[CLOSED] [No longer maintained] [RECOVERY] [11] [OFFICIAL] TeamWin Recovery Project (8T / Kebab) (2022-03-09)

[theincognito]

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

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

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.

Works flash in fkm?

 

[KrunkKracker]

This is great!

 

[wawanRedblack]

Works flash in fkm?

fastboot only

 

[Dhanush-raj]

Thanks for it!
Gonna try it!

 

[pratyush28]

Amazing! My OnePlus 8T is arriving tomorrow. Perfect timing for TWRP, thanks a lot for the detailed instructions as I am going to need it.

 

[tyler19820201]

I was flashing this twrp with the previous test_kebab twrp as flash .img. Choosing recovery partition and was thicking "install to both slots".
So far works good.

 

[apophis9283]

Bro, I'm happy for you. Great job.

 

[dpryor88]

@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!

 

[apophis9283]

He has this. Again, great job. Glad folks now have a thread to come to for proper support

Works flash in fkm?

Yep, works fine.

You can also flash the zip in the Magisk app, manually from the modules page.

Booted on 9R but unable to decrypt data, after switching to 9R compatible kernel everything is working fine.
Nice job bro.

Is there a unified kernel tree you know of?

I'm using kernel source from aospa.

@YumeMichi Thanks a lot for this. I shall make a build with the AOSPA kernel and test on 8T. Should I release it here then, or do you wanna release for 9R?

It would be great if you can do that.

 

[theincognito]

It would be great if you can do that.

I will PM you the build once it's done Then let me know whether it works for 9R too
