Help please to revert coil to v3.2

[Me and my boy]

I've just brought an 11" coil for my deus off eBay, second hand.
I can't get it to pair as I have tried lots of times. I think it must be v4 and my 9" is v3.2 as are my ws4's.
I'm only on deus lite and don't even have a computer.
If anyone in the south east of Kent could help I would really appreciate it.
I don't live near any detecting shops either so am a bit at a loss what to do.
Many thanks in advance

Cheers targets. I'm hoping I maybe able to find someone local, may have An offer from a nice chap, but neither he or I have done it before. He's still also on v3.2 and I don't want to cause him problems with his detector.

It's easy, go to the XP website and download the executable instal file it will say v4.0 don't worry when you open the install up you will see the drop down menu which lists all the versions including 3.2 just select and it will do the rest.

Many thanks. Can't wait to try my new to me coil.
