OP2 cannot upgrade from Oxygen OS 2.2.1/Cannot flash TWRP versions newer than 3.0.2-0

So.... Pokemon Go has a lot to answer for......
I have run into a really strange problem when trying to install an OTA on my *unrooted* Oneplus 2. I have been trying to fix this for days but I have completely run out of ideas.
I originally had a working stock Oxygen 3 (Marshmallow) rom with TWRP recovery on my device (not sure of the version). The device was rooted and apart from not being able to install OTAs, I was fairly happy with the setup. Then along came the Pokemon GO update that banned rooted devices. Ok, "big deal" I thought. I was quite content playing Ingress instead (a far better game by the way that doesn't rely on a "pay to win" structure). I really wasn't too worried but then I found out about "systemless root" and "Magisk". I thought that if I installed this correctly I could still play a bit of Pokemon GO when I wanted to and could toggle a root button in Magisk Manager to install OTAs when they became available.
This is where the problems started.
I followed a guide on how to unroot and install Magisk and "Phh's Superuser". The problem was that the Phh Superuser was being denied permissions for Magisk Manager, there were no pop up notifications prompting me to give it access, just toast notifications. I couldn't for the life of me figure out how to give it permission so the "enable root" slider button kept sliding back, not allowing root. This is when I used SuperSU ver 2.76 (Magisk version) and it seemed to work fine. I now had a stock Marshmallow rom with TWRP and Magisk Manager all working exactly how they should be. I could toggle root and play Pokemon GO, then return to a rooted state when I needed to.
"Awesome, mission accomplished." I thought. Now I just need to toggle root off, download the latest OTA and install it through Flashfire.
First I made a complete nandroid backup (as I've done with other devices many times before) through TWRP. I even copied the backup folder to my PC in case something went wrong.
Well, this is when the nightmare started.
The first mistake I made was to use Flashfire when it clearly stated that Oneplus devices were currently untested. Not sure if it was a big issue or not, but it was a mistake none the less. The second mistake I made was to not stop the stock recovery being replaced when prompted before the reboot. I assumed (and it even states in the app) that the custom recovery should be reverted back to the stock recovery when attempting to apply OTA updates.
So I went ahead and rebooted, waiting for the OTA to install. I'm fairly sure from memory that it went into the stock recovery, flashed the OTA and restarted.
This is when the phone soft bricked.
"Oh well, that is why I made the backup." I thought.
I reflashed TWRP in fastboot mode and attempted to restore my backup. No dice, the phone was still soft bricked.
(And by "soft bricked" and "boot looping" I mean the Oneplus logo was in the middle of the screen, "Powered by Android" was at the bottom and the two blue LEDs for the buttons either side of the fingerprint scanner/home button remained on. This for me was the tell tale sign of the soft brick because these two light go off after a few seconds after rebooting usually.
So from here I have tried EVERYTHING. All I really want now is a working stock (rooted) Marshmallow rom with TWRP. I have downloaded many different full rom zips and attempted to flash them through TWRP with no success, I have returned to stock recovery and tried flashing signed roms with no success, I've even tried flashing the official CM13 rom for Oneplus 2 (with the correct GAPPs and kernel) through TWRP with no luck.
But here is where it gets interesting......
