Latest version of firmware for RX-8200 is 8.5.0 but in some log files that I already sent to Anubis_Ir (+firmware)they mentioned to 8.11 version.That version is not exist and they want to mislead.The big problem is that they didnt use constant keys stored in firmware!! They weekly send new keys and clients must inject those keys into the recivers.

RX-8200 8.5.0 has been analyzed and it doesn't contain the new nano `EC`. It's old and only supports nano EE and ED.
This is the build info of the last version:

I ask my friend who works in one of the biggest company in the world (Broadcasting)about the version of 8.11 ! He told me they have 48 recivers with version 8.5 and work perfectly for EPL feeds.

I don’t understand how do official receivers cope without this nano, oh is this nano used as Some protection layer to protect the real key?

I am guessing this is going to be even more difficult to crack?

Why we don't take up a collection all together to buy an ericsson receiver to dump firmware? :thum:

If there is nothing in the new firmware maybe we are missing something in the EMM stream. I'm sure there where some new looking unsupported EMMS, Could they be loading new information into the these receivers to use the new nano through the emm stream.

Yes looks like one of the new functions includes the insertion of Tandberg Keys sent by the providers onto their extranet.

This is the new `bin\.mdl` file for vPlug (+ full source code) and supports the new nanoEC. You should copy it to vModules folder.
Notes: It requires a DES key and also an AES key (included too, in the bin folder). Without these `2 keys`, it won't work.

So ...
- Good news: we know how nanoEC works.
- Bad news: It requires 2 keys. 1 DES key and 1 of 32 AES keys which won't be transmitted by the EMMs.

Based on the posted image, AES keys start from index 01 to 20 and not 00 to 1F. Use the attached file.
