How is the hard reset done on a touchscreen device (7612xsv)? Thanks.
I'm not sure, but try to use the following procedure:
1. Power on the chartplotter
2. As soon as 'Garmin' appears, press and hold the Upper Left corner of the screen until the message 'Do you really want to erase all user settings?' appears
3. Choose 'Yes'
NOTE! Pre-save your user data (waypoints, routes, Auto Guidance paths, tracks, and boundaries) to an SD card since after such a reset all this data will be erased.
Thanks for the information. I tried it this morning, but the machine booted normally. I then holding down the power and the left hand screen corner. After a short period of time, the message "Transferring to recovery area" and then "Recovery loader area ready". I tried pushing the various corners but was unable to make anything happen. Pushing the power button shut the machine down. Powering up normally showed nothing changed. I'll try some different combinations later.
The 'Recovery Loader' you encountered is how you do 'forced updates' of the software on the unit. Normal way of upgrading the software will not allow a version earlier than that in the unit to be installed. Using a forced updates with the recovery loader is how you can install an earlier version (i.e. do a rollback) of the software. You need to have that earlier version on an SD card (same process as that used for a regular update) and the do your power/screen hold to bring up the recovery loader.
Version 10 of the software for your unit has several enhancements, including the anti-piracy routines that prevent unlocked (non-genuine) Vision and other non-Garmin cards from working. The last version of the software without these 'enhancements' is here [Only registered and activated users can see links. Click Here To Register...]
That depository has a very slow download speed for non-subscribers so be ready for the download to take quite a while. Make sure you hit the right download link since there is a lot of garbage there.
Thanks, that sound encouraging! Turns out that holding the power button is all that is needed to enter that mode. I still have all of my previous updates so shouldn't have a problem. I'll give it a try tomorrow and report back on progress. Thank you all for your help!
This way of entering the Boot Block mode has long been known.Quote:

Now we would like to know how to enter the Master Reset mode on the touchscreen GPSMAP 74xx/76xx series ...
I was unable to find any to make the rollback happen. It goes through the motions, but version 11 refuses to give up it's hold. Very discouraging! I can get by with a laptop running my homemade charts, but I shouldn't have to. Garmin's Quickdraw contours simply won't work here as we have as much as 23 feet of tidal change. One foot contours won't cut it either. Looks like Simrad or Furuno in my future.
Have you read my [Only registered and activated users can see links. Click Here To Register...] here?
Pay attention to the 'updates' folder! And also see the Note there.
Once again, thanks for the information. I read the posts and their individual links and tried to copy those techniques as much as possible.
I ran GPSMAPSerieswithSDCard_20170825.exe which placed GUPDATE.gcd and the folder “updates” on a blank card. I placed it in the machine and held the power button down until “Transferring to Recovery Region” appeared. I released the power on button at this point. After 15 or 20 seconds, the machine started the update process which still ended with software version 11 still installed.
I noticed in message #11 that GUPDATE.gcd is the only file that should be on the card, no “updates” folder. I tried this, but nothing would happen until the “updates” directory was returned.
Also, I’m wondering if running GPSMAPSerieswithSDCard_20170825.exe is what I’m supposed to be doing. I’m getting the impression that files are supposed to be extracted from the executable which is probably way beyond my skill set.
Thanks again!
