Low Signal.. What's the cause?

I'm getting low signal continually, including at home where my other phones always have 5 bars. Half the day today, I showed no signal, and never went higher than 2 bars. I'm having a lot of calls go straight to voicemail.
I'm running the newest prl on El29 with blazer rom. Is this a modem issue, a prl issue, or something else?

Try EK02.

That's what she said...

Signal bars can show anything the manu wants. Just ask Apple....
If you want to really compare, check the dB strength on all your phones and see.

Ya but when it indicates no signal, I'm missing calls.

i've had the same thing today. happened around 4 central time. switched roms figured maybe something wrong on one. found out it was a ougtage in our area. they are working on it.

Try flashing a different modem. FD19 works best for me. Others say EL29 was best for them. Just try a few and always update profile and prl.

on fd02 and kernal is el 29. i even tried stock and still no signal. other sprint users in my area don't have signal either and they aren't rooted

I've been having similar issues in my area lately as well. I've been getting 2/4 bars at home now instead of 3/4 bars like usual. I tried both EL29 and FD19 modems, but still getting the same problem. Also running Blazer Rom.

i'm on tsm revamped

I'm having the same issue.. I'm on alpha 3

Im having a simular problem only get 1 bar of service in my driveway and no 4g at home or work. Has any one made a high gain replacement antenna for the e4gt? Im running a stock le29 thats rooted and clw.
Thanks to the guys here for all the info on everything.

Any updates to this? I've tried 4 different modems and all give me periodic loss of signal, while my evo next to it sits at full strength.

Hows the fe07 modem perform

I'd be running with el29
Currently on fd19
Sent from unnamed 2.0.1 powered galaxy s2 brought to you by sprint

Haven't seen much difference and I been on it all day. 4g seemed to connect a little bit better.
Sent from my SPH-D710 using XDA

MOST modems will perform the same, to be honest. Sprints network is slow as it is, not like flashing a new modem will make a jump in speeds. Its a placebo anyway. With EVERY new modem, the same people will say 3G is better, or 4G is better, or Wifi, Gps, ETC. when in actuality......it doesnt!

Ive had fairly good luck with most of the modems. But today I was not happy with FE07. 4G kept dropping out alot and way too many times 3G was not working. But it works enough to not complain yet. If it goes on for more than another day I will double check FD26.
From EK02 up I can expect up to 15 Mbps on 4G and 500 Kbps to 2 Mbps on 3G. If I see those figures pop up over the course of a week I figure its doing alright. If I have a horrible experience the entire week, crappy performance and never hit anywhere near those numbers then I begin to suspect something. Nearly every modem I have been on had 1.40 to 1.49 Mbps on 4G Upload. When that goes sour on a modem all the time its a quick sign if it persists.

best modem for GPS so far?
Which modem seems to lock on the best with GPS. On EL29 and it isn't very good at all, connects for a while then drops leaving me hanging or won't connect at all. Are they all pretty much the same in this regard? My EVO 4G was really good on GPS.

Samsung devices have not been known for having the best GPS hardware. EL29 is the latest official release but there are several ICS modems available. Try some of them and see how it goes... latest is fe07 found here: http://forum.xda-developers.com/showthread.php?t=1642564

You could brag to your friends about having the latest ICS kernel installed

I like to listen to a streaming talk show on my phone when I shower in the morning. I need wifi to do it, no data at home. Some modems will not connect to my wifi in the same bathroom which is the furthest from the router. Other modems will connect with a strong connection. I don't think every modem is the same.

Well I have had gps issues with all the ICS leaks but I have noticed big differences in speed between certain modems fd19 is a solid modem but fe07 is just as fast for me and my gps actually works especially in navigation and our app places.
The top 3 speeds are on fe07 the bottom 3 are fd19 on 4g
Sent from my SPH-D710 using xda premium

FE07 has been good for me so far. Some of the leaks really crippled my 3G, but FE07 seems to work just as well, if not better, than EL29 - at least for me anyway. Haven't tested GPS yet.

For me, No modem seems to work. I guess I'm plain out of luck. There are no towers near me so my phone ALWAYS(sometimes) fails to send text messages or even make calls.
Anyone one have any suggestions I can try?

You should ALWAYS(sometimes) switch to another carrier.
But seriously, allow roaming if you haven't done so already.

Wouldn't I get charged extra for roaming?

You should be ok as long as you're in your coverage area. I roam all the time and don't get charged extra. I think it has to do with whether you're on Sprint's towers/network or not, and whether those towers are in your coverage area. Might be worth a *2 to Sprint to find out.

Use roam control to force roaming. They will eventually send you a letter telling you they're canceling your account (no early termination fee) due to excess roaming, and you can sell your E4GT and go to another carrier!

As the title says, does anyone know what the best modem is around here? I know it's a long shot someone will reply from Cincinnati but that'd be nice.

