1. Why are you still flashing with HSPL2 when HSPL4 is available? You can get it here:
[FEB.20.11][DFT] HSPL4 - hTC HD2 LEO [DOWNLOAD] - xda-developers
2. If you already successfully flashed a hard SPL a few days ago, why are you flashing it again? Once you have successfully flashed HSPL you shouldn't need to do so again. If you are trying to flash a new ROM then simply flash a new ROM -- there is no need to flash a new SPL, MAGLDR, or radio (unless the ROM says you need to flash the radio).
