I couldn’t find much information out there in English so I’m putting this online for anyone who needs it.
I am, of course, not responsible for any damage done to your device.
Information is derived from these sources, primarily copied and clarified from the first:
a. Download ClockModRecovery. The direct link is http://www.megaupload.com/?d=AO4M7NKX (Decompress password is “http://www.droid-style.com”).
b. Decompress the zip file, and you will have these two files (Do not decompress them) “lepad-a1-rooter_signed.zip” and “update.zip” . Save the two zip files into the root folder of MicroSD card.
e. Shutdown the Pad.
f. Turn on the Pad by holding “Power” + “Volume down”, wait until “Lenovo” logo disappears, hold buttons for around 10 seconds, and then release buttons.
g. Press “Power” + “Volume down” again and hold until you see a green Google App installation logo, then release buttons. You will see ClockModRecovery recovery mode.
h. Press and hold “Volume down” until you see “Back Menu Button Enabled” at the bottom.
i. Press “Volume down” to select “install zip from sdcard”, and then press “Power” button to confirm.
j. Press “Volume down” to “choose zip from sdcard”, and then press “Power” button to confirm.
k. Find and choose file “lepad-a1-rooter_signed.zip”, and then press “Power” button to confirm.
j. Find and choose “yes”, and then press “Power” button to confirm.
k. Find and choose “Go Back”, and then press “Power” button to confirm.
l. Find and choose “reboot system now”, and then press “Power” button to confirm.
If you need to install market, download the latest Google Apps package from http://goo-inside.me/gapps/gapps-gb-20110828-signed.zip (29 Aug 2011 version) and repeat the process.
