HTC PPC 6800 (Alltel) reflash with current ROM image?

[prt7u]

Hi,

I'd like to start over and re-flash my phone with the current ROM available from Alltel. If I do this, will it "wipe" it clean? After I upgraded to the current ROM image after having the phone about a week, I had a problem with the "roaming" icon being on all the time. Turns out there was a config problem and Tech support walked me through the fix. Something about epsd or some such thing and a value not being correct and needing to be corrected. Can anyone tell me how to get back there so I can make sure that I know what the value is prior to "re-flashing" and thus not having to call them and get them to help me fix it again?

Thanks,

Pete
