I d/led this firmware update earlier @ 1x, took well over an hour to d/l and install... For reasons not to be mentioned (my bad) I had to re d/l...This time with LTE OnOff and the radio button checked for CDMA only. Once the software update appeared and the counter/timer starting counting down to 0 and the firmware update started d/ling I went back to LTE OnOff and checked the CDMA auto (PRL) and nothing happened immediately, while watching the progress bar after about 5 or 6 secs I noticed that the speed on the progres bar had started moving significantly. D/ling @ 3G, the entire process of d/ling the firmware took about 4 minutes. It took longer to install than d/l... I would have selected CDMA + LTE/EvDo auto, but out of range for 4G by about 20 miles...
