How to resolve boot loop problem on android PumpKinx 10.1" tablet
I Believe you are using some non branded (fake or Chinese) device and unfortunately the device don't get updated officially. But you can do a couple of things with it first restore and enjoy the previous version, or contact the manufacturers of the device they will send you, your desired ROM, it will take a couple of working days. I had this issue back in the day, all I did to restore it and hard reset. After two days I got an email, but they wanted me to pay for sending me the new ROM.
