Hi,

I am on stock OOS (11.0.11.11) and have been reading through the posts and have a question. I had a Oneplus 7 Pro before the 8T and have a question re unlocking bootloader, flashing TWRP via Fastboot and using Magisk to root the phone. Question,
1 Following unlocking the bootloader can I just flash TWRP temporarily via fastboot then reboot recovery sideload TWRP installer and flash that in TWRP. This would give me TWRP on both A & B Slots is this correct? If I then download or Sideload Magisk and flash that via TWRP will that not root my phone albeit in OOS 11?
I've read a lot on this thread and it seems to be over complicating the process, unless there is something I am missing that is peculiar to the 8T,
I would be grateful if someone could let me know. TIA

Hi Bill Goss thanks for your reply, it's basically saying what I said In My post apart from one bit that I dont quite believe it say to flash TWRP installer after flashing Magisk. If you do that you unroot your phone 😂😂
That's not true. Flashing the TWRP installer simply flashes TWRP to both slots. Having TWRP installed has no impact at all on root.

Hi!
I took this one, but I guess the one you posted might be the same.
Tnx. It is mor than 3 timed bigger...

I tried both. And looks similar in the output.

BUT my 8T is on B and when I switch to A after copy, device shows unlocked screen, then gets dark and after a while "Qualcom crash dump" screen.

When I boot to twrp, when I am on slot B /data looks normal. On A /data is 0!?

Switching back to B, it boots as normal...

Any hint?

I would check that A and B are all the same by comparing the md5sum of the *_a and *_b partitions in /dev/block/by-name

Run md5sum /dev/block/by-name/*_[ab] in a terminal (you'll need root). Or run it in the TWRP Terminal.
Ah. Great tnx!

Found these differences:

c4bb50fd2624f252bc74647c3d8e48b6 /dev/block/by-name/boot_a 6ecb19aa87e733382e505ccb9b8863e4 /dev/block/by-name/boot_b 268beb8c789265fa81b160a120c7979c /dev/block/by-name/dtbo_a 881f5358d9c2a0215876c68356818173 /dev/block/by-name/dtbo_b 5a9d1dabf734a4acf14d8cb4348d2425 /dev/block/by-name/vbmeta_a 0b8e2946263992819ebf4e78fed8a397 /dev/block/by-name/vbmeta_b

Active slote is B. All others are identical.

What does it mean now?
Do really all have to be identical?
If so, what do I have to do to get it identical again (because copy-partitions-20210323_1922.zip did not sync these)!?

Tnx for your great support!

That means that the rom you installed included those three system partitions files and that the copy-partitions did it's work properly (if you look at the shell script it runs it has some partitions excluded).
If you want to be able to boot either slot, then you'll have to manually sync those three partitions.
I created my own shell script (attached, needs root) because I wanted to be able to sync all partitions and to be able to specify just one.

Hi!!!

new with 8T today I have questions


Is not the first time I use TWRP. My last phone dead yesterday. It had 3 years and I did last root method....3 years ago with TWRP, flashing supersu, etc etc


Now, reading how to root this mobile I read 2 different methods

  1. One is with fastboot and images (this one: https://forum.xda-developers.com/t/guide-oneplus-8t-easy-root-for-all-unlocked-variants.4210775/)

  2. Other is with TWRP

is it better to flash TWRP and flash with it Magisk? or is similar to do it with mobile connected to PC and writting codes in console?


I think, but I am not sure, that, is better to have TWRP if I want to install later other Custom ROMs, but I want to have strong idea why is better TWRP than other method.

Thank you

    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

    @theincognito all these changes from TWRP_3.6.0_11-2-kebab are the ones already included in your last Update or?

    View attachment 5498331

    4 & 5 are new. There is one more build coming soon with a change (3.6.0_11-3-kebab). I will update my OP then.

    @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.
    I made an ui theme zip which can be used for theming any twrp with theme support

    Introduction:

    Team Win Recovery Project or TWRP for short, is a custom recovery built with ease of use and customization in mind. We started from the ground up by taking AOSP recovery and loading it with the standard recovery options, then added a lot of our own features. It's a fully touch driven user interface , no more volume rocker or power buttons to mash. The GUI is also fully XML driven and completely theme-able. You can change just about every aspect of the look and feel.

    Key Features:

    Touchscreen driven with real buttons and drag-to-scroll
    XML-based GUI that allows full customization of the layout true theming!
    Settings are saved to the sdcard and persist through reboots
    Ability to choose which partitions to back up and which to restore
    Ability to choose to compress backups now with pigz (multi-core processor support for faster compression times)
    Onscreen keyboard
    Easy selection of internal/external storage

    In addition to the above new features, TWRP features a scripting engine that allows an app to send commands to the recovery for the recovery to perform during startup. We call this scripting engine OpenRecoveryScript. This engine will be put to use immediately in the GooManager app. GooManager will be able to install recoveries automatically for most supported devices. The app will also let you choose to install multiple zips from within Android, wipe, and run a backup.

