Hi i haven't tried yet because i have to backup everything. Oxygen 13 is much better than 12 but is still a colors os and i don't like the ui. I roll back because i don't like the interface, the new dialer and the missing features. Hope i helped you

The same : I upgraded to O12 but I had to downgrade because I lost some features. Do you have some feedback about O13 on Oneplus 8 Pro ?

Hi as i said Oxygen 13 is much better than Oxygen 12 but of course is a ColorOS so you will lose the same features but is optimized better. During these two weeks i didn't find any bugs, simply i don't like it. The only negative thing is that objectively the battery life is worse than Oxygen 11

Thx. Did you downgrade successful with MSM ? (last question )

You're welcome . No i haven't downgraded it yet because i'm working and have to backup all. I will update this thread after doing it. I will post here the result

Thanks ;-)

I am thinking of doing this too. First this 8 pro was the greatest phone ever. Then I, like an idiot updated to Android 12. It was pure crap. All those permission askin and even the alarm clock. I wish they would have gone to stock android rather that ****.
13 is better than 12 but I still think the main thing is that 11 was much more simple and, well worked . My work phone has that.
Main questions are
can we go straight from 13 to 11?
Is there a guide on that already?
Some good youtube videos on going from 13 to 12 and 12 to 11, but not about 13 to eleven.
Oh, one more question!!!
Can you remove the update notification (update to 12?) from android 11?? Work phone op 8 has that.
Thanks!

Hi, sorry for the delay but the holidays and work made me busy during this time. I rolled back following the guide. It has been almost simple and now i have a real oxygen. probably in the future i have to update or replace my phone but for now i'm good. The wordt part was doing backup because it has been really slow due the type c transfer. Hope to be helpfull!

I did step by step. 13 -> 12 and 12 -> 11. It has been a bit more tricky but worked and this is the most imporant thing. For the notification i saw that if you go con system update, press look for update and instantely close settings. The notification will disappear until you turn off or reboot. You can make this operation whenever you want to let the notification disappear

I did this the hard way also. But yeah, for now. The Android 11 is working smooth!! JUST REMEMBER TO BACKUP EVERYTHING!!!! [and make sure you have 3.0 usb-wire otherwise it is slow as hell (the red one isn't)]
First 13>12 with this video:
and secondly 12>11 with this:
HereI had problems. The local update (downgrade" file failed to verify with the app on the video. So I used "OPLocalUpdate_For_Android12.apk"for the downgrade file
Then lasty I updated to the newest version of android 11 with local update. Files from the very bottom of the site
Steps to Downgrade or Rollback Oneplus 8, 8 pro, 8T & 9R from Stable OxygenOS 12 to OxygenOS 11
Oneplus user are not happy about changes done on OxygenOS 12 for Oneplus 8, 8 pro, 8T & 9R. Now users want to downgrade to Stable.

Open Beta Not Flashing ( Vendor Partition Problem )

I have Oneplus 5, I was initially running Open Beta 14, I installed Mokee ROM for Android P and later again flashed OP5 to OxygenOS 5.1.3 Android 8.1 using Qualcom MSM Tool.
But I am not able to Flash Open Beta(s) now,, I tried Open beta 13 and 15, none worked.
I clean wiped using stock recovery, didnot work.
Wiped using TWRP by BluSparx 3.2.3 - vendor still not mounted( as it doesnot exists) and - still Open Beta not flashed after wipe.
I also switched to Android 7.1.1 and tried installing Open Beta 13 and 15 - still didnot work.
Please help me switch to Open Beta ROM for Oxygen OS Oneplus 5
First flash open beta 12 then you can flash ob 14 or 15.

Have you read the post above yours? It's mandatory to update to a special ob first so vendor partition will be created.
It's not made clear in the installation notes for OB14, 15, 16 etc but yes as @bkma says, you need to flash OB 12 first if you are coming from non-OB.

The problem is that oneplus did not implement clean flashing of every beta/stable. The updates are always seamless ota updates, hence its not possible for normal users to skip updates and continue with ob16 when coming from OB11 for example.
That's a thing people don't understand here. The process provided by oneplus is fool proof, but when you did not follow the official way, it can be hard, as always.
Therefore its not mentioned in later open beta changelogs or installation instructions. It was mentioned when vendor partition came up.

I see where you are coming from, and you're right, if you were on the Open Beta program all along, this is fool proof.
I bought a new OnePlus 5 about a month ago, I think OB14 was the latest beta release about then. I had not been messing around with rooting, 3rd party roms, kernels, twrp, anything like that. I was just looking for OnePlus official way to get on to the latest beta. It took me a bit of searching through old forum posts (posts which were made before the time I was even thinking of getting a OP5) to find out how to do it.
The information on the OnePlus website currently is insufficient for new beta users to install it from stable. (unless if you go digging through the old release notes) It's not a complaint, just pointing out that it is a subtlety of going to the latest OB that people would have to be aware of if they are new to the OP5 (or if they have recently decided to move from stable to beta).

Yup I am already on OmniROM Pie Alpha 5.2, which is Android 9 version
Thanks, I will give it a shot surely
I had 2 mate 10 RNE-L21 phones both having OmniROM Pie Alpha 5.2, so I tried OmniROM Beta 1 on one of
them and got bootloop on Factory Reset (it restarts around 20/25%)

Yes, that's because you (we) need to wait the official update to Android 9 Pie, after that, we can flash these ROMs.
How is OmniROM Pie Alpha 5.2? Works fine? Battery life etc...?

