    1) Do you remove last_id.bin?
    2) 1:/41.bin mean what 41.bin must be in root on SD...

    Talking

    an perfect example of common mistake related to Copy&Paste:

    nьvi 2xx7 Software Version 5.10, UID: 387xxxxxxxxx, HWID: 3xxxxxxxx
    ------------------------------------------------------------------------------
    Parsing "rrgn,154,2:/154.bin"
    Success
    Parsing "reboot "
    Error: invalid command 'reboot '
    Error

    extra space at the end of 'reboot' command caused error.
    Solved

    Whole backup process takes few seconds on my Nuvi 2xx7. However unit did not went in to reboot, simply loaded in to main screen. This unit has latest 5.1 firmware
    Succesfull log:
    nьvi 2xx7 Software Version 5.10, UID: 38xxxxxx, HWID: 3xxxxxxx
    ------------------------------------------------------------------------------
    Parsing "rrgn,154,2:/154.bin"
    Success
    Parsing "reboot"

    154_backup.bin from my nuvi 2599 is just 2048 kb.
    Does that sound reasonable? (I did see post #28).

    The backup log says success, and I repeated the process with identical results.

    Maybe it's reasonable, you can check it in a hex reader but it'll certainly be encrypted however and you'll see apparently empty padding. Nonvol region sizes vary between unit series and what you're seeing is the total available size of the region [2 MiB or 2048 KiB or 2,097,152 bytes] not the size of the actual information contained in it. The example is Post #28 is for a US/EU 3790 with HWID 1101 and it's nonvol region [rgn41] size is indeed 6,272 KiB or 6.125 MiB.

    I am having trouble with step 4. When I start rgn_tool all the checkboxes for the firmware sections are unchecked and greyed out.

    Should it be auto-detecting my GPS? My GPS (Garmin 2689 HWID 1948 SWV 8.20) is indeed plugged in to the computer by USB and is accessible in Windows (10) via explorer.

    RGN_Tool is NOT used directly with your device and nor can it detect a device in any way. It is strictly a firmware manipulation tool designed solely to view, save or replace various components [*.bin files] of a firmware file [*.rgn or *.gcd]. In this thread it's being used solely for extracting the firmware's boot.bin [Ldr.bin] to use in executing the txt command to save region 41 or 154 as a bin file [in your nuvi 2689 it's the latter region number, saved to '2' for the microSD path].

    Read the tut in Post #1 carefully again. Best you do it yourself but if you're still totally confused one of us will make you a kit suitable for your HWID of 1948.

    Hmm,
    Maybe my question should have been, if RGN_Tool reads the "firmware boot.bin" then where is that "boot.bin" file found? (I tried to read and comprehend every single word of post#1 but although I _am_ computer literate, I'm still stuck).

    And I agree... I'd like to do it myself.

    Thanks for the wink ... it made me laugh to myself instead of banging my head on the wall.
    Here's a picture of what I'm seeing...

    And if I check off the box (e.g. for Sect. 1) and try a 'save' then I get an empty (0 byte) file.

    Of course, because you've got nothing loaded. You must first OPEN an RGN or GCD file to see it's various BIN files. To do that either drag the file onto RGN_Tool.exe OR open RGN_Tool and drag and drop the file onto the GUI's 'File Drop Zone' OR open RGN_Tool and press 'File' > 'Open RGN/GCD' [or press the big 'Folder' Icon below 'File' button] then browse to the required firmware file. When you have the fw file open, press the 'Save' button on the first section holding 'boot.bin' and save it as 'Ldr.bin' to use with your text command. [More than one way to skin a cat ].

    If you're still stuck, here it is anyway. Extract the rar file to find Ldr.bin.
