• Packet Capture: First Steps

    The very first step is to capture the wifi direct packets between the Nomad Android app and the Nomad RC. I'll need a device that's unlockable and can obtain root access. I have piles of Samsung devices that are notoriously difficult to root and unlock.

    After some research I realized a used OnePlus 6T can be easily rooted. There were two models created: A6010 made for the Chinese market and A6013 called "International". In reality the international models are all locked to T-Mobile which, again, is known for making it difficult to unlock devices.

    There is a trick that converts the International version into the Chinese version. See, the hardware is identical and only the branding and software capabilities change. So I found a converted 6T on eBay for $115. I will use this as my primary rooted device. (The last rooted device I used was a Samsung Galaxy S3!)

    The new device should be here November 7th, 2023. I have a new install of Lubuntu desktop along with adb tools, android studio, and vscode. I'll use these to start the packet capture process. Once I get the phone unlocked and rooted I will follow this guide on decrypting wifi direct on android.