There are a few things that are really weird...
1. I have always been able to get into Fastboot mode and ADB and Fastboot commands "work".
* Operations succeed but don't stick (for example trying to flash TWRP versions 3.0.2-1 and 3.0.2-2 through Fastboot mode result in no recovery being there at all.
2. I can flash TWRP recovery though Fastboot mode but ONLY VERSIONS 3.0.2-0 and lower. I can also successfully flash the stock recovery.
3. I can flash OxygenOS 2.2.1 but NOT ANY VERSION RELEASED AFTER THAT. Doing so results in the soft brick "bootloop" I mentioned earlier.
4. Attempting to flash the official CM13 rom for Oneplus 2 doesn't work either. Originally I got the error 7 message, but after editing "Updater-script" in the rom and re-zipping, the process seemed to work fine in TWRP but the reboot gave me... you guessed it... a softbrick.
I have flashed custom roms on a few different devices before so I'm not a COMPLETE newbie when it comes to this stuff, but I am by no means a developer or even anything close to one. I have bricked this phone in the past (long story, involved getting it without an invite and it being shipped to me with spyware on it) but I used a guide very similar to this and it worked a treat.
www(dot)androidbrick(dot)com/unbrick-oneplus-one-two-3-qualcomm-hs-usb-qdloader-9008
So, thinking that this process would format all partitions and start me from scatch I tried it. It worked fine but I was still unable to upgrade from Oxygen OS 2.2.1 or install TWRP versions 3.0.2-1 or 3.0.2-2.
I have tried all sorts of things. I have wiped, flashed and wiped again. Factory resets, dirty flashes, clean flashes.... everything. All sorts of different sources for the TWRP images and Oxygen roms... nothing seems to work.
It's just so weird considering it's not a hard brick... just a soft brick.
So I really need my phone so I am sitting on this current build because it is the only one that works.
Here are some details of the current build I am using. (using CPU-Z app)
Model: Oneplus 2 (ONE A2001)
Android version: 5.1.1
Oxygen OS version: 2.2.1
Bootloader: Unknown
Build ID: ONE A2001_14_160226
Java VM: ART 2.1.0
OpenGL ES: 3.1
Kernel Architecture: aarch64
Kernel version: 3.10.49-perf+ (56)
Root access: Yes
Super user app: SuperSU Free v2.46 (Chainfire)
OEM unlocking: Enabled
USB debugging: Enabled
And these are some of the ZIPs and IMGs that refuse to be flashed to my device.
TWRP-3.0.2-1-oneplus2
TWRP-3.0.2-2-oneplus2
Grarak's TWRP recovery IMG for Oneplus2 (modified to install CM13) according to this guide:
missingtricks(dot)net/oneplus-2-official-cyanogenmod-13
cm-13.0-20160924-NIGHTLY-oneplus2
OnePlus2Oxygen_14_OTA_019_all_1606041303_bd42fc5cc5cc4ab2
And also my TWRP backup named 2016-09-16--09-44-09
I am really at a loss as to what to do next. ANY help ANYONE could give me would be greatly appreciated. I have been all over the net looking for ways around this bt have had no luck.
As I've said, I'm not a huge tech head, but I'm not a newbie either. The only thing I can think of is that somehow one of the partitions (maybe boot? ) may have been corrupted somehow when messing around with systemless root. But I don't know how considering it's "systemless". If anyone knows how to check for corrupted partitions on the Oneplus 2 please let me know and I'll try it. Maybe formatting these partitions might help (????), but I don't want to permanently brick my phone.
But I don't know how I've got this particular build working if one of the partitions has been corrupted. And the corrupted partition thing is just a guess.....
Please, anyone, someone point me in the right direction. Again, any and all feddback is welcomed and would be very much appreciated.
This is all Pikachu's fault.

