Hey everyone. As the title says, can i revert back to stable version of OS Nougat by flashing the OxygenOS 4.5.1 ROM? (Its 1.46 GB) I'm unrooted and on the stock recovery and bootloader is locked. Can I simply do a local upgrade? If not, whats the procedure?
I'm asking because the guides i found on this topic mentions a special build of OS which is the Open Beta version, but i don't want that. I want to revert to the stable version of OS on my OP 3T.
You cannot revert back to Nougat/Marshmallow directly from the Open Beta. There is a special firmware package to be flashed and there is partial loss of data.
As quoted on https://forum.xda-developers.com/oneplus-3t/how-to/coming-update-oos-based-7-1-t3564240
"Notice:
If you want to revert back to the last Open Beta N build (OnePlus 3 Open beta 24 or OnePlus 3T Open Beta 15) you will need to flash the special build provided below. Because of the nature of downgrading from a major version, this will cause you to lose partial data.
Instructions and Info:
The build will wipe app and cache data, but Internal Storage will be saved (ie: pictures and files)
Users who revert their device back to the special build can still OTA update the device to Android O build at a later date."
You can't install the stable version directly, only via the installation of the special build, then installation of the stable package.
Are you sure that if u have TWRP then u can't flash directly the stable OOS rom?

I'm not sure about being on TWRP and flashing an older build, but since OP is on Stock, he'll have to follow the instructions as given by OnePlus.
Hello everybody,
I was just wondering if there's any daily driver Treble roms out there that you would suggest, Thanks ?
I'm using phhtreble AOSP 9.0 v111 (with gapps) on top of Xiaomi.eu 9.1.24 and it's working flawlessly. Only thing I can't test is the screen cast thing, since I don't have an enabled tv and VoLTE since my carrier doesn't use it. Also GCam crashes when trying to use slow mo. One last thing, I'd recommend using Magisk Canary 18.2 since that works. Cheers.
liquid or descendant, im using liquid tho

How did you flash MIUI 9.1.24. What I mean did you remove Firmware Update folder from the ZIP or leave it be? I am currently on MIUI 8.7.5 and affraid to get Anti Rollback protection. So I remove this Firmware Update just in case, but after flashing such ZIP my MI8SE doesn't want to boot. It stucks on MI Unlocked logo, it is not even a bootloop.

I think Xiaomi.eu roms shouldn't trigger anti rollback anyway. If you want to be safe flash a China Pie rom, then Xiaomi.eu 9.1.24 then whatever. I think I did china 9.1.3, eu 9.1.24 and PE 190111, but I'm not sure
@guglicap
Thanks for all the tips. Before I had MIUI EU 8.7.5 as a base. I could run most treble GSI, but with some problems and issues (like phone reboot after trying to make call or a few reboots before the system finally started). With MIUI EU 9.1.24 as a base they seems to run much better. I will try to test more features soon.
A few remarks from myself for anyone who wants to try treble GSI:
1. Flash full MIUI EU zip, do not remove Firmware Update folder as I tried before. Firmware Update contains some necessary files to be flash to run latest builds. Regarding the Anti Rollback protection... I had a FALSE response for fastboot getvar anti on MIUI EU 8.7.5, and after MIUI EU 9.1.24 I have anti:1... so it is still safe.
2. Use MIUI 9.1.24 (xiaomi.eu_multi_MI8SE_9.1.24_v10-9) as a base, not the newer builds, as they did not work for me. Also use TWRP 1227 for this build.
3. You can also use MIUI stable 10.2.2 (xiaomi.eu_multi_MI8SE_V10.2.2.0.PEBCNXM_v10-9), but this build works with TWRP 1217.
4. The precedure to run GSI is as below:
a) preferably clean: System, Data, Cache, Dalvik-Cache
b) flash MIUI EU as above, make sure it boots
c) flash treble GSI as System Image (there is many available, I prefer Resurrection Remix, LiquidRemix, HavocOS, AEX, AOISP... I find them the most customizable)
d) clean Cache, Dalvik-Cache, Data (or format Data as an option)
e) disable dm-verity in TWRP => Advanced => RM-dm-verity (very important, as most of the GSI will not run without this step)
What I still need to figure out is:
- encryption (that is a must have for me, so far with no luck on MIUI nor on treble GSI ROMs using the system build in option)
- camera (either working MIUI Camera or GCam, as the AOSP cameras are really bad)

