Problem with stock Rom installation

Hello I need to send my phone for repairs, and so I've been trying to install the stock firmware. I've managed to downgrade all the way to b126, and I've received an OTA to b133SP01 but when i try to update it through the OTA it says there are no updates available. I have previously changed the stock Rom and recovery of this phone so I don't know if that's the issue.
Also can anyone tell me if under Settings -> about phone -> certification I can change the country it displays, on mine it says Serbia with a triangle on top, i think that has changed with a local update i did (downloaded from this forum), so does anyone know how to change this?

Do you currently have a stock Rom and recovery installed on your phone?

Well if you can't download it via Ota then download it from the Internet, then create a folder on your SD card called "dload". Copy the update there, turn off your phone and perform a forced upgrade by holding all three buttons down.

Yes, but i need it to be able to update OTA, i managed to go from b127 to b133 OTA but it stopped there. I will try to update to b609 localy and see if i can OTA from there.

If you need to send your phone for repairs, than any official version is good B126 B133 B609 or B852.
My phone says Serbia too under certificates, so I don't think that this is something to worry about.
Just make sure that your bootloader is locked (green) and hope that they'll accept it for repairs.

P9 eva-l19 (dual sim) and nougat update problems

I have tried several ways to install nougat to Huawei P9 dual sim, but it's almost impossible.
First i tried to install beta version, and it works ok but some apps are missing and keyboard is missing as well, it installs only google voice as a keyboard, so I restored it with Huawei rollback package.
Second, I tried debranding it so I can install some other version but I have similar issues. Here are my steps:
1. unlock bootloader
2. twrp recovery
3. root
4. change oem info and custom.bin, and this is where the problem starts.
After step number 4 the phone restarts and the letters during initial startup are red like system had been modified and after it goes to the part where it says "type password to decrypt storage". When I do that, it accepts the password (google) and says the phone storage is corrupted and I have to reset it, and then it resets the phone to default settings. After that I don't have root and no custom recovery. I tried this procedure several times and it's always the same. After the reset procedure, it installs some initial version (C900B136).
I finally gave up on that, and tried to get back to L19C432B161 but I have issues as well. First I had to restore my oem info and custom.bin so it accepts the C432 version, but after install some apps are gone and the theme manager is not working (it won't change icons or the wallpapers).
I tried using HiSuite to restore it back to stock but it won't accept the L19 version (only L09 and L29).
The tool I was using is SRK Tool Huawei 2.0, and I tried to follow procedure as described here on xda.
Any clues what I do wrong?

Well during this process I run into a bootloop and no recovery, so I unlock the bootloader, flash the stock recovery and then install stock firmware.
My phone is working now but it's not complete, some things are missing and not working properly so I am waiting some instructions what to do next. I really like Huawei phones but this firmware thing is a nightmare

Before you debrand, download the ROM of the cust you want to debrand to, place in dload folder on your sdcard. After step 4, your device will reset to factory, use sdcard ROM upload method and you will succesfully debrand your device. After that, if you debrand to L19C636B190 (for example), it will be OTA to L19C636B361.
My Al-10 was debranded and OTA successfully to L19C636B361 using this method.

Totally agree, once you are on nougat it really becomes hard to flash the firmware..till marshmallow, it was easier to control and flash the firmware..

Well this was the missing part
After i copied the L19C636B190 rom to dload folder on sd card it was successful.
Then I just connected it to HiSuite and it found the nougate update.
Thank you!

How did you get the OTA? I got it right after dload B190 (which I didn't update it yet) then I didn't have it anymore 5 mins later
UPDATE: Somehow got the OTA when my dload update to B361 failed

Resolved Missing apps

I've resolved the mistery of missing apps after update to 370 or 371. you need to change your drawer from settings
How to do:
Settings> Home Style> Drawer
tested by me all apps like calc and co will be appear

Thank you for the suggestion, but calc and so on (I cannot even know the list of missing apps) are nowhere to be found, even in Drawer view!
I just updated from L31C432B161 to 371.
Any ideas?
Thank you in advance,
Eric.

