5. Go to settings, Developer options and select Advanced reboot
7. connect your tablet to the pc and save gapps on your sd card. Or download gapps via liink.
8. Go in Recovery via long press of Power, and select "Reboot" then "Recovery"
9. Flash the gapps package that you downloaded in step 1.
Please help to advice, How I can select "install Zip" to install Gapps?
I have flash the CM10.1 rom ([ROM][JB 4.2.2][CM10.1] for Lenovo Ideapad K1 Wifi) for IdeaPad K1 by Nvflash and after reboot I have done as step below from step 5-8 and then go to recovery mode. And I have tried to do for step 9 by tried to select by move "Vol +/-" down to "Install Zip" and then tried select it by press "power" but can't. Because after press "power" the selector will go to first row"reboot system now". Look like I can't do anything because after press "power" it will back to first row "reboot system now" and can't selected.
