Shitty situation is what happened to me. I had a lot of devices connected to my laptop, 2 usb drives, 1 sd card and my garmin. and i had to format the SD card ( it was for my cell phone), but while choosing the drive to be formatted, i accidentally formatted my garmin and *BAM* gone. Hasnt booted since. Tried the Garmin Cure method. Managed to read as USB, formatted into FAT32 ( with and without quick format), reflashing to original firmware but nothing works. So thought i would try out the backup files from Lollypop. If that doesnt work im just gonna ask for a replacement device from the place i purchased it.
