Car stuck on Software Update

[davemarco]

Now that I think about it, since you're rooted, USB Debugging should be enabled. If you hook up your laptop to the head unit via the car's USB port, maybe you can use the command prompt on your laptop to issue ADB commands? If so, then you should be able to reboot the head unit and get it to load the OS like normal.

I can reboot it, at least by selecting the option in recovery. The back and menu button are up/down and home selects. Pulled the fuse even though I know that won't do anything. I mean if you get stuck like this on a phone pulling the battery never helped me. I've rooted all my Android phones since my first one (forget what it was but was around the time of the HTC hero because I remember my wife had that) and I rooted my S2, my Optimus S and G, Evo, etc and only problems I couldn't solve was the Optimus G forgot who it was and I had never run the script to back up that info since it was a common thing happening to those phones and I didn't pay enough attention to the forums, missed that part and just kept flashing away. That and eventually my S2 bricked but I think it was hardware because the error screen was an Android bot pointing at a chip with an exclamation point... Hope I can get this solved but like I said the trip is soon and my time really isn't available for dealing with this...

Ok, so I don't know if it just didn't work for the OP or if he didn't take the advice. Maybe just didn't wait long enough but I pulled the fuse and left it out for 2 drive cycles over the span of maybe 1-1.5 hrs. got home, shut car off, reinserted fuse in, got in and turned car on and got the H and thought it stuck there but it then went to the pop up about locating gps signal, then the drivers responsibility pop up then BOOM, WORKS!!!!

This is what worked for me: When prompted with the system update screen, select the "update from adb" option and let it sit for a few minutes and it will restart bringing you to the "H" symbol.

Took the radio fuse out for a little over 10 min then replaced. It worked! No dealer involved, thanks!

Find the radio fuse and pull it for 10min

Worked for me! (More like 1/2 hour but still, it worked) - Pull fuse #19 - a 15A fuse for Audio, in the engine compartment fuse box.

This just happened to me on a car I've had less than a week (2018 sport touring).

The bluetooth was skipping so I rebooted the radio (power for a few second, reboot) and then it came up with the software update screen.

Update over ADB just sent it to a blank screen for 15 minutes. I pulled the fuse and waited 10 minutes and that did the trick. (I was mad for a minute when it was asking for a code after booting, but turning the car off and back on made that screen go away)

Ugh dealing with this now.....

Trying the adb wait.....

Turned off engine. Pulled fuse, counted to 20. Replaced fuse. Started car. Saw honda logo for a minute or three. Back to normal.

Phew

Dumb question. I remove the fuse with the car off. The. It stays off for the 10 minutes or should I run the car? Or does it not matter

 

[Justintime37]

So follow up. I turned off the car for 20 minutes. Fuse in and it booted fine. Crazy though

Turn the car off, pull the fuse and walk away. I kept the fuse out for 30 min just to make sure. Worked just fine after that! Good luck!

I restarted a few times, but it didn't work.
Just waiting for 15min in traffic patiently with the "software update" screen and it started correctly by itself.

Same problem here.
Let the car run without toching the screen for 30 minutes. The system will go back to the "normal" screen.
