本日26日は天気も良さそうなので自転車と思っていましたが、もの凄い強風が吹き荒れております。ちょっと危険なので今日はパスとしました。
先日このブログに、Oregon450 の復活方法を問い合わせてくださった方があり、私も忘れていましたので備忘録代わりに書くことにしました。元の情報は、ここ http://sites.google.com/site/topolusitania/Home/ver-os-mapas-jnx-nao-oficiais-no-gps です。
大事なのはこの部分。
Is there any way to recover a corrupted Oregon without sending it back to Garmin?
Warning: This procedure may delete information (waypoints, routes, tracks, etc) from your GPS and settings may be set back to factory defaults. It is intended to be a "last ditch" recovery procedure.
There are two recovery procedures you can try on your Oregon. The first can be use to solve problems where the unit cannot boot because it gets stuck loading maps or gpx files that might be corrupted. The second procedure can be used to recover a unit which will not start properly after software upgrade.
Recovery #1 -- Forced USB Mass Storage Mode (only available in release 2.85 and after)
If your Oregon freezes during the startup process (i.e. Loading Maps...), and you've just loaded new maps or new gpx files then it could be the new files which are causing the problem. This procedure forces the unit into USB Mass Storage mode so that you can delete (or rename) these files. Follow these steps to recover:
1. Attach the Oregon to your computer via USB cable
2. The Oregon will power on and start to boot, immediately power the unit off while still connected
3. Power on the Oregon and continue to hold down the power button for 30 seconds
4. The Oregon should enter USB mass storage mode
5. From your computer remove or rename any gpx, map files (.img, .kmz,jnx) files that were recently added
6. Unplug the Oregon and power on to see if this remedies the problem
During step 3) you should only see the Garmin banner for 30 seconds followed immediately by the graphic that shows a computer connected to a GPS. If you see any other text such as your custom banner, banners for loading maps, waypoints, etc then you have not held down the power button long enough.
Recovery #2 -- Forced Upgrade using RGN file
This procedure may be useful if you've recently performed an upgrade and the unit no longer works. The procedure will force a low level installation of the software. After running this procedure the Oregon will be running the version of software provided in the RGN file so it may be necessary to run the Webupdater once you are done to upgrade to the newest version of software.
First you'll need to download the correct recovery file based on your device type (Oregon x50, Oregon x00, Dakota). Once you've downloaded the zip file extract it to your C:\ drive using a tool like WinZip. Once the extraction is done you should have two files: C:\Recovery\Updater.exe and C:\Recovery\GUPDATE.rgn.
On your PC click the Start menu, select "Run..." and type "cmd" where it says open. A black window with a DOS command prompt should appear. At the command prompt enter the following command:
> cd c:\Recovery
At the next command prompt type the following command without hitting enter:
> Updater.exe GUPDATE.rgn
Now back to your Oregon.
1. Disconnect the Oregon and make sure it is powered off
2. Press and hold down the power button and do NOT release the power button until step 6).
3. Quickly plug the GPS into your USB cable connected to your PC
4. Back on the PC hit <enter> to execute the command above, this should bring up the Updater window
5. Select the USB radio button
6. Wait for the "Loader" banner at the top of the Oregon screen above the Garmin logo and release the power button
7. The GPS should display "Software Loader" and Updater should show a download progress bar.
8. The GPS will go through several update / restart cycles.
9. If everything goes well the Updater will give a success message and the Oregon will restart running the version of software in the RGN file
10. Run Webupdater to make sure that the unit has the most up to date software.
If you don't perform steps 2-4 within about 30 seconds the Oregon will end up in USB mass storage mode. If this happens you will need to start over. In step 6 you have just a split second to release the power button at the right time.
When you plug the Oregon into the computer in step 3 you might be asked to install the Garmin USB drivers if this is the first time you have executed this procedure. Allow your PC to automatically update the drivers which should be available on your PC if you've installed Mapsource. If not the USB driver can be downloaded from Garmin.
If you would like to use this procedure to upgrade to a different version from the one provided in the recovery file above go to the Versions or Versions x50 page and download the gcd file for the version you would like use. Download and run TurboCCC's RGN_Tool to convert the gcd file to a rgn file and use that rgn file instead of the one included in the recovery file. This tool has been used successfully with the default settings but please see TurboCCC's wiki for the latest details on how to use this tool.
私の場合はハードリセット(画面の左上部をタッチしながら電源オンだったかな?)ではダメで、ここにあるカバリー1で復旧したように思います。リカバリー2ではコマンド実行が必要だと記載されていますが、実行した記憶がありません。(ただしPC内にはダウンロードしたファイルがありました。)
もしお困りの方がおられれば、ご参考まで。。
