Huawei Honor 4C Index and Troubleshooting Thread

Due to the fact that all guides, rooting threads about the Huawei Honor 4C are scattered all over the XDA and hence are difficult to be searched for when needed, I decided to create an index thread to keep all ROM updates, rooting and unlocking guides in one neat clean thread.
I’ll try my best to keep this thread updated as soon as new information is released from trusted sources or whenever new mods, ROMs, etc. are released.
You can also post your queries here and I'll try my level best to answer them.

Upgrading from Kitkat to Lollipop
Always try to take OTA updates whenever possible as user data isn't wiped. However, if you want to start anew, just use the below listed methods. ​Backup all important data on internal storage before performing upgrade. Internal Storage will be completely wiped after upgrade. Ensure battery is fully charged or at least 30%. Do not press any button nor attach your phone to charger after the upgrade process is initiated.​Normal Upgrade (Upgrade using the Software Updater)
Download the Lollipop Stock ROM according to your region. See Stock and Custom ROMs > Download Links section for download links.
Ensure your SD card has atleast 3.0 GB of free space.
Extract the downloaded *.zip or *.rar and copy the dload folder (with the UPDATE.APP in it) to the root of your SD card. (In some update packages, there might be multiple UPDATE.APP. Hence copy the UPDATE.APP with has the largest file size)
Insert the SD card (if not already) and navigate to Settings > Update > Menu > Local Update > Full Package:UPDATE.APP . Now finally press Install.
Your phone will reboot to recovery. Wait for the progress bar to finish. When it does you phone will switch off. Hold the power button to switch it back on.
First boot might take some time due to app optimization hence be patient.
Forced Upgrade
Download the Lollipop Stock ROM according to your region. See above section for download links.
Ensure your SD card has atleast 3.0 GB of free space.
Extract the downloaded *.zip or *.rar and copy the dload folder (with the UPDATE.APP in it) to the root of your SD card. (In some update packages, there might be multiple UPDATE.APP. Hence copy the UPDATE.APP with has the largest file size)
Insert the SD card (if not already) and Power Off your device.
Now while holding Volume Up and Volume Down buttons, hold the Power button to power on the device and boot straight to Software Upgrade Mode.
Wait for the process bar to finish. Device will automatically reboot after the upgrade has completed successfully.
First boot might take some time due to app optimization.
Downgrading from Lollipop to Kitkat
Method 1
Download your current Lollipop ROM (see the first section for download links) and the Kitkat ROM you want to downgrade to.
From Lollipop Stock ROM: First copy UPDATE.APP located in 0_CUSTOM_PACKAGE\MiddlePackage\dload to dload directory in the root of your SD card.
Use any of the method posted in Stock and Custom ROM > Upgrading from Kitkat to Lollipop section to flash the Middle Package UPDATE.APP. Skip the copying stuff in those sections.
After the flash has completed, delete the existing UPDATE.APP.
From Kitkat Stock ROM: Copy the Main UPDATE.APP (one with the larger size) to the dload directory in the root of your SD card..
Use any of the method posted in Stock and Custom ROM > Upgrading from Kitkat to Lollipop section to flash the Main Kitkat UPDATE.APP. Skip the copying stuff in those sections.
Method 2
This method requires ROOT SU privileges on your device. Also please make a backup before proceeding.​
Make a TWRP or CWM backup. If something goes wrong, you must have something to restore from.
Download and install Terminal Emulator from Play Store. Open the app and execute the following commands (grant SU privileges when prompted):
Code:
su
mount -o rw,remount /system
Open your favorite File Manager which supports browsing / partition and obviously Root permissions , and navigate to /system.
Search for build.prop and open it.
Find ro.product.model and change it's value to balong.
Save the file and make sure permissions are set to -rw-r--r--.
Reboot you device, flash Stock Recovery and any Kitkat ROM you want. See Unlocking Bootloader, Rooting and Custom Recoveries > Restore Stock Recovery for flashing Stock Recovery instructions and Stock and Custom ROM > Upgrading from Kitkat to Lollipop for Stock ROM flashing methods and instructions (You have to use the FORCED METHOD to flash).
Flashing Stock ROM in cases of bootloop or otherwise
If you are stuck in a bootloop, device keeps on restarting follow this guide.
Before you follow this guide, perform a FACTORY RESET on your device. If this doesn't work, then continue.
Download the ROM version currently on your device or any newer one. See Stock and Custom ROM > Download Link section for download links.
Ensure that you are on Stock Recovery. If not see Unlocking Bootloader, Rooting and Custom Recovery > Flashing Stock Reovery section to flash Stock Recovery.
Use the Forced Upgrade method in Stock and Custom ROM > Upgrading from Kitkat to Lollipop section to re-flash the Stock ROM.
Flashing Stock ROM when device unable to boot to recovery or update mode
Alright! So your phone is completely messed up and you can't boot to recovery or anything. Well this guide is for you! Resurrect that device!​Always use original data cable that came with your device for flashing stuff. It is not necessary but recommended.​Installing ADB / Fastboot and Necessary Drivers

