Thanks David,
As we discovered along the way, the image itself had some issues, but we figured it out.
I now have a fully functional Libra 2 running with a 256gb Samsung Evo sdcard.
Thank you so much for your help.
Oh, and some advice for if you're changing the sdcard in a libra 2, make sure that when you're pushing out the stock card from it's slot as per ILoveKobo's guide (

I found that when I angled the SIM card pin upwards a little, the card came out much easier.
I was getting quite frustrated with the card not moving until I realised I was angling the SIM card pin down a little too much & was probably pushing on the sdcard socket itself rather than the sdcard.
I hope that helps someone if you want to attempt switching out your sdcard.
