The REBUG team never disappoint the scene and this time they’ve introduced what they call “Toggle QA”. This package basically allows you to SET/RESET your QA Flag.

*** THIS SOFTWARE WRITES TO THE PS3 EEPROM – USE AT YOUR OWN RISK ****

After having to QA a few PS3 in a row. Then installing a different firmware straight after, it was time to cut out the middleman.

Toggle QA will SET/RESET the QA Flag and Token on any 3.41 or 3.55 firmware that has lv1 mmap and lv2 peek and poke patches (which is most of them).

When you run the app it first detects if the PS3 is 3.41 or 3.55. Next it will check if your firmware has any of the required lv1 patches already and only patch the hypervisor with the ones you need. After it finishes patching Toggle QA will check the status of the QA Flag and SET/RESET it accordingly. Then once the QA SET/RESET is done any lv1 patches made will be removed.

HOW TO USE:
1: Install toggle_qa.pkg
2: Run Toggle QA from XMB
3: PS3 will beep and return to XMB. (If you do not hear a beep it has not worked)

NOTE: Every now and then it will hang on the lv1 patching stage. If it has not beeped and returned to the XMB after about 30secs you will need to reboot and try again.

Enjoy.

Big thanks to graf and the gitbrew crew for the hypervisor work.
Everyone involved in getting the QA Flag/Token working back many moons ago.

The Rebug team are at it again and this time they’ve released a 3.73 Version Spoofer, and update packages for those already on the rebug firmware.

Rebug Update Package:

***** THIS DOESNT ALLOW PSN *** USE AT YOUR OWN RISK *****
Install Rebug Update Package 0.3 (3.41.3) or Rebug Update Package 0.5 (3.55.2) to update REBUG’s version spoof files to 3.73 and enable reActPSN 2.0 compatibility. As usual all previous fixes and updates are included.

UPDATER WILL PERFORM THE FOLLOWING TASKS
Update the Rebug Selector package to Rebug Selector 1.5.1 and 1.6.1(Finally got around to fixing the display resolution on HD tv’s)
Update the current version spoof files to 3.73
Add reActPSN 2.0 compatibility(Credit to Hotz8611)
INSTALL1: Install Rebug_Update_Package.pkg file from XMB2: Run Rebug Update Package from the [Games] menu3: Follow the on screen prompts4: PS3 will reboot if needed when finished

NOTE: Once the PS3 has rebooted you can delete Rebug Update Package from your XMB as it is not needed.
NOTE: Rebug Selector 1.5.1 and 1.6.1 are identical in their function but for some reason on random PS3 Rebug Selector 1.5.1 (Which we consider to be the more user-friendly) freezes. We have included them both just incase.

Rebug v3.73 Spoofer:

***** THIS DOESNT ALLOW PSN *** USE AT YOUR OWN RISK *****

*********** THIS WILL NOT WORK ON REBUG FIRMWARE ***********

Sorry on the delay, 3.73 Version Spoofer 2.1 is now available for 3.41 and 3.55. This time around we have added a little extra flavour in the form of reActPSN 2.0 compatibility for both your normal and spoofed vsh.self. The app backs up your current files before activating the spoof, then auto reboots leaving no room for end-user error.

INSTALL:
Press L1+CROSS to INSTALL 3.73 Version Spoof files to your PS3

ACTIVATE/DEACTIVATE:
Press L1+CROSS to ACTIVATE/DEACTIVATE (System will reboot)

UNINSTALL:
Press L1+CIRCLE to UNINSTALL (this will deactivate the spoofer, remove the spoof files from dev_flash and reboot if needed)

NOTE: Your PS3 will need to be restarted to use reActPSN 2.0 if you HAVE INSTALLED but NOT ACTIVATED the Version Spoofer.

Enjoy

As most of you know already, there is a dongle out there in the wild, a dongle manufactured/created by so called scene developers, who in reality should be giving this device or method of exploit for free, like so, so may great developers in the PS3 scene have done, the dongle i am talking about, that sucks the very last drop of blood from the PS3 Scene, is “True Blue”.

