I know this is an old thread, but I only recently discovered that you cannot officially downgrade your firmware on the G7.
This was Huawei's response when asked why we can't downgrade our firmware:
Hi. We don't recommend downgrading as it will affect the phone’s performance and may lead to fundamental performance problem.

Why this could lead to performance problems if it's a forced upgrade, I have no idea, and I also do not believe that.
I was able to upgrade/downgrade my P6 so easily, without any issues whatsoever, so I find their response very hard to believe.

Any chance to upgrade from b133 chinese room to marshmello Global room without root?

Im pretty new with Hauwei and i cant understand how to put a Global rom with Hebrew on my Ascend mate 7,
it is now running a chinese room model b133 and every time im trying to update it throw dload and at the update software it failed.
im working on it for 4 hours and i didnt find a way to do it without rooting the device ( witch i dont want to due a low experience at rooting devices and im afraid of brick.)
Thanks
Technically you don't need root. But you need an unlocked bootloader. Of the upgrade is for the same region it should work. Make sure it is

I don't have an answer for your question, however I have a suggestion. Why not consider upgrading to Chinese LP and then Chinese MM, unlock bootloader, flash TWRP recovery and then Flash Kang VIP B555a.

Im really trying to learn but guys im pretty new at that staff..
Ok so the main idea is that i have to open the bootloader and to flash TWRP recovery just to get rid of the chinese rom? No any other options?

Well, I think you'll need a unlocked bootloader if you want to try out a rom for a different region.
You can try upgrading to an international LP rom via local update. I am not sure if that will work though because I haven't tried that ever. Local update is unlikely to break your phone even if the update fails.

Can I repair my cell phone?

Greetings to the people of the forum I am new so I apologize if I commit any lack
My case is so try to update my Huawei CHC-u03 to lollipop and marshmellow with the method of honor 4c
all good up to lollipop and a minor update, then when installing marshmellow (all this from sd with the method from the settings of the mobile) the phone is in bootlog and only says honor
I have not been able to revive it with any firmware from the 3 button method, I have tested with firmware 4.4, 5.1.1 and nothing the phone is still in bootlog
when forcing install from sd only says software install failed
* my biggest mistake was that I do not realize that the mobile is not root and has the bootloader blocked without possibility of unlocking because it has imei and serial number changed
Then can I fix it? or should I call it dead?
sorry i used google translate
When you say with the Honor method do you mean you flashed another phone's ROM on your device?

You should never at any case use another phone's ROM on your device as it will cause lot of problems including hard bricking

Android devices are not like PCs. You can't just install whatever operating system you want. Android is built for the specific hardware and device model number it is installed on, it is not built to work on other devices. It typically destroys a device when you flash a stock firmware or ROM from a different model number.
Your only hope is to flash your ORIGINAL stock firmware for your specific model number.

Old firmware?

Hi all. Today I purchased an Honor 6x. I am in the UK. The phone has been on all day and I have been tapping the update button like crazy. It seems that I am stuck on EMUI 4.1.3 and Android Marshmallow. Should there be a Nougat update in the UK for this phone? Thanks in advance

Ah thanks both. I've just had a look at that site and firmware finder. As there doesn't seem to be an OTA update heading my way I might give firmware finder a bash. Many thanks.

No, it doesn't work at 100%, often users detect problems of various types after using FF here on XDA, this because it can download even packages that not always match your phone variant...

Updates should be already came out if I'm not wrong, try to force the update by clicking on system uodaye -> 3 dots on the upper right corner -> down latest update. If nothing is found, try to write to Huawei and ask about the most recent update for your build
I have sent Huawei an email requesting information with regards to an update. Obviously I'll get no reply being the weekend so I have been sat here looking at firmware finder. So close to using it. From what I understand it won't void the warranty of the phone if I update using firmware finder. What if the update doesn't work can I revert back to the original version. What if the update bricks the phone? Is that easy to fix?
TIA

The rollback packages are available only for a limited amount of models at the moment (and i think forever, if Huawei wouldn't upload other packages as they've decided to do) so it could be a pain without a proper TWRP backup. For unbricking, there are some methods for doing that and it could be easy like it couldn't be, it just depends by the problem that could occur.
Ah thanks RedSkull. I might try and kerb my eagerness and see if I get a response from Huawei. This week's a bit busy so probably not the time to try anything risky.

Help me.my build number is b361 and I want to update to b380

Anyone has L19C636B380/360 full firmware package?

I had Nougat(L19C636B360) when I bought my phone. The box had model "AL-10" written on it although the firmware was of L-19. Anyways, an OTA update arrived, I clicked on update and it got bricked. I had never unlocked the bootloader, rooted or anything. After a lot of trial and error, I successfully got my phone working by flashing MM 6.0 - FRD-L19C900B131 through 'dload' method. But this firmware is buggy as hell. My phone's laggy, crashes constantly, the photos are worse etc.
A found a couple of stock firmware packages(L19C636B360) on the forum but they come with two separate files(update.zip and updata_data_full_hw_specxx.zip) and my phone doesn't support them(Installation fail). Also they are of only 2-2.5GB, whereas the one I successfully flashed is 3.3GB
Note : I have unlocked the bootloader now
And you are developer?
Wrong forum to post buddy.

A12 -> A10

Hello!
I lost my warp charge with the new H41 update so with that gone my phone is totally useless.
I want to do a rollback and from what I ve heard/experienced A10 was the best OS.
Can I roll back from A12 to A10?
If the answer is no, how would I go to A12 to A11 and then A10?
Thank you in advance

Hi, yes it is possible. You have to download the firmware for your android 10 device and I also have to warn you that you will lose all the data on your phone and I think you will also have to have an unlocked bootloader to downgrade but I am not sure.
