Which firmware to downgrade to for performance/usability

At this point I have given up on Android Q on this device and I'm having problems to decide which firmware version to downgrade to. I don't need latest bells and whistles, I like my phone plain and simple with no lags/freezes and minimal amount of bugs. I was overall happy sitting on latest Pie update, but Im not sure if performance was better on latest Oreo firmware since it has been such a long time.
What are your takes on this? Should I go for latest Pie or Oreo firmware?

If I would go back to 9 (pie) I would try to find the version which still had the dt2w function. There's 2 different display version of mi a2 lite and because of that they figured it's easier just to remove the function and push out 1 update that fits both version rather than working on 2 separate update just for 1 phone model.

I'm pretty sure my phone has a screen without dt2w function anyway. If dt2w function is on by default, then it should work here on android Q as well unless they disabled it universally? Because here I am, tapping on the screen and its not waking up and never has before either
Thanks for your quick answer. So I should be looking at flashing V10.0.20.0, it seems to be the last Pie firmware looking from here.

Yee. That's the last pie update.

Technical rom question

Is it technically possible to make a custom android 10 or android 11 rom for this phone?

Technically possible? Maybe? Will it be able to even run it decently? Probably not. This device is nearly 7-8 years old, it wouldn't be worth the hassle for the performance you'd get

If you are looking for something newer check out the LG V20 or V30 as they should be able to run a custom Android 10 or 11 Rom.

General OOS12 is the worst OOS ever

Basically, it just changed the user interface of Coloros 12 to OOS12, which is a completely different system compared to the previous OOS, and within half an hour after I updated to OOS12, I was back to OOS11. It's a complete waste of time

i agree oos12 is ****ing dogwater lmao

Is it possible to install ColorOS 12 over OOS12?

Why did Oneplus ruin my new oneplus 9 pro with this crap. Now I am back to rooting and Rom'ing, in order to be on android 12 that isn't a complete disaster?
(rhetorical question).
I thought 11 was a downgrade from 10, as well. But nothing like this. And I could get 10 for 9 pro, since it released with 11

what did you decide on? i feel like 12 is bad all around unless there is a pixel experience one or a A11 themed 12

Look for it here on the forum.

Any way to downgrade 12 to 11 ? Or i need to root and go for custom firmware?

Look here: https://forums.oneplus.com/threads/closed-downgrade-to-android-11.1533089/

Oxygen OS 12, or should I say Color OS? is a disaster. I went back to 11 after like 1 hour.

Use MSM tool to flash. The best way to go back clean.

I did last weekend but immediately went back to oos11 due to no working data.

I will wait untill we have a trick to record call like OOS11.

custom rom time

For what it's worth, OOS 11 did not give me the performance on the 5G Network that OOS 12 is giving me now.
OOS 11 I simply edited the policy restrictions in order to access the 5G cell towers and the download speeds were 50% slower than a comparable 5G capable handset (iPhone 13 pro max, Motorola Razr 5G, One+ 8T 5G). Even after unlocking the bootloader, rooting and reapplying the modified policy restriction.xml the One+ 9 Pro on the OOS 11 had poor 5G download speed.
OOS 12 with unlocked bootloader, rooted, and using 5G switch (playstore app) the 5G download speeds improved greatly. I would say they are 50% faster than same handset on OOS 11. I cannot access engineering mode and therefore modify the policy restriction.xml file like on OOS 11, but given the faster download speeds I'll take it for now. For what it's worth, 5G switch would not work on OOS 11.
Another great option that OOS 12 has is a separate volume level for Ringtone and Text Tone. I NEED to be able to hear my text tone alert (which is usually a very short burst) all the while keeping the volume of the ring tone down so that I can take my time to analyze who is calling without disturbing those around me. OOS 11 combines ring tone and text tone under one forced volume setting, which blows imho.
I personally don't find the interfaces of the two much different, and cannot say that I have noticed any real speed differences or battery consumption pros and cons. I do like the graphical design of OOS 11 over OOS 12, but that can be improved by using different Launchers if that is your thing.
Cheers

Buyer beware - the latest OTA for OOS 12 comes with (apparently) an encrypted-ish bootloader that refuses to boot patched/rooted kernels or recoveries. I learned this the hard way on my 8t. So if you want keep root, it's MSM and custom ROM time.

Nothing new and nothing to be worried about. You need to disable boot verification by flashing a blank Vbmeta.img, and after that everything works like it's out of the box.

If it's running fast and stable and fulfilling its purpose I would leave it be.
Updates can and do break things.
Pie is a good OS. This Samsung N10+ I'm using is still running on it, deliberately.

You can always upgrade at any time. Be aware of 9's vulnerabilities and take appropriate steps to mitigate the risk. I run Karma Firewall and recommend it, freeware that uses almost no battery. Disable wifi and bluetooth if not used or when not in use.
In general security is not an issue with Pie, it holds up very well.

Question Normal to be stuck on Nov 2021?

Morning all, I went through the pages but couldn't find anything that relates to this. Bought the 9pro yesterday (US version, unlocked, using a TMobile sim)
Phone can not find an update, it's still sitting on November 2021 patch with Android11. Is this normal? I know the US hasn't been getting much love lately from OP. I'm also aware of updating via sideload but if this lack of update is known to others as well, I'd rather wait it out until OTA arrives. Anyone have advice?

Same for Europe. BUT - be happy with being "stuck" on Android 11. OOS12 is still way too buggy, more of a beta version.

If you want to try out Android 12, you can proceed through the Oxygen Updater app. The last official OOS12 update I was on has been the C44 EU (C46 is out, but not for EU yet), and I decided to give a try to custom ROMs (Jaguar, on Android 11, and crDroid 8, on Android 12).
I'm currently running crDroid 8 as my daily driver, but OOS12 C44 EU was great too (the first OOS12 updates were quite a mess, though).

Thanks for the tip on Oxygen Updater. I pushed my device to v12 C44. Very easy!

Do you prefer a12 to a11 on the 9pro? I'm hearing horror stories, almost afraid to update it. What's your opinion on it

Horror stories? Over exaggerated for the biggest part and mostly caused by the disappointment that originated after OnePlus and OPPO announced a closer cooperation and unified OS.

I saw this yesterday but figured I should at least give it a little time. Two small issues so far. One, it optimized my alarm clock app so I woke up late this morning. Second, the font and spacing seems a bit bigger on everything and I haven't found how to get it smaller yet. I have font set to small. Wifi, Bluetooth, 4 and 5g all seems to be working fine. No issues with lagging, screen, etc. Let me know if you have anything specific you want me to check.

I paid $530 for my 9pro brand new (us version & unlocked). I'm stuck on Nov 2021, I don't see anything super promising regarding A12 or OOS12, so I guess I'll stay on A11 and treat this phone like a mid-ranger. If I get a OTA, yay.... If not, oh well it was essentially 500 bucks for an 888 and 12gb of Ram

Do you happen to know if I root my 9 pro, whether or not I can still get OTA updates? Or, if maybe i could still use Oxygen Updater to do so? I dont mind the stock OS but id love to get Titanium Backup going and a few other small things.
NEVERMIND - Found on the Oxygen Updater site. Still works after root, just a slightly different process.

You'll have to check personally for that, as I'm unsure about how Titanium backup works. But I know you can still use Magisk and keep your device rooted even through OTA updates (the process is described step by step in the associated post on the OnePlus 9 Pro forum, so you should find it quite easily, but be careful, as you have to do a few things before rebooting to apply the OTA update.).
