Stuck on firmware 2020.08.04.1602 and in „activation“-loop

[brougs78]

Hi!

I use a CPLAY2air adapter in a KIA Ceed.
I have updated the adpater several month ago and since then after connecting to the car I get a screen to activate the dongle (see screenshot). If I do so (connect to 192.168.50.2 via the mobile phone) the screen changes to show me „Active Success“ and I have to reboot the dongle. After that the Activaton-Screen appears again.

I downgraded to the version 2020.08.04.1602 via the web interface but now I am stuck with this firmware version.
Trying to update via the web interface I only get the message, that the firmware is current.
I also tried via USB stick (tried several versions and naming conventions, several sticks and formating on Mac and Linux) but if I connect the dongle to power (not in the car) I get the solid red LED. If I then attach the USB stick nothing happens … I am not even sure what should happen (flashing red light?).

Is there a way to somehow force the firmware update?
Any ideas.

Thank you very much.

Kind regards,
Andreas

Hello,

I'm currently working on this issue with my 2 recovered Carlinkit devices.

Try to update to last custom firmware by USB first.

Carlinkit can disable brands or even disable your device entirely because they are the ones sending the content of /etc/uuid_sign from their servers which is linked to your device UUID.

That's the part where the activation is broken / disabled for your device, the UUID is returned back instead of the Base64 encoded activation string to put in /etc/uuid_sign, that's why you get an activation success message but you are blocked in a forever loop.

Hi Ludwig!

Thanks for the feedback. I tried updating with the latest custom firmware and it worked immediately … very cool.
But unfortunately I am still in the „forever loop“.

Is there something CPLAY2air can do on their end?

Otherwise I will have to wait if you can hack the signing process … do you see a chance?

Hi Didi!

Thanks for the feedback. This really does break the loop … kind of.
Any Idea what I have to enter here?
