[For FRD-L14 Users] Here is how to restore/downgrade to EMUI 4.1/MM Build

So, just like others I have been itching to install the Nougat beta and boy what a ride I had. I used the Charles method and installed the beta successfully. While install was great, the software was not. I had several things missing and It did not go well.
First and foremost, beta is ONLY for FRD-L04 models which is the US 32GB single sim version and NOT for the FRD-L14 64GB models. The beta build really screwed up my phone and I had to downgrade to official MM build. The software doesn't really tell there is a mismatch in the model as technically they are the same specs except for the storage.
To downgrade, I read this thread and then downloaded and restored from the image from the Honor 8 downloads page. Restored to MM successfully but guess what, my model number showed FRD-L04 and not FRD-L14. This was a problem. Why? Well, it turns out when you set up Android Pay, it clearly tells that I am running a custom ROM. While all day to day function work right, you are still running a custom rom as you are not running the software for FRD-L14.
Honor 8 site does not have the restore image in their downloads page. I called their support and they acknowledged that the restore image available is not for FRD-L14. They are working on it to see why they don't have this image available for download.
So, how do you restore?
Thanks to this thread, I was able to get the full image. Below are the links:
1. update.zip
2. update_data_full_hw_usa.zip (only if you need the bloat)
Download those and flash them from SD card as described in this thread. That will get you the MM build. Below is the build number you should be if you are in MM:
- FRD-L14C567B162
Hope tha helps.

@digitalbreak
Although your post is very informative your missing some key elements.
Where is your Rollback Update.app zip ?
The correct way to restore MM from Nougat is to flash rollback and then your last full update.zip (B162 ?)
you could try the one for the L04 here >> http://download-c.huawei.com/download/downloadCenter?downloadId=92098&version=360320&siteCode=us
the link you posted to FRD-L04, Android 6.0, EMUI 4.1, C567B122 is useless and just makes it confusing
Also flashing the update_data_full_hw_usa.zip is how you update the /cust partition
that's where your Local.prop is stored and that's where your phone gets the information displayed in the Settings / About screens.
So if you had not previously changed the /cust their would be no need to flash it again after the Full update.app is flashed.
You would be able to tell this if your Settings/About screens are wrong after the flash.
Also you state that using the Charles method did not go well ? That's really not possible, because this method downloads the files directly from Huawei servers
and the update is the same as if the OTA were pushed to your phone. Only real way to mess that up is to input the wrong response in Charles App and download the wrong update. If you had linked the correct FRD-L14C567B360 file in Charles you would have had no problems.
Bottom line
If your on Nougat Beta and you want to return to MM
you simply dload flash the Rollback and then the Full B162
and you should be back to stock. If Settings / About is incorrect
dload flash the update.app inside the update_data_full_hw_usa.zip
And just for reference here are all the files available for you phone >> http://hwmt.ru/oth/HWFF/info/view.php?find_model=frd-L14
And to get the correct update_data_full_hw_usa.zip for each version
just edit the update.zip download link
Code:
http://update.hicloud.com:8180/TDS/data/files/p3/s15/G1278/g104/v72029/f1/full/update.zip
to http://update.hicloud.com:8180/TDS/data/files/p3/s15/G1278/g104/v72029/f1/full/[COLOR="Red"]hw/usa/update_data_full_hw_usa.zip[/COLOR]

Unfortunately that doesn't help for FRD-L14, at least for me as it didnt succeed. I tried the included manual step by step but it did not restore to MM.

If I am not wrong, when you use Charles method and download the update, it applies those and hence since I had pulled L04 update into my L14, the /cust was changed by the OTA.

In the sense that I had pulled the update for the wrong model. It was hard to find that the beta program was only for FRD-L04 and not for FRD-L14. And that thread is so long it is difficult to even guess that if you are a newcomer.

In theory yes and works well for FRD-L04. I couldnt find the builds in Honor's web site for FRD-L14. Getting to know the servers from other methods is OK, but thats not how most customers do. We geeks do that

I can do the rollback but I just realized that I have the 64GB version which is the FRD-L14
http://www.phonemore.com/huawei-honor-8/models/629
I'm not sure if there is a FRD-L14(64GB) variant of the MM firmware available anywhere. If so, I'm not aware of the link of the site to find it. Secondly, if I do install the FRD-L04(32GB) variant of the MM firmware would that create problems for the phone in upgrading and later trying to root and install custom ROM etc.
Much Thanks

Installing the FDR-L04 image on FDR-L14 will tell Google that you are using an unidentified or a custom ROM version. That will limit certain services/apps like for example Android Pay and even sometimes updater to work. Android Pay certainly didn't work for me. Some say its just a file that contains the hardware info that needs to change while the rest are the same, but I have had no luck with that approach.

