Lock the channel map for 7.93

Post by **usbbdm** » Wed Nov 15, 2006 9:12 pm

Before I make the real function in DCTTest.dll if anyone interested, try this,
load the code (Assume ph7/8/9)
go to address 0044A2A8
Chaneg 6700A4 to 6000A4.
Fix the checksum
program 406000 aa000
Your channel map will be kept. (I am working on the channel mask).

This will be useful for whoever want to play with the channel map. The CC can not update your channel map.

Locking the channel mask has not been success. I will add channel map lock first to all the testing dlls. We can start to play with the data in the channel maps and see if we can do anything. Without channel lock, our channel data will be replaced by CC in less than a minute after boot up.

it updates because some small numbers in nvram...

is the mca numbers. i belive they are responsible for tvguide and automatic update .....how i guess this is by testing like a few months ago cloning area to a diferent area.

in the first 10000 of the nvram ....thats in 2000 models.....i cant find it in 700\2500

same thing with firmware update i stop firmware update by erasing the ASTB blocks.... and firmware dosent update no matter what this is 100% working on 700 too i just tested.

i suspect the mca numbers are another big factor in this process and maibe something else ......but everything that has to do with channels is in the first 10000 off nvram and controlled form there...

again now i know that this works on 700 too havent tried 2500 but i think is same.....2000 models only 7,8,9

how do i gain access to my box, to do these things mentioned? Do I need special software for my computer and then directly connect via usb? My software version is 71.44-1203, firmware 12.31. I do not own this box, does this matter? it is my cable companies but i will buy one to play with if i can be assured it will work. Any help is greatly appreciated.

i apologize, new to this message board thing. What is this thread referring to? Can you point me in a better direction

this thread is about modifying a channel map and stopping the CC from changing it back to the default for firmware version 7.93.

Thanks!
I just tried this (from first message in this thread) and it works!

Once I got the map locked, I changed a channel to a different channel. For example, I did not want shopping channel on ch 10, so I changed map so ch 10 is another channel. It works! I can tune to ch 10 and see new channel I put there.

But.. I need to go back and review because now I have gaps in TVguide data and it has wrong labels for some channels.

So, maybe I did something wrong .... ?

Thanks again, we're getting close! I will be interested in seeing the mod to test the revised channel mask.

Keep up the good work!

Someone want to check this,, I think I figured it out.

Analog channel map entry look like this:
(example)
80 00 00 10 aa bb ch 00 00 00

aa bb = TV Guide TAG

ch = channel (in HEX)

I went back and copied the TV guide tags from the appropriate channels (from a valid local NVRAM) and it worked!

It looks like the same is valid for digital channels. just change the '10' to 00 and use ch plus trailing 00's fill in channel (hex again).

example for digital ch:
80 00 00 00 aa bb ch 04 00 2a

aa bb = TV Guide TAG
ch = digital channel
04 = ?? part of channel value?
2a = sub channel?

Someone care to correct so I can update my notes ...please.

Hope this helps someone trying to do the same thing.

the new numbers in the digital must be the ID

look under curent channel status diagnostic 7

this is great we might be able to add channels from diferent area. i will get into this /
04 = ?? part of channel value?
2a = sub channel?

042a must be the id

or 2a04/
