X-Chip Location (SWAP)
Hi,
Where exactly is the x-chip located on the on the dct2000 PH7 board?
Is it U700, U901, U500
Reason why I am asking is because I want to attempt to swap chips.
Many thanks.

Yes, it is possible to move an ACP without losing the NVRAM contents but it is extremely difficult and seems somewhat pointless since the gain is so small. You would have to use a high wattage heat gun and high temp flux to free and the re-solder it all the while not allowing a single instance of time without the VCC and VSS supply, way too challenging.
The small pads located near the chip are not for programming the ACP. The pads are test contacts of the MPEG stream too and from the BCM7015. This stream is tuned and fed to the ACP for decryption and if the right key is used it is returned as a decrypted mpeg signal. Some of the stream data if returned in the SPI channel e.g Program ID, EMM etc.

sorry for replying to this post I know its old and maybe dead but I need to be clear on the XC CHIP.
Questions!
if I have full backup from wide open DCT then.
1. If I install new XC CHIP can I restore my full backup?
2. can the XC CHIP be programed before install using special tool?
3. if the XC CHIP its successfully install after programing I have to restore back NVRAM & CODE?
replacing the XC CHIP it's possible with the right tools the question is if the new XC CHIP can be clone or if there is no way to program the XC CHIP with jtag or any other device.
Thank You!

I Believe their is an easier way using your usbbdm m.c. I think i saw a program that might program the chip, Its called Turbo BDM or something.....It suppose to use inputed values and find the output values for certain characters that are inputted by the program. I can provide a link if any of you wish to look over the source, since I'm just guessing. I do believe its coded in Assembly.

re
I Will Contact Bdm When I Recieve And Test This Device And I Will Leave IT Up To Him If He Wants To Release To All On The Site As A Security Measure
