How to backup Nuvi NV (region41) with sd

**forla** · 15th September 2019, 09:23 AM

Hello what commands i have to put in sd card to get all the regions of nuvi?

@forla
There are 255 possible regions for nuvi devices. Not all are present, or if even if they are present some aren't populated. Also, depending on model, the file system is contained in either rgn 48 or rgn 83 or in some cases duplicated in both. Therefore if you include those regions you need a large media card and have the device connected to a power source while dumping. Sample command:

Code:

Please Login or Register to see the links

Where "x" is the region number. You can include 256 commands if you wish to dump all possible regions, 1 to 255. Many will be empty or return an error in the LOG file but all of the populated regions of that particular device will be dumped.

thanks i will try it.

I have to do a different command for each region from 1 to 255?

Yes. Each command for each region on separate line with no spaces at end. Final command "reboot".

Is there way to backup regions for Alpha 200i?
I tried to do on standard way, but without success.

@miroslavbl
Please state what you tried and give a sample of *.txt command along with the folder naming you used.

Hi!

I made folder Garmin\Updater\3508 on micro SD card.

There are 2 files in this folder:

1. Ldr.bin (Boot.bin) from [Only registered and activated users can see links. ]
2. Update.txt
rrgn,5,1:/Garmin/reg_5.bin
rrgn,12,1:/Garmin/reg_12.bin
rrgn,13,1:/Garmin/reg_13.bin
rrgn,14,1:/Garmin/reg_14.bin
rrgn,16,1:/Garmin/reg_16.bin
rrgn,34,1:/Garmin/reg_34.bin
rrgn,41,1:/Garmin/reg_41.bin
rrgn,43,1:/Garmin/reg_43.bin
rrgn,45,1:/Garmin/reg_45.bin
rrgn,83,1:/Garmin/reg_83.bin
rrgn,91,1:/Garmin/reg_91.bin
rrgn,48,1:/Garmin/reg_48.bin
reboot

Nothing happened. There was not "Loading" phase and there was not Update.log file.

Assuming you have the device which uses that fw you linked (Note that Alpha 200i EU and US both have HWID 3433), it's not surprising that nothing was dumped. That would be because the folder naming of "3508" likely doesn't match the actual device HWID of 3433. You need to confirm before trying again. Additionally, if the device is MTP capable with a hidden RWFS partition then it will write to 2/: for the media card and 1:/ will write to RWFS. Additionally, the non-vol region will be 154 not 41 in that case.

WARNING: The chances of bricking a device by flashing the incorrect Ldr.bin are dire and most probably will result in a permanent hard-bricking. If your device indeed did have HWID 3508 it would now be bricked if the Ldr.bin was flashed to region 12.

You should check the actual HWID of the device itself before going further, read here: [Only registered and activated users can see links. ]

This is part of my GarminDevice.xml file:

-<Model>

<PartNumber>006-B3508-00</PartNumber>

<SoftwareVersion>320</SoftwareVersion>

<Description>Alpha 200i</Description>

</Model>

I bought device from Germany. There is mark "Alpha 200i K", but I can not find any software with this mark.
