I got a notification for a new 11.02 version of rr.
This is fake. The updater app is searching for updates but as the update server does not know about a z2 pro the dev may patched the updater app to search for a different device.
With that app behaviour people first think this is an official rr build as update app is there and working.
Of course this fake is only good as long as there is no update for the fake device.
Once there is an update for the device that is patched into updater app you will get the update notification but of course you will not be able to download or install it.
Shame on the rr dev that he tries to pretend it is an official rr version for z2 Pro. That would be exactly the reason not to install this rom for me.
Who knows what kind of things have been faked and changed additionally in this rom. No thank you, I dont what this rom dear dev.
Hope this explanation helps a bit. I suggest to change to a different custom rom.
