Well, unfortunately unlocking the bootloader is a no go option... By the way, when You say "flash the firmware" do You mean use the update folder (up to now I found only this method all around), or is there a specific tool to do it? If there is a tool, I'll look for it.
[Ascend Mate 7 General] mutahharbashir:
Without unlocked bootloader, don't expect debranding.

I suggest upgrading to lollipop and then do debrand using this guide.

[Ascend Mate 7 General] birobiro:
While suggesting to upgrade to lollipop, that would be enough for me, do you mean that I can install an unbranded KK (like 137sp03) without troubles, keeping the bootloader locked? Then, if I need to do it, I will have to use that guide? Please, I'm only asking if it is possible to change from 'branded' kitkat to unbranded one, and possibly increase version. Take care that up to now I haven't found a guide to unbrand the mate 7 still at KK version. Of course, if the answer will be "you must unlock" if you want to unbrand, I will do it.. (at my risk, this is the company phone...)

With locked bootloader i have not tested /tried.

Maybe [MENTION=4190256]chudy_85[/MENTION] can help.

I have debranded using the guide i have posted.

If you from Europe you can unbranded flashing b137sp03 this it's firmware unbranded you can download form Huawei it web
[Ascend Mate 7 General] birobiro:
[MENTION=4190256]chudy_85[/MENTION] better put the dload directory on SD and use the update from recovery, or it can be started from local update? Thanks.

[MENTION=7380201]mutahharbashir[/MENTION] I managed to upgrade my mate until b560. Unfortunately, using the link you provided to download b571 full firmware, the install process fails at 5%. The network I found it is still Tim as provider and network it (italy). Do you have any hint?

Try flash b500 to downgrade and then flash b571 but you can't back to b560 because they change something in file to downgrade

Please i need help with urgency.

Long story short.

1) sold my mt7-l09, need to ship it

2) i have TWRP 2.8.7.0

3) i think i had lollipop

4) made factory reset. something went wrong, now it says "no os intalled" when i try to reboot to system

What i have done.

Downloaded B327 ( General Latin America - Colombia ) MT7-LO9 5.1.1 Full Firmware

Im going to try to install it but it says update.app. If i have no OS will it work? im i going to brick the phone?

Is it safer to try to intall a custom rom?

Im running against the clock over here.

Thanks

[Ascend Mate 7 General] chudy_85:
1. You must have ext sdcard

2. Create dload folder and put there update.app

3. Flash stock recovery for lollipop

4. Use your key to flash firmware using standard method.

5. After this do it wipe in recovery
[Ascend Mate 7 General] birobiro:
Yes, I did, thank You... I will try as soon as I have a free evening.

[MENTION=4190256]chudy_85[/MENTION] [MENTION=7380201]mutahharbashir[/MENTION]... It looks really strange, as I've read that B571, as a pre-requisite, needs at least a previous version of MM, as B513, B522, B560. Ok, I'll try, hoping not to brick the phone.
[Ascend Mate 7 General] Esteban0506:
Hi all,

Hi everyone...

Im from Colombia and im currently in firmware MT7-L09C900B327. I want to upgrade to B570 but i dont see the specific rom for Latin America, only europe.

Having that in mind, i have a couple of questions:

1. What happen if i change the region and apply the B570 europe to my phone? someting wierd could happen?

2. If nothing happen, can i jump directly to 570 or i have to follow a specific path of ROMS to apply?

Thanx for the help.

David
[Ascend Mate 7 General] mutahharbashir:
Rollback method has been already shared somewhere on page 75.

[Ascend Mate 7 General] Velocesuper:
Hello :)

How to install the rom C432B560 or C432B571 with TWRP ? Please.

When I use this :

1) Transfer the Update.app package to "dload" folder inside the external microSD card.

2) Open the dialer and enter *#*#2846579#*#* to open the project menu.

3) Go to Software upgrade > SD Card Upgrade and confirm the installation.

TWRP launches, but not the update :o

Edit : Solution is : "Power + vol- + vol+" to force the update.
[Ascend Mate 7 General] mutahharbashir:
You must install stock recovery only then software upgrade works.

You can try this, copy firmware zip to sd card,

Then in twrp press flash and select the zip you have copied, swipe to install. Done
[Ascend Mate 7 General] Velocesuper:
Thank you for the tip on TWRP :)

But this solution works perfectly : shut down the phone and after press the buttons "Power + vol- + vol+" to force the update in the folder : "dload"

Hi,

I have a mate7 gold (32gb 2 sim) and I want to update to lollipop/marshmallow/nougat? but I am not sure how to start.

