Ok, I was on 6.60 and had some bugs, switched to 6.610 and interlink wouldn't stay connected to my 997. I tried to downgrade to 6.310, after the flashing screens quit it went to the loading screen and just keeps flashing "loading". It will let me open up on bootstrap mode, I am using the pcs3 cable from humminbird. Tried all different versions of Humminbird PC. I tried different sequences between turning on the unit and opening the software, but no matter what I do, it won't recognize tye 1197. I hooked up to my 997 through the pc and it connected right away and updated it with no problems. I hate to have to send it in and pay to have it fixed. Thanks in advance for the help
It won't let me run any software, just says no device selected or something like that. I sent it out today, tired of messing with it. I guarantee I will never update my software again. This was way too much hassle
Possible downgrade the firmware from version 6.610 is impossible.There is a bit of informationhttp://forums.sideimagingsoft.com/index.php?topic=5345.0
Need to read the whole thread...... There was a misunderstanding there all along.... It related to being locked into Humviewer...Straw
Kim,All they were saying here is (assuming that Martin does not ever update his HummViewer software): for your units to make compatible files to work with HummiViewer you will not be able to update your Humminbird units again. The reason for this is that the next version of software for your Humminbird units and every version after it would also have these same changes to the sonar recording files, which would not work with HummViewer. With all of the postings here Im betting that they should have done a better job of stating this.
Not sure.... it is somewhat cryptic.....BUT please don't skip over THIS:Plus remember Greg often sends update back outs from 6.57+ to people who request them....Straw
I do not understand how to roll back the firmware to an older version was able to turn the device into a brick. To such an extent that even the impossible to restore it through the boot mode.
That is why many people recommend NOT to update unless there are new features added that you NEED. Very few people are recommending the last three updates (6.57, 6.60, 6.61) unless you need 360 or Ipilot link..... Straw
The new GRP and GPS-HS should be no more accurate than the GR50 GPS Receivers we used before these.
