Hi guys
Someone has succeeded with downgrade from oreo to nougat ? I need go to huawei service, to exchange the display, but problem is "relocked bootloader"
So many tutorials here, which to follow for downgrade and have "locked bootloader" ?
You can use HiSuite or install the downgrade firmware through Firmware Finder. It has the normal Nougat version, but in the description it tells that it downgrades.
HiSuite tells me that I have the latest version so.. I cant downgrade from HiSuite, or if i can tell me how to do it please
@yungshadow
As M1chiel said, try with Firmware Finder.
Remember!! Everything is on your own risk!!
Don't know which version you have, but for me this is the roll back firmware...
Let's try. But.. still 0%
If you use proxy option, you have to set proxy in WiFi settings.
localhost and 8080
Then start download and wait until 4-5%, then disable proxy and continue download.
i'm using DNS. Now 11% XD
ok i'm finally have emui 5. Now i must rebrand ?
That I don't know, I already didn't understand why you wanted to downgrade ??

Can't do anything with this trash device, even TWRP fails to install. What a waste of money!

I need to have bootloader status "locked" not "relocked" so i must rebrand to l09 and back to l29 yeah?
Ok guys
I Found a solution.
1. Downgrade from Oreo via FF using B185 (downgrade firmware) thanks
djg269 said:
2. Download some L09 firmware and install via FF
3. After installing I had bootloop (huawei logo, booting system for 10-15 sec and still restarting)
4. Enter eRecovery VOL-UP + POWER > Wipe data and cache
5. After Wipe phone said it's still L29 but now bootloader is locked not relocked
So i'm done now

I have a small question - in FF it says to make sure my current version is not "unlocked" - does that mean the bootloader or...? I just want to downgrade to B180 so I can install HuShed. I'm on L29C432B360 currently.
I don't remember this information. Could u send here Screenshoot with that dialog from FF ?
Same screenshot as post #4 -> https://forum.xda-developers.com/showpost.php?p=76556011&postcount=4
I used b185 from b360 with unlocked bootloader and I had no problems.
You should use b185(rollback firmware) and after this will be able toinstall whatever you want
Alright, last question - I have TWRP installed for 8.0. Will this affect the downgrade somehow? Because for example I can't install OTAs with TWRP. I'm sorry I'm kinda new to these kinds of stuff.
I didn't have installed twrp for 8.0 when i Decided to do downgrade so I think it doesn't matter but you can flash stock recovery for 8.0 if u want ofc.
Now i'm on 8.0.0.365(c432) but with official OTA update
Hello, some procedure or guide to downgrade a p8 lite 2017 dual sim (PRA-LX1), all stock looked, actually in BETA Oreo 8.0.0.321 (C432log) to official Nougat?
- I have used Firmware Finder but all rollback firmwares are not aproved for my IMEI, and the aproved not explicit rollback firmwares causes error (i supose dont format or create partitions to rollback)
- Hisuite, dont show option to rollback, in update, always display i am in last version. And the option of restore in fastboot ends with a your device not support restore.
- In erecovery the option to download last firmware a recovery, conects to wifi but always error when download.
Remenber, i am full stock, no twrp, no unlocked bootloader, or frp, etc,etc.
Can someone helpme, or the only solutions is wait for new Oreo oficial update or some milaculous aprovation for me imei in rollback firmwares?

I have tried it several times and I have never been able to update to pie using the erecovery method.
I have a Huawei P20 Pro, CLT-L09, C432.
I haven't received the Android 9 update, I am stuck on 8.1.
I found a stock rom, just not Android 8.1 but 9.
I don't want to unlock my bootloader. Can I still flash this ROM somehow?
No, and there's nothing that you can do unlock it.
But you can update manually via dload option.
Im using the same model and its working great also gets ota after manually update to emui 9.1
Can you help me with that?

I created dload folder, and put the ROM in it. Got the code in dialer, selected software upgrade then sdcard, but my phone just says No sdcard.
Can you please help me with that?

You don't need to unlock your bootloader, you should be able to use firmware finder and hisuite to update, search for it, there are quite a few threads.

Well yes, I should be able. But I am not. I am hungarian, and the Huawei support informed me about the device being Austrian. I bought the phone second-hand, me and the seller neither knowing about it.
And they cannot update it unless I bring it to Austria.
OTA not working since I am 380kilometres away from Austria. HiSuite neither, HiCare neither.

Or is there a way of installing the ROM manually with HiSuite?

ROMs no, it's a full ota or nothing I'm afraid.
Why won't firmware finder and hisuite work? Ask in their thread.
Hello everybody,
Can i downgrade my P30 pro vog-l29(c815) form Android 10 To Android 9?? Using OTG dongle (recovery mode) , considering that i have the Firmware.
Thanks in advance for your reply.
Later Edit:
I have successfully managed and figured out how to downgrade using Hisuite for PC.
I was on EMUI 10.0.0.90 (this is the last Ota update I have received, in order to get the (switch to earlier version button) I downgraded my EMUI FROM 10.0.0.90 to EMUI 10.0.0.186 USING dload, after that I enabled hdb and installed Hisuite on my mobile and checked firmware update button through it, and boom now I got two buttons, Update to EMUI 10.0.0.90 Again which I don't want to and switch to an earlier version which I did and successfully downgraded to EMUI 9.1.0.244 (android 9).
I wanted to downgrade since EMUI 10 has a bad performance and random ridiculous freezing issues almost in every app with no reasons, now I'm Enjoying my phone once again XD.
Conclusion: If you are on latest firmware update you won't be able to get the switch to an earlier version button on PC Hisuite, Insteadly you will need to downgrade to any previous EMUI 10 versions before you can downgrade to EMUI 9.
Happy downgrading to you all.
You can downgrade through Hisuite don't need any dongle.Just install Huawei hi suite in pc and you can do it from there 100% official

Hi m8,
You can't downgrade to EMUI 9.1 using dload firmware, you will get yourself a softbricked device. The only way is to use HiSuite PC version. If you can't find the Switch to other version, may i ask you how did you get EMUI 10 on your device? Did you used the firmware from other cust and also used a bypass method, like renaming all zips to update? Or other method?
Later edit: are you sure your cust is C815 and not C185?

Glad you sorted out. That's what i was going to reccomend you when you would confirm me that your cust is C185 or C815 ?. HiSuite is offering the downgrade option but not always from latest, therefore the need to downgrade to a previous version.
Don't forget to disable AUTO updates from Developer Options, otherwise you will be prompted to update to EMUI 10 and guess that it will auto download the firmware and maybe it will install it by itself

I've replied you on my dload firmware thread. Use dload firmware from my OP, downgrade to v190, then connect your device to HiSuite and check for an update. There it will be the option to return to EMUI 9.1.0.260. Be aware that using dload and HiSuite to downgrade will wipe clean your phone's data ?

You need an OTG cable,usb formatted pen drive.
