[Guide] Unlock Bootlader, TWRP and Root your Huawei MediaPad M2 8 - 10

As usual with this stuff. You do everything at your own risk. I am not responsible in any way for what you manage to achieve, either good or bad.
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.
Step 1.
We start with activating "Developer Options".
We do this by going to Settings -> About Tablet.
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Step 2.
Then you click on Build Number 5 times.
Step 3.
When you have enabled the Developer Options, go to Settings -> Developer Options.
Step 4.
Once there, you should look up "Enable OEM Unlock" and select it. It will ask again if you are sure. Press yes.
Step 5.
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 ...
Step 6.
Now you enter the "Background Settings" -> USB Port Settings -> Manufacture Mode and select "Manufacture Mode".
Select and close the menu. Back out to Home.
Step 7.
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.
Step 8.
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.
Step 9.
Check in your PC Control Panel -> Device Manager so that it looks something like this.
Step 10.
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).
Step 11.
Start the DC-unlocker client as an administrator (Right-click DC unlocker2client.exe and select "run as administrator")
Step 12.
Now, change the Select manufacturer to "Huawei Phones". Leave the Select model on Auto Detect. Now press the magnifying glass.
Step 13.
Now it will look like this when the program has found the Mediapad.
Step 14.
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.
Step 15.
Now open Unlocking tab and select the "Read bootloader code" (This will cost 4 credits)
Step 16.
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.
Step 17.
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.
Step 18.
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!XsExtdNcwGX7zMW9F6uYo155YuMd71lV7G9vXIYrhe8
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.
Step 19.
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.
Step 20.
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.
Step 21.
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.
Step 22.
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).
Step 23
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
Step 24
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!

IF it says OK you have successfully flashed TWRP.
And the TWRP folder won't appear until you have booted in to recovery at least once. The thing is that it will be in Chinese unless you do the step before booting in to recovery.
Therefore you create a folder in sdcard/ called TWRP and in that folder another folder that you call theme there you add the ui.zip.
So complete address is /sdcard/TWRP/theme
(Note, big letters on TWRP)

i have created folder called "TWRP" by myself, then i have created "theme", copied that ui.zip and? nothing changed..
IF i reboot device once again to recovery=>default screen with fastboot will appear. I even tried to download an app from store called "quick boot", downloaded=>choosed to reboot into the recovery and app stopped working (because it was saying that i dont have root)

You have to use the right command:
adb reboot recovery
You can also enter recovery by booting the tablet by pressing power + volume up. Keep holding volume up until you are in TWRP.

Still can not boot into the recovery. I would like to inform you, that i do own 8.0 MediaPad M2 Pro version (which comes with 3GB of RAM) (cos i saw you have 10.1)

Don't forget the thanks button

I did not you deserved it.
And one more thing to all: in other thread one guy was talking about not working xmod (xmodgames properly) even if you have your device rooted (by this method). After like 10min i finally has launched even xmod (because most of all you need for this really true method of root), i had some issues with installing etc. but now i can play my CoC with that
hopefully you wont take it as a spam, take care. bb

I have a Huawei M2 8.0 and don't have the "Enable OEM Unlock" option in the Developer Options
Any ideas how to proceed further?
EDIT: Nvm, I proceeded with the rest of the guide and it worked fine.. I didn't have to enable OEM Unlocking.
BTW, your TWRP link on Mega is broken - it's asking for a decrypt key. Luckily I found a different TWRP somewhere else and that appears to be working fine.

The system has been destroyed

I was using the Mitool tool, and suddenly the machine shut down and the message "the system has been destroyed" appears and it does not start anymore, the only option I have access and the fastboot, would anyone have the solution?

Is your bootloader unlocked?
Did the PC shut down or the phone?
If your bootloader is locked you will need to open the back of the phone and flash a new firmware with PC and pressing the test point on the inside of the phone.
If unlocked you can fastboot the firmware as you normally would

You can flash images with Mi Flash on locked bootloader no problem.

They can try but if recovery isn't accessible then fastboot is the only option and without unlocked bootloader you cannot use it.
Test point is then the only way.
Obviously its best to try flashing without opening the phone first.

