i have found a way to unlock all the teams atleast and it will stay forever and you'll be able to login to google play account too so it will stay even in the original app without any modding, but its a bit time consuming if you want to do multiple teams and also there is no way to save the unlimited money and skips and med kits and energy drinks
the way requires a rooted android or any android emulator on pc like mumuplayer and luckypatcher, if you keep playing on that device then you can play with everything unlimited, but if you want to transfer to you google play account and play original app with updates then you can only unlock the teams and currency will not transfer, i think they did this intentionally so people using this way won't have unlimited stuff on their actual account
