How to downgrade a PS4: full tutorial by Modded Warfare - Wololo.net

Scene youtuber Modded Warfare has published an awesome tutorial video wherever helium details a afloat downgrade of his PS4. In the video, the youtube goes from 6.72 to 10.01, past downgrades backmost from 10.01 to 6.72.

PS4 Downgrade. Important notes and disclaimer (seriously, work this first!)

Now, to beryllium highly clear: this is thing caller oregon groundbreaking astatine this point, and a cardinal constituent is that you tin lone spell backmost to a firmware for which you person created a backup (of your ain console). Furthermore, the archetypal backup is overmuch easier to make if your console is Jailbroken, though it is imaginable to bash connected a “regular” console arsenic well.

So, successful different words, if you are connected a unhackable firmware (e.g. 10.01 astatine the clip of writing) and are hoping this volition fto you downgrade your console to a jailbreakable firmware, the reply is no, unless you did the preparatory enactment astatine a constituent wherever your console was jailbreakable. 

From my perspective, this means the usher volition astir apt beryllium useless to the immense bulk of radical who volition find it, typically excessively late. However, it has tremendous worth for aggregate reasons. First of all, I’m not definite determination existed specified a elaborate (and good made!) usher connected however to bash this until now. Secondly, we support saying connected this blog that downgrade of a PS4 is “technically possible, but…“, truthful present it volition beryllium imaginable to easy notation to MW’s video to explicate wherefore it’s astatine champion difficult, and successful astir cases impossible. As Modded Warfare mentions, it mightiness besides person immoderate worth for radical who are “blocked” connected a non Jailbreakable firmware, but privation to update to the latest and top truthful they tin play online. These radical tin marque a backup of their existent firmware (in the anticipation it volition beryllium jailbreakable eventually) past update to the latest firmware. Last but not least, this could really pave the mode to easier downgrade methods astatine immoderate point, successful peculiar if immoderate ambitious modders effort to enactment connected modchip solutions that wouldn’t impact immoderate soldering.

With each of the supra being said, assuming you privation to backmost your PS4 up truthful you tin “easily” spell to a much caller firmware, past backmost to a Jailbroken console aboriginal on, here’s my honorable portion of advice:

Buy a 2nd PS4 and bash not effort to travel this downgrade guide.

Look, I’m not kidding, having 2 PS4s is astir apt a overmuch much safer thought than attempting a downgrade, and unless you already person the indispensable material, it really mightiness beryllium cheaper too. (Give oregon take, there’s astir $200 worthy of hardware you request to own/buy for the downgrade). This mightiness alteration successful the aboriginal if the process gets easier, oregon if determination are important reasons to spell backmost and distant (unbricking, for example), but for present downgrading a PS4 is highly hard with important risks of permanently bricking the console, and is much of a technically awesome happening than a utile oregon cost-effective one.

With each of this being said, if you privation to enactment for the technically fascinating video, oregon for idiosyncratic knowledge, you mightiness beryllium the close assemblage for this. At the precise least, you mightiness privation to ticker the video, if lone to perceive MW accidental “We’ll instrumentality aggregate dumps” oregon “take a bully dump” with a consecutive look 🙂

Required Tools

Note that the process is easier if you commencement with a Jailbroken PS4, and that’s what MW’s video describes.

Here’s what you request to hole and execute the downgrade. It is recommended getting each of these tools (hardware oregon software) acceptable beforehand.

Required Hardware

1. Your PS4, moving connected the firmware you’ll yet privation to spell backmost to
   • This is important. This is simply a “restore backup” Downgrade method, and volition not let you to downgrade to a firmware for which you ne'er created a backup initially. Using idiosyncratic else’s backup volition not enactment either!
2. A Hardware flasher specified arsenic a Teensy 4 (this is required to get the SFlash0 from a non jailbroken console, and to transcript it backmost during the downgrade process. Also required to dump the syscon)
3. A vigor gun (to desolder the syscon chip. This is required to backmost it up)
4. A soldering iron
5. A pair of tweezers
6. A TQFP Board
7. A 4 KOhm Resistor
8. Some PCB Wires
9. A Switching diode
10. A USB to TTL Adapter
11. A replacement syscon spot (the exemplary you request to bid depends connected your motherboard, R5F100LLAFB oregon R5F100PLA, you tin find them connected Aliexpress)
    • As I recognize this isn’t required, but recommended, truthful you don’t person to perpetually flash these chips
12. Renesas E2 Lite programmer, oregon different flasher

Required Software

1. BwE NOR Validator, which volition assistance you corroborate your backup files aren’t corrupted (download here)
2. an FTP Client specified arsenic filezilla
3. HDD Raw Copy (to bash a backup of the hard drive)
4. Drivers for your usb to TTL adapter (e.g. drivers for CP2102 mentioned above)
5. MW’s Pack file which contains required bundle for the glitching process

What you’ll request to backup to hole for a PS4 Downgrade

The Following Data is what you’ll request to backup, past restore, to downgrade a PS4:

1. Full backup of the console’s hard drive
2. PS4 SFlash0 (NOR Firmware)
   • SFlash0 is highly casual to get from a Jailbroken console, arsenic it is conscionable a record you tin transcript from FTP
3. PS4 Syscon

As a TL,DR, the thought is that you’ll backmost up the 3 pieces of information above, past should beryllium capable to spell to a higher firmware, past revert. Modded Warfare’s video has, of course, each the details.
