Stock, which one? (Exact build) same for CM10, nightly? RC? stable?
What recovery are you using to flash? I've had baseband unknown issues with the 184.108.40.206 t0lte TWRP while flashing OmniROM nightlies (yet CM and PACman 4.2 ROMs were OK) whereas it worked just fine with non-touch CWM 220.127.116.11.
What baseband are you using? It may be a matter of updating that. (I have an "unusual" T889V, so I can't give you much specifics on this topic.)
Logcat and monitor.bat are part of the Android SDK, as is ADB.