When you rolled back your L14, do you have service like Android Pay? I really want to roll-back since Nougat/EMUI5 have been terrible on battery life. Is it "legitimately" L14 with the 64GB storage?

I just tried this method to get back to MM from N B360. Unfortunately the software always failed with the error: "Software install failed! Incompatibility with current version. Please download the correct update package!" I downloaded the file from your link and confirmed the MD5 hash is correct. Did I miss something? I am currently running the OFFICIAL Nougat B360 on FRD-L14. Thank you.

Did you install the rollback image first from the Honor site? Not the full one, just the rollback package. Once you install that, then you can install the full package.

Are you talking about the rollback package here? Is this the same rollback for the L14? The description says it's for L04. http://www.hihonor.com/us/support/details/index.html?DOC_ID=92098
How do I flash this rollback image and in what order compared to UPDATE.APP?
I will research into this more when I get home from work tonight. Thank you!

I had an issue with this yesterday too.
If you still have access to TWRP, try deleting the data partition too. I think that sets it to a test mode than you can then downgrade.
From there I used the dload method to flash the rollback package, and then I flashed a full MM package.
I really wish Huawei would release a damn full Nougat image so we didn't have to do this each time (unless you really want to go back to MM)

I downloaded the rollback image except the instruction mentions L04. Is okay to install this rollback image on the L14 with 64GB? My phone was never part of Nougat beta and I don't have root. Never installed TWRP.
I just want to go back to MM because Nougat on my L14 has been a disaster on battery life. It also caused my audio to skip especially spotify when stream to bluetooth and I try to use the Internet.

Yup. Like I said, same issue. I have the L14 and that package is only for the L04.
I flashed it and seemed ok. Although I still think that wiping the data partition maybe had something to do with it.
Good luck either way!

I want to downgrade myself but don't want to mess up my phone. Huawei is really stupid of just putting the downgrade package only for the 32gb version of the phone.

Rollback image is Ok but don't download the full image as that is the one tied to L04.
I chatted with Honor support twice to give us a L14 image and they haven't done it yet. I would really ask you guys to do the same if you can as that will put pressure on them.

I have good news. The rollback image for L04 worked fine on my L14. After flashing that, I was able to install the actual update from your link. My phone is still identified as L14 and the 64GB is intact. My Android Pay is fully functional. Thank you very much.

Glad it worked for you!

I have the L14 64GB version and the downgrade was actually flawless. You will need to download the main update file per OP and also download the rollback image for the L04 from my prior post. It's a compressed RAR file so you can use 7zip to decompress. Ignore the instruction inside the file. My rollback went without a hitch but my phone is not rooted and no TWRP installed. Everything is stock so YMMV.
Create a folder "dload" in your micro SD card and copy in the UPDATE.APP from the rollback image. This file is about 67 MB.
Turn-off the phone.
Press Vol+, Vol-, and Power Button simultaneously until it turns on. Keep them all pressed until you see the update screen. You can release the buttons when you see them. The rollback image takes about 30-60 seconds to complete. The phone will reboot when completed.
The phone will restart back into Android. Turn-off the phone and remove the micro SD card.
Delete UPDATE.APP rollback image (67 MB) from folder dload.
Copy the UPDATE.APP file from the L14 image into dload. The file is about 3 GB after decompression.
Re-insert micro SD into phone and restart per step # 3.
The update screen will appear and it'll start to install the L14 image.
I believe it'll auto restart after completion (don't remember). The entire process should take 5-10 minutes.
Congratulations!!! Now you are back to MM.

I did follow your steps, but my keyboard has now vanished when the set up screen appears. It only shows google voice and I'm having trouble setting up my phone. Has anyone had the same problem. What can I do to get my keyboard back?

Sorry to bring this thread up again... I just followed this and got to B162 (L04), but my device is L14.
How can I start updating towards B385 for L14?
Anyone have any step by step instructions?

You need to make sure that the full update image (3GB) is already for the L14 version and not the L04.
In the second post in this thread there is a link to all the current L14 packages. In the list locate the one that has the version B162 and download it. Extract the UPDATE.APP and use that as the MM package for your specific phone.
Just FYI, the rollback image is branded for L04, however at that point it's only preparing the phone to allow to receive a update package that is of lower version than what you currently have (going from N back to MM). So even though you have the 64GB L14 version the roll back image will work regardless.
Once you are back to MM and your device is recognized as L14 once again, it should start taking OTA updates. This will get you back to stock N.

