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.

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

FAQ and Known bugs of TWRP:

  • OOS/H2OS flashing is broken.
  • 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

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 )

Remove any password/pin/pattern before doing this

Backup

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

Restore
In TWRP
If you skip this step you will not be able to successfully start the system after restoring data
  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. Reboot system

    Note:
    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 or a toast message saying "com.android.phone keeps stopping."
      Tap "Close app", hold the Power button down to be presented with the option to (Lockdown), Power off, or Restart. Select Restart
    3. It may take a couple of restarts

If you want to backup and restore fingerprints too, follow the guide in the attached file

@theincognito Though I am a fastboot flash guy at this point (honestly forgot how to even use TWRP after all this time), I appreciate all the work and time you (and apop) put in for this project. It's definitely going to make this device appeal to more Android enthusiasts as most are used to and prefer TWRP for flashing I've noticed. And that will lead to more development (hopefully) for the device. That seems to have been the case with previous devices I've owned that had TWRP available, but also had the fastboot method available.

Anyway, I have been up for like 32 hours, so if what I've said doesn't make much sense, sorry.

Thanks @theincognito for all your work and time, and I hope this brings more to the 8t community. Good job!

    Hi all!

    If someone is intressted I created a black Themed TWRP Version (Themed by @acuicultor and @Morphine1) for the Oneplus 8t.
    This TWRP is the same one as the one here in the OP just with the black Theme applied to it.
    I put the IMG file for that here which can just be booted with fastboot boot twrp_black-3.5.2_11-0-kebab.img

    EDIT: I have uploaded the flashable .ZIP installer with black theme on the above link as well now.

    As of now I only put the black themed .IMG file there but will provide a black themed installer.zip as well later on.

    Wow. The UI looks nice. Really nice. Could you make a TWRP theme instead of hardcoding into the TWRP? If that's possible, you can create a thread of TWRP black theme. Then, I can release the normal one as usual and users (including me, I love black theme lol) can come to your thread and get the theme zip. This will also make it build independent. Really love your work. @acuicultor @Morphine1 @Wishmasterflo

    OTG is known broken I think, at least on a bunch of twrp-11 devices, not sure here

    Uhh, that sounds nasty.. Things were so much easier with the Nexus 5 and the OP5T..

    For a novice it is such a big effort nowadays to backup and try out new ROMs.

    I think I'll just stay with OOS then. However: thanks for your explanation!

    Blame Google for their virtual A/B partition system :D

    Thank you!

    Yes, I plan on installing Magisk. I know, this is not directly the topic of this thread but still related to my question:
    Lets say I installed TWRP and Magisk and there is an OTA available and I want to stay rooted: Do I need to flash the original boot.img before flashing the OTA or not? (And after the OTA I would reinstall Magisk in the manager app)

    Some guides do say to flash the original boot.img, some not. I don't understand in which cases this needs to be done?

    An OOS OTA incremental update checks for the presence of stock versions of both boot and recovery before it runs.
    This means that if you're using Magisk you have to restore the stock boot image before starting the update. And if you're using TWRP you have to restore the stock recovery image before starting the update.

    I think this is only true if you run the global version (and possible the T-Mobile version) where they only provide incremental zips over OTA. It has been a while since I used the stock system update (mostly use oxygen updater to download my OTA). At least for my phone running EU rom the system update will show a prompt like "root detected download full OTA zip" and then it will update normally.
    After install before reboot , I just flash the TWRP retention module in magisk manager and then onstall magisk to inactive slot from magisk manager. No need go restore any stock boot or recovery.
