I suppose TAC is something like a customer support, no, haven’t raised it them. However, I raise it to the dealer where I bought the box. They are escalating to quintum (according from them) and its been 2 weeks now, still haven’t heard anything from them. Have you raised it to TAC?
Are you still having this problem? Quintum made another patch last week for reverse battery. If you email me at tarrant222@yahoo.com I’ll send you a link on where to download it
