Flashed custom rom and phone still boots to OOS

[biron_w]

I flashed LiquidRemix but when I went to reboot into TWRP to flash gapps and magisk my phone just booted straight to OOS.
So I tried again but instead of rebooting to TWRP I just went to boot up and again my phone booted to OOS.
I only did a factory reset first time. Second time I wiped system as well but ended up with no OS so had to use fastboot to get OOS back on my phone.
I've tried switching slots in TWRP but it makes no difference. I always boot to OOS.
I'm guessing it's something to do with the a/b partitions but I've no idea what's happening.
I'm on the latest stable OOS Pie build.

You have to boot into trwp first then flash the latest Official Stable OOS Pie then reboot trwp then flash it again. If you don't do that (flash it twice in twrp) you'll end up having the issue you're having. It happened to me too until someone posted the correct flash procedure in another thread. The devs rarely update the flash instructions in their OP's.

I'll try that. Cheers.

It worked! Nice one.
