Im on C66 how to update on newer firmware version?

So,
My phone is vns-l21c66b131 and is there any way to update to newer versions without rooting and if possible can someone write steps on how to do it?

If you use <SEARCH> you find followings:
<After a few day of reading users personal experiences regarding upgrade to Android 7 Nougat i make the big step myself...
My device is VNS-L21 model and entire process goes flawless...
Device state was stock MM VNS-L21C432B150, bootloader lock, dualsim enabled.
1. Unlock bootloader folowing by Automatic Factory Reset.
2. Flash TWRP
3. From TWRP i flash Meticulus TWRP
4. Reboot to TWRP and flash update.zip and update_data_full_VNS-L31_hw_eu.zip, both flash ends with errors, without reboot between flashes.
5. After that, i reboot device and boot in system ok, start configuration, etc.
6. I reboot to fastboot and flash Nougat Recovery reworked by @BadWolfYe
I am not experienced camera bug, all works fine and i have now a fully functional phone.
BTW, dualsim remain enabled and works both sims.
Thanks to all contributors for these pieces of firmware, first of all to @BadWolfYe!>
For that's is <SEARCH>, not to open another topic for same problem...

Thanks for the reply, but I'm not talking about Nougat, I talk about MM b161 update. How to do it if my carrier is c66 and the newest update there is b131

If you want to stay on C66 you have to wait to OTA updates...
If you make any upgrade via dload folder on sdcard your phone will go from C66 to C900 (global)
Another alternative is to debrand your phone to C432 (hw eu)
For any of this is treated here in some topics...

So I just need to create dload folder and put the zip there?

Not the zip! Put the update.app wich is in the zip, for this method.
The zip is ok for update from TWRP.

Is that red message verification failed message?
If yes then please unlock the bootloader again even if it says unlocked. Then it will do factory reset and the red message will disappear.
You can then try to flash the stock firmware in TWRP. You can use B368 or B386 stock firmware from another thread and flash in TWRP. That is if you have TWRP. If you don't then unlock bootloader and then install TWRP using SRK tools. You can use SRK tools for adb commands also. Just type 000 on first page off srk tools and you will get into command prompt. Using that push the TWRP into your phone. ADB is very stable in srk tools and it will always identify your device. So that problem you won't have.
I couldn't find a proper rollback for AL10 . May be some one else can give if it is there for this model. If it was L29 model then rollback package is available and you can easily rollback using that in this type of situation.
If the flashing of stock ROM worked then you try to debrand your phone to L29 later. You will have many options then and L29 firmwares are more stable. I have AL10 which I debranded to L29 & I totally recommend debranding to C432 once your problem is solved
Do the above steps only if you are on marshmallow firmware.
Don't forget :good::good::good::good::good:

I created a al10 roll back for all al10 phones. It converts it to a DL0017 dual active sim. Message me for details how to obtain it from me .. MUST have twrp installed .

So maybe you help me unlock bl (I have unlock code) and flash TWPR....