Anyhow, enough honesty about the device, onto the real reason for creating this news post, is that the awesome guys behind Rebug, have released a True Blue friendly version of their Rebug CFW for those naive enough to buy the dongle, here is a quote from Rebugs website:

*** WARNING – DO NOT INSTALL THIS UPDATE IF YOU DO NOT OWN A TRUE BLUE DONGLE ***

After thinking it over the team came to the conclusion that in the not to distant future, there will be a whole lot of unhappy REBUG users who want to enjoy their new True Blue Dongle only to realise that their hard earned save games which ran using the Fake Save Data Owner option will no longer work.

As a courtesy for our loyal users we have put together REBUG 3.55.2 TB EDITION.

The Codename: Rebug Team take NO CREDIT for the COREOS work as we are using the True Blue CFW COREOS with the REBUG dev_flash files (straight swap, everything works so far!!).

FEATURES INCLUDED/ADDED/UPDATED

INCLUDED – All REBUG 3.55.2 Features

INCLUDED – True Blue CFW COREOS
(Requires True Blue Dongle to run True Blue patched 3.60+ Games)

ADDED – reActPSN 2.0 compatibility
(Credit to Hotz8611)

ADDED – No act.dat deletion on reboot
(This is our own. We feel it is a little bit cleaner than the original reActPSN 2.0 patch)

UPDATED – 3.73 Version Spoof files

UPDATED – Rebug Selector 1.5.1 & 1.6.1
(Finally got around to fixing the display resolution on HD tv’s)

INSTALL:
REBUG 3.55.2 TB EDITION can be installed over the same or lower version OFW/CFW/MFW on any model PS3 through the XMB or Recovery Mode.

UNINSTALL:
REBUG 3.55.2 TB EDITION can be uninstalled with the same version OFW/CFW/MFW on any model PS3 through the XMB or Recovery Mode.

PLAYING BACKUPS:
Just like the Official True Blue CFW, after installing REBUG 3.55.2 TB EDITION the True Blue Dongle MUST be connected to the PS3 for ANY of your backups to run.

NOTE: Rebug Selector 1.5.1 and 1.6.1 are identical in their function but for some reason on random PS3 Rebug Selector 1.5.1 (Which we consider to be the more user-friendly) freezes. We have included them both just incase.

Enjoy

I start developing PS3MFW Builder 0.2.1 a few mouths ago, and since then it’s just laying around my computer.
It’s fully working, only one function should rewritten.

Features:
Settings:
- Choose language.
- Select Temp folder.
- Select PS3_KEYS folder.
- Save/Default all the settings, including selected/unselected tasks, original/modified firmware paths, theme and so on.
- For developers: you can restart PS3MFW Builder by pressing Shift-R .

Languages:
I added the option to translate PS3MFW Builder to any language, including RTL, unique symbols and so on..
Thanks to eussNL for creating most of the translations.

You can also easiely create your own translation, all the text it stored in an .xml file.

Tasks:
- Added the option to select multiple files using “files” option type.
- Added the option to select directory using “directory” option type.

Developers: The only thing should be rewritten is the “save_settings” function.
The best way is to add a function in xml.tcl which will replace the text in specific node.

PS3 Hacker, No_One contacted us a few months ago giving us a status update on his PNM project. For those of you who don’t know the PNM project is a way to find  firmware 3.6+ (I am assuming this includes 3.7+ as well) public keys, which as you know will lead to new CFW etc…

No_One has exclusively contacted us again today bringing more updates on his latest developments. The project is now in its last stages and it is not able to power on/off the PS3 automatically. No_One also clarifies he will not be releasing the keys, but is giving YOU [or some other clever hacker] to do it (probably doesn’t want legal troubles like Geohot).

To quote:

Hi mates,

I wanted to announce that PNM project has entered its last stage.
PNM is now wired to the motherboard of a SLIM PS3 : DYN-001.
The first results are fine. PNM is correctly powered by the PS3 itself.
Much better, PNM is now capable to power on/off automatically the PS3.
Firmware is choosen using a jumper.
Here is how it will work (very soon) :
- remove the power cable
- place the jumper to choose Firmware #1 or Firmware #2
- connect the power cable
And then the PS3 starts automatically without human interaction.

