has released the first PSP custom IPL, which is an extension of the firmware 1.5 IPL providing numerous features.
Feature for user:
- It bypasses ta-082+ brick, so you can have a ta-082+ without any key patched running 1.50 kernel based firmwares.
Feature for programmer:
- It dumps 0xbfc00000, the psp boot code prior to ipl, to the address 0x883e0000 (which is not touched by 1.50 kernel). To get the boot code in a 1.50 original firmware, just run kdumper, and extract 0x3e0000-0x3effff from the kmem.bin file -> that's the psp boot code. If you are in a cfw, you will have to execute the kdumper as a recovery or autoboot, because the 3.XX kernel overwrites the 0x883e0000 memory.
Note that this ipl is flashed to the nand, not written to the ms.
