Hey, quick question. To update this TWRP, when the OP says flash the twrp-installer.zip, that means flash the zip in TWRP, then reboot to recovery into said updated TWRP, correct? Just wanna be 100% sure, since this is my first A/B device (been using a OP5 since it was released and only JUST switched to a OP9). If I'm just updating TWRP, I don't need to flash to any specific slot, right? Since there's other ways to flash ZIPs, it seemed like a prudent question . . at least in my case.
Thanks you for this TWRP! It always nice to have a backup(s) of all of my partitions on my backup SSD, just in case my device decides to have a bad time! So thank you for your contributions to the community!
