Hello,
if you have got non-working Multibox cables you must talk about this with Multibox support. We can't help you with other box support, so, please, contact to Multibox and talk with their support.
As about Infinity-Box cables and pinouts for Chinese models:
Due to a lot of different models with
the same name but absolutely different hardware,
bottom connectors and different pinouts we recommend you to make detailed description of model,
attach phone photo, phone bottom connector photo and information about Gnd and Charge pins on phone bottom connector.
After you have this information prepared, please, check the next detailed description how to get pinout for your model:
use "Cable Selector":