If you want to unlock bootloader through ADB?
Here are the steps.
In your phone go to settings - >developer options - > put usb debubbing ON
switch off the phone.
Press and hold the down button for 3 seconds & then connect it to the computer
It will then go to fastboot mode.
then open SRK tools
type 000 to enter the command prompt.
Type the following command
fastboot oem unlock xxxxxxxxxxxxx
In this command xxxxxxxx is your bootloader code. just replace xxxxxxx with your code and press enter.
This will unlock your bootloader & will do a factory reset.
In SRK tools there is an option for bootloader unlock but I think that is only if you are in EMUI 4.0 or EMUI 4.1 that is what I think may be anyone else who tried this option in android 7.0 can confirm but the adb commands will work.
I have enclosed screenshots for better understanding.
you have mentioned that you are in Android 7.0
Can you tell me your exact firmware that you have on your phone at the moment?
After you get rid of that red message. Your bootloader is unlocked.
There is Erecovery process - > steps below (but there is a problem with this process)
1)Switch off the phone.
2) Press and hold the volume up button and then connect your phone to computer or charger. Yes charger. Then you can download stock firmware through your WIFI - > this will also install stock firmware. But I think this won't work because of unlocked bootloader
So once again install the TWRP for Android 7.0 I think it is Twrp 3.0.2 or Twrp 3.0.3 - > this is definitely for nougat.
ADB command to install twrp recovery is
fastboot flash recovery twrp.img ( rename the TWRP to twrp.img ) in the adb.
Try to flash the stock firmware zip files in TWRP.
Here you have two options - > You can either try flashing B386 files (only one zip file) or B562 (android 7.0 - > 2 zip files - first update.zip and then the other zip file)
If you are successful in this step then your TWRP will be overwritten with stock recovery.
That is ok. don't worry. Kangvip ROM is pre-rooted ROM. So you will get root in the end. For now its ok to be on Stock at this step.
Stock Recovery + Stock ROM + bootloader locked -> then you can dload back to EMU 4.1 using B386 firmware.
Then you can unlock bootloader (again) yes its a pain + followed by TWRP + ROOT - one after the other in SRK tools its all there. you can use the options in SRK tools this time.
And once you have root again.
Take backup and save it on your SD card. (except DATA , take backup of all options listed there, why? bcoz if you include data - > it will increase the backup size and it will take more time.
*Disclaimer* -> Very tricky & risky process - proceed with caution & full attention
Then - > you can debrand - > to C432 -(debranding is very tricky process, so keep your backup handy) This should be done very carefully because any problem here means you might find less space on your internal memory. Then you will have to restore that backup to get back your space.
Here is the link to excellent tutorial by somboons Watch it carefully.
https://www.youtube.com/watch?v=JZVsIKtdgV4
Just follow that as it is for debranding from AL10 to L29-C432
I am very very sorry for all these confusing and tricky steps. Please proceed with caution when you are doing the debranding process. Do not get diverted during that process.
Yes I did all this when I debranded my Huawei Mate 8 AL10 to L29. I had lot of anxious moments, doubts & my mind started playing tricks if mate 8 was dead on few occassions. But in the end my phone prevailed. Now I am happily using L29 - Kangvip B577. That is where I want you to land up in the end.
Do not worry and do not panic any time. Be prepared to face few challenges during this process. I will help you but please share your experience and follow the steps carefully.
During debranding you might have your phone rebooting or something might happen. That time do factory reset and continue from where you left off. If you get red message - > then you have to unlock bootloader. Otherwise continue.
This whole process will test your patience & consume time. So I hope you are willing to do this. Its worth it. I learnt my lesson, I am never buying chinese version of Huawei phones/tablets again. Only European models from now onwards.

TWRP 3.1.0.2 is actually used for flashing nougat firmwares.
Which firmware are you on right now?
Are you on nougat or marshmallow? Please provide the full firmware build number.
if your phone is on marshmallow.
TWRP version depends on your firmware.
If you are on EMUI 4.0/4.1 then pls use the TWRP 3.0.2
you can use SRK tools to install that TWRP if you are on EMUI 4.0/EMUI 4.1
Install that version. Then
Factory reset
Flash the B386 zip file in TWRP.
You can get the B386 from here https://forum.xda-developers.com/showpost.php?p=69331930&postcount=1338
If your phone is on Android Nougat.
Then you have to use dload method.
Unzip the B386 zip file.
Put the update.app in the dload folder inside your external sdcard.
Go to your dialer
*#*#2846579#*#*
Select "software upgrade"
then Select - > SD card upgrade.
And then it will reboot and install the stock firmware.
This thread has all the Stock firmwares.
https://forum.xda-developers.com/mate-8/general/huawei-mate-8-stock-firmware-official-t3391727
Hope the above steps solve your problem. If not, then we will try something else. please answer all the questions to help you better especially your full build number (firmware version).

