Dear DroidX2 many thanks, i try it soon.
i want reply you always in elementary mode (Step by Step) and copy/cut the links on this problem Google Play for help this community to show the procedure for not expert guys.
Sure Valis, I can do that once I'm in front of a computer, I'll post a full step by step. Currently this method is speculation based on what I did with the Snail W1 (78P01), but it's nothing extensive so it won't hurt to try.
By the way, I noticed from leaderbell opening post links the W3D is available through OYE on Amazon UK only, and I check their website directly and it's also available there.
On Amazon UK, I placed in a cart and to ship to the US the final was a few above 500 USD due to taxes, like 506 USD.
