    Behind the spoiler are instructions and a ready-made pack which doesn't require preboot:
    Spoiler:
    • Set the device to Mass Storage Mode and REMOVE any gupdate.gcd file from the .System folder (see steps 1 & 2 in initial post by big-bang).
    • Extract this RAR file directly to a clean microSD: [Only registered and activated users can see links. ]
    • Ensure your nuvi 57 is completely OFF, not just in standby.
    • Insert the card and power the nuvi on (if battery is low, connect it to a suitable power source but NOT a PC usb port).
    • 'Loader' or similar should appear on screen and then it should boot normally and have patched firmware.

    WARNING TO ALL POTENTIAL USERS OF THE ABOVE PACK: This is for use in nuvi 57 or 58 HWID 2087 ONLY. If it's used in another device with different HWID it will be hard-bricked, probably permanently. It is your responsibility to check compatibility and assume all risk. All care has been taken in preparing this pack however I haven't been able to test it on an actual 57/58 before posting this.


    PS: I'd forgotten to mention that I've added a command to copy the nonvol region 154. After the flash it will show as '154.bin' with the other 3 existing bin files in the card's root. Keep a copy of it safely for the life of the device. It's a 'lifeline' backup that maybe one day can be used to revive your device.

    It's no secret. The method has been known for some time of using txt commands executed by Ldr.bin (boot.bin) on a media card for both dumping [rrgn] and overwriting [xrgn] regions that way and also using other commands such as ergn, copy, copydir and del etc.: [Only registered and activated users can see links. ].

    Provided the folders and files are properly made, the method is safe. The biggest risk is using a wrong Ldr.bin which has happened even to reasonably experienced users. The method is quite indiscriminate in that there is no inherent safeguard against incorrect flashing so a foreign Ldr.bin will be happily used and that will effectively overwrite the existing Boot BLK and X-loader so then the device may never boot again.

    As your 57 has now already had a patched firmware loaded to it, you can update it with a patched GCD file in future just as if it'd been done this time with an RGN. That's provided you don't load an ORIGINAL firmware again in the future, as doing that will restore it's protection against unlocked maps and you'd need to resort again to patching by RGN or the SD card method.

    @nicrus
    Follow the step-by-step in initial post carefully and then read the troubleshooting guide in second post if you have problems. Post again for specific help after that only if you're stuck or confused.

    Similar concerns and request for firmware addressed in [Only registered and activated users can see links. ]. Provided the firmware for the device's HWID is patchable, the version doesn't matter(see in patcher's hwid.txt file: 1697=Nuvi 53/55/56). See here for V5.60 firmware download: [Only registered and activated users can see links. ].

    I think I do everything as in the description of the patch.
    but I can not start the update at the end.
    what could be the problem?