Let me clarify some points read here and there.
I never promised the 3.6+ public keys !
I just said that PNM will allow to find them nothing else.

This project is a hobby. I work as fast as I can.
Please stop the lame remarks concerning the delay !

I will come back soon with the final video demonstration.

Cheers

No_One

Great news indeed, always nice to see there are people doing work progressing the scene instead of constant arguing

PS3Hax member, Rogero, has released Rogero  CFW version 2. This CFW is for people that have downgraded their consoles. This new release is much more stable and has the famous Kmeaw CFW as the “base”.

To quote:

This is a better optimized version of the previous MFW released, This one is a Custom firmware
built manually by patching and packing the files and the final PUP package using the well known
“failoverflow” public set of tools and having “Kmeaw” as the base firmware unlike it’s previous
version which was a Modified firmware built using the famous MFW builder application and using
an OFW3.55 as the base firmware.

Full thread+download can be seen HERE or at the Discuss in Forums link.

So DemonHades and jaicrab along with their group of developers have been working for quite a while on a 3.41 CFW, which implements the Cobra payload, it also allows for playing games directly from the XMB, without the need of a backup manager, this FW was only for PS3 consoles on firmware 3.41, but does this new post from the source, mean it will also work on firmware 3.55 or even firmware 3.56 ???

Here is a quote of the post in question, translation by PS3HaX member CaptainCPS-X(Thank you).

Before reading any further, if you’re looking for something related to FW 3.60 or PSN, don’t bother reading

Hello friends, as we said JFW DH was going to work only on FW 3.41, well now we bring JFW DH 3.56.

- At this moment, the new JFW DH can only be installed over FW 3.55 or over 3.56 by patching part of the update with a hardware flasher (I recommend teensy, is the cheapest and easier to handle).

What can be done with JFW DH 3.56…

- Launch homebrew
- Loading of backups without managers (multiMAN)

What can’t be done at this moment…

- Once on 3.56 you can’t downgrade, due to the new update system that we explained some time ago.
- The Grid cannot be used (for now).
- Downgrade is only possible with a flasher, but if you enter factory mode you will not be stuck anymore, you will be able to exit…we have not touched the QA yet, but it could be a way out .

Remember Rogero? The man behind Rogero Backup manager? Well he has released some information about the downgrade from 3.70 by Dospiedras and states that any MFW that does not have LV1.self file patched to Disable all checks will result in a brick.Now he has released his own MFW that fixes this trophy error.

Team EDIY is creating some hot news lately and this one might just drop the bomb on those who already have a jailbroken 3.55 console. For those of you that don’t know the E3 flasher is a chip, similar to Progkeet, that is releasing a SOLDERLESS solution and allows you to downgrade (click here for more info).

Today team EDIY contacted us bringing another video showing dual booting form 3.70 to 3.55, in one simple click and in seconds! Reminds me of the good devhook days on the PSP, looks promising and you can bet this is the best solution your going to get with PSN with CFW without dishing out for a second PS3!

The video below shows the quick switching of the firmwares, notice that the MAC ID for the PS3 consoles is the same throughout the video:

Here is the email I received this morning:

E3DIY team success dual boot with E3 FLASHER, you can switch 3.7 and 3.55 in few only a few seconds!

- Easy with 1 key operation.

- E3 company will release all details like picture, installation, operation and price next week.

-Team E3DIY get another great progress for PS3 with E3 FLASHER, it will release at the same time next week.

- PS: 4times switch showes same MAC address, to prove it is the same console.

With bringing a solderless solution this flasher seems very interesting now and opens up the market to many people, answer the poll below and let us know what YOU would do.