The normal way too update from OOS 2 to OOS 3 is:
Flash the OOS 3 signed flashable zip via TWRP to update the bootloader and firmware
Flash TWRP 3.0.2-2 via your current TWRP's recovery image flashing option
Reboot recovery via TWRP so that you now have a recovery that's compatible with the new bootloader
Wipe data, cache & dalvik-cache (but not internal storage)
Flash the OOS 3 signed flashable zip again to update the system
Flash one of the modified SuperSU zips if you want root
Reboot system
All the files you need are in post #1 of this thread.

Thank you so much Spannaa!
I was clearly missing a vital step here and let it be a lesson to anyone else in this situation....
As Spannaa said......
1. Flash the OOS 3 signed flashable zip via TWRP to update the bootloader and firmware
2. Flash TWRP 3.0.2-2 via your current TWRP's recovery image flashing option
3. Reboot recovery via TWRP SO THAT YOU NOW HAVE A RECOVERY THAT'S COMPATIBLE WITH THE NEW BOOTLOADER!
4. Wipe data, cache & dalvik-cache (but not internal storage)
5. Flash the OOS 3 signed flashable zip AGAIN to update the system.
Again, thankyou Spanna for your quick and accurate response.
The order in which you flash zips and imgs is very important it seems.
You really saved me.
I restored the TWRP backup and I am back to where I started.
Is it now possible to apply OTAs when I toggle the root off in Magisk manager and install using the stock recovery? What do you think would be the best way to do this?
And would it be worth moving to the official build of CM13 for Oneplus 2?
Thanks again, Spannaa. :victory:

Glad you're sorted.
Not sure about Magisk as I've never used it.
CM13 is OK but whether it's worth you moving to it is your choice. Personally, I prefer TipsyOS!

Hi,
I face the exact issue with same Oxygen OS and TWRP versions mentioned, I have tried the above steps but there are some problems:
1. Flash the OOS 3 signed flashable zip via TWRP to update the bootloader and firmware

when I checked the option (Zip signature verification) in TWRP, the installation failed with error "Zip signature verification failed! Error installing zip file '/sdcard/oneplus.zip'", but it's successfully installed when I unchecked (Zip signature verification) option.

3. Reboot recovery via TWRP SO THAT YOU NOW HAVE A RECOVERY THAT'S COMPATIBLE WITH THE NEW BOOTLOADER!

second problem is that after installing the TWRP 3.0.2-2 (or above), then reboot recovery, I can't access the recovery again and the phone stuck on bootloop.
any idea ?

I don't have a OP2 anymore but that post was seven months ago and the instructions worked for numerous users.
Don't enable zip signature verification in TWRP - it's unnecessary.
Flash TWRP 3.0.2-2 via your current TWRP's recovery image flashing option and then reboot recovery directly from TWRP.

thanx for replay Spannaa,

I have already did that, but same issue once I reboot "directly from TWRP" , the TWRP doesn't show up and bootloop start again.

Last chance and then I'll leave this for someone that has the OP2.
Are you rebooting recovery "directly from TWRP" or rebooting system?
Is your bootloader still unlocked?

Yes, rebooting recovery "directly from TWRP"
and bootloader loader is unlocked,..
anyway it's not important to fix the phone, it's almost one year since last time I use it, yesterday I saw it in the drawer and try to figure out the issue..,

TWRP bootloop after flashing TWRP Solved

Don´t know if anybody had this kind of Problem before. Couldnt find anything.
Was on Stock V image with cutom kernel flashed via fastboot and SU flashed via fastboo boot to root.
Problem:
bootet TWRP via fastboot with newest drivers. Flashed RC via booted TWRP.
Wanted to reboot system, but was stuck in a TWRP bootloop. No chance to boot into bootloader also. Even tried changing slots in twrp but still only bootloop to twrp.
Than I thought about sideload because that's what I did with latest ota image from Google.
Here is what I did:
sideloaded the ota.zip via TWRP from PC "adb sideload ota_file.zip" ota_file should be the name of your ota file
It gave me an error, but after rebooting system all fine again. Back to stock V and bootloader is there again.

Easier thing to do is flash boot.img from the factory image to boot_a and boot_b if you are having issues.
This problem occurs when you flash TWRP if you have root installed. To avoid, remove root before installing TWRP.
Oh, I should mention to get into bootloader from TWRP, simply use the adb command "adb reboot bootloader". Should work, worked for me.

I just have avoided flashing TWRP altogether. I rarely need to flash anything, so it can wait until I am at work or home to use a PC to BOOT TWRP each time I need it, instead of flashing it.

Until it gets a little more stable on the Pixel, this is probably a good idea.

Good idea. But I M sometimes flashing when I am at or on the way to work.

I know its already solved, but here is what helps (for future):
Just flash SuperSU (latest Version)
Done. This will patch the boot.img so your phone boots in the OS again.

I have this issue and flashing supersu didn't fix my problem. Will go to factory image flashing.

Thanks! This worked for me.

