Hi, I'll try to explain what happened and what you have to do.
The firmware that you have flashed (B512), corresponds to devices with region: hw / spcseas (Asia) And your phone came out of the factory with the version: hw / meafnaf (Middle East). This way you will not be able to update via ota or via DLOAD.
When installing a different region on another is in error. obtaining compilation C900B514 / C900B522 / C900B560. Then this way it is not possible to update.
There are four regions:
hw/spcseas (Asia C636B512)
hw/meafnaf (Middle East C185B514 / C185B560)
hw/cn (China C01B351 )
hw/eu (European C432-B522 /C432-B560/C432-B571)
check your current region. dial *#*#2846579#*#* then tap on network information>vendor country info.
What you have to do is a rolback with the c900b500 transition package (Works for any region) and then install the corresponding version with each region
I have a mexican telcel model MHA-L09C69B110, and throug huawei firmware finder, found OTA MHA-L09BC69B110, but due the fact that other two carriers AT&T and Movistar have Mexican versions, have a doubt to install it. How to be sure that it belongs to Telcel?
1. How to find Vendor Info
Go into dialer (only stock works)
Enter *#*#2846579#*#*
Go to 3. Network Information Query
Choose 4. Vendor Country Info
2. How to analyze ROM.
Go to FF site with your model
http://hwmt.ru/hwmtsite/firmware-database/?firmware_model=Mha-l09bc69&firmware_page=0
Choose filelist and notice what text written in vendorInfo.
In common case, there are three files:
update.zip
update_data_(full_)public.zip
update_(full_)[your vendorInfo].zip
Example: update_telcel_mx.zip
If 1 and 2 are same, so you can install this OTA
Question
I have a firmware that doesn't appear anywhere
IUSACELL, MX MH09-L09C212 EMUI 5.0 Really Alcatel Mexico
And software finder doesn't find it, is this something normal that firmware's are not register?
Thank you

Your only option is change to L29C636 firmware (free), L09C432 (paying) or keep the current firmware with AT&TMX.

Yes. It is normal.
FF does not know path to ROM with your localization. Probably, Huawei flashed stock firmware in factory and did not post it on HiCloud.
All firmware are in Huawei's HiCould. FF scans some parameters and checks if update exists on exact link.
You can help if you will receive notification of next update and find link to it (you need find from what link phone will download update)

Even when I did extract the files with HuaweiUpdateExtractor appeared the file VERSION.mbn, opened with notepad, can be read MHA-L09C69B110, , and made the folder dload in external SDcard and paste the UPDATE.APP file, message told no valid version for this phone, etc.
So I desisted to update until be sure about. I had a doubt: does UPDATE.APP the only file to paste inside dload folder? Other files seem to have information so neccesary for update. But I understood that the only file to be paste does UPDATE.APP, so we need some help at this point

Most of ROMs are with tag online_update.
So, you can't install them via dload-method, sdcard-method and other offline methods. Only online, only via system update.
Using system update to MHA-L09BC69B110 give me a file bigger than 8 gb and fail

Your only option is to upgrade the current model to C432 or C636. Telcel,ATT & Movistar in Mexico will take a lot of time to bring an update to the Mate 9. You can flash the C636 for free and with this your device will have more updates by OTA or FullPackage. For the C432 you will need to pay an online method to do this but this will change your Mate 9 to Europe version.
I own currently an MHA-L09 from ATT-MX with C432 on it.

Hey Guys,
I have the Stock Rom GEM-701L...C199B003 .
Could you tell me the difference between it and C100B003?,
and Can I OTA update to C100B008?
Thanks in advance
C is the region code, but we always install different region roms, as huawei offers son many C variants of their device, they cannot product a update for every variant of every model.
In fact on the X2, it is very often that we cross flashing different C roms, and even different model roms (for example, if you want android 6 on your 701L with official rom, you'll have ton install a 702L rom). All those crossflashs work very well.
Not for example that the app firmware finder enable to look for 701L roms instead of 701LC199.
If you want, I can find you a C code chart, to know which C is for wich region (if I remember well, C199 is marked "factory", so not regional in fact).
For you I advice on of these choices :
- Incremental dload update to B005, then B008
- If you install TWRP recovery, you can install directly with it the flashable 701L B008 stock rom by ajsmsg78.
- If you want official android 6, direct dload install of 702L B205
- TWRP recovery install of a custom rom, for much features and less bloatwares ( simply international B205, or kangVIP v3 slim B212)

Many Thanks for these informations
:good: :good: :good:
But before the links,
I think I'm getting too old for rooting, Unlockin Bootloader and these things
I used to do everything with my previous phones
But now I just want to update peacefully my phone to the last 701L B008
So I'm only asking if it would work if I only update from B003 to B008 directly or Incrementally
Or even Flash the B008 full stock rom via stock recovery (the one with only update, wipedata, wipecache)
And would it work If I updated with a different region File?
Again ... Thanks and best regards.
For simple way, follow post #1 here:
https://forum.xda-developers.com/mediapad-x2/general/ota-b008-701l-sept-7th-2017-t3674628
, and first install 701L B005, then 701L B008 (links are in this post) . Full B008 rom does not exist.
But there is an easier way, that gives you moreover android 6 and EMUI 4 (far better!) , just install by official dload method, 702LB205 full rom, directly on your 701L device , works like a charm. See:

Of course I will do the Android 6 thing.
I'm downloading the rom right now.
As I understand it from your links , It's too simple.
Just copy dload Folder & auto_upgrade.cfg file into internal memory then restart or local update ..... Right?
But sorry, I need confirmation from you that everything would be ok because you know I can't do a nandroid backup and I don't want a brick phone.
And thanks alot, you've been very helpful and so patient with me.

