Simple File Manager v0.1 for PS3 JailBreak Arrives

211w 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.

Hey deeanrr, i don't know if here is the best place to post this, but since you posted your osk code here i'll reply here, sorry if i'm wrong.

I'm trying to use it, and it works perfectly on 1.92 sdk (7mb memory container) The only problem is that if I try to open another osk after closing the first one, the application will crash.

I've checked container memory address, to make sure it is getting correctly destroyed by sys_memory_container_destroy(container) and it is. (Also tried without destroying it) The problem seems to be here:

[Register or Login to view code]

that's what crashes the app while the second osk opening. I don't think dialogParam or inputFieldInfo to be the problem, but idk.

I've also tried to memset the text_buffer to 0 before the first/second open, and same results.

Thank you! and sorry for my English, I'm spanish.

I would edit my previous post, but it doesnt allow me to, sorry about double posting.

It seems like the error/crash happens when closing the OSK, not when opnening the new one.

Any clue why this happens?

Take your time and my condolences on that zoned, it's always sad when a relative passes on but is especially so during the holidays.

I have found a couple of bugs in the program that will be fixed in the next version.

Nice work!

Hey Dean I sincerely hope you can incorporate visuals for audio! You would go down in PS3 history (not that you havent already)

I wish it was possible to port AVS from winamp.

Is it possible to copy video-files from Blu-Ray movies with this file manager? I have tried the ftp-servers, but I can't find the video-files. I don't have my PS3 here right now, so I haven't tried the file manager yet.
