EVERYTHING IS ON YOU!
So. To unlock Bootlader, add Custom Recovery TWRP and root we need to do a little preparation. First of, It will cost you €4 to unlock the bootloader in this way, but given that your warranty is absolutely immaculate, it's worth every penny. You CAN get the code for free from huawei but at the same voiding your warranty.
We start with activating "Developer Options".
We do this by going to Settings -> About Tablet.
Then you click on Build Number 5 times.
When you have enabled the Developer Options, go to Settings -> Developer Options.
Once there, you should look up "Enable OEM Unlock" and select it. It will ask again if you are sure. Press yes.
After this, we need to change the USB port to something called "Manufacture Mode" which you do by opening the calculator (Huawei's own) in landscape mode
then type exactly this: () () 2846579 () () =
After pressing the = sign, then a hidden menu will show up. Do not mess around in here if you do not know what you're doing ...
Now you enter the "Background Settings" -> USB Port Settings -> Manufacture Mode and select "Manufacture Mode".
Select and close the menu. Back out to Home.
Now you must get HiSuite available here: http://consumer.huawei.com/minisite/HiSuite_en/
This is for you to get the right drivers. Just install and start up.
Connect the MediaPad to your computer with the USB cable. The MediaPad will ask if it's ok with USB debug. Take the "Always Allow" and ok.
Check in your PC Control Panel -> Device Manager so that it looks something like this.
Now let's get us a program called DC-Unlocker client. What it can do is unlock your SIM and get your Bootloader Unlock code that is unique to your MediaPad. This code can also be ordered from Huawei but then you can kiss your warranty
bye-bye. You will have to pay 4 Credits (€ 4) for the bootloader code. To unlock the SIM, it will cost an additional 4 credits. It costs 2 credits to relock the bootloader if needed for warranty issues.
Download DC-unlocker client here: https://www.dc-unlocker.com/downloads/get/B4oUVw8X
Take the opportunity to make a user as well as buy credits here: https://www.dc-unlocker.com/buy
Select New User and enter your desired username and email address. Once you have paid for your credits you will receive the password to your user via email and / or directly after managed payments (PayPal).
Start the DC-unlocker client as an administrator (Right-click DC unlocker2client.exe and select "run as administrator")
Now, change the Select manufacturer to "Huawei Phones". Leave the Select model on Auto Detect. Now press the magnifying glass.
Now it will look like this when the program has found the Mediapad.
Now, open the Server tab and enter your username and password you provided when you created your account. Then press the Check login to see how many credits you have.
Now open Unlocking tab and select the "Read bootloader code" (This will cost 4 credits)
Now your code is shown at the selected area. Print / Save it down somewhere safe because that code is unique to your MediaPad and it will cost you 4 credits to get it again.
Now that you have your bootloader code, we need to restore the MediaPad to HiSuite mode again instead of Manufacture mode. You do this by redoing the step with the hidden menu with the calculator at Step 5. Go to the same page but select HiSuite instead of Manufacture Fashion.
Now that we have Bootloader code, we have to arrange ADB and Fastboot to send some commands to the MediaPad.
ADB and Fastboot I have collected here: https://mega.nz/#!ck8CDJra!XsExtdNcw...1lV7G9vXIYrhe8
In that folder I also have TWRP (twrp.img) for MediaPad M2 and a theme that changes the language to English (ui.zip) as TWRP is in Chinese.
Unzip the folder in your root (c:/) or wherever you want.
Now open the command prompt (the Administrator) in the computer and navigate to the folder so it looks something like this.
Start the MediaPad in fastboot / Recovery mode. This is done by turning off the MediaPad. Inserting the USB cable from the device to the computer while the MediaPad is off and quickly pressing the Power button + volume down button until this image appears.
We start by unlocking the bootloader, type: fastboot oem unlock your-boot-unlock-code (So: fastboot oem unlock 8794898763874)
Now you have unlocked your bootlader. Now type: fastboot reboot
The MediaPad will reboot.
Turn off the MediaPad and repeat Step 19.
When you are in fastboot / Recovery mode, enter the command prompt: fastboot flash recovery twrp.img
Now you have flashed TWRP Recovery.
At the command prompt, type: fastboot reboot
The MediaPad will reboot.
Now, connect your MediaPad to your computer and navigate to the internal memory. You will find a folder called TWRP.
In this folder, create a new folder and name it "theme". In this folder, copy ui.zip from my adb folder.
You can also take the opportunity to copy the BETA-SuperSU-v2.67-20160121175247.zip to your MediaPad (suggested internal memory root or download folder or wherever you want as long as you know where you have it).
Now we open the command prompt again and type: adb reboot recovery
Your MediaPad will reboot and suddenly you are inside the TWRP Recovery.
Optional: You can also enter recovery by booting the tablet by pressing power button + volume up. Keep holding volume up until you enter TWRP
I recommend that you make a TWRP backup of your MediaPad BEFORE rooting... Just incase
Install BETA-SuperSU-v2.67-20160121175247.zip and you have ROOT.
Now you are ready!
Install an app that allows you to reboot to recovery easy for example "Quick Boot" in PlayStore.
Do you have any any questions, just ask them here!
