    This thread will drag out over 5 posts, sorry.

    This post is for people how want to root or flash a rom onto your device and you need to be in fastboot.

    This is how I got fastboot driver installed in Windows 7 Home Premium.

    1) You must have adb installed and working. There are threads around that will get you going on that.
    2) First you need LeTools as linked to Here. Install that file and make sure you know where it is.
    3) Then you have to Power On you device and plug in your A2109 via usb to your pc.
    4) Now from cmd prompt issue the command adb reboot bootloader this will put your device into fastboot mode and windows will not be able to find a driver for it.
    5) Open Device Manager and follow the steps below.

    Now follow the screen shots.

    Here is the device listed in windows

    $fastboot1.jpeg

    Right Click on Fastboot and select Update Driver

    $fastboot2.jpeg
    Select the next dialogs as shown


    $fastboot3.jpeg

    Then this one and click next

    $fastboot4.jpeg

    Brings you to the Next Screen where you want to have "Select All Devices" and then next

    $fastboot5.jpeg

    Now click Have Disk


    $fastboot6.jpeg

    Click Browse

    $fastboot7.jpeg

    Find the files from LeTools you installed and Select LeDrivers and click Open

    $fastboot9.jpeg

    Windows should now have this next box filled in as below Click open

    $fastboot10.jpeg

    Windows brings you back to this window Click OK

    $fastboot11.jpeg

    We finally get to this window where we can select Lenovo Fastboot Device and click Next

    $fastboot12.jpeg


    You will get this error click Yes

    $fastboot14.jpeg

    Holy crap we are finally done 100 mouse clicks later


    $fastboot15.jpeg


    That is finally over and we can now access fastboot.

    Is there a Lenovo's fastboot for Linux? I can adb from Linux (generic adb from android development kit), but fastboot doesn't work at all :(

    Tried Lenovo's fastboot for Windows (from the link provided) under wine but with no success.

    Update:

    gmarkall just pm me a good tip for linux he said.

    Code:
    fastboot -i 0x17ef boot boot.img
    Yaaay!!!

    Unfortunately I do not have a fastboot that works in linux (my preferred OS). I never thought of trying to use wine, currently when I need to I run fastboot I use windows running in VirtualBox.

    Cheers, will try VirtualBox then :)

    Edit: Just saw gmarkall's post in another forum about adding vendor ID; tested flashing a new recovery and it works!

    Code:
    # ~/Downloads $ fastboot -i 0x17ef flash recovery A2109_CWMrecovery-6.0.1.9c.img sending 'recovery' (6340 KB)...
    OKAY [  1.182s]
    writing 'recovery'...
    OKAY [  0.447s]
    finished. total time: 1.629s

    Fastboot works just fine in Linux, probably better than windows version,Just use the fastboot binary that came with your adb binary must be root to use it.
