TWRP and Root for Android 8.0 Oreo

[dreams.sri]

I flashed the latest Open Beta 25 yesterday and it took me some time to figure out how to properly root that. I was searching for a compatible TWRP for Android Oreo and I stumbled upon one when I was reading through pages and pages of comments from our community.

So, I am writing the steps here with the necessary files so that everyone can find it in one place.

This is not my work. All credits go to the original developers. I am just consolidating the steps I followed here. If I am violating any rules, please feel free to close this thread.

Steps to install TWRP and Root:

Note: My phone was encrypted when I tried this.

1. Copy the downloaded SuperSU Zip file to your phone.
2. Copy the TWRP file to the folder where ADB and Fastboot are installed.
3. Turn off your OnePlus 3/3T. Boot your OnePlus 3/3T into Fasboot mode > Press and hold the Volume Up Button + Power Button.
4. Connect your phone to your PC via USB Cable.
5. Open a command window on the folder where ADB and Fastboot are installed. Go to the folder where ADB and Fastboot are installed. Hold down Shift Key > Right Click on the empty space > Choose ‘Open CMD Here’.
6. Execute the below command in the command window to see if your device is properly connected:

fastboot devices

7. Make sure the TWRP file is in the ADB folder. Execute the below command to install TWRP on your OnePlus 3/3T running Android Oreo:

fastboot flash recovery TWRP-Oreo-OnePlus-3-3T.img

Do not restart your device upon installation. The procedure is not yet over.
8. Assuming you are now in Fastboot Mode, use the volume buttons and choose ‘Recovery Mode’ and then press the power button to enter TWRP Recovery.
9. Once you are in TWRP > Tap on ‘Install’ > Choose the SuperSU Zip file which you have downloaded from above > Swipe right to flash.
10. Reboot your device.

If you have other TWRP already installed, any reason not just to install the compatible one by flashing image of compatible one using that?

We should be able to install twrp without connecting to pc if we already have twrp

You could do that. Shouldn't be an issue, I guess. The above steps are just what I followed.

Yes, but isn't Oreo package replacing TWRP with OnePlus recovery?

Install the recovery img in TWRP again after the zip. Reboot to recovery to confirm it didn't overwrite TWRP

No, what he says is that, once you install the Oreo Update Zip from TWRP it will be replaced with TWRP. I guess we could avoid this by immediately flashing the TWRP Zip soon after flashing the Oreo Zip.

He means stock Oreo zip. If you flash OnePlus stock rom in TWRP and don't reflash TWRP stock zip replaces it with OnePlus recovery

Got error 7 while trying to install official Oreo beta from TWRP. Maybe a recovery issue not sure. I needed to flash last N beta and update from settings to Oreo beta

 

[articblaster7]

Its only possible with oneplus recovery. Trust me.

 

[gmlogan]

Its only possible with oneplus recovery. Trust me.

OK, but after you have flashed Orea Beat with their recovery will it run OK with Twrp for backups and rooting etc

 

[articblaster7]

I dont have time to test right now. But i'm sure to Will vê possible now or in a near future

You could download the Stock Oxygen OS Recovery and fastboot flash the recovery > Go to Stock Recovery > Go to 'Install from ADB' > Connect phone to PC > Sideload the update Zip > Boot into OREO > Reboot to Fastboot > Flash TWRP > Flash SuperSU. Will hardly take 15 mins.

True that, agreed!:good:

True that, agreed!:good:

1) Flash oreo compatible recovery
2) Flash Rom
3) Flash TWRP recovery
4)Flash root
