GX440 Not Completing Boot up

Hello,

We have a few GX440’s. I have been updating a few of them to the latest firmware. I have ran into one that is causing some problems though. It doesnt want to give me any internet activity or anything. I have updated 6 already with no issues. I connected this device like all the others. I have tried a different antenna and no luck. It starts the initial boot up and then the power LED stays solid green with no other lights doing anything. Then it reboots itself after a 1-3 minutes and repeats the process.
Thanks for the help!
