PUP (Playstation Update Package) is the file format of the PSP, PS3, PSVita and PS4 system software update packages.
PUP (Playstation Update Package) is the file format of the PSP, PS3, PSVita, PS4, and PS5 system software update packages. It contains updated firmware and files for devices such as the GameOS, Syscon, Wi-Fi, Bluetooth, Communication Processor, Southbridge, Bluray Drive, and more.


PUP embed updates for devices such as the GameOS, Syscon, Wi-Fi, Bluetooth, Communication Processor, Southbridge, BD drive.
== PUP Structure ==


== Structure ==
PS4 update files differ from previous PlayStation consoles in that they embed multiple PUP fragments. The "main" file that is distributed and downloaded to the PS4 console is a SLB2-packed (or "BLS") file which contains PUP fragment files. On retail and TestKit, it typically contains two PUPs (`PS4UPDATE1.PUP` and `PS4UPDATE2.PUP`), while DevKit may have four. These PS4 PUP files are similar in structure to PS4 Signed ELFs (SELFs). Each PUP fragment is responsible for containing different sets of files.


PS4 PUP is special because it embeds single other PUPs.
* PS4UPDATE1 is the "core" update file and contains updates for GameOS/x86 kernel and usermode, Bluray Drive, EAP, EMC, Syscon, SAM, and other firmware stored on the SPI flash.
* PS4UPDATE2 contains the `system_ex` partition of system applications.
* PS4UPDATE3 (DevKit only) contains the preinstall image for DevKit.
* PS4UPDATE4 (DevKit only) contains a seemingly empty preinstall part 2 image for DevKit (maybe reserved?).


=== Header ===
All PUP fragments contain the end-user license agreement, the Orbis Software Updater (orbis_swu), and a watermark.


Have a feeling the header for the new PS4 PUPs ends with a LZMA dictionary and file size… (ie a normal lzma header without the properties byte) anyone else done research into that? As in:
=== File Header ===
 
The file header for the main PUP file is an SLB2 file. Each PUP fragment packed into it has the following header (note: after the initial 0x10 bytes, the remaining 0x10 bytes are encrypted along with the metadata that follows it).


<source lang="c">
<source lang="c">
struct PUPPS4Header {
struct ScePupHeader {
uint32_t magic; // PS4PUPMAGIC "\x4F\x15\x3D\x1D"
uint32_t magic;                 // 0x00 - PS4PUPMAGIC "\x4F\x15\x3D\x1D"
uint16_t version; // Big Endian (??)
uint16_t version;               // 0x04 - Big Endian (??)
uint16_t unknownOne;
uint16_t unknown_one;          // 0x06
uint16_t unknownTwo;
uint16_t unknown_two;          // 0x08
uint16_t unknownThree;
uint16_t flags;                // 0x0A
uint32_t dictSize; // LE afaics
uint16_t header_size;          // 0x0C
uint32_t uncompressedSize; // LE afaics
uint16_t metadata_size;        // 0x0E
 
// From this point on, the header is encrypted...
uint16_t file_size;             // 0x10
uint16_t segment_count;         // 0x18
uint16_t metadata_entries;     // 0x1A
uint32_t unknown_three;         // 0x1C
}; // Size: 0x20
</source>
 
=== Segments ===
 
From this point on, the remaining structures are encrypted in raw update files (though this section can be seen by using the system as an oracle to decrypt PUPs). Following the header is the segment table, which has segment entries that contain information about update entries (a list of which can be found in the "Indices" section).
 
<source lang="c">
struct ScePupSegmentHeader {
uint64_t flags;                // 0x00
uint64_t offset;                // 0x08
uint64_t compressed_size;      // 0x10
uint64_t uncompressed_size;    // 0x18
}; // Size: 0x20
</source>
 
While offset, compressed_size, and uncompressed_size fields are self-explanatory, the flags field packs a lot of information. Below are known flags:
 
