This action is performed on the client side by Blockly. To start the app after installing, open a new tab in Chrome; In the new tab pane you will see an new Icon. We guide our loyal readers to some of the best products, latest trends, and most engaging stories with non-stop coverage, available across all major news platforms. The deal is too good to pass up if you’re an eBay regular, as you’re practically scoring a free Home Mini to add to your home. If you were looking to buy more Minis for other rooms, then this deal is perfect, as you get to save $49, which is the speaker’s usual retail price.

We have compiled a huge list of Google Home Mini and Nest commands. Google even has a dedicated website to help you explore all the capabilities of Google Assistant commands on Android and Google Home devices. Whatever Google Assistant command you use, you must start it with either “OK Google” or “Hey Google”.
How does a Google QR Code work?
The content and structure of the NAND Flash will need to be understood. It's the most direct way of achieving code execution on the platform. My goal will be to modify the NAND flash content until I can execute my own code. Finally, it's important to note that the main CPU comes without public documentation.
This board breaks out the NAND Flash signals to a tiny connector. In 2014, fail0verflow was able to root Chromecast devices with a vulnerability affecting the bootloader. A buffer overflow vulnerability triggered thanks to a special USB peripheral led to a full secure boot bypass.
Installing NandBug on the Google Home Mini
In this mode, the FPGA and the FT2232H communicates by using a parallel bus synchronized by a 60Mhz clock. The entire content of the 256MB NAND can be dumped in less than a minute. The 60MHz clock is generated by the FT2232H and clock the entire FPGA. The Interposer Board that's soldered to the Google Home Mini PCB, right at the NAND Flash location.
This script will simply generate the Passthrough bitstream and upload it to the FPGA. Communicating with the configured FPGA to receive data from the NAND Flash or orchestrate programming operations. Uploading these bitstreams to the FPGA using the SPI Slave Mode programming procedure.
Be sure to pick the location that matches your shipping address.
This bitstream will generate a FSM that's able to program pages. The pages addresses and data are received from the FT2232H using the Sync FIFO Mode. This bitstream will generate a FSM that's able to erase blocks. The addresses to erase are received from the FT2232H using the Sync FIFO Mode.
The first thing to note is that the way the data is written to a NAND Flash is somewhat special. Each page contains data and a special section called OOB, the out-of-bound section. More importantly, the Google Home Mini can still boot without problems despite all the heavy surgery it received.
The NandBug Main Board
What's left is to research vulnerabilities on the WiFi/BLE module of the device or to modify the firmware stored in the NAND Flash of the device. It's reducing the likelihood I can still discover something to exploit in it to bypass the secure boot on a Google Home Mini. The hardware and software of the Google Home Mini is very close to what is embedded into Google Chromecast devices. Hence, it's interesting to have a look at what have been discovered against this product. As you might expect, I'm not the only one who has been studying the Google Home devices. Here is a quick summary of what others have discovered at the time of writing of this article.
To read QR codes with your smartphone, you need an appropriate software installed on your phone. For Android-based devices, you can use Barcode Scanner for example. On iOS-Devices like iPhones, there are also QR Code readers available on the AppStore, for Example i-nigma.
As the range of smart devices has been expanding so does the variety of tasks that can be performed with voice commands. The list of things you can do with Google Assistant is so huge that one might not remember them all. From Android, iOS, and Smart TVs to dedicated smart speakers and display devices, Google’s AI-powered voice assistant is everywhere. Google Assistant is the smartest way to control Wi-Fi-connected smart devices and appliances.
Apart from being an interesting challenge, running arbitrary code on the Google Home could be interesting for several reasons. Finally, it may be a mandatory step if one's goal is to dump the very low-level bootROM code of the main processor. Apart from attempting to run my own code of the Google Home, I guess this solution could also be used to keep track of all firmware updates performed by Google. Indeed, it's possible to let the device run normally for an extended period of time while dumping the entire flash content from time to time. The bulk uploading feature lets you create multiple QR codes at once by uploading an Excel file with QR code data. It saves time, as you don't need to create QR codes individually.
This source code will be extremely useful in the second article of this series. Just start with “Hey Google” to get answers from your Google Assistant, tackle your day, enjoy music or TV shows, and control your compatible smart home devices. And with Voice Match, the Assistant can tell your voice from others—up to six people can get personal assistance on each device.
The length of the ECC data we measured thanks to the graphical visualization could match a BCH-48 algorithm. Going one step further, it's possible to grep for interesting strings in the binary dump. The width of the image is fixed to 2176 pixels, matching the size of a page. Hence, each line of the image corresponds to a single page.
