There is no Android 7 beta for P9 Plus, only P9.

When it's ready and Huawei will release it.
Very difficult to say exactly when. Stay tuned [emoji6]
Since P9 Plus is the TOTL phone, I hope it receives the N update first.
Also, Aug. 2016 android security patch since I am still on July 1, 2016 level.

If you have P9 Plus VIE-L29 model, you can debrand your phone to C185, and install it from here:
VIE-L29C185B320
Installation guide can be found here on this thread Page 58.
Important points to consider:
Debrand your phone to C185
Install C185 stock marshmallow firmware
Install TWRP (yes, TWRP!)
Flash the B320 nougat beta package using TWRP
IMO, I don't recommend it. It is unstable (bluetooth doesn't work, settings sometimes hangs), and recovering back to marshmallow is another feat. Also, the most important thing is, the Nougat's cat easter egg doesn't work on this build .
DWOR!

No problem with anything aside from a noticeably faster battery drain even on idle after updating to nougat beta, other than that everything is working fine.

Yes, I just flashed the RAW Android 9 file. I have WW version.
https://forum.xda-developers.com/rog-phone-2/how-to/1910-64-ww-update-t4021947
but this is so dumb... why don't they already have it updated. they knew the release was here.
Beta 9 was already the "full" stable update.
ugh. now i need to go back, unlock and then go to android 10.

you can also use the asus downgrader: https://www.asus.com/Phone/ROG-Phone-II/HelpDesk_BIOS/ and download Version Android 10 downgrade to P (WW) - Or use the one catered towards CN version if you have that.

Is it possible to downgrade to Android 8?

Hi guys,
Using Mate 10 (C185) on firmware 10.0.0.180.
Is there a way to downgrade it all the way back to Android 8, without unlocking bootloader or installing custom recovery?
Thanks for your response in advance.

Thanks, but are you sure that i can go from Android 10 to Android 8 with Hisuite?
Just from 10.0 till 9.0.0.246.
I managed to downgrade from 10.0.0.180 to 9.1.0.320.
But now, hisuite dosen't give option for rollback to older version anymore...
Any idea or guide that i can follow from here to Android 8?
madcapfrog said:
10.0.0.180-ról 9.1.0.320-ra sikerült leminősíteni.
De most már nem ad lehetőséget a régebbi verzió visszaállítására ...

Use an older hisuite version!
But unfortunately I was only able to upgrade to 8.1 as well.
I used last hisuite to downgrade from 10 to 8.0 in 3 times. Works on ALP-L29(C636)!

How to Downgrade to UI 1.0 or Flash Stock Rom

Hello all,
I have Realme X50 5G RMX2051.
Unfortunately I upgraded to UI 2.0 and now I cannot use the Android Auto.
So I want to downgrade, but here is no official file.
Could you please help me with a solution?
How can I return to stock ROM, or change to EU ROM?
Thank you!

Hello, I cannot answer this question. If you tell me where to look I can tell you. Do you know how I can change the ROM to the global one? Or maybe to downgrade manually, because Realme does not have a file for downgrade of this model.
Hi, I got RMX2051 for a while, and still find ways to change the ROM version to EU.
But unfortunetely, Realme locks everything on this phone, I think that's the reason why there's almost no resources here.
By the way, if you just wanna use Android Auto, maybe you'd install it through APK file.

Would you mind to post the screen shot or connect condition here ?
It may help to find out the problem.
Attached is the screen
I found Realme X50 5G (Realme UI 1.0) stock ROM here.
But, it shown in Chinese Simplified...
And here is the tutorial from OPPO ColorOS community. (It's the same Recovery with Realme.)
I'd did a downgrade UI procedure once few months ago, but failed, because the Recovery is going to check the version of Realme UI, whether it was older than installed.
Anyway, if you'd decide to do this, please do a completely backup of your data first.
May this help you, and good luck !
