Step 1: The installation of CyanogenMod 10 on the Nexus 7 is reliant on having a device that has ClockworkMod recovery installed. If your Nexus 7 doesn’t then follow our guide through in the first instance to get the device in the correct state.
Step 2: Download and save the CyanogenMod 10 ROM in a familiar location on your computer.
Step 3: Download and save the Google Apps Package (GAPPS) in a familiar location on your computer as well.
Step 4: Once downloaded, copy the CyanogenMod 10 and GAPPS compressed zipped files into the root folder of the tablet’s SD card and turn the device off. Keep in mind that both the files should not be inside any folder, they should be in clear view for easy access later on.
Step 5: Press and hold down the two volume buttons as well as the power button on the device until the tablet powers on into ClockworkMod Recovery mode.
Step 6: Take a NANDroid backup of the current ROM. Select Backup and Restore before selecting Backup. When the process has completed, navigate back to the initial recovery menu view.
Step 7: Select the Install zip from SD Card option before selecting the Choose zip from SD card option again and navigate to the CyanogenMod 10 file which was copied in step 4. Select Yes on the following screen.
Step 8: Follow the exact same process for the GAPPS file that was also uploaded to the SD card. Back at the main menu, select the Reboot System Now option to complete the process.
