I tried following the instructions for OnePlus 3, using the latest files at :

Recovery would install OK but I couldn’t boot into it.
Using TWRP recovery both direct install from internal storage or ADB sideload failed.
In the end I was able to install 2-2.0 after installing and booting into eOS 1.21 recovery (filename is https://images.ecloud.global/dev/oneplus3/recovery-e-1.21-r-20240323388943-dev-oneplus3.img), then using “Apply update” from e-1.21 recovery.
