Thread: IMPORTANT! If you want HELP in case of a bricked Garmin device, please follow this

I have nuvi 4592. The fault problem is below:
1. It stop at Garmin's logo after power on, and cannot loading the map.
2. Press and hold the "volume up" key and start the machine at the same time. The screen displays a small red triangle, which lasts for about 2 minutes and then returns to Garmin's logo screen.
3. After connecting the computer with USB cable, the sound of successful connection of USB device can be heard on the computer, but the navigation device can not be seen in Explorer. From the device management, we can see that a "portable device: MTP USB device" is added.
4. Press and hold the upper left corner, upper right corner, middle corner and Garmin's G letter position respectively, and there is no response at the same time. It is the same phenomenon as questions 1 and 3.

Find a solution，thanks.
