*** USE AT YOUR OWN RISK *** The FW 4.00 just released few days ago. Since the webkit exploit may be patched on 4.00 or the next firmware, I tried to find a way to bypass the update checker of PSN. Then I found PSProxy. Unfortunately, it only support Windows. So I've made a proxy that can work on both macOS and linux (tested on Ubuntu 16.04). Like PSProxy, PSPypass will allow you bypass the update requirement of PSN and let you stay on a lower FW. To use this, you need to have some knowledge about how to use terminal on your OS. Download link: https://github.com/hirakujira/PSPypass *** USE AT YOUR OWN RISK *** I am not responsible if your console be banned by PSN. Use this utility at your own risk! Instructions: On your computer / server: Download the whole project from the above link Edit pspypass.py with your favorite text editor Change region_id to your console region, and change os_version to your current FW version or below Run pspypass.py in terminal. To specific a port, just add the port number like pspypass.py 8888 On your PS4 console: Delete any update file if it's downloading or already downloaded. Set internet connection with proxy. If you don't know how to do, then just google it. Test whether you can connect to the internet with proxy. It may still ask you to update your FW or can't login PSN, but it's ok. Restart your console Now you can login to PSN Advantages of PSPypass: Works on macOS / linux Since it supports linux, you can deploy the proxy on a VPS like DigitalOcean, so you don't need to run the proxy on your computer every time. If you host the proxy on a public server, you can share the proxy with your friends. Limitations: Some applications still need latest FW. Such as Spotify 2.0 RemotePlay client on PC/Mac would ask you update your console For more instructions, please check the README.md in the project.
