Downgrade to OS11 failing - OnePlus 8T Questions & Answers

Hello! first thanks for reading
I'm having problem downgrading my Oneplus 8T, model KB2005.
Some weeks ago I upgraded my system and I've been trying to downgrade since then, because I like os 11 more.
I've following this guide (downloaded the EU version and the APK) installed it on my phone, and selected the file as it says, but I get this message and I can't do anything more.
Do you have any idea about whats happening? or even if someone out there has been able to downgrade at all hahha.

So you're on KB2005 C.15 (NA) and trying to downgrade using the BA downgrade zip?
Why don't you try the NA downgrade?

Thank you for your reply, you're totally right, the thing is I didn't knew that my model is NA and since i live in europe, I was asuming that I needed the EU zip...
The fun part is I've been in chat with oneplus support this evening, and I told them everythingn about the phone, model, imei, version, android, etc, but they didn't told me that I should use the NA zip....
Anyway, I've managed to downgrade the phone, but I have one more question, Now the system ask me if I want to upgrade, but I don't know if this is a os11 update or the "change to os12" update, any idea about this?

C.11 is OOS 12. And KB2005 is the NA version (there's also an IN version).

I see, so If i update now, it will change to OOS 12 again. right?
My OOS version now its 11.0.11.11.KB05AA is it the last ( i mean the last oos11) version? or do I need to update it manually? How should I do that?
Thanks again!

Should my UK phone be updating to Nougat?

I received my UK/Europe phone today and I was wondering if the Nougat update should be coming through? It did a big 450mb update after powering on for the first time but i'm still on EMUI 4.1.3.
Thanks
I've been trying the manual update check for a few hours now, tried rebooting to see if that might help but so far nothing.

If it's anything to go by, I have Nougat and EMUI 5.0 on my Huawei P8 Lite 2017 (same SoC as the Honor 6X) and it is brilliant
Sorry for being such a noob but I how do i identify which update I should select in Firmware Finder?

It looked to be some sort of security update?
Couple of quick questions..
Did you update it in the end?
Which network are you on? If 3 have you had any probs with 4g calls (VoLTE)?
Dude.
Wait for some days. Also here in Austria we got the Update 2 Weeks ago.
I think is a time delay. How long do you have your phone now?
I do not suggest that Firmware Finder tool. Looks not serious in my point of view.
And that confusion about the lots of updates and files in there? No way...
If you do want do update manually, then do it in a right way and flash it by you own.
Good luck.
Just wondering if you ever got your update. I got the Honor 6x this week and still no update. Am on Android 6 and EMUI 4.1.3. Have spoken to Huawei and Three and have got nowhere. I'm no geek so too scared to use Firmware Finder. Is this my only option??
I'm currently on BLN-L21C432B151
But everyone link posted for nougat or through firmware finder I get
Nrd90 test key and on every reboot I get device verification error no matter which version I install why is this
Three sold me an Honor 6x recently which will not update to EMUI 5 or to Android 7. According to Honor UK Tech support, BLN-L21C432B151 will not update and they have no update in the pipeline. Tough luck seems to be their attitude. Three did not have a clue and will not change the phone. Stupidly (as it turns out) I bought from the Three shop in Canterbury, their take is, "too bad" and if I had bought over the phone from Three direct (or on the web site) I could have simply returned it for a refund. Supported my local shop and realise now that I was a mug, I have no right of return even if you feel you've been "stiffed." No wonder the High Street is dying. Anyway, it looks like we suckers are stuck with what I consider old tat which is outdated from day 1. Thanks, Three and Honor. Now I know who to avoid.
I bought 6x from amazon.uk. Updated to nougat with FF. Had problem with disappeared update app in settings after flashing rom from FF but I found 100-150 MB update somewhere here on xda that fixed it. Since then I am getting all security patches every few months. Did not rooted and not tried any custom ROMs yet. I am getting old I suppose ?

China have EMUI 10 few month ago.
i tried various vpn (both on phone and PC with hisuite) from Canada and Asia, but that did not do the trick
still on 9.1 in France for the moment
Seems like CUST and PRELOAD files for clt-l29c636 are up on firmware finder.
Since I'm rooted and banned for OTA update I'm going to update manually with HisuiteProxy method.
This will probably relock my bootloader for good, but that's the way it goes, I'm going to sell the phone anyway.
Method seems working, update showed up in Hisuite and I'm downloading now.
It worked! updated to 10.0.161 with no data loss
bootloader was relocked
cheers
Does it pass safetynet?
And which of the 2 variants did you install?
Yes, it passes safety net.
I used this files, see this post

Does anybody get who is from Europe?
Sent from my CLT-L29 using Tapatalk
I also installed emui 10
I used the French tutorial with hisuite proxy
Europe firmware but with cust and preload from china c00e1536
Can i install just cust and preload c636 instead the chinese one without the whole firmware
I have problem with play protect verification in google play
All apps works very well inclusive banking apps like bt pay in romania
I'm from Romania
Ah, its that time again
Should i do this Update with the modded Hisuite (i think i forgot it already) or wait some months?

Updated to Android 10 through normal OTA in Spain. Data preserved, without any problem. Everything works fine. (model XT2019-1, RETEU)
Hi,
I have an issue related the adaptive brightness: it's activated but the brightness not changing (at the moment it remains at 82%). If I modify manually it remains at that value.
I have already:
- disabled/enabled it
- rebooted the smartphone
- reset the smartphone
but the issue persists.
Any idea?
Thanks.

Downgrading P40 Pro (11.x.x.x - 10.1.0.168 - 10.1.0.131 )

Hi.
I like many others have been attempting to install Google Services through bender_007's Googlefier on my P40 Pro. I've managed to downgrade to 10.1.0.168 but still need to downgrade further to 10.1.0.131. The phone is bought in Mainland China where I'm living and therefore the firmware may be different to the majority on this forum. I'm just wondering which firmware to flash back to 10.1.0.131 without bricking the device.
For example bender_007 has listed 4 download links for P40 Pro and I don't think any are compatible with my device? :
P40 PRO

Just a little bit lost with all the firmware types, and haven't seen my version of the phone mentioned in the forums. Any help would be greatly appreciated, thanks.
No they won't work with yours, the first 4 digits (C432 / C636 etc.) are for regions so you need to find the firmware built for your correct region.
Try taobao see if you can find any solution
as far as i know ,if your phone from china variant , you can use lzplay in emui 11 . just search for youtube ,theres a tutorial for it ,but in chinese .
My USB stopped working after I downgraded. Now I can't connect to a computer at all.
It updated via ota to .182
My original build was C636E3R5P4.
Any ideas?

It's now stuck at the 12.6 OTA as this is the one that checks for the region, I will follow your guide and let you know how it went thank you for everything
It's giving me the error ''the current system is not compatible with this hardware'' then powers off.
I honestly did not expect that there would be one more update and much less expected it to be a new version of Android, I thought I would stay forever with Android 11
I just hope they fixed the issue of notifications not showing up.
Now to wait if they dare to release a new Android update for the Global version.
