OnePlus 6T | How to install TWRP and root with Magisk | May 2019

Ever since Android Nougat was released, Google recommended some changes to boot partition that will make software updates seamless, i.e, some tasks performed during software updates are now performed in the background so the software updates don't take as long as they used to. However, this means that developers will have to tackle an extra hurdle and it makes their life hard.

That's exactly what happened to TWRP. Previously, all you needed to install TWRP was the image file and execute fastboot command. But now, you need to flash an installer zip to install TWRP permanently. But as always, someone made a workaround for that, too. This workaround is implemented since TWRP 3.3.0-0. That means, we no longer have to download an additional installer zip to install TWRP permanently.

And now that a new method of installation has been found, TWRP team has decided to trash the installer zip method and will no longer provide an installer zip from the next version of TWRP 3.3.0-0. They were considerate enough to provide a zip for TWRP 3.3.0-0 for people to make a smooth transition.

In this video, since I used TWRP 3.3.0-0, I covered both the methods. So if you are installing versions lower than 3.3.0-0, you must follow the installer zip method and if you're installing versions higher than 3.3.0-0, you must follow the new method.

how is magisk updated every time an update comes out on the oneplus 6t and with recovery twrp?

[adomasromanovas]

long time no needed to install twrp (but not new with it). used your guide and got stuck after "fastboot boot twrp.img". i see 1+ logo and "fastboot mode". and noting happens. twrp is not leading up. used different twrp "twrp-3.3.1-1-fajita.img" and "twrp-3.2.3-2-fajita.img"
still can't boot to twrp.
have any suggestions?
