Yep, it's back to basics. I would get rid of the puppy pads and just put him outside when he needs to go. The trouble with puppy pads or newspaper is, you are actually telling him it is ok to go indoors, this can confuse the pup.
Put him outside Immediately he wakes up, after every meal and every play session. Stay out there with him and when he wees give a special word for it 'have a wee' for intance, and something different for a poo. Eventually you will be able to send him out with those commands.
If he continues going around the house then restrict his movements, don't let him in the lounge or on the sofa until he is housetrained.
It is down to your diligence to how quickly he learns.
Good Luck
