My modem died a while back and was replaced with an external modem. Unfortunately, I never made a backup image for Series 1 SW version 3.0. My backup image (tivo.bak) was for SW ver 2.01 which does not support an external modem. I bought Instantcake, but it hijacked the serial port so my Tivo can not use a serial modem (external). Does anyone have a clean backup image (not Net Ready) for a Philips HDR 312 SW ver 3.0? HDR 112, 212, 312 will work. Does anyone need a backup image for Philips 312 SW version 2.01? If your Tivo internal modems works it will update to version 3.0 on second or third phone call.
