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:

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 .

In XDA-Developers every code builders finding solutions for Mate 9 but there is nothing for Mate 9 Pro (LON) versions.
I am opening this thread if someone give a hand to resolve downgrading problem Oreo Beta to Offical Nougat.
In Mate 9 forum @mankindtw build HWOTA 8 solution for MHA versions. Probably people will suggest me to use FunkyHuawei thing. But PayPal and BitCoin payment methods are not working in my country because of acredition at banking system.
So if any developer can support M9 Pro, it's too much appriciated for me.

It's possible while you are in stock recover via Firmware Finder. Just you need to find which stock ROM works for your device. None of Rollback Roms worked with me.
Yep! I'm also waiting for this! Hope a solution comes soon

Probably @mankindtw preparing a solution. He made the old HWOTA system and nowadays keeps silence. It's my guess, waiting for the official ROM release date.
@duraaraa I have a spesific problem. I'm using Huawei Mate 9 Pro. Bootloader unlocked, Oeminfo file belongs to orginal LON-AL00C00B225 but system running under Oreo 8.0.0.323 C636 log. It is sometimes running and sometimes don't.
I tried to downgrade Oreo to Nougat but it wasn't possible by Firmware Finder (special thanks to @gmanrainy for kind interest) or @mankindtw 's solutions. Probably file structure is different on Oreo, that could be reason for not downgrading.
Anyway, I know you are also moderating FunkyHuawei webpage. Is it possible for my situation to rebrand C636 and install LON-L29C636B235 version? Your payment methods not working in my country so I'l figure it out somehow. But I clearly wanted to learn if it is really work for me.

Yes, it's possible. But I would need to look into which package you need to install. You'd probably need to use FHRebrandTool to fix the branding correctly.

It's not problem to use it. I already downloaded tools but looking forward for your answer. Thank you.
I successfully rebranded my phone to LON-L29C636 via your stock OEMINFO file. Now phone is in bootloop.
I am really wondering that is FunkyHuawei able to install B235 Nougat firmware. I'll share all details who are looking solution to downgrade Oreo to Nougat.

You'd need to flash the Oreo firmware with FHUnbrickTool if it's not booting. Or you can re-unlock the bootloader. Probably issue is you used the tool with unlocked bootloader and a modified partition somewhere, I'm guessing.
You might also be able to use eRecovery method with Android O firmware. Downgrading to N will need to be done AFTER you have it booting in Android O.
I can't monitor this thread well, so you should email FH support if you need help.
EDIT: I apologize. I thought you were using FH tools. Apparently not. Yes, FH can fix your phone, to answer your question from before. There is no other solution for M9Pro right now.

I wrote an email on 23th but there is no answer from FHteam. Anyway my phone now is totally bricked. Opening in error mode. Error no 13 with no image. As you know I tried to downgrade from Oreo to Nougat.
Can we fix it and install the original Chinese edition on my phone? No problem if it would be Oreo or Nougat.
I'm going to try to buy credits from a different way, because PayPal is not working in my area.

@duraaraa I want to thank FunkyHuawei team for responding very fast this time. We were online together.
I think my device hard bricked and I'll try everything to access fastboot mode. I always have bootloop and error mode continously. Key combinations don't work. Only power key, but it doesn't shuts down the phone, it always restarts. I was really expecting a downgrade solution from @mankindtw like he did for Mate 9 before. But he didn't and now device is hard bricked. Before an Oreo installation they need to warn people about there is no return.
No problem. I believe we will save my M9 Pro together. Thank you in advance and I'll stay in touch.

I had neccesary testpoint and get board firmware. There is no problem anymore but anyway thank you in advance brother.
I used Firmware Finder and it did the job. I downgraded from LON-L29C432B368 to LON-L29C432B229. You need to select FullOTA-MF-PV version.
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've ordered an A10 for my wife. If it comes pre-installed with Android 10, can I downgrade it to Pie so I can install a GSI rom from @phhusson?
TIA
If they are the same bootloader version, you can. If not, you can't. If you don't know how to tell what bootloader version you are, I suggest you use Google.

Thanks for the quick reply but now you've really confused me! If the phone arrives with Android 10 on it what am I comparing against? And if it comes with 9, is there any way to check the bootloader version of the 10 upgrade before I install it (don't want to be stuck on a version I cannot root <g>)
I haven't had a Samsung for over 10 years (S2 - fabulous phone) so I'm a bit out of date. Is the bootloader version still the 5th character from the right in the baseband number?
TIA

Well, first of all I don't know if Android 9 is available for your phone or not lol I don't have the device. Maybe it does, maybe it doesn't. I suggest looking at sites like Sammobile to see if there is Pie for your phone
And second, yes that's how you can tell the bootloader version on Samsung phones still
Thanks @ShaDisNX255
Good news - it came with Pie not 10 and the bootloader is v3 so I should be good to go
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.
Hi, I'm looking for a way to install gms on huawei p50 series European version, especially p50 pocket. I tried several methods, but all require or a downgrade, quindo you must necessarily own a p40 series or in any case in previous model that has come out of the factory with previous versions of emui, or a Chinese version of the device with harmony OS installed is required or finally to convert your device to a Chinese version, but for this procedure a downgrade to emui 11 or 10 is still required, which as mentioned before is impossible for the p50 series. Obviously huawei does not provide codes for unlocking the bootloader, so I am looking for an alternative way. As soon as a method for installation is found, it will be posted here. If you have medotes kindly post them
As far as I know P50 x started with EMUI 12. That's why you will not find a ROM to downgrade.
It seems that there is a custom ROM out for the pro but not for the pocket.
I just made another thread in this subforum to ask if someone can confirm that P50 harmony OS checks the phone model and refuses to run on the global version. Otherwise looking for HarmonyOS stock ROM and installation via TWRP could be an option.

The basic problem is that huawei does not allow unlocking the bootloader, not providing more codes since 2018. If you know alternative methods to unlock the bootloader, then install twrp and flash rom, you could write them here and I will be happy to try them
I state that I'm looking for solutions for native installation of gms, so 'gspace' or other emulation apps will not be good

How can I convert my p50 pocket eu to Chinese version? I tried several methods but with poor results
I think it's not possible for P50x.
It appears that in opposite to P40x they check now the smartphone model so that China ROM won't be available to install for an EU modell.

Yes, I knew. To convert the smartphone to Chinese version you need to downgrade to emui 10, which however you can not run on p50x as their factory os is emui 12.
That's why I opened this discussion to search or work on medotes for the native installer of gms on p50x eu.
Thank you for your reply.
