Was your unit totally bricked like mine? As in, no lights at all?


I didn’t see any lights on it but I was stuck couldn’t get it to be seen in the truck and not broadcasting Bluetooth Not sure if it was bricked or acting up. So I used my CarPlay2air that had 3/6/20 on it to show me an update then updated the problematic Dongle to the current firmware at that time using this method.

Understood. Thanks. I'll give it a shot. What could it hurt?! You're da man, Denali!
 
I know 192.168.x.x (like 10.x.x.x) is non-routable on the web, so I assume the iPhone will look through the lightning cable for this IP?

I was home when I did it. I didn’t turn wifi off on the phone.

Just don’t refresh the safari page keep it open till you press the update tab.

So, it is safe to assume when you turned off your truck, the iPhone disconnected from your working adapter in the truck, and then reconnected to your home WiFi, when you went inside, no?

Got it, on the no-refresh.

I’d have to say yes. It probably connected to my home wifi.
 
Try this on your bricked unit.

1. With your truck on and wireless CarPlay running search 192.168.50.2 it should show you the firmware update to 8-4-20 on your phone. Keep this page open.

2. Connect the bricked unit to the wall power brick.

3. Connect a iPhone/iPad lightning cord to the bricked unit.

4. Connect your phone to the lightning cord.

5. Now press the update firmware tab on safari on your iPhone screen and let it go through the process.

6. This worked for me on my Carlinkit usb-c once when I couldn’t get it to do anything.
Thanks, I have two bricked USB-c devices both show no lights. I don’t quite understand how it will find 192.168.50.2 if it cannot even be seen via BT let alone Wi-Fi. The 192.168.50.2 address will only be accessed if you are connected via BT / Wifi to the dongle, if we can’t get there it won’t load the page. Since it’s essentially trying to access that page over 4G or your home Wi-Fi. Unless you’re saying you need a third perfectly working unit to get to that page, and then go inside with the bricked unit, plug the bricked unit into the power supply, then use your USB-A to lightning cable to piggy back the iPhone to the device and then force it download (via home Wi-Fi or 4G).

So 7-29-20 has been working great on my Carlinkit USC-c I feel better then 3-6-20 as it also now auto connects if it disconnects due to Radio frequency interference. No audio issues after a week of use.

I actually updated my CarPlay2air from 3-6-20 to 8-4-20 OTA to test it. It has also been working great I’ve done a couple 2 hour drives with out any issues on my GMC Sierra.

Thank you for confirming. I went back to the link for 7.29.2020 firmware you posted a week ago but it was dead, any chance you have a link to where I can download and flash?

Yes I will upload it in the morning. I’m not around my Macbook right now.
 
I have also done OTA on my USB-C from 7.29 to 8.04 without any problems. Music Track changes feels much faster on 8.04 with iOS14.

Thanks, track changes faster with 8.04 compared to 7.29 on iOS14?

Thanks, I think I am going to give it a go.

Well, again, I'll be a blue-nosed gopher. This actually worked! I have a resurrected CPlay2Air unit now!

I did exactly as Denali outlined. After plugging into the lightning cable, I clicked "Update", it slowly worked its way from 0% to 100%, then gave me a spinning ring with the message "Upgrading, please be patient, this could take a while". It then reported, "Upgrade Complete". So I unplugged everything, took it back out to the truck and BAM, it came back to life! Head-unit saw it, and I was able to join it with my phone. All good!

Now here is the weird thing: After joining the adapter's WiFi manually in the truck, I navigated to 192.168.50.2 and it reported the firmware as 7.17 (which is what was on the adapter when I bricked it)! So I disconnected, and reconnected via Bluetooth (which then handed off to WiFi) and re-navigated to 192.168.50.2 and it is now offering to "Discover a new version..." to 2020.08.04.xxxx. I was too scaredy-cat to try another OTA update, so I shut down and have brought everything in the house to do a manual USB update to 2020.08.04 and see if that works.

So, to sum up, I am not totally sure exactly HOW this works, but it certainly does. I had a totally unresponsive, completely dead / bricked, CPlay2Air adapter, that would show absolutely ZERO lights, in the truck or when plugged into a power adapter, that now is working again. And while I'll be the first to admit that I was very skeptical about this technique, given my years of experience with networking and routing, I am extremely happy to report that it works! Or at least it did for my bricked unit. YMMV.

@2018 Denali, I don't know what kinda cereal you eat for breakfast, but it must be the "breakfast of champions", because once again, you my friend, "are da freakin' man"!
 
Do you think that this procedere also works with an adapter that shows the blue light only?
