Thanks, ***** ***** only one cause left for this
It is the internal memory that has faulted, this is the reason why you cannot unlock or even restore it.
A corrupted firmware can cause this. But we have ruled this out by trying to reinstall it. The fact that we cannot get to the recovery window, confirms it is the memory that shorts out, and causes the device to fault.
I am really sorry about this and you are going to have to return the phone to have it 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.
