E3004 this package is for device: hi3650,btv; this device is .

my tablet is BTV-L0J

EDIT turns out i used old twrp. theres an old guide in this forum :(

but the new twrp

twrp-3.3.1-0.img md5: 984779bc7af812eb1b3e67e197732dbc

cannot be downloaded NO MIRROR FOUND

EDIT

been trying to download the twrp for 1 hour now. Still no mirror found.

EDIT: finally able to download, but after flashing twrp thru fastboot, then doing fastboot reboot, im stuck on yellow text screen "your device has been unlocked blah blah" and on the bottom "your device is booting now...".

if i try to press VOL UP and power, it reboots and goes to eRecovery.

when i was using the incorrect TWRP from the out of date guide, i can go into recovery.

EDIT:

just keep reflashing TWRP and itll work.

so now im on LOS, and everything seems good but I can't use auto rotation. The accelerator seems broken. I'm also missing IMEI. anyone have any solution?

Edit

Rotation works. It take a few secs to rotate.

IMEI missing, Baseband unknown. Even with sim card plugged in.

Someone saying ROTATION not working a few pages back? I found a fix

1. Restore your TWRP backup for "Cust" and "Vendor" using TWRP 3.1 by urdu_petru on page 1.

2. Reboot, your phone will stuck on yellow text screen

3. Boot to TWRP 3.1

4. Install LineageOS zip file

5. reboot and sensors are working again. Rotation will work (1-2 seconds delay).

now i just need to find a way to

1. Fix Baseband Unknown

2. Fix 5 GHz wifi

[MENTION=2335078]surdu_petru[/MENTION]

Can you add a huge warning for people to not follow this guide?

https://xdaforums.com/mediapad-m3/how-to/guide-t4085995

following that guide results in Baseband Unknown and TWRP backup that cannot be restored (it can be restored but will stuck on yellow text screen). Probably because it links to out of date TWRP that have issues with "Data" partition among other things.

EDIT: anyone with docomo Mediapad M3 BTV-L0J and want lineageos, DO NOT convert to BTV-DL09.

1. rotation will be broken in Lineageos (can be fixed, see my previous edit)

2. 5GHz wifi will be gone in Lineageos

3. Dark theme and accent will be partially broken in LineageOS
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] surdu_petru:
Ok, but the guide do not affect all devices, right ?
[Huawei Mediapad M3 ROMs, Kernels, Recoveries, & Ot] orangpelupa:
theoretically it should affect all device as it tells people to use an out of date TWRP, and your lineageos cannot be flashed using that out of date twrp due to that twrp have issue with data partition (it cant even wipe "data" after typing "yes")

EDIT: Bug report

1. Gyro and Accelerometers got around 1s lag. (Could be inherent bug, as it was also laggy with stock docomo firmware.)

2. Gyro cannot stay still even if you lay the tablet on a floor. Gyro sensor will still twitch around. Can be easily observed with https://play.google.com/store/apps/details?id=com.blogspot.novalabsandroid.gyroscopetest&hl=en. As for the values, any app that shows gyro value will work, showing the gyro twitching.

What web pages do you test? Nowadays most pages use https. Can you try http only pages like http://neverssl.com ?

What's your gyro test result? If you use CPU-Z, go to sensors tab, does the GYRO values stays at 0,0,0 when you lay the tablet on a desk? In my case it was 0,0,0 on stock docomo, but jumping around in LineageOS. After i converted my docomo to EU and flash lineageos again, its still jumping around.

The new kernel 4.4.0 it's coming soon !

Hi !

I was able to successfully update the kernel from stock 4.1.18 to 4.4.0 without to break anything !

Currently the kernel is on 4.3.0 but there are very few patches ( I think around 1000 new patches need to be added to the over 14,000 already added ) left to add up to 4.4.0, so I allowed myself to do a simulation for 4.4.0 to see if our device really boots with this new version !

I hope that in a week we will have here the new update with the new security patch for August and with the new kernel 4.4.0.

Later the kernel must be updated to 4.4.227, which is the latest version today :)
