Do you know for fact that 17ef is the vendor code for the A2109a?
I've been looking everywhere!
It should be sticky'd cuz... damn long night! hehehehe

You can try "udevadm monitor --environment --udev" too, it says:

ID_BUS=usb
ID_MEDIA_PLAYER=1
ID_MODEL=IdeaTabA2109A
ID_MODEL_ENC=IdeaTabA2109A
ID_MODEL_ID=74e6
ID_MTP_DEVICE=1
ID_REVISION=0232
ID_SERIAL=LENOVO_IdeaTabA2109A_FD60******
ID_SERIAL_SHORT=FD60******
ID_USB_INTERFACES=:ffff00:ff4201:
ID_VENDOR=LENOVO
ID_VENDOR_ENC=LENOVO
ID_VENDOR_ID=17ef

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.

Where do I get the fastboot binary for Ubuntu 12.04?

Edit:

I found:

I found:

Sorry, I can't answer that one. I use Windows for adb & fastboot. You might want to try the Lenovo forum.

I have been pointed to adb-fastboot-install - A script to install ADB & Fastboot on Mac OS X and/or Linux - Google Project Hosting in the lenovo forum and I am not sure how to go on.

Earlier I read in this thread:

fastboot -i 0x17ef boot boot.img

But what is "boog.img"?

I flashed a2109a_a411_03_13_121126_ww.zip earlier, which drains my battery.

dmesg | grep -i lenovo

dmesg | grep -i 17ef


lsusb | grep -i lenovo
Bus 001 Device 006: ID 17ef:7542 Lenovo

What is the next step? Thanks!

Boot.img is in the root of the ROM zip. Just open the zip of the ROM you flashed & you'll find it.

If you don't like JB 4.1.1, you can roll back to 4.0.4. Just flash it over. I think it'll wipe your internal storage (sdcard), so make sure to back up what you need.

Thanks, now it says:

fastboot -i 0x17ef boot boot.img
< waiting for device >

Do I have to be root on my Ubuntu box?

It sounds like you are not in fastboot mode. When your tablet loads as fastboot, do you get one line of text or two?

Wait a minute. Why are you trying to flash boot.img?
