The ESP8266 seems to be the device of choice for those of us who want to run a webkit exploit locally without having to use a big computer*. I recently ordered one and didn't find the time to properly explain how to set it up, until now. The following tutorial is for people using Windows 10. Some of the steps might be different if you run on a different OS (or a different flavor of Windows) In this example, I will be installing and running the 5.05 PS4 Exploit, using the version compiled for the ESP8266 by C0d3m4st4. There are other binaries available from other tinkerers, but this one seems to be the most popular right now (and it's fairly easy to use once installed on the ESP8266). You'll need: An ESP8266. I use a NodeMcu v3 by Lolin, but there are multiple clones and they all should work as long as they have at least 4MB. Here's one that works. [ Register or Signin to view external links. ]

A usb-to-micro-usb cable (that's your typical android phone cable, or the one from your Dualshock 4) to connect the ESP8266 to your PC, then later to your PS4.
A firmware binary for the ESP8266, hosting the PS4 5.05 exploit. I used ESP8266XploitHost 2.4 by C0d3M4st4 (source)
A flasher tool that will help you copy the firmware from your PC to the ESP8266 device. Most people will want to download the x64 exe file.
A PS4 running firmware 5.05. Here's a guide on where to get one. (if you have a firmware lower than 5.05, it's easy to upgrade. If you have a firmware higher than 5.05, you cannot downgrade and you need to buy a hackable PS4)
Optional? Some people say you'll need a driver for your PC to recognise the device. I did not need a driver for windows10, but you might need the one that matches your OS from this page
