Hello guys a noob question actually, how do I flash the firmware, means do I have to backup everything before flashing, or I can just simply flash it.
Any help is greatly appreciated.
Thank you guys.
Simply flash it from within TWRP. No data will get lost.
But be sure to pick the right version, as there is a one for OP3 and one for OP3T!

Thanks man i also saw beta versions too, so which one should i flash stable or beta version
Stable of course!
9.0.6 is the latest version.

Edit: I have to correct myself: Depending on what firmware version that is running on your op3(t) right now, of course you might lose data!

So let me ask first: Which version do you have installed right now?

    Flashable Firmware+Modem ZIPs by hellcat50

    This flashable zip will update or downgrade your Firmware and Modem Files of your OnePlus 3 or 3T.

    If you encounter any errors during the installation process, feel free to report it to me.
    Normally I test all the .zip files before I upload them, so everything should work fine.

    Current stable firmware version: OP3T: 9.0.6 | OP3: 9.0.6



    Note: You will lose your data if you are coming from 5.0.x firmware and your storage is encrypted! If you want to upgrade from 5.0.x to 9.0.x firmware and update the ROM and don't want to clean flash, you can follow this guide in order to keep your data (only applies if your data is encrypted) (thanks to @nvertigo67):