Team E3DIY is in contact with us, so stay tuned for more exclusive news @ PS3Hax

So as most of you know, the PS3 Scene just recently celebrated the one year anniversary of the PS3 being hacked/jailbroken, many, many things have happened in that short year, many changes and break throughs, i have two reasons for creating such a FAQ, the obvious being all the changes, PS3 owners just getting into the scene, need help and guidance, i also seen a failed attempt at a F.A.Q on another site and i thought that mistake needed to be rectified, with a proper F.A.Q

(Q) Why Would I Hack/Jailbreak My PS3 ?
(A) Hacking your PS3, gives you so many new option’s, you will be able to use emulators, homebrew apps and game backups as well as being able to use Linux, after Sony removed the function in firmware 3.21.

(Q) Is there a firmware my PS3 should be on ?
(A) It seems the preferable firmwares are 3.15(For the real OtherOS), 3.41(The original “Jailbreak” firmware) and 3.55(the first CFW PS3), 3.55 is the favourite and most used.

(Q) What Firmwares cannot be hacked yet ?
(A) 3.56 to 3.70 are unhackable at the moment, perhaps it will remain that way, or perhaps we will see a break through in the future, only time will tell.

(Q) But when i bought my PS3, the firmware was above 3.55/My family member updated my console when i was out , how can i have Homebrew ?
(A) All hope isn’t lost, you can downgrade your consoles firmware with devices like progskeet, at the moment, this is rather a tedious process, involving soldering several wires to your PS3, but in the future we will have solderless models of these products, for information on how to downgrade, check this thread:
Noob Tutorial: How to downgrade/flash your PS3 from firmware 3.70 to 3.55 via ProgSkeet/Teensy++ and install 3.55 Kmeaw CFW

(Q) Downgrading was a pain, i don’t want to go through that again, is there a way i can protect my PS3 from accidental upgrading ?
(A) You can use Team Rebugs firmware spoofer, it spoofs the firmware, so that when someone attempts to update the PS3, via internet or disc, the PS3 tells them they are already on the highest firmware, as an extra precaution, you should remove your consoles access to the PS3, when you are not around, you can grab your spoofer, from the offical Rebug site here.

(Q) What other firmwares can i hack/jailbreak my PS3 on ?
(A) 2.76, 3.01, 3.15, 3.21, 3.40, can all be “hacked” using the PS Jailbreak USB Dongle or equivalent variants, information on the useable devices, can be found on my old F.A.Q, which you can view here.

(Q) CFW/MFW Or Dongle ?
(A) CFW/MFW is the way to go, dongles are more or less dead, apart from the Cobra USB dongle, but it too will become obsolete as its features get implemented into CFW/MFW, also with CFW/MFW, you do not need to do the start-eject combo that is needed with the dongles.

(Q) How do i install CFW ?
(A) If you aren’t already on 3.55, you will need to update to the official Sony firmware, then install a CFW via recovery, Pirate wrote a great guide, which you can read here:
[Tutorial] How to play and install Backups with Kmeaw CFW+PSN without risk of brick or itskamel’s NOOB JAILBREAK GUIDE
If you wish to stay on official firmware 3.41, the same method applies, but you will need to grab Team Rebugs 3.41 CFW, which you can find here.
Here is a video of Kmeaw being installed via the Recovery Method.

(Q) I see many different CFW/MFW, which one should i chose ?
(A) As i stated earlier, Kmeaw is the most popular CFW/MFW but there are other versions and you can take your pick, all installed the same way as the above method:
Team Rebugs 3.41/3.55 CFW
BobbyBlunt’s PS3HaX MFW
Thelostdeathknight’s PS3HaX MFW
varaques MFW
bitsbubbas NFW
bitsbubbas NFW With Cobra Implimentation

(Q) I want to test a different CFW/MFW, is it ok to install a CFW on top of another CFW.
(A) If you have Kmeaw installed, you can install Rebug over the top of it, but if you decide you don’t like Rebug and want to go back to Kmeaw, it is advised that you install the 3.55 Official Firmware, then install Kmeaw, as a precaution, i would advise that is done with all CFW changes

(Q) Ok so i have CFW installed, how do i run homebrew ?
(A) You will see in the game section, you will see “Install Package Files”, you will be able to install all your homebrew and backup managers from there, just a note though, the PKG files that you are installing, need to be on the root of your FAT32 formatted thumbdrive/external HDD.

