    you are absolutely right neil. i have so many 41.bin files in the unit's RWFS. all of those i have created with so many file names are in there. that's one thing to note also.


    way to find out is...
    View Map....
    Press Speed....
    Speedometer shows up.....
    Press the center of the speedometer for few seconds until the Diagnostic Page appears.....
    Scroll down to RWFS Settings...
    Tick "Show in Mass Storage"

    Exit the Diagnostic Page and shut off the unit.....
    Connect your Unit via USB to your PC and in your Computer Drive, you will find 2 Garmin Directories one of them will be the RWFS which contains hidden file .System and your 41.bin file....

    (this is assuming that your MTP settings is set to "Mass Storage")

    Thanks, it may not be widely known how to do that. Some pics on how to show RWSF in MSM are in Alviora's post here: [Only registered and activated users can see links. ].

    I posted this question [Only registered and activated users can see links. ], but was advised to post it here too:

    I have a nüvi 250 with HWID 0834 and FW 3.80 but there's no GUPDATE.GCD file in the Garmin folder. I believe this FW version has not been shared here yet. Any way I can extract the FW file from this unit and share it at GPS Power?

Giomen's answer to you in the previous thread about obtaining copies of regions 12 & 14 [boot.bin and fw_all.bin respectively] is only partly helpful because although 14 can be dumped successfully from 2x0/2x0W units, region 12 dumps but is empty so i believe it's protected. Region 5 dumps but is not a complete 'boot.bin' of course, and also there's the question of what you'd to use as ldr.bin in any case as raised by Giomen. kunix's or similarly qualified help is needed with this i believe and maybe open forum isn't the place for talk of ways to overcome dumping protected regions anyway .

    Hi to all.
    I have 3770V with 2.6 firmware and I can`t copy Region41 like I copy from my 3490 and 3790. Is there any spacial procedure for copying region41 from this 3770V?
    The other strange thing is that I can`t update the software version form 2.6 to the last one, and there is no UPDATE.GCD fail in .System directory too.
    Can you advise me how to copy the Region41 from my 3770V?
    Thank you!

    I am confused here. Post #1 says:
    "4-In the above folder copy Ldr.bin . What is Ldr.bin? It is your firmware boot.bin you can extract with RGN_tool".
    But there is no extract button in RGN_tool. Under File there are Open RGN/GCD, Save to RGN, Save to GCD. Under Tools there is MP3 Patch. Under Help there is only About. That's all. I assumed that once I connect my Nuvi 3490 to my PC and run RGN_tool it would recognize my Nuvi and pull that Ldr.bin out of it. Perhaps I am wrong. Need help. Thanx.

    No, you need 34xx firmware and save its boot.bin as .rgn by RgnTool

    Ok Catymag,THANK YOU VERY MUCH!
    I made it. It write the Region41 fail, I didn`t know that the HWID for 3770 is 1406, but in the log it is written:

    nьvi blade Series Software Version 2.70, UID: 384356xxxx, HWID: 384356xxxx
    ------------------------------------------------------------------------------
    Parsing "if_error,rrgn,abort"
    Error: invalid command 'if_error'
    Error
    Parsing "rrgn,41,1:/41-backup.bin"
    Success
    Parsing "reboot"
    Success

    And why there is an error in If_error?
