    It may be a "localized" version of 200i, perhaps made for a specific market. Without the original fw it's hard to help you. If you can access the hidden menu behind the battery symbol to find the PBC/PN and it matches the one for the device with HWID 3433 then it may be possible to use that fw's boot.bin/ldr.bin to dump the regions.

    NOTE: It might also not be capable of dumping regions if the rrgn command is not written in the fw.

    Default Butters is King of Garmin :)

    You are unbelievable!

    Good job!
    You're right again.

    When I changed the folder name from 3508 to 3433, everything was OK.

    There is not the hidden menu behind the battery symbol and everything works with "1:/" in commands. Mark 1:/ is micro SD card.

    I've just noticed your post [Only registered and activated users can see links. ]. Seeing you've been able to use the Ldr.bin for HWID 3433 to dump regions, it may be possible to fully convert to HWID 3433 by flashing an RGN file in preboot or use xrgn commands to flash the BIN components. The "K" version limiting the use of TT15 collars may then be overcome. There's still always the chance you'll brick it of course so all risk is yours naturally. Best to compare the fw_all 14.bin and logo 16.bin from the fw with the ones you've dumped, i'm tipping there will be some difference ... most likely in the logo region (decimal 16/hex 0x10). Use a hex reader or compare hashes.

    I did backup for all regions on Alpha 200i K few hour ago.

    There are backup just for regions 5,12,14,16,34,43,45,48,83,144,152,154 and 180.

    I have error message for regions 3,10,17,19,21,44,46,49,50,51,74,75,76,77,90,93,99,100,102,123,131,134,135,136,166,245 and 248.

    I have message "Success" for all other regions from 1-255, but they have 0 byte size.

    I hope that this informations are useful for somebody.


    @Butters Thank you for help again!

    Maybe already passed in this topic, but otherwise can be helpfull for others

    I created a nonvol Backup of my Zumo 345LM
    After a few failed attempts I found the right settings in update.txt

    Code:
    Please Login or Register to see the links
    I inserted the prepared SD card with ldr.bin in the zumo and switched it on.

    and that one did the job!


    I see a 154.bin with 4.194.304 bytes file size.
    Logs show also ok.

    Hi, I'm trying to make a backup, but to no avail ... I did everything as written in the instructions, I tried:
    rrgn, 41.1: /41.bin
    reboot
    rrgn, 41.2: /41.bin
    reboot
    rrgn, 154.2: /154.bin
    reboot
    but there is no "backuup.bin" file on the SD card
    Or how do I know that a backup has been saved?

    Things to check:
    • Do you have Ldr.bin and correctly named update.txt (NOT updater.txt) in HWID folder?
    • If there's a file named "last_id.bin" in HWID folder you must remove it. Try placing an empty file named update.log in there (make one with Notepad).
    • Do you have correct naming of HWID folder (use same HWID as that of the Ldr.bin in it)?
    • Do you have correct folder layout? Garmin\Updater\xxxx where XXXX is 4 numerals of HWID, e.g. US/EU firmware version zumo 595 has 2436
    • Try a different microSD card, some don't work in some device even if they work in other Garmins.
