The benefits of doing both slots is less tripping yourself up later when you want to flash something else and you end up getting confused as to which slot has what, it's not a serious problem for most people and if you're running smoothly then you're running and I wouldn't worry about it. The theoretical intent of having an A and B slot is that your device never runs anything other than Over The Air updates so when a local upgrade is performed a "backup" slot of your old OOS is retained in the event that the upgrade somehow gets interrupted or corrupted. Your device can then fall back on a stable build to try from again. The idea of keeping both of your slots identical comes from the fact that a lot of us are going back and forth from so many different stock and custom operating systems as well as different security patches that it just essentially "eliminates as much room" as possible for there to be a problem and then if there is a problem it can be more easily recognized and troubleshooted.
[OnePlus 6T  Guides, News, & Discussion] badpanda:
Can I do both slots now afterwards?
[OnePlus 6T  Guides, News, & Discussion] Causical:
You can if you would like but if you are running OOS 10 rooted and with TWRP already you should be fine. Although if you insist you would simply boot back into TWRP flash OOS 10.0.1 again, flash TWRP, flash Magisk again (because TWRP just overwrote it) reboot recovery then flash Magisk once more and reboot system. Assuming I read your previous post correctly and you already have one slot flashed to OOS 10.0.1, this will get it flashed to both slots.

magisk and bust...

So...I've gone through 'method 3' twice now.

the first time, once I installed magisk for root my phone basically stopped working...no sound, no phone calls, freeze ups, fingerprint didnt work, etc...

after fooling around with it and using the all in one tool i could get it back to what ever stock rom i wanted. I proceeded to put A10.0.1 back on and everything with the phone was back to normal, except no root and stock recovery.

once in stock recovery I went through all the steps again and got TWRP with encryption working fine. But the same thing happened when installing the magisk zip (20.1) through twrp (3.3.1 - 28), phone stopped working.

Is there a step that i'm missing?

~~~~~~~~~~~~~~~~~~~~~~ Method-3 ~~

OOS 10.0 [UNROOTED] to OOS 10.0 [ROOTED]

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

~. *Step 4 will boot into TWRP and *Step 7 is to Keep/Install TWRP

~. To Reset Rooted "OOS 10.x" go to TWRP >> Wipe > Swipe to Factory Reset > Steps 6 to 10

1. Unlock Bootloader >> [Skip Setup wizard steps] >> Reboot to Recovery (Stock Recovery)

2. Stock Recovery >> "Wipe data and cache" > "Erase everything" > Reboot to Bootloader

3. Fastboot >> Command: fastboot flash boot "FILE-4"

4. Fastboot >> START

5. TWRP >> Switch slot > Reboot to Recovery

6. TWRP >> Flash or adb sideload "FILE-5"

7. TWRP >> Flash or adb sideload "FILE-2"

8. TWRP >> Switch slot > Reboot to Recovery

9. TWRP >> Flash or adb sideload "FILE-1"

10. Reboot to System

If your bootloader is already unlocked then you don't need to wipe. The wipe is only necessary because Android enforces it as part of the unlock process. The idea is that if it's someone nefarious unlocking your bootloader then they can't get your personal data.

From 10.0.1 rooted to 10.3 rooted

1. Flash latest full OTA via Local Updater [DON'T REBOOT]

2. In Magisk Manager, flash latest TWRP installer zip from mauronofrio [DON'T REBOOT]

3. Still in Magisk Manager, Install (next to "Magisk is up to date") > Install > Install to inactive slot

4. Reboot

I also use XxX NoLimits and this method keeps all your Magisk modules enabled.

For you its 3A only

---------- Post added at 03:02 PM ---------- Previous post was at 02:58 PM ----------

Sure !
[OnePlus 6T  Guides, News, & Discussion] Alqaszar:
Indeed I used the rainy weekend for experimenting.

I went from 9.0.17 rooted to 10.3.0 rooted, which basically went well.

The following happened:

1. I let the phone do its regular OTA process with TWRP installed and the A/B-retention flashed from Magis manager.

2. Before rebooting, I went into Magisk Manager and chose "Install to inactive slot".

3. Reboot.

Result was a rooted 10.3.0, but TWRP was gone. Which was no problem, since I could install it from Magisk Manager.

