The operating key is still 8 bytes as it was before, and as far as I know the 8 byte key in use has not changed for some time.
In addition to the 8 byte Op Key, TPScrypt also use a 16 byte AES key which has changed many times in the past few months. You need both the corrrect AES key and the Op key to clear TPScrypt channels on id 007c00.
Since I put up my original reply above TPS channels can now also be cleared on the via2 ID 015000.
Read all about the via2 Gold file in this thread:
The AES key changed again on 26 April and it will probably be changed by TPS every few days from now on. Trying to keep firmware patches up to date is likely to be a pointless task from now on. Use the via2 file as I advised earlier.
