I also want to know it, because I have similar problem!
My friends gave me his phone, because it unfortunately didn't want to boot.
I tried to reflash it with stock firmware, upload goes OK, but then when it install the ROM, it says "failed to mount /data (invalid argument)".
I tried flashing also with .pit repartition and splitting the one ROM file into separated PDA/phone/modem...
I also wanted to try to flash custom recovery and then custom ROM, but it doesn't want to mount SD card also
EDIT: Solved! Look at this guide
After flashing open australia FW (including bootloader and pit re-partition) phone is working again!
Then just reflash with yours correct firmware
Do you have problems? Post logs!!!