Wtf! You can't use mi flash tool unless your bootloader is unlocked

The problem was tense, but it's already been resolved. I find it hard to understand more I will try to explain.
-------------------------------------------------- ------------------------------------- 1º It was with the Global Beta rom and the bootloader unlocked and installing the TWRP for the mitool, however for lack of attention I selected the option to block the bootloader.
After confirming the bootloader block by mitool, the cell phone appeared the message "the system has been destroyed", and it was restarting on this same screen, the only option I had access was to the fastboot.
Since I had access to the fastboot, I tried to install the rom by the miflash only that it gave the message "remote: Erase is not allowed in loke state".
4º After despairing and thought to open the cell to do the testpoints method.
5º Since probably the bootloader had been blocked by the mitool, I decided to enter the site and ask Xiaomi to release the code to unlock the bootloader again.
6th I put the chip in another device and thanks to the holy protector of the cell phones Xiaomi quickly released the code, I did process to unlock the bootloader and the cell phone ran again.

The bootloader gods have smiled upon you this time

Hello! I have locked bootloader with "fastboot oem lock". I was in panic, but randomly I press "Volume -" + "power-on" and my Mi A1 have loading in Fastboot mode, where I was able to unlock bootloader again.
Hope, this can help you.

HI there I also stuck in the same condition and it seems your phone's bootloader is locked now, this happens because you root the phone or installed custom libs or twrp in it and locked the bootloader. So unlocking the bootloader will fix this problem. You can unlock it by going into Fastboot mode (pressing power button + volume down (-) button) and then with platform tools you can unlock it again by typing "fastboot oem unlock" and then "reboot".
I hope this will help someone

same issue in redmi note 4

Reflash your rom with fastboot and hope you haven't messed up anything related to your data so you can still use and have access to it.

Cool then ?

I had the same problem today. my phone was distroed when I tried to install Gcam.
my phone was not unlocked so that the flash of the new stock of the ROM was not possible. The solution is to connect the phone to a PC in fastboot mode and from the platform tools in cmd to type fastboot oem unlock. After that, I did not have to have a flash phone. Everything worked as if I only had to backup the data.
now I have a new phone.
People, with Mi A1, cling to two things - slot A or slot B and lock or unlock. The easiest way to do this is a cardinal error.
Greetings.

Same thing happened to me. Had global rom with bootloader unlocked, then I installed TWRP and reinstall MIUI 10, as well as no-verity and Magisk. When installed the phone showed some issues with the proximity sensors so I decided to reinstall, after installing and booting MIUI showed a message, "the device is locked", I couldn't connect to the internet to unlock it, so I decided to do a fresh installation through miflash, after a couple attempts all of a sudden TWRP was not there anymore. Now the bootloader shows unlocked on '''fastboot oem device-info'''. Now the real problem: miflash doesn't work because bootloader is locked, I didn't unlocked it in the first place so I cannot do a fresh installation through miflash, when booting TWRP it shows the message, The system has been destroyed....
I tried miflash, fastboot oem unlock, fastboot recovery flash for TWRP, fastboot -w then fastboot flash recovery ....zip. Absolutely nothing is working.
How did you make it work exactly?

With locked bootloader I got no chance to flash anything. Neither fastboot nor MiFlash - any solutions? Also would be helpful to enabke USB Debugging via fastboot. Anyone knows?

If you brick your device on the way as it happened to me... check: https://forum.xda-developers.com/showpost.php?p=77755947&postcount=11
These guys helped me unbricking my mi8 using EDL (Test Point) and Mi-flash!

I want to sell my Google Play app developer license.
Please email me or call me if you are interested.

