    Some months ago, I bricked a Lenovo A2109. I was tired, frustrated and managed to screw things up pretty good.

    I boxed the tablet for another day. A year later, it's another day, and I hope to re-activate this tablet.

    Here's what I've attempted today:

    Power on, obtain the black & white Lenovo icon. After 15 seconds or so, it seems to reboot, and we go into an endless loop at bootstrap.

    Boot to recovery presents: "CWM-based Recovery v6.0.2.8"

    If I perform "wipe data/facory reset" the log states:
    Wiping data...
    Formatting /data...
    Formatting /cache...
    Formatting /sd-ext...
    Formatting /sdcard/ .android_secure...
    Data wipe complete.

    If I then attempt to reboot system, I obtain the bootstrap endless loop.

    If I use Recovery to install zip from SD card: (A2109A_MCL0201.zip), I obtain:

    Finding update package...
    Opening update package...
    Installing update...
    Install from sdcard complete.

    Reboot system, obtain:

    White Lenovo logo on screen (endless loop)

    If I attempt a sideload recovery, such as:
    On computer: "adb sideload a2109_stockrecovery.img"

    I obtain:
    daemon started successfully
    sending: 'a2109_stockrecovery.img' 100%

    Then on tablet I obtain:
    Opening update package...
    E:Can't open /tmp/update.zip
    Installation aborted.


    From this trail, is someone able to suggest how I might reload an operating system?

    Lenovo LeTools and Lenovo Smart Assistant both report lack of connectivity. Both say "enable debug mode," which of course I'm unable to do since I can't boot into Android.

    Suggestions appreciated, and I think your for your time in advance!

    How about going into the fastboot mode, then trying to flash new recovery and the ROM again? This thread [HowTo] Unlocking the Bootloader (Windows) and this one [ROM][4.4.4] Cyanogenmod-11 for Lenovo A2109 (20151001)
