Guide to unlock Huawei Ascend Mate bootloader
I AM NOT RESPONSIBLE FOR ANY DAMAGE TO YOUR DEVICE. DO IT AT YOUR OWN RISK.EVERYTHING WRITTEN IN THIS DOCUMENT WAS TESTED ON MY PHONE.
After playing with my Mate I found a way to unlock the locked bootloader. If your bootloader is unlocked you can flash custom kernel , recovery to your phone.
The files used to unlock the bootloader is from P6 KitKat firmware. These two files are for efi and fastboot partition. Flashing only these partitions can avoid problems with mismatching modem firmware. The process was tested on official B221 firmware , but should work with any firmware. Reflashing a stock firmware(as I know there are only firmwares for Mate only with locked bootloader) with dload will relock the bootloader.
Unlocking process need proper adb and fastboot drivers installed. I use this driver :Huawei handset drivers for windows
Guide in pdf format
If your adb and fastboot drivers are correct you can start unlocking the bootloader.
If you want to unlock the bootloader and install Twrp recovery use this package :Bootloader unlock with TWRP install
Bootloader unlock with TWRP install mirror
This way powering on your phone with volume up button hold TWRP recovery comes up instead of stock 3e recovery. If you want to use the dload method to install a stock rom you have to restore the stock recovery.
Stock B221 fastboot flashable recovery
Stock B221 fastboot flashable recovery mirror
The other package just unlocks the bootloader .Bootloader unlock.
Bootloader unlock mirror.
Turn on USB debugging on your phone (settings->developer settings)
Start the package.
File extraction starts.
Command prompt window should appear.
Your phone restarts in bootloader mode.
Efi partition is flashed.
Fastboot partition is flashed.
Your phone restarts in bootloader mode.
Your bootloader state is displayed. (should say bootloader unlocked)
Your phone restart in normal mode.
This is what the packages do :
.\adb wait-for-device
.\adb reboot bootloader
.\fastboot flash efi efi.img
.\fastboot flash fastboot fastboot.img
.\fastboot reboot-bootloader
timeout 2
.\fastboot oem get-bootinfo
timeout 10
If it says your bootloader is still locked you can try the following:
adb reboot bootloader
fastboot oem unlock UUUUUUUUUUUUUUUU
If you want to restore stock rom and recovery here are the packages.
Recovery restore package for B221
Recovery restore package for B907
These packages restores the original efi and fastboot partition and then restores the stock recovery. These packages do the opposite as the unlock bootloader , however my phone stayed unlocked. Also this package solves the problem when the stock recovery stuck at the begining when trying to flash a stock rom using dload method.
WARNING:If you plan to flash a rom not made for Mate , always check that it does not overwrite other partitions then boot, system, data, cust. If the install package reflash the modem do not install it as it can hard brick your device.
For updated versions of permanent TWRP recovery check my thread here
Thanks to surdu_petru for the initial device tree to compile twrp.

Thanks joe....atlast bootloader unlocked..
One more thing i installed Fly UI OS from p6 and replaced with stock HAM boot.img....OS is not booting properly getting lots of FC's...
Does CM10.1 require different kernel or do we need to change any setting?

CM 10.1 may need some change in kernel or/and its config. Init.rc files needs modifications (framework , init.d support) , and it can happen that the init binary need some mods in cm source for proper working.For example wifi firmware path as on g510 . The standard cm init uses 2 firmware path , while the g510 init uses 4 to properly load wifi firmware files.You can check it on my github.
I am planning to compile a cm rom for our device , but the bootloader was the first step.
Awesome news mate ...
Finally someone can make goodies on HAM !
You can take a look also on my CM11 development project for P6, maybe you will make one for HAM !
Good luck !
Nice , very nice
Yes !!! This is best news on Ham. Thanks

Now this is a great Birthday present for me..
HAM Finally can be UNLOCKED.
i havent try yet but just wanna ask few questions.
1. Since now i'm using Hyd52Rom from Husen, can HAM be Unlocked with this Rom running?
2. Whats the best choice of current rom running for Unlocking?
maybe its sound stupid but its me (non-devs brain and only a user who dare to test..)...
Thanks guys.
You can unlock your phone using any rom. The only thing is needed turned on usb debugging. Of course the drivers on your pc should be installed .
After unlock check my other thread and update your permanent twrp to 2.6.3.2.

