How to revert to AL10 from BND-L21 with no unlocked bootloader? - Honor 7X Questions & Answers

Hello,
I have a Honor 7X BND-L21 bought from Aliexpress.
The phone's firmware was updated from AL10 by the seller before shipping.
I'm basically trying to get a bootlocker unlock code from the Huawei website but the site doesn't give anything after filling in my details.
I was wondering if it's possible to revert back to AL10 without unlocking the bootloader? I want to check if I can get an unlock code after reverting back to AL10 as it's the original firmware.
I've tried firmware finder and it shows there are new updates available but every time I try to install the latest update it fails for some reason.
Looks like I'm not getting OTA updates since I'm still on a security patch from October 2017.
Thanks!

If you download the dc- Phoenix tool you can flash what ever firmware you want with a locked bootloader or not the only thing is it cost 15 euros but it's worth it you get the tool for 72 hours

XT1635-02 Rom on XT1635-03

I intend to buy the chinese variant XT1635-03 at Gearbest. Is it possible to flash the XT1635-02 rom on it or will I be stuck with the chinese rom? If that is possible, would I receive the OTA updates?
You can flash the every rom you like i have the Chinese version and i flashed the Russian rom on it you just need to unlock your bootloader

Thank you very much. Your answer was decisive for my decision on buying the device, and I think the chinese version comes already with the bootloader unlocked.

It's not a big deal, as long as I can flash the latest roms.

Sorry to bother again, but did you flash the entire rom? I read at other thread that it is dangerous to flash modem, fsg and bootloader from another variant.

I read on another thread that he flashed a -02 firmware without the modem files and no partition wipe (64 vs 32 GB).
Is there a full "HowTo" to go from XT1635-03 Dual-SIM to a XT1635-02 Firmware? Of course, Dual-SIM should still work afterwards. OTA will not work in any way, right?
Are there custom Roms which can be used on the XT1635-03 ?
Thanks
i have a problem

I can not unlock my bootloader with the code of the bike my pc does not even recognize the device in fastboot, it only recognizes as an idle device called fastboot addison s. you know what to do?
Any progress to what can be done with the chinese moto z play?
Hi,
I got Moto Z from gearbest too and it also comes with ADDISON_CHINA_CUST image.
I was able to unlock bootloader with 'fastboot flashing unlock' and then I flashed it to retail 7.0 (via fastboot), then updated successfully to 7.1 (via adb sideload).
Unfortunately it still shows retcn channel and ADDISON_CHINA_CUST as baseband.
Is there any way to change it too?
Thanks!

To be short: no, there is no pracical way to change the software channel and modem version (they are tightened to hardware)
I do no think you receive any OTA but if so do not install them

Thanks for your reply! Sounds like buying a phone from gearbest is not a good idea if you want to receive OTAs and stay with official ROM.
One more thing: after I updated the phone to 7.1 it shows during startup 'ID: bad key' (apart from 'Your device has been unlocked and can't be trusted'.).
When being flashed, it also returned:
writing 'boot'...
(bootloader) Image signed with key bad key
and
writing 'recovery...
(bootloader) Image signed with key bad key
Btw, maybe it's a stupid question, but is it justified to consider retcn channel and modem version (ADDISON_CHINA_CUST) as kind of backdoor? It still not official software (or at least the latter)...
hi
Hi,
I received a Moto Z Play from Banggood as exchange for another phone under warranty.
I unlocked the bootloader, and via fastboot with RSD lite I updated to nougat 7.1.1
but the chineese version fot XT1635-03. I got it from here :https://mirrors.lolinet.com/firmware/moto/addison_cn/RETCN/
This rom is much worse than the original one, it's a chineese rom with only chineese and english language, no play store, no googleapps, no chrome...
At this time, I don't find the way to flash another Rom.
edit: repaired flashing another 7.1.1 custom rom

If you install the Verizon version your device will update automatically
My bootloader was already unlocked when I got it from banggood, which is similar to gearbest.
Install this via rsd lite and you will have updates via ota:

Anyone know if it's possible to lock the bootloader of -03 using -01/-02 ROM?

