The main problem is that most users dont have oem unlock after oreo update (e.g me)

Flash this official firmware through Odin if you have Exynos S8, and you'll get OEM unlock option.

I also manually updated to Oreo through this firmware and not through OTA. Also, note that flashing this will not wipe any of your existing data and also will not trip your knox

Flashed official XEO for Poland and still OEM unlock isnt there :/

Does the Oreo update affect the the locked bootloader on the Snapdragon version? I thought it was impossible to install TWRP on the Snapdragon versions of the S8?

Try use AQK7 ( 4 file firmware + re-partition PIT)

In my case I 100% success returned form CRAP to AQK7.
OEM unlock is in dev settings, no RMM and FRP.

Powodzenia ^_^

I'm guessing this is not for the US snapdragon variant.

iamnotexisting · Feb 20, 2018

There's no way this can work on US Snapdragon, we don't have a OEM unlock option here.

Silenus21 · Feb 21, 2018

Tired of the US locked bootloaders.
Next time I'll get a Exynos GS9 for sure.

Haha yes! Exynos devices are best in performance and battery too.

TWRP trips Knox if I'm not mistaken.

i did this guide and everything is went good but when i restarted the phone it went to a softbrick and i had to do a restore...
the error was something on the original binary

juan_itoo · Feb 27, 2018

to have the OEM option, will I have to go back to crap?

potsykate · Feb 28, 2018

I have just tried this method and booted into TWRP but the screen was totally unresponsive, rebooted and still the same. I had to go back to Oreo.

How do I get around this problem?
