Hello everyone.
Planning on installing OpenKirin ROM on my BKL-L09, i have to downgrade to EMUI 9.0.
Problem is HiSuite doesn't let me go lower than 9.1. I then wanna ask you guys if a downgrade on 9.0 was possible.
Will the 2018 security patch make it impossible ? Is there a way even to do it ?
I know forcing HiSuite to install 9.0 is a bad idea, because i tried installing 8.0 which bricked the device entirely. I had to buy a service to reflash the stock rom.
Bootloader is unlocked.
Have a nice day, guys. Take care of you.
@Soriahz Can you please post the procedure to downgrade from EMUI 10 to 9.1? I am unable to do so on my BKL-L09.

Simply plug the phone while being booted in Android to your PC. Launch HiSuite and go to Software update. Click then on the right part which is called "other versions". You will then have the 9.1.0 update available.

Hello! I am fairly new here and am wondering if anyone has download link for the COL-L29 8.1.0.120 (c636) update for Honor 10. If there was already a thread about this, kindly redirect me to that one. Thanks a lot!

There 3 files but you may need to flash only 2 manually for update to .120 build. you need to use dload method to update. There is a guide in my signature on how to use dload. You can skip till download step and follow rest.
Why you want to update manually by the way.
Also, you can use firmware finder app or their website to check for firmwares.
Thanks shashank1320! I really appreciate it. I am having troubles with the latest security patch. I guess I should rollback instead of getting Android 9.0 and EMUI 9.

What is your current version?
8.1.0.153
Hey,
Altough I bet there are hunderds of threads like this, I decided to create another one
So because I have my mate 10 lite around 2 years (a bit less), I would like to get an upgrade. Sadly I won't get Android Pie officially, so I'd like to install a custom ROM.
To do that I need an unlocked bootloader which dc-unlocker is only able to do below Android 8.0.
So I would have to downgrade my Android 8.0 (Btw, EMUI is also 8.0) to Nougat 7.0.
The method through HiSuite didn't worked since it just says "Newest Developer Version installed", but nothing with "Switch to other versions".
Also through Firmeware Finder (Playstore App) it doesn't show me the option "In-App Proxy", so I guess it doesn't work either with that.
Is there another way to do, if so I would really appreciate any help
Thanks in advance
My Mate 8 also keeps on Android 8.0, without any update to Android Pie officially.
If the official utility, HiSuite, which is developed by Huawei doesn't work, we maybe have no way to downgrade the system software on Mate 10 or Mate 8.

It all depends on your current build version. If I remember correctly the ability to use DC was patched in most custs in May or June. So if your security date is prior to May you can still use DC. If not you're out of luck. You can use testpoint to flash board software and then get unlock code through there, but it requires you to remove the back of your phone which will break IP rating and void warranty (If it's still under warranty)
Hi,
i had some issue's with Android 10 so i tried to downgrad back to Android 9...used Xperfirm to download 55.0.A.10.26 UA
but after flashing there was no Compas or Gyroscop function anymore....not even available at the service test menu (*#*#7378423#*#*)
so i flashed latest Android 10 version again and all is working well...any idea's how this can happen
or another source for the Android 9 (55.0.A.10.26) to download.?!
thx for any support :good:
Perhaps trying a different version of Pie?
By the way. does twrp work for you after downgrading?
newer flashed twrp
tried couple versions of Pie (EU, UA and play PL) not one brought back the sensor (gyroscope) back
updated OTA and with first update to Android 10 sensor started working normal....like a miracal.....Sony did something at the backround on our devices for sure....like deleting some function key's
so if u like to downgrad new devices u'll lose function's like u lose on rooting your device
Thanks! Good to know
i red some guides they said u need "OEM Unlock" to downgrade.!?
did anybody a succesfull downgrade from Android 10 back die Android 9 Pie

Hi, I currently have a Huawei Mate 10 Pro (BLA-L09) running Android 8 compilation OS 8.0.0.137(C605), I want to update to the latest version available (Android 10, EMUI 10) but when I go to the Update tab it says that is on the latest version. I want to use the HiSuite-Proxy metod to force the update but i need some help:
- I cannot find the update.dbankcdn.com files (Package URL, CUST PKG, Preloaded PKG) on the web for this phone, do you know where i can find them?
-Apparently if I want to install 10.0.0.xxx I need to install 9.0.0.xxx then 9.1.0.xxx first, so i need to install Android 9 first, is that correct?
Can I get some help? Thanks!

[URLS] Keeping Track Of EMUI 10
So as some of you might know, Huawei has officially announced that EMUI 10 is going to rollout early/mid/late June, I've built a quick app which lists the latest EMUI 10 uploads of Huawei, I'm going to post them here so we could stalk on what...

需要恢复官方系统并使用华为移动助手进行升级
Hello, I have the BLA-L29 9.0.0.197(C432E4R1P11) than I received via OTA the .246 .From that no more even if Huawei approved and pushed OTA till 10.0 (C432). If I downgrade to 9.0 (C432) and not (C432E4R1P11) can I update till 10.0 ?
Hi everyone.
Hello, i've just got a Huawei P20 Lite ANE-LX1 with EMUI 9.1.0.381 from a friend. It's my first Huawei and since i am usually running my phones with custom roms, i want to install a custom rom to it. Usually i am trying to get phones that have a reasonable unlock process but this was a gift and i thought it should be possible to install something anyways.
After spending hours into this and reading allot of posts on this forum, i am not eager to open up the hardware and go this potatoe way. I've watches some Youtube videos about the process and i am not sure, if i can manage to get the phone back together. So i was trying the other way with downgrading EMUI to 8 using dload method in order to run dc-unlocker. But somehow i am unable to do so. I am always ending up with "incompatibility with current version" error. I've tried using the dailer code menu, as well as the 3 buttons method. It's not working at all. I've tried multiple versions from androidhost.ru for this phone. There were no options to downgrade to any prior version using HiSuite as well.
Can someone help me to unlock the bootloader for my phone?

If the rollback option is not available with your HiSuite ("switch to the older version" or "Earlier version"), you must downgrade to the lower EMUI 9 build version number doing the dload method (flashing Service ROM ). What is your region? (Cxxx in build number).
Btw, it's impossible to downgrade to the lower EMUI version via dload method.
Hello, thanks for your reply. My current build number is C432E7R1P7. I think i figured that i should use C432 versions but i haven't thought about using another 9.x version and instead go straight to 8.x. Is any lower 9.x version ok?

On EMUI 8 (in order to run dc-unlocker) you need downgrade to .126:
Link
With .126 you should be able to use dc or hcu-client .
Thanks, you've helped me allot! I've got it working and have the bootloader unlocked. Going forward, i was reading your LOS 17/18 thread. I could add a comment there but since we are writing here now, i am going to ask here:
I am still with EMUI 8. Is it actually needed to install another version of EMUI in order to install LineageOS? Isn't it possible to just install TWRP and go on from there?

LOS/LiR requires emui 9.1. Do not install the latest version, flash 9.1.0.200 via dload.
Finally made it and finished installing LOS. Thanks again for your help. I've marked the thread as solved.
No problem .