Now I had TWRP on recovery, but no more root.

So I booted into TWRP and flashed the Magisk ZIP.

Now I got my phone on 10.3.0 with TWRP and Magisk root.

However, if TWRP is not needed for other reasons, it should be possible to keep the device rooted through the "install Magisk to inactive slot" option during OTA. In this case, everything would work fine without TWRP on the phone. Even if the A/B-retention ZIP does not properly work through the regular OTA process, root will be preserved, and with Magisk, it's always possible to flash TWRP. (Beside the fact that TWRP.img can be flashed to boot)

The question is if the Magisk ZIP will be working with future Oxygen OS versions based on Android 10, so keep looking for updates.
[OnePlus 6T  Guides, News, & Discussion] jp0469:
Yeah, I don't trust that A/B retention script anymore. For future reference, all you needed to do was:

Local upgrade using the full OTA (Don't reboot)

Install TWRP using latest zip in Magisk as module (Don't reboot)

Install Magisk to inactive slot

Reboot

All Magisk modules remain active using this method. Also, the step to re-install TWRP is optional if you don't need it. I personally like to keep it since it gives me additional options in the event of a problem later.

[OnePlus 6T  Guides, News, & Discussion] plepew:
Hey guys,

So I have done the following in the past under PIE up to (9.0.17) and it was the easiest thing in eight steps and always worked like a charm. (6T McLaren Edition)

0.0 Remove Substratum & Security (Password) on the device before starting this process

0.5 TWRP FULL NANDROID BACKUP & Reboot into TWRP again for good measure

1.0 Now in TWRP Flash the Latest Magisk Uninstaller

2.0 Flash the latest Full Oxygen OS Zip

3.0 Flash the TWRP installer Zip

4.0 Reboot to RECOVERY to make sure TWRP stays and continue to root.

5.0 Flash the Latest Magisk to maintain root

6.0 Reboot System and Enjoy the latest firmware without any data loss

Now I'm currently on OOS 9.0.17 [ROOTED] AND THE DEVICE WORKS PERFECTLY :

TWRP 3.3.1-6-Fajita

Magisk 20.1

Magisk Mgr 7.4.0(253)

I would like to confirm if I was to do the same process above with the updated files (itemized below), will it work properly? I ask as I am comfortable with this process.

Will this process/method work to get to OOS 10.3.0 [ROOTED] without issue(s)?

0.0 Remove Substratum & Security (Password) on the device before starting this process

0.5 TWRP FULL NANDROID BACKUP & Reboot into TWRP again for good measure

1.0 Now in TWRP Flash the Latest Magisk Uninstaller

2.0 Flash the latest Full Oxygen OS Zip (OOS 10.3.0)

3.0 Flash the TWRP installer Zip (TWRP 3.3.1-30 Q)

4.0 Reboot to RECOVERY to make sure TWRP stays and continue to root.

5.0 Flash the Latest Magisk to maintain root (Magisk 20.1)

6.0 Reboot System and possibly enjoy the latest firmware OOS 10.3.0 [ROOTED] without any data loss?

To some, this may seem like taking the long way to achieve the 10.3.0 rooted, but it's a process that I am really familiar with. I have been very weary with all the different approaches & processes which some seem to be unsuccessful & create more issues and others with some additional tweaking get it done and some just plain success.

if you PROS out there can assist in confirming, advise or correct me if I am missing a step, I would appreciated.

PS. I tried to visualized Method 2 on my phone, but I am really not familiar with Magisk Modules and getting this install done in this manner. If it is the only way to get it done, I will do it...but I am very fearful of the end result...yeah, I know somewhat of a little chicken, I am...LOL!)

I can't afford to fail on the update as there is critical info on this device (2 SIMS) Work & Personal. (Yes everything is backed up, but to restart setting up the device from scratch is super painful :(:crying: as some of you already know! ;) LOL

Thanking you all in advance for you patience and help!!:o:good:

I was on 9.0.17 rooted with TWRP and the below is a much simpler way in which I upgraded to 10.3.0 rooted with TWRP installed. No need to remove passwords, no need to disable modules. I just uninstalled my substratum theme and rebooted before starting.

