Hi I am trying to cure nuvi 1100 using sd card method. It gets stuck in flashing garmin logo loop. It contains 4.00 sw. First I tried to cure it with garmincure3 tool using 4.00 gcd. Preboot mode was entered via top left corner trick. I see loader loading then sw missing message. Then I tried the sd card method.

I am not able to execute commands in updater.txt. Here is what I did

1) using rgntool extracted boot.bin from nuvi12xx_GCDFile__580.gcd. Patched it (replaced 0C 80 A0 E1 with 0C 80 A0 E3). Then unchecked other bin files and saved the rgn as 097101000580.rgn.

2) On an empty sd card (4gb) created Garmin\Updater\0971 folder and placed updater.txt. It contains the following commands
I am first trying to get files out of the device to sd card. I don't see any files being copied to sd card
copy,0:/Garmin/GarminDevice.xml,1:/original/GarminDevice.xml
copydir,0:/Garmin,1:/original/
copydir,0:/Garmin,1:/original
copydir,0:/.System,1:/original/System

copydir,0:/Text,1:/original/Text
copydir,0:/Voice,1:/original/Voice
copydir,0:/Keyboards,1:/original/Keyboard
copydir,0:/Help,1:/original/Help
reboot

I have another nuvi 1100 which works. I was hoping to copy files from good one to bad one via sd card. Any help is appreciated. I have also tried copying the 12xx files from this thread via sd card but it did not work either.
