failed update

Hello, Please help. I film for a local high school team and 2 days ago when filming a message appeared "firmware update needed". so, I hit update and because I wasnt connected through wifi update failed. Immediately after, I went to film and remote would not respond. Took it home and googled...

So i've tried updating the firmwear but nothing happens, I dont get anything from my phone saying to update and I have no status indication for the aircraft. when I try doing a force update it starts but than fails all the time. I've also tried relinking the remote to the phantom and it fails...
