So I'm onto my next hurdle!
The firmware seems to have wrote and now onto 'linkstation booting, please wait..' but the bar got to the end and I got an error stating no response from linkstation after 1200 seconds, try again? plus a red (2 long 5 short) flashing power icon on the device?
I tried a reboot but its back to 2 red plus 5 short flashes?
It did say unable to read some img files before writing firmware but I did just copy everything to make sure I didn't miss anything so assumed it was this.
Thanks
