And updatewp's own log, it's in spanish (native language) but easy enough to read (or use translate.google.com)
Those .ulz files are opened with USBlyzer. They have a fully functional trial version. Sorry for using proprietary software but it was the only fully working solution I found that worked (and don't want to be messing around passing all this through ethernet to sniff it with linux wireshark): http://www.usblyzer.com/
I tried to open your usb-sniffs, but it failes, cause my usblyzer is ver 2.0 Build 25 and reports, that your files are older, unsupported version. Which one do u use?
BTW: Did not have the chance (and time) to sniff the second part after reboot yet. There is a difficulty to manage the device change, when the nokia boots into the service mode. USBLyzer doesn't care about the newly created device and I'm not fast enough to change it to sniff that device, so I did not get the first handshake pakets, which are so important to get (possibly) the cert and private key that decrypt the mtpz-session.
BTW2: Have a crazy thought: What would be, if the encryption of the snapshot made by zune before update, is only the encryption done by mtpz, nothing more. Then it should be as simple as to find the encryption scheme and parameters of that encryption process to decrypt such a backup to original data stream and store into a imgfs-partition. If further a tool exists, that can extract files from that imgfs-partition and rebuild it after changing something (something like OSbuilder, enhanced with a feature to extract and rebuild the "user"-part of dumps), you should be able to change any file in that backup, which does not have a signature. The (offline in backup) stored registry-files shouldn't have a signature, because registry is dynamically merged from different parts at runtime, and changes with any newly installed app. so interop unlock could be possible and also the restore of all settings, app, mails, sms ... all in one. What a dream!
