Simple File Manager v0.1 for PS3 JailBreak Arrives

203w ago - As a follow-up to his previous work, today graf_chokolo has done it again and posted his code for decryption of PS3 SELF files using appldr.

Looks like he still can't decrypt game or NPDRMs selfs but soon pehaps.

Download: Graf Chokolo PS3 SELF Decrypter PSGroove Payload

To quote from xorloser's blog (linked above): Guys, i promised to you to make my SELF decrypter public. I just uploaded it Let me first explain how it works.

I used only HV calls in my code because i wanted to learn how to decrypt SELFs without GameOS. The decryption and decompression of SELFs is done by isolated module appldr which is prepared and loaded by lv1_undocumented_function_99. After appldr is loaded it sends a message and waits for your instructions to decrypt some encrypted segments. When the message arrives i pass encrypted segment data to appldr through shared memory and it decrypts the passed data. When the decryption is done the payload sends the decrypted data over network to my PC and i capture it with tcpdump

I’m using IDA to analyze the decrypted code. First i extract the decrypted segments from pcap dump and load them at right addresses into IDA. I created a shell script to make segment extraction from pcap dumps easier. Virtual addresses of decrypted segments you will find in ELF header.

The target group of this release are again advanced programers among you. The goal of this release is not to give you a tool for SELF decryption but to show you how it can be done So, feel free to ask me any questions about my code. I will support everyone who wants to port my code and create more user-friendly GameOS applications for SELF decryption because i do not intend to write any GameOS tools I’m more interested in HV reversing.

My SELF decrypter is not able to decrypt games and NPDRMs yet but i’m working on it I think you will have enough SELFs now to reverse

I will document my findings about SELF decryption on my HV page in the next days.

After creating Simple AVCHD Manager - the first AVCHD manager for a jailbroken PS3 - some of the other programs I have been exploring had the requirement for a file selection screen in common, so i decided to create a simple file manager utilising a pointer like Multiman and added some other useful functions.

As this is only version 0.1 it has a few areas that need cleaned up and only has some of the planned functionality implemented.

Rename/Create Directory and other standard file manager functions
Search option
Display text files
Edit text files
User configuration in INI file of colour scheme
