Hello everyone,

After a few tries, I have found out how to boot into our phone's stock recovery. We are now one step closer to root and flashing new ROMs! :D I know all of us can't wait for that.

Edit (September 6): ROOT AND UNLOCKED BOOTLOADER ACHIEVED! Check out the thread here. If you need help, don't be afraid to post in that thread! We'll get to you ASAP. :)

1) Turn off the phone.
2) Hold the power button and volume +.
3) Once the Huawei logo pops up, let go of the power button but not the volume + button.
4) The recovery will pop up, and you can let go of the volume button.

It'll look like this:

Scoob I really appreciate what you and Modding.My.Mind have done today.
We aren't there yet, but we're so much closer to root because of you guys.
Thanks alot.

If I had this device in my hand I could tackle it personally. Unfortunately, that is not the case, but I hope you guys see root soon. Now that you guys/gals know about this feature on your device it is just a matter of signing the update.zip properly which I sent to @ScoobSTi a few days back. The updater-script is written so that it will work in a stock recovery but without an acceptable signature the stock recovery will sadly deny it.

Go ahead man, no problem. It's made public on my dev host account. I recommend you make a notice in bold red in case you get that one guy lol. A disclaimer of some sort for development purposes.

Thanks! I'll just attach it here haha.

For those that don't know: attached is the flashable ZIP file that Modding made for us. If successful it will grant us root permissions, but at the moment it doesn't work, because it is not signed correctly. If anyone knows anything about signing, please try and work your magic! :good:

Man, hopefully we will see root very soon.

I almost ditched the phone for a Galaxy S5.

:(

Glad I didn't.

I'd much rather see root versus Kit Kat update.

Following is a little bit more info:

Confirmed this device (MT2-L03) bootloader is locked.

I press and hold "volume down" and "power" keys for more than 10 seconds, I got into the fastboot screen, it displayed that bootloader is LOCKED.

http://www.emui.com/plugin.php?id=unlock&mod=detail
http://www.emui.com/plugin.php?id=unlock&mod=step

Above is in chinese, google translate should give OK to understand like:
https://translate.google.com/transl...//www.emui.com/plugin.php?id=unlock&sandbox=1

https://translate.google.com/transl....com/plugin.php?id=unlock&mod=step&edit-text=


And get-bootinfo show same:

D:\Android\android-sdk\platform-tools>fastboot oem get-bootinfo
...
(bootloader) *******************************************

(bootloader) Bootloader Lock State: LOCKED

(bootloader) System State: need to verify
(bootloader) Boot image need to be verified
(bootloader) Recovery image need to be verified
(bootloader) Bootloader Version: 001.001.000

(bootloader) *******************************************

OKAY [ 0.058s]
finished. total time: 0.061s

P.S., I have sent email to their support ask if they have any plan to add "MT2-L03" device to their request page. Let's wait and see.

I'm curious, but could you try:
Code: 
fastboot oem unlock

May or may not work, so it's an idea. Not all devices can use this directly without taking other necessary steps.

Hi Modding.MyMind, First want to thank you give us MATE2 forum your help, and that su binary flash zip. Unfortunately, I tried a tools called Auto_Sign, and also use my own key to sign, both zip cause "Installation Aborted".

That's why I post above locked bootloader info, but still due to my limited knowledge of Android, I am not sure the relationship between the root and locked boot loader.

I read some articles like this:
http://xdaforums.com/wiki/Bootloader
http://www.xda-developers.com/tag/bootloader/

Those give me mixed info, I even see some phone can root first, then flash a unlocked bootloader.

OK, back to topic, following is the output:
Code: 
D:\Android\android-sdk\platform-tools>fastboot oem unlock
...
FAILED (remote: Please input key)
finished. total time: 0.009s

And even tried a dummy unlocked code (this should be 16 digit as the huawei website example says):
Code: 
D:\Android\android-sdk\platform-tools>fastboot oem unlock 1234567812345678
...
(bootloader)  Unlocking ...

OKAY [  0.018s]
finished. total time: 0.021s
But, no, its not working, the phone display "Invalid Key" and rebooted.

P.S., I am Chinese and own a different HuaWei phone before. The official way is to use their website to request the unlock code, Huawei will record your SN number, and give you correct key to unlock it. That's the reason I have sent email to them to see if they can support this MT2-L03 in their request page.

Actually I just own this phone a few days, and starting reading the forum post, I think "ScoobSTi" actually tried the unlock before with similar result.
Anyway please let me know if you want me to test anything else.

Thanks.

unlocking that bootloader could possibly make some of the previous root methods several people have tried actually successful.

Oh this is getting interesting. We seem so close.

For some devices unlocking the bootloader would allow installing root similiar to what I shared. For most, it isn't enough. For the majority out there it is likely that a custom recovery be available to successfully gain root (which in turn would require an unlocked bootloader). Each device is different in these cases. For my current device, an unlocked bootloader is required so that a custom recovery may be allowed to overwrite the stock recovery.

Though, I will say, that by having an unlocked bootloader, the possibilities will most surely increase.

This is a bit off topic here, but TWRP is built to root devices if one by chance is developed and built properly for the "given" device. Saves the hassle of having to make flashable zips lol.

I actually need to rebuild TWRP for my device :p. Just got to sync omnirom after accidently screwing up my linux system this past weekend.

Thanks for trying! We may finally be getting closer now. :D I'm seriously missing a lot of the root tweaks I had on my old phone.

Teeny-tiny update.

It seems Huawei has updated the Emui website, most likely because of the Mate7. It is now both in English and Chinese.

The bootloader unlocking website has also been updated in the same fashion. The Mate2 now shows up, but unfortunately it's the MT2-C00 version, not our MT2-L03/5. Hopefully Xordos's email will help!
