Hello everyone, this is my first time here. I have a 1490LMT for years that I usually use when I go to trips. Last year I refreshed the maps, went on a trip and used it with no problems. We came back and I stored it until 4 days ago when I decided to plug it in to my computer to charge so I can check if I needed to update anything before a trip I am planning to take. After being stuck on what looked at the logo screen for a while, I paid closer attention and realized that it was stuck in a boot loop much like a few folks described in the past.

Here is what I see:
1. Power on Nuvi 1490
2. Garmin screen for about 20 seconds
3. Quick blink with white screen
4. Black screen for a few seconds
5. Return to step #2 and repeat

I tried to review the whole thread but I did not find a possible solution. Here's what I tried up to now:

1. Plugged USB cable provided by garmin to computer
2. Run g7 and got the ID: 972, & version: 6.30
3. Downloaded GCD: nuvi13xxand14xxseries_GCDFile__630.gcd
4. Run GarminCure3 and added GCD
5. Clicked on "CURE" radio button
6. Clicked on "Make firmware" which made 097201000630.gcd
7. Clicked on Updater.exe
8. Clicked on "USB Device" radio button
9. While pressing and holding my finger in the upper left hand corner of nuvi screen (my finger remained pressed to the upper left hand corner throughout all the steps below)
10. Plugged the USB cable to back of garmin
11. The device booted with the screen showing the logo
12. As soon as the "USB device" appeared in USB box of the Updater window on computer, I clicked on "OK" to start update
13. I OK'ed the message that the version was the same and I wanted to proceed
14. The device now showed the screen showing the logo and right above it: "Software Loading"
15. The dialog showed "Updating". About 15 seconds or so later, the dialog showed "Erasing". About 10 seconds later the nuvi lost connectivity and a dialog popped up with the message:
"The GARMIN device is unable to program the requested memory region. This could be due to incompatibility between this application and the GARMIN device. If this error continues to occur, pleas contact GARMIN Technical Support."

So it seems that my nuvi does not stay connected long enough to CURE, and based on what I have read there is not much more I can try to get it to boot.

I have seen that in some replies, folks were given an zip file to try to boot from an SD card and see if they could write/read in specific regions of the nuvi, but most of the links are no longer valid. Does anyone have the files for that method for a 1490 so I can attempt that as a last resort?

Any help would be greatly appreciated.
