How to upgrade rooted/unlocked OOS 9 to latest without losing anything?

I am unlocked + rooted with Magisk. I want to stay that way.
Last time I upgraded from OOS 9.0.1 > 9.0.2 via UI, the upgrade wiped everything and I needed to start from scratch (as if I just got a new phone). Is there a way to make the upgrade seamless without losing everything? I want to upgrade to 9.0.3

Post #3 has the instructions you need
Long story short you need to flash the update via TWRP.

2 questions - why can't I do #6 after #3? Can I?
Also, do I need to do #4 since I have it already installed?

You can't do either thing you want to do there because of the added fun of the OnePlus 6 having A/B partitioning. With A/B partitioning there is no recovery partition, and recovery is now a part of boot. You need to flash TWRP again because the update will overwrite TWRP with stock recovery. And you have to wait til after the reboot to recovery to install magisk so it gets the partitioning right.

Like above.
Flashing ROM Will also flash stock recovery so after ROM you need to flash twrp again,if you reboot without it it's lost.
Also why magisk isn't flashed right away is because: when you choose to reboot to twrp after the twrp flash it Will change slot, this way you Will get magisk on the correct slot.
All this can be done from the OS.
Install the ROM upgrade as usual,don't reboot.
Open magisk app
Search for a module a/b twrp (you Will only find one module) and install it.ndont reboot just yet.
Go to main screen of magisk
Press install, install, install to inactive slot (after OTA). After this install you can reboot.
Both works, I find the twrp way to be more convenient

I don't about stable i am on open beta 10 i root every beta without twrp using patch boot image i got update every time around 1.5 GB because i am rooted after update i just lose root everything same before update phone not wipe anything

I upgraded vom 9.0.1 to 9.0.3 by
- Downloading the full 9.0.3
- Copy them to the sdcard root directory
- Update via settings / manual update - DO NOT REBOOT
- Reinstall Magisk into inactive slot with Magisk Manager
- Reboot
Works. But Magisk 18 MagiskHide does not work properly on my OP6, so I had to downgrade to Magisk 17.2.
- Download latest TWRP BluSpark .img, Magisk 18 uninstaller, Magisk 17.2
- Copy uninstaller and Magisk 17.2 to sdcard root
- Reboot into Fastboot
- Boot into TWRP by fastboot boot <name of TWRP BluSpark .img file)
- flash uninstaller
- flash Magisk 17.2
- Clear Dalvik cache
- Reboot and setup Magisk (settings in Magisk manager regarding Hide and root permissions were lost).
- Uninstall duplicate Magisk Manager 6.1.x (not compatible with Magisk 17.2).

I do not have TWRP installed, it is basically not necessary as OOS can be updated with the settings/manual update tool and Magisk can be reinstalled via Magisk manager.
I had to use TWRP solely to downgrade to Magisk 17.2 from Magisk 18 as this cannot be done with Magisk Manager. But for that purpose, it's enough to temporarly make TWRP available via fastboot boot command without permanently installing it.
If you have TWRP and want to keep it, that easy process doesn't work to upgrade the OS.

So magisk installs to the opposite partition you're currently booting from? Only reason I ask is because previously, I missed the second reboot before installing magisk and the phone wouldn't boot (long boot logo and eventual automatic restart to recovery). Ultimately, I just permanently installed twrp and was going to wait till the weekend to try root again in case there were issues. I'm currently booting from slot A. How do I install magisk now in recovery? Should I be in slot A or B in recovery for install? Or can I now just do it from magisk manager? Thanks for the info.

I am not entirely sure if it does or not, but again the A/B partitioning puts things in the boot partition instead of the partitions you are used to. Installing TWRP changes the boot partition, so you need to reload that boot partition before installing magisk will work right.

I guess I'll just try this upcoming weekend to install magisk via the manager inside Android. I'll try to remember to report back. Thanks for the help.

