Requirements:
1. You must have the sdk (ADT Bundle for Win) installed on your Pc and you are able to access, and use adb and fastboot.
NOTE: Notice the install location. This defaults to C:\Users\<user name>\AppData\Local\Android\android-sdk the platform tools (adb, fastboot) and usb drivers will be downloaded to this location. This will be referred to from here on as your sdk directory
But in case you haven't install all SDK, you can use only fastboot by the easy way.(Go here if you want to use the easy way to fastboot)
2. You must have ticked USB Debugging mode in your Nexus 7 3G
3 You must download and install - USB DRIVERS r_06 for Windows 7 & 8
4. Download one of both root-tool
CF- Auto-Root by Chainfire - Download link for Version Tilapia - Nakasig
or the Superboot r4 by Paul O’Brien - Actually I'm not sure if Superboot is functionnal for version 4.2.2 - I tested with my Grouper v4.2.2 and I stayed in Google screen with bootloop.
5. Download your recovery special for your Tilapia - Nakasig
CWM (Touch version or not)
TWRP - latest versions
ClockworkMod - Google Nexus 7 (GSM) - Superuser (fixed) for Android 4.2.
and rename your select with the name of the recovery image you chose to download.
6. The factory image for the Nexus 7 3G => 4.2.2 (JDQ39) - nakasig-jdq39-factory-0798439d.tgz - md5: ee8db1ed6ff1c007fe12136d4bc65cd8- size: 279.9MB - The Version Zip if you prefer
AND DON'T FORGET THAN IT'S BETTER FOR YOUR SPECIAL N7 3G+
TO USE THE SPECIAL RECOVERIES "TILAPIA - NAKASIG"
and NOT "GROUPER" WHICH ARE DIFFERENTS
