It is the internal mainboard that has faulted, this confirms it now.
I am really sorry about this and you are going to have to return the phone to have this replaced. It will be covered by the warranty if this has not expired, and the replacement will be done at no cost to you.
I am really sorry about this, and if you have problems, or would like any additional information or assistance, please do not hesitate to let me know.