Looking forward for testing Compatible Roms.
Any suggestions highly appreciatable.
Thinking of trying P6 roms but not sure if theyre compatible

Can i use this method only for HAM or can i use this for my P6 also?

It should work on P6 too , but for P6 there are stock roms with unlocked bootloader.(KK beta).
If you want to use it on your P6 , use unlock bootloader only , and flash permanent twrp made for P6.
Of course permanent twrp for Mate will work on P6 as well , but the device identifier will be hwmt1_u06 and not hwp6_u06 which can cause assert errors when you try to flash a recovery flashable P6 rom .
I know. But i search for a way to use this on B125 international. In the CN it is to easy

Hi,
I can't flash [ROM][JB4.2.2][HAM][ HYD52ROM V5] [Superfast,Stable][V5 7-02-14]
from TWRP 2.6.3.2 . Everythings go right but on reboot the device never end logo.
I need to relock bottloader and start again whit dload. I have tryed flashing same zip from tmp recovery on locked and everything is working. i will to know if is a rom problem or twrp or unlocked bootloader.Also i have try buckup from HYD52ROM V5 whit twpr 2.6.3.2 and restore rom, after a factory reset, but was a id mismatching and no user app.
I will try to unlock and no permanent twpr, but use a cwm tmp whats happen. i will report
Edit: whit unlocked bootloader and tmp twrp
2.6.3.0 from sordu_petru recovery flash of same zip ad no problem.
hello!
After trying multiple times, my ZF2 doesn't install an update. I click install it goes to recovery screen and then after a few seconds, dead bot appears. I think I gotta flash a full system image. 2 Questions :
1) Will I Lose All My Data After Flashing A System Image?
2) In this link ( http://forum.xda-developers.com/showpost.php?p=61687943&postcount=3 ) there are many firmwares. The list is as follows :
V2.20.40.61 CN
V2.20.40.59 CN
V2.20.40.59 WW
V2.19.40.21 JP
V2.19.40.22 WW
V2.19.40.20 WW
As you can see, there is no WW firmware after 2.19.40.22. So should I just download the "V2.20.40.59 WW" and flash it?
Thanks in advance!
1st, if you want root then go to the pre-rooted rom thread in Android Developement. You can get 2.19.40.90 pre-rooted. to update using fastboot method.
Be aware we are up to 2.19.40.97 with updates...
If you want to unlock your bootloader then I'd do it now as it is better, a lot of people are having trouble with fastboot flashing when they unlock their bootloaders after 2.19.40.22 firmware.
You shouldn't loose your data but best to backup just in case.
After the last OTA update, my Moto G5 started to boot with the following warning:
"
Your device has failed verification and may not work properly.
To learn more visit:
motorolacom/unlockbootloader
ID: N/A
Your device will boot in 5 seconds
"
It also started to restart randomly.
I did some research on the web and found out that this warning appears when someone unlocks/roots the device.
The problem is that I aver never unlocked the bootloader or rooted the device.
When I boot to fastboot it says "OEM Locked" and the app DevCheck says that I am not rooted.
It seems to me that the update corrupted something and now some piece of software flags my device as unlocked.
Besides the irritating screen, some apps are not working properly or cannot be downloaded from the store.
I tried to reset to factory settings and wipe caches. Problem still happens.
I'd like to know if you guys know a solution for this problem.
I saw on another post that this problem was happening on some Verizon Moto Zs and they provided a software to reinstall the rom
Unfortunately, Motorola has not released a software to do the same to unlocked devices.
My ROM version is: NPPS25.137-33-6 (yeah, there is an "S" that I don't find in the roms available here)
The baseband is: M8937_8000.122.02.45R
(CEDRIC_BRAZILDSDS_CUST)
I was thinking in loading the rom into internal memory, reboot in recovery mode and flash the rom using the option "Install package from zip".
Do you know if it would work without an unlocked bootloader. Is it safe?
Thank you for the help,
Don't know if you can flash the boot logo without an unlocked bootloader but if you can here it is
Put phone in fastboot mode
Download logo from link below
Enter the following in a windows command prompt where you have fastboot files (Google to learn howto install Android sdk) & the logo file
Code:
fastboot.exe flash logo logo-g5-fix.bin
http://drive.google.com/file/d/0B-idWfPYugGvREJaR3B0UFIxUkU/view?usp=sharing
If you can't then you have no option but to wait for Motorola to fix it if you really haven't modded your phone
TheFixItMan, I really appreciate your answer.
But in that case wouldn't I just be changing the warning screen?
The problems with Netflix and other apps would remain.
I need something to fix the cause of the problem.
Have you guys heard about that problem before?
This guy had the same problem, but verizon patched it:

You can go back to stock using ADB update or by flashing VERIFIED images in bootloader mode. This will work even when bootloader is locked.

To flash using bootloader I need just to copy the .zip in the internal memory, reboot in reboot in bootloader mode and select the option "install from .zip file"?
Where do I find the verified image for my device?
If I flash an unverified image will my device brick ou the bootloader will present a "impossible to procede" screen?
Thank you for the help!

you can flash what ever you want in fastboot -
However - In terms of firmware, if you are trying to flash incorrect firmware then the verification check will fail and it will not flash
Just don't flash a new bootloader if you are worried about it - its not needed unless you are upgrading an android version and that version has an updated bootloader
So I am safe if I follow these steps:
Manually Update Android Nougat for Moto G5 (NPP25.137-33) via Recovery
First of all, Go to Settings –> About Phone –> Tap on Build Number 7 Times.
Go to Developer Options –> Enable USB Debugging.
Save Stock Android Nougat rom for Moto G5 and save it in Internal storage.
Reboot Moto G5 Plus to Recovery Mode.
Select Apply Update from SD Card.
Select the Downloaded ZIP file from SD Card.
Wait until Installation process Completes.
Once the Installation completed. Reboot the Phone.
If my ROM is a wrong version, will the bootloader detect and deny instalation?

if you are talking about an official ota update then it will fail - you cannot update like this
An offical ota zip requires a non rooted device, unmodified system partition and stock recovery
you maybe able to download the ota update and save it (its in the cache partition)
then use flashfire app to install it
note if its a custom rom than recovery mode will allow you to flash any zip and will flash anything unless the updater script specifies a certain build.prop target eg phone model or other criteria that would stop it flashing if it was false
If you want to flash firmware you need the firmware image and flash it via fastboot

Hi folks ! i have read a lot but getting confused somehow. Can anyone tell me or guide how to root my HTC 10 on Nougat ?
Unlock bootloader
Flash latest TWRP
Flash latest SuperSU
Beware Unlocking bootloader resets phone
Make sure to Nandroid backup
Better would be to flash Magisk to obtain systemless MagiskSU. This will keep SafetyNet working which is needed for Apps like Android Pay and so on to run and work. On the other hand you can in addition install some miss without even modifying system which would enable you to just flash stick recovery and install official OTAs as soon as they hit.

Bootloader needs to be unlocked. TWRP is compatible to Nougat - see TWRP thread. Latest Magisk can be found in the Magisk forum. Yes you can flash mods and install root Apps if you flash Magisk as it will flash MagiskSU as well.
All can be found in the respective threads, named above.

Detail your steps, please. Exactly what TWRP version are you trying to flash, and where did you get the TWRP (link to it)? Did you check the MD5 hash of the TWRP you flashed? https://twrp.me/, besides supplying all the official versions of TWRP for the HTC 10 "pme", also gives a link to the MD5 hash of each version in small print on the Download page for the version you choose "md5 for twrp-3.2.1-2-pme.img".
How are you trying to get into TWRP once you flash it? On the 10, after holding the Volume Down and Power buttons to boot into Download mode, choose "reboot to bootloader", then from the bootloader choose "boot to recovery mode".
I haven't been on Nougat since 8.0 came out so I can't personally test the latest TWRP with it, but if there's any problem with the latest versions with Nougat I'm sure it'd be mentioned in the TWRP thread here in the HTC 10 Development section. Have you asked about this issue there?

