PS4 Guides and Tutorials

Just under a week ago we reported on PT for PS4 Decrypted followed by some PFS & PSARC Viewers / Extractors, and now emoose shared a guide on unpacking P.T. alongside some related file downloads from Playable Teaser hackers below!

To quote: Here's a dictionary for the texture.qar with all textures named, based off the pathid_list_ps4 file.

MGSV-QAR-Dictionary-Project has also been updated with these filenames

For anyone interested, a small guide on unpacking PT, hopefully I didn't miss anything :

Downloads:

• GameArchives: GameArchives GIT
• psarc-138.002: psarc.zip
• MGSV_ResDec: MGSV_ResDec.rar
• GzsTool: GzsTool GIT
• MGSV QAR Tool: MGSV_QAR_Tool.rar

pfs_image.dat:

• Use GameArchives to open pfs_image.dat and extract chunk1.psarc & texture.qar

chunk1.psarc:

• Use psarc to extract chunk1.psarc:

• Copy MGSV_ResDec to extracted chunk1.psarc folder, in that folder create .bat file with the following:

• Run the .bat file you created, once it's finished all extracted chunk1.psarc files should be decrypted

• Once decrypted, to unpack the .fpk/.fpkd files copy GzsTool to extracted chunk1.psarc folder

• Open a command prompt to the extracted chunk1.psarc folder and run the following (don't forget the . at the end):

• All .fpk/.fpkd files should now be unpacked

texture.qar:

• Extract MGSV QAR Tool to the same folder as texture.qar

Hello PSXHAX Members, today PS4 Developer Zecoxao shared a new PlayStation 4 tutorial proceeding his PS4 Version Spoof covering reading and writing to the PS4 process memory using proc_rwmem for those on a 1.76 Firmware console.

Recently AlexxLopaztico02 shared a guide on updating to a specific PlayStation 4 Firmware version that may be useful for some users not looking to jump all the way to Sony's current PS4 System Software 4.05 revision.

Check it out below, to quote: HOW TO: Update to a specific FW on PS4 (Works For Upd 4.0.1)

With the new jailbreak presentation in GeekPwn, the people who are in FW 3.55 would want to update to 4.0.1, without having to update to 4.0.5 and lose to opportunity to jailbreak (ouch)

Lets put clear that this works for ALL the FW, not to the specific 4.0.1, but in this one we gonna update to 4.0.1

Requirements:

• A Flash USB of 1GB at least
• A PS4 on a FW lower than the one you want to update (Sorry, not downgrading on this one)
• The update file (Link in first step)
• A PC

So, lets start!

0- If you installed a PS4 Update Blocker you'll need to Remove PS4 Update Blocker before you can update your PlayStation 4 Firmware version.

1- First of all, you gotta download the 4.0.1 FW in a PUP file, which you can get clicking this link (mirror here).

Note: if you want another PS4 FW update, check this page (mirror here).

2- Now, format your USB to FAT32 (This will wipe all your data, so make a backup!)

3- Now, make a folder in your flash drive called "PS4" (without the ") Remember it gotta be in UPPER CASE.

4- Inside the PS4 folder, make a folder called "UPDATE" (again without the ") IN UPPER CASE.

5- Copy the file you downloaded at the start of the tut to the UPDATE folder.

6- Rename the file to "PS4UPDATE.PUP"

We're ready in the PC, now lets go to the PS4.

7- First of all, shut down COMPLETELY your PS4.

8- Now, put your finger like...
