I purchased a new 798Ci SI a few days ago and set up my unit on my portable ice-fishing box to "play around". It was working fine and I decided to register on the HB site and download the latest version of software updates. I have several MMC cards and rather than use a PC connection cable, I loaded the new version of software on the MMC. I powered up my HB, inserted the chip and began the update. I then was frozen. The loading screen was stuck running. I checked power and had clean 12.2VDC on my battery.
I ended up having to power down the unit and restart. At this point, the HB started in the MATRIX SERIES BOOT VERSION 4.300 Jul 21 2008 mode. I decided to try "reset" the unit and nothing changed. I checked each test option and everything was fine. I then began to do some reading here on the site for known issues with the software upgrade. By the way, I did reset the unit to defaults as directed.
I attempted to reload the software version that it was at when I received the unit by copying the file to the MMC card, powering up the HB and inserted the MMC chip. I selected the item 9 "program" and the unit proceeded to display "programming..." at the bottom. After approximately 1 minute or so, the screen scrolled to the next line reflecting "Failure".
I then found this site and downloaded every version of software for the unit. I proceeded to try each version with no luck. Each time I received the "Failure" response. I also tried different MMC cards to see if there was an issue with that to no avail.
I cannot power on the unit and get to anything other than the "BOOT" screen. What did I do wrong? Since my ice fishing setup has the transducer connected, is this a problem? Help!? This is brand new and already I cannot get this working. I hoped to get out to use this ice fishing in the next week but now things don't look good.