Since you are on nougat with test keys, try to flash the latest nougat firmware on your phone model NXT-AL10 (Try flashing firmwares using TWRP )
Link for the firmware
link 1 https://mega.nz/#!Y4IVEbxY!7C8u3FP3V8eAV4jVNmbRUfj2W1nc8p5gMtaScVmzeA0
if the link 1 doesn't work then try link 2
link 2 https://mega.nz/#!U9ZkTZzI!fbPnyDIxCGGFkiGxtF3SMicLqmTDNTq8SG8fVw8lfz8
download & flash it using TWRP.
Once you finish flashing - you should have android nougat stock B584
Go to settings - > about you should see that B584. in build number.
If your build number is showing anything other than test-keys then you will be able to use dload method or Hisuite method using PC.
Now if IT IS showing B584, then you can dload to B386. then unlock bootloader -> TWRP using SRK tools - > Root - > and then debrand to L29C432. - > this is the road map for you. we will go through this only after you succeed in the above steps.
Try the below steps only if the above steps don't work
if you want to flash the nougat recovery
then unzip the zip file in link 1.
Use Huawei update extractor software HuaweiUpdateExtractor_0.9.9.3
and then extract the recovery.img from the update.app file.
now
switch on usb debugging in your settings.
switch off the phone
press & hold volume down and then connect to phone to laptop
put the extracted recovery.img file in the same folder as the SRK tools
open SRK tools
type 000 to enter command prompt
type fastboot flash recovery recovery.img
(please remember all these steps that use adb commands come with element of risk. so please proceed with caution and go slow. Proceed with these steps only if you know what you are doing otherwise do not proceed)
Try the TWRP steps first and see if that will resolve your issue before flashing any stock recovery. If your flashing through TWRP then it will install stock recovery & stock ROM.
Please share your progress.

Glad to read Ur kind words but V have a long road ahead. So let's fix ur phone :good:
Answers
1) Yes, you can format DATA before flashing this zip file. you can also do factory reset before flashing the zip file. (Remember we are doing this step only to get ur phone out of that test keys & this firmware is not ur final firmware that u will use. )
2) I was searching for a firmware that u can flash on ur phone and I found B584 and felt this might help. The guys in the other thread mentioned it as full firmware. After u flash this firmware, check in settings - > about - > build number if it is anything else other than test keys then u succeeded in this step.
Goal of this flashing of B584 is only to get rid of that test keys in build number. Once that is gone then U can downgrade to B386 using steps in my previous posts followed by the road map.

Rebranding to FRD-L09c10 OREO (russian)

I have found this tutorial in the comments of a tread, and it worked for me, so I decided to bring this tutorial in a new tread so everybody can easily see it:
Thanks hackslash for this tutorial.
To rebrand, you need an unlock bootloader.
1. Download the C10 oeminfo file https://mega.nz/#!aBhnDKAK!qeVVAjcApTl7fqjwHcPMUS6ITUDHL9Rx0u-4k8rx0c4. It is a zip file, extract it to find an img file. Reboot to TWRP and select Install Image and install the file to oeminfo partition.
2. Perform a complete factory reset in TWRP.
3. Download the latest Nougat (3 files package) for FRD-L09C10 through Firmware Finder. Flash it using HuRupdater https://forum.xda-developers.com/honor-9/development/tool-flash-official-firmware-recovery-t3769279.
4. After the flash is complete, reboot the device, unlock the bootloader again and flash TWRP.
5. Download the latest Oreo build for FRD-L09C10 through Firmware Finder. Using HuRupdater flash the three Oreo firmware files. Don't perform a factory reset this time.
6. Reboot your device. You're now on Oreo.
(brightness dimming still happening in some apps on oreo)
(I also have tested Pixel experience treble (GSI), and guess what? I got in bootloop, yeah... thanks huawei for the amazing software work ...)

Will I Be Able To Install Unapproved Updates With HurUpdater?

@SuperSwordSmasher Yes you can install every stock firmwares.

@immichao - can you correct the links as they do not work

Deleted

Just updated the links

About GSIs, there are special GSI for Kirin devices. And don't worry they'll be released by the OpenKirin team with support for Honor 8 shortly.

