Sram GX gear cable tension not working. Help

Hi all,
So I had to replace a fully functioning gear shifter cable from my 2016 Boardman Team 29er after I initially unbolted it so I could wrap a chain stay protector around the stay but open re attaching the cable the end split and I could no longer get it through all the holes.
Now I got a brand new official Sram gear cable and installed it as shown in many online tutorials. The problem I have now is that after I tightened the pinch bolt cable screw thing to the point just before it starts moving the mech towards the next biggest sprocket (yes I did have the chain on the smallest sprocket) the shifting to a larger sprocket no longer works. The lever for shifting on to a bigger sprocket is completely stiff and takes a lot of effort to make it click into the next gear and barely moves the cable when actuated hence no shift occurs. Shifting back into a smaller sprocket produces a very loud unhealthy sounding click as well. I have tried fiddling around with the single barrel adjuster on the shifter a million times but to no avail. When the cable is not attached the shifter clicks freely so it’s definitely not the shifter itself. Any help with this would be massively appreciated and if I can provide any more info or pictures to clarify the situation I’ll be more than happy to do so.
Thanks
