I am lost trying to downgrade my HT d6750w firmware

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.

I hate to be keeping asking questions but this is what happened:

- i got the exeDSP from the directory

- i open the file in a hex editor just as instructed

- but i look for the string 10 80 BD E8 08 40 2D E9 04 00 50 E3 00 F1 9F 97 3F 3F 00 EA to remove the cinavia crap i keep getting string not found.

i have a B-FIR firmware

what am i dpoing wrong ?

Thank you so much

The strng that i was able to find, that is close to what is the wiki is:

10 80 BD E8 40 2D E9 04 00 50 E3 00 F1 9F 97 0C 00 00 EA 3C



should i modify this one? if so which values to change and with what? Since this is different from the values that are in the Wiki:
10 80 BD E8 08 40 2D E9 04 00 50 E3 00 F1 9F 97 3F 3F 00 EA

EDIT: i am using xvi32 as the hex editor

Thank you for your reply juuso,

The firmware was downloaded using samygo DNS trick. it is the 1116 version. But i dont know where i can see the full name. But according to samsung this is a FIBR type firmware.

How can i be sure ?

I made small tool for windows. It searches for string and makes patched exeDSP. 18 bytes should be written as result. If you get more (for example 36), then means, string is found more than in one exeDSP address - not sure about result, don`t use such exeDSP. If 0 bytes written, means string was not found, binary not patched. Btw, i changed wiki article and from now one, but longer string, updated by Chorloser, is left.

Code: Select all

08 40 2D E9 04 00 50 E3 00 F1 9F 97 ?? ?? 00 EA ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? 06 00 A0 E3

p.s. don`t worry if patcher freezes. It makes job and let`s you know about result

you are awesome man. IT patched 18bytes so i should be good.

Now i am abt to go through the installing part. For CHMOD part can it be done using filezilla FTP client? since i can change the permissions that way, or does it have to be through netcad ?

Again thank you very much juuso for your time and help