1. Flash latest full OTA via Local Updater [DON'T REBOOT]

2. In Magisk Manager, flash latest TWRP installer zip (the one called unofficial installer) from mauronofrio [DON'T REBOOT]

3. Still in Magisk Manager, Install (next to "Magisk is up to date") > Install > Install to inactive slot

4. Reboot

Ok, so I did it, now Wi-Fi is completely dead
[OnePlus 6T  Guides, News, & Discussion] zickler_malta:
I didn't have that problem but it seems to be common. An easy way to fix it is to flash a custom kernel. I would recommend Omega. It's a great kernel and dev has swapped out all the WiFi code from oneplus to that of the Pixel 3 since he said it was a mess.
[OnePlus 6T  Guides, News, & Discussion] plepew:
This is ridiculous cause I just received the 10.3.0 OTA thinking it was fixed... I don't want to mess with Kernels and all that. As I mentioned I need this device working 100% due to work.

I need to go back to my 9.0.17 setup. ?

With the TWRP Q, I won't be able to go back to it...or is there a way to restore my Nandroid I did before doing the update?
[OnePlus 6T  Guides, News, & Discussion] zickler_malta:
I was on 9.0.17 and went to 10.3.0 and didn't encounter that problem so it must be something from your side. Flashing a kernel will take you 5 seconds in TWRP, you don't even have to re-install Magisk and you will avoid risking bricking your device and losing all your data.

[OnePlus 6T  Guides, News, & Discussion] jp0469:
Well given your situation, here's what I would suggest.

Boot into recovery (TWRP)

Flash the latest Magisk uninstaller: https://github.com/topjohnwu/Magisk/releases/tag/v20.1

Re-flash the full Android 10.3.0 OTA

Still in TWRP, re-flash the TWRP 3.3.1-30 installer zip

Reboot directly back to TWRP

Flash the latest Magisk zip

Reboot

Thanks a ton.....your suggestion worked flawlessly!
[OnePlus 6T  Guides, News, & Discussion] plepew:
Ok, I was entertaining changing the Kernel you suggested . But I really wanted to stay on stock for most of all of the OP rom, except TWRP and adding Magisk of course .

So after searching and reading quite a bit of threads XDA & OP Forums, I figured out what the issues were:

1- After the update, all was working good...the device needed to settle. But when this update (10.3.0), it changed my MAC address!!! ? I found this to be really weird, cause I really thought MAC addresses were actually embedded in the hardware. So I added this to my MAC filter on my router. Boom, connection to 2.4 & 5.0! ☺️?

2- Not so fast...☹️ Now the connections would drop intermittently and for no reasons as I was about 10 feet away from a router (2 in the house). This was more frustrating than no connection to Wi-Fi due to all the possibilities / combinations of issues... It turns out, OP added a Privacy feature, which is the default setting when you make a Network Connection Profile to connect to Wi-Fis.

Under a Wi-Fi Network Details, hit Advanced, then go to Privacy, there are 2 options: a) Use randomized MAC (default) & b) Use Device MAC.

I choose "Use device MAC" for my setup (MAC Filtering) and boom! All is well.

PS. I was at my parents yesterday and had their home profile, I connected right away. (No MAC Filtering setup).

Hope this helps others!!

A very big thank you to Zickler_malta & all others who have helped!! ??

Cheers!!

ehrm... after fallowing the instructions 10 > 10, I no longer have access to any of phone storage? I've checked in the files app, which shows "109 GB free" and "Can't load content at the moment"... Everything else seems to have worked correctly, i.e TWRP permanently installed, system installed (obviously), root access achieved. Not entirely sure what I missed/did wrong. I was really hoping I could somehow get the update zip from Oneplus loaded up, thinking that might fix the issue (I had a few weird issues when I updated to from 9 to 10, and this fixed them all for me), but without any access to my file structure, this is difficult. In TWRP, I can see and access my /sdcard, and all that is in that dir is "obb" and "TWRP". Any ideas would be great! Thanks!

First thing, what version of TWRP is installed?

