Here's what I found:
There are several things that could cause an error while upgrading the player, but one of the most common is a corrupted ".upgrade" file. Try using the GetRight utility to re-download the upgrade file. See if that fixes it.
Other possible problems are related to trouble with the serial port: Bad cable, hardware device conflicts, etc. Try performing the upgrade on a different PC.
It has also been reported that a bad pump error can be caused by a loose or faulty disk drive cable. Also, keep in mind that when the player is running on power from the car docking sled, the player's upgrade firmware won't listen for the upgrade command. Try performing the upgrade with the player running on power from the AC adapter.
Ok, I've ruled out the upgrade file problem because the upgrade file has been used before on my other units and this this unit with no issues.
Also ruled out the cable problem by upgrading another unit and had no problem. Additionally, fairly sure I don't have a PC conflict because this is the only PC I've ever used to upgrade this unit and my others.
So.... would a loose or faulty cable cause the playback distortion I experienced just prior to lock-up???? And furthermore cause my stuck or locked at boot logo issues???
My exact error message says "Error "bad pump response" occured during stage 0x25"
Thanks in advance for the help
