Have you made hard reset after flashing firmware ?
I'm a bit lost too, wondering what happened, if your nuvi didn't loose model n. as shown above not easy to understand what's going on in your nuvi.
You don't have Voice Command in About , see mine

I don't know what "Hard Reset" is!

Is there somewhere I could send my nuvi to have it come back working as a 3490?

Have you read starting post? How have you converted nuvi? Which procedure?
Must clear Non Vol (hard reset) after every flashing and follow the procedure with care or you can really brick your nuvi.
I guess you didn't backup NV too.

Disaster strikes! Used process to flash back to 3790 operation. After initial start up screen went blank. Waited about 20 minutes nothing happened. Now cannot connect to computer USB port, can hold on/off switch and looks like screen turns off. Hit on or hook to USB port and screen lights dimly in background.

Can't seem to get any further!

Is there any hope or is this now a brick?

Geoge, no panic!
Notice if after connecting the GPS appears a tenuous illuminated in screen. If yes, disconnect the GPS again pressing and holding the button on/off for several seconds to make sure that is not on stand by.
Turn on again and so that you see the tenue bottom lit, press and hold the upper left corner of the screen gps. Thus you go into pre-boot mode. Calm down,

Hi AngeloZip
Hard to be calm when you are in this kind of a situation!
Was a mix up on ebay and I purchased the 3790 by mistake, wanted the 3490! Rather than sending it back, I decided to simply load in the 3490 software. I had been here reading about the 3490 and 3790 prior to my purchase.
I thought this was going to be easy to do, never expected all the difficulty that I am having, getting to 3490 level!

Well, I tried what you said, and it indeed work and the message at the top said loading software, with the Garmin Logo and blue triangle in the middle of the screen. After about 20 minutes, I plugged it into the computer USB port. It immediately sent up an error message, something about not the right version of something and it shut down.

Now, a completely new situation, no matter what I try all I get is the Garmin Logo in the middle of the screen. Have tried to get back to pre-boot condition, but after about 20 tries it does not seem to want to work. And between each try, I held the off button for about 15 seconds, just to make sure it was going off.

What do I need to try next?

George, my suggestion was to enter in pre-boot to load a firmware (3790 or 3490 fw) by the update.exe. For some strange reason appeared after the Garmin logo. If this "logo" is of the 3490, to enter in pre-boot do as suggested by Lolypop, ie, just press and hold your finger on the "G" of "logo" Garmin. If the "logo" that appears is of the 3790 the position is different, ie, press and hold your finger just above the "G" of the "logo" garmin, or do as I suggested in the previous post (top left corner of the screen). Before you get ready to install the desired firmware with update.exe, as indicated at the start of the thread, so get in pre-boot.

p.s: Everything indicates that you have the firmware of 3790 with the logo of the 3490, so this locked. So to enter in pre-boot and reinstall the firmware that you want, start trying to press the letter G, but only when the logo appears on the screen, and not before. Alternatively, I believe that now may be the time to reinstall the 3790 logo (also by pre-boot) as suggested in the previous post by Loly and explained in the first post.