Why don't you update to MB1? For some reason LJ7 is lagging and sometimes doesn't turn on the WiFi.

It would be worth it

I've had noticeably better reception over LJ7, but as others stated, 3G is terrible here. Wimax on my Epic 4G was actually pretty good in a lot of areas, its too bad they didn't pack that radio in our S3s.

Glendale huh? lol you live like ~10 minutes away from me

Don't know if you all are still listening but have any of you noticed how much worse the 3g has gotten lately. Over here on the west side, I've been noticing that I'm on 1x most of the time. I finally got around to flashing MB1 today so I'm hoping that is going to be better. Not that I have high hopes at all...

Need help with RIL File..

Can anyone help me with the RIL Stuff on the G Pro? I have service issues in a low service area but ONLY when using a NON AT&T Stock rom. When using CM 10.1 or the Telcel E980h my service sucks! From around -90 to -100 on stock to -100 to mostly -105 to -111 and its terrible! but When on Stock the network is flawless. Yes Ive tried flashing the Baseband still same problems.
So now the next thing to try is the RIL stuff which I DONT have exspeicance with. How do I get to the RIL files to copy them so I can put them on something else?
The ONLY RIL file I found on stock is under /system/lib/libril.so or something like that but that did nothing.
If its the RIL causing problems how can I fix it?
If its not the RIL that would cause that what else do I look into??
I also wanted to add at this location the phone NEVER looses service completely! But when using something other than the Stock AT&T E980 Rom It keeps going to emgency Calls only a lot as well!

Okay so now that I see when you're on CM10.1 its the same low service. Its not the RIL files. Its actually AT&T lying to you. I know this because whenever I go to Rangely Co, I have crappy service on cm10.1. When on stock ROM I see all bars and 4G, yet speeds are almost nonexistent and I can hardly ever get a phone call out

Its NOT AT&T Lying to me. The Data and Phone calls work fine and service stays intact! I`m NOT talking about Signal Bars here I`m talking about the actual signal strength, and the acutal Service. While on the AT&T rom I can move my phone around at the location and will it will occanalny qurik and stop working but still never go out of service (Still on AT&T network) On any other rom I dont even have touch the phone and just switch to Emergency Calls only, I know how AT&T fakes the signal bars on there phones software but this is not the case the service itself simply does NOT suck as bad as it does when NOT running AT&T`s stock firmware.
So Im not really sure whats going on.
The ONE thing about CM 10.1 though the Service NEVER went out and was a good bit more reliable than the international stock roms it is atleast usable! But I never care for CM.

I had the same issue when I had my s3 when I was on cm my signal sucked but when I was on a touch wiz Rom it was fine could never figure it out tried flash in different modems that did not work either
Sent from my LG-E980 using xda app-developers app

The ROMs interpret signal strength differently. That's why I said before at&t stock ROM is lying to you. It happens to me all the time. When I'm in Rangely on the stock ROM it'll show that my signal strength is strong but it actually isn't because there isn't a tower for them there yet it shows I'm connected to them. However on any other ROM it shows I'm roaming.
Its because the ROMs are designed to read differently. That's why I say at&t ROM is lying.

I understand what your are saying, But its its NOT that causing my issue, as when on AT&T Stock Rom, Calls GO THROUGH Data Works almost with an issue! (not looking at the signal bar and such) On the Telcel rom or anything else, Calls Fail, Calls get Dropped, Data just sits there, Phone looses complete service and says Emergency Calls only!

Yea, But that shouldnt do anything as There is NOTHING to roam on here, The closest Place that I have even roamed before and even by Coverage Maps is about 5 hours away Near Nashville, TN but thats the ONLY time I have ever roamed. Sadly even though T-Mobile is here it wont roam no phone has its always emericancy calls only.

So what exact files Should I pull from the AT&T stock rom and put over on the other? whiles the files and folders I should move? Thanks.

Lte signal

Does what Rom or kernel you are using effect your signal and speeds? Sorry if this is a dumb question but my lte is at like 4mbs right now and it was 20 plus last I checked a few days ago. I have unlimited data... supposidly

Generally no. It might affect what codes are displayed (LTE, 4G, E... vs. H+, H, etc) but most do not affect the radio unless you load the wrong ROM for your baseband (xxxxxMDL, etc.). Check settings for APN (can be rom affected) and radio band with *#2263# to be sure.

You can use any modem version on any rom... Your firmware version doesn't have to match your modem/baseband version. That's why people pull them and post them. So you can try each one and find which works best for your location. By testing modems out you can achieve anything from better service to better battery life.
But yeah nobody has pulled and posted them for tmo. I was actually looking just 2 weeks ago. We only have 2 tho. I pulled the modem from my phone which is running MDL but never tar'd it. Was going to pull the other from a tar but download of the tar was slow as hell and my pc shut down (thanks MS for the updates. Perfect timing) and killed the download and never got back around to re-downloading it.
