Recovery




If your Oregon 7x0 suddenly starts freezing or crashing during startup, it is likely a recently added map, image, gpx or other file that is creating the issue.



Forced USB Mass Storage Mode


The following procedure forces your Oregon 7x0 into USB Mass Storage Mode so that you can delete/remove/rename any recently added files:
  1. Remove battery and microSD card from your Oregon 7x0
  2. Connect the Oregon 7x0 to your computer with a USB cable
  3. As the Oregon 7x0 powers up and begins the boot process, immediately press and hold the power button without disconnecting the USB cable until the Oregon 7x0 powers down
  4. Press and Hold the power button for 30 seconds, or until the USB symbol appears on the Oregon 7x0 display
  5. The Oregon 7x0 will be in USB Mass Storage Mode
  6. Remove or rename any recently added maps, images, gpx or other files that may be causing the issue
  7. Disconnect the Oregon 7x0 from the USB cable
  8. Install previously removed battery / microSD card and power up the Oregon 7x0
  9. Repeat Steps 1-8 as needed until the Oregon 7x0 boots properly


Forced RGN Firmware Installation


This procedure (Windows only at this time) will force a low level installation of the Oregon 7x0 firmware. After completing this procedure the Oregon 7x0 will be running the firmware version provided by the RGN file. If an older firmware version is used, it will be necessary to run Garmin Express once you are finished to restore the Oregon 7x0 to the current firmware version.



Extract RGN from GCD

  1. Download and extract the desired GCD file from the Firmware page to C:\RGN\
  2. Rename the GCD file gupdate.gcd
  3. Run C:\RGN\RGN_Tool.exe
  4. Drag the gupdate.gcd file to the RGN_Tool window
  5. In the RGN_Tool window, select 'File | Save to RGN' and save as C:\RGN\gupdate.rgn
  6. Close the RGN_Tool
  7. Delete the gupdate.gcd file


Or skip steps 1-7 above and:

  1. Download and extract the desired RGN file (if available) from the Firmware page to C:\RGN\
  2. Rename the RGN file gupdate.rgn


The C:\RGN\ directory should now contain these files:

C:\RGN\RGN_Tool.exe
C:\RGN\Updater.exe
C:\RGN\gupdate.rgn


On your computer, click the Start menu, select "Run...", type "cmd" where it says open and press Enter. A black window with a DOS command prompt should appear.

In the command prompt, type: > cd c:RGN and press [Enter]

At the next command prompt type > Updater.exe gupdate.rgn and Do Not press [Enter]

  1. Remove all batteries from your Oregon 7x0
  2. Connect the Oregon 7x0 to your computer with a USB cable
  3. As the Oregon 7x0 powers up and begins the boot process, immediately press and hold the power button without disconnecting the USB cable
  4. Press [Enter] on your computer to execute the command typed above
  5. When the Updater prompts you, select the USB radio button
  6. When the "Loader" banner appears on the Oregon 7x0 screen, release the power button
  7. The Oregon 7x0 should display "Software Loader" and Updater should show a download progress bar
  8. The Oregon 7x0 may go through several update/restart cycles
  9. The Updater will display a success message and the Oregon 7x0 will restart running the new firmware


If steps 2-4 are not completed within a 30 second window, the Oregon 7x0 will enter Forced USB Mass Storage Mode. If this happens, restart the process.