As promised, I'm writing back with my findings. I believe some enabled module in magisk was the issue. What I did was uninstall magisk 18 with the latest uninstaller. Thinking it was V18 itself that was the problem, I then proceeded to install v17.3 on both slots (reboot to recovery in betweene). This worked and booted! It started to occur to me that I had not disabled any of my modules before installation of the rom/magisk. This is a big mistake as a lot of magisk modules are still using old formatting and cause new installations to fail if left enabled. Since an uninstall also disables all modules, I believe using 17.3 was not necessarily the solution but rather either disabling modules before an install, or uninstalling whatever version magisk was installed to begin with (which essentially disables/uninstalls those modules anyway). After installing 17.3 and getting it to boot, I just updated via magisk manager to v18 with no issues to speak of! Now comes the part where I need to remember all the installed modules I had and test them one by one.
For uninstallation of modules in twrp, you can use https://forum.xda-developers.com/apps/magisk/module-tool-magisk-manager-recovery-mode-t3693165 Or https://forum.xda-developers.com/showpost.php?p=72542167&postcount=242&nocache=1
I hope this helps someone!

phone has lost root issue

I used magisk on my phone for roots right but it has lost roots. I tried to go into recovery to reinstall magisk but recovery isnt booting, when it select advanced it gives me fastboot or recovery options but when I select recovery its goes back to the start again. I have tried to reinstall TWRP using this method
https://www.xda-developers.com/official-twrp-oneplus-6-huawei-p20-pro/
but I then get a crash dump window.
Please can I get some advice how to proceed?
Thanks

Make sure you're using 3.2.3, anything prior to that is not for Android Pie. If you updated your OS that is more than likely the reason you lost root. Make sure that you download TWRP.img and fastboot through the image before you try to install TWRP permanently

Aha! I did wonder but I followed the guide to the letter as I thought I might brick the phone if I risked the other imgs. I did sort it by using a different TWP file.

Good deal glad you got everything working.

I'm on stock android 10 and I have accepted an update I was offered yesterday. It seems everytime I update I have an issue rooting and installing TWRP (last month I was bricked), maybe because I use the last TWRP version I have before the update (currently twrp-3.3.1-1-enchilada). What is the correct process for installing TWRP and rooting again with Magisk? Do I need to get a TWRP update each time?

You have to install the latest one (3.3.18).
Reboot fastboot, type fastboot boot 'recoveryname'.img, once time you are in twrp flash the installer from the inside. Reboot to recovery again and flash magisk.
When you need to update you have two ways:
1 download the full ROM zip and place it in your main storage folder (sd card);
Update via local update but don't reboot;
Open magisk and download and install twrp a/b retention script and don't reboot yet;
Go in the magisk main page and install it as installation in the inactive slot (after OTA);
Reboot and enjoy.
2 download the full zip;
Reboot in twrp;
Flash rom + twrp installer;
Reboot to recovery;
Flash magisk;
Reboot and done.

Can't install Magisk after flash beta 25

After I'd upgrade to beta 25, I can't install Magisk. Any ideas how can I get my root back?

I'm also facing the same issues. Whenever I install Magisk,phone boots into recovery and will only boot into system when I flash the Magisk uninstaller.
Same thing happens when I flash the patched boot image via fastboot.
Edit: Did a fresh OB25 install via TWRP followed by Magisk 19.3. System booted up smoothly

I have also faced this issue
1.install twrp
2.flash ob25 again & twrp.zip
3.reboot to twrp again & install magisk then reboot to system May be there are some changes in os because of upcoming Q update

How to fresh start in Android 10?

I am on 9.5.11 at the moment. I am rooted with magisk but don't have twrp at the moment. What are the correct steps to go to full stock android 10 and then root the phone again (either with twrp or not. Doesn't matter)?
I am downloading android 10 full rom as I am writing this post.

