Read through the 6.2 upgrade thread. You'll find links to download the 6.2 slices via emule as well as the procedures and processes required to install them for a 6.2 upgrade without disturbing anything else on the Tivo. The thing is, you'll need to hack your 3.1.1 OS in order to get the files transferred. The good news is that the hacks will remain in effect after the upgrade, although you'll have to copy them over to the new set of partitions before you reboot in order to preserve them.
Please don't PM me or any other members looking for personal assistance. You'll do better by posting (after you've exhausted the search feature, of course) and taking advantage of the collective expertise of the membership instead of a single individual that may or may not be able to help you. Thank you and enjoy your stay at DDB!
