QRCodeChimp is beginner-friendly and lets you create a Google QR code in a few easy steps. You can create a QR code in less than 30 seconds without any tech skills or experience. This App provides a dead simple way to generate QR-Codes from URLs, Text Messages, Phone Numbers, Free Text or Contacts . It also allows to scan/read QR Codes if a webcam is available. EBay users ready to spend at least $150 should also add the Google Home Mini in either Chalk of Charcoal to their cart, and apply the “PFREEMINI” code at checkout. Apart from making this powerful voice assistant do a host of things for you, you can also have some fun to pass time and amuse yourself.
The Google Home Mini PCB + Interposer Board can be connected to the NandBug Main Board. The Interposer board, soldered on the Google Home Mini PCB, ready to be used. Of course, using 2.54mm connectors may cause signal integrity issues when dealing with high speed signals. However, looking at the Flash datasheet, it appears the maximum speed was not that fast, and I chose to take the risk. Desoldering and soldering it back is easier said than done, especially considering I'll likely have to do it multiple times. This path may sound like the easiest way to go to achieve code execution, but an important challenge will first need to be addressed.
Be sure to pick the location that matches your shipping address.
This push button is not accessible without cracking the case open. Pushing it at boot time will force the bootloader to boot from the USB port of the device. However, only signed code can theoretically be executed. Please note that, for successful code generation your device clock need to be in correct time and date and also set to correct time zone.
They can scan your Google QR code using an iOS or Android device of their choice. If you create a dynamic QR code, you can edit it without reprinting and also track its scans. But in the case of a static QR code, you can neither edit it without reprinting nor track its scans. A Google QR code allows you to share URLs of Google services, like Docs, Sheets, Slides, etc. Upon scanning, users get redirected to the linked URL in their default browser app. If you want to be able to update it later or use scan tracking, create a Dynamic QR Code.

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.

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. Playing with the bchlib Python library somewhat confirmed this hypothesis.
Can I edit the URL of a Google QR code?
This script is an easy way to find new gift card codes without the hassle of surveys or risk of viruses from downloading a code-gen program. If your Smart TV has the Google Assistant built-in or you have a Google Home Nest or Home Mini, you can control it easily using voice commands. Below is a list of Google Assistant commands that you can use. I have written a dedicated article on describing all Smart TV voice commands including Bixby and Alexa.

Give your Google QR code a compelling look to get more scans. Use unique shapes, colors, and other customization features to decorate your QR code. We will keep an eye on the promotional page going live tomorrow and update this article should we figure out what the limitations actually are. Most applications of Blockly require the user's program to be translated into a programming language.

Please note the Kernel version, sources, initramfs and init.rc file will be useful in the second part of this series of article. Here, the Linux Kernel command line contains the mtdparts configuration variable. This leaks both the names and sizes of all flash partitions. It was now time to actually have a look at the content of the NAND Flash dump. It appears that for each page, the OOB section is filled with a 90 bytes chunk of data.

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.
Generate a list of blocks to erase and pages to program. This step can optionally be skipped if a LAST_DUMP file is provided. Receive the NAND Flash data and compare it to the content of filename. To generate the needed SPI and GPIO signals, the FT2232H is used in MPSSE Mode. Detailed documentation about this mode can be downloaded from here. This bitstream implements a simple FSM that will read all pages of the NAND Flash one by one and stream them to the FT2232H using the Sync FIFO Mode.
The Google Home Mini is protected by some kind of secure boot. While extremely informative, the attack described by the presentation cannot be used against my own device anymore. To conclude, at first sight, the hardware looks rather annoying to work with and doesn't appear to be very talkative.
In this mode, the FPGA will directly connect all the NAND Flash signals between the Google Home circuit and the NAND Flash. Here again, the FPGA is directly clocked by the 60MHz signal generated by the FT2232H when it's used in this mode. The FPGA is directly clocked by the 60MHz signal generated by the FT2232H when it's used in this mode. That's why, for this project, I chose to rely on nMigen. The very same HDL concepts do of course apply, but can be expressed with the syntax a convenience offered by Python. These evenly spaced and sized solder balls will help greatly when it comes to solder the Interposer to the Google Home PCB.
Using these two modes required a special configuration to be burnt to the EEPROM of the FT2232H. The procedure I used to program the correct configuration to the EEPROM is the following. For unidirectional signals, this connection can be achieved directly. However, for the bidirectional signals of the data bus, some arbitration is needed.
