    only once I managed to get the partitions read with sd magic inserted, I tried to uninstall the patch but it invited me to apply adb root. nothing happens I unplug the usb cable and finish the procedure with done!
    then I go back to remove the patch but can't find the tomtom. once he even saw two and invited me to unplug one.

    I managed to put it in recovery mode and I installed adb root (very slow) reboot in normal mode and when I go to remove the patch it does not see the tomtom. @marky1991yes I have successfully backed up

    very slow copy adb + root is not normal is a small file, bad memory bad or bad connection.
    he says he got put in recovery mode, try to put the backup he did first when he worked well and see if he solves.

    If I manage to go into safe mode, when I try to run adb root (very slow) at the end I get this message ...

    The superblock could not be read or does not describe a valid ext2/ext3/ext4
    filesystem. If the device is valid and it really contains an ext2/ext3/ext4
    filesystem (and not swap or ufs or something else), then the superblock
    is corrupt, and you might try running e2fsck with an alternate superblock:
    e2fsck -b 8193 <device>
    or
    e2fsck -b 32768 <device>

    Done !
    Adb and root shell is now enabled on your device.
    Reboot the device in normal mode

    if instead I try to perform the recovery partition it sends me this:
    Drives now connected :
    /dev/sda = Crucial_CT525MX300SSD1
    /dev/sdb = ST3500418AS
    /dev/sdc = ST3500418AS
    /dev/sdd = TomTom GO USB Device
    => New drive detected /dev/sdd = TomTom GO USB Device
    WARNING : This will re-write the recovery image to device /dev/sdd3. Are you sure ? (y/n)?y
    Ok, let's do it !
    dd: failed to open '/dev/sdd3': Read-only file system
    End !
    If it does not work, try the following with device working in normal condition
    adb connect 169.254.255.1:5555
    adb push recovery_partition.bin /tmp
    adb shell
    dd if=/tmp/recovery_partition.bin of=/dev/block/mmcblk0p3
    (or mmcblk1p3 if a sdcard is inserted)

    @yjoliva, one thing you have to do is try to turn off the Windows antivirus completely, because I too have had these problems, it seems strange but it is not.

    Hello, I have same problem black screen with tomtom logo.
    It beginning after installing root. (i did'nt install patch yet)
    I can hear only half drums sound when start my go510 and then it reboot and it stall in tomtom logo black screen backlight.
    Tomtom is recognized from pc only with magic card inserted.
    I am able to reinstall root with sd magic inserted but it still have same problem
    How can I do?
    I use windows 7 and I red in this discussion, maybe I can use linux or another software to go inside nav4 and replace boot files from another go 510 (I have another one working fine).
    Please suggest me a way to solve this problem
    @simba pls

    important is backup of this device?
    do NOT use a copy of another
    if you use an ubuntu example, look on records or write terminal; sudo fdisk -l and check if sees 2 partitions, one less than 128KB, other approx. 8 or 16 GB
    if you see these 2 partitions with app discos, create a copy of this particon and with an exadecimal editor opens it and check if you see your device number
    comment and continue.
    regards

    maybe I already did it a bad thing... someone suggest me to use a backup of another same device
    I did it but after restoring that backup, and power on, my nav shows only backlight without tomtom logo or drums sound.
    It stall and reboot only with backlight on and off.
    I tried to insert magic sd and use nav4free to installing root and it done!
    It is recognised by pc only inserting magic sd and using nav4free
    I cannot go in normally recovery mode to use MDC or I cannot normally start tomtom..
    I cannot go in recovery mode with pushing 3 power on button method..
    I never use linux (sorry.....) , I work on win7.
    But if you tell me how to try to recover my tomtom, and wich software, I will try at the best I can..
    Thank you so much

    by putting a copy of another device, you have broken yours, to have the option of recovering it is essential to have a copy of your device, at least the 128KB partition.
