You should have grafchokolos modules, and patches installed
This works on 3.55 without a dongle
1st step – Generating a challenge
———————————————–
- ps3dm_usb_dongle_auth /dev/ps3dmproxy gen_challenge
2nd step – Generating a valid response for a challenge
————————————————————————–
You need a dongle id. Valid range for dongle IDs is 0×0000 – 0xffff. So choose one, doesn’t matter which one, but some are revoked !!!
- ps3dm_usb_dongle_auth /dev/ps3dmproxy gen_resp 0xBABE “here is a challenge like this 0xXX 0xXX … of size 20 bytes”
3rd step – Verifying response (Enabling “Product Mode”)
——————————————————————————
- ps3dm_usb_dongle_auth /dev/ps3dmproxy verify_resp 0xBABE
“here is the response from step 2 like this 0xXX 0xXX … of size 20 bytes”
4th step – Checking if “Product Mode” is enabled
——————————————————————–
The returned value shouldn’t be 0xff.
- ps3dm_um /dev/ps3dmproxy read_eprom 0x48C07
5th step - Inspect if CORE_OS_PACKAGE.pkg isn´t damaged
_______________________________________________________
ps3dm_um /dev/ps3dmproxy inspect_pkg 1 0x9 CORE_OS_PACKAGE.pkg
6th step - Install coreOS pkg
________________________________________
ps3dm_um /dev/ps3dmproxy update_pkg 1 0x9 CORE_OS_PACKAGE.pkg
7th step – Disabling “Product Mode”
————————————————–
- ps3dm_um /dev/ps3dmproxy write_eprom 0x48C07 0xff
