I'm trying to downgrade from 9.1 to any version that allows a bootloader unlock..
I've got a (P20 Lite) (64gb);
ANE-LX1 build 9.1.0.231 (C782E5R1P7)
EMUI 9.1.0
I believe that the C782 refers to the fact it's a UK version and ProjectMenu verifies this:
Vendor: o2
Country: uk
I tried downgrading via HiSuite, except that it gives me no options to downgrade and simply states that I'm up to date.
I also tried putting various firmwares into a dload folder and install via the ProjectMenu sdcard update
as well as a forced update (holding +&- and power whilst booting).
Both methods failed....
I've only used firmwares with 782 in them i.e
Huawei P20 Lite ANE Anne-L21 8.0.0.143(C782) Firmware Android 8.0.0 EMUI 8.0.0 05015EHQ androidhost.ru
or
Huawei P20 Lite ANE-LX1 ANE-L21 Anne-L21 8.0.0.150(C782) Firmware 8.0.0 r1 EMUI8.0 05015EHQ androidhost.ru
I noticed the firmwares were (vendor) hw and (country) eu, maybe this is why the updates are failing?...
I believe there is a way to change the vendor & country to match on the phone to match the firmware I want to install, but I couldn't manage that either...
What am I doing wrong?
Can somebody please verify that I am (at least) using the right firmware(s) or that I could try other firmwares?
Any help/guides greatly appreciated
Thanks
cant help much, but, you can try region change thing from dc unlocker region vendor cange info
here are first site i find at dc unlocker repair info
have not tried with p20 lite, but used with p9 and all worked, ofcorse, there can be driver problems if use windows 10, so, turn off driver signature before instal some drivers related!

Thanks for tho reply and the links & tips, I 'll have a look through them.
I'm pretty sure the drivers are installed correctly as I can communicate over ADB & fastboot. I'll double-check anyway

Hello.
Some time ago I assumed a topic about the brick of my phone, Mate 10 Lite, I managed to bring it to life through the dc_phoenix program. The only version of the system they had was EMUI 5.1.
I'd like to have 8.0.0 to install LineageOS. But I do not have the code for the bootloader, dc_unlocker and HCU shows that it does not detect the phone. HWOTA needs this code to update. Is it possible to get this code somehow differently? Thanks for the help.

Are you sure you enabled Manufacture mode?
Also, phone needs to be booted, not in fastboot
Edit; you might have to install drivers for it, they have a button in HCU/DC named Support or something, that will open a website with drivers and such. I can't remember exactly which one I used because there was 10 or so to choose from. I think it was the most recent anyway. After you have got unlock code you'll have to uninstall driver, it breaks MTP support.
Edit 2: it's named Huawei_Android_phone_drivers_2.zip and location is Other downloads / Drivers / Huawei / Phones
But you need to open Support Area link from DC/HCU, it won't let you download if you're not logged in using the program
Hi, another fool here who’s bricked their Mate 10 Pro! Will DC Phoenix will help?
I was attempting to de-brand the device and things were going well (flashed numerous Pie firmwares) but then I attempted a downgrade to Oreo and, like others have found, this bricked the phone: the update failed and rebooted to fastboot with a black screen.
So the phone's stuck in fastboot but Windows can see the device via fastboot and so does HiSuite (but HiSuite claims no recovery options are available.)
I have the device serial number, IMEI and numerous firmwares (inc BLA-09 Board Software). Bootloader is locked.
Do you think paying for DC Phoenix will help? :fingers-crossed:
Thanks