1) download the file "GEM-702LC209B205.zip"
2) rename it "update.zip"
3) put it in a "dload" folder at the root of your external SD card, or at the root of your internal storage
5) do a EMUI local update (I recommend that way) , or reboot the X2 (to be sure to launch update at start, turn off the X2, then force the update: power on your X2 with the three buttons pushed until screen shows something)
702LB205 rom has been installed on 701L device with B003 rom before with no issues at all, everything works fine (including 701L extra 4G bands), that's just that your device will now show 702L in "about phone" !

Yeah, But it is a good difference and I like it .
There is only a little brightness or color hesitation in the home screen just after closing a game or restarting. Also Colors in some HD games at some point become a little bit pale (although with better performance).
but it is not that annoying.
And some settings go back to default after a while like Disabling the default Keyboard.
But other than that everything look great.

hi
Need to be rooted the 701l
let me know if it need to be rooted?
Root it if you need yourself to use a app for tooted device only.
If you don't see the need to be rooted, that's mean you don't have to root.
it works für me. (inflated the zip into dload-Folder on SD-Card and run the Huawei Update-Program by pressing Power on and simultaneously Vol+ and Vol-). Now I have a GEM702L.
Is there the boot and recovery area updated, too by flashing this rom ?
I flashed it, because I had (and still have) an issue: I cannot enter the fastboot-mode. see here
Hello Djiban,
I would like to follow your process.
But all GEM-702LC209B205.zip files that i that I find incl. the ones in your 2 links (one link is dead) are no valid ZIP-Files (they could not be unpacked) and they also fail while doing the update.
It seems they are all the same corrupted file with the exact same size of 1.402.994.688 Bytes.
Do you know an actuall and valid file?
Thank you in advance,
Wonko
Greeting, folks. Yesterday a got a brand new Mate 9 with a carrier in Colombia (South America). SInce I did some research I found that my current version (MHA-L09C25B16) is a custom ROM (I don't really know if the version is for the country or the carrier). I was wondering some things.
1. I searched on the web and used FF but could not find a ROM compatible with my current version
2. I'd like to know if there is some chance of updating without having to unlock the bootloader and install a ROM by flashing the device.
3. I need some guide on how to change my software to an European version so I can have the latest updates always.
Thanks in advance.

Hmmm.
1. I found only MHA-L09C25B106 OTA in FF. It is old version.
2. No chance. In case of rebranding you have to unlock bootloader, cause need change oeminfo.
3. There is guide but there is one problem also.
You have MHA-L09 that is one-sim model.
Oeminfo mha-l09c432 is not original, it was created from dual-sim model. Even if you're rebranded to this you will get gui elements of second sim.
Guide to rebrand: https://forum.xda-developers.com/mate-9/how-to/guide-mate-9-flash-update-package-t3593108
Additional problem is that you can't back to C25 region. MHA-L09C25B106 is OTA rom, not Full-ota. It can't be installed over other regions.
P.s. it would be better to sell this model and get dual-sim L29 model. Even if you're not using second sim, you are able to use sdcard in second slot.
Well...I went a little deeper in my "search" and found something (I think).
Officially there's no C25 Software model... It´s a Custom ROM for the carrier Claro (CUST C25D005). A custom, I SUPPOSE, was created from C605 Official Software (which happens to be, Official Colombia Model...Other Mate 9 sold unlocked in Colombia are MHA-L09C605).
So...my guess is... Even if the version is the C25 custom...could I install a C605 ROM?
And...in case I could do it...how would I do it?
Thanks a lot 5[Strogino]

I never faced with this customization and never read that anyone did it.
There are some ROMs for L09C605, so you can go to this region, but imho you need L09C605 oeminfo.
Huawei uses localization model of ROMs. When flashing phone looks like generic model (M300). Then script finds metadata in oeminfo to generate product and vendor partitions. If metadata is not match, you will get wrong info in "About phone".
Maybe I can be wrong and in your case there is simple process of inherited region. But who knows? As I said, there is no way to return to stock state.

Well then. Whenever the OREO update is released for the C605 region I would definitely do it. Would you please indicate me how to change the OEM info file? And how do I update when I have the .zip file? Do not know much about these processes.
I was wondering too... Why some updates contain three zip files?

To change oeminfo, you can place L09C605 oeminfo into directory for oeminfos
Or you can change bin file in TWRP backup and restore it.