I have a MT7-TL10 V100R001C00B124. I havent been able to find much useful on that version and so I dont know if I should go to another prior to the update.

In the about section -> Certification it says Serbia,

Region:

Vendor: hw

Country: eu

Any help to do this without killing my phone would be greatly appreciated!

Thanks!
[Ascend Mate 7 General] mutahharbashir:
Nougat will not be released for this phone

Your phone is European.

From 1st page.

1. Download European lollipop firmware for TL10 and install

3. Download European marshmallow firmware for TL10 and install it

Done

Really weird problem after using the B571 TWRP backup for L09, some system applications are not installed properly and instead show up as Android heads. I can't run the applications at all since pressing on them does nothing.

I want to go back to complete stock and I had to use the TWRP backup because using stock recovery with update.app didn't work (it gets stuck on 5%, it still gets stuck on 5% even after using TWRP backup).
[Ascend Mate 7 General] chudy_85:
Yes because twrp 3 don't correct restore app from cust to data partition. Check what region you have!!! If you don't have restore oeminfo and then flash stock recovery and b571 update.app and do it wipe data/system in stock recovery
[Ascend Mate 7 General] MiniDemonic:
It's not the region, I'm in EU and I used the EU downloads.

I extracted cust, system, boot and recovery from update.app and flashed them using fastboot. The apps that weren't working before works correctly now. Update.app still won't get past 5% when forcing an update on stock recovery but it's working correctly now so I don't see a need to do it anymore.

After that, when I try to update complete eu firmware using 3 button method, it still fails .

please where I am doing wrong ?

Either you must go back to Marshmallow and then change region.

Or restore B571 twrp backup of European version.

Hello my friend

I recently stuck on KitKat 4.4.2 emui 3.0

After I downgraded my device from android 6.0.1

I'm now on MT7-TL10 V100R001C00B130 build number .

When I was on lollipop I have a back up stock recovery , as I flashed it back to get ota update and downgrade version of my phone .

I used twrp to flash the stock and also tried flashify too , which those worked when I'm on lollipop version .

And now i couldn't flash stock recovery on this KitKat ,

I tried extracting the stock recovery image from its original firmware and flashed but it not working

.

I tried a couple recovery from Russian site

And it still not working

.

And now I still on 4.4.2 , can't upgrade to higher version due to crazy stock recovery

Im sure i installed the correct version of recovery

It is b130 :(

The error in bootloader was

Fuc error (boot recovery )

Can anyone here help me ??
[Ascend Mate 7 General] cege987:
Did you try to flash the stock recovery using ADB?
[Ascend Mate 7 General] Jackson EH:
No, I didnt . I dont have a computer right now

But I'm sure

I flashed the right recovery

And it said

Func error 10 (boot_recovery)

Error 2

I'm sure it said I flashed the wrong recovery

These are the recovery
[Ascend Mate 7 General] Jackson EH:

[Ascend Mate 7 General] cege987:
Sorry buddy, not sure what else could be the problem. Perhaps try downgrade TWRP to 2.8 if you are on 3.0 and try reflash stock recovery. I've always used ADB to flash recoveries and I've never had any problems
[Ascend Mate 7 General] mutahharbashir:
All of them are wrong,

You need kitkat version recovery

You only have lollipop and marshmallow versions

I'll try flash using adb

Hi guys, I need your help.

I have an MT7-L09 Europe with Android 4.4.2 - B137 with Unlocked Bootloader, CWM recovery v6.0.5.0 and Root permissions.

I would like to be able to upgrade to android 6.0 without losing all the apps and their settings, I tried it directly through OTA but after downloading the b145 update the phone reboots and enters the CWM without updating.

Is it possible to upgrade without a wipe?

What is the right procedure I must follow to not miss all apps and settings?

Do I need to flash stock recovery?

Thanks
[Ascend Mate 7 General] cege987:
You can upgrade via OTA, but you must first restore stock recovery. You cannot do OTA with CWM still installed. That is why after reboot it goes into CWM without updating.
[Ascend Mate 7 General] teosc:
Thanks a lot for the quick answer.

If I extract from stock update package "C432B571 Full OTA" and flash recovery.img in fastboot are there incompatibilities with b137?

So I would do so:

1. Extract from stock update package "C432B571 Full OTA" and flash recovery.img in fastboot

2. Make all OTA updates up to Android 6.0

3. Reinstall CWM

4. Flash supersu

- It's correct?

