How did you do it with dload? Should i unzip the file and put it on internalstorage/dload/HERE? I have too cmr w09 European m5

use the files @bombername provided. 168 is needed to properly read bootloader code with dc-unlocker.
the archive has the dload folder inside along with the required files and the correct structure
extract the whole /dload/ folder into the ROOT of your EXTERNAL SD card, not internal storage
open stock calculator app in landscape mode and type ()()2846579()()
in the menu, go to software update > sdcard update and wait for reboot

Yeah, one guy's first guide...

Not sure whether you're rude/sarcastic or just stunned ...

This guide is more or less a community effort of Pianoralf,JamesBott and myself (I was the one asking stupid questiond and subsequently composing the guide ...) over there (I think I read JamesBott on xda as well ...). As I was the one doing all the testing and suffering, I wrote it. Why would it be something different if it was not "one guy's first guide"? Didn't we all start as "one guy" with a "first guide"?

I am afraid, I do not have any screenshots but those in the post on android-hilfe.de
Apparently it doesn't work for the Mediapad M5 lite, but for the "original models", I think it worked.

A bit off topic, but does anyone know of a solution for restoring the stock calculator app without doing a system restore? I tried an apk install of supposedly "stock" calculator but it would not install. Questionable if it would have functioned properly anyway.

I have the SHT-W09 8.0.0.173(C567) M5 and am hoping to downgrade and use dc-unlocker.

Thanks

I'm sceptic or at least I was.
You now proved me wrong :
dload downgrades on locked bootloader are in fact possibles.

Now I wonder if this downgrade ability is devices specific or it worked because of the dload archives used...

It's really nice dload downgrades are working for SHT and CMR locked devices.

I am having much difficulties trying to downgrade my SHT-W09 (C00). It's currently running 8.0.0.185
* I downloaded the firmware (e.g. SHT-AL09C00B125 / 8.0.0.125) off this site http://huawei-firmware.com/?load_page=search&q=mediapad+m5&page=1
* From the update.zip, I extracted the UPDATE.APP and put it in the SDCard /dload/UPDATE.APP, and trigger a software upgrade.
The EMUI would attempt the upgrade and it would fail after 5%.
Any idea what I'm doing wrong?

Just a thought, I think /dload/UPDATE.APP has to be on *external* SD, if you haven't tried that.

Yep, I did use an external SD card, and it stopped updating after 5%.
Hmm, I was hoping you had messed up ? because I dl'd from the link you gave [thanks, btw] for my SHT-W09 8.0.0.173(C567) and am planning on trying downgrade to build 167. Seems that trying and failing didn't hurt your M5, so that gives me encouragement to take the plunge.

Build 167 is supported by dc-unlocker, right? Says in earlier post that it has to be 168 or lower, so I think I'm good.

Yikes. Glad I found this thread. I was about to buy the M5 8.4, but since Huawei is making root/unlocking difficult, I'll buy a product from one of their competitors instead.

I too own the SHT-W09 [C567 type, but not sure what that means]. From what I understand, as long as you are at build .168 or lower (pretty sure mine was .158 or something when I bought it, then ignorantly updated--now at 8.0.0.173) the dc-unlocker works.

If you buy it, just don't update above .168 and--I think--you'll be fine.

Great tab, but would not have bought it if I'd known about LOCKED F'N BOOTLOADERS--no more Huawei for me.

Hey guys, I need some advice.
I have a Huawei Mediapad m5 10.8 (432) and I successfully downgraded the bootloader (from .181 to .168). I also got an unlock code from dc unlocker, but now I'm stuck at step 14. For the love of all that is holy I can't boot my device into fastboot mode. I switch it off, then hold down both volume keys + power key. The device vibrates after a few seconds, I connect the usb cable while still holding all the keys, then one of two things happens:
1. After about 10 secs I get the message "Software install failed - Reboot device now". I can only tap reboot and the device reboots into "normal mode".
2 .After about 10 secs I get the message "Installing software", the devices shows a loading circle at 5% done and reboots after 2 minutes into "normal mode".
The tablet works fine after either reboot, no harm done.

Anyone knows why I can't get into fastboot mode?

Thanks, skyvahaerie

You're entering firmware/dload mode.
For fastboot, plug phone to usb to computer and use only Volume DOWN key.

    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:
    17
    To enter Project Mode on Wifi only tablets, open calculator and enter () () 2,846,579 () (). On 10.8" tablet, it will need to be in landscape mode to get all the calculator symbols to show.

    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.
