You don't need to format again or wipe (your step 8).

And, yes, you do need to switch slots so that it's installed over the current OOS. Do not manually switch slots again. TWRP will automatically switch slots when you reboot it after you've installed/sideloaded the new OS.

PS: the OP procedures are correct. Why on earth would you change them (by introducing your step 8) if you don't understand how it works?

@theincognito thanks so much for the Update and Merry Christmas. :)

You should update the download link in the OP as well to this new Version and perhaps remove in the FAQ that the OOS/H2OS flashing is broken as that got fixed now with this new Update.

Great work!

Done. Thank you and wish you the same :D

I've been reading through the thread, and I'm clear on how to install twrp using fastboot. But, silly question, if I'm rooted already can't I Just flash the installer in magisk?
[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] BillGoss:
Yep, that's the easiest way.
[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] Qnorsten:
With the latest version you can just flash the full OOS ota zip and install OOS.

Might need to format data if you come from another rom
[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] dedelamalice:
Merci :)

Is there a possibility not to encrypt the internal storage?
[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] BillGoss:
Just don't add a password or PIN
[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] Ryano89:
So Everytime I boot into twrp I have to delete my pin? I'm currently on a custom Rom with twrp successfully installed but it doesn't see any of my downloaded files when I boot into it
[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] BillGoss:
You asked how too avoid encrypting storage. Removing pin/password removes encryption.

If you have a password, TWRP will ask you for the password so that it can decrypt storage, just like the system does when it prompts you for your password when it boots up.

Now you seem to be taking about something different. I can't see what you're doing/seeing on your phone so you are going to provide more explicit information and/or screenshots.
[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] Ryano89:
Sorry, it wasn't me who originally asked. I currently have a pin set. When I boot into TWRP it does not ask me for a pin though, it just boots directly into twrp. However, if I select "install" for example, there are no files found on my internal sdcard or in storage.i can access those areas, there just nothing there. I can't provide screenshots.

Edit: I should also note that this is probably only my issue because it's an A12 custom Rom. I saw someone post that it worked so I thought I'd give it a try.
[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] Ryano89:
Just for reference to what I'm seeing

@theincognito I just have a short question. Is the latest Version really based on latest TWRP 3.6.0-11-1

for me it seems it is 3.6.0-11-0 .

I have set %tw_version% in the splash.xml file since I use this TWRP with a black themed Version and

%tw_version% is returning 3.6.0-11-0 and not 3.6.0-11-1 .

Thanks.
[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] BillGoss:
And there's your problem! TWRP doesn't support A12 encryption yet.
[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] Wishmasterflo:
@acuicultor did you had time to build a black TWRP theme for this?

Right now am still hardcoding this wonderful nice looking black Theme into the latest TWRP Version but of course it will be much easier to just have to apply the black theme to the latest TWRP Version.

Thanks.

P.S. I also fixed one bug I found when using the black theme. The decryption page was not showing the line and signs when entering the pssword since it was using the same color (black) as the background.

EDIT: I have created a Thread for the black themed TWRP here now! :)

[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] The Apostle:
Couple of questions... I just moved from an OP6 the OP8T. When I picked up the device I updated to 11.011.11 and then rooted.

With every device there's obvious update differences. Here are my questions.

1. Am I reading correctly that Kebab TWRP will not install a system/rom? Meaning, I can't just nandroid, wipe data, install new OOS, reinstall TWRP, reboot to TWRP, reinstall Magisk, reboot system.?

2. If so, I also read that updating through Magisk, I need to UNFREEZE all my frozen system garbage like Gmail, assistant, etc. Seems silly, but???
[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] BillGoss:
Lol!

I have no idea what you've been reading, but I'd say both points are incorrect.

Read the OP posts (plural) in this thread.

Read my https://xdaforums.com/t/guide-rooting-oos-with-twrp.4327417/ especially the links on keeping root in the in the second paragraph.

And read my https://xdaforums.com/t/guide-oneplus-8t-why-is-it-so.4380349/ for background info.

PS: you can even use TWRP to install incremental updates with a bit of extra work, but that's another story.
[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] Wishmasterflo:
Thanks. That is great. Do you have a XDA thread for that?

Then I can link your thread in the one I made for the full themed TWRP.

[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] theincognito:
It is based on 3.6.0-11-1, but the whole value after 11 (11-0, 11-1, 11-2) are only there to differentiate between newer and older 3.6.0-11 official builds. As far as the source is concerned, it will always be at 3.6.0-11, unless there is a major source update. And if we do get a source update, only the "3.6.0" will change. And if we get an Android version support upgrade, the "-11" will change to whatever android version that TWRP is currently supporting. Hope that's clear!
[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] theincognito:
Android 12 still isn't supported well for decryption (even without a pass/pin/pattern). I know the general TWRP changelog says that it works without any pass/pin/pattern, but it's only working for some devices and OnePlus 8T isn't one of them.

I just love having TWRP on my phone!

Here's an example of why I like it so much.

After updating from 11.0.11.11 to 11.0.12.12 I knew that I shouldn't boot my phone on the wrong slot.

But then I accidentally changed slots and rebooted. Crash Dump!

Now, I know how to get out of it: Power+Vol Up

But then I'd boot back into bootloader and use my PC to swap slots and reboot.

But I didn't have my PC with me!

TWRP to the rescue!

After Power+Vol Up reboots my phone I hold down Vol Dn and I end up in TWRP. Change slots, reboot system.

Tada! I'm back in business.