Hey, thanks for the quick reply mate.
Bootloader unlocked through the HTCDev site instructions. DL mode shows device unlocked, software modified, and S-On. SD Card is inserted. Fastboot in download mode to flash every .img listed on twrp and all .img files from the unofficial list. Didn't check the MD5's, thought it was pretty unlikely that all failed, but I'll try that when I'm out of work. Attempting to flash from Download Mode, using "fastboot flash recovery twrp***.img", *** changing per version. From bootloader mode, when I choose "Boot to recovery mode", I get the HTC logo + red disclaimer, then a reboot, more HTC logo + red disclaimer, then back into bootloader mode. Google searches have suggested using unofficial TWRP 3.0.3-6 or 3.0.3-9, but these files are nowhere to be found anymore. DL links here on xda seem to have been removed. 3.0.3-10 and -11 produce the same error as all other .img files. I've tried this on a machine at home and a machine at my job, so that's two different networks as well.
As a secondary, I've also tried "fastboot erase recovery" a few times before flashing TWRP images, same result.
Edit (2/3/18 @ 16:01): Verified the MD5 hashes, everything has downloaded correctly. Even if anyone has a copy of the 3.0.3-6 or -9 .img files, I'd be willing to try those out too.

Any news mate? Being able to root this phone was a major condition when I bought it.
Hi.
I rooted my M2 10 Wifi (A01W) with Kingroot and apparently now it's unroot (Magisk Manager said that). Even I made a factory reset.
I have the _B007 version and when I try to upgrade via OTA to _B008, it always fail and show "Failed to check the update files. Please download the package again".
I've working with ADB, Fastboot... and I could see that it's unroot, but the Bootloader is Unlock and I can't Relock it. Maybe it's the reason because the OTA doesn't work.
So I got a fastboot code with DC-UNLOCKER and tried to relock (fastboot oem relock CODE) and the answer was:
FAILED (Remote: root type is risk)
If I execute "fastboot oem check-rootinfo":
old_stat: RISK
now_stat: RISK
change_time: xxxxxxxxx
Apparently, the Recovery is stock, with EMUI logo showing 3 options:
Reboot, Wipedata/factory reset and Wipe chache partition
I made the factory reset that way.
Any idea? Thanks.

Well, I've read that flashing a system.img extracted from the UPDATE.APP I would can restore the Stock ROM... but I don't find a complete Stock ROM for Mediapad M2 10 Wifi (A01W).
I found the OTA in Romfirmware or Fordroid (sorry, I'm new user and I can not post external links). With this I can flash BOOT.img and RECOVERY.img, but the problem persist.
Does someone has any idea... or where can I get the complete Stock ROM?
Thanks!!!

Just one more doubt.
The firmaware I need (as read on the tablet) is M2-A01w...B008 for West Europe
The firmware that the page shows is M2-A01w...B008CUSTC100D001
Do you know what CUSTC100D001 mean? Could I used it without problems?

Glad it helped and yes it is not so expensive regarding the fact that there are all sorts of official firmware (mostly leaked ones) available for a lot of manufacturers.
The CUST reference at the end if the firmware version can be found in settings > about the tablet in the very last line. Mine is in German, So translated this line would state something like adapted/customized version. D001 is definitely Western Europe,this should be fine.
If not familiar how to install it google or search the forum for dload method. It will tell you what to do.

I've done:
1. Get the correct firmware (version ...B007) and extract the RECOVERY.IMG and UPDATE.APP.
2. Flash the RECOVERY with Fastboot and install the UPDATE with the "dload" in the SD.
3. Reboot in RECOVERY MODE, wipe all and restore factory settings.
4. Then, the tablet was updated via OTA to the ...B008 version.
Then, positive:
1. The OTA works fine.
2. I was abble to install the Nextlix App and the HBO Spain App plays videos. Both didn't work before.
3. If I execute "fastboot oem check-rootinfo":
old_stat: RISK
now_stat: SAFE
Then, negative:
1. I can't relock the Bootloader yet. When I try to relock (fastboot oem relock CODE) and the answer was again: FAILED (Remote: root type is risk)
Well, for normal use that's enough, but... THE RELOCK is becoming personal!!!