Honor 7x BND-L21 downgrade issue

Hello, more than a month ago, I updated my phone on emui 8.0 using the official beta program. I would like to return to emui 5.1, but when when I try to flash the FULLOTA file (UPDATE.app) with the official recovery, it fails and gives me an error. So I thought to install the rom with twrp, except that I do not find how to unlock my bootloader. On the site of emui, there is no more the page to unlock it by receiving a key. I would like to know if there is a solution to return to emui 5.1 without unlocking the bootloader, or if there is another way to unlock it without using the official site.

Both of you guys above to fix your phones the way I know of it's going to cost 15 euros I have done it And it works with locked boot loader or locked frp in fastboot mode you can revive your device flashing the update.app from a stock ota the tool you need is called dc-pheonix and you can find it on dc-unlocker.com just Google that if you want to fix your phone the total cost is less than 20$ and you get the tool for 72 hours as of now it's the only way hope it helps you

Thankyou for help but those files are actually for BND-L31A185
I have BND-L31C185
and in that list there's another firmware with build no. BND-L31C185B302D001 but the phone I have is D002 variant so it is not gonna install through local update in my phone..
I need a procedure to convert from BND-L31 to any other variant that has OREO update.

Don't follow these steps, I'm just making rough outline, not guide steps.
In order to change or convert from L31 to other model, you will need to unlock bootloader, and install twrp, then flash other model oem-info.img (believe it needs to be edited or you you might loose imei).
Then after oeminfo is flashed, flash other device firmware.
When you have done all that, you could have done safer steps, and instead of flashing other device oeminfo, after unlocked, and twrp. Flash FullOTA I linked with hwota.

Unable to update BND-L21C432

G'day,
I bought a Huawei Honor 7X from JKteam on Aliexpress but it's not receiving any updates.
I was able to update to version B102 through firmware finder but can't update to Oreo through there because the download keeps failing.
I've downloaded the firmware from Team MT and put the files on an SD card as per instructions but the update fails after 5%.
I am not able to unlock bootloader as I can't get a code through the Huawei website either, I've contacted Huawei support but they're useless.
I have also opened a dispute with the Aliexpress seller as this is not acceptable.
Does anyone have any other suggestions to get the latest updates?
Thanks.

Bootloader Unlocked L29 C636 owners please help

Question for those of you on L29 model w/ C636 region.
I purchased a bootloader unlocked EVR-L29 from a forum member here but don't want to bother him with more questions.
QUESTIONS:
-I am on version 9.0.0.7 I have tried manually updating within the phone itself but it says I am on latest version.
I downloaded latest HiSuite program on laptop and connected the phone to it using usb debug in dev mode. Still says on latest version. I have attempted to go into erecovery & force searching for an update. Which sorta worked but it just downloads the current version I am already on.
So I am guessing I am having these issues because it is bootloader unlocked?
I am guessing you bootloader unlocked guys have an alternate method of forcing an update?
If there is an alternate method I can use I am guessing it is best to incrementally update instead of pushing the latest build?
-Once fully updated to the latest build will the old root method still work on EMUI 9.1? Where we flash a recovery ramdisk as shown HERE?
If the answer is yes do you all flash a stock recovery ramdisk for L29 or a patched recovery ramdisk? What is the difference?
I unlocked the bootloader on my L29 and was on 9.0.0.208 and couldn't get the 9.1.0.300 OTA update until I used e-recovery to download and install 9.0.0.207. Once I did that the phone immediately received the 9.1.0.300 OTA update and then patch #1. I haven't rooted yet so I don't know if root survives the update. It might because the update didn't wipe anything.

Yup erecovery just keeps downloading and installing 9.0.0.207 and when the phone reboots I get no OTA. Odd. I'll try putting the sim card in to see if that helps since I'm using wifi
Update for any people in the future that have this problem.
NO METHODS WORKED except Dload method. Finally on .310 update.
