You will be stuck in fastboot if you have failed to flash an img file. You will have to boot a boot.img file using fastboot then download the last update to get your tablet back to normal.
Download the following file onto your computer...
Then unzip on the computer. You will see a file named "boot.img". Make sure your tablet is connected to the computer and you have the fastboot binary. Then run the following command in the directory you just unzipped the file
fastboot boot boot.img
This will allow you to boot up your tablet but the bootloader will STILL be stuck in fastboot. Therefore you will have to update your system. Download the same file above into the Download directory of your tablet. Rename it to update.zip. Dowload the following XML file...
and rename it to update.xml (NOTE: the system file manager won't let you change the extension so just rename to "update". Power off the tablet. Then hold down the Volume + key and hold down power button until it comes on. That will boot the system into recovery and install the update. In a few minutes you will be restored and your tablet will work normally. NOTE: YOU MAY LOSE YOUR DATA and may have to reinstall your apps.
If your boot partition isn't a mess like mine was, you may be able to just flash the system partition from the above zip file by using...
fastboot flash system system.img
The key is that a fastboot flash must be successful in order for your device to boot normally.

My k1 is also stuck in fastboot mode. I managed to boot the tablet but after downloading update.zip and restarting it won't take the update. I tried holding volume+ power and it just goes back to the fastboot screen. The tablet will not let me use the fastboot command flash system system.img. After imputing this command into fastboot it displays verify_sha: not mach on the tablet screen. I think the digital signature may be wrong on the rom.
Anyone have an idea what I am doing wrong!

How did you go into fastboot mode? I am not able to figure out. I have Lenovo A1000-T
adb reboot bootloader
adb reboot fastboot
adb reboot recovery opens it in recovery mode.
Niether of them worked. I have installed Lenovo Le Tools also.
Also tried to open it by pressing -
Vol down + Power (opens factory mode)
Vol up + Power (opens recovery mode)

Thanks for replying. What is 'Preloader' mode? I am only aware of a 'Recovery Mode' and 'Factory Mode'. I am trying to flash ubuntu mobile on my Lenovo A1000. Can you please suggest me how to do it, if it doesn't have "Fastboot Mode"?

Yes i know that. But its worth trying. I am going to install ubuntu mobile which is ubuntu's version for touch devices. They must have twaeked firmware according to these android devices. But i have one more thing to ask - They want bootloader to be unlocked and then give a command to flash it there. But i am not sure about how do go about it if i am gonna install in preloader mode using SP flash tool? Here is the installation link for ubuntu mobile
Is there any alternative (like commandline) of SP tools for linux operation system if i am not having windows system?
