Well, the project has announced that 12.0 is discontinued, and that 12.1 will take some time to get ready. All phones are therefore marked as discontinued at the moment.
I did the usual way of flashing this new update via TWRP boot and ADB sideloading it. I only wipe Dalvic Cache and System, and kept the Data partition.
I booted the newest TWRP image from fastboot, then sideloaded 12.1 with only wipe of system, dalvik, but not data. Worked fine. I guess sideloading from other recoveries will yield the same result.
Twrp can't decrypt data on android 12. You need have otg or sideload the file.
