1- Only original utility discs can install drivers to memcard.
2- Modchips like DMS3 can cause disturbs to the CDDVD controller chip and it's needed to encrypt the data to the memcard. Even a origa can disrupt this process.
3- SCPH-15000 will not allow the install of a v1.00 driver and will also refuse to use a already installed to memcard v1.00 driver.
I presume your disc is v1.01.
The only solution is do the install with the modchip disabled. Also check if your disc is too much scratched (you probably used it as bootdisc for old doorswap mod, right ?)
Polishing the disc with toothpaste or Brasso can help you to get rid of scratches ...
You can also try to open and close the CD tray when the progress bar is full and it looks like it crashed.
Be sure to try this all with the DMS3 in disable mode ! And you will not suceed if you are trying to use a copy of the Utility disc.
