Right... FAT32 formatted the SD card and created a goldcard - all fine. Did all downgrade bits from one of the links - all fine. Copied correct file to root of goldcard - all fine. Rebooted phone (as instructed) - went to same menu as I put in the first post. Poopookakada - went to recovery (as you'd said). Got the phone with the red triangle with a ! in it... couldn't do anything, so had to pull the battery!
