TWRP and Root for Android 8.0 Oreo

[candiesdoodle]

Does this work for oneplus3t? I do need a different bootloader then I suppose?

You will need a different bootloader. Pls.seatch .. you should be able to find it
Overall process remains same.

Thanks Brother for the post.

Updated to Oreo. Everything works good and no issues so far.

Already in Place:
Android 7.1.2
TWRP 3.1.1.2
SuperSU v2.82-201705271822

Steps Followed:
Took all backup(Titanium)
Booted to Recovery
Updated TWRP to the TWRP-Oreo-Oneplus-3-3T(Link available in the thread post.)
Flashed SuperSu-v2.82-SR5-20171001224502(Link available in the thread post.)
Cleared Cache and Dalvik

Flashed Oxygen OS Open Beta 25(Did not boot to system after that)
Just as a precaution - Flashed Recovery and SuperSU again.

Reboot, Voilà

Guys small clarification does the new TWRP become the default term for flashing both oreo and Naugat or do we keep the old TWRP handy for returning back to Naugat?

 

[rintomr]

Good Question, But not sure about the details.
From my experience, I updated the TWRP before flashing Oreo and rebooted to recovery(Did not reboot to System though) and it was working fine.

I could go back to Nougat and for to Oreo with the new TWRP, which was a good surprise.

Wrong time and date

Is it just for me that in TWRP the date is set to February 1971 and totally wrong time?

Diito! I think TWRP needs to be optimised for Oreo.

 

[null0seven]

1971. Time it's a little back.. Not that bad.

 

[Pachulongui]

Do you need to unlock the bootloader???

Do you need to unlock the bootloader???

Of course, yes.

I follow the instruction from the first post.
After booting the phone and trying to boot again to Recovery the oneplus recovery is installed again, i tried to flash TWRP 3 times and it always works if i immediately enter it, but as soon as i boot to android it will be deleted again.

Anyone knows a fix?

Did you flash twrp and supersu after rom? That always got me in the past.

 

[ach4825]

Stuck in recovery

I follwed the steps, but my phone is stuck in twrp welcome screen. I can't even install the supersu. please advice.

I had the same problem. Then i did everything again, but i used the official twrp from their website (i can´t paste a link here). After that you have to wait, it took 8min on me.

I did exactly in your sequence (Open Beta 26) and finally restarted the phone.

Its now stuck (?) on the bootlogo, black background with the oneplus-logo (powered by android)
Nothing happens, since 30 mins approximately.

I repeated the flash (could re-enter TWRP thank god) and end with the same result.
Any help appreciated !

 

[null0seven]

Restart the phone by Power button.
And SuperSU SR5 works.
Also backup of N (Android 7) and restore on O (Android 8) .., not so good.

I had the same problem if I didn't flash superSU right after flashing twrp .... So just try flashing both of them simultaneously without booting in the system even once and it will work fine

Can this twrp file use for Mate 9 - Mate 9 Pro? Any ideas?
