Hi, I updated today to Android 10 and I would like to know (just in case I need to downgrade back to Android 9) which version should I download from the three that appear here: https://www.asus.com/Phone/ROG-Phone-II/HelpDesk_BIOS/ in case I wanna downgrade. The three options are:
Version CN-17.0225.2001.13 [1]
Version Android 10 downgrade to P (CN) [2]
Version Android 10 downgrade to P (WW) [3]
Now, the version of my phone is:

Which version is the one for me? I this it's option [3] for the WW but I'm not entirely sure.
