It's nice to finally see a thread dedicated specifically to our model. I didn't get my unlock code yet,I will try your live chat support in a bit. I created an unencrypted boot file for our device but I cannot test it yet. If someone wants to give it a go here it is boot-unencrypted.img(flash it using fastboot)

You're welcome!
Flashed but got a bootloop after the animated splash screen.

I see, I will try again after i unlock my device as well. Since the boot file is encrypted you should point out that for now only magisk systemless root works

I'm trying to compile kernel sources but can't get the device to boot.

What I did:
-Splitted the stock boot.img with https://forum.xda-developers.com/showthread.php?t=2319018

boot_info says:

Code:

$ ./boot_info boot.img 
PAGE SIZE: 2048
BASE ADDRESS: 0x80000000
RAMDISK ADDRESS: 0x81000000
CMDLINE: 'androidboot.hardware=qcom msm_rtb.filter=0x237 ehci-hcd.park=3 androidboot.bootdevice=7824900.sdhci lpm_levels.sleep_disabled=1 earlyprintk slub_min_objects=12'

So I repacked the stock boot.img with:

Code:

./mkbootimg --kernel boot/boot.img-kernel --ramdisk boot/boot.img-ramdisk.cpio.gz --cmdline 'androidboot.hardware=qcom msm_rtb.filter=0x237 ehci-hcd.park=3 androidboot.bootdevice=7824900.sdhci lpm_levels.sleep_disabled=1 earlyprintk slub_min_objects=12' --base 0x80000000 --pagesize 2048 --ramdiskaddr 0x81000000 -o out_boot.img

Flashed with fastboot and works fine.

Then I compiled kernel sources with:
(GCC downloaded from https://android.googlesource.com/platform/prebuilts/gcc/linux-x86/aarch64/aarch64-linux-android-4.9/)

Code:

$ export ARCH=arm64
$ export CROSS_COMPILE=aarch64-linux-android-
$ export PATH=$PATH:/path/to/aarch64-linux-android-4.9/bin
$ make merge_msm8937_64_defconfig
$ make Image.gz-dtb

Then I replaced boot/boot.img-kernel with Image.gz-dtb, repacked, flashed out_boot.img but device does not boot.

Unfortunately we can't get the /proc/config.gz because Huawei disabled it.

You are probably right.That's actually a bit disappointing..

Solved! Just use SuperRs Kitchen to extract and repack boot.img

can you test if it's possible to make an unencrypted boot?

What do you mean with unencrypted?
This is what's possible to handle with the kitchen:

Add/Remove init.d support
Insecure/Secure the boot.img
Remove dm-verity
Add/Remove forceencrypt

This is what's possible to handle with the kitchen:

After extracting the boot file you can edit the fstab file and get rid of file encryption. To do that go to the folder ramdisk and open the file "fstab.QCOM" (use a text editor).
Look for the line:
/ dev / block / bootdevice / by-name / userdata / data f2fs nosuid, nodev, noatime, discard, inline_data, inline_xattr wait, check, fileencryption

Delete the ", fileencryption" part ,save and then repack the modified boot.img
It should work after flashing it

awesomeness!

So glad there's a proper page for my tab now and bonus it's full of clear and useful info, anyone found a way to root this thing properly yet (anyone tested the Magisk?) All I need to do is root so I can get rid of the bloat to free up space internally

djclark25 · Jan 23, 2018

Success!!!!! After not receiving my unlock code I phoned them, rather than using the live chat. The operator had all my details and said "The codes here, for some reason it just hasnt been emailed to you......"

So I now have root on my AGS-W09 using the following steps

Enabled USB debugging and OEM unlock in Developer Options
Rebooted into fastboot and unlocked bootloader
Used fastboot to install TWRP
Rebooted into recovery (Is in Russian, have to set to English each time)
Flashed Magisk V14 (V13.2 and V15 gave errors)
Rebooted, installed Magisk Manager and Titanium backup.
Launched Titanium Backup and was prompted for root which I granted

JOB DONE!!!!!

Maybe we will get custom rom in the future?

Zillinda · Jan 25, 2018

Does this work for AGS-L09 or only for AGS-W09?
EDIT: Tried it, this TWRP also works on AGS-L09!

KokkoM · Jan 25, 2018

Yes, rooted! Tomorrow i test if Magisk update via app work. I have earlier same problem with Nvidia device (only v14 flash work) but it updated via app v15.3 and works fine

So, after two days messing i got it installed

It wont update with app.
I test also other things so i installed this twrp, just becouse is english for default: https://drive.google.com/file/d/1pInrsaP_DHWUJVgTne_N-JbYFKLcz1Fn/view (from: http://4pda.ru/forum/index.php?showtopic=828565)

For Magisk 15.3 go twrp and format data, factory reset after that dont reboot, go back and flash 15.3 zip.
After reboot just install latest Magisk manager.
