Good Day,

Glad to be a new member of the group.
I have bricked two Garmin Nuvi that were charging in a USB Hub on my windows 98 computer.
One is a Nuvi 255W, it just keeps trying to reboot, I can get to behind the scenes and can create some ear piercing noises.
The other is a Nuvi 40LM - that freezes at the Garmin logo screen - No shortcuts to press buttons to get to the behind the scenes works.
Garmin tech support said the devices are too old and had no thoughts other than I might have fried something.
Tried looking for the original software to no avail.
Did find something on archives.org - 2 hits one had more files than the other.
Anybody think I can salvage either of these even if it means running it off the sd card if I can't get it back into the device?
I was reading about the other posts about un-brick, Cure3, rmprepusb on this nice webpage.
Thanks in advance for any help.
