Sure, it is based on @kev1807 's post on this thread https://xdaforums.com/mediapad-m5/how-to/how-to-downgrade-firmware-t3856385

Couple of notes though :

1. My SHT-W09 is Japan/Asia version? (I forgot the "C-number")
2. I have .173 version which is not compatible with the dc-unlocker (I checked and it didn't work)
3. Downgrade using 8.0.0.163(C432) firmware
4. Still written as .17 version, however the layout is changed
5. Dc-unlocker now works flawlessly

Guys am thinking of moving this tablet on. What's the best method to remove the warning at the start of the tablet? Am assuming I will need to relock the bootloader?

I was able to unlock the bootloader on my CMR-W09 (firmware 181 or 183, don't remember) and root my pad.

In order to unlock your bootloader with DC-unlocker you need to downgrade first to firmware version 168 or lower.

It goes like this:
(Replace ? with . in URLs)

1. Downgrade to firmware 168 using an image from androidhost?ru
androidhost?ru/97T for CMR-W09

If you have a different model, these are the images from the same place that appear to work. Use the search. (credit to Pianoralf on android-hilfe.de)
M5 10.8 WIFI: Huawei MadiaPad M5 Cameron-W09A 8.0.0.168 (C432) MagentaCLOUD
M5 pro 10.8 LTE : HUAWEI MADIAPAD M5 CMRCAMERON-AL19B 8.0.0.161(C432) Link ( RU)
M5 8.4 WIFI: MEDIAPAD M5 8.4 SHT-W09 SCHUBERT-W09A 8.0.0.163(C432) Link (RU)
M5 8.4 LTE: SHT-AL09 8.0.0.163(C432) Link ( RU)
M5 10.8 LTE: CMR-AL09 M5 CMR CAMERON-AL09A 8.0.0.161(C432)

Open the archive and extract the dload directory to your SD-card. Then turn off device and reboot into update mode (power+volup+voldown pressed). It should then downgrade.

2. Bootloader unlock using DC-Unlocker to get unlock code (4 € credit required) and Multitool to apply said code.
3. Congratualtions, your bootloader is now unlocked.
4. Update to current version as needed.
5. Use Magisk Manager to create modified bootloader. Flash modified bootloader to gain root. This should be described elsewhere here in the forum. I did it using this guide (in German) where you will also find already modified images for CMR-W09:
www?android-hilfe?de/forum/root-custom-roms-modding-fuer-das-huawei-mediapad-m5-10-8.3359/der-mediapad-m5-root-thread.877718?html

Good luck!

Did you select the appropriate ROM version for your device variant? What is the firmware version you're trying to downgrade from?

Found this on the other forum, from somebody who failed to downgrade via normal method, but succeeded doing this:
1. extract dload folder so sd-card root
2. from update_sd.zip, extract update.app to same directory on sd-card
3. delete update_sd.zip
4. do normal upgrade: In the home screen click calculator, turn the tablet to landscape, enter ()()2846579()() , and the ProjectMenu page will be displayed. Go to 4. Software Upgrade > 1. SDCard Upgrade > OK).

I'm on 193 I think. I used the recommended firmware for the 10.8 WiFi. I will give this a try. Thanks

Dunno if someone can help. I've tried all sorts but my laptop running Windows 10 just won't recognize the tablet properly. The DC unlocked picks it up in PORT32 etc. But can't find the model number etc..my laptop keeps thinking it's a disc or hisuite. Done USB debugging. Uninstalling drivers. Restarting laptop and tablet. Manufacturer mode. Changing to MTP. Ive downgraded to fimrware 168 . Spent hours trying to get it to pick up properly so I can unlock the bootloader ?

I had similar problems which were solved by installing that HiSuite app. I think it installs some specific drivers that work while standard don't , and then DC unlocked recognized my m5. Try that.

What exactly did you do if you don't mind me asking? Do you select charging only or transfers when connect? Did you select MTP as usb protocol. We're you in manufacture mode? . Did you allow HDB from your tablet? Just seeing if theres a step I did wrong or missed or shouldn't have done

I just let HiSuite install automatically. When I plug in my tablet to laptop, it would auto run, and then you also see HiSuite as CD drive. Installed HiSuite and DC unlocker finally recognized it. I've never used HiSuite but it definitely supplied something missing on my laptop.

This was back in August. Not sure which firmware but I did not need to downgrade.

    DISCLAIMER: I'm not responsible for anything that happens to your device. Use the steps below at your own risk . Be mindful of the facts unlocking bootloader voids your warranty and also hard resets your device - ALL YOUR DATA, SETTINGS, FILES AND APPS WILL BE DELETED. These steps worked for me - I own Chinese version of 8.4" LTE model. I do not know if they will work for any other models of M5, including European versions, WiFi only version and 10" models.

    To execute the steps below you will need to obtain unlock code, specific to bootloader of your device. There is a slow, painful and free way to get it, and there is a quick and easy way to get the code instantly, which will cost you 4 euros. The slow way is to create Huawei ID, register on Huawei website and request the unlock code directly from Huawei, through dedicated link they provide. I do not use this method, so I don't have the link - do not ask. You will have to provide justification why you need it, such as being a developer and you bought the device to develop and make a living off of it - something Huawei support would find reasonable. In most cases they will not agree to unlock bootloader if you just tell them you want to install some roms. In this guide I will be describing the other method to get it done, which costs 4 euros.

    Follow these steps.

