I'm sure I'm just over looking it, but is it possible? My wife doesn't get anywhere near as strong of a signal as I do with my .223 flashed Bionic. She will have maybe 1/2 signal on 3G where I am running strong 4GLTE. This is her second Nexus & had this issue on the last one too, but at least this one doesn't reboot on her several times a day & drop signal completely. I heard that the Jelly Bean radios could solve this issue for her. She doesn't want a new ROM or anything fancy, just a better signal. She also doesn't want to wipe & start over from scratch. I was looking into Wug's Toolkit & I saw where it lists just rooting (not unlocking the bootloader), but it doesn't mention wiping data one way or the other. Can anyone answer this for me? Thanks in advance! tl;dr If I just want to gain root access to flash new radios, do I have to wipe the data? If not, how?
