[Q] i've messed up my kindle fire 1st gen topic

Hi please can anyone help,
I was trying to put a standard rom onto my kindle everything was going ok re rooting etc and I have twrp on there , Somehow in twrp I have managed to mess up all of the partitions probably through accidental wipes. My drivers seem to be installed ok but can't access the disk through windows or via adb it just says "device not found" ad I'm unable to mount the device either. Please help as I'm losing the will to live.
I have attached screens if that helps
