to properly do a hard reset you have to hold down the volume down+power+the center(action) button+hold on the soft reset button all at the same time. if done right you should receive a message stating that your device well be reset to factory settings. also, if you like you can flash directly from your memory card. if you like i can offer more details on that later. im not too sure what a .37 is but you can certainly take your pick from any of the custom roms listed on this site. i think one of these two may be your only option but anyone else can feel free to correct me.
