How to downgrade a PS4: full tutorial by Modded Warfare –

Scene youtuber Modded Warfare has revealed a formidable tutorial video the place he particulars a full downgrade of his PS4. Within the video, the youtube goes from 6.72 to 10.01, then downgrades again from 10.01 to six.72.

PS4 Downgrade. Essential notes and disclaimer (critically, learn this primary!)

Now, to be extraordinarily clear: that is nothing new or groundbreaking at this level, and a key level is you can solely return to a firmware for which you’ve created a backup (of your individual console). Moreover, the preliminary backup is far simpler to create in case your console is Jailbroken, though it’s attainable to do on a “common” console as nicely.

So, in different phrases, if you’re on a unhackable firmware (e.g. 10.01 on the time of writing) and are hoping it will allow you to downgrade your console to a jailbreakable firmware, the reply is not any, until you probably did the preparatory work at a degree the place your console was jailbreakable. 

From my perspective, this implies the information will most certainly be ineffective to the overwhelming majority of people that will discover it, usually too late. Nonetheless, it has super worth for a number of causes. To begin with, I’m undecided there existed such an in depth (and nicely made!) information on how to do that till now. Secondly, we maintain saying on this weblog that downgrade of a PS4 is “technically attainable, however…“, so now it will likely be attainable to simply confer with MW’s video to elucidate why it’s at greatest tough, and typically not possible. As Modded Warfare mentions, it may also have some worth for people who find themselves “blocked” on a non Jailbreakable firmware, however wish to replace to the newest and best to allow them to play on-line. These individuals could make a backup of their present firmware (within the hope it will likely be jailbreakable finally) then replace to the newest firmware. Final however not least, this might really pave the way in which to simpler downgrade strategies in some unspecified time in the future, particularly if some formidable modders try and work on modchip options that wouldn’t contain any soldering.

With all the above being mentioned, assuming you wish to again your PS4 up so you’ll be able to “simply” go to a newer firmware, then again to a Jailbroken console afterward, right here’s my trustworthy piece of recommendation:

Purchase a second PS4 and don’t try and observe this downgrade information.

Look, I’m not kidding, having two PS4s might be a way more safer thought than trying a downgrade, and until you have already got the required materials, it really may be cheaper too. (Give or take, there’s about $200 value of {hardware} it’s worthwhile to personal/purchase for the downgrade). This may change sooner or later if the method will get simpler, or if there are vital causes to travel (unbricking, for instance), however for now downgrading a PS4 is extraordinarily tough with vital dangers of completely bricking the console, and is extra of a technically spectacular factor than a helpful or cost-effective one.

With all of this being mentioned, if you wish to keep for the technically fascinating video, or for private data, you may be the precise viewers for this. On the very least, you may wish to watch the video, if solely to listen to MW say “We’ll take a number of dumps” or “take dump” with a straight face 🙂

Required Instruments

Be aware that the method is less complicated if you happen to begin with a Jailbroken PS4, and that’s what MW’s video describes.

Right here’s what it’s worthwhile to put together and execute the downgrade. It is suggested getting all of those instruments ({hardware} or software program) prepared beforehand.

Required {Hardware}

  1. Your PS4, operating on the firmware you’ll finally wish to return to
    • That is necessary. This can be a “restore backup” Downgrade methodology, and won’t assist you to downgrade to a firmware for which you by no means created a backup initially. Utilizing another person’s backup is not going to work both!
  2. A {Hardware} flasher akin to a Teensy 4 (that is required to get the SFlash0 from a non jailbroken console, and to repeat it again throughout the downgrade course of. Additionally required to dump the syscon)
  3. A warmth gun (to desolder the syscon chip. That is required to again 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 alternative syscon chip (the mannequin it’s worthwhile to order will depend on your motherboard, R5F100LLAFB or R5F100PLA, yow will discover them on Aliexpress)
    • As I perceive this isn’t required, however really helpful, so that you don’t must continuously flash these chips
  12. Renesas E2 Lite programmer, or different flasher

Required Software program

  1. BwE NOR Validator, which can show you how to verify your backup recordsdata aren’t corrupted (obtain right here)
  2. an FTP Consumer akin to filezilla
  3. HDD Uncooked Copy (to do a backup of the onerous drive)
  4. Drivers to your usb to TTL adapter (e.g. drivers for CP2102 talked about above)
  5. MW’s Pack file which incorporates required software program for the glitching course of

What you’ll have to backup to arrange for a PS4 Downgrade

The Following Information is what you’ll have to backup, then restore, to downgrade a PS4:

  1. Full backup of the console’s onerous drive
  2. PS4 SFlash0 (NOR Firmware)
    • SFlash0 is extraordinarily simple to get from a Jailbroken console, as it’s only a file you’ll be able to copy from FTP
  3. PS4 Syscon

As a TL,DR, the concept is that you simply’ll again up the three items of information above, then ought to be capable of go to the next firmware, then revert. Modded Warfare’s video has, after all, all the main points.