About camera, this works well for me https://f.celsoazevedo.com/file/gcamera/MGC_6.1.021_MI8_V2b_plus3.apk
you need to flash a Magisk module for the fix which is in another thread. Even slow mo works.
Also, I never had a problem with dm-verity, could you elaborate on that? I'm curious now.

phhtreble AOSP 9.0 v111 ROM worked out-of-the-box, with dm-verity untouched. But for many other ROMs I got bootloop. You need to disable dm-verity to make those ROMs to boot properly.
phhtreble v111 with magisk on top of miui pro seems to work without any problem.
The only bug i experience is that google camera crashes when entering slow-mo mode. Also, notification light works only for charging battery.
Geekbench 4 shows the same results as on miui, battery life seems pretty solid.
Currently using it as daily driver, no problems so far.

Hi, apparently it doesn't.
So, after i've spent few days with phhtreble v111, i've noticed the following bugs:
-Bluetooth call doesn't work (the phone rings, music stops playing, but the call runs through the phone speaker)
-Double tap to wake doesn't work
-LED lights up only when charging (Lightflow and other apps designed to take control over it are unable to do it)
-Front facing flash is dead
-Slow motion crashes camera app.
In rest, everything else seem to work fine, even the notch cutout.
Battery and performance are rock solid, substratum is fully compatible.
For camera, i use BSG's Google Camera, which excepting front flash and slow-motion, works like a charm.
Since those bugs are not critical or annoying, at least for me, i currently recommend it as a daily driver.
I have now OB 30.
How I install the Pie official? I must to be wipe all?
Probably, but not sure. I don't know if that particular case (OB > Stable PIE) has been tried/tested or not. You can check the thread (last few pages), but I've been reading it, and haven't seen any reports of that particular case.
https://forum.xda-developers.com/oneplus-3t/how-to/official-oxygenos-5-0-1-android-8-0-t3728119
Folks have gone from PIE Community Beta to Stable Pie, without wiping. Or from Stable Oreo to Stable Pie. And then, some folks had to format data to get PIE to boot (so reports vary).
OB to Stable, I'd do full wipe, or at least be prepared for that contingency (backup important data off-phone, etc.). Really, you should always be prepared for that when installing a major update or new ROM.
How to install this on OB 30?
Stock recovery... not be able by sideload and from recovery/system update..

You are talking about IR unlock. and it sounds like you are already using it. For example, go into a pitch-black room and use face ID to unlock the phone. if it unlocks in a pitch-black room, it's already activated. You will notice the IR receiver turns red as this happens.
While the Stable rom is great, once you can unlock the bootloader, give the custom Miui Xiaomi.EU rom a try. The Xiaomi.EU rom includes all of the bleeding edge features that have not yet made their way onto the stable rom. Plus, there is no need to disable ads, there aren't any to disable and you do not need to change regions, to be allowed to access the best features.
Additionally, Xiaomi.EU rom is based on the Weekly developers, China builds, and as the stable build, Google Play services is built-in, it also includes the drivers from the global build. The only drawback is that it is released weekly, and if you flash updates with every release, you will experience occasional bugs. ( it is based on beta afterall) So, it's best, to stick with the builds without bugs and update only occasionally instead of weekly. With that being said there are also many great custom ROMs, including the latest Pixel Rom which is also stellar.
Enjoy your new phone.

You need to format your data partition. All your files will be lost, so try to backup them somehow. You can find how to format data using TWRP on YouTube. Good search.

You may need to mount system first, and then your desktop may be able to see the files. You will also need to install root, until you change from stock. I would suggest using Orange fox, but it's different from using TWRP.
Since you have TWRP, keep using it until you have mastered it's use than change to Orange fox later.
The stock Rom automatically encrypts your data so as the other person said you may need to format user data. Format type yes, reboot to recovery
When wiping on choose wiping caches, data, and storage only when needed. i would suggest buy a fast USB 3.0 drive and a OTBA to USB A adapter. You can get them cheap at places like Walmart, typically around $5.
While videos can be helpful, this page can answer any of your questions about TWRP : https://twrp.me/FAQ/
just take your time, never wipe Persist if it's in the wipe menu, never wipe system unless using a rom that instructs that you do so. in most cases swiping factory reset is all you need to do when installing new rom.

