Change the ROM on my phone

Hi,

sry if this has been asked before, but I havn't found a answer to this.
I want to change the rom on my phone (from CM11 to Beanstalk) with a full wipe (erases everything on the phone).
Do I have to upload my game data, or can I just flash the new ROM, download the game again and everything is the same as before?

best regards

I have switched roms before and not lost my account. It always makes me nervous though. If you have another device, I would recommend setting up the account transfer (the old and long one) to make a transfer. Then if for some reason you lose your account, it will transfer there in a couple days weeks months? the time is definitely different every time.

Basically this is just a complete safeguard. Its 99.9% chance of not losing your account, but just in case something goes wrong (or you brick your phone completely) you can still get your account back when the transfer is complete.
Since it probably wont be an issue, just continue playing on your new ROM as usual. when you turn on your game and see your account is gone, get your other device and start the new (instant) transfer to be back in business

you could always use Titanium Backup to backup the app + data and then restore after you install the ROM, just to be on the safe side. but no you shouldnt lose your account from changing ROMS