(Q) Now that i have updated to 3.55 CFW, is there a list of working homebrew app’s/games ?
(A) Here are a few links:
Homebrew Games Collection(Maintained by manster)
Homebrew Emulator Collection(Maintained by Thelostdeathknight)
Homebrew Application Collection(maintained by GregoryRasputin(me)

(Q) How do i play my backups ?
(A) You will need a backup manager, the following are available(We recommend the PS3HaX endorsed multiMAN):
multiMAN For help, check the (Support Forum) Grab BDEMU2 here.
Rogero
Gaia
Iris
Open Manager(Firmware 3.41 Only)
Hermes Manager(Firmware 3.41 Only)

(Q) I have my games backed up, i now want to play online, how do i do that ?
(A) Currently there is no way to access the PSN server to play online, even if a new CFW came out, Sony would block PSN again with a new OFW, so your only real option, if you want both homebrew and PSN, is to have two PS3′s

(Q) What are my storage options for backing up games ?

(A.1) You can backups certain games to CD/DVD/BD disc’s, read here for more information.
(A.2) You can install games on the PS3′s internal HDD or use an External USB HDD, which needs to be formatted to FAT32, you can also use a FAT32 USB Thumb Drive, note that with FAT32 you are limited to games with single files under 4GB, if you prefer all your games to be on the internal HDD, you can get up to 1TB 2.5? HDD, or you can use the Xecuter PS3 HDXT method and have your internal HDD on the outside of the machine, the benefit of this, is that you can use 3.5? Sata and IDE HDD’s as internal storage.
Some more PS3 HDD Information submitted by ieder-zijn-meis(Thanks again)
- maximum height is 9,5mm (many 2.5? drives above 640GB are too high too fit inside)
– maximum PS3 filesystem is 1TB (512KB block size)
– maximum FAT32 theoretical size is 8TB, practical limit on the PS3 is 2TB
– 7200rpm can be used, as well as Flashdrives (although the 1/5th lower loadingtime of GTA5 can be considered too low to justify the higher pricetag of SATA Flashdrives.
– SATAII-300 can be used, although it will work on SATA1-150 speed interface.
– If using external 3.5? drives hooked up to the internal SATA, you’ll need an external powersupply (some drivebays include them).
– If on low budget or you like DIY: use a normal extension (male to female) SATA cable (and make sure it doesn’t get loose) and recycle the case + powersupply of an external USB harddisk (without using the USB connection/conversion).
– Don’t use RAID or SAN drives with (e)SATA interface, just a plain single drive with a bare SATA connector (many controllers don’t work without drivers/software).
– Games can be hardcoded for BluRay speeds (9MB/s) so sticking a 85~220MB/s harddrive inside will not speedup everything/allways (but most do).
– If you plan on exchanging the drive, download the full PUP of your FW you are using and put it on an USB Mass Storage Device formatted with FAT32 in PS3UPDATEPS3UPDAT.PUP and disconnect the LAN before re powering the PS3 (or you’ll bound to end up with the latest (3.55 now) unjailbreakable/undowngradable version).
– Use a good fitting X screwdriver, the screws fitted to the HD<>tray are made of very soft aluminum.

Here is a tutorial, by forum member Invi, on how to an External IDE HDD Case and use it as Internal Storage:
HowTo: Use an external IDE HDD Case to connect an Internal 3,5″ Sata HDD as PS3 HDD.

An image of the Xecuter PS3 HDXT.

Videos of different HDD expansion options.

(Q) Now that i am on 3.55, can i install Linux ?
(A) Follow this thread.

(Q) Ok im fed up with using my thumb drive, is there a way to download apps directly to the PS3.
(A) Yes,you will need to instal “Package Installer”, then you will be able to FTP the apps to the “packages” folder on your PS3, you can find more about that here.

