Oreo beta 1 sideload fails on build NMJ51B

Just a PSA, if you update to build NMJ51B you will not be able to sideload the Oreo beta 1 update. It will error saying your current build has a newer date and downgrade is not allowed.

Confirmed
I should add that unlocking the bootloader will not help, I had to downgrade to NMI81C first to flash the Oreo beta 1.
Can you factory flash NMJ51B when on the Oreo Beta? I keep running into issues when trying to flash.. wondering if that's why.
After running flashall.bat, it will hang up on the first step (flash nvdef.img target didn't report max-download-size)
Same. Just going to wait for beta 2 next week.
Just return back to a previous version from stock using the system dumps in the other thread. I can confirm this will allow you to install the update.

Yes, you can.
If you feel comfortable with ADB flashing then you can flash the latest Oreo beta 2 over N without problems. Just follow the instructions, download links, and steps directly form Essential website.

How to downgrade 9.0 to 8.1

How to rollback from official 9.0 to 8.1 please help me
Yeah not digging 9.0
http://oxygenos.oneplus.net.s3.amazonaws.com/OnePlus6Oxygen_22_OTA_007_all_1805131952_O_MR1.zip
See if you can flash this from settings. It used to allow you to downgrade from Pie Beta. I'm not sure if it will work for Pie Official. You will most likely lose your data if you successfully flash this. So backup your stuff even before attempting this.
Or you can use the unbrick method to completely reflash your phone to 5.1.5 using MsmDownload Tool.

Download the 5.1.11 fastboot rom. Extract it. Open the folder you extracted and run flash-all-partitions-fastboot.bat
You see some things that look like errors but they aren't!! You have to have patients and just wait!!! When it completed it will say press any key. Then unplug phone and boot. You'll be on latest 8.1
Here's the link.

If you're unlocked, flash it trough TWRP and format your storage.
If you're not, on a Sticky thread somewhere on this forum, you can get a rollback build (it's an Oreo build, the latest if i remember correctly, it's clearly called "rollback")
Edit : it's on this page : https://forum.xda-developers.com/oneplus-6/how-to/oneplus-6-mirrors-official-oxygen-os-t3792244
What issues are you all having with 9? I was on the BETA build when I first got the phone and had several issues.. but after downgrading to the recent stable build.. I haven't really had any issues..

Is the OTA the same for all variants, or is this ta-1050 specific and eg ta-1043 has a different file?

I didn't received official OTA via "check for updates" option yet so:
I just manually downloaded and installed this OTA file on my TA-1043 and it works fine! I performed the update via recovery using ADB sideload. Restarted the phone and having android 10. It is so simple!

It is no problem with stock recovery. How to enter stock recovery, just do these steps:
https://www.youtube.com/watch?v=8Fv39sTUvbk
Then you can "Apply update from ADB" or "Apply update from SD card". I did it via ADB sideload.

If that's a Chinese model, no it won't.
From the Android Sage page with update instructions:
Following is the latest OTA update zip or full stock firmware upgrade package. The following OTA update is only for the international variant. Chinese variants will be updated soon. Chinese variants will be updated soon. So stay tuned.

The May update is 11.0.5.0. I have a patched boot with Magisk 20.4

And from 10.0.2.0 to 11.0.4.0 - did you also update the same way, or did you clean flash from fastboot?

I've been using the same process for every OTA since 10.0.4.0.
Only a few updates caused issues.
10.0.9.0 needed a newer TWRP.
Magisk 20 broke TWRP.
When I did the android 10 upgrade I had an issue with some Magisk modules that I had not upgraded. It would have been fine if I'd upgraded them first. I disabled them to boot and then installed the upgraded modules.
Does anyone have the boot img from version 11.0.10.0?

There is no such version for Mi A2 Lite.
11.0.5.0 is the newest release (Android 10 with May security patches).
Hi @a1291762,
I'd like to know if
. it is possible to downgrade from 11.0.5 to latest Android 9
. it is possible to use a full working Gcam on 11.0.5 and how to install it.
Thank you!
I'm currently on v. 10.0.18 (I stopped the latest update for Pie) and I have a CSOT screen.

It was only the first Android 10 (11.0.2.0) that had issues with screens. The 2 followups (11.0.4.0 and 11.0.5.0) work on all phones.
In theory, it is possible to downgrade back to 10.0.18.0 using a fastboot image.
https://forum.xda-developers.com/mi-a2-lite/how-to/fastboot-xiaomi-mi-a2-fastboot-images-t3824871
To get to 10.0.20.0 you'll need to get the OTA zip and install that. I'm not sure how to do that, but this process seems like it should work: https://forum.xda-developers.com/mi-a2-lite/how-to/how-to-manual-update-v11-0-4-0-users-t4082815
It might be worth checking if people have done the downgrade successfully. For example, the Pie-Oreo downgrade caused modem issues.
There's heaps of threads where people discuss gcams, but I do not know what the state is because I use the stock camera app.

Apparently there was a 10.0.20.0 fastboot, but it's not on the fastboot thread

install TWRP in oneplus 8

I want to root my oneplus 8. install TWRP recovery.
please anyone help me how to install TWRP in oneplus 8
I am using oxygen OS 11
Android version 11
Use fastboot to flash the TWRP image to recovery using the following command:
Code:
fastboot flash recovery [name of image].img
Keep in mind that this command will flash to your primary slot; if you'd like to flash it to both, replace "recovery" with "recovery_a" or "recovery_b", which are the names of the two partitions. Your bootloader also must be unlocked for this operation to work.
The link for the TWRP image can be found on XDA.

Hello!
I build Orangefox for the Oneplus 8t and 9r and I am now doing a unified build which will work
on Oneplus 8, 8t, 8 Pro, and 9r.
A new updated unified beta Version is here
Decryption might not work for Oneplus 8 and 8Pro yet but I will try to fix that in the next days!

Yes will do that as soon as I have added working decryption for Oneplus 8 and 8 Pro.
Actually decryption should already work for all OP8 series unified ROMs like Pixel Blaster and FlamingoOS which are unified for OP8 series and Op9r und using FbeV2 decryption method.