EDIT: Never mind, I missed the comment guiding ppl to flash SuperSU. I suppose that when this thread was posted, that SuperSU was still being used instead of Magisk, so solution is essentially the same thing I'm recommending.
I think this thread is missing the much easier solution here:
I just ran into this issue with my Pixel 2 XL when I tried to update my TWRP version from 3.2.1-2 to 3.2.3-0. Here's how it went:
1. Downloaded the TWRP zip, md5 and so on from the official TWRP website for the Pixel 2 XL
2. Booted to TWRP and installed / flashed the zip of TWRP 3.2.3-0
3. Wiped dalvik and then chose Reboot to System from TWRP -- the phone booted right back into TWRP
4. Tried again to reboot the same way. Same result.
5. Installed / Flashed the 3.2.1-2 TWRP zip which was still on my phone, in order to revert to the previous version, and then Rebooted to System -- same result
6. Flashed 3.2.3-0 zip again, then flashed the Flash Kernel that I've been using, and then Flashed the Magisk v16.0 zip that I used to root, then chose Reboot to System -- AND IT WORKED; the phone booted normally and now I'm updated to the latest TWRP successfully.
tl;dr - The solution is to flash Magisk again after updating TWRP. Pretty sure this goes for kernel updates too.

Aren't the two systems (Pixel OG and Pixel 2) extremely similar? If they're not, then my advice should be ignored for anyone using the Pixel OG.

No OS installed. TWRP cannot flash new custom ROM

Hello,
I have a big problem. I don't know what to do.
I wanted to make a clean install of OxygenOS 4.5.8 and so i downloaded it, did it on SD card together with Magisk and no_verity_op5.zip (because i read that this decrypt the data).
So i cleand data and installed no_verity_op5.zip via TWRP, but when i wanted to reboot it takes way to long (i waited 30minutes but it stays on boot circle)
After that i booted into TWRP and decided to made a factory reset and to install OxygonOS 4.5.8 in a clean version. But it was not possible anymore!
When i want to install the .zip it says Patching system image unconditionally... and it loads. after the blue is full it says:
writing static_nvbk image...
patching firmware images...
script succeeded: result was [1.000000]
And when i want to boot into system it says no OS installed.
I tried also to flash this rom or even any other custom rom through ADB Sideload but it does not work. Same like above..
What can i do? I do not know what to do
I hope my phone is not bricked.
Thank you for any suggestion.

Go to oneplus 5 official download page, download stock recovery and latest stock firmware and follow instructions on the download page.... But first with TWRP take a backup of all your data because restoring stock firmware will ERASE everything... Don't panic it will works

First off, don't panic! you're not bricked as long as you can reach your bootloader and recovery.
This happened to me as well and luckily the fix is easy!
You probably tried to flash the OxygenOS build from the Oneplus downloads right?
Somehow these won't flash properly through TWRP and you must therefore also flash the Oxygen recovery image listed in the downloads.
Here are some steps that'll fix your problem.
1 - Backup all of your private data from internal storage because flashing OxygenOS will WIPE/ENCRYPT all data on your device.
2 - Go to the Oneplus download center and download both the latest OxygenOS and it's appropriate recovery:
http://downloads.oneplus.net/oneplus-5/oneplus_5_oxygenos_4.5.8
3 - Boot into your bootloader and flash the stock recovery you just downloaded. (fastboot flash recovery <recovery>.img)
4 - Boot into the Oxygen recovery and flash OxygenOS.
This should get you up and running again.
Once you get tired of OxygenOS simply reboot back into your bootloader and flash TWRP and any rom of your liking.
In the future if you want to flash OxygenOS from TWRP you have to grab a build from XDA I guess. I'm not entirely sure why flashing from within TWRP won't work with stock OOS but I believe it expects to be flashed from withing the stock recovery.
I'm pretty confident this will solve your problems.
Please backup your data first though, don't want anything to get messed up in there!
Good luck!

Ok thank you.
i will try it.
So you are right, i tried to install OxygenOS with TWRP.
So is it not possible to have official OxygenOS with TWRP, Magisk and Root?
So i cannot backup OxygenOS with TWRP?