You can't flash twrp on Android 10. You have to have twrp while in P and then carry it over to Q.
Or flash a patched magisk boot.img then flash twrp installer in magisk manager.
Easiest is to do a local upgrade and flash twrp rentension zip and then install magisk to other slot and reboot system
After that, you can reboot into twrp and do a factory reset to have a fresh install of Q.

So...
1. Install twrp
2. Flash android 10 full rom .zip
3. While still in twrp install twrp retention zip
4. Flash magisk as it is
5. Boot to system
6. Go back to twrp and then go: wipe-format data-yes
7. Restart and phone should boot up normally
8. Go back to twrp and install magisk to gain root again
Correct?

First, do u currently have twrp?
If you do then:
1. Flash the Android 10 through local upgrade
2. Then in magisk flash twrp rentension module
3. Then in magisk, click install and install it to other slot
4. Reboot system
5. After booting into system, reboot to recovery
6. Do a factory reset in twrp and reboot into system
7. Go through setup.

Oneplus 7 Pro Bootloot

Hello, So i tried to install GPS joystick privacy mode app as a system app first thru titanium backup then ..., i rebooted and now im on boot loop, what do i do?
Any help is appreciated, Thanks

Hold Power + vol up + vol down for several seconds should put you in bootloader. Or alteranately, Power+vol down for several seconds should send you to TWRP if you have it installed. From there, I'm thinking you may need to flash the stock ROM again, since you were messing with the system partition, and the phone is not booting now. Either flash stock ROM in TWRP, or use the fastboot stock ROM.

I didn't have twrp installed and i still dont, i patched the boot image with magisk and all i have is root cause i cant seem to keep TWRP installed after 9.5.3, im currently on 10.3.0

You should be able to fastboot flash stock boot.img from the fastboot ROMs to get the phone running again: https://forum.xda-developers.com/oneplus-7-pro/how-to/rom-stock-fastboot-roms-oneplus-7-pro-t3931424
This will unroot the phone. But you should be able to easily root again by the method you did originally.
What is the problem you are having with installing TWRP? You haven't specifically described how you tried to install. I've had no issues using the TWRP installer zip, after multiple updates.

You need to re flash stock so, boot lastest twrp (fastboot boot twrp.img) and flash lastest stock rom.
And if you need an app as system use magisk module App Systemizer (you also need busybox module and Termux app from playstore) this is the only way (that I known) to convert user apps to system

tried that first part too, cant get into twrp and that makes sense now, i installed busy box but never opened the app to install to system/xbin

here's how ive done my part so far.. ever since i bricked my device last feb 24 , rendering it totally unresponsive.. that not even vol up & power button dont work
1. had to use msm tool just to boot my device. successfully boot my device to 9.5.3
2. device seemed to have a locked bootloader again so i un.lock it again. downloaded a patched 9.5.3 boot.img and flashed it via fastboot
3. successful root confirmed..
4. downloaded twrp 3.3.1-75 unofficial installer.. about 17.5mb. flashed it thru magisk as a module.. then install magisk ( as recommended) then reboot.
5. after a reboot.. and setting it up to my liking,, i reboot to twrp to flash the latest 10.3.1 stable rom..
6. flash twrp installer again.
7. hit reboot then choose Recovery . phone reboot to recovery again
8. flash magisk.zip which i downloaded earlier. then reboot.
done
updated to 10.3.1 with magisk & twrp intact..
btw.. i really dont know how to force my phone to reboot to twrp via PC ADB fastboot command.. easiest way for me to install TWRP is by flashing the TWRP INSTALLER as magisk module

That is because that is NOT the correct way to install TWRP img. You need to fastboot boot TWRP, then once in TWRP flash the TWRP installer zip, as I already mentioned.
This is described in the TWRP dev's thread (and you will see no mention of fastboot flash TWRP).
https://forum.xda-developers.com/on...nt/recovery-unofficial-twrp-recovery-t3931322
Also make sure you use a current version of TWRP (latest is unofficial -76) which you can get from the above link.
