As you can see, the CyanogenMod community has released the new CM 13 ROM for many Android devices and your Nexus 7 Wi-Fi is added to the list as well. I can assure you of the fact that the ROM is official and bug free, so there is nothing stopping you from enjoying it.
However, if you don’t know what to do, you can follow the instructions listed in this post in order to learn how to successfully flash the brand new custom ROM without bricking your device. For that, you must remember that the listed custom ROM is compatible with the Nexus 7 2013 variant only, so do not try it on any other device or variant.
Then, make sure you have the most recent TWRP recovery installed on your tablet, as well as its drivers installed on your PC in order to transfer the ROM and Google apps to the storage.
Before you proceed, you must also backup all your data. This process will wipe all the data from your device except for the internal storage. In such a case, you can only imagine that a full backup backup is recommended. My advice is to backup all your internal storage files just in case a step of the procedure goes wrong and don’t hesitate to use one of these tutorials: How to Backup and Restore IMEI / NVRAM Data on Android Devices or How to Backup Android Data Without Root.
You must also make sure that the battery is charged at minimum 60% and as a reminder, the warranty may be void if you choose to apply these steps. You might use the guide on How to Restore the Warranty on your Android device, but even if you do that, understand that I won’t be liable for any damage to your device, I won’t be held responsible if you brick or damage your device. That’s on you!
