或許你已經注意到了，Nexus 7 3G出廠設定時的tethering（上網功能分享功能）是關閉的。

就我個人而言，若沒有上網分享這個功能，我可是會活不下去的（這也就是我選3G版本的其中一個因素），這功能需要對framework做一個修正的動作才能開啟。 PaulOBrien@MoDaCo 已經在Android 4.2對apktool做了修正。

要開啟這樣的功能需要刷入底下的ZIP檔，目前只有在JOP40D和JOP40C版本才能正常工作。很明顯的，這是用在3G的nexus7上頭，別試著把他用在wifi 版本的nexus 7上。

步驟中並不會備份原始的framework-res.apk，你可以自行備份一個，方便日後恢復時可用，或者刷回出廠時的system image恢復到官方版本。

4.2.1 (JOP40D):

PLEASE USE WITH CAUTION AND ONLY IF YOU KNOW WHAT YOU ARE DOING. I WILL NOT BE RESPONSIBLE FOR BRICKED DEVICES.

You may have noticed that the Nexus 7 3G does not have the tethering options enabled by default.

I couldn't live with that (that was partially the point why I got the 3G version), so have patched the framework to enable those options. Partial credits go to PaulOBrien@MoDaCo who has fixed the apktool for Android 4.2 .

To get it to work just flash the ZIP below. It will only work on the JOP40D and JOP40C releases, and obviously only if you have a 3G device. Please do not try it on the WiFi-only Nexus 7 .

Please note that it doesn't do a backup of the original framework-res.apk, so you can either make one yourself, or you can reflash the factory system image if you want to go back to stock later.
