Hello. After lots of rooting, ROM flashing, and all that good stuff, somewhere in the process I did something that must be keeping me from using 4G. When I turn on my 4G antenna, in settings it just says I'm "Disconnected" and when I scan for service, it scans for maybe five seconds and goes back to disconnected. In the settings, all three fields for 4G network information (Network provider, Signal strength, and IP address), are blank.
I used wimax_mtd and ls /data/misc/wimax/ to make sure I still had my keys, and I do, they match what's written on the back of the phone exactly. I tried this with no luck.
Anyone know what is causing the problem? I'm running a fully rooted gingerbread.

What rom/version? What provider? What troubleshooting steps have you taken?
Sprint. The ROM is just a rooted version of Gingerbread (2.3.3). The software number is 2.76.651.4. Troubleshooting? I don't even know what you're asking there. I have my keys, I've confirmed that. I tried one thing from the thread I linked. I can't connect. What else am I supposed to try?

Flash the new radio/wimax radio, update profile/prl/twice/reboot twice, tweak ##DATA# settings.

Unless your actually connected Network provider, Signal strength, and IP addresswill appear blank when you look in settings. If you've confirmed you have your keys, and are in a 4G zone. Then you can try a simple trick that sometimes works. Put the phone in Airplane mode for a few minutes. Then take it out of Airplane mode, and try to connect to 4G. If that doesn't work then go ahead and update the radios as VICODAN said. That should solve the issue.
Still no luck
I just tried all of those steps, besides the airplane mode one, with no luck, but I'm trying the airplane mode idea right now, and if that doesn't work, I'll elaborate.
EDIT:
Okay, no luck.
So I went through and flashed the newest radio and the wimax radio, and in the process I realized that I didn't actually have the newest radios beforehand. (I also learned that I hadn't yet formatted my microSD card to FAT32, so it's good that I realized that too. ) After that, I went into System Uupdates and updated Profile and PLR, then I rebooted, and I did it again, and I rebooted. You said to do it twice, so that's why, but you said twice twice so I wasn't sure which part to do twice. (Wow, that was a mouthful.)
After all of that, I tried the airplane more thing, with no success. I've connected to 4G in the past here, and the spring website even says my area has 4G coverage, so I know that's not the issue.
Also, about the tweaking ##DATA# settings, I mentioned that I tweaked it according to the link I put in the original post, but is there anything else I should try?
Thanks for the suggestions so far.

Last thing to try is ##rtn#, wipes fone and resets to factory defaults, then do hands free activation.
Also make sure your [email protected] stuff is configured properly. This is also somewhere in ##DATA# settings.
You can also try flashing a different rom like CM7
But before you do that call sprint tech support and tell them to fix it. They might be able to do something on their side.
Okay thanks, I'll call them later today.

So I called, the woman had me do a few things, and after hitting restore from the menu in ##DATA#, the 4G is behaving differently. Instead of scanning and returning to disconnectec, it now goes to "turning on ..." Then to "turning off ..." And back to on again. It cycles forever, until I manually turn it off.