[Chinese]Question re: extracting 7.1.1 modem

Since the 7.1.1 update for chinese a2017 isn't full update file, can we extract the modem from it?
I want to convert my unit to US version using miflash method and I have already done this before but I get problems with signal even after flashing chinese modem from LOS thread by @Unjustified Dev. Although, this signal problem is quite specific with my carrier since I get a stable OS and signal using a different carrier/sim.
I'm thinking about doing it via twrp. Here are the steps I had in mind:
1. From b13, update to 7.1.1 via stock recovery.
2. after finishing setup of 7.1.1, I'll install twrp via fastboot.
3. back up everything in twrp.
4. miflash full b15 US version and twrp.
5. restore modem from twrp from my backup.
Do you think this will work? Or not, since B15 isn't 7.1.1?
Hopefully devs here can also share their thoughts. @ @DrakenFX @Oki @jcadduono
Thanks!
BTW, I attached a pic of what's inside the 7.1.1 update including the contents of patch folder.

Upgrade from 6.0.1 to 7.0 on A2017G stock

Hi, I am looking for help to get from 6.0.1 to 7.0 on my A2017G. I am currently on B10 with an unlocked bootloader.
This is what I have tried so far:
a. Route via OTAs and zips on sdcard:
a1. B10 with stock recovery. Android works. Got here from B9 with OTA B10 installed via stock recovery from sdcard (downloaded B10 OTA from German ZTE site).
a2. Updated from Android with the Axon7_Nougat-7_0.zip OTA on my sdcard (downloaded from the German ZTE site). Miflash completes without any error message.
a3. Result: phone reboots, after Axon splash screen, phone switches to edl mode (in windows: Qualcomm HS-USB QDLoader 9008).
a4. When I reboot to recovery, I can see that the recovery is 7.0.
b. Route via OTAs and N zip via adb sideload:
b1. B10 with stock recovery.
b2. In stock recovery, "flash from adb".
b3. On windows 10 laptop: adb sideload Axon7_Nougat-7_0.zip. Result: error message "* cannot read 'Axon7_Nougat-7_0.zip' * ".. Zip opens fine on laptop.
c. Route via TWRP and leaked Nougat 7.0:
c1. B10 with TWRP recovery, version 3.1.0-0-ailsa_ii.
c2. Flash ZTE_A2017G.Nougat_leaked_09_03_2017 BootStack and StockSystem by Tron1.
c3. Result: phone reboots to Axon splash and then switches to edl mode, same as a3.
d. Route via TWRP and complete fota update fota_update_A2017GV1.2.0B01_complete.zip
d1. Same result as c.
I have experience flashing with my HTC m7 but on the A7, it seems there are many more ways to make things go wrong and I have no clue where I am going wrong. Any help would be appreciated.
Some strange things:
1) my A2017G (bought in Germany via Amazon, it says A2017G on the back sticker) reports itself as a A2017U to my windows 10 laptop.
2) in stock recovery, when trying to flash from sdcard, I receive an error message that the A7 cannot mount the sdcard.

Replica - sorry

OK, it seems this thread finds lots of readers, so maybe someone can benefit from the solution that I finally found.
These were the steps I took:
a. Starting point was B10 stock (incl recovery) and unlocked bootloader, completely wiped.
b. Only way I could get the 7.0 update (downloaded from ZTE Germany) to work was by putting the .zip on a usb stick and using an OTG cable. Then, 'update' in settings found the zip and started to update. Result was v1.1.0B01
c. As soon as I booted into 7.0, it found the OTA for v1.2.0B02 and started to install that. So, I now finally have 7.1.1 stock with unlocked bootloader.
A big thank you to @raystef66 who provided lots of practical and moral support. Much appreciated.

Would you know what's the best version, Is the one you have now better? also do you know when you mess up the upgrade and your phone doesnt work can you still factory reset?

AFAIK, you can always do factory reset. There are some good threads with all the files you need such as https://forum.xda-developers.com/axon-7/how-to/download-center-factory-images-ota-t3606547.
Not sure what you are looking for, but I had good experiences with RR and AEX Nougat. I am currently on RR (unofficial version) N. Am just waiting for O to stabilize a bit to make the switch - see AEX thread https://forum.xda-developers.com/axon-7/development/rom-aospextended-rom-v4-3-t3618950 . I run nanodroid and microG in order to protect my privacy from google. So, no gapps, no google maps etc... .

