Don't put the GCD file back, it's not needed anyway. Maybe the map on the card is faulty. Remove the microSD card if it's still in the device, then flash the device with ORIGINAL (not patched and not cured) V5.50 firmware as an RGN in preboot and see if it boots. If it boots properly, turn it off and put the card back in to test.

Report back and don't worry as we have plenty more to try in steps if that doesn't work. Don't forget to tell us in full detail what you did first before this happened.

If not how do I flash the firmware and where do I get it from?
Please read my previous post and address the points in red bold. I can't help further until you do exactly what I suggested, you MUST load as an RGN file in preboot and you can load the original firmware using the Cure3 application (you should still have the original GCD that you used to make the cure RGN firmware from). You make the original RGN that the same way you made the cure RGN in the app except you press 'Original' not 'Cure' button. Follow this:

When the Updater.exe GUI opens, leave it visible on your desktop. Connect a USB cable to a REAR port of your PC (not thru a hub). Ensure the 3597 is completely OFF and put it into preboot by holding the screen and connect the USB cable to it which will power it on. At the very instant you see the device details appear in the window next to 'USB Device' on the GUI press 'OK' or hit enter key on your keyboard. Keep firm and steady pressure on the screen until the flash finishes:

If you're not sure that you still have the original V5.50 firmware GCD, you can get another copy here:
