Thread: GarminCure3 tool - the new way to create cure firmwares for Garmin devices

Does it only fail to boot when on battery power, or when also on charge? If it only happens on battery power then possibly your battery is near dead.

If it happens on charge, first backup and then try removing whatever file/s you last added e.g. gupdate.gcd, vehicles, keyboards, voices, map image, whatever. If it still won't boot format it with [Only registered and activated users can see links. ] and then if it boots replace files with MapUpdater/WebUpdater or GE. As it's visible in windows you shouldn't need to cure it. Read the initial post fully first please.

You can just format with prepusb and then create folder Garmin ( NOT GARMIN ) and see if xml will bi created.
If don't work, then try with cure, and after this flash with original fw in pre boot.

@bobokom

format it with prepusb and after this you also create empty new folder with name Garmin, when you turn off/on nuvi you will have xml inside and you can run webupdater and update all.
If all go Ok your nuvi will start normaly ( please, use webupdater for update your device ).

Nobody can help if you don't tell us what have you done (detailed)
1)have you entered preboot mode?
2)have you loaded kunix's cure?
3 have you format nuvi with RMPrepUSB?
4)have you loaded original nuvi fw?
5) have you created Garmin folder in nuvi and restarted it?

We can just keep on repeating these instructions, if we don't know what have you done precisely

Run this and let us know what HWID do you have in your nuvi 250: [Only registered and activated users can see links. ]

I'm looking in youtube for videos showing access to maintenance mode (preboot right?), like this



(I didn't find the nuvi 250: here he uses bottom left corner, but it helped me to understand I never saw the maintenance mode);

maybe my problem is I'm not able to get this stage (I press and hold upper left corner and then power, but always it appears the screen "WARNING...Agree"

On Noeman we have [Only registered and activated users can see links. ]

If you look here you will find: [Only registered and activated users can see links. ]

First you must install garmin usb drivers from garmin site

Code:

When you install this drivers, then read tutorial about pre boot for your nuvi.