I got a bricked Mi 6 from a friend. He was trying to flash firmware, and somehow messed up. Trying to boot normally or into recovery showed "The system has been destroyed". `fastboot continue` did not work. Bootloader was locked ( = no possibility to do fastboot oem unlock). On top of that, the phone only accepted fastboot commands right after the usb cable was connected ( => I had to run a fastboot command, like `fastboot getvar all`, fastboot would output `< waiting for any device >`, then I connected cable, and it would work). Running fastboot commands later resulted only in fastboot hanging / getting stuck, with no output, can not be terminated with ctrl+c unless cable was disconnected.
I got myself a windows computer (I use linux), tried to do bootloader unlock. Failed on "add your mi account in Settings -> Developer -> blablabla" - no way to do that with a bricked phone. Then I found out about EDL (Emergency download) mode. This is what worked.
The only way to get into the EDL mode in this state was the hardware way (shortcutting the pins / "PCB test points"). Search online for "mi 6 edl mode testpoints". Basically, you have to:
1. remove the rear cover
2. remove the screws on the plastic part above the battery, remove the plastic piece
3. disconnect the battery (shorter connector on the left side)
4. shortcut the pins using a tweezer (the pins are just above the battery connector)
5. while the pins are connected, connect the USB cable
6. check in device manager that you have "HS-USB QDloader 9008" in the COM devices
7. use mi flash tool to flash the fastboot firmware
The pins (from https://www.mobilerdx.com/2019/02/xiaomi-mi-6-test-points-xiaomi-mi-6-edl-mode-pinout.html):

And after you succeed, maybe unlock your bootloader, so that you don't have to do this again

Any way to enter EDL mode without disassembling the phone?

Vol up/down + USB cable doesn't work, and I read one post that says the deep flash cable doesn't work either. Bootloader is locked.
I have the full body ceramic version, so there aren't any disassembly directions available so I could take it apart and ground the EDL points...
Current ROM is just boot looping, wiping data doesn't help, and only ROM I seem to be able to flash is the same one (latest global beta).... Just want to downgrade back to global stable.
Any info would be greatly appreciated!

Can't you boot to fastboot? What's the error when you attempt to flash anything else? Can you access TWRP?

Yes. When you start it from recovery, it says it needs ADB, and reboots the phone to OS (which bootloops - no way to activate ADB in OS).
Edit: Same with starting XiaomiTool when in FastBoot - it needs ADB enabled from the OS....

Hello, hello! Here's the link how to disassemble mix2:
1obzor.com/news/razborka-xiaomi-mi-mix-2.html
after opening here is the instruction on how to enter EDL mode:
en.miui.com/thread-1351514-1-1.html
links without the htts: // prefix
since I'm a new member

This was happened to my xiaomi Max.
i tried using fastboot to boot into EDL, it didnt work.
using fastboot-edl -> reboot.bat, it show success message but actually my phone only restarted and stuck in "Mi" Logo.
what i did to boot into EDL are :
- While phone still connected to pc and phone in fastboot mode i try to hold the power button
- After the screen blinked (it restarted), i pressed both vol + and vol - and after i hear a plug in sound in my PC Windows i release the power button
- Then the screen will stay Blank (With background light) but after i refresh MiFlash application, it will detected as COM20 or something.
- Then i do flashing and it works!
Hope it will help to solve your problem

To enter EDL on mix 2 without disassembling. Boot the phone into bootloader then you type "fastboot oem edl" on your computer then you can flash the phone normally with mi flash tool. Hope this suggestion can help!

the miui version cant be installed on this device

I am an idiot i have self inflicted this issue. I flashed from 8.11.8 to 10.0.0.1 i mistake clicked flash and lock.bat now the device is locked and will not boot. Got deep flash cable but not able to switch off the device to get into 9008 mode. please someone direct me. I am getting frustrated and loosing hope. Cannot boot into edl as bootloader locked. cannot recovery as I have no twrp. cannot unlock as device is not bound to account. cannot debug mode as device will not boot to OS. I have truly made my life complicated not purposely. cannot shutdown the device to get into Deep flash mode
Thank you people, apologies for wasting your time.

Same situation.. still trying to find a way to get out of this. But i can help you somehow as i figured out how u can switch off the phone.
1. Copy and rename any file to twrp.img and save it in a folder
2. Open cmd and change directory to where u saved the twrp.img file
3.Just boot into fastboot and type this command
fastboot boot twrp.img
It will try to push this to your phone ane eventually fail. You will get a message on your phone saying "system destroyed and press power button to switch off"
Thats how i switch it off each time lol

2. Open cmd and change directory to where u saved the twrp.img file
3.Just boot into fastboot and type this command
fastboot boot twrp.img
It will try to push this to your phone ane eventually fail. You will get a message on your phone saying "system destroyed and press power button to switch off"
Thats how i switch it off each time lol

FP4 stucks after unlock the bootloader

Hello together,
today i tried to install /e/ OS on my new FP4.
I did everything like in the official description:
> ## Unlocking the bootloader
>
> 1. Boot the device
> 2. Enable and connect Wifi
> 3. Enable Developer options
> 4. From developer options, enable OEM unlock
> * Get the unlock code from [this site](https://www.fairphone.com/en/bootloader-unlocking-code-for-fairphone-3/) and enter it
> 5. Reboot on fastboot by running the command in the PC console `adb reboot bootloader`
>
> 6.*Tip:** All the console commands are run on an adb enabled PC and in the `adb` console.
>
> 7. Ask for unlock with `fastboot flashing unlock`
> 8. Approve with <kbd>volume +</kbd> then <kbd>power</kbd>
> * The device proceed with a factory reset, and automatically reboots
At 8 i maybe made a mistake, when you are in the fastboot mode, you can choose different options, i choosed something like FFBM or something like this. Then the device restarted and since that it always shows the "blue dots" like in the beginning but nothing more happens, since hours.
I turned it off and on again, without success.
I can not load the fastboot again via ADB, because the device is not recognized.
If i try to use the volumeUP or VolumeDOWN at the startup, nothing happens and it restarts again after a few seconds.
So there is no way for me to enter the fastboot mode again.
So I have two questions to you, lovely community.
One is, can anybody help me?
Second, can somebody tell me how the different options are called in the fastboot mode, so i can google it and do more research.
THANKS a lot and sorry for my english :slight_sm

Hi,
Are you able to launch the stock rom or are u stuck on bootloop or bootloader page ?
If you can launch the stock rom, enable oem, debugging and unlock bootloader in developper options.
Then connect phone to pc with the cable and type adb devices
see if the phone is recopgnized.
Then adb reboot bootloader and do all steps of the official guide.
If you use Windows I suggest you to put all file to your adb folder, type CD /path/to/folder/
And copy paste all commands at once, this will avoid error of mishandling during fastboot operations.
If you stuck on a "waiting for phone" when you are in fastboot mode, check you driver, or test with a linux machine or see Hulk's solution here
If you stuck on a bootloop just use the key combo to enter bootloader. check on the bootloader is everything is ok (unlock) if not redone steps to unlock bootloader, then flash recovery from /e/ os folder fastboot flash recovery recovery.img
Then enter in recovery use the combo key to have the menu choice between bootloader, recovery... then enter recovery and wipe data...
Then restart the official guide of /e/ os.
You may ask on /e/ os forum too many much more Fairphone user are there and can help you (link i gave you above).

Hello,
thanks for your reply.
I posted the same comment at the /E/ OS Forum as well.
I Can not load the stock rom, there are only this blue dots circling around for hours:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",

"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
I can not enter anything else, using ADB is not possible because the device is not recognized and the combination of volumeUP and power or volumeDOWN and power only restarts the device.
Do you have a FP4 and you maybe can tell me which options in the top of the fastboot menu you can choose?
Something like reboot and so on.
I will try the solution in your link in a few hours when i have more time.
Thanks a lot and BR

Bootloader menu options are "start / restart bootloader / recovery mode / power off / boot in ffbm / boot to qmmi"
I don't understand your problem if your bootloader is unlock you must have accesss to bootloader.
Are you sure you didn't relock bootloader before checking the rom is correctly installed ?
Contact /e/ support to have the precise combo key to enter bootloader. sometimes it change from phone to phone.
Does your computer works well with adb and fastboot before ? did you already flash rom ? Maybe a driver is missing or adb/fastboot is not on the last version. You may try with a linux pc to aovid those problem.

