The typical curing algorithm (in general) looks like this:
1. Flash your device with the patched firmware (see below for more details).
2. Don’t disconnect your device from the PC. It should enter the mass storage mode and the PC should detect it as a new flash drive.
- If the filesystem on the flash drive is OK then you should try removing/renaming some files that could cause problems. Start from those files that were created/copied last. Don’t forget about making backups.
- If removing files doesn’t help, or you’ve accidentally formatted the flash drive into NTFS, or its filesystem is corrupted then you should reformat the flash drive into FAT or FAT32. Remember that when your device is cured you can restore most of the missing files by running WebUpdater.
- Unfortunately, some devices don't boot if the flash drive is totally empty (for example, nuvi 24x0). Then try copying it's contents from a healthy device of the same or close model. If even copying from the same model doesn't help then the problem is somewhere else, you need some other cure.
4. Flash your device with the original firmware (see below for more details), and see if it boots normally. If it still doesn’t boot then go to step 1.
How to flash your device with the patched or original firmware:
1. Download GarminCure3.exe and updater.exe from here: http://dl.dropbox.com/u/55759275/GarminCure3.zip
GarminCure3.exe user interface looks like this:
2. Download the original firmware from the Garmin website
3. Run GarminCure3.exe and open the downloaded firmware with it. You can do it by dragging the firmware file into “Input file” box or by typing the path to the file or by pressing the “…” button.
4. Press “Make firmware” button. Before doing that make sure the right option is selected from “CURE” and “ORIGINAL”.
5. If everything is ok, “Processing OK : )” message will be printed and all controls inside “Output file(s)” box will be enabled. If it doesn’t happen, please, let me know.
6. Then you can drag patched firmware files from the rectangle displaying their names. Or just run Updater.exe by pressing the corresponding button. The firmwares will be saved automatically.
7. Then put your device into pre-boot mode and flash the firmware with updater.exe. Search through this forum for what is pre-boot mode and how to flash devices with updater.exe.
Devices that can be cured.
The tool was tested on nuvi 200 (HWID=660), 6x0, 13xx/14xx, 22x0, 24x0, 37xx. So it should work for all nuvis.
Almost all Garmin firmwares are patchable (except some marine GPSmaps and linux-based devices), but this doesn't guarantee successful curing, of course.
Known bugs and issues:
There is an issue under Windows Seven and Windows Vista if UAC is enabled. If you want GarminCure3.exe to run Updater.exe then GarminCure3.exe should be run as Administrator. But then drag&drop won’t work.
Patched firmwares are stored inside GarminCure3-TEMP folder located near GarminCure3.exe. Don’t forget to delete GarminCure3-TEMP from time to time. Before deleting make sure updater.exe isn’t running.
P.S.
I hope this firmware is to facilitate work PouchX