You need to be on TWRP 3.3.1-30. If you're not, I would install 3.3.1-30-fajita-installer-mauronofrio.zip asap. Reboot back TWRP to make sure it sticks, and reinstall Magisk 20.1. This may resolve the issue. Seems like it's encrypted and this is why it's not showing up. Just an idea at first glance of your post^
[OnePlus 6T  Guides, News, & Discussion] kadivadavidak:
Thanks for the reply!!

That's the exact conclusion I've come to - For some reason it's not decrypting. I'm on 3.3.1-30, and have from the beginning, so not sure what's going on. I've gone back and forth through the steps trying everything I can think of, to no avail. Sometimes it will ask for my decryption password, and it will be fine, then I'll reboot into TWRP, and it wont ask, and it wont be fine. I just want my phone back...

Best I can surmise is I installed Magisk on the wrong partition. Reinstalling (after attempting most everything else over and over) seems to have fixed it! I have a usable phone again on latest OxygenOs and Root! I'm happy now! Thanks again!

I thought I was in the clear. No go.

When the instructions say to switch slots, is there a specific slot I should be on in each step? Or does the slot not really matter as long as I do indeed switch slots? I.e, should I begin in slot B or slot A?

Using https://xdaforums.com/oneplus-6t/how-to/guide-oneplus-6t-unlock-bootloader-t3851789, I was able to get it going.

Used this to go back to latest (10.3.0) stock https://xdaforums.com/oneplus-6t/how-to/rom-stock-fastboot-roms-oneplus-6t-t3862516 (since I had already bungled it all up, I needed to go back to fresh stock)

I had to locally update to latest (10.3.0) as well. I had some weird stuff going on without this step like emojis and other special character weren't available for some reason...

Only because of the above, do the following (Must be done before continuing):

* Copy update image to root of local storage (Found on Oneplus website)

* Setting >> System >> System Updates >> Settings icon >> Local upgrade >> Select update image >> Install now

* Reboot system

***

Enable Dev options

Enable USB debugging

Double check OEM Unlocking is still checked

Copy Magisk and TWRP installer to device

Boot into fastboot

On computer run

fastboot boot twrp.img

Wait to boot into TWRP (temp)

TWRP >> Install >> TWRP installer zip (perm)

Reboot recovery

Swipe to allow mods

TWRP >> Install >> Magisk

Reboot system

I'm on OOS 10....or was at least. As of now I can't boot into stock TWRP or stock recovery, (OOS won't boot either).

This wouldn't be a big deal if I had TWRP installed. But I can't seem to get past the FastBoot mode and into TWRP.

Powershell command (from desktop):

fastboot devices

Fasboot boot twrp.img

Then the phone switches over to the Fastboot Mode with the oneplus logo in the center and it won't boot into TWRP.

Any thoughts on where I should go from here??

[OnePlus 6T  Guides, News, & Discussion] kadivadavidak:
On your computer, navigate to the fastboot folder (in cmd, run "where fastboot" on windows, or "which fastboot" on Linux/Unix if you're not sure), copy and past the TWRP boot image (not install image) into this folder, and run "fastboot boot [name of TWRP image]". [name of TWRP image] is the full name of the TWRP image you just pasted, including .img (something like "twrp-3.3.1-30-fajita-Q-mauronofrio.img"). That should get you going.
[OnePlus 6T  Guides, News, & Discussion] Lifewithoutdeath:
I did that but it doesn't work. Windows says

"downloading boot.img"

"OKAY"

"booting..."

"FAILED" (remote: unknown command)

My 6T is soft bricked or something, because I was just able to get OmniROM Q installed and running WITHOUT any recovery and vice versa. I can only have one or the other for some reason. The phone won't let me have a custom (or stock) recovery and a ROM at the same time. It's one or the other.

As of now TWRP is where the system ROM should be. This internal sd card partitioning is so ****ed up I have no idea what to do

I mean it can work if you start out by fastboot boot TWRP 3.3.1-30 img and continue from there if you don't already have TWRP on your phone which I assume you do not...

if you got working ADB and fastboot just make sure you have all the proper files on the internal storage of your phone and you should be good to go.
