I can see available stock in some stores but please do call up to confirm. Voice Match requires additional setup and enrolment, and supports up to six users. When using Voice Match, keep in mind that a voice similar to yours, or a recording of your voice, could result in Google incorrectly recognizing someone else as you.

The FT2232H in SPI and Sync FIFO Mode
The FPGA is directly clocked by the 60MHz signal generated by the FT2232H when it's used in this mode. This section gives some information concerning the software and gateware architecture behind NandBug. It's not absolutely necessary to read this section to understand the rest of the article. These evenly spaced and sized solder balls will help greatly when it comes to solder the Interposer to the Google Home PCB.
Manually soldering thin wires to the BGA footprint for breaking out the NAND Flash lines could have been risky because of signal integrity issues. It wouldn't have been a very clean and, more importantly, reliable solution. Repeatedly desoldering and soldering back the NAND Flash would have been annoying and could have caused damage to to the PCB.
Building & Hardware
Control it all with just a tap or two – and get to the good stuff faster. The Feed tab highlights important events in your home in one place. Here, you’ll also find ways to get more out of your devices and improve your home setup. But, as the second part of this article will demonstrate, it remains possible. 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.
This leaks both the names and sizes of all flash partitions. Using strings and grep against the firmware dump can quickly reveal interesting bits of information. I guess this nibbles swapping weirdness is caused by the way the low-level hardware BCH engine is actually working. Swap another time the nibbles of the computed BCH code. Another transformation was applied to the data before or after BCH encoding.

In our case, reading the datasheet of the NAND Flash used by the Google Home, the TC58NVG1S3HBAI6 gives the following details about the internal memory organization. The OOB section of each page is usually used to store Error Correction Code or ECC. This is needed because of how imperfect NAND Flash technology is. Bit flips are very common with these memories, and ECC are an efficient way to address the issue. 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.
Please note the Kernel version, sources, initramfs and init.rc file will be useful in the second part of this series of article. The Linux Kernel version and compilation timestamp can be extracted from strings present in the binary data. Here, the Linux Kernel command line contains the mtdparts configuration variable.
For instance, keeping track of the Google Home Mini firmware releases becomes relatively easy. Further, attempting to run arbitrary code on the device from the NAND Flash becomes possible. One of the very early design goal of NandBug was to be able to monitor the data read and written by the Google Home to the NAND Flash in real time.
A exploit could be needed to bypass the secure boot. 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. 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. Explore our range of smart lighting products and learn how easy it is to automate your lighting. When using Voice Match, keep in mind that a voice similar to yours, or a recording of your voice, could result in Google incorrectly recognising someone else as you.
A few weeks ago we unveiled Google Home Mini, the newest addition to the Google Home family. About the size of a donut, it has all the smarts of the Google Assistant and gives you hands-free help in any room of your house. Starting today, you can grab it online from the Google Store or online or on shelves of Best Buy, Walmart, Target and other stores. Link your other Smart Home appliances, lights, and other Google devices. The built-in security in your Google Account automatically detects and blocks threats before they reach you, so that your personal information is secure. Create Routines that allow you to turn on compatible lights, check the weather, play the news, and more with one simple command.
The connector can finally be hand-soldered to it, using a simple soldering iron. Everything is next melted together with the hot air station. A better video of a similar process applied to a real BGA component can for instance be found here. As it must be soldered like a BGA component, I'll turn it into one by soldering tiny solder balls. A small connector matching the one of the main board. The Interposer Board that's soldered to the Google Home Mini PCB, right at the NAND Flash location.
Set up your Nest Wifi and Google Wifi in minutes using the Google Home app. Run speed tests, set up a guest network, and easily share your Wi-Fi password with family and friends. Use parental controls like Wi-Fi pause to manage online time for the kids.
With the simple push of a button, I am able to control the status quo of said electronic. Apart from being an interesting challenge, running arbitrary code on the Google Home could be interesting for several reasons. Indeed, because the processor of the Google Home Mini comes without any public datasheet, arbitrary code execution can lead to a way better understanding of the system. Finally, it may be a mandatory step if one's goal is to dump the very low-level bootROM code of the main processor.
The NandBug System
As explained before, the SoC of the Google Home Mini comes without any public documentation. Being able to run custom code on it is valuable to understand it better. Things like dumping the BootROM of the system becomes possible. To conclude, at first sight, the hardware looks rather annoying to work with and doesn't appear to be very talkative. A mechanical switch, used to disable and enable the microphones. The main speaker of the Google Home can be plugged to this two pins connector.
