I've tried all of that. Rename, download new copy, through ROM Mgr., through HBOOT, etc.
I can't get into recovery AT ALL.
I can't flash ANYTHING.
I can't try a new ROM or anything.
I'm sure the problem is I lost recovery.
So now the question is, to start from scratch to try to get this right & a clean version, should I just run Unrevoked again or do I need to UNROOT before I run Unrevoked again?
Ok so your file is named PC36IMG.zip on your sd card? So if you boot into your phone and go to a file explorer, ES or Astro or Root whatever it is you use and go to the the root of your card you see PC36IMG.zip in there.
If you are using ES file explorer it, by default, opens to the root of your SD card. I think Astro is the same, however Root explorer by default opens to / which is the lowest possible spot, so you would need to make sure you are in /sdcard with root explorer. You should see folders in the root of your sdcard like DCIM, downloads, clockwork, my docs, etc.
