I think you have programed a "bad" backup. Find a good backup and your box should be fine.

There is no separate boot file for the dct2000 stb. Are you sure you have a good nvram backup? The time for the compare looks awful fast, like you have no data to compare. Run the usbjtagnt and use the ldram nvram command and select your backup. Then click on the nvram tab and see if anything is there.

capture your code and nvram and upload as picture. We can tell if it is right or not.

By looking at the memory tab it looks ok. But if the whole firmware has a bad checksum it will reboot also.

For PH7/8/9 you should NOT program the range 400000 60000. Unless it is 100%
compatible.

Program that area might kill the box.
Program 406000 1fa000 should work for you.

You should restore to its original state first before you do so.

debirck works somewhat, im able to ldram nvram setram then cmpram it says ok
then then i ldram code flshdct code and then program code, it starts to go then hang on the first progress bar.


I get no lights what so ever. Only way im able to start anything going is to put the jtag on backwards and getram code, then flip the cable around and reset 1 then works. then im able to all of what i stated above.

Any help would be appreciated.

You should use BDM not JTAG. If you use JTAG it will not work. Never flip the cable if the cable works.

The orange wire from the power supply is "Power Good" line to the reset circuitry. Although I have "Debricked" a few boxes from Flashing 8888's , if the Power Supply voltage on the orange wire is not constant, the box will just go round in circles. Try swapping supplies with one of your good boxes.
