LOS update -- new development

I am currently tethering over a 4g connection, and my internet is working fine, BUT I have a complete LOS for the cell signal. I think this could be a very important fact because we should be able to know some things by the fact that WiMax is working while the cell signal is altogether lost.
Hopefully, with this info, a solution is a little closer at hand.

Ok...when people say LOS do they mean Loss Of Service? Or Loss Of Signal?
Because if its the latter, that sht aint that bad. But if its the former...I'm glad I don't have it.

It is bad. People that get it have to reboot phone for it to come back and it kills battery life. Nit to mention missed calls and texts. It is a complete loss of service.

Its 2 separate radios..

I had pandora going over 4g earlier for hours...but lost signal with a crossed out circle after about an hour. Pandora kept going but u couldn't make a phone call, ths.falls in line with the other poster. Im running eg30plus over latest 2.1 midnight.

As WhiteWidows stated, it's 2 different radios. The LOS people have posted over and over about is the ability to make/receive calls (which is what the OP posted about). The Wimax radio (4G) doesn't transmit phone calls. That's why you can do data on 4G and still make a call at the same time.
.....

Hi guys, this is one of my first posts but I've been a long time reader coming from the Evo 4G forums. I'm rooter using Zedomax v3 and experienced multiple LOS as well.
Last night I tried limiting the clock speed to 1ghz and setting the min at 400mhz. Strangly I now get slightly better reception and never had a LOS yet. Will continue to test out this theory and see if it's clock speed related.
I came about testing this since I ran mine at 1.6 for a while and not only would I get more LOS occurances, I would also get phone freezes lol. I tether and stream music a lot so wanted to keep it slightly underclocked to keep the temps down. Hope this helps as a temporary band aid for the LOS bug

It definitely makes sense that the two radios are separate...the point of my post was just to offer some more information to help figure out a fix.
If one radio fails while the other stays working, do we know that the problem is phone-related? Many posters have speculated that the issue may be on Sprint's end, so I wasn't sure if this info did anything to challenge or support that theory. Maybe it does nothing, though -- just throwing it out there!

Someone posted a log cat of a LOS. There's still some coding in the radio files that thinks there is a sim card. Says sim disconnected and result radio off

Hopefully a solution is found soon, I've seen similar issues posted on various android forums. Androidforums, Sprint community and here. Wish I waited a bit to hear more user experiences....

Has anyone tried editing the build prop to manually change the preferred network from wcdma to CDMA auto? Maybe that'd fix that issue

I have been on my current SGS2 stock out of the box for over a week now and have not had any LOS issues, or missing texts, or data not working, or missing phone calls, etc.....
I have been using wi-fi, 4G, 3G, have an Airaive, went to an area where there is no Sprint service and phone roamed fine and then went back to Sprint service when available.
I have been unable to replicate the LOS issue on my current phone through all possible ways of using it.
My first SGS2 was also fine until I rooted it which then gave me an LOS within 12 hours of doing so.
If someone has a another sure way to get an LOS, I am willing to try it on my stock, never rooted phone but I don't think there are any other situations I can try that I haven't already......

Time.I have went 3 days without a los then 2 in same day.It is all random

4g connection issues

So my phone just randomly stopped connecting to 4g yesterday mid afternoon. I have never had 4g, Wifi, or even GPS issues. Ive been on the stock (rooted) EL29 rom thats posted in the dev section. I have not been flashing different roms/modems/kernels lately. I did flash the EL29 modem again cuz i thought it might be corrupt, no still nothing...
I went back to completely stock rom/kernel/recovery EL29 a month ago and have kept it that way. Havent dropped the phone, no water damage, etc etc.
Ive read a few threads about 4g problems and 1 thread mentioned possible corruption to 4g modem data. Another similar thread went unanswered....
What do u guys think? Has anyone else experienced this??

I experienced this and the only way I got it back was odining a new modem. I tried flashing through CWM but that did not help. It does have something to do with 4g modem data corruption and only odin fixed it for me.

