sure ,point one of instructions is : Create a "Garmin" folder in an empty sd.
ok im bucking up with "rrgn,140,1:/140_backup.bin
reboot" and i se a green line and 2 cm down a big white symbol like a batery , how many time aprox do i have to wait because its 5 minutes or more ! " tnx
Its has been 1 hour and did not finish ,maybe is because i have 2gb and its need more , i dont think so. or incompatible memory ?
I power off ,and its power on ok , i will try again.
Because you wrote the wrong command. I guess.
It's not up to 2GB of memory.
You can make a mistake with dumping but not for writing.
I did it step by step i dont know what im doing wrong; In a clean SD " i saved boot.bin from nuvi34xx_GCDFile__710.gcd and renamed as ldr.bin and put it in /Garmin/Updater/1378 with update.txt with ''rrgn,140,1:/140_backup.bin
Its easy but it doesnt work for me.
