How to on recover mode on my device How to Enter Recovery Mode on Sony Xperia XZ2? I tried a few methods to do and the phone doesn't do anything no factory mode at all. Now what? How can I on recovery mode on my device?
It appears that the XZ2 does not come with the recovery mode. There's no stock recovery to boot to.

So, the key combinations won't work until you root your phone and flash a custom recovery (which might not exist yet either).

If your intention is to reset the device, then as mentioned in the source link below, you can do it from within the Android system or the Sony Companion.