Yes ROM is very good, I am using it now on both phones, satisfied, only problem is stock camera
gets stuck if u switch between vdo/image, and some time even if u do not switch, still it will close after a while
So have to use Open camera or Google camera, for which I am not satisfied with both of them

How do you have installed the ROM?
I followed the guide on OpenKirin site but I'm stuck in the page says my device is unlocked and can't be trusted, I've pressed power key to confirm the boot but nothing, it says: "Your device is booting now" but it doesn't go on.
I've tried with another ROM (OmniROM Pie Alpha 5.2 and OmniROM Pie Alpha 4) but same error...
Why?

Now I'm restoring it with eRecovery because the ROM doesn't start.

if you try recording a voice message, the sound is very glitchy and it has a lot of static in it, it's probably happening cause we don't officially have EMUI 9
tho it will release in july or late october for mate 10 lite

Hi,
I installed it on my rne-l21c432b338, then on b340 and on b341.
he always starts.
I use hurupdater to install the stock firmware. (check that you have the three firmware files of the same version.)
a faith installed, I go to REBOOT, select recovery. do factory rest and wipe cache. it restarts clean.
then connect to the PC.
with adb and fastboot, I install SYSTEM.img omnirom. (of course omnirom alpha 5.2
not the new version it is only for emui 9.)
faith flashed, unplug the cable and pushed it into recovery mode and make factory rest and wipe cache.
he starts for me.

In the past I had already installed a ROM from OpenKirin, but there was some problems with it and then I removed it with eRecovery. It has downloaded stock ROM (about 2,7GB if I remember right) and installed it. So I think I'm already on stock ROM (or am I wrong?)
Today I've tried to install 2 ROMs from OpenKirin and nothing happen, I get stuck on "The device is booting now..."
I've never used HuRUpdater (like I said before, I've always installed the stock ROM using eRecovery).
I don't understand what files I need (I know where to find files, here, but there I don't understand anything ahaha)
Probably is this the problem?
how do i upgrade to emui on my mate 10 pro is it even possible with an unlocked bootloader without relocking? the omnirom one is extremely laggy for me even the notificationpanel is extremely difficult to pull down, trying to install the latest rom thats for emui9 just gives a bootloop

A way to quickly update 9T EEA to MIUI 12 instead of applying step by step MIUI 12?

Hello Guys
I just received MI 9T EEA variant. I want it to update to MIUI 12 but i can't apply MIUI 12 update directly because the system version is old MIUI V11.0.3.0.PFJEUXM and i am not able to apply my downloaded MIUI 12 because it needs an updated software version. Bootloader is locked and i have to wait 7 days to unlock. Is there a way to quick update it to MIUI 12 instead of step by step updates?
Get thru the 5GB of updates just like i did, updated it from MIUI 10 (didn't check the version) to MIUI 12.. but did it step by step

You can try the following:
- Download the latest QFJEUXM (supposing you are on *FJEUXM = eea) 12.0.2 Recovery/zip package to your phone from:
https://xiaomifirmwareupdater.com/miui/davinci/
- Go to Settings, Update and tap seven (or so) times over the big 11 (MIUI version number) in the center
- That would unhide few additional options in the menu (three dots top right), namely the option: Choose update package
- Take that option and navigate to the downloaded zip package for 12.0.2
If it doesn't want to update directly, it would probably tell you (once, by mistake I tried updating from eea to global and it stopped me telling that it's not the right package for my phone), then I used the eea package and it worked fine (but I was not jumping from MIUI 11.03 to 12.0.2)
This method does not require the unlocked Bootloader (root, flashing, anything special)

Actually i am AOSP based custom rom user but as i need to wait 7 days for bootloader unlock, i have to use MIUI and there are some new things in MIUI 12 and that's the only reason to update to MIUI 12. I can't say about battery life right now but the new UI is good.

Ok, I'll be on the lookout for a new post before you go to AOSP to see your final assessment so I can get a more concrete idea on whether it's better to stay on Miui 11 or go up to Miui 12 ... I've read a lot of bad things about the battery or lag throughout the interface. A greeting!

What is "here"? (you can find out everything "here" or read "here")
There is no link
Or did you mean you switched to MIUI11 for stability
from what I have researched since my previous post ...Android 11 is in the form of AOSP ported builds (lot of activity on Telegram) and gsi's.

Oxygen OS 12 to Color OS 12.1

Im a OP 8 Pro user coming from oppo find x2 pro , and im having a lot of issues with the new software , no notification badges appearing at all no matter what settings are applied , non customizable AOD , No Themes , Heavy power saving , all of that are ruining the experience to me , it was more comfortable with Color OS on my Oppo , so is there any way to install it instead of Oxygen OS?
i would suggest going back to oos11.

How to do so? And will it feel old to have 11 instead of 12? As im new to OP8 pro and it was already 12 when i bought it , also will 11 solve all of these issues?

OOS12 looks better but everything else is better in OOS11.
But OOS12 is not as bad as you describe. Maybe your phone is on an beta of OOS12. You might wanna check your software version.
I guess you bought a used phone, because im pretty sure the OP8Pro gets shipped with Android 10.
I would go for a fresh start and rollback to OOS11 using MSM Tool.

You can find all these information easily on google. Im not willing to post links from outside of xda.
And yes you can install color os directly.
