Firmware Decrypt

Trying to decrypt FW, but got this:

Any idea?

[juusso]

bug in script while de-xoring? No xor key used.

edit:
@arris69
wrong aes key used. Isn`t?
oh yes, just checked and here is no B-FIR... inside.

@greenhorn, sorry, you cannot decrypt this firmware using samygo patcher. To feel better, try this:

SamyGO.7z

I just tried, but got this:

Yest, thats the truth:

Secret AES key cannot be calculated in this version of SamyGO Firmware Patcher.

Where did you download this firmware from? for what bd model it is?

I you need to look into bd firmware, you can use latest samygo patcher (updated today) and any other B-FIR* (FIRURDEUC, FIRBP7WWC and other) firmware, except B-FIRBPEWWC, because it is E series BD player firmware and we don`t have aes key for this (yet.)

[greenhorn]

It's bd-e6100. I downloaded the fw from:
http://www.samsung.com/uk/support/model ... oadName=FM

@juuso
Can pls share all firmware ver that you have about B-FIRBPEWWC?

[juusso]

I just have v. 1007.0. That`s all.

EDIT: here is the link. But i`m sure you can`t install it normal way.

[greenhorn]

ok. hope it works.

Hi,
I am also trying to decode the blu-ray firmware to learn a little more. In my case it is BD-D8900 firmware (B-FIRHRDEUC). The previous samygo patcher didn't work at all. However I managed to modify the latest one to make it run. When I run the script with decrypt_all parameter, the three files exe.img.sec, Image.sec, rootfs.img.sec all finish with CRC Validation passed.
But, when looking at the contents of the decrypted files, only Image contains some readable text strings, the other two exe.img and rootfs.img have no readable text.
Am I missing something? I presume that the images are some kind of filesystem images and therefore I expected some filenames to be readable.
