I was trying to flash my 2.6, the progress bar proceeded as normal, then shut off. No problem. But everytime I turn it back on, that Cromwell is still there. Both banks, same problem. Tried a different switch module, Voila!, there's the Xecuter BIOS, but only twice, then back to Cromwell. Turns out the motherboard (with a video problem) was blowing up the switch modules, but did no harm to the mod chip. Swapped the motherboard, changed the switch module (again), and I have a good box. Just a tip so you don't pull all your hair out like I did.