How to Boot into bootloader mode
This section will be relevant later throughout the guide, when you need to reboot into bootloader mode.
Remove any USB-C cable and turn off your Fairphone 4
Tip: If you cannot turn your device off, remove the battery for about 5 seconds, then put it back in.
Press and hold the Volume Down button.
Insert a USB-C cable connected to the power (can either be a power outlet or a computer).
Release the Volume Down button as soon you boot into bootloader mode
For more details on how to erase the data on your FP4 refer this guide
I just try this and works great : power off the phone (if you can't just remove battery as said), press vol down and plug the usb cable
My phone has the bootloader locked and flashing locked and it works. try this

You are my hero.
I dont know how many times i read that but i was to stupid to do that correctly.
Now i tried it again and it worked well!
Thanks a lot!
Problem solved.
Just for other idiots like me, i choosed the option boot into ffbm into the bootloader menu, this was my mistake.

The Phone will finally boot up with the (OnePlus Global Boot Animation Logo) indicating the Conversion was successful. It will take a long time to boot up into Android that's normal for the first boot!
Note: If it didn't boot your phone into (Fastbootd Mode) when you clicked on flash-all.bat the 2nd time That's ok. just turn the phone off again. Boot back into Fastboot Mode and try again and click on flash-all.bat once more. If it fails on second Flash you need to update your Bootloader driver!! So go back & check out the USB Driver's Guide https://forum.xda-developers.com/t/...ficial-usb-drivers-bootloader-driver.4558965/

Select language. Select Wipe data and cache > Erase Everything (Music, pics, etc) > Tap on "This can not be undone, continue?". Now Reboot system from "Reboot" option."
13I recommend locking your bootloader once completed with the guide, unless you plan on rooting or installing custom roms.
Plug your phone into the PC, Turn USB Debugging on then Boot into fastboot mode.
Open a cmd command prompt in platform tools root folder.
Type fastboot flashing lock hit enter.
It will say do you wanna lock your bootloader hit continue
14Last step is to Disable your updates thats if u don't want Android 12 update Notifications! I've made a guide here https://forum.xda-developers.com/t/guide-disable-system-updates-permanently.4592381/

The Benefits of Global/International Firmware Conversion
Click to expand...
Click to collapse
Completely removes T-Mobile Apps and any underlying Software (there aren't a lot, but why not completely gone!)
Use Dual Sim supported by the hardware & the ability to use other carriers.
Get on the faster firmware release schedule of stock Global firmware because it doesn't need to be certified by T-Mobile, which are always generations behinds.
You can now Root your OnePlus 7T & install Magisk & use Magisk Modules.
You can OEM unlock your Bootloader & put TWRP & install Custom Roms if you like.
Conversation will NOT change your Model Number it will remain a "HD1907"

Maybe a noob question, but would there be any downsides to this, such as loosing access to certain radio frequencies?

Nope not at all. It's an upgrade in my opinion better battery life as well. Just dnt upgrade to Android 12 or 13 on a Converted 7T & your golden.

I used metro PCS after conversion & I never lose connection neither does my wifi which is Comcast.

@Birdflyer Did you try to convert over to global yet?

Hello, I am having a lot of trouble with the MSM tool. I can get the phone into edl mode and start the msm tool, but it quickly disconnects the phone ("status of connection" shows "N/A") and the status of communication is "setting firehose communication data transmission ". On the device manager it shows the phone as unknown USB device (device descriptor request failed). Could this be because my phone is on android 12 or is it a problem with the PC? Luckily, this seems to result in nothing happening to the phone, and after plugging it into the charger I can reboot normally

Yes thank you I got it fixed, I think the bootloader driver wasn't installed correctly so I reinstalled that, and I updated usb drivers through the windows update (these were just the drivers for my PC, not related to the drivers I needed to install to convert the phone). It had some trouble at first connecting to my PC in fastboot but I got it working eventually and now the phone has been converted!

That's means you didn't completely convert over! Power the Phone OFF then boot into Fastboot Mode by pressing vol up & vol down plus power at the same time. Then go to Platform Tools folder on your PC & click on flash-all.bat again it should boot your phone into Recovery Mode on the second flash all! Then it will boot your phone into Global Firmware finally & your wifi will be restored.