You will have to use test point, so this requires you to remove the back cover and short the test points.
It's not an easy task, but you can find some guides here on the forums.
Update: Took the phone to a local Huawai approved repair shop and they fixed it! They also de-branded it for me.
This is probably in the wrong section but this ismy first time on this site.
So basically, i'm trying to root my phone but to do that i need to unlock the bootloader, and to do that i need to downgrade my p20 lite to android 8, because dcunlocker doesnt work with android 9.
I've tried connecting my phone to hisuite and it shows that it is recognised but the prompt to allow the connection doesnt show on my phone. I know i've seen before but i cant remember what i did.
Also ive tried to manually downgrade my phone, but it keeps saying update failed so ive given up with that one.
If anyone could help that would be deeply appreciated. :good:
Device specs:
Huawei P20 Lite

EMUI: 9.10
Did you tried HCU ?
I would appreciate anyones help. I have a Huawei Mate 20 Pro Model LYA-L29. When I run the commands it tells me this about my Firmware Version:
VENDORCOUNTRY: HW/SPSEAS
BASE VERSION: LYA-LGRP2-OVS 9.1.0.357
CUSTOM VERSION: LYA-L29-CUST 9.1.0.11 (AUSC636)
OEMINFOREAD: LYA-L29-PRELOAD 9.0.0.1(C636R2)
I want to upgrade to EMUI 10 but whenever I try using HiSuite, HiCare App on Phone it says my version is up to date.
Is there any way to upgrade this phone? I have not unlocked the Bootloader because Huawei is not issuing Codes to do so.
I'd appreciate anyones help with this.
Thanks
i have the same problem
Hello, same issus here
1st thing i would try is to contact huawei support chat.
now the more extreme diy method may break safetynet and stop things such as google pay from working. if you decide to try it, you have been warned.
you can manually force an update through USB OTG.
there is a thread on this forum called "How to update Huawei Mate 20 Pro With Locked Bootloader"
it has the information you need to get it to work.
for the greatest chance of success, you want a firmware with the same cust/preload region as yours
(in the case of the OP this would be C636R2)
note, this can only be done with full firmware files, not updates.
you can use an app called "firmware finder for huawei" (play store) which you can use to find and download the full firmware file.
also, forcing the incorrect firmware will brick your phone. very easy to get confused and try to force a firmware meant for another model completely.
theoretically L29 and L09 variants should both work, however your dual sim functionality might stop working.
I did this sort of thing last year and haven't looked at it for a very long time, just giving some info which may get you on the path if you wish to try the diy method.
ANyone tried? how was it? does it work

Hello guys!
I need your help to solve a difficult problem.
In August I bought the Honor 9X STK-LX1 (431) from China.
The device came with Android 9, firmware 9.1.0.334 and security April.The device booted every time with the Honor logo screen and worked normally.
After a few days, I tried to upgrade the software manually via microsd card, using the dload method. I got a softbrick. The device was started, displayed a Huawei logo screen (not Honor logo) and stopped there. Again and again.
I tried many roms for Honor 9X STK-LX1 (C431) but none worked. Hisuite did not recognize the device, adb-fastboot did the same. I also tried eRecovery, it connected to wifi and then it showed "Get package info failed".
After many attempts, now the device is functional, without a keybord installed, but it isn’t a Honor 9X-STK-LX1.
Here are some screenshoots:
I don't know what to do, to restore my phone with the correct firmware....
So we fixed your device.
Honor9x STK has many hardware variants.
It seems yours was STK-L21A hardware variant and was branded Honor STK-L21HN C431 hw/eea.
Problems we got were:
- For your cust region and hardware variant, there is no honor STK-L21HN Emui10 dload available yet, only Huawei STK-L21.
- latest approved LGRP4 B199 online package seems corrupted (CRC). (We did not tested with previous LGRP4 builds)
- LGRP2 online packages are intended for STK-L21A OVS branded Huawei and not Honor.
So, in the end, rebranding your device from STK-L21HN to STK-L21 just did the trick to finally fix your device.
I had to use paying remote softwares to rebrand you and force flash a correct firmware.
With the help of @oslo83, we managed to make the device functional.
Now it works like a charm.
It was not easy at all and oslo83 tried
very much.
I want to thank him for his interest and help.
