[Thinkpad Tablet General] me_is_rushin:
This is my first thread of this type so I am open to any/all suggestions. I noticed there were a lot of users that emerged on various forums during the wait and eventual release of Ice Cream Sandwich from Lenovo. So I decided to start this thread as a guide/FAQ to try and make things simpler. We were all once in a place of confusion regarding Android. I got helped many times along the way so I figured it would be my turn to help out some newbies.

This thread is currently a work in progress as I try to add everything that is deemed important to know. I will try to keep this up to date with everything we currently have available. If something is missing and needs to be added just send me a PM and I will get on it ASAP!

First, a few disclaimers! READ THESE FIRST!

~Anything you do to your tablet is your own fault! Neither myself, nor the developers whose modifications are listed below are in any way at all responsible for what happens!

~There are probably more disclaimers I should add so....

Now that that is out of the way, lets get started!

So you’ve got an Ideapad K1 and have decided to jump ship from the stock Honeycomb experience from Lenovo.

Things you are going to need:

1. The USB cable to connect your tablet to a PC (Yes, you will need a PC)

2. Your battery should be charged to 100%

3. You must have these drivers installed on your PC.

Things you need to do:

Next you need to backup anything you do not wish to lose. When you flash, everything on your tablet will be wiped. This means you will lose any apps/data/music/pictures/etc.

Apps are backed up through your Gmail account and should easily restore once you boot up. Any other data should be copied over to a computer or an external micro-sd card and can be later copied back onto the tablet.

Now you need to decide what you are going to flash. As of 7/31 you only have 3 choices.

There is

1. Stock ICS Lenovo rom which is missing Google Play Store and all Google services (Generally not recommended) Can be found here Stock Lenovo K1 ICS

2. Thanks to developer khanning88 we do have a version of the above rom with an included Play Store (although it has limited functionality) This rom comes in 2 version. Stock and rooted. If you do not know what “rooted” means then I suggest you stick to the stock rom. Both can be found for download in khanning’s thread. Also remember if you want to show him some thanks for his work he has a donation link. Official K1 ICS w/Play Store

Just download whichever Zip update package you believe is best for you and extract the contents into an easily accessible folder.

Assuming you have followed these instructions you are now...

Ready to Flash:

Flashing is relatively simple, but the instructions must be followed carefully to avoid any complications.

First thing is to boot your tablet into APX mode.

To boot into APX mode:

1. Power off

2. Hold down the Vol - and the Vol +

3. While holding the Volume keys down, Power on

4. The display should go black, and both LED's on either side of the home button should light up. This is APX mode.

Now you need to plug the USB cable into your tablet.

Next, you need to go the directory where you extracted the update zip. Find the "flash-windows.bat" file and double click. You should see some text appear on your tablet, this means it is working. Just sit back and wait. Once it has finished it will automatically reboot and you should see Android 4.0 ICS boot up.
