Running programs from SD on nuvi

@kunix
I was just breeding "food for thought" because of that user on the other forum that did not delete GUPDATE.GCD as per your instructions.
Another issue. If I use LDR.BIN from the memory card version 5.8 on a 1300 running 6.00 after completion in the inventory screen it shows me.
Boot BLK xxxxxxx 5.80
X-Loader xxxxxxx 5.80
System xxxxxxxx 6.00
This tells me that using LDR.BIN from the Memory Card actually reflashes the Boot BLK and X-Loader.
Is this assumption correct ?

Yes, boot.bin contains the bootloader and the x-loader and flashes them when executed.
I see that many users are too lazy to follow instructions carefully. I don't like reading long texts and thinking too much either, so I can't blame anyone.
That's why I'm planning to create an utility which will patch boot.bin in a quite complex way, then send it to the device in the pre-boot mode, and then the boot.bin will format NV while preserving some important values (if you know what I mean

) and format the internal flash drive.
All the user data will be lost, but there are no need follow complex instructions.

When i look in FW for dezl760 found that this nuvi have SD 2:/
Old nuvi have internal 0:/ and SD 1:/
Dezl760 have internal 0:/ and SD 2:/

If you try to scan NVM on dezl760 with this command:

rrgn,140,1:/Garmin/140.bin

you have in updater.log success but on SD no 140.bin

If you add this command

rrgn,140,2:/Garmin/140.bin

you can scan NVM and you have 140.bin on SD

Two ports maybe? Maybe 1:/ is reading from USB

**lolypop000** · 22nd April 2013, 04:49 PM

I think tha 1:/ is for rwfs becouse if you look in FW you will see beside 1:/ only few .System folder but after 2:/ you see Garmin folder.

In New Fw is example: 0:/ .System/JCV .... 2:/ Garmin/JCV but on 3490 you have 0:/.System/JCV .... 1:/Garmin/JCV

Maybe 1:/ is a hidden partition or drive
Try to look with Computer Management Disk Management

The old Garmin wolfs! Why do you feed a bad example for beginners! Read this forum for example
