There are some fresh KingSong S18 EUCs back in the Speedy Feet warehouse, as well as some spare parts for anyone that already owns an S18! Check out the shop if you've been thinking about getting one - https://www.speedyfeet.co.uk/products/kingsong-ks-s18
I will make a seperate post about the issue but in short, it was a combination of my android phone and poor coding on the part of KS. Essentially, i just had to use a more up to date phone to Unlock the KS S-18.
I just wanted to personnally thank you for your assistance last week and ask that you please pass on my regards to Ian :-)
