Solved**, I had to manually install the MTP driver files, all ports both 2.0 and 3.0 now work, and on the T61 and T430, also an interesting find was that the computer cant access the phone when screen/phone locked, a nice security feature, no traffic from laptop to phone possible, All good now, thank god. Today I have read horror stories about people resetting their entire laptop to fix this issue, no way was I doing that! Took a while but I got there in the end.
Right click phone in device manager (yellow exclamation warning)
update driver, select from PC
Then select from Drivers on PC, select MTP driver, boom all good, Files can only be transferred when mobile is UNLOCKED!