I don't know, this was my experience. after upgrade home was without some apps and i've resolved in that way.
According to me you have to downgrade to MM (there is a guide in the forum) and to upgrade with the OTA that was released for all, (so don't do it manually). good luck

Thanks! I did however proceed with the OTA update (not manually through SC card), but it seems that there are several versions of the update. One is 1.25GB and is missing some apps and gives bluetooth problems, another version is 1.99GB and seems to be OK!

Thank you, but I believe it is not the same: on the forum we have on one side the update.app and on the other side the data_full, and I believe maybe you haveone 1.9GB file with the full package? Maybe I am mistaken!

You Need the data_full

Yes I do, but I thought it would be cool if someone could upload the whole package.
I will try to install the data_full through dload on SD card.

I did not try in the end... I tried to dload B370 but it does not work because "incompatible version". I should try to OTA or dload B371 and then dload data_full, but I guess it will not work since it is for B370, not B371 and I am fed up with restoring all data on my phone for now!
I think I will way a bit until the official OTA comes out or someone else finds a solution. :/

I downgraded from B161 to B160 and was able to download B370 (1.9GB).
Downloading as I speak.

1.99 package are two separate files. when the program is downloading 1.99 it is downloading 2 files. so it's the same for you to flash only the data_full

Thank you @cmax24, I solved my problem by rolling back from B161 to B160 through dload, then MyCare found B370 (1.99GB) and... voilà! I was not able to take a look at the downloaded file(s), as I proceeded with the update immediately and the files were consequently deleted. :/
Thanks for your help!

BTV-W09C100B301 Guide How to update

Can anybody provide me with a tutorial how to flash B301 update which can be found via Firmware Finder for BTV-W09C100 version? I tried it once but came up with bricked tablet. Fortunately I was able to fix it after 2 days of research. That is the reason for step-by-step tutorial.
Last question: How is that even possible that B301 update can be only downloaded via Firmware Finder app and not via Settings->Update? Is it beta? Can anybody explain it to me? I am new to Huawei products.
Thanks guys

Hi!
B301 is an internal test build. I couldn't find a way to flash it properly, neither stock ways nor using unlocked bootloader and twrp (the update consists of two parts each with a different flashing method).
Better wait until official update appears.

To update to Nougat.
You have to first update to next higher version firmware than what you have and then go to Nougat. I read on some Italian forum that you should not update directly to Nougat. For example: if you have B009 then you have to select next higher version which is B010 and then update to nougat. But they advised against directly updating to nougat firmware from any version. For your model I don't know the exact firmware version but you can check in firmware finder.
(check your about page to find out the exact firmware version for your model)
How to use firmware finder?
Inside the firmware -> go to settings-> switch on the option -> add on proxy
Now go to your Wi-Fi settings
Tap and hold your Wi-Fi connection
You should get two options
Select "modify network"
Select - "manual" option
Then add the below in the respective fields
Proxy - > localhost
Port -> 8080
That's it. Save the settings. If you don't see the update here then go to firmware finder and select the firmware you want to download (select the next higher version than your existing firmware- > click on "send firmware to updater" . And then go back to updater in settings and check. you should see the OTA to update.
Now go to settings - > updater-> you should see update for your tablet there.
Once you are done with the update, again go to updater.
Now you should see the update for B301. This is more than 2 gb.
Just click on update and wait for it to finish. It will reboot twice. Wait for it to finish optimizing the system.
You have Android nougat now on your BTV-W09
Operating system is gorgeous. It is very similar to what I found on Huawei mate 8.
Nougat is beautiful on this tablet. Working excellently.
Some more steps here and many important posts in this thread -> https://forum.xda-developers.com/showpost.php?p=71955984&postcount=23 Check the link to Huawei website to get your rollback package if something goes wrong. Mostly it won't but if you don't like nougat then you can return to marshmallow with the help of rollback package using dload method.
Have fun updating. I would recommend updating to nougat without any hesitation.

