I think you will find it's nrear impossable to go back through software, the process only works if you use a higher software number.

But having said that, Try looking on Arsekick, or primeevil, for info on the J-tag process. which in effect completly strips all software and memory from the chips and allows a fresh start, with regard to software downloading.
