[Galaxy Note 10.1 General] kcrudup:
... that's just it- there's absolutely no guarantee that the modem hardware is the same, especially with the myriad number of countries that the devices (and at least the Note 10.1) have to support.

I build my own OC/optimized kernels for the Note 10.1; in the kernel there's potential support for nearly twenty different modem configurations:

The Note 10.1 (GT-N8000) is "CONFIG_SEC_MODEM_M0" and "CONFIG_UMTS_MODEM_XMM6262", but it might not be the same for the modem at all. If the kernel for the Note2 has been released by Samsung, that would be a place to check as well (at least for the same modem HW type). I just have to be careful, as there's a chance that the modem could end up bricked. I did see that entering the "Magic Phone Number" leads to a different-looking screen, but once I'd selected "Modem" (vs. "PDA") I did see the Modem (vs. adb/MTP) on the USB port (as VID:1519/PID:0020), so that's encouraging.

... that being said, I'm getting my hands on a copy of QPST 2.7.X that'll run on Win7 64-bit, and at the very least will back up my NVItems values and see if they look at all like the ones documented in the other thread, so stay tuned :)

... and I just found out the XMM6262 is an Intel UMTS radio, not a QCT one (so I suspect there's little chance that QPST will work on it at all).

However, that's the same radio used in (International?) SGS3s (see here and here), so maybe if someone has FW for that radio that's got AWS bands, we can use that?

... and supposedly in the Galaxy Tab 2 (GT-P5100), too. This is encouraging that this radio is used in so many popular devices; as this radio isn't so tightly coupled into the boot process, so it might be a simple firmware change and maybe someone's done it already.