Availability of Stock based Custom ROMs and AOSP based Custom ROMs
Unfortunately, light is pretty dim here. There are no Custom ROMs available for this device. However KangVIP Custom Stock Based ROM is available for the Chinese Variants but I couldn't get the links because they want you to register first. Also, because Huawei hasn't published the chipset source code, so no CM or AOSP based ROM has been developed for this device.

ROM Addons and Miscellaneous Guides​Xposed Framework on EMUI 3.0 and EMUI 3.1
On Kitkat EMUI 3.0, Xposed works only when Use System Hooks is disabled in Xposed Settings. This means that modules such as Gravity Box, Minminguard won't work! However, modules that don't modify the UI work without problems.
On Lollipop EMUI 3.1, Xposed works flawlessly and great! See my thread here for instructions and details: http://forum.xda-developers.com/android/general/guide-workaround-running-xposed-t3338765
Viper4Android Sound Mod
Unfortunately, Viper4Android is a no go on EMUI 3.0 and EMUI 3.1. There is partial support i.e. the mod will only work when it is running in background and will not work on stock EMUI apps such as Music. Also be sure that after installing, DTS Sound Engine will be disabled (or won't work in most cases)!
L Speed Mod for Android Lollipop EMUI 3.1
This mod works flawlessly and I'm loving it! Visit the XDA thread for all information.
Changing Region
This is some really risky stuff. If anything goes wrong you'll end up with a bricked device. I have personally tested this and have successfully changed my region from Pakistan to Malaysia. Nothing will go wrong if you carefully follow the instructions!​Prerequisites
Your device must be rooted.
ES File Explorer installed (no other Root Explorer should be used).
Backup of your stock ROM.
OEM Info File Download Link
Instructions
Dial *#*#2846579#*#* from your device to pop up Engineering Menu. Go to Network Information > Country / Vendor Info. I have listed some of the vendors below:
1. hw/spcseas – Malaysia
2. unicomelectric/cn – China
3. hw/meafnaf – Pakistan
4. mts/by – Belarus
Open ES File Explorer, switch to Root Mode and navigate to /data/. Open custom.bin using ES Note Editor. Clear the Vendor Information text in it and enter the text corresponding to the region you want to switch to. In my case as I switched from Pakistan to Malaysia, I cleared hw/meafnaf and inserted hw/spcseas. Save the file and make sure it's permissions are set to rw-rw-rw
Extract the OEM File Info and copy the oeminfo file of the country you are switching to. Using ES File Explorer, navigate to /dev/block/platform/hi_mci.0/by-name/ and paste it there. Replace the file currently present. Don't delete it! Now set it's permissions to rwx-rwx-rwx.
Finally reboot your device and enter Engineering Mode to verify Country/Vendor.
Download the latest ROM of the Vendor you switched to and flash it using Forced Flash Method. See Stock and Custom ROM > Upgrading from Kitkat to Lollipop for details.
Extracting Update.APP
This is a simple and straightforward guide! Follow and follow...​
We'll start by downloading Huawei Update Extractor. Visit the XDA thread and scroll down for links.
Extract the downloaded file in a safe folder and launch HuaweiUpdateExtracter.exe
Make sure Profile is set to Unknown (worstenbrood).
Switch to Extract tab and locate the Update.APP. (Well you must have downloaded the Stock ROM. No! No problem! See Stock and Custom ROM > Download Links section for links).
Hold down Ctrl Button and select the partitions (such as System, Recovery, Boot, etc.) you wish to extract. Then right click on any one of the selections and click Extract Selected.
Browse for a location where you wish to extract the partitions (or images).
Tada! It's done!

