How about applying the undo package
directly from the SD card, i.e., putting the tmp and updates folder along with "PRS-T1 Updater.package" in the root of the sd card and then doing the home+menu reboot thing? Not sure if this would work if the normal sdcard-rescue doesn't, but it might be worth a shot?