This would work if the update was a full rom, but the test nougat build we have got consists of 2 separate zips, and data cannot be flashed after the core nougat zip (for example the updater app is missing from the core zip, it's part of the second data zip)

It will work just fine. I already updated using this method on my tablet and there are others too who did this successfully in the other thread.
After downloading in firmware finder you have an option to push it to updater. That will ensure both zip files are extracted and the update is sent to the updater as one file.
So I can confidently say that this is a working method and because of the steps that I mentioned in my previous post I was able to update my tablet. Otherwise my tablet would still be in marshmallow. But no, my tablet is updated to nougat now.
So I would suggest you and every one to please give a try. It will work. Please follow the steps correctly. Procedure is very smooth.

I just did it this morning with this method on my BTV-W09C128. I had happen what TaRsY mentioned. I no longer have updater app in settings anymore. Otherwise everything is running great. I'm hoping when the update becomes official in the US I can do a full update through recovery somehow

Thanks for the reply. I figured that out after asking you. I've already updated Nougat using this method.
I do not use bluetooth very much myself. So it not working is not much of an issue for me.
However, if you find a way to roll back please share for those of us that have made the jump.
Thank you.

Hello.
They are the two files to install with twrp since MM.
Or be in b370 and dload the first file (update.app).

No TWRP here, all stock - I'm trying to install using Firmware Finder + proxy which worked well for the two parts needed for B160 to B370. It seems there's an additional check going on now giving the authentication error after a successful download and verification.

OK,
I never found firmware finder server.
I always use twrp.
I am currently, in c432, I will change oeminfo and test it.

Well, I installed it. Interesting, android security June 5 and kernel version June 5, 2017.
I was c432b380.
Downgrade MM (c432b160), I use the toolkit to change oeminfo to c440 and firmware c440b132.
Then, bootloader code, installs TWRP for MM, install update.zip and file datafull.zip, REBOOT.
everything is OK. works correctly.:good:

Try to remove data of updater application and check again. This solution works for me

Tried clearing data for System Update, same problem Is that what you meant by updater application?
---------- Post added at 09:07 PM ---------- Previous post was at 08:31 PM ----------
If I put the phone into airplane mode the updater complains it has no internet access to authenticate, then fails as before; it really does look like there's another stage to this now.
I suppose I could try a factory reset and redo the FF+proxy approach but I don't think that'll work. Revert to B160 and try going straight to B380? Sounds like too much of a risk for me!
Without capturing the network traffic (or decompiling the updater app perhaps) to find out what it's up to it doesn't look like I'm going to get beyond B370 until someone somewhere else decides I can

Yes, this is that application what I mean. It's strange that system update download 4GB of data - I've got same problem and cleaning data and sending full package from Firmware Finder via proxy fixed problem, system update download just ~300mb.

Did you go from B370 to B380? It seems that the updater in B370, for me at least, is phoning home for 'authentication' and being denied. If it's working for you from B370 then I wonder what it's using for the check... IMEI, IP address location lookup... hmm. I might try again via a VPN server in Poland.

Not exactly, I upgrade from B371 to B381.

C440? I've not seen odd numbers for the UK/EE firmware.

This is not important - on Your screenshot is a bug with a big update file and this is why You have error with authentication

Good point, it's double the size showing during a download

Still fails when the size is shown correctly and using a Polish VPN

Same thing happens to me :/
I can't go from b370 to b380...
Anyone knows what is the difference between b370 and b380 and are there valuable reasons to keep trying to update our just stick with the b370?

If nothing else I believe it has a more recent Android security patch level. It looks like either the MM updater doesn't do the authentication check which is failing, or it does but b380 hasn't been cleared wherever that check looks. The only way I can see to check the first is to roll back to MM and try going straight to b380. Otherwise we're waiting on the authentication being given to b380.

I'm sure it's delicious, but will it install using FF+proxy or is a flash from custom recovery the only option? I'll give it a go later...

Yes just MM, bootloader, Chinese twrp.
Sorry, I do not know how to do otherwise.
Firmware finder server I never succeeded.
