I am lost trying to downgrade my HT d6750w firmware

[strugler]

Hi guys,

i have a sammy HT D6750w (home theatre) and it came with firmware 1014 which has the cinavia crap.

I followed the DNS trick and i got to download the 1116 patched firmware.

I went ahead and installed the samygo app successfully.

Now, as far as i understand, i downloaded an ealy firmware version 1010.2 (i am not sure if it is the correct firmware) i then downloaded the Samygo firmware patcher ver 0.34, installed pyhton 2.6.3 and crypto (i have a win 64 OS, but installed the x86 version of pyhton and crypto, i a,lso tried the x64 version to no results)

So i followed the guid i try to decript, the drcryption processes starts normally then at the end i get:

Calculated CRC : 0x5b5c3fb6
Error on Decryption

Theere is a.img file that gets created in the destination folder, but i think it might be corrupted. Anyone can help me plz

i spent hours on this

Just want to add that i tried with a Win7 32 machine and i am getting the same error.

I downloaded the firmware from the forums and it seemed like it worked for other people. What am i doing wrong ?

Ok guys im going crazy here.

I just want to get rid of cinavia, i now have the 1116 on my ht d6750w. DO i have to downgrade, or can i just use the cinvia patch using samygo ??? as i said i installed the samygo ap on the player and i can ftp to it.

I am really lost, spent the whole day reading and trying that i am very lost right now

If you can ftp to device, you`re already on patched firmware.

yes, now you can use your custom exeDSP. Not need for downgrade.

How can I do that ? From I can get the file?
Can you please show me how to do this, I tried following the wiki but I'm lost

how do i get the customed exeDSP from my installed 116 (which i installed through the DNS trick, meaning i dont have the files for it to create exeDSP)

i am really lost here.

Plz Help!

You have to connect to TV trough ftp, navigate to /mtd_exe and copy exeDSP binary from there. Further - according wiki article at your responsibility.
1. patching.
2. installing.
