My gnex is Running with baseband XXLH1 and im usin a D1 (Telekom/congstar) sim-card.
And my connection is a very low... :(( wich baseband do u prefer for germany??
Upgraded to Jelly Bean 4.1.2 using Wugfresh's excellent Toolkit.
Stock baseband that came with the Wind GNex was Android 4.1.1 running UGLH1. After upgrading to 4.1.2 Stock Yakju build, the baseband changes to XXFL1 - which i assume is the same version as ICS.
So far seems reception is fine.
I'm having issues with my Gnex. I has posted a query regarding the same

The baseband stopped working on a virgin phone (except OTA updates). So I tried flashing factory images just to try my luck.
