Thread: Navicom Roads of Russia TOPO - Version 6.16

Now I got it how to decrypt Roads of Russia!


The simple way - no additional software needed but you need a previous version of Roads of Russia with same FID:

Take a sd-card, create a folder "garmin" in it, copy the previous "gmapsupp.img" into the folder "garmin"

Download the new version, unrar it and run "MapUpdaterAllxxx_yyyy.exe". "xxx" is the number of the release (eg. 514 or 616) and yyyy gives the FID (1280, 1790 etc).

Then you have to click through several windows, you have to accept the agreement and so on. The text is not very helpfull...

This takes some minutes and will update the "gmapsupp.img" in the sd-card.


The other way - software required but no previous version needed

This is done in three steps, some of these steps can be done in several ways.

First of all create a new folder "11" in the root directory.

First step:

Download the new version to "c:\11", unrar it and extract the "gmapsupp.img" from the unrared files "MapUpdaterAllxxx_yyyy.exe", "MapUpdaterAllxxx_yyyy-1.bin" "MapUpdaterAllxxx_yyyy-2.bin" and "MapUpdaterAllxxx_yyyy-1.bin" to "c:\11".

Two ways how to do that:

First way:

Run "MapUpdaterAllxxx_yyyy.exe". That will create a temporary folder into the folder where the operating system stores the temporary files. While "MapUpdaterAllxxx_yyyy.exe" is running you can see where to the img is extracted. Takes some minutes.

As soon as you get

[Only registered and activated users can see links. ]

you can copy the "gmapsupp.img" from the temporary directory to "c:\11"

Second way:

Copy "innounp.exe" to "c:\11" and copy the unrared files "MapUpdaterAllxxx_yyyy.exe", "MapUpdaterAllxxx_yyyy-1.bin" "MapUpdaterAllxxx_yyyy-2.bin" and "MapUpdaterAllxxx_yyyy-1.bin" to "c:\11"

Leftclick "Start" and then "run", type "c:\11\innounp.exe -x c:\11\MapUpdaterAllxxx_yyyy.exe" and leftclick "ok"

[Only registered and activated users can see links. ]

This will extract "gmapsupp.img" to "c:\11\{tmp}", move the "gmapsupp.img" from "c:\11\{tmp}" to "c:\11\"

Takes some minutes and this "gmapsupp.img" is xored AND encrypted.

Second step:

Unxore the "gmapsupp.img"

Copy "fxor.exe" to "c:\11", you need to have "gmapsupp.img" and "fxor.exe" in "c:\11"

Leftclick "Start" and then "run" and type: "c:\11\fxor.exe - c:\11\gmapsupp.img" and leftclick "ok"

A dos-window will open and when it closes after some minutes the "gmapsupp.img" is unxored.

!!the timestamp of the "gmapsupp.img" is not changed!!!

Third step:

Open the unxored "gmapsupp.img" with an Hex editor, Caty proposed "HxD"

In the third line there is written "ASKIMG", change that to "DSKIMG" and save this "gmapsupp.img"


Done! But note: the "gmapsupp.img" is decrypted now but it is locked still. You have to unlock it!

And many thanks to Catymag and pitruchio!!!
