Tied everything to root swift, cant get past initial fastboot stage

hi all, sorry if this has beeen posted before but its bugging me as i spent literally 4-5 hours lastnight trying to sort it, i havee rooted 4-5 android phones in the past but im just having no luck with this one

i installed adb / fastboot minimal, enabled what needed to be enabled in developer options on the swift, booted the swift into fastboot mode, then when i run adb on my computer, the first command works 'fastboot oem unlock' but after that its constantly saying 'waiting for devices' whenever i try the next phase of commands ie. fastboot -i 0x2970 oem unlock-go etc it just wont detect the device at all in windows on adb, is there any suggestions anyone could throw out there before i end up sending it back and getting an alternative android phone thats easier to root? the only thing i can think off is its a usb driver issue? but i installed the gloogle usb drivers and it picks up the phone for file transfer etc so im not sure if this is the issue. many thanks!

Is there any way to get Amazon's unlimited cloud stage in the UK?

I've been regularly checking, and it's now been over a year and we still haven't gotten any news regarding getting the same service over here. Whenever I try to sign up for it, it won't let me due to the fact that I'm based in the UK. Is there a way I can use the service despite being in the UK? I haven't found a guide with steps on how to do so anywhere...
If not, do you know of any other unlimited (<- important) cloud services that come close to Amazon's US offering in terms of price and quality?
Finally, I know XDA's probably not the ideal place to ask, but I know that you guys know your stuff, if you're stumped though, which other forums should I try?

Cheers,