With TWRP I can do everything on my phone from backups, restores, installs, upgrades, downgrades, and rooting.

The only time I really need a PC is when:

- I forget to keep TWRP installed :(

- I have to format the data partition and restore my files
[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] Dior DNA:
I also love TWRP (for taking backups), but, for fixing mistakes, adb and fastboot(d) are sufficient (and sometimes necessary).

[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] Qnorsten:
It can not decrypt/read your data partition for some reason.

Hi!

Do you see the files when connecting the phone to your Computer?

Do you se files on one of these directories when checking from TWRP on the phone?

/sdcard/ or /data/media ?
[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] BillGoss:
Please read the forum rules in https://xdaforums.com/t/xda-developers-forum-rules.4200559/, especially "4. Use the English language".

When you format data you lose everything you've saved on the phone. After formatting data you must boot the phone so that it rebuilds /data and sets up internal storage (/sdcard).

You will then be able to copy files from your PC back to the phone.

If you didn't backup your phone files to a PC or USB storage device before formatting, then you've lost all of them.
[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] Ivanherrero:

Quick question. I just updated to an A12 custom ROM and transferred all my data back to my device but when I boot into twrp I don't see any data at all. Shows 0 mb of data. This isn't normal right? I am on the leatest release of twrp as well.
[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] BillGoss:
Twrp can't handle A12 encryption. Try removing the lockscreen password and then try TWRP again. It might work.
[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] gforceriders:
Forgot to mention I tested removing the lockscreen password and yet still showing no data. I will test again to verify the fact.
[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] BillGoss:

[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] BillGoss:
I looked up my tests on A12 and I need to clarify what my findings were:

- when I installed Pixel Extended A12, TWRP couldn't see /data.

- when I installed DerpFest 12 I had no issues with TWRP accessing /data.

So, I guess it's build-dependent.
[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] gforceriders:
Yes, you are correct. I'm testing a build for a dev and it's encrypted and Derp is not encrypted. That is the issue.

[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] BillGoss:
If you install a rom, you must also install the TWRP installer or you'll lose TWRP after rebooting.

Custom ROMs and OOS include a recovery image. That's why you need to install the TWRP installer to overwrite the rom's recovery.

Thanks for release , and keeping updated.

[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] BillGoss:
Unless they specifically have the ability to choose reboot targets (system, recovery, bootloader), then the answer is No as they'll reboot system (just like Magisk does).

You can either enable Settings>System>Developer options>Advanced reboot in OOS, or use a terminal command.

I use Termux as my terminal and it has a widget capability. I've set my widget up as shown in the top RHS of the screenshot.

TWRP instruction: "

A couple of questions if you don't mind.

So I've unlocked my bootloader, rooted, Oxygen OS currently updated to the newest stable build. And now I've installed TWRP using magisk.

Been out of the rooting game for a minute. Probably since nexus 4.

Is it worth going to a custom ROM + gapps?

And would I use TWRP to create a backup .zip file?

If I have to format data before flash. Wouldn't I lose my .zip backup?

I use to use titanium back in the day. So I'm just curious how the new school works. Lol.
[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] BillGoss:
Titanium Backup is an application backup solution. TWRP is a system backup solution.

TWRP doesn't produce zip files.

If you format data you lose everything stored on the phone. So you will need to backup to an external device (PC, USB) all your backups and installation files and ... everything on your internal storage that you want to keep.

TWRP let's you sideload installation zips (you use adb sideload <file name> so they don't have to be on the phone itself.

Hello

I noticed you had great experience with TWRP.

I just installed it in version 3.6 on my device.

I then made a full backup under TWRP of all the proposed settings.

Can you help me to configure the safest way TWRP to do a "Nandroid Backup" and also certain parameters to perform a restore if necessary?

Awaiting your information and help,

Hello

I used TWRP a lot on old LG or Samsung devices to make "Nandroid" backups before loading Custom LineageOS Roms and possibly restoring a previous installation in case of problems.

Today, I don't really know what I should keep as partitions that have become "dynamic" since OOS for the OnePlus 8 series.

Could you help me to tell me precisely the partitions to check for the backup and the identical restoration of my device, without data loss?

Is it necessary or useful to check all partitions (which I did on old devices) or only some?

Are there partitions that should not be ticked (see attached screenshots)?

Finally, do you always have to do a “Wipe>Factory Reset” before restoring the backup?

Thank you in advance for your information and advice.

Indeed, you are right: I have formulated several times, in different ways, with different words, different questions, which relate to backup and restore with TWRP.

If I asked these multiple questions, it is simply because I did not have an answer, precise, clear, limpid, understandable, easy to understand and to carry out….

Hello

Back to your question:

Have you done an OTA update of your device, changed the version of OOS (from OOS 10 to OOS 11, for example?)

1°) is your device rooted?

2°) if so, I suggest you follow this tutorial which will guide you step by step with OOS updates, with TWRP and Magisk: https://www.thecustomdroid.com/install-ota-update-rooted -android-device-guide/#comment-27709 and follow step 4 for TWRP

3°) if your device is not rooted, the easiest way would probably be to reinstall TWRP in A and B with your device in "boot loader" and the "ADB" commands...

Note that I read a tutorial that should allow you to keep the TWRP: https://www.droidwin.com/permanentl...ration-hash=25ecde9ffc433438c96b5e112017434a# comment-4122 but I never found the commands provided in step #5 of this tutorial.

Please let me know if you achieved what you want to do to keep TWRP and how you achieved it!!

cordially