Well it sounds like something is still wrong. Try flashing a different Rom to rule that out. If that doesn't work, and having WiMax is a must. Then you may want to think about running an RUU back to 2.2 stock. Then just start the whole root process all over.
ok I tried download new UL2 modem I follwed dirrections first off NO ltw (maybe not in my area) but 4g icon only 2nd my download speed like .15mb
then I reflashed the UL4 modem one comes with now I get decent speeds but seems cut off a lot.. this isn't huge issue as I use wifi at home but when im out and about (which havn't tested yet) im not sure.
now I did follow UL2 let modem direction wondering if changed setting RAT setting shouldn't have... if u reflash modem to rat settings go back? when flashing modems back forth I read you delete Dcache and cache which I did but am I missing something? something else do after or something... thanks
when downloading with just network it cuts out stops in middle of download ... i dunno what deal is anyone else got info on this? if I reflash a modem back do i need fix permsions?
well i flashed orginal modem working alright guess thought icerom have better donwload speeds but wow its slick and clean looking I really like it :O) yaaaa
I had no issues with the ucld2 radio while I briefly tried it. I'm going to be honest a say u don't seem experienced enough to be messing with the RAT settings of the radio, and should leave the default settings alone. On first boot after install dial *#2263# and set to auto, then menu > end, and reboot.
Make sure your apn is set correctly, especially if you are with rogers. Using the ltemobile.apn with the skyrocket even in an area without late results in data drop outs, as the phone searches for late signal. Same goes for AT&T. Make sure you are using 3g apn values, which will work fine for 4g.
I'm having the same problem. I tried Sky ICS 4.2a, then 4.2a-8, then 4.2d, and now 4.2a-9.
I've been using UCLD2 on these and had no problems, until today when I installed 4.2a-9 and all of a sudden I can't stay on LTE more than a couple minutes. It drops down to HSPA and drops the data entirely. I've NEVER had this problem, and I've tried every radio there is. I flashed back to UCLC4 and I'm still having the problem.
I'm searching the forums for a fix right now. I might just wipe again and start over with the base/modem.
EDIT: I've tried changing the RAT on both new radios by pulling the SIM, setting LTE/ALL, then Automatic. No change.
Sorry if this has been mentioned before. I did extensive searching without finding anything before posting.
I have been having some very strange data connection issues with my Verizon S3 running BoneStock v3.3 (awesome rom BTW, much thanks to andybones and all contributers) over the past few days. Starting a few days back, my signal strength and transfer rates while at work were much lower than normal. While investigating this, I found myself exploring the settings menus (About Phone > Status and More settings > Mobile Networks) to investigate the signal strength more often than normal (and I believe it had been the first time I had ever been to the "Mobile Networks" view).
This morning, I noticed that I had a 3g connection only at my house (this is unusual as I normally have a very strong 4g connection at home and a pretty decent one at work). Toggling in and out of airplane mode, or rebooting the phone would result in a 4g connection for about 1-2 minutes or so before it would again drop back to 3g. Using the Speedtest app, I would get about 0.5Mbps or so down, and the upstream test would not even finish before showing "Network Communication Issues" and dropping back to 3g. Additionally, my phone has been running really hot and the battery has been draining much faster than usual. Meanwhile, I had ruled out a regional network issue by testing my wife's iPhone 5, which was maintaining a solid 4g connection while mine was dropping.
While Googling for this issue, I ran across lots of articles/discussions referencing the bad OTA update Verizon sent out back in June. It struck me how perfectly the typical list of symptoms for that update matched what I was seeing. However I couldn't see why my phone would be having such similar issues, as I never received that OTA update before flashing BoneStock, and have had weeks on BoneStock with no problems at all.
Just for kicks, I switched the "More settings > Mobile Networks > Network Mode" to "Global", then switched it back to "CDMA/LTE/EVDO", then rebooted the device, and this has apparently fixed my issue!
To be absolutely clear... the current setting for "Network Mode" was already set to "CDMA/LTE/EVDO" when I checked the setting. I merely switched it, then switched it back. That was 2 hours ago, and my connection has been solid as a rock since then and the phone temperature and battery life has gone back to normal.
Doing more research, I saw that apparently the bad Verizon OTA update configured "Network Mode" to "Global" by default, and that many had fixed their connection issues by switching this to "CDMA/LTE/EVDO". Sounds very similar to my problem, except my UI was not showing that it was currently set to Global.
So, hooray that it's working, but I'm not sure what I did or how it was broken in the first place. My working theory is that the phone's Network Mode was actually set to Global somehow through some other mechanism but the UI was not displaying the setting properly, and by switching it and switching it back I overwrote that setting.
Does this ring a bell for anyone? I'd love to figure out what exactly happened, and hopefully prevent someone else from going through the hair pulling that I went through. Thanks in advance!
Hi All,
I've been having an issue after upgrading from a Nexus 4 to Nexus 5 where the phone will not re-connect to the home network (or will only reconnect to GSM with no data) after losing connection. This happens for example when going into an elevator or parking garage; I'll lose signal and when I get back into a signal area it won't reconnect unless I go to the "Mobile networks" -> "Network operators" menu and select "HOME" or "Automatic Registration". I'm using Straight Talk wireless with an older T-Mobile SIM (before they switched to only AT&T). I've called Straight Talk a few times to try and debug this, but the only instruction they've given me is to reset the APN and set it up again, which I've done a couple times to no avail. They claim that the SIM card is good on their end. Any ideas what might be causing this?
Thanks!

