I think you need to get the kernel source tree from : git clone https://android.googlesource.com/kernel/tegra
That tilapia directory and that kernel file you are looking for gets created by applying the n7-3g product files to the aosp build: http://source.android.com/source/building-devices.html WRT gettting the correct sha1 for the n7 kernel version to build I like useing the about device UI on the production image. FWIW my N7-3g today says's : 05b777c tegra.git$ git log 05b777c commit 05b777c19883248ea341945a243ddb64859cd3e7 Author: tryout_chen <tryout_c...@asus.com> Date: Thu Nov 15 14:32:21 2012 +0800 Proximity: Enable sensor by it's previous RIL setting when device resume fro Change-Id: Id5b0bfaa79d62e5c41fa704470cf82bf7a0fefac On Fri, May 17, 2013 at 4:15 AM, vsd <veern...@gmail.com> wrote: > Hi, > > I am trying to build kernel for Nexus 7 3G.
