This will probably be locked/deleted, (and I get it!), but then again what's the difference to someone
posting/replying about 'rooting' sites and for new O.S.'s, that let you do what you want

(Although this has nothing to do with 'rooting')
For a start, (sort of like 'iTunes' software for Apple), the BEST BY FAR PC, (Mac??) software for your
Android devices is 'Wondershare'. If you have a cracked version of that, then good for you, but I am
'not' going to help anyone, in that regard. Except to say that while using it.............
Download anything you want from Google-Play. No matter the cost. Back it up using Wondershare.
Now you have something like 20/30/40 mins? to decide that, "Oohh, that's not what I wanted", and
select from within Google-Play to Delete & Refund !! Then manually re-install from Wondershare.
If it's something I really want though, And it costs say $1.99 or $3.99, then I DO, regularly buy it !
But if they are charging say $30 - $100 etc, and want to 'play' with it for fun, for no commercial
interest, then I will just 'play' with it !
