We have a Galaxy Note 4 that we replaced the screen on about 2 months ago. The customer has since abandoned it, so we have claimed the phone. We can reset the phone and wipe the data, but system updates will not work. I'm attempting to use Samsung Kies to update the system software (which is currently on 5.0.1), and it finds the update for the phone. However, when it reboots into ODIN mode (with the Downloading...Do not turn off target!!), it loses the connection to the computer and Samsung Kies fails. I have tried on 2 different computers with 2 different cables. Any suggestions?
