== Usage ==


SLB2 files are parsed by many executables:
* PS4 [[Southbridge]] EMC IPL to extract C0028001 (EMC IPL) and C0020001 (EMC IPL information) from sflash0s0x32b (inactive partition).


== Other notes ==
It looks like newer (confirmed for OFW 7.55 and above) SLB2 files have some data between 0x200 and 0x270 which doesn't affect any unpacking tool but affects the unpacking on the PS4. The file gets recognised as corrupted if that data isn't there. This data is present in the `recovery` images but not in the `update` images.
-Other note
Newer updates seems to have  New data exactly before the start of the PS4UPDATE.PUP file
It has the same effect as the  one between 0x200 and 0x270

Usage[edit | edit source]

SLB2 files are parsed by many executables:

  • PS4 Southbridge EMC IPL to extract C0028001 (EMC IPL) and C0020001 (EMC IPL information) from sflash0s0x32b (inactive partition).

Other notes[edit | edit source]

It looks like newer (confirmed for OFW 7.55 and above) SLB2 files have some data between 0x200 and 0x270 which doesn't affect any unpacking tool but affects the unpacking on the PS4. The file gets recognised as corrupted if that data isn't there. This data is present in the `recovery` images but not in the `update` images. -Other note Newer updates seems to have New data exactly before the start of the PS4UPDATE.PUP file It has the same effect as the one between 0x200 and 0x270