The problem is, Germany is not on the country list during sign up.. So you can't create a phone account using a Germany phone. Huawei has made it an obligation to use a phone account for unlocking.

Alright... Then try this method (it does the same thing as region change does). You must be ROOTED.
1. Open build.prop located in /system/.
2. Change ro.product.model value to Balong.
3. Restart your device.
4. Now flash away any Kitkat ROM of any region.

No manufacturer wants the end user to downgrade to a lower version. You have to be rooted and bootloader unlocked in the first place to downgrade. The middle package is in B330 Lollipop ROM. You may try flashing it but I doubt it will work on B360.

No, you don't need to be rooted. Also this is completely safe. Huawei Recovery won't flash the file it is not compatible so feel completely safe to try it!
I was on B330 Lollipop ROM and I did downgraded mine to Kitkat just for Xposed!

im using b360 lollipop. now i will try to flash the middle package of b330 to downgrade mine to kitkat. im hoping it will work.

@mfbcool If you're challenging my info , Our Phone Support 4G LTE Network!! one thing and 2nd thing, we have Sources for chipset of Our devices but thats are for Arm only not Arm64, so they are less used for us,,, we only need a developer,,, and third and last one, we can never change region as mentioned above and in carbontesla.com, i already read it, but thats not the way!! we needed vendor files which are available only for Pakistani one Rom (B120) and Indian (B390) only,,, not present for chinese or any other region,,, so we cant change region!!
@inshaalmirza
---------- Post added at 02:06 PM ---------- Previous post was at 02:03 PM ----------
@ijameslargo you dont need to be rooted and unlocked bootloader for downgrading, you can downgrade to any version from any Rom,,, if you have done in any way then its ok, if not then tell me, i will guide you!!

My turn!
1. So my desktop computer supports WiFi cards but it hasn't one installed so it neither can't search Hotspot networks nor can't create one. Same case here! The Kirin 620 SoC has SUPPORT for 4G networks but the radio module required to make it available is not installed ON THE HARDWARE on our 4C (it's installed on P8 lite though) or IS DISABLED ON THE HARDWARE SIDE.
2. There are more things required to build Custom ROM other than kernel sources (which you are of course mentioning about). You need open source drivers for CPU Management, GPU, WiFi, Bluetooth, Dual SIM card, Graphics Stack, Radio Bands support, NFC, etc. Unfortunately, those aren't included or open-sourced in the source. That's why the only custom ROM ever made for Kirin SoC, the Cyannogen Mod 11 for Honor 6 has no support for Bluetooth, NFC, USSD Execution, etc. The developer for that ROM made seriously tons of patches and spent countless weeks to make it happen. That's also the reason why there is no CM (or any AOSP) ROM for even high end Huawei devices such as Mate 7, etc. These devices however do have KangVIP ROM which is Stock Based Chinese mockoff.
3. I did changed my region from Pakistan to Malaysia successfully. If that didn't worked for you, I'll upload flashable zips probably in few days that will automatically change the region for you
I wish you ever had a Motorola phone which will hard brick on downgrade (yup a dead phone RIP). Unfortunately no manufacturer wants the end user to downgrade because of security patches, exploits, etc. You can always try flashing system.img of a lower version together with boot and recovery to see whether your phone has downgraded.
That 'balong' method I posted is actually an exploit or more preferably a cheat. The phone loses it's identity, model and version and thus any version either higher or lower can be flashed. However it does require root.

Great great!! You should know one thing too.... You didnot mention CM12.1 of 4X ?? You know, thats made from our Kernel Sources!! Nd dev made all drivers etc for it.... So just sources enough for it...right...
And i once also changed region to malysia/india, but it got balong build,,, then i flashed vendor file of specified rom,,, it changes to its real build!! Then my region was really changed!! And about 4G,,, our hardware support 4G but software didnot!! See in indian Rom, 3 options 2G,3G,4G available in preferred mode!!

