Bit of background info: I've been fiddling with my 80GB CECHG02 running 3.70 using an Infectus 2 and I need to do a fresh 3.70 install. I cannot downgrade using the 3.6x method yet, but I'm getting ECC errors in one of my flash chips with the original 3.70 image. The ECC errors are at the same page every time. I want to do a fresh install of 3.70 to see if the flash is stuffed, the Infectus is not soldered correctly or if the image is corrupted.
Problem: If I try and do an firmware update from the recovery console, no matter what I do, it keeps telling me that the "data is corrupted" after it copies to the HDD. I've tried multiple USB pens, downloaded the 3.70 (official) numerous times; all to no avail.
Has anyone else had problems with a 3.70 install from a USB drive?
