PUMPKIN CAR STEREO SUPPORT CENTER

I have a newly acquired ND294B with android 8.0.0 although it was supposed to have 8.1. The stereo gets into an update loop every time the Google services library updates. I have factory reset several times and have also tried the kupdate.zip file as a solution found in this forum. The result however was still the same, after updating Google play services and shutting the stereo off it will loop on the next usage. Is there a solution to this?

Hi, about this issue, you can contact the pumpkin customer service or the seller where you bought the unit.
I suggest you attach these information:
Your Amazon order ID&order date:
The details of the issue(when did it happen&what happened&what did you try to do to fix it);
Attachments(It couldn't be better if you would provide us with pictures or video link);
It will help us understand the issue and provide you right solution.
Your car model and made years;
You phone model and system version(if it is regarded);
The rest of the supplement.
Regards
