    How to Down-Grade your TomTom Bootloader (One/XL/GOxxx)

    1. First delete the "system" file on your tomtom
    2. Then copy the bootloader 0.0001 "system" file to your tomtom
    3. Start the tomtom up and it should have a message come up (please wait) and it will load the 0.0001 Bootloader on your tomtom.
    4. Now connected the TomTom to your PC again and Delete the "system" file on it,
    5. Copy the BootLoader 5.5128 "system" file to your tomtom
    6. Unplug your USB cable and you'll get the same (please wait) message and when the tomtom starts it will have the bootloader 5.5128。

    Remember using the wrong Bootloader can Kill your TomTom。


    错误升级的老机器已按照说明重新降档回低版本,使用上了流畅简洁系统。希望能给遇到同样问题的朋友一些提示。
    升级前后的机器信息截图如下:

    另外附上一些我顺带看到的关于启动档的不同版本的变化情况,置顶帖里提供的都是很好的版本,看的出来,是lu大版主们费心收集筛选提供的。有问题的版本都剔除了。

    Bootloader 0.0001 (One/XL/GOxxx)
    Very usefull bootloader to restore an original bootloader.
    Load bootloader 0.0001 and after that reload again original bootloader (ex. 5.5128 for One)

    Suggested (based on original TT CAB) & under testing (possible updates)

    TomTom One/XL = 5.5128/5.5136 (suggested) 5.5138 (under testing)
    TomTom Go x20/x30/x40 = 5.5229 (suggested) -5.5256/5.5259 (under testing)
    TomTom GO x50 = 5.5256 (suggested) - 5.5259 (nder testing)

    TomTom with Bootloader 1.xxxx = PLEASE DON'T UPGRADE THE BOOTLOADER

    Bootloader 5.5259 (Gox50)
    Bootloader 5.5256 (Gox50) official
    Bootloader 5.5242 (GOx10/GOx20/GOx30/GOx40)
    Bootloader 5.5229 (GOx10/GOx20/GOx30/GOx40)

    Bootloader 5.5138 (One/XL) under testing
    Bootloader 5.5136 (One/XL) official and sugegsted
    Bootloader 5.5128 (One/XL) suggested

    Thanks Alex

    --------- Bootloader suggested
    TomTom One V1/V2/V3/XL = 5.5242
    TomTom Gox10/x20/x30/x40/x50 = 5.5242

    --------- Restore original versionof bootloader
    1) Load bootloader version 0.0001 into TomTom root folder. Off/On TomTom
    2) Load bootloader you want into TomTom root folder. Off/On TomTom

    --------- Bootloader 1.xxx series
    REMOVED - VERY DANGEROUS
    PLEASE DON'T TOUCH BOOTLOADER 1.XXX - DON'T UPGRADE IT - YOU WILL BRICK YOUR TT

    5.5130 (One/XL)- Speed connect - Not sugegsted - Problem with USB - Long time copying file - DON'T USE!!!
