i am having so many different issues with flashing twrp then roms. After reading, i understand that "Failed to mount " errors are normal but after finishing the flashing process I am stuck on boot. One time it got past it and was able to boot, but then gapps would not flash nor magisk and it still said unable to mount storage.

Have a look at the rather lengthy conversation I had with @iooxda starting https://forum.xda-developers.com/t/...ect-8t-kebab-2021-09-04.4302449/post-85376567
It may help you understand what's going on.
I've found that I could successfully flash Los with Gapps pico (so you don't run into "insufficient space" problems) and Magisk.
If you're starting from a working OOS install, then I strongly suggest you flash the copy-partition.zip mentioned in the conversation as this avoids issues when switching slots.

Hello!

I am just trying to undersand at which step of the flashing instructions the "copy-partitions.zip" should be flashed.
Is it the first step you do to flash the copy-partitions before switching slot and reboot to TWRP (so I guess those steps can be skipped when havening flashed the copy-partitons or?)

Also regarding the "format data" it seems there are different informations on when that should be done.
In the OP it is the first step when coming from OOS to custom ROM but in the post you posted here it is mentioned like "do the format after flashing and rebooting to TWRP" .
So I wonder which step is the correct one to do the format data and flash the copy-partitons from flashing from OOS to custom ROM.

I thought like this perhaps?
But I guess the format data should be after point 6. or, and is it so that 3. and 4. can be skipped when flashing the copy-partitons ?

1. Format data
2. Flash copy_partitions.zip
3. switch slot
4. reboot to TWRP
5. sideload/flash ROM and TWRP Installer zip
6. reboot to TWRP
7. Flash Magisk
8. Flash Gapps
9. Reboot to System


Thanks a lot.

thank you for sharing this. I got it to work but this is by far the oddest experience i have had rooting/flashing a phone. I want to install nethunter now but I am worried how that will go lol.

Strange. What if you reflash TWRP once again and then try again to flash Magisk?
Just tried that. Flashed TWRP again from my MacBook this time. Still same result and nothing is happening.

I even tried removing my screen lock but that didn't make a difference

I've attached screen shots from TWRP during the installation. No errors

Things to know about A/B devices:
1. The slots have different versions of firmware/software because an update only updates one of the slots. This means that it's very likely that your system won't boot if you just change slots.
2. When you install an update or a new rom, the changes are always made to the inactive slot.

So, if you're currently on OOS and install a custom rom, then it gets installed to the inactive slot which has firmware/software belonging to the previous version of OOS, which is not what you want.

There are two ways to avoid this problem of installing the new rom on outdated firmware/software:
1. Sync the inactive slot to be identical to the current working slot before starting the installation. Copy-partitions.zip does this.
2. Boot to the inactive slot and then install new new rom. This way the rom gets installed on the slot that has the latest version of the firmware/software.

The OP uses the 2nd method, but I prefer the first. In fact, I sync my active slot to the inactive one after every OOS update once I know all is good and I'm not going to revert to the previous version.
Side note: if you've synced the slots then your system will successfully boot on either slot!

As to the order of "format then flash" or "flash then format", both achieve the same result. But I prefer to do everything on my phone without using a PC (where possible) or OTG. Since all the installation files on the phone will be gone after a format, I prefer to do the installs first and then do the format.
The fact that currently (version 210904 of TWRP) the data partition isn't set up properly after a format until after the system is rebooted, also means you can't push files to the phone before the system reboot and must use sideloading if installing stuff. Hence my strong preference for "flash then format" at this point.

Great. That explained everything I wanted to know about this to me now. Thanks a lot. :cowboy:

Hi, just to clarify. I'm on stock OOS with Magisk (stock recovery) and just got the notification about the new update. Does this mean, that if I flash this recovery I still would not be able to update the system with OxygenUpdater?
You can't flash OOS in TWRP.

If you're update is a full rom (~2+ GB) then you can install it through system update even if you're rooted and/or have TWRP installed.

Hello. I guess that is already being worked for TWRP but I dont think it is ready yet so as far as I know there is no recovery yet which can decrypt Data on Android 12 but that will surly come in the not so far away future. Lets see.
Also I read that when you want to flash a Android 12 ROM in TWRP there is an adjust in the metadata of the file needed to have the phone name like Oneplus8t instead of Kebab in the name in order for TWRP to flash it.
And the process of entering recovery is different when on Android 12.

Android 12 enter recovery mode
- When the phone is running, during a normal reboot just hold the VOL+ button
- When the phone is turned off, hold VOL+ and POWER, when the Oneplus logo appears, release the POWER button

    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

    @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.
