v1.4.6

Disable TDD-only UL MIMO

A new one-way toggle in Disable features. It limits the TDD NR bands n38, n40, n41, n48, n77, n78, n79 and n104 to a single transmit layer — no UL MIMO on those bands — and leaves everything else as it was. It is the counterpart of the existing Disable FDD-only UL MIMO.

It writes cap_limit_rf_mimo, the same file that Disable UL MIMO and Disable Lowbands 4Rx use, so the three toggles are mutually exclusive: turning one on replaces whichever of the others was in effect. After every write the dialog re-reads all statuses, so it always shows which one is actually active.

The band list covers the common TDD bands rather than every one: the file has room for ten band entries.

As with every toggle on this screen, back up EFS first, and restart the modem afterwards for the change to take effect.

Thanks to @h3nnes (#7).

The bundled helper is 1.4.6, matching the app; nothing in the helper changed besides its version.