Can you see my signature?
Rollback protections were never enabled on the Mi8 by Xiaomi, so why wouldn't you be able to downgrade? You will have to format data though. (format, not wipe)
Next the newer versions of Miui 11, especially the beta versions are vastly better than previous builds. There is a a lot more features, more overall fluidity, less issues with permissions and notifications, and better overall battery life.

Please read all indications before proceeding.
Proceed always at your own risk!!!
I did the test to perform the transition from OpenBeta firmware to stable release, using the keep_data file without deleting data, and keeping the root already present on the phone.
The steps are simple, first of all you need to:
Download the complete firmware file
Download the keep_data apk file
save them in the phone's memory, after which you proceed with the local update (ignore the data deletion warning) and once the installation is completed you DO NOT NEED TO RESTART THE PHONE (if you restart now all data will be erased).
Now we install the keep_data.apk and run it, confirming that we do not want to delete the data, even now we DO NOT RESTART but we open magisk, select the "install" button next to the magisk version already present and select "install in the inactive slot (after OTA)", proceed with the installation and when completed, we can finally reboot.
We will have our Oneplus with OxygenOS 11 Stable firmware, root and magisk installed and all our data present.
I tested everything on Oneplus 7 going from OpenBeta4 to OxygenOS 11.0.1.1, I still recommend making a backup of all your data before proceeding, safety first of all.
TESTED ONLY WITH OXYGENOS 11 FIRMWARE.
The keep_data application, has been released for use with OxygenOS 11, I have no way of knowing if it is also possible to use it with OxygenOS 10.
I was a tester and everything went smoothly, no problems or abnormal behavior but
it is important to remember that proceed always at your own risk!!!
full wipe is always recommended in the transition from beta to stable and vice versa.
Good luck!
Original reference source for the keep_data.apk file, present on the oneplus forum here.
UPDATE: the guide is valid and working even using the rollback package firmware necessary to switch from OpenBeta 5 to OxygenOS 11.0.1.1
Proceed always at your own risk!!!
If I wanna try this, it means that I have to install the rollback build from here and then install the keep_data.apk, right?

I didn't use the rollback package, I used the standard 11.0.1.1 firmware.
I believe that, with rollback package, wipe is done before firmware installation so keep_data apk would be useless.
However, using the standard firmware file I have not encountered any problems.
UPDATE: keep_data apk work also with rollback package firmware.

Unfortunately this is normal, OpenBeta 5 is newer than stable 11.0.1.1.
In this situation, the options are full wipe with the rollback firmware package, another option is to wait for a new stable firmware release, that will be newer than openbeta 5, another option is to check if the procedure I wrote also works with the firmware rollback but I have no information about it.

Tried this just now and it works flawlessly! Thanks bud!!!! Now to wait until the pixel 6 comes out and switch to that
FYI for those who want, the new stable update V11.0.2.1 can be updated over Beta 5 without having to use the rollback update and using the keep_data apk works to avoid wiping data when flashing.
Hello is that working for Update from 11.0.0.2 to 11.0.2.1 without losing root ?

No, this guide Is only for switch from beta firmware to stable without data wipe.
For update firmware without losing root, follow this step (before to start make a BACKUP, BACKUP, BACKUP,
BACKUP, BACKUP ):
Remove all installed magisk module and reboot phone.
Download full firmware 11.0.2.1 and save in phone storage memory.
Install new firmware but DO NOT REBOOT WHEN INSTALLATION IS COMPLETE.
Open Magisk and select "install" in magisk section.
Select "Install to inactive slot (After OTA update)".
When magisk installation end, reboot your phone.
Restore your magisk module.
Finish...latest firmware release installed and rooted .

Just used this to rollback from Open Beta 5 to stable, thank you!!
Will it work with a prerooted phone?
I mean I am just on beta build (didn't root). Can I install the stable firmware and use the app to retain the data? Or is root a pre-requisite?

Root privileges is not required to perform the firmware change while retaining user data, just ignore the magisk installation step and reboot phone after running the keep_data application

You cannot update with "Local upgrade" feature, if the new firmware is older than the firmware installed on the phone.
If you currently have Openbeta 5 firmware, you can install the stable 11.0.2.1 or the latest 11.0.3.1.
The downgrade is still possible but requires a specific firmware package and the complete data wipe.
