Now get the current 0972 firmware [v6.20] from here: [Only registered and activated users can see links. ]. Then make and flash the cure fw as shown here: [Only registered and activated users can see links. ], then format it as shown here: [Only registered and activated users can see links. ], then reflash the original v6.20 fw and finally connect it to WebUpdater and MapUpdater to get your missing files. You can get another basemap from here: [Only registered and activated users can see links. ]. If you need other files like help or KBs we can supply them. Safest not to put any of your original files back from your backup as you have no idea which one's stopping it from booting.

Follow the procedure set out by smokefree in this: [Only registered and activated users can see links. ]. As Caty said, it's the solution. Everything you need is actually in there. smokefree spent a lot of time putting that together so that this sort of to 'n' fro would be minimised. Please read it thoroughly before you do anything or post again.
