RBK50 decided to stop working, won't factory reset

A couple days ago my Orbi RBK50 decided to stop working correctly. In an attempt to disgnose the problem I powered down the two satellites (RBS50). I also connected directly to my modem (an ATT BGW210 residential gateway device) to verify that it wasn't an internet outtage. I did a reset on the RBK50 and attempted to set the network up again. I tried running the Orbi setup app on my phone and after a few minutes the phone asked to join the Orbi70 wifi network. After tapping Ok, a few seconds later it said it could not join. 

I tried a few more attempts to reset the router and it just kept getting worse after that. Now I couldn't even get it to go from green to amber. At some point I saw red flashes, but not consistent.

I found the 30-30-30 trick and I was able to get the device to flash red. During this time I noticed I was able to ping the router. I've tried TFTPing firmware to the device, with successful attempts. The router flashed amber for a split second then back to the led ring flashing white (not pulsing white). I've tried nmrpflash and it said it was a successful upload. After the upload the device would flash amber. After performing a power cycle on the router I am still not able to set up the system. The led ring is flashing white and the power led is solid green.

This is very frustrating. I can't call netgear support as I purchased this over a year ago on ebay. What steps am I missing? Is there any way to set up the device without using the phone app?
