    G'day GK3000. Welcome to GPSPower.

    Try this solution from Garmin Support FAQ using WebUpdater with it in preboot:
    Code:
    Please Login or Register to see the links
    *However, 'Loader Loading' message appearing on screen seems like either it's in pre-boot already, or it's trying to load an update to the firmware and the GUPDATE.GCD file on the device file is corrupt. If that Garmin tip is no help, check our [Only registered and activated users can see links. ], scroll down to 'Garmin doesnt boot? Bricked device? Troubleshooting' and read the first 4 or 5 threads listed below there to help you unbrick/reformat your astro.

    Post again in one of those threads as appropriate if you need further help.

    *PS: If it's in preboot it will only stay in that for a limited time and then go to the calibration screen. If it's 'bricked' by a corrupt gcd file it with stay on the loader screen indefinitely unless forced off, or it'll turn itself off or reboot eventually.

    YES, If it's 'bricked' by a corrupt gcd file it with stay on the loader screen indefinitely unless forced off, or it'll turn itself off or reboot eventually. to power off as removed battery.

    not detect pc, to remove gcd file.

    Is that a question? If so i already told you how to do that in Post #2. To recap: either [firstly] reload a fresh copy of the gcd file using WU in pre-boot mode as detailed in the Garmin FAQ answer i gave; or if that doesn't work then read all those suggested threads in the Tutorials but especially [Only registered and activated users can see links. ] which gives the actual tools to load a 'cure' firmware to then access Mass Storage Mode so you can remove the gcd file manually.
    Please post in one of those existing threads if you need more specific help. This discussion thread is now closed sorry.
