It can go on either the internal or external sd card (you can put it in a folder if you want).Connect your tablet to your PC. On your PC, open a command prompt window (or terminal for Linux).
Reboot into the bootloader by typing. Code: fastboot -i 0x17ef reboot Immediately start tapping Volume Up until the tablet's screen says 'Booting Android Recovery'.If you didn't press Volume Up quickly enough, it will boot into Android and overwrite CWM recovery, so you'll have to go back to fastboot and reflash.If you did it right, CWM recovery should start. In CWM recovery, you use Volume Up and Volume Down to move the highlight up and down, and the Power button to select options.If you need to root:.

Now navigate to your Superuser-3.1.3-signed-arm.zip and select it. Choose 'Yes Install Superuser-3.1.3-signed-arm.zip'Go back to the main menu and choose 'reboot system now' to restart android. You should now be rooted.To test it out, when the A2109 finished booting, try this at the command prompt. Code: adb shellsuIf you've rooted successfully, the prompt should change from a $ to a # (meaning you have root access).Type 'exit' twice at the command prompt to leave the adb shell.If you are running the stock firmware, each time you boot into Android it will overwrite ClockworkMod recovery with the stock recovery.

Hi mcl630,How are you?I struggling with understanding the method and the 'basic of the basis'.This is the ROM (your rom!!!) that i have currently:Android version: 4.0.4.Kernel version: 3.1.10Build-svr-a@build-svr-a#1SMP PREEMPT Thu Oct 18Build number: MCL0103ILHardware info: 0.SS16.I pay'd to someone to flash this mod on my Lenovo IdeaTab A2109.i really want to know doing this by myself.I would like to ask you few questions regarding youe ROM. Hope that your answers will help me complete this task:1) If i already have a custom rom installed on my IdeaTab - do i have to do the bootloader unlocking?2) If i have the ICS rom - which from the two img's i need to use? 6.0.1.9 c.img OR 6.0.1.9 d.img???3) The Superuser-3.1.3-arm-signed.zip combine the ROM & ROOT? If do, i just need to flash it and it install the ROM and make the ROOT too at the same time?If not.where is the ROM?I would appreciate your help so much!I realy want to learn how to do it.All best! Click to expand.Seeing that you're running the MCL ROM, I know that you've got the bootloader unlocked, a new recovery image (e.g. Clockworkmod) flashed, and root access through Superuser (I believe this is necessary).
According to your info, you have the ROM already installed. Do yourself a favor - push power and volume up at the same time, when your tablet is off, for five seconds or so. You'll see which version of clockworkmod (cwm) you are running. Hopefully it is 6.0.1.9c.
You can easily reboot from that menu.