<source lang="c">
#define PUP_SEGMENT_ID(x)                  (x->flags >> 20)
#define PUP_SEGMENT_IS_INFO(x)              ((x->flags & (1 << 0)) != 0)
#define PUP_SEGMENT_IS_ENCRYPTED(x)        ((x->flags & (1 << 1)) != 0)
#define PUP_SEGMENT_IS_SIGNED(x)            ((x->flags & (1 << 2)) != 0)
#define PUP_SEGMENT_IS_COMPRESSED(x)        ((x->flags & (1 << 3)) != 0)
#define PUP_SEGMENT_HAS_BLOCKS(x)          ((x->flags & (1 << 11)) != 0)
#define PUP_SEGMENT_HAS_DIGESTS(x)          ((x->flags & (1 << 16)) != 0)
#define PUP_SEGMENT_BLOCK_SIZE(x)          (1 << (((x->flags >> 12) & 0xF) + PAGE_SHIFT)) // Note: PAGE_SHIFT = 0xC
</source>
 
In most cases (ie. "data" segments as opposed to info segments), the segment ID indicates the type of firmware or file to update (see [[#Indices]] table). In the case of info segments, the segment ID points to the index of the "data" segment it contains information for. Info segments are typically only seen when the file or firmware utilizes block-based segments.
 
=== PUP Info ===
 
After the segment table is a section that has additional information on the PUP, such as its target firmware and various flags.
 
<source lang="c">
struct ScePupInfo {
uint32_t fw_ver;                // 0x00 - Firmware version in integer format (ie. FW 9.50 is 0x95080000000)
char unknown_one[0x14];        // 0x04
uint32_t type;                  // 0x18 - Beta/Retail/Testkit/Devkit/Proto
char unknown_two[0x4];          // 0x1C
uint32_t flags;                // 0x20
uint32_t req_fw_ver;            // 0x24
char unknown_three[0x8];       // 0x28
}
}
</source>
</source>
=== Metadata ===
Following the info structure is the metadata table. These entries contain crypto material such as intermediate keys for decrypting and verifying segments. Each segment should have a metadata table entry.
<source lang="c">
struct ScePupMetadataEntry {
char aes128_key[0x10];          // 0x00 - AES128 data decryption key
char aes128_iv[0x10];          // 0x10 - AES128 data decryption initialization vector
char digest[0x20];              // 0x20 - SHA256 digest
char digest_key[0x10];          // 0x40 - SHA256 digest HMAC key
}; // Size: 0x50
</source>
=== Unpacking Notes ===
* Encryption is applied on segments post-compression.
* Non-blocked segments are a straight copy or decompression operation.
* Processing blocked segments requires looking up the accompanying info segments and parsing the block tables within them.
* Large disk images and most SLB2/BLS files will be block-based.

PUP (Playstation Update Package) is the file format of the PSP, PS3, PSVita, PS4, and PS5 system software update packages. It contains updated firmware and files for devices such as the GameOS, Syscon, Wi-Fi, Bluetooth, Communication Processor, Southbridge, Bluray Drive, and more.

PUP Structure[edit | edit source]

PS4 update files differ from previous PlayStation consoles in that they embed multiple PUP fragments. The "main" file that is distributed and downloaded to the PS4 console is a SLB2-packed (or "BLS") file which contains PUP fragment files. On retail and TestKit, it typically contains two PUPs (`PS4UPDATE1.PUP` and `PS4UPDATE2.PUP`), while DevKit may have four. These PS4 PUP files are similar in structure to PS4 Signed ELFs (SELFs). Each PUP fragment is responsible for containing different sets of files.

  • PS4UPDATE1 is the "core" update file and contains updates for GameOS/x86 kernel and usermode, Bluray Drive, EAP, EMC, Syscon, SAM, and other firmware stored on the SPI flash.
  • PS4UPDATE2 contains the `system_ex` partition of system applications.
  • PS4UPDATE3 (DevKit only) contains the preinstall image for DevKit.
  • PS4UPDATE4 (DevKit only) contains a seemingly empty preinstall part 2 image for DevKit (maybe reserved?).

All PUP fragments contain the end-user license agreement, the Orbis Software Updater (orbis_swu), and a watermark.

