How to prevent the CC to update your firmware.

[usbbdm]

If you decide to use one of the firmware from this site and the CC keep on erase your firmware with different one, please read this.

Each firmware download from this site was based on 07.93, but each CC has different signature, if you find this, go to the end of the firmware, in 07.93 case, address $a584a, compare the one that your CC provide, change it to your CC will work.

Command. (After your CC update your firmware).

Code: Select all

reset 1
init
getram 400000 100000
d a5840

(Write down the string start at $a584a, until it ends at around A5856).

ldram 400000 (firmware you want to program, eg,SPILog0793.bin)
flshdct 400000
d a5840
(write the value you have written down).
program 406000 aa000

The last string I believe is a signature and it is different from CC to CC, this afternoon I helped one member fixed his problem when he wanted to use SPI log firmware but the CC keep one update the firmware.

there is a easyer way working 100%

nvram change emm id to 0003.........

in DCT2000 and older is at the ennd of nvram......

in 700/2500 is at 9801b460 change from 0001 to 0003........ make sure you program the applications and plat first then setram with the emm id changed and will no longer update...

where is emm id located in 2244 in nvram cant seem to find it at the end or anywhere else. I am trying to enable vod and this should fix my box for this to work. Any help would be greatly appreciated.

Can this work with the dct700? If so, please tell me in more details, how to accomplish this, because i dont wish to get any more updates from my CC

usbbdm, this is the information I get:

From a584a to a58456 I get:
..0-8-0793...
So the actual data is 0-8-0793.
This equates to 30 2D 38 2D 30 37 39 33
When I search for this string in the NVRAM.bin and Code.bin, I get many results. Should I also change these values?

[usbbdm]

I think this is kind of signature, I have not played with those number in NVRAM. In DCT2224 I changed firmware that "checks" and bypass it. It is not complete yet.
It is better to have the firmware in sync with CC end. But at your will (meaning you might wish to block the upgrade automatically but to upgrade manually).
