Downgrade BD-D5300 or patch exeDSP

Post by kszosze »

Dear friends, I was trying to make a Firmware downgrade from a 1030 version to other without the Cinavia protection, following the instructions at the forum. It doesn't work for me, so I try the funny method, patch the firmware by myself, that's no problem for me, so I downloaded the las oficial firmware for my BD-D5300
http://downloadcenter.samsung.com/conte ... M53BSP.zip
unzip into a folder, download the Samygo Firmware Parcher.py and try to decrypt it following the instrucctions. It doesn't work, it gave me that message:
SamyGO Firmware Patcher v0.34 (c) 2010-2011 Erdem U. Altinyurt

Firmware: B-BRCM53BSP v1030.0

AES Encrypted CI+ firmware detected.
Processing file exe.img.sec
Decrypting with AES...
secret key : A435HX:d3e90afc-0f09-4054-9bac-350cc8dfc901-7cee72ea-15ae-45ce-b0f
5-611c4f8d4a71
Decrypting AES...

Decrypting with XOR Key : B-BRCM53BSP
Crypto package found, using fast XOR engine.

Calculated CRC : 0x5BD0D93D
Error on Decryption
So I try do download the svn code and try with another versi?n, same result. I think may be a problem with getting the real CRC code. I'm not a Pyhton developer, almost nowadays, so I think I can fix.
Taking a look at the source code I don't see (I think) suppor for that firmware version (B-BRCM53BSP) isn't it?
So, it could be posible get a new versi?n cover that firmware version, or, if can't, how can I get the necesary info to make the improvement?

thanks and sorry by my bad english.

we don't know firmware decryption key, that's why you get error. No key, no support.

Yes, if you somehow get root access to device, then yes, we could make dump of firmware (decrypted sure).
