It's been a while since the initial release of the google home hub but no one knows how the firmware really get's flashed using the hidden micro usb port under the rubber bottom surface.

Well, it's very simple, it uses the Amlogic S905D2G chip ( similar to what cheap tv boxes have ) which means it can be simply flashed with a custom rom via the Amlogic Usb burning tool. In order for it to go into flashing mode you need to hold both volume up and down buttons then plugging the power cable whilst also having the micro usb cable is plugged into a computer.

As you can see the connection is successful meaning that this can truly be flashed but...


There is a small catch, google never reveals pre compiled firmware for these devices meaning you would have to compile it. There was recently an update from which there was a high possibility google was transitioning to a different OS called fuchsia while seamlessly leaving the same UI as the original OS was and hopefully still is android.

Once the drivers are installed, The google home hub can be seen as what is above. before driver install, your computer should've detected it as GX-CHIP

Hope this helps with future development on this little platform as I don't see much going on.

Does this apply to other Google Home Speakers, more specifically to the LG WK7 ?

Mine has toasted itself - I suspect it got corrupted doing an update and Google can't help me. They say "It's dead Jim!". Has anyone found a valid ROM that I can flash it with and see if I can resuscitate it? TIA

I see that some of you guys are interested in fixing/modifying your device(s), me included.
So I wondered if you may be interested in creating a Github project to help us out eachother.
I definitely would!

Maybe good to know that after the fuchsia upgrade everything has changed. Holding volume up while powering up gives fastboot mode. Volume down gives recovery mode but I don't know what that does.

I flashed a TWRP build over my recovery and now the recovery is broken... Stupid. Anyone wanna try to tinker with the recovery? Maybe try a port scan. Or try volume up or down while in recovery?

Hello - I also have a bricked google nest hub. I removed the bottom. The micro usb socket is connected to the pc. A cdc device was found. more precisely two of them. I have loaded the armlogic driver, but the device is not recognized in the burning program. I would be very interested if someone could generate a recovery file to repair the device. thx martin

My Google Nest Hub bricked itself. I believe it happened when I powered it off while it was booting up.

I can hold 2 keys and get into Recovery mode, but I just get stuck on the "G" screen when trying to reset the device.

I too have a "CDC-Ethernet" device when I plug the micro USB (hidden underneath) into my computer.

I would love to be able to restore a standard ROM, or even a custom one.

I am trying to fastboot my 1st gen Nest Hub, but it looks like it doesn't.

What I do is to keep pressed VOL+ and then I power up the device.

Is that correct?

I desperately need to fastboot it because it looks like something f up the firmware (factory reset has the same behaviour) and it ends up with a white screen loop crash.

    I was hoping to find a way to flash the original firmware on the first gen hub, but there are no roms available anywhere? :(