It sounds like the Baseband/RIL problems I had with my old LG OP2X with non-stock roms. For me, it was fixed switching to aeroplane mode and back, it could also get stuck there, I remember it once took me half a day to get it out for I didn't want it to wipe it.
Any way, may be it's not the same but it could be fixed flashing a baseband, I think I saw a thread about it somewhere around... Also, flashing the full firmware should —if it's not a hardware issue— solve the problem without doing much research.
HI

Hi Were you able to get a solution for this, My nexus 5 does not connect automatically to the network, it works only for manual search.
Please help...
Same problem here. Any solution?
I'm stuck with out any connection for the las two days. Tried removing battery, airplane mode. manual search. nothing.
Tried my line in other phone and it worked, other line in my phone and it didn't.
S4 I9500. Paranoid 4 Beta 4.
I don't have a really good solution, i reflashed my phone to stock and it did not fix the issue. I ended up switching carriers to T-mobile and haven't seen the problem since. It seems it was a SIM or network problem like i suspected

I still couldn't make this work I'm this close to buying a new phone... any idea?
As stated I'm using the LG G5 H830 T-Mobile variant. I am getting 4G LTE data connection and everything runs well (Not in any WiFi range) Yet for SMS and calling as well as mobile hotspot I get "No USIM card' error. This happened after wiping the system and formatting data. Rebooted recovery (as per instructions on forum) then installed the stock firmware & Patch with systemless root and xposed. After this I did factor reset when just pulling the sim didn't help. Still nothing. I reflashed just the stock firmware with TWRP and SuperSU and issue is still happening. I've disabled rebooted and enabled the phone radio. SIM is in good condition and tray as well everything is SECURE and should be good to go.
I'm assuming a new SIM might be a solution. But I'm not counting on it and with Labor Day tomorrow for me I wouldn't be able to pick one up for 2 days. So here I am...hoping someone might have a fix. I know I don't have many posts on here. But I am an experienced user....just not with the more basic of problems I guess
Thanks!!
Has anyone else experienced this yet? I'm just curious...I had it fixed for a couple days. I've formatted data and done complete system wipe. Tried it resetting phone with the COMPLETE zip and TOT using LGUP. I'm receiving texts. Not calls. Not able to send either. I've activated new sim, didn't help. LG support just told me to look into warranty. T-Mobile needless to say just wanted. Sim card does show stock tmobile short code contacts but phone number shows as unknown. Hotspot won't work. I've tried setting the phone number to the sim. Nothing.
Anyways. I don't think I messed with anything, even so I've done everything to start the phone from scratch. Going to replace it, just more or less curious at this point and maybe others have had the same issue.
I believe I had the same issue as you and it was driving me crazy. I was constantly wiping data, system, etc but my phone kept giving the message "roaming indicator off" where it should show the name of the carrier. This resulted in me having LTE data and that's it- no 3g, no phone calls, etc. I couldn't even access the mobile network menu.
What ended up causing the issue was the network mode setting under wireless networks. Keep in mind at this point I'm running a patched rom which now gives more options in the network mode menu than the phone came factory with. I have an area at work where I have to switch to 3g, GSM/wcdma preferred network setting, because although I have full LTE signal, my connection goes dead. When switching back from 3g I chose the setting lte/CDMA thinking this would force my phone to stay in lte mode due to another area on an upper floor where the phone will constantly drop lte.
Anyways this resulted in my phone saying roaming indicator unavailable, the inability to make or receive phone calls, and either the mobile networks or network mode menus being grayed out. When stuck in this mode there is no way to put the phone back into the standard "GSM/wcdma/lte" mode. Even a complete reflash won't fix it. I even used lgup, which worked for maybe a day until it force closed the phone app and went back to roaming indicator unavail. I wiped every partition and even reflashed radio firmware. Nothing worked.
What ended up fixing it was using an app called v10 hidden settings which allowed me to access the network mode menu directly and re-choose the lte/wcdma/GSM setting. Incidentally on first access to this menu through the app there are only two network settings available. Once you choose a GSM setting, the rest appear.
I'm not sure if this was your issue but I hoped this helped because this took me about a week to workout.