    1. Go to DC Unlocker website, register for an account (or login, if you already have one)
    2. Buy 4 credits (cost is 4 euro) using the Buy link
    3. Download the latest DC Unlocker client (pictures 1,2 below)
    4. Open the DC Unlocker client, click "server" tab on the right (picture 1) , enter your website login you created in step 1 and click "Check Login"
    5. Select "Huawei phones" from "Select manufacturer" dropdown
    6. On your M5, go to Dialer app, and type in *#*#2846579#*#* to open Project Menu
    7. Click Background Settings->USB Port Settings->Manufacture Mode
    8. Connect your M5 to PC via USB cable and return to DC Unlocker client
    9. Click the Search button to detect your device. It should be detected as "Huawei HiSilicon Kirin Android" (picture 1)
    10. Click "Unlocking" tab
    11. Click "Read Bootloader Code"(picture 2). It may not work on the first try, but don't worry - unsuccessful bootloader code reads do not spend your credits. Give it a few seconds, disconnect/reconnect USB cable and try again
    12. Copy and save generated bootloader code
    13. Download Huawei Multi Tool from the bottom of this page and install it
    14. Boot into download mode by powering off your M5, then holding Vol Down + Power keys simultaneously for a few seconds and then plugging in USB cable while still holding these 2 keys
    15. Open Multi Tool v8 and paste the code you got from DC Unlocker into "Get Unlock Key" input field
    16 Click "Use your key" button next to it (picture 3)
    17. On the bottom right click the green "Unlock bootloader" button
    18. You will get a bunch of warnings on your M5 screen about unlocking bootloader - press Vol Up key and then Power key
    19. At this point your bootloader will be unlocked and M5 will factory reset itself

    Note: using Multi Tool is optional. Instead, if you have ADB tools with fastboot installed on your PC, then after step 14 you can just use fastboot to unlock your bootloader, by typing "fastboot oem unlock <code>"
    Note 2: I don't do tech support via PM, so don't PM me for help or with questions. Use the thread instead, and some other XDA members or myself will probably help you. Good luck!

    Now I'm hoping some dev takes a shine to our phablet, and compiles TWRP build for it. It can certainly be installed now that we managed to unlock the bootloader :cool:

    Look guys, everyone here was new, asked dumb questions, made stupid remarks, and frustrated those who are contributing to Xda. Each of us has done it when we were new, someone of us are still doing it as senior members.

    My point; now that you're the one being frustrated by new users, don't threaten to pick up your toys and go home, if every dev here did that this place would be another social site. Report abusive users, don't "punish" the many users who show respect and appreciation for your time and efforts by walking away because a few new guys get irritating (remember when you were the one doing the irritating).

    Maybe it would do us all good to remember the days when we were the ones making people mad, asking stupid questions or arguing because we thought we knew when we really didn't.

    Those who are here to share your hard work, and be recognized, thanked, and grow your experience, please remember that the rules are for you as well as everyone else.

    If you are relatively new, and don't know how things work in Xda, or think you know more than someone else, or feel like arguing because your opinion is different than the one providing mods, Roms, etc. figure out a way to communicate the difference with respect and realizing that people who develop word here do it for free, they do it when they could be hanging out with friends or family, and they share it with us because they want to see if it works, what's broke, and get feedback on how to fix it. Not be disrespected by users who haven't put in that time yet. And the rules apply to you as well as everyone else.

    This thread has talented and experienced people in it, don't let all that get wasted and lost in arguing, bickering, and violation Forum Rules. Nothing productive come of that.

    No one is permitted to insult, be rude, or disrespect another user, regardless of your title, your skill level, or your time in Xda. Those who give up their personal time to develop mods for our devices deserve respect from those of us who use their work for free.

    tl;dr

    Be respectful to those who dedicate their free time to provide free stuff for us, every users should show respect to every user, report those causing heartache and frustration, remember you are here for the greater good, not the lesser evil. Be kind, and be an example of what you think Xda should be.

    • Once you're on the unlock page, fill everything out for a Wifi tablet with "Before EMUI5.0 selected".
    • Before hitting Submit, go into the chrome developer tools and under the sources tab, open up the file 'emui.huawei.com -> en -> publish static -> plugin -> unlock/template -> js -> detail.js?v.4.15'.
    • Click the '{ }' icon at the bottom left of the source pane to pretty-print the file
    • Scroll down to line 150 that should say "if(param.before5)". Right click the line number for that line and select 'add breakpoint'.
    • Now hit submit.
    • The submission should break on that line number, when it does (it'll be highlight), go into the console and enter "param.before5 = 0" (without quotes, followed by enter) to change it's value
    • Hit the '>' symbol at the top right of the source tab to resume submission.

    Got mine today for the CMR-W09 in a simliar way which may be easier for some:
    • Go to unlock page but select "Since EMUI5.0"
    • Fill in everything but IMEI
    • Open Konsole (F12) and paste
      Code: 
      $('#model').val('Tablet-Wi-Fi')
      second box should change from "Smartphone" to "Tablet-Wi-Fi"
    • Click Commit and receive unlock code

    The B181 update includes a security patch, which closes the backdoor used by DC-unocker to obtain the booloader unlock code.
    DC-unlocker comments this with: "Your device now runs new security system and no service will work even if it is detected as it appears [​IMG] Only possibly downgrade may help it."

    So, if you want to get the bootloader code, you must use B168 or versions below that.
    If you have already updated to B181 , you must try to downgrade.

    You can find versions with working common dload method via project menu and SD Card
    find it here: http://androidhost.ru/search.html
    Just search "AL09" or "W09" , "Mediapad M5" or "Madiapad M5" (Seems they have a typo maybe because of diffenent russian characters)
    I checked B181 and B168 (for W09) both have XLOADER 02 (checked via ante09 tool) , so this should work.
