[Newbie Question]TWRP gone after OTA update OSS 5.1.6

I have an oneplus 6 with official OSS 5.1.5 and TWRP installed. But after OTA update my phone to OSS 5.1.6, i cannot boot to TWRP anymore. Is TWRP gone after OTA update? My OEM unlocking still unlocked.

Have u not read anything in these forums, tutorials or anything?
There are like 50 threads on how to upgrade and about the new partitions for op6, it is even clear when u installed twrp too

Hi, just to clarify when you install an OTA on the oneplus 6 it uses the new partitioning system which is different so to remedy the situation just try reflashing TWRP enchilada installer using fastboot.

Previously, i've installed Beta(unofficial) version of TWRP, now i want to re-install TWRP with Official version , do i need to remove or do something firstly?

To fix it just download the official TWRP for oneplus 6 from the official team win recovery project page and then you put that on your phone, and flash using your currently installed TWRP then after that make sure you also install the root package as installing the new version of TWRP will modify the new boot image, Also a good time to mention that it will install in both slots (Seamless update slots) Treble slots if you will just to be aware.

Just follow one of the many upgrade guides. Skip the part about upgrading to 5.1.6 but for the rest follow the steps exactly. No need to explain all this in yet another thread imo. You'll need a pc though.

that's would be great if twrp can be flashed and stays there without wiping as well as root.

Pleasssseeeeee read before creating a new thread

Wait!
Don't install 5.1.6 ROM because OP has retired it. The last version availabe on OP site is the 5.1.5.

You can't boot into twrp because it's not there anymore. The OTA created a completely stock version of the OS that you're now booted on. You need to reinstall twrp and magisk according to the posted guides. This is going to be the case with all OTAs. The stock updater looks for root, and when it's there, it installs a complete OS, not an incremental update.

At first: backup data and phone memory.
You can do local update (download from official web site oneplus https://oxygenos.oneplus.net/OnePlus6Oxygen_22_OTA_045_all_2004142201_bdd6fdc6b6b1477f.zip, v.10.3.3 or from nonofficial sites 10.3.4, copy to phone memory, main directory, go to settings and system update, make local update - and choose copied file from phone), next after update and restart, do wipe cache, restart and you will see what happend.
Try to read oneplus guide:
How to upgrade system?
Download the software build for your device on this page. Please back up your data before flashing your device.
Plug your phone into your computer and copy the downloaded .zip to your phone’s storage. If you’re using a Mac, you can install Android File Transfer Android File Transfer for this operation.
After the .zip file is copied to your phone, go to 'Settings' - 'system update', click the 'settings' icon on the top right corner, choose 'Local upgrade', find the .zip file and click on 'Install' to confirm.
The update takes about a minute (depending upon the file size), once done reboot your device to boot into the latest Oxygen OS.

oneplus 7 Pro , trying to update to Android 10

I had a oneplus 6 and that updated to android 10 a while ago.
Now I recieved a oneplus 7 pro. But the problem is it will not update to android 10.
Tried a system update check, Said up to date.
Contacted oneplus they mentioned the local file upgrade
Downloaded that ZIP and tried again, it tells me system update installation failed.
I am rooted and have TWRP installed as well as magisk.
Considered flashing from TWRP, but since it is an official system update not sure how that would work.
Is this my best option or anyone have an idea on why it fails.?
Tried different suggestions, nothing seemed to work. Did not try to delete cache yet.

Hi
Did u try Tool All-in-one? Marvellous tool!

Updater didnt work, but ended up booting from local updater after the file was downloaded.
Then I ended up doing local update with the update from oneplus latest.
Now I am working on redoing TWRP. It is sticking on fastboot mode after doing a fastboot boot twrp-3.3.1-4-guacamole.img
Just hope I didnt mess something up when I did the TWRP Magisk A/B retention script.
May try a different TWRP boot img

Newest TWRP worked fine.
ReInstalled Magisk.
All Data and apps are good.
Few minor issues but nothing to serious.
Thanks for all your help !!

[Pixel 3a][Android 11][ROOTED][TWRP 3.6.0] Install OTA without reverting to stock

Hello!
I am on an older version of Android 11 and I would like to install the latest Android 11 OTA without losing root and TWRP.
I know that I could just manually flash the lasted Android 11 firmware, then re-install TWRP and Magisk, but this would mean losing all data and having to reinstall apps, restore backups, etc...
So I was wondering if there were a quicker way to install OTA updates without losing data and root.
I know that there are many articles on the subject but they all refer to a previous version of TWRP and Magisk. Because TWRP 3.6.0 sports a completely revamped codebase I would like to know what is the latest recommended method if any.
This is my system info:
Android 11 sargo-rq1a.201105.002-factory-2433e0c0
Magisk v23
TWRP 3.6.0-11_0
Japan region
PS I do not intend to update to Android 12 yet

I ended up flashing the latest version of the stock firmware and reinstalling TWRP and root. However if you have a solution please post it for future reference.

I was looking for the same thing, didn't find any good solution, however, you can edit the flash-all script so that it doesn't wipe your data (remove the -w argument if I remember well).

The flashall script will still remove TWRP and root though, right?

Yeah it does, you have to reflash them after

It's annoying that we can't choose the OTA android installs, it has to be the latest one. On some phones you can choose a local file, but I didn't find a way to do so with a pixel 3a.
If you were able to do this, in theory you could just flash the magisk module for twrp retention and preflash magisk on the unactive partition after installing the ota but before rebooting. Then just reboot and you keep everything.
I'm not ready to update to android 12 either (gravitybox, twrp), but I'll try then...

