Our 9505a
Iridium phone has a well know "invalid battery" fault and we can not charge any
batteries until we fix it.
It has the original firmware and it does not recognise any
battery we put in it. To fix the problem we need to get a hold of a data adaptor or kit so we can connect it to our computer and upgrade the
software in the
phone. (it has the version 1
software, it is now up to version 5)
If someone has a data kit that we can rent or borrow or access somehow, it would be much appreciated as this fault is driving us nuts. We have bought 3 different
batteries only to find none of them will charge in the phone.