File Header[edit | edit source]

The file header for the main PUP file is an SLB2 file. Each PUP fragment packed into it has the following header (note: after the initial 0x10 bytes, the remaining 0x10 bytes are encrypted along with the metadata that follows it). 

struct ScePupHeader {
	uint32_t magic;	                // 0x00 - PS4PUPMAGIC "\x4F\x15\x3D\x1D"
	uint16_t version;               // 0x04 - Big Endian (??)
	uint16_t unknown_one;           // 0x06
	uint16_t unknown_two;           // 0x08
	uint16_t flags;                 // 0x0A
	uint16_t header_size;           // 0x0C
	uint16_t metadata_size;         // 0x0E

	// From this point on, the header is encrypted...
	uint16_t file_size;             // 0x10
	uint16_t segment_count;         // 0x18
	uint16_t metadata_entries;      // 0x1A
	uint32_t unknown_three;         // 0x1C
}; // Size: 0x20

Segments[edit | edit source]

From this point on, the remaining structures are encrypted in raw update files (though this section can be seen by using the system as an oracle to decrypt PUPs). Following the header is the segment table, which has segment entries that contain information about update entries (a list of which can be found in the "Indices" section). 

struct ScePupSegmentHeader {
	uint64_t flags;                 // 0x00
	uint64_t offset;                // 0x08
	uint64_t compressed_size;       // 0x10
	uint64_t uncompressed_size;     // 0x18
}; // Size: 0x20

While offset, compressed_size, and uncompressed_size fields are self-explanatory, the flags field packs a lot of information. Below are known flags: 

#define PUP_SEGMENT_ID(x)                   (x->flags >> 20)
#define PUP_SEGMENT_IS_INFO(x)              ((x->flags & (1 << 0)) != 0)
#define PUP_SEGMENT_IS_ENCRYPTED(x)         ((x->flags & (1 << 1)) != 0)
#define PUP_SEGMENT_IS_SIGNED(x)            ((x->flags & (1 << 2)) != 0)
#define PUP_SEGMENT_IS_COMPRESSED(x)        ((x->flags & (1 << 3)) != 0)
#define PUP_SEGMENT_HAS_BLOCKS(x)           ((x->flags & (1 << 11)) != 0)
#define PUP_SEGMENT_HAS_DIGESTS(x)          ((x->flags & (1 << 16)) != 0)
#define PUP_SEGMENT_BLOCK_SIZE(x)           (1 << (((x->flags >> 12) & 0xF) + PAGE_SHIFT)) // Note: PAGE_SHIFT = 0xC

In most cases (ie. "data" segments as opposed to info segments), the segment ID indicates the type of firmware or file to update (see #Indices table). In the case of info segments, the segment ID points to the index of the "data" segment it contains information for. Info segments are typically only seen when the file or firmware utilizes block-based segments.

PUP Info[edit | edit source]

After the segment table is a section that has additional information on the PUP, such as its target firmware and various flags. 

struct ScePupInfo {
	uint32_t fw_ver;                // 0x00 - Firmware version in integer format (ie. FW 9.50 is 0x95080000000)
	char unknown_one[0x14];         // 0x04
	uint32_t type;                  // 0x18 - Beta/Retail/Testkit/Devkit/Proto
	char unknown_two[0x4];          // 0x1C
	uint32_t flags;                 // 0x20
	uint32_t req_fw_ver;            // 0x24
	char unknown_three[0x8];        // 0x28
}

Metadata[edit | edit source]

Following the info structure is the metadata table. These entries contain crypto material such as intermediate keys for decrypting and verifying segments. Each segment should have a metadata table entry. 

struct ScePupMetadataEntry {
	char aes128_key[0x10];          // 0x00 - AES128 data decryption key
	char aes128_iv[0x10];           // 0x10 - AES128 data decryption initialization vector
	char digest[0x20];              // 0x20 - SHA256 digest
	char digest_key[0x10];          // 0x40 - SHA256 digest HMAC key
}; // Size: 0x50

Unpacking Notes[edit | edit source]

  • Encryption is applied on segments post-compression.
  • Non-blocked segments are a straight copy or decompression operation.
  • Processing blocked segments requires looking up the accompanying info segments and parsing the block tables within them.
  • Large disk images and most SLB2/BLS files will be block-based.