Plz if you can explain step by step what can i do because i'm not good in these things , My bluetooth not workng , there no calculator , no software updater , i am not able to check if got update or not and so on......, im stuck plz help

Well hey.. first download this rollback package from this link:
http://download-c1.huawei.com/download/downloadCenter?downloadId=93645&version=371484&siteCode=np
Extract and move all the files to dload folder on your external SD Card then install it with the 3 button method. If there's no dload folder then create one.
So the phone will reboot and now you can downgrade to any mm rom
Now just download this mm rom from this link:

And again extract and move the files to dload folder on your sd card.. Install with 3 button method.
Done! Everything should work now!
In case If you don't know what the 3 button method is..lol
•Power the phone off ?
•Just press and hold on POWER + VOLUME UP + VOLUME DOWN buttons
The phone will start installing the rom and that's the 3 button method ?❤

this is not working for me. it says incompatibility with current version and to download the correct version.

Man, you have to do entire procedure: unlock bootloader, install twrp for Nougat and flash oeminfo for your phone. Before that you have to put in dload folder MM firmware (B130/B131),
because after flashing oeminfo phone try to repair firmware from dload folder. If repair do not start, power off phone and power on with 3 keys combination.

Hi All,
I'm having a similar issue as lennie27 however I think I might have strayed down an incorrect path during the process of upgrading to Nougat. My device shipped with VNS-L31C16B120 with no updates available through the stock updater. I tried the Firmware Finder guides which listed options for VNS-L31C169B13x and VNS-L31C432B13x however none of these updates would work, updater would say it's incompatible with current version. I also tried manually downloading the VNS-L31C432B160 firmware and installing that with the 3 button method as well as the EngineerMenu option with the same result (found guides that stated needing to be on B160 or B161 before making the jump to Nougat). Eventually I decided to unlock the bootloader and install Nougat through TWRP and followed the obeygeekupdate-huawei-p9-lite-to-android-7-0-nougat-manually guide (can't post links ) on manually installing Nougat (stupidly never paying attention to the fact that it's a beta build guide). I've installed TWRP to the device again using the P9 Lite Toolkit v0.0.0.11 found here on XDA (used this when on MM however the upgrade seemed to restore the stock recovery) with the idea of downloading the build from the ministryofsolutions huawei-p9-lite-vns-l31-nougat-b371-update-stable-europe page and pushing that to the device instead (however now the device doesn't want to boot into recovery)
Now my only concern is, will this work? I've noticed a bit of commenting going back and forth on the ministryofsolutions site which essentially boiled down to the need for debranding the phone (apparently C19 is MTN South Africa specific and I need to debrand it and get it onto C432 Europe before mucking about with Nougat, but alas to late) which seemed to be something I should have done while on MM still. If I can find a full firmware link for VNS-L31C16B120 can I flash that through TWRP without needing to follow any prerequisite steps? So far nothing that I've tried to flash using the three button method has worked, I'd just like to get back onto an official stable firmware again.
Any advice will be appreciated

you need to install nougat recovery, not the one from the toolkit. then twrp will work and the device will boot.
to go back to 120 you need to install oeminfo, and then the update.app

Thank you for the reply, managed to come right a few hours after posting. Turned out the copy of TWRP that I had on hand was more outdated than I thought, downloaded the newest copy and that worked on the device. Additionally I managed to find a website listing just about every firmware for the phone (Including my original MTN ZA specific variant) so I downloaded that and managed to restore the phone using the three button method. Phone is back to stock now and even the unlocked bootloader nag screen is gone so I'm guessing the bootloader is locked again as well One day when I'm brave enough to attempt this again I'll look at debranding the phone and getting it onto a C432 based ROM before getting it onto Nougat again.

roll back to Oreo? What are you running right now then?
If you mean roll back to Nougat then yeah, just download the official b35 package, get the update.zip from inside the zip, and put it in the root of the internal storage, then go to Updates and it should appear
If it doesn't put it in an SD card and install it from the recovery
Also, G Oreo probably has support for your language, if you want to stay on stock+ firmware just flash oreo B03 from the G, but remember to flash the U modem

Hey, I'm having the same problem when I try to roll back from Oreo. I tried putting the update.zip in both internat and external storage but the updates just fails, even from recovery.

Try enabling USB debugging, I don't recall if it was needed or not for the recovery update but it might be. If it fails you'll have to go EDL Tool, simply get it from the ROMs, kernels, development section and also download the B35 EDL package from there. Flash the package and you're done.