It is possible to have both OxygenOS and TWRP for sure!
Only a clean flash from a non-encrypted state in TWRP seems to break stuff. You can use a modified OOS build from the forums.
TWRP can indeed backup your OOS install so that shouldn't be a problem.
The only exception seems to be flashing a clean install of OxygenOS (from Oneplus Download center) through TWRP.
Other than that everything works as expected.

Ok thank you.
So i will follow you instructions and i hope it will work.
And i think so.
And after it i will install TWRP again (because i need the backup tool), i will install magisk. will this work?
So i can use everything as in a custom rom, but cannot make a clean install? So official Oneplus OTA will work with TWRP or not?
Thank you soooo much!

Also, Magisk/root works just fine on OxygenOS.
Once you flashed OOS from the stock recovery and have everything set up simply boot into your bootloader and flash TWRP.
From there you flash Magisk and everything should be fine.
OTA's from Oneplus also install fine through TWRP as long as you go into Magisk and uninstall 'root' first. When OxygenOS tells you there's an update simply remove Magisk as I said above and it'll update fine.

Ok thank you!
It worked!!!!! I am very happy!
So i will now install TWRP, and then magisk (newest version).
I have a question, because the last time i installed magisk it did not fully work.
If i install it i have root or? But how can i get saftynet in magisk?

First off! YAY!! glad it worked out!
Be sure to use the TWRP build from the twrp.me website. The one listed on these forums are 'unofficial'. Not saying those are bad, but the official one has a pretty impressive track-record.
After flashing Magisk you are root-enabled so yeah, congrats you are now root! In order to pass safetynet you must enable 'magisk hide' in the magisk manager (the app that should now be installed on your phone).
If you do not have an app called 'magisk manager' then you can download this app from the magisk forums. It should however install itself while flashing the Magisk zip. So assuming you have it installed find the 'magisk hide' service and enable it.
From my experience you sometimes need to reboot in order for it to pass safetynet check.
Glad it all worked out for you!

Everything worked!
Now i have OxygenOS 4.5.8 (with OTAs in future), magisk + root + saftynet and i can install something throug TWRP and backup.
SO PERFEKT.
You are a hero

Can't you just connect your phone to your PC and use MTP for the file transfer? Make sure to have MTP disabled under TWRP-> Mount -> Enable MTP

ZE520kl OTA upgrade doesn't work

Hi,
I've downgraded my phone ZE520KL couple months ago but I've forgotten that VOLTE is only available on 7.0...
I've recieved the OTA notification, downloaded the package on the phone, but when it reboots it is going on TWRP & then if I'm rebooting it doesn't continue the upgrade process.
What am I missing? (on my previous phones this wasn't so tricky...) Should I use the Install method directly from TWRP? If Yes on which zip? Is it possible to find the one that I've downloaded directly with my phone?

Same like me before. Have you rooted your phone yet? if yes then try this, it work for me though (Backup your phone is recommended)
1. Download busybox, supersu and no-verity file
2. Using flashfire app, choose flash zip or ota option
3. Add ota 'WW-ZE520Kl-.....'
4. Add firmware 'UL-ASUS-....'
5. Remove tickmark from 'Inject supersu'
And flash, it will reboot but do not boot to system. You must boot to twrp, flash no-verity file, busybox and supersu or your phone will not boot. Then reboot, done.
If this method is helpful, do reply to me
Btw, sorry for my poor english.

Thanks, works wonderfully! Flashfire flashed the new OTAs successfully but the phone didn't then boot (or it bootlooped). A quick Google search led me to your response and the dm-verity file fixed the boot!
I also didn't flash Busybox in case you needed to know and before flashing the OTAs I checked the "Automount" and "Mount systeam as R/W" in Flashfire otherwise the app would just get stuck in a blank screen.
EDIT: WiFI isn't working, tried already deleting the files in /data/misc/wifi, /persist and /data/misc/dhcp as suggested in various threads but still nothing. Anyone know how to fix it before I attempt to do a full backup and wipe?

