You have seen that it’s not at all complicated to install the latest OTA update on your Nexus 7 LTE in order to enjoy Android 6.0.1 Marshmallow. Anyway, if you want a clean Marshmallow installation, then I have only one advice for you: you should choose the Android 6.0.1 factory image installation procedure. All Nexus devices, including the LTE model of the Google Nexus 7 are supposed to receive fast Android updates straight from Google, but this is the best solution if you truly don’t like waiting.
Just like any other Android software update, this is nothing else than a gradual roll out, so it might take a few weeks until it becomes available for everyone. I remind you that as soon as the Android 6.0.1 M update becomes available to your device you should be able to see a system update message in the notifications bar.
Tap on it and follow the on-screen instructions. If there is no system update notification and check for the update manually under Settings > About phone > System updates > Check for update. If once again there’s nothing to find, then you can flash the Factory Image for Android 6.0.1 on your Nexus 7 LTE with no hesitation.
Do you know that this Marshmallow update operation will perform a clean firmware installation, so all your data will be lost? My advice is to back up everything with the help of this tutorial on How to Backup Android Data Without Root or else don’t blame me for your mistake. Then, you must also Open Settings> Developer options and enable USB Debugging on your device. To enable developer options on your Nexus 7, tap the Build Number multiple times in About Phone.
Then, you must set up ADB and Fastboot on your computer, so install the full Android SDK package from Google through this link. And do not forget that you have to install the latest Nexus USB Drivers on your computer too or else connecting them at a later time will become impossible.
