Reply With QuoteYou don't need cure firmware., you just need original US gupdate.gcd saved to .RGN file by RGN_Tool to flash your US 3790 back to use original firmware.
Hard reset won't help.
You need
1). updater.exe
Download link ::2). RGN_Tool ( [Only registered and activated users can see links. ] )Code:Please Login or Register to see the links
3). .RGN file I said above.
4). Access to pre-boot mode for flashing nuvi back

3790 in endless boot loop
If someone could please help. I have a US 3790, just arrived yesterday. I tried to update with Thai firmware 2.10. Now it is stuck in an endless boot loop. I cannot do a hard reset. I have turned it off, then tried putting my finger on both the lower right and the upper left corner while booting, and it doesn't work. It does not show up in Windows Explorer for me to use a cure firmware. What can I do?
Here is a video of it: [Only registered and activated users can see links. ]

But I cannot access the device. It will not let me do a hard reset. It does not show up as a USB device in Windows. Updater says no usb device connected. Even the Garmin website cannot detect the device. What can I do?

Pre-boot mode
1). when garmin logo appear., press your finger above "G" of "GARMIN"
2). you will see a little "system"
3). now you are in pre boot mode
0).on computer.,--> drag rgn file on updater.exe., -->select USB
1).Plug in usb with 3790
2).access pre boot mode
3).when you see "system" on 3790., plug in usb into computer
4).You will see your device detected on Updater.exe
5).Press OK on updater.exe
6).Still press your finger till complete updating firmware.
Good luck

Ok, first I would like to say thank you very much Khun Aekhong, your help was the only thing that helped me fix this issue. I still can not find any information about this on the internet, yet you were able to help me so quickly. Again, thank you.
I have resolved the problem. I tried many times to use the updater with several different rgn files, without success. I even tried to make a cure firmware and that didn't work. Finally I was able to update the device and now it boots correctly with the latest firmware from US.
Now, please can you tell me what is the best firmware to update it to use the newest Thai maps with JV and 3D and Lane Assist? Is it possible to update this unit (3790T US) to the Thai firmware? Or will the SG/MY or CH firmware allow this? Your opinion would mean alot to me.
