Followed this guide exactly to the letter for 4 different customers L720's, NONE of them have been able to get H+ with T-Mobile, AT&T, or StraightTalk.... I ALWAYS just have to show them that voice and texts are working, and hope they don't notice the "E" for Edge/2G........ Don't understand what I'm doing wrong since I've done it multiple times taking my time and following each step exactly. When they text me later asking about it I have no choice but to lie and say the Sprint phone isn't capable of using the other 3g/wcdma bands..... :\
Selecting WCDMA All results in no bars and a red x
When I change to GSM All and reboot, there's instantly service............ 2G
Even told one person E meant Excellent
Then again, shops charge $70 to do it here, and I've hooked them up for $25
