Unknown tablet without Android
The reason it is bootlooping is probably because cyanogenmod was installed and it isn't for that device. 

There should be serial/model number on the back of the device. This is a requirement (AFAIK) by the FCC. 


  The certification mark is a stand-alone logo (as shown above) for the part 18 class of devices while, for the part 15 class, along with the logo, the label should display other data viz, the trade name of the product, the model number, and information whether the device was tested after assembling, or assembled from tested components.


You should be able to use that to figure out what device it is. Then you can see if you can find a version of android for it from that.