- So I keep the bootloader unlocked, all the applications and their settings?

Many thanks
[Ascend Mate 7 General] chudy_85:
Don't do it because you be have big problem!!! You must download stock b137 and extract stock recovery and flash using cmd or download this program and flash recovery

https://mega.nz/#!BgJUSCrL!qrfFIbnJ8YjWcG0LYw6x7iZWEjRSDkylJUyWSGKKyxM

Cheers
[Ascend Mate 7 General] cege987:
No, you can only flash a stock recovery that is the same android version you are on. B571 is marshmallow and you are KK. So extract from B137 and flash that.

The rest of your steps are ok. You will keep all your settings, but make backup just in case.
[Ascend Mate 7 General] teosc:
First of all thank you very much for the help.

1. I downloaded "recovery mate7 mobopx v2.1" and flashed stock recovery 4.4 kitkat

2. From the default updater in settings I launched the update from b137 to b145

When the download is over, the phone restarts for installation, enters to the stock recovery and after a while returns the message "restore failed".

I restarted and the phone was reset to factory, with always on board the build b137 !!!

(Fortunately I had a nandroid backup)

What am I doing wrong?

Is there a system to go directly to the B571 without losing all the apps and settings?
[Ascend Mate 7 General] stanlawren:
B571 is an incremental update and can't be installed directly except you are already on B560. To install from any other version, you have to get to B560 and then install B571 from there.

Also since you are on kitkat, i'll recommend getting to B511 or 522 and then 560 and finally 571

Your version>B511/522>560>571
[Ascend Mate 7 General] teosc:
The problem is that any use method makes me a factory reset!

I did this:

1. Full unroot

2. Flash stock recovery for KK 4.4

3. Update from default please get updater b137 -> b145

Result = fake update then enters recovery, Factory reset -> Reset Failed

Cell phone restored to factory condition with still on b137!

I also did this:

1. Full unroot

2. Flash stock recovery for KK 4.4

3. Manual Update with OTA Incremental b137 -> b308 (with zip file)

Result = Update is done but at the end I always get a factory reset (this time without the reset failed message)

I do not want to get a factory reset but simply an incremental update

Where am I wrong? :confused:

Yet I did not flash the full firmware.
[Ascend Mate 7 General] stanlawren:
If you have been able to get to B308 then you are on the right track and you should be on 5.1 lollipop now.

Next step is to upgrade from B308 to B522 and from B522 to B560

And finally install the incremental B571 update.

BTW what's your phones Region? EU/Middle East/Africa?

If EU, then you can go all the way to B571.

If Middle East/Africa, you may have to go from B308>B511>B560 (final stop for Middle East/Africa variants)

To continue to B571 you need to change your oem info to EU but that will be a story for another day.
[Ascend Mate 7 General] teosc:
The problem is not the upgrades, I can also safely install the b522 full firmware, without a problem.

The problem is that after each OTA incremental update (b137-> b145 or b137-> b308) the phone makes me an unwanted automatic factory reset and I lose all apps and settings!
[Ascend Mate 7 General] stanlawren:
Some updates will factory reset your device (B522) will others won't.

If you can get to B522, then have no fear as that's the last update that will reset your phone.

B560 and B571 won't reset your device.

Also in most cases, B571 won't install on rooted devices.

So unroot before install.

Feel free to re-root after install
[Ascend Mate 7 General] teosc:
Okay, now it's all clear to me.

So there is no way to get to the B571 from b137 without getting automatic factory reset?
[Ascend Mate 7 General] stanlawren:
Am afraid so. B522 is confirmed to reset devices

Hi chudy_85,

I can confirm the 'Marshmallow to Lollipop' rollback package for 'Dual Card' /'Dual SIM' version of Mate 7 (TL10)

originally posted by albert-so758 (C900B500) works for my dual SIM Mate 7 TL10.

My Mate 7 is not rooted and its bootloader is still locked.

The downgrade pathway is therefore complete for both models of Mate 7 (L09, TL10).

Anybody with Mate 7 can now downgrade safely anytime from marshmallow to lollipop

and can proceed to downgrade further from lollipop to kitkat even with locked bootloaders/non-rooted phones.

Those who downgrade just have to back up data though because all data are erased after every step downgrade

(Ex. marshmallow to lollipop or from lollipop to kitkat). Phone will be like when it was bought new (almost empty

storage space and on default factory settings).