You just have to flash the first ROM which is of G-Play Mini's ROM but dont worry....its the solution for everything for 4C...
Now Extract the B330 lollipop ROM, you will have the update.app file of about 2.5GB...
Backup your all data first,,, It may wipe your all data.... dont blame me then...
If you are on currently B390 or any other Build, Flash directly by Putting this update.app in dload folder and then put dload folder in Root of your SD Card...now go to Settings>Updater and then press Menu and then Local Update... you will find the pkg here... just install it...
Now Flash the Vendor pkg present in same folder of B330 if you are converting to indian ROM... flash vendor's update.app in same way as you flash update.app of B330 ROM...
Now you should have B330 installed successfully... and you should have Build number CHM-U01C636B330 otherwise you're gonna get error of 5%
Now Rename the B370 update zip to update.zip and put it in dload folder in root of your sd card..
Now go to updater and then local update... And install update too same as before!!, it will install that update.zip of B370 ROM..
Now you have B370 installed....
Now times to flash the B510 Marshmallow ROM.... rename Marshmallow file to update.zip file and then do the same procedure we do for installing B370 ROM...
Now flash the Patch for B510 by HassanMirza01.zip file attached below using twrp recovery (Link and method for TWRP) and you will have the option of local update in B510... then flash B521 using local update method.
Then do same for B521 update like we do with B510.... after successfully flashing... Phone will booted again and BOOM!!
Latest Marshmallow now installed
Also Here is the Link for Full Marshmallow Rom in case above MM file stuck or whatever, Link for Full Marshmallow ROM B510
Flash it on B370 or G Play mini ROM, it will install whole Marshmallow ROM.
For any question, ask below.....
In Case you dont like this Rom, and you wanna downgrade to Lollipop again, here is the Link for Lollipop Rom
Download it, unzip it, put dload folder in root of sdcard. Now MM dont have local update option so dial code *#*#2846579#*#* in MM Rom, you will see software upgrade option there... Press it and your done
Hit Thanks and Support me if you Like and get help from this thread...Thank you...

I have a question, which recovery you use to flash the zip file?

@Paco_marine stock recovery can flash official zip files OTA updates.. But dont try this method yet... Wait for the final release.

[Guide] Safely unlock bootloader on official MM

UPDATE: This is now unneeded because threr is a faster way ro unlock bootloader on official MM here, he updated for official MM
Hi, I discovered an unlock method for official MM!! This maybe long but's it totally safe
You need:
Adb and fastboot environment ready PC
LP RAW File
Android 6.0 Beta Unlock tool
Android 5.0 One-Click Unlock tool
First version of beta MM (Z00A) (Z008)
Official MM zip (find it on Asus site)
Thanks to all people upload these links
Just do the following:
Flash the lastest LP via AFT (using raw file given above), wipe all data. If you already on MM, you have to downgrade
Unlock your bootloader using 1 click tool given above
Boot to stock recovery and sideload the first version of beta MM
Unlock the bootloader using MM beta unlock tool above
Boot to stock recovery
Two case here:
Case 1: You can't boot stock recovery
Normally boot your phone (to Android)
Setup it as a new phone
If it shows there is a new firmware, don't update!!!
Enable Developer options, then enable usb debugging
Copy the official MM zip to external sd card
Open command prompt, run adb reboot recovery, accept the adb permission if prompted
After it boots to recovery, select Apply update from SD, then choose the zip file you've copied before
Wait for it to update, it may stuck at flashing splashcreen, don't worry, it's trolling you, may be Asus forgot to update the script
Goto step 7
Case 2: You can boot stock recovery
Sideload the official MM zip (adb sideload <filename>.zip)
Goto step 7
7. Flash this TWRP (fastboot flash recovery <twrp>.img)
8. Root your phone using this method
9. Reboot, if it shows "Your phone has failed verification bla bla..", then you've success. It may reset loop like note 7 in the first time start, don't worry.
9. Enjoy :highfive:
Note: If you're facing with battery problems on MM, factory reset it in Settings > Backup and Reset > Factory Reset > Erase everything
Successfully on my ZE550ML
The warning screen is normal so don't worry and there is no way to fix it for now

Yes, BL will be relocked once you upgrade to MM.
If you want to unlock MM BL(6.0), refer to this thread.
Or you can downgrade to Lollipop referring to this thread. Then your BL(5.0) is unlocked.