I don't understand. Just flash the Full Factory OTA zip in TWRP. That won't remove any data. And you can just check the box to "Automatically flash TWRP after zip" so that you'll keep whatever TWRP you're using. Then you just have to reboot recovery (so that you're on the updated slot) and flash the Magisk APK in TWRP. Reboot and profit.
P.S. This post belongs in Q&A.

I wondered if you could do this, apparently TWRP doesn't recommend it.
Also I had no idea how this works on a device with A/B partitions. Does TWRP automatically flash on the inactive partition?

That 'recommendation' is specific to incremental OTAs. Also, it not generally being supported isn't the same as it not being recommended.
TWRP will install the zip to the inactive slot, and then when you reboot, the device will automatically boot into the updated slot.

Thanks for the precisions, I'll know for the next time. TWRP really is awesome

hi everyone, i flashed pixel 3a to android 12 and now my imei is 004400.... and no service ..... what should i do?

How To Guide How to Update OOS 12 with Root

Hi Everyone, there seems to be a lot of bits and pieces in regards to updating OOS 12 and Root so I thought I put together this guide on the way I do it while retaining Root. Unless something changes, this method should work for all future OOS 12 OTA updates.
Please read through all of the steps below before attempting. I will take no responsibility if something goes wrong, this works for me on my OnePlus 9 LE2115 and it should work for other OnePlus 9/Pro models.
1. Install Oxygen Updater app from the Play Store
2. Download the Full OTA.
3. Download and install the OP Local Update app ( apk).
4. Use the OP Local Update app to flash the Full OTA (you will lose root and custom recovery).
Optional - Retaining Root
DO NOT REBOOT if you want to keep Root
5. Open Magisk and in the Magisk section, tap 'Install'.
6. Select ' Install to Inactive Slot (After OTA)'.
7. Tap ' LET'S GO', let it run and then reboot.
After the system boots back up, check to make sure you have retained Root. You will not lose any data doing it this way.

What do you do if you've rebooted, are on the new OS but don't have root? When I go back to Magisk it's asking for an IMG file... I saved the last used kernel before upgrading (11.2.10.10)

I tried installing that app, which looks like its an udpate for a system app (system updater) which is prob why it fails.
I was previously under the impression that this app was to replace the missing system updater in OOS12.

This guide is for updating OOS 12, i have not tested it from OOS 11 to 12. It looks like you just need to flash the patched boot.img again.
Also, just to make sure, you didn't reboot the phone after flashing the Full OTA? After flashing Full OTA, you need to go straight into Magisk as per instruction.

Yeah, it does not replace any app, it installs a new one. The Local Updater app is only for OOS 12. In OOS 11, it's integrated into system Updater but for some reason in OOS 12, OP removed it and created a seperate app for Local OTA flashing.

I rebooted per old instructions and that is what messed it up.
Used the Oxygen Updater to re-download the OTA.
Extracted the boot.img with payload dumper.
Patched boot.img
Reflashed
And we are good to go.

Ah, right. From the other thread. Good to hear it's all sorted out.

If you are looking for the boot.img for a OP9 (not pro) LE2115_11_C.47... here you go:
Meet Google Drive – One place for all your files
Google Drive is a free way to keep your files backed up and easy to reach from any phone, tablet, or computer. Start with 15GB of Google storage – free.
drive.google.com
This is valuable if you get stuck in a position like I did on C.47 without root. Patch this file with Magisk and follow the instructions as you normally would when flashing for root:

So, how did you get from e.13 to c.47 with root?
1. Download c.47
2. Install it via updater - no resart
3. install the patched_boot.img in inactiv slot
4. restart
Correct?

I uninstalled Magisk (restored images).
Rebooted (I shouldn't have done this)
Updated via OTA; rebooted.
Confirmed I was on the new version; indeed I was... completely new UI... did not lose any data or apps
Used the update app to redownload the OTA, copied it to my computer, used payload dumper to get the boot.img. Moved that back to my phone, patched with magisk and reflashed and voila.
I'm not sure on the exacts in terms of versions that I was on before but I did back up the kernel prior to all this (force of habit) and it was 11.2.10.10.

Thank you, i will try
1. I will just restore the normal boot.img
2. Update via OnePlus Update app from device
3. reboot
4. install the patched_boot.img in the inactiv slot
5. restart
Done!

So to be clear, we can now upgrade like we used to, by downloading full image From Oxygen Updater, using system update complete the upgrade, then go to magisk and install to inactive slot and reboot?
I tried this with the earlier 12 release and it went poor.
Luckily, I realized before trying this, is this only for 12 to 12 udpates and not 11 to 12? If the former, it may be best to clarify.

I am not sure. But like I understood you have to unroot before...
@Nick James am I right?

Honestly this OS sucks. I wouldn't waste your time. I'm going to factory reset tomorrow. It's that bad.

The steps I provided is only OOS 12 to OOS 12. I have not tried these steps from OOS 11 to OOS 12. My assumptions is it should still work since you are flashing the Full OTA, it pretty much overrides everything including boot.img. This is why you shouldn't reboot after flashing the OTA if you want to keep root.
However, this is just an assumption, if someone who is currently on OOS 11 can test it out and report here, that would be great.

You are right for OS12 but not OS11. Therefore I assume you have to do my mentioned steps, but like @Z-Blade wrote, anyone has tested here yet...

Hello I tried it today. Like this:
1. I will just restore the normal boot.img
2. Update via OnePlus Update app from device
3. install the patched_boot.img in the inactiv slot
4. restart
Everything seems normal, but I am ony able to connect to the internet when in wlan...

I went from OOS 11 to 12... I wouldn't say the upgrade went smooth thus why I have to reinstall the OS to see if that clear things up. This OS is still really buggy from what I can see but it could be due to not clean flashing. Just beware is all I'm sayin'

So, my internet is back to live...after some reboots it works well
