Are you upgrading with a wireless connection? If you are don't. Use Ethernet.
Make sure the PS4 has the latest updates (5.55).
Use internet explorer and disable any add-ons like adblock. The emergency firmware upgrade should work since it bypasses the encryption put on the firmware on 1.02 and above. I will have a tech test to verify.
Are you getting to the emergency firmware page or just the standard GUI screens?
Just to make sure the steps you are doing are correct: (note the 30/30/30 thing doesn't work with dlink routers)
Press the power button on the router to turn off. Hold down the reset button with a paperclip and press the power button to turn on. Wait about 10 seconds and release. The power LED will blink red.
You need to statically assign your computer 192.168.0.2 and subnet mask 255.255.255.0. Don't worry about dns or gateway addresses. Use Ethernet and plug into a LAN port. Open Internet Explorer and enter http://192.168.0.1. The D-Link Recovery page will appear. If you are asked for a login or the wizard appears, it didn't work.
Browse to the bin file (v1.01) and click upload. During the upload process your browser may time out. Wait until the router LEDS are solid green (except the globe icon may be orange depending on your ISP). Close your browser and reopen it. Go to http://192.168.0.1 and hopefully the login will appear. To see the firmware version enter http://192.168.0.1/version.txt
Let me know if this works or what happens during the process. I can forward to customer service and see what they can do.
Everything was done via ethernet and the PS4 did have 5.55 installed at the time of my previous post.
I used stock IE to connect to the router to get to the Emergency Mode page and tried flashing v1.02 as
FurryNutz said. v1.02 failed instantly. I noticed you said to
press the power button in your reply, and not pull the power cord like how the previously linked
Emergency Recovery Mode instructs you to do. I pulled the plug when trying to flash v1.02. I tried flashing again in Emergency Mode, but left the power cord in and pressed the power button before following the steps provided. Pressing the power button, and
not pulling it, allowed me to successfully flash v1.01 since the PS4 would not connect with v1.02 installed.