[SOLVED] NRD90M test-keys - Nougat Stock Firmware Huawei Mate 8

Hi all,
I just want to share with you all how i solved NRD90M test-keys on my Mate 8. 2 weeks ago, I've successful to debrand from L29 to AL10 and updated to Oreo EMUI 8. After awhile, i found bugs or error when i connected to PC or Laptop, my phone will go haywire like someone is touching the screen everywhere. I suspected it might be came from cust.img that i flashed to make sim and data detect.
Then i made a decision to debrand again to DL00, and successfully rollback to MM B386 using Hisuite version 8. After that i flashed dualcu_cn.zip using TWRP and successful to debrand to DL00. I checked the OTA update, there is DL00C00B577 Nougat update and i download and installed it. My Mate 8 became NRD90M test-keys after successfully updated to Nougat. For one and a half day i searched in internet and XDA on how to get rid of NRD90M test-keys and update to next build of Nougat. On XDA, I've found several thread regarding NRD90M test-keys like https://forum.xda-developers.com/mate-8/general/info-rom-nrd90m-test-keys-android-7-0-t3750147, https://forum.xda-developers.com/mate-8/help/nrd90m-test-keys-t3549124 and https://forum.xda-developers.com/mate-8/help/stuck-nrd90m-test-keys-t3590461 but without proper steps and procedures. So people like me a noob or newbies will stuck on how to solve the problem. So I've do some test for my Mate 8 by using one of this methods which are HuRUpdater, HWOTA and erecovery. I can said that 90% of chances rate it will success but you'll need to download FullOTA-MF stock firmware. I'm using erecovery so no need to download it.
Requirement:
1. Unlocked bootloader
2. TWRP Installed
3. HuRUpdater - Link : https://forum.xda-developers.com/honor-9/development/tool-flash-official-firmware-recovery-t3769279
4. HWOTA - Link: https://cloud.mail.ru/public/DEWc/a9fDVbgpz
5. update.zip - FullOTA-MF (for me NXT-DL00C17B592-full in erecovery)
6. update_all_hw.zip
7. update_data_public.zip
8. Back up your data using HiSuite or SD card.
Instruction
Method 1 using HuRUpdater
1. Make sure your bootloader is unlocked and TWRP is installed.
2. Download HuRUpdater.zip, update.zip-FullOTA-MF (your stock firmware), update_all_hw.zip and update_data_public.zip.
3. Make a new folder in SD Card root (you can name it base on its firmware) and put all the zips that you already downloaded in the folder.
4. Boot your Mate 8 to TWRP and choose sd card > folder > HuRUpdater.zip. It'll reboot into recovery and start flash firmware.
5. Your phone will update to the newest build number base on your stock firmware.
6. You can follow the steps in this link https://forum.xda-developers.com/honor-9/development/tool-flash-official-firmware-recovery-t3769279
Method 2 using HWOTA
1. Make sure your bootloader is unlocked and TWRP is installed.
2. Download HWOTA.zip, update.zip-FullOTA-MF (your stock firmware), update_all_hw.zip and update_data_public.zip.
3. Extract HWOTA.zip into HWOTA folder in your PC and put all the zips that you already downloaded in that folder. Copy HWOTA folder in your SD Card.
4. Boot your Mate 8 to TWRP and choose HWOTA folder and select nxt_hwota_update.zip. It'll reboot into recovery and start flash firmware.
5. Your phone will update to the newest build number base on your stock firmware.
6. You can follow the steps in this link https://forum.xda-developers.com/mat...ate-8-t3785320. This HWOTA.zip also can use to flash OREO EMUI 8 firmware.
P/S: I think HuRUpdater and HWOTA is the same method but using different script binary.
Method 3 using eRecovery
1. Press Vol + and Power button at the same time for 3-5 sec.
2. Choose your WIFI (need strong connection), if not it will failed to download recovery firmware.
3. If your WIFI have a strong connection it'll start to download recovery firmware and install.
4. Wait until finish installation
5. Your phone will update to the newest build number base on your stock firmware.
P/S: If you're using C636,C432,C185, i think it's useless. because i'm from C636 it's never captured the recovery firmware. so in case if your phone bricked or test keys, you can use HuRUpdater method. This method only working on chinese variants is what i think.

