This is the newest radio for xt907. 98.18,94. fresh from the newest SBF file. This is a flashable zip, if you want only the NON-HLOS.bin, unzip it. Let me know how this works for you.
to use fastboot, make sure you have fastboot or moto-fastboot in your $PATH settings. google this if you don't understand, then unzip and navigate to the unzipped folder, hold shift, and right click. then choose "open command window here", then type: mfastboot flash modem NON-HLOS.bin then, optionally, to give you a factory fresh modem do: mfastboot erase modemst1 & mfastboot erase modemst2 mfastboot reboot that's all you need to do. the commands to erase modemst1 and modemst2 just erase some cache i believe that the modem deals with. it's not manditory, but it can't hurt. if you're using regular fastboot just erase the "m" from my commands, using regular fastboot will show some errrors saying the files are too large, but they should still flash in my experience.
