Getting ROMs on my phone (Please Help Me!!!!!)

[infinitus]

I think I must have posted in the wrong section... because no one responded...

I put SPL-2.4.Olipro on my phone (barely got it on there... long story see below link) and then flashed using the Alltel download from the HTC website. All was well, it booted up fine twice. I hit the comm manager button and it restarted the phone (could have been coincidence, I suppose). The phone had no screen on startup. Just blank. The green LED came on and stayed on. So I tried to reflash with other things... with no luck. They all give me one error or another including comm errors, corrupted images, etc. So I used mtty to erase the roms on my phone (at least I think it worked) and had nothing changed; except that I now also get errors involving outdated nbf files and 'this upgrade is not for your phone' or something like that. I really don't know where to go from here. I tried using my SD card yesterday; and it just got stuck on loading... Now I read that it's supposed to do that? But I don't have the SD card tonight... Do I have the right process? Unlock - Radio - ROM ? Is there any way around the SD card besides downgrading to Oli 1.2 (obviously I can't use activesync with no Windows [can i?]). Thanks for any input... I really need help with this!
