You need roll back package for L29. It will be around 90 mb. Put it in dload folder in sdcard. Then go to dialer and type *#*#2846579#*#* and then select software upgrade. It will reboot and will undergo that process or you can do that three finger process. Once it is done you can reboot back to your OS. This time put the B1xx or B3xx firmware in dload folder and try to do that again. It will go back.
In my case I went back from L29C432B560 to L29C432B180 doing this way. I am saying this from my personal experience. Key here is the rollback package from Huawei. It is there in one of the threads or you can google Huawei rollback package. Once you get that you resolve your issue.
Another thing I observed is locked bootloader.
Hope it works out for you.

Go to this link
http://m.huawei.com/mymobile/consumer/support/downloads/index.htm
And select the last one L29C900B500
That is the one I used.
If that code doesn't work then try the 3 finger rule
After you do with this rollback package
You will once again come back to nougat
You can check the build number if the process is successful.
Then you have to dload again to B180 or B3xx
Hope this works for you

Don't think it will make any difference. You may try to install update.zip (EMUI 4.0) via twrp.
Just checking. Is your FRP unlocked?

How to Rollback from Nougat to Stock - Mate 8 - L29

Click to expand...

I had the same problems.
option 1
I downloaded stock B560 zip files
flashed it in TWRP
next I locked the bootloader
now the dload to rollback - worked. buildnumber - changed
then another dload to B180 to go back.
after that I did dload to B190
updated to B560 using system update. then I flashed kangvip B577 and its all good now.
my phone was debranded to L29c432 so I used these files.
you have to get the right set of files for your phone model especially stock firmware.
roll back package from here
http://m.huawei.com/mymobile/consumer/support/downloads/index.htm
locked bootloader and stock recovery did the trick for me.
hope it works out for you. :good:

You can change by switch off your phone then press volume down and plug in your usb cable. It will bring you to bootloader mode. From there it will tell you bootloader and FRP status

Frd-al00's rollback is different from l04.
If you are in official emui 5.
I suggested you download hisuite in huawei website, and then connect your phone to pc, click system update in hisuite, you will see rollback button.

I have REBRAND AL00 to L09 by https://forum.xda-developers.com/honor-8/how-to/guide-honor-8-to-frd-l19-t3632220
Pls help me from L09 back to AL00?
I don't have back up rom AL00, only back up OEM info

Interesting discussion. so is 360 the only version you can do a straight flash back to in TWRP, or is there a newer version?
Can the stock rom be rooted using Magisk or SuperSU - can one of them be flashed immediatedly after flashing the update zips before rebooting, while twrp is still loaded?

Rommco05 said:
B360 is first stable Nougat for most models and I starting from this firmware and after update device with OTA. Yes supersu works, I was using modified supersu wich is posted in twrp thread by openkirin team and I always install them after first boot to rom
Click to expand...
Click to collapse
Yes, but if you flash back to b360, it doesn't take OTA updates, and I don't want to relock the bootloader.
The main issue I have with stock is the inability to turn off the battery charging LED - it really annoys me.

Help.
Been messing around. I'm now on b380 but camera doesn't work and updates don't work. I've lost twrp, and if I try to install it it fails, although my boot loader says it's unlocked. It's there a way to flash the restore from a pc if I can't get twrp reinstalled?

Eventually resolved by downloading rollback package and b331 from Huawei site, and putting the update.app from each in dload on the sd card and forcing flash.

If this is a full firmware when you will extract it you will find a dload folder in this there will be update.app just copy dload folder to SD and start flashing with three buttons.
If this is a ota file you just need to put whole update.zip in dload folder and start flashing....

You can try getting the unlock code using the IMEI and serial number on the box, unfortunately no product ID is on the box try some product id generator or using dc unlocker... It's the only known way to get the unlock code in such situation.

I think it's a manual process as its submitted in Google forms, even I have requested a unlock code on Saturday, I can't remember where I stored the original one or weather if I ever saved it at all. But luckily my device update was successful... B404 only had to factory reset and the bootloader was locked.
Will let you know as soon as I receive it, and you let me know too when you receive it :fingers-crossed:

You should always backup your bootloader unlock key instead of requesting it everytime. Anyways, once you do get your unlock key, unlock the bootloader and do the following steps to restore your device:
Grab Honor View 10 TWRP from here: https://dl.twrp.me/berkeley/ and flash it using the command below:
Code:
fastboot flash recovery_ramdisk twrp.img
Replace twrp.img with the name of the recovery.
You now need EMUI 5 firmware. Go to firmware finder and download the firmware which is FullOTA-MF-PV (must have PV in the end). Copy the firmware to your SD-card. For you it should be B394: http://update.hicloud.com:8180/TDS/data/files/p3/s15/G1774/g1755/v101649/f1/full/update.zip
Now reboot your device to TWRP. It might take some time to boot to TWRP so do wait.
Once rebooted, install the update.zip file.
Reboot to system from TWRP. Your device will automatically perform a second stage install and a complete data reset.
Hooray, you're back to EMUI 5.
Now again unlock bootloader and flash EMUI 5 TWRP. Now install this zip: http://update.hicloud.com:8180/TDS/...-L09_hw_eu/update_data_full_FRD-L09_hw_eu.zip
Perform a final factory reset via erecovery and you're done.

You should always backup your bootloader unlock key instead of requesting it everytime. Anyways, once you do get your unlock key, unlock the bootloader and do the following steps to restore your device:
Grab Honor View 10 TWRP from here: https://dl.twrp.me/berkeley/ and flash it using the command below:
Code:
fastboot flash recovery_ramdisk twrp.img
Replace twrp.img with the name of the recovery.
You now need EMUI 5 firmware. Go to firmware finder and download the firmware which is FullOTA-MF-PV (must have PV in the end). Copy the firmware to your SD-card. For you it should be B394: http://update.hicloud.com:8180/TDS/data/files/p3/s15/G1774/g1755/v101649/f1/full/update.zip
Now reboot your device to TWRP. It might take some time to boot to TWRP so do wait.

hello and thanks for your help, a question, before installing the update.zip I have to do the wipe data restart in recovery and do another wipe as in custom rom?
