For some reason I cannot connect to 3G. I can only get 4G or 1x. I've been running cm10 for awhile and I've switched back and forth between different ROMs including back to stock and other TouchWiz ROMs. I've not really sure when this happened because I didn't really notice at first, seeing as how I'm in a strong LTE area. I've tried using phone info and using the settings in cm10 under mobile networks. The strangest part of it is that in phone info, if I set it to EvDo only, my bars go empty.
I've updated to the latest modem, and like I said, I've tried different ROMs and even different kernels. I've used Odin to get all the way back to stock unrooted and everything. I can't figure out what could be causing this.
I lost my IMEI weeks ago but got it back so I don't think that's the issue.
Any help that I get can get would be really appreciated.
Thanks

Hello XDA,
I've been having problems with my Nexus S and I've tried everything I can think of to fix the problem but failed. Just wondering if someone would be able to help me.
Background:
I was using ICS Brainmaster's Koush version. I've been following the ICS builds since Drew Garen's SDK port. Then onto Kwiboos then I was flashing which ever ones I could get my hands on. Never a problem with installing on top after clearing cache. I had tried full wipes when I had problems but I installed v4-6 on top of the previous build.
The Problem:
So on the latest Brainmaster's build, one day I was low on battery so I turned on 2G networks only (not the first time I've done this on this rom) and proceeded with using it. When I was able to get a charger I tried to switch my 3G back on. At this point I could not get onto 3G anymore. Only edge. I tried toggling airplane mode, reboots, and playing around with the *#*#4636#*#* settings. Doesn't work.
So I gave up trying to fix my ICS rom and was thinking a full wipe would help. So I did a full wipe and installed the latest Brainmaster's rom (Koush ver). My memory fails me a little bit now but from what I remembered, on reboot I only had EDGE still. I tried Kwiboos ICS rom same thing. I tried Koush's b11 version same thing. I even tried a regular CM 7.1 rom and still no 3G.
At this point my phone isn't even connecting to EDGE anymore as well. I wasn't sure what was making it worse or what was fixing it. I even tried switching radios to the newest radio for i9020a and also reverted back to my stock radio for i9020a. I even tried the XX radios like the KD1 (the one I was on before all the problems) and the newest one as well.
In the "About Phone" section it shows that I don't have a network at all. When I try to search for networks I cannot see Rogers anymore but instead only one weird network 302490 (it stands for the Wind Carrier network).
I give up and hope that XDA has some ideas for me.
TL;DR
what I have tried
-Wiping does not help
-using different APNs (Rogers has two APNs)
-using different radios
-using different roms
-I even switched my sim card to my sister's NS and confirmed my 3G still works. I also tested my 3G on an Atrix and it works.
-restoring to an old nandroid didn't work
-playing around with the *#*#4636#*#* didn't help (like switching to GSM (auto) WCDMA etc, AND changing radio bands to USA)

isnt the KD1 radio for the 9020t not the 9020a? thats my favorite radio to use with my 9020t on tmobiles network.
there is a KD1 for all versions I'm pretty sure. I was using it for the last few weeks with no problems anyways. I switched back to the ones specific for i9020a as well but it didn't help me
Edit: The radio used from this thread: http://forum.xda-developers.com/showthread.php?t=1116884
"Radio for I9020a/I9020t/I9023
Radio JK1/Radio JK8
Radio KB1
Radio KB3
Radio KD1
Radio KF1"
No one has any idea? Simms22?
If not I think I'm going to restore, lock, and try to get a warranty from Rogers..
First make sure you have setup your gmail over wifi. Pull the sim out. Keep rebooting your phone(this can take a while) until it says no sim card at the lock screen. Pull your cover and slide your sim in while its on. The put it in airplane mode and turn airplane mode off and it should connect.
You may also want to try toggling airplane mode on and off between reboots. Sometimes the airplane won't go away when you do this until you reboot, don't worry about that. I've also had better luck getting this to work while connected to Wi-Fi.
I'd also try to minimize kernel flashing after you get it working, it usually causes total network loss again when you wipe dalvik. Putting you back at square one. Also be patient this can take a while. I'd also minimize reboots as they can force total network loss as well.
Also I've already sent my phone in for this issue and Samsung rejected the claim stating there was corrosion due to water damage. But magically all of my water indicators are still white.

This started on the eternity rom, then I switched back to CM7 by thundershed 1.4, then 1.5 and tried various radios on all roms. 4G signal will not stay and once it is lost it will not come back even after switching radios. I have checked the network mode settings. I am leaning toward believing this is hardware related or network related as those are thoe only variables I cannot experiment with. This is happening in Utah.
EDIT: installed stock .9 rom and still no 4G.
having the same issue except it happens in 2g/3g also...
Anyone have any idea cause this is annoying... rebooting the phone temporarily fixes it for me.

A Little Background. When I first got my device I used the kexec method to flash a unofficial CM mod and lost my IMEI. I manually injected it back into my phone and flashed back to stock.
Now, I constantly lose my data connection for 15-45 seconds all the time. It happens intermentantly and is driving me nuts. Is there any way to fix this?
Thanks in advance.
Try flashing another modem, for me when I had the G1 modem it dropped data quite a bit. But try all the ones you're not using because some modems seem to work better for other people.