Deleting files in /data/misc is not helped. Try this:
1. Check your selinux permissive or enforcing. If permissive, you should re-root your phone. Remember to flash busybox too or it will may some crash. Still not working follow step 2.
2. Re-flash the ROM using twrp. No data will be lost. Don't forget to re-root or it will not boot.
3. Try the lastest fw .68 or .75 though someone told that the .28 ota file had issue on wifi.

Reflashing through TWRP worked Although I did it after backing up all the apps and did a factory reset which didn't even fix the wi-fi problem. But then Flashfire is useless if TWRP is capable of flashing OTAs right?

Not really. Since OTA file can't flash through twrp. It really annoying for someone (like me ), so for the easiest way is just flash it using Flashfire, no need to use computer to flash stock recovery .

@vEEGAZ
yep, that's what I've been saying for months. I've never used anything but TWRP to flash my phone. I've downgraded, gone custom and back to stock many times.

I flash OTA's through TWRP every time there's an update.

Yeah that's what I encountered aswell back 2-3 years ago, I remember I couldn't flash any OTAs via TWRP but apparently now you can. That's why I also used Flashfire in the first place but after running out of all options for the wi-fi problem I decided to give TWRP a try et voilà, it worked

I JUST did it....on 1711.75 now. There was no recovery partition update either so I didn't have to reflash TWRP after :good:
I did have a bootloop issue after but fixed that by flashing the no-verity file. I'm not sure if that's related to having magisk installed though.

1. After reflashing rom through twrp, i lost my twrp. Oh, but when i use Flasfire, it isn't lost.
2. Not sure but after flashing ROM your boot will change to normal so it may not related to magisk or supersu. Maybe it beacause of the twrp, i've tried reflash stock recovery once and i can updated it without flash no-verity file though i've installed magisk.

1. You will only lose TWRP if there is a recovery partition update in the stock firmware, yes, but that doesn't happen with every update. I think I read of a way to block it from updating the recovery partition but can't find the article right now. If flashfire works, use it, I just like TWRP for the other features like making and restoring nandroid backups.
2. I dirty flashed the update again through TWRP, verified the bootloop issue and then installed magisk (through TWRP) and it resolved the bootloop issue. No-verify file not required.

1.Ok, i got it.
2. The way using TWRP is keep the root ( root or not boot) and stock recovery is contrary ( can't root but will boot) or just flash custom kernel through twrp (not root required).

simple question :
- you are talking about OTA & Firmware...
I've downloaded again from asus website Version WW-V14.2020.1711.75 (I assume it is the latest firmware). Are you simply giving the example of an OTA that is released post the firmware version I have to install to have the 7.0 base?
Or is it anything that I'm missing...
From your explanations I should only :
- install flashfire
- flash the latest firmware
- boot into TWRP & flash no verity
- reboot the system
Right?

Yep, you can also flash the latest .zip via TWRP instead of using Flashfire, it's 100% working for me. Just REMEMBER to flash the no-verity file otherwise you'll end up in a bootloop.

I have newest oreo fw from asus website. Ive unlocked bootloader with official app. Now i want WTRP and root with magisk. I want to know how to flash updates to get all wroking?
1. Flash TWRP via fastboot?
2. Flash Magisk via TWRP?
3. When update will release i must flash whole fw from asus website with TWRP and then no-verity file to boot?
4. Or can i use flashfire app to flash fw from asus website and then no-verity zip?
What is the best solution to have updated system without use PC? Step by step guide will be great THX

The safest and true way to flash any ota update without any issues by using stock recovery, don't use twrp or flashfire or any other apps.
follow the steps below:
1. When you are rooted and twrp installed, to getback to full stock boot and recovery without wiping data, flash the latest raw image available. For oreo the latest available one for ze520kl is WW_ZE520KL_15.0410.1712.31_M3.10.47.16_Phone-user.raw.zip.
2. Now flash the ota update available normally via stock recovery.
3. Flash oreo support twrp-3.2.1-0 and magisk zip.
4. Done.
I'm periodically upload the latest available ota update for ze520kl in the ze520kl ota update links thread.
Here is the latest one.