Upgrade to MM
Hello folks!
2 week before MM was released i'ved opted to unlock my ZE551ML BL and therefore install twrp and a MM custom ROM..
so here´s the thing i stayed with the ROM for about 3 weeks and honestly..it works very well..but when i knew that 6.0 official was coming out i decided to go back to stock..i did it following manny tuturials avaliable for me to get my BL Re-Locked..but unsuccessfully..so i followed mr_gourav2000 tuturial (http://forum.xda-developers.com/zenfone2/development/stock-rom-ul-z00a-ww-2-20-40-168-t3354526) and reverted to the WW_Z00A-2.20.40.183-to-2.20.40.184 (hopefully i can get the sshot in this post) version...since my BL is unlocked i can´t get no updates..my question is:
Is there anyway to go to MM 6.0 by ASUS with the current status of my phone?
is there anything i can do to revert this??
Cheers to everyone

Just download the update package and rename it to mofd_sdupdate.zip, copy it to internal storage. Then reboot to stock recovery, the update will automatically start. This should work if you have lastest stock recovery

Have you downloaded the correct build? There are build for MM bootloader, if you flash the normal builds, it will fail and reboot to recovery again. Gapps is the same for all builds
After you install that special build, do not update to newer nightlies, it will fail. For updates, check the link i give you and see if there is a new MMBL build.
About that, here is the post: http://forum.xda-developers.com/showpost.php?p=68542370&postcount=8551

hello friend, I tried to install the CM13 ROM that indicated me and I get Error 7 in TWRP 3.0.2.0, I have Android 6.0 (.134) official and if I can change kernel and flash rom SuperSU but change with a new MM Blows I can not (CM13, AICP, beanstalk ....) thanks for your help!

Run the script again (i gave you in above post). Download the CM13 in that link, not in the OP of CM13 thread. Flash that CM13 and Gapps (Gapps is universal for MMBL and LPBL).
May be you have corrupt download, I'm currently running CM13 on MMBL

Hello, I have finally found the solution, the problem is the recovery, the TWRP 3.0.0.2 da failure with new builds, I Flashed next on the link you put me through adb and now it works, thank you very much for everything .

how u unlocked bootloader

Go back to android 6.0

Sorry guys,
Another rollback thread.
I have my P9 lite. I installed twrp recovery + nougat rom.
I have to rollback for some reasons.
I followed :
x to flash android 6.0 europe rom https://boycracked.com/2016/09/14/official-huawei-p9-lite-vns-l31-stock-rom/ the update works but phone is still looping reboot/logo
x a thread of Huawei website here http://consumer.huawei.com/be-fr/support/products/downloads/p9lite-befr.htm, you have to flash an intermediate package (UPDATE.APP) by visiting the official EMUI website
(i founded it with Beni2567 thread on xda) https://forum.xda-developers.com/huawei-p9lite/help/rollback-nougat-7-0-to-mm-6-0-t3555493
Update is stuck at 5% then after few minutes, the phone reboots., then said my device has been unlock, then huawei logo, then reboot again...
I never succeed to go back with a functional android system :s

Man, why not read arround before making stupid mistakes?
First thing to do was to flash Oeminfo!
That because once you are in Nougat, your phone Oeminfo is modified in a way that is not recognized by lower firmware...
That step is included in tutorials arround...
1. flash TWRP (thanks to @BadWolfYe )
2. Flash this file (OEMINFO!)
3. Put the MM UPDATE.APP in the DLOAD folder on EXTERNAL SDCARD
4. Install it using the 3 button method (dload method)
5. Factory reset
6. DONE!!
Now you have a nice bricked phone!

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 .

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.
Finally
Do not forget to click on :good::good::good::good::good::good::good:

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.

Thank you
I'm on emui 5,0 android 7,0 nugat ROM nrd90m test-keys - before I don't remember, upgrade ota for AL10 model. Maybe AL10C00B552.
So I have to try flash nugat ROM AL10 by TWRP 3.1.0.2.
Dload method dont work - I never need sd card for this.
Can I flash nugat rom dload method? And where I find stock recovery for nugat?

TWRP & Erecovery methods

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.

Do I have to format data before start flashing B584.zip or do nothing?
Do I need update_data_full_all_cn.zip ?

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.