(Q) Ok so i have backed up a game, i want to save that game to my computer as an extra backup, or i want to mod the game, how do i transfer it from my PS3.
(A) There are two methods, FTP, there are three of those at the moment:
PS3 FTP Server by CJCP
blackb0x FTP Server by blackb0x
OpenPS3FTP(Probably the most stable)
Alternatively you can use
Comgenies Awesome Filemanager
or
Simple Filemanager
multiMAN also has FTP and Filemanger options
if you cant use FTP, or have an External HDD, Comgenies Filemanager is the best choice.

(Q) I just bought a new game, tried to play it, but it says i need to update my firmware, what do i do ?
(A) Unfortunately, newer games being released, will be unplayable on current CFW’s, you may be lucky and get a patch, but the chances of those are getting slimmer as time goes on, so the only options you are left with, are update or buy a new PS3, this is the sad situation of the scene, until the scene developers release a new CFW, you will be unable to play the newer games you bought.

(Q) I want to be able to create my own Homebrew, is it possible.
(A.1) Yes, using the Open Source PS3 SDK, named PSL1GHT, you can create Homebrew, PSL1GHT was created by AerialX, read about it here.

(A.2) You can use the Official Sony SDK, it is reported that this is better for creating homebrew, than the open source version.

(Q) I backed up a few of my movies to .AVI and .MKV formats, but when i try and play them through Showtime, or stream them via PS3Media Server, i get a Cinavia warning, is there any way past this ?
(A) You can install this app:
Disable Cinavia Installer (3.41 & 3.55)(By Team Rebug)

(Q) Can play PS2/PS1 backups on my Jailbroken PS3 ?
(A.1) You can use this method, it lets you use Swap Magic to load PS2 backups on your PS3, the only consoles allowed, are those that are Backwards Compatible, this option also works on a non Jailbroken PS3, even with firmware 3.70
(A.2) You can use the Cobra USB dongle, to play PS1 or PS2 backups on your Jailbroken PS3, it is compatible with firmwares 3.41 and 3.55.
(A.3) You can use this method to play PS1 backups on firmware 3.41 and 3.55.

You don’t want to downgrade your PS3 on OFW 3.70 (you’ll loose all your data), but want to enjoy Homebrew and capabilities of Official Firmware 3.70 with one Console? Then this is the right tutorial for you. DiGiTaLAnGeL from Italy has managed to “fast-swap” between Custom Firmware (3.55) and Official Firmware (3.70) with the ProgSkeet Flasher and a second Harddrive.

All right everyone it seems that team REBUG is up to it again. They are currently in the testing stages of running a full debug firmware on a retail ps3, Which many have said is impossible. As of right now REBUG firmware CoreOS is still CEX, with debug features enabled. More info below.

In this video you can see the PS3 first booting and then BEEPING.

* This is normal, if someone installs an full official DEBUG PUP via Service Mode on a Retail Console.

Next you see Cyber booting on his PS3 using a USB Jailbreak Dongle!

* This time the PS3 boots-up and is a fully 100% DEBUG firmware, no crashing or beeping, loads right into the XMB!

This is all possible by the Codename: REBUG team developing their own “custom payload” loaded for usage on the old v3.41 Jailbreak dongles!

Quote of a message from Cyberskunk to GaryOPA

Hey Gary,

The vid we sent you uses a dongle to boot the DEX COREOS on retail console as we thought that to be more conclusive since you can mimic the DEX XMB quite easily..

We can however boot it without the dongle but before everyone gets excited being able to boot the DEX COREOS and getting all of its functions up and running without rehashing (converting) your console are two completely different problems.

Cheers Mate..

Most of you have heard the news of the PS3 slim downgrade on firmware 3.70, helping those buying newer or updated PS3 slim consoles to the scene. At the moment push aside “soft modding” and its time to bring on the good ole’ soldering iron back out.

This new method of downgrading basically requires the soldering of a multi-console-compatible chip known as ProgSkeet (or clone) which you can find or purchase HERE…or you can use Teensy++ board if you still have those from the good dongle days. A solder-less ProgSkeet is in the works, more info here.