Change apn from ehprd to lte and it will change you're signal from enhanced 3g to evdo rev a witch Is standard 3g....
I don't have lte near me and has tremendously helped my 3g signal to stay at the signal level my iPhone 4s is being a pure 3g phone....

Thanks for the feedback. I will search the forums for direction on how to do these things.
So when I first got my phone the APN was set to EHRPD, and I just checked (1 week later) and it's now set to LTE and I never touched it and I am running full virgin stock out of the box... is this normal? Does it auto-switch?
I hear the modem might be an issue for a little while...hopefully devs get it fixed soon.
So are people having better luck on the F2 modem or the G1?
After reading the forums in more depth I guess lots of people are having this problem.
Hello everyone. I was hoping that some of you that are more knowledgeable about this stuff could help me out here. I recently flashed from CM 10.2 to KitKat (4.4.4), which everything went smoothly for the most part. However, I've noticed that my phone constantly has no service. I should probably state that I live in an area with very low service to begin with, but prior to the flash I was able to get at least a bar inside my house. Now, I'm unable to get anything.
The first thing I could think of to check was my settings in the phone. The data is enabled, CDMA Roaming mode is set to automatic, CDMA subscription is set to RUIM / SIM, and the Preferred Network Type was Global. I wasn't familiar with the global setting as I was used to seeing the LTE / CDMA / EvDo options there. So, when I clicked on it, it now gives LTE, 3g, 2g, 1x, and Global as options. I tried changing it to 3g, but the changes would not save that way. The only way I could get them to save was to power off the phone, take the sim card out and put it back in, and then reboot and switch them. Once i pick a new setting (which is now set on 3g), it locks it and I can't change it again without removing sim card.
When I look in About Phone > Status section, I'm seeing the network says searching for service. The mobile network type is unknown. The service state is out of service, and the mobile network state is disconnected.
Is there anything I can do to fix this issue? If so, I would truly appreciate any type of guidance you guys or gals could give me. Thanks!
I didn't read your entire post but myself and several others have reported signal issues after 4.4.4 flashes on all different ROM types. I think 4.4.4 is just picky about what firmware and baseband you're running. I flashed a few different RPM packages too but in the end I got lucky flashing the BLK3 modem and it seemed to fix my issues. I had noticeably poor signal strength most of the time and a couple times I would look down at my phone and I'd have no signal at all.
Maybe a dev or expert can shed some light on the root of the issue. I don't know enough about under the hood stuff to make an expert diagnosis.
Edit: The unanimous fix that everyone appears to agree on is to flash the MF1 AIO (all in one) package and then flash the ML1 modem only. Problem is finding a legit source for the MF1 aio package seems to be up in the air.
Like I said though, I didn't even do this. I was just trying all kinds of combinations of modems/aio's/ and rpm's and I got lucky. 2 days now with a solid signal at all times. LTE speeds are blazing too, 45 down and 10 up.
Check ur imei number. Or flash a backup and see if that fixes ur problem.

Can you share the specific steps you took? What worked for you and where can we download it from?
thanks!
About 3 weeks ago after installing the update of liquidsmooth 4.4.4 i randomly started dropping to 3g service in places that i normally had full 4g available. It has slowly gotten worse to where if im not on wifi, than the phone is pretty much useless. i normally have full coverage everywhere. so i originally thought that maybe something had gotten messed up on the update, so i did a clean install of liquidsmooth 4.4, and blackbird kernal and same thing still occurred. also tried carbon rom and slimrom, and no luck. so for the fun of it, i went ahead and reflashed the phone back to stock from backups and rerooted it, updated the modems and reinstalled liquidsmooth w/ blackbird kernal, and same thing. i have went through all the mobile networks settings and tried everything and nothing seems to help, idk if that update screwed something up or if its an issue that others have been experiencing as well, or if im just screwed and my phone phone is dying.... any help is appreciated thanks

I'm currently running OmniToad, and ran CM 11M8 for a short while. On T-Mobile at least, with the custom ROMs it's normal to see H+ only when data is being transferred; it will drop back to 3G otherwise. When I ran the stock ROM on the Relay, it would always say "4G" regardless of whether it was in UMTS (3G) or HSPA+ mode. Apps like SignalCheck or CellMapper will tell you which mode it is really in.
On the other hand, if data transmission is only going through as 3G, it could be a phone issue or a tower issue. Is LTE available in your area, or are they just getting it set up? I know when T-Mobile was upgrading the Chicago area to provide LTE, there were a few glitches here and there.
It was stupid for T-Mobile to brand HSPA+ as "4G" but that's a different rant.

yea LTE has been in this area for quite a while now, i had it with my S4 and it worked perfectly, i never had a problem with the service on the relay either up untill a few weeks ago the internet speed and and data coverage was great, not quite as fast as the LTE on my S4 but it was still more than adequate, i used to use the hotspot and stream netflix on my laptop. now i can usually get a text to send but calls usually fail and if i try and use the internet its impossible. it almost seems like its doing the exact opposite of what it should be doing, as soon as i try and use anything (not while connected to wifi) than it drops coverage to 3g/edge/ or to nothing at all. Im leaning towards the hardware failing side, but i figured i might as well give it a shot and post it and see if maybe i wasnt alone. thank you for your reply.
small note of background on me: first time posting ever in this forum but have been using the tools and roms from it for a long time, so im not a complete noob, but i definitely still have a lot to learn.
