hard reset failed, and now jamin will not power on

---

I tried to do a hard reset and the black screen came up and when i pressed the green button it tried to format the jamin but then came up with format failed
I then managed to get the device in bootloader mode by camera + reset
then let go of reset and press power once and that got me in bootloader mode, I then tried to install the new rom again and went to 86% and said error [326] This NBF can not be used with your PDA phone. Please check your NBF file. I than took the battery out of the imate device and when put it back in the phone wont even load of anymore its just black and dead. I know it isn't the battery because before I tried the hard reset I charged up the battery to full and i know there is definately nothing on the screen its black and when trying to plug it in via usb can not estqablish connection no more. I feel that this was a hardware issue from the start and is there anything else which i coulld try to prove otherwise? or do i need to send back to service centre? all help much appreciated