What is update process for OP6T 9.0.16 > 10.3.3 rooted [Global]

I have OP6T OxygenOS 9.0.16 and I would like to update it to the latest 10.3.3 with root.
What should be my process of doing so? I have not been in touch with rooting for the past 3 years so I don't want to mess things up. Another note is that while I am on OxygenOS 9.0.16 I tried to root it which was failed, but now few banking and calling apps such as TextNow thinks that my phone is rooted and they can not run -- but my phone is not properly rooted according to root verification apps.
Please tell me how should I do the update to the latest version from this point and then I would like to unlock bootloader and install recovery and root it as well.
Please advice.
BTW my OP6T is global

Flash OOS full rom zip on both slots using TWRP also flash TWRP installer zip on both slots reboot recovery flash magisk reboot system. Easy peasy.
Example:
Boot recovery: fastboot boot twrp.img
flash OOS 10.3.3 full rom zip
flash TWRP installer zip, reboot recovery,
flash OOS 10.3.3 full rom zip, format data, wipe data,
flash TWRP installer zip
Reboot recovery, flash magisk,
reboot system.
Note: I use a USB stick. I flash magisk zip off my USB stick.
That's what I do when I use OOS on my 6t far as installation goes.

Are you sure there is no need to update to 9.0.17 and then 10.3.3?
I've asked once and someone said that 9.0.17 is neccessary before update to 10.3.x.
Also there is option to flash from system without losing magisk modules:
1. Flash manually from update center (do not reboot)
2. Enter magisk and flash to another slot (after OTA)
3. Flash TWRP installer like magisk module
4. Reboot
But I'm not sure if I remember it correctly.

10.3.3 is all that you need. 9.0.17 isn't the only way anymore.

I have a T-Mobile SIM unlock OnePlus 6t and I converted it to an international model so when my conversation was done I was on OOS 9.0.1.1 and I booted TWRP and installed 10.3.4 full rom on both slots and also recovery installer and all just like my previous posts stated and everything went fine. I used mauronofrio's TWRP the version just before the latest 3.4xx when I did this.
I always download quite a bit of various firmwares and also TWRP versions before I start flashing things just in case something goes wrong I already have other things maybe I can use and I don't have to stop and wait for some download to finish... And I'm quite sure you know this but definitely make a backup of everything beforehand to USB or transfer it to your pc just in case you end up needing it as a precaution.
Edit added:
I am assuming that you already unlocked your bootloader... I believe everyone knows to do that that's on XDA forums before you can do anything to any device .. I say this after reading post below me here. I guess I should have said that earlier but I just assume everyone knows that on the forums... My bad. ??
From fastboot on Linux PC:
sudo fastboot oem unlock (then hit enter on keyboard) use volume keys to move to unlock option and your Power button to select it and confirm. For more info see: https://www.xda-developers.com/oneplus-6t-unlock-bootloader-root/
Super easy to unlock bootloader just remember it does wipe your device clean so move anything to want to PC or USB stick first...

I would think you could just update oxygenOS to latest then re-root no? Assuming your already bootloader unlocked which it seems like would be the case if you have an obsolete magisk installation.
Edit: re-reading your post maybe it is not unlocked as you failed to root. In this case just unlock then flash the latest fastboot image and then magisk as others have already stepped you through. You will lose data when you unlock so backup first.

So if I'm on 9.0.16 I could flash latest OOS directly from TWRP and then flash magisk? And no data loss? Of course I'm rooted with bootloader unlocked.

Oh dear this process is getting harder because recently I was busy doing other things it sounds way harder it actually is. Isnt there a way I pay someone on this forum so that user help me do this. Like download stuff links and proper version and follow me up with it because i want to do this without messing things up!

It is indeed a tough job. This A/B partition has had a lot of people bootloop/soft bricked their phones.
However, you need not pay anybody anything. If you are on stock, I would've recommended you upgrading it via Oxygen updater (a 3rd party app on the play store) and then using the latest recoveries (TWRP 3.4) and flashing it via Fastboot mode.
It is super easy.
