Okay, managed to get Nougat and root for my BTV-DL09. Here is a fast forward tutorial how to do that.
I could only root it by using Magisk, Supersu (even the special emui5 ones) did not work for me.

Files:

ROM: http://update.hicloud.com:8180/TDS/data/files/p3/s15/G1224/g490/v78425/f1/full/update.zip (BTV-DL09C233B336)
Data: http://update.hicloud.com:8180/TDS/...full/dualcu/cn/update_data_full_dualcu_cn.zip
TWRP, make sure to use twrp_BTV-DL09_5_greatslon.img : https://androidfilehost.com/?fid=817550096634750327 (thanks to greatslon)
Root: https://forum.xda-developers.com/apps/magisk/official-magisk-v7-universal-systemless-t3473445

I came from version BTV-DL09C100B006, this is how I did it:

Bootloader must be unlocked, custom recovery installed (Do not install the one for EMUI5 yet, it won't boot).
Enter recovery by adb reboot recovery
Wipe, reboot recovery
Flash ROM + Data
Flash Magisk Root
Flash Recovery again (will be overwritten by the udate)

Reboot, Done.

Download playstore / vending APK from APKmirror: http://www.apkmirror.com/apk/google-inc/google-play-store/google-play-store-7-6-08-release/ and transfer it on the device.

There is an app called "Downloads" preinstalled (there is pretty much nothing on the tablet, not even a browser after flashing it), you can use that to open/install the play store APK and get things going.

Please make sure you know what you are doing and you know how to recover from a soft brick. I take no responsibility if anything goes wrong.

The version you should have now is BTV-DL09C233B336 with security update from February included.

Beware that:
1) this is a chinese ROM
2) Nougat version 7.0.0 :(
3) if you don't like the downgrade process is difficult
4) if you want to downgrade have to find another ROM!!!

any idea to downgrade please
You need another ROM, FULL not OTA.
1) extract from the .APP the recovery (both) and boot images
https://forum.xda-developers.com/showthread.php?t=2433454
2) get a build.prop from the ROM you want to install
3) copy the build.prop in the /system folder, overwriting the original: now the old ROM will unlikely boot!
4) go in fastboot mode and flash recovery, recovery2 and boot images
5) copy the update.app in the dload folder
6) reboot and maintain pressed both volume keys to start recovery
7) if you are lucky the recovery will install the ROM.

Of course you will loose all your data (uhm, not even but... MAKE A BACKUP before!)

If you don't know well how to do ALL this don't even try!

If you have the original european LTE ROM please share it!!!

What are you saying about???
It depends from which ROM have you installed!

Often the truly incompetent Huawei developers uses the wrong keys...

Hi nicolap8 even I followed the same steps as you suggested with the file links you shared and I am also NRD90M test-keys on my Mediapad BTV-DL09
installing Magisk first time gave me a fail message but second time it works like a charm. thanks
could you help, thanks

Switched to eu rom, updated to nougat.. unlocked bootloader and rooted with magisk
But using magisk caused the fingerprint sensor not to work at all and there is no settings for the FP in the settings menu.
Uninstalled magisk and the fingerprint worked again but obviously I lost root.
Flashing SuperSU didn't work gives an error in twrp no matter what version I try.

Any idea on how to root without compromising the fingerprint sensor?? :/

Fingerprint Button

Hello, velocity.

Worked for me, thx.

The fingerprint button doesn't work anymore.

Is there a way to activate it (without loosing root by uninstalling magisk)?

Kind regards
