Hallo, I’m also new in the communitiy. Some weeks ago I bought a Pixel 6 with Android 16. The downgrade to android 15 is failed, the zip from google android was out of function. But I thought, the risk of bricking the device is lowly, because the difference between android 15 and 16 is also not high.
I tried it with android 16 and it was successful, the device runs good with oriole.
