Sorry to dig up an old thread. I found the NID of cellFsAccess (0x06e681ed) using this program and I've tried the access function by modifying some files in PSL1GHT and in newlib.

However, when ever I try to use the function, it locks the PS3 hard. I have to shutdown and restart. The PS3 will check the file system every time. It's locking hard.

So my question is this. I noticed that the hashes for the missing NIDs where dumped from the sprx's from a 2.30 firmware using Ida. Is there a chance that in the newer firmwares, the SPRX's might have different hashes? Also, does anyone know how to get the hashes manually from the SPRX's? Thanks.
