When i first opened the wallet I swear i saw a button under advanced settings that said switch mode to cold wallet or something.. but now I can't find it... I tried reinstalling, and everthing, still no success... anyone know if this is a bug with Bither or something I do wrong??
It's not under "Advanced Settings"... it was just under the standard settings when you click the little "gear" icon. Perhaps try and delete the app data and then restart it and see if it gives you the option again.

And, I don't think you need to be offline to see the option... as it shows up fine on mine when connected to 4G. As per the popup, it just needs to be offline to be able to use it as "Bither Cold":

Sorry for the late. Because our team members are in China, and you know the GFW, we does not check bitcointalk forum often. This account is Bitpie Wallet, which is also from Bither Team.
As HCP said, you need to shut off your internet connection/ flight mode to set the cold mode of your Bither. Once you set it into a cold wallet, you cannot return to the hot mode any more.
We just release a new version v1.8.6, and it has tuning the performance of importing private keys and reload transaction data.
Another advice: Bitpie Wallet (bitpie.com) is a multi-chain wallet developed by us following bither, which is easier to use, so we strongly recommend you to use Bitpie instead of Bither.