Hi all,
I just want to share with you all how i solved NRD90M test-keys on my Mate 8. 2 weeks ago, I've successful to debrand from L29 to AL10 and updated to Oreo EMUI 8. After awhile, i found bugs or error when i connected to PC or Laptop, my phone will go haywire like someone is touching the screen everywhere. I suspected it might be came from cust.img that i flashed to make sim and data detect.
Then i made a decision to debrand again to DL00, and successfully rollback to MM B386 using Hisuite version 8. After that i flashed dualcu_cn.zip using TWRP and successful to debrand to DL00. I checked the OTA update, there is DL00C00B577 Nougat update and i download and installed it. My Mate 8 became NRD90M test-keys after successfully updated to Nougat. For one and a half day i searched in internet and XDA on how to get rid of NRD90M test-keys and update to next build of Nougat. On XDA, I've found several thread regarding NRD90M test-keys like https://forum.xda-developers.com/mate-8/general/info-rom-nrd90m-test-keys-android-7-0-t3750147, https://forum.xda-developers.com/mate-8/help/nrd90m-test-keys-t3549124 and https://forum.xda-developers.com/mate-8/help/stuck-nrd90m-test-keys-t3590461 but without proper steps and procedures. So people like me a noob or newbies will stuck on how to solve the problem. So I've do some test for my Mate 8 by using one of this methods which are HuRUpdater, HWOTA and erecovery. I can said that 90% of chances rate it will success but you'll need to download FullOTA-MF stock firmware. I'm using erecovery so no need to download it.
Requirement:
1. Unlocked bootloader
2. TWRP Installed
3. HuRUpdater - Link : https://forum.xda-developers.com/honor-9/development/tool-flash-official-firmware-recovery-t3769279
4. HWOTA - Link: https://cloud.mail.ru/public/DEWc/a9fDVbgpz
5. update.zip - FullOTA-MF (for me NXT-DL00C17B592-full in erecovery)
6. update_all_hw.zip
7. update_data_public.zip
8. Back up your data using HiSuite or SD card.

So originally you came from NXT-AL10 and without changing oeminfo with SRK Tool then you used the HuRUpdater?
Is it your bootloader still unlocked or locked?

I did not change oeminfo, or rather I tried with SRK tool, but I did not succeed.
Yes, I used HuRUpdater.
Bootloader unlocked

TWRP Huawei mate 8
Hello, my people, how are you?
I have a doubt, the truth is I am very new in this.
I have a Huawei Mate 8 NXT-L29 which updates to Android 7 with an app called "Firmware Finder for Huawei" and then I started my problems, the clock does not work, I can not enter the updater among others. What I would like is to change that rom for another or if it were for a stock.
I have the bootloader open and a TWRP (twrp-3.2.3-0-next) which is the only one that has worked for me but I have not been able to install another rom it tells me this: "error when dismounting" / '/ cust /' (invalid argument) and I do not know what I'm doing wrong ...
the compilation that this app left me is: NRD90M test-keys
and the rom that I want to install is: NXTL26C605B580
I would like to know your recommendations and corrections to what I am doing and thank you and I apologize for my English, which is very bad!

Try to install Service ROM from SD card using dload method.
Link:
https://androidhost.ru/41d
Follow instructions in file "ReleaseDoc". (Read everything carefully before doing anything).
Through this process, your data will be deleted and bootloader will be locked again.
Dload method works with Stock Recovery only, you have to install Stock Recovery first.

Hey dude !!
So you bricked the device ....
I don't know why but if you want B412 firmware
you can use @-Alf- guide and re-upgrade via Firmware Finder
to B370 fullota-mf-pv first, then to B412 fullota-mf...
Or download a previous from B412 firmware (ex: VNS-L31C432B410 fullota-mf)
and use HuRupdater method to flash the firmware.
Extract then stock recovery from B410 via Huawei Extractor and flash it via TWRP.
Re-update finally to B412 using Firmware Finder.
I can help you doing this, worked on my ex device but i can't guarantee 100%.
Cheers

Piece.

Hello,
I reinstalled the custom rom that I found on the net: C432B414 with Hurupdater.
It works.
However, the bootloader is still unlocked ... however, I would like to return to the factory configuration with the bootloader locked.
https://www.cjoint.com/c/JItgZO6GuGB
I have the stock recovery install :
https://www.cjoint.com/c/JItg7SqQmdB
I am currently downloading the file indicated by this link : https://androidhost.ru/41d