    We are looking for other talented developers, themers, and device maintainers if they are interested in helping with a free, open source project.

    Source Code:

    GitHub - https://github.com/TeamWin/android_bootable_recovery

    Gerrit Instance - http://gerrit.twrp.me

    If you have made your own TWRP build for an unsupported device, please let us know. We might add your build to the list of unofficial builds. Bear in mind that we are working hard to add more devices and we may add your device to our official build list later.


    Hello, this is TWRP, for Oneplus 8T

    Installation:
    # To temporarily boot it
    fastboot boot <twrp_file_name>.img

    # Since 8T/9R has a separate recovery partition, you can flash the recovery with
    fastboot flash recovery <twrp_file_name>.img

    Updating to a newer build:
    Simply flash the latest TWRP installer zip from TWRP

    OR

    Flash the img from TWRP/fastboot


    FAQ/Know Bugs are given in post #2

    @Lossyx
    @osm0sis
    @Nebrassy
    @Qnorsten

    for helping in making this recovery. Without these people, TWRP for this device would not have been possible. :D

    FAQ and Known bugs of TWRP:

    • If you are planning to switch to a custom ROM, and are currently on OOS/H2OS, format /data, switch slot, reboot to TWRP and then sideload/flash the ROM + installer.
    • It's better to flash ROM + TWRP installer, if you want to keep your TWRP after flashing a ROM.
    • Don't format /data, after a flashing a ROM, before the first reboot.
    • It takes around 50s to actually boot into TWRP.

    Ideal way to flash:
    • For OOS to Custom ROM - Format /data, switch slot, reboot to TWRP, sideload/flash ROM + installer, reboot to TWRP, flash Magisk/Gapps. Reboot to system.
    • For Custom to Custom ROM - Format /data. Flash ROM + installer, reboot to TWRP, flash Magisk/Gapps. Reboot to system.
    • For updating a custom ROM - Flash ROM + installer, reboot to TWRP, flash Magisk/Gapps. Reboot to system
    • For custom ROM to OOS - Format /data. Flash ROM + installer, reboot to TWRP, flash Magisk. Reboot to system.

    PS: After formatting /data, until the first time the device is booted to system, the files you send to phone via MTP (USB) will be at /data/media, not at /sdcard

    PS2: If, for some reason, you cannot send files to phone after formatting /data and rebooting to TWRP, press vol +, vol - and power button simultaneously.

    PS3: Factory reset WILL NOT wipe internal storage.

    Steps for backing up and restoring data in TWRP (Huge thanks to @BillGoss )

    TL;DR for data backup on custom ROMs:

    1. Backup /data (copy the backup folder to PC if you will format /data).
    2. Flash the ROM and boot it once to system.
    3. Restore /data (copy the backup folder back from PC if you formatted in step 1) and boot into system.
    4. If you find any issues like missing navigation bar or blank screen or something, just do a normal reboot again to system.

    System Backup and Restore
    The "system" partitions on the OnePlus 8T are:
    • Boot
    • DTBO
    • Super which contains the logical system, system_ext, odm, product, and vendor partitions
    Just backup and restore these partitions.
    Do NOT backup/restore any of the logical partitions individually.


    Data Backup
    1. Make sure USB debugging is enabled
    2. You do NOT need to remove your password

    In TWRP
    1. Backup: Select only the Data partition.
    2. Reboot System

    Restore
    Remove the current password before starting the restore process by Settings>Security & Lock Screen>Screen lock: Select Swipe (if prompted tap on "Yes, remove")
    If you don't do this, the system will not reboot properly after restoring.

    This will also remove your fingerprint data and your lockscreen (encryption) password (you won't be prompted for a password in TWRP or when you restart the system)

    In TWRP
    1. Wipe>Factory Reset
    2. Reboot System (this will rebuild the data partition)

    Back in TWRP
    1. Restore: Select the backup you want to restore
    2. Remove the SIM card. If you don't do this the system won't boot properly.
    3. Reboot system, making sure the phone is not connected to a PC

    Notes:
    1. At this point the phone will take longer than usual to boot - that's normal
    2. You will be presented with a blank screen
      • Connect the phone to a PC. You should be able to see the phone using adb devices
      • Disconnect the phone from the PC
    3. Hold the Power button down and select Restart

    In System
    1. Settings>Security & Lock Screen>Screen lock: set your password
    2. Insert the SIM card
    Note: Your fingerprints will have been restored because the backup was taken with the password set.
