okay. I've searched for solutions online for 2 days now. its an odd problem. allow me to explain. Ive been able to use my esteem just fine until one day at work it refused to connect to the internet. I can receive phone calla and sms. the odd part is that after placing a call, I get 3g for about a minute. I use that precious time to download apps to help me find the problem. under phone status, it says I'm on LTE, but my mobile network state says disconnected. zero access to the web . I've tried updating my prl. currently on 3026 in Atlanta. rebooted several times, tried lte on / off app, restart connection app, apn apps, quick settings and airplane mode toggles. I've called metro for the refresh and reprogramming. I've done the ##6026* thing. my esteem was rooted before I had problems and still is. baseband ZVB. I have one hypothesis. I installed easy battery saver. it auto toggles your mobile network connection to conserve battery. that's when I would notice my signal change from 4g to 1x. soon after, i couldnt connect at all. I uninstalled it because I did not want my signal being altered. no luck after. I really don't want to factory reset. I've done a lot of work on my go launcher ex. theme. if anyone could throw any ideas, let me know. I've even tried getting a new account on the phone. I don't have insurance. I bought this phone in October on craigslist and its never dropped 4g. my wife owns a Samsung galaxy indulge (which I'm using to post) and shes got full signal and 4g. oh, and I'm kinda glad it happened because I finally joined this forum. I've been a frequent visitor since I got my lg Optimus.
