Twitter user @nicolasfreires shared this video recently on youtube. It’s a detailed Video tutorial on how to dump the PS4 NOR, using a Raspberry PI 2 and the JAISPI tool.
Although the technique to dump the PS4 NOR is nothing new, this is the first time we’re getting such a detailed Tutorial in Video. On the video, you’ll see that in addition to the stuff mentioned below, the modder uses a convenient board to attach the Flash, without having to do manual wiring. Wiring things manually could prove difficult, and people have recommended creating your own PCB or getting a board like the one in the video.
The PS4 “Jailbreak” basics
The video below basically showcases the basics of the infamous “Brazilian PS4 Jailbreak” that we revealed a few month ago.It is worth noting that hackers have mentioned this method will result in a brick on recent PS4 firmwares (if you write to the NOR), don’t do it at home unless you know what you’re doing. The video only shows here how to read the NOR, not what people do after that which lets them pirate games, but that’s the basic idea.
For those willing to seriously give it a try, AlphaHack has a very detailed explanation in English on how he extracted the NOR from his console and soldered it the right way (basically the steps that this video does not show). You can get his full guide here.
Edit: yes, we’re aware this is not a “jailbreak” in the traditional meaning of the word, but this is how people have been refering to it so far, so we’ll stick to that. Deal with it!
Installation is complete. By Putty you can access the Raspberry Pi. To run the command jaispi you need to be root (sudo-s):
# sudo -s
# Jaispi -i / dev/spidev0.0
-i /dev/spidevX.X Get ID from flash
-r file.bin /dev/spidevX.X Read entire flash to file
-e /dev/spidevX.X Erase entire flash
-p file.bin /dev/spidevX.X Only write blocks differences from file
-v file.bin /dev/spidevX.X Verify blocks with file
