HI guys, with the excellent guides on here I rooted my Hero a couple of months ago, and have had fun trying out new roms etc. Now however, it has developed a fault, in that it refuses to recognise any sd card at all. I have tried several different makes and sizes - all to no joy. It is still under warranty, but it has Villian 5.5 rom on it at the mo. Before I return it to the shop, how can I get the original rom on there without any sd card access? Any help/advice is much appreciated.