A few more people are also reporting the same problem. Mainly in CA. There are two more threads about this issue.

Thought it was just me. My 4G dropped alot yesterday, and data speeds were SLOW!

I was having 4G connection problems over the last two days; it seems to have been resolved as of today. By the way, I am in the LA Region, CA.

solar storms are happening and affecting us now as we speak people tomorrow theres supposed to be a bigger one. http://www.foxnews.com/scitech/2012...s-still-shooting-out-from-active-spot-on-sun/
maybe this could be affecting wireless communications moderately

Ok people, im in LA too. I just got off the phone with sprint Tech level 2, they have no idea if its a 'known issue' which should be if more people call in and complain....
I was at a sprint store earlier where they spent an hour diagnosing the phone, reflashed EL29, re-provisioned it etc etc....and 4g is still a no go...they did NOT want to swap out the phone cuz they couldn't find anything wrong with it. Their only answer after minutes of argument was: Its a known issue by samsung and we will have to wait on them for a fix........i call this complete BS and basically not wanting to deal with the issue.

I had the same problem. I tried resetting phone. Update prl& profile still the same problem. Flash new Blend ics. Rom. And 4g work. Not sure happened. I lived the west Covina area

Signal Strength on E4GT ICS Is Erratic

My signal strength is jumping around like crazy...from -106dBm then back up to -64dBm...and everything in between, in a matter of seconds. This has been happening since FD24.
I have been using Sfhub's stock rooted nodata roms. I tried the FD02 kernel repack with rougue recovery on FD26 rom & modem, and it seemed to jump around alot less.
Could the kernels be the issue? Or the modem? or the Rom itself?
Update for FF02:
FF02 seems to be better for now...will do some tests later. I had it jump around only once yesterday.

Try throwing your phone at the wall, fixed mine

If it is jumping fro -106 to -64 and back, it is probably scanning because it lost signal. When you first boot your phone, often it exhibits the same scanning behavior.

That's what I figured...and that fact is absolutely murdering my battery life.
You think a data reset will help?

I wouldn't say there is a great chance, but the possibility exists.
The "cleanest" install possible is the following:
1) install Full ODIN OneClick
2) remove external sdcard, if any
3) from android, format internal sdcard
4) from android, perform ##786# reset (providing your MSL, which can be retrieved via "getprop ril.MSL" from terminal or adb shell)
If you format your sdcard, make sure you move your backups to your PC or other external storage.

What does the ##786# reset do exactly?

It resets NVRAM as well as your Android user data.
You dial ##786# in the dialer on a stock rom.
It will reset stuff like your phone #, your data login, and other values stored in nvram.
It will cause your phone to perform hands free activation at the next boot, which will populate that information again as well as update profile and prl.
Hands free activation only works on Sprint's native network so don't do it in a place where you can't reliably get signal.

Anybody else having this problem?

happened to me right after i flashed fe07 modem. i moved back to fd26 to see if its the towers or modem. all seems fine, but i will be keeping an eye over the next day.

FE07 had absolutely abysmal 3G data speeds. It took so long to download the Facebook app update that I immediately flashed an older modem to check against it - FC24 runs like a CHAMP.

I tested fe07 for a day or so. I didn't notice much other than it would drop to 1x often. I ran a speed test 3/4g between fd26 and fe07. Fd26 clearly performed better for me. I went back.

Still rockin EL29 here. All the new modems sofar for me have sukt dik. And YES I let them settle in B4 pulling any test. SOOOO I dont want to hear the BS here, like whatwent on with my other post in a similar topic. Yeah got me sum points taken away..lol..

Updating profile is what's important. there's no settling in. Im using ek02. It's the most stable (IMO)

Try ta tell that to some of the fools in here. Then bam a mod from a completely diff forum or wherever he is from hands me a infraction. Oh well. It is fun to flame. Fuk um.

Lol

I don't discuss modems because for every release 1/3 think it is better, 1/3 think it is worse, and 1/3 think it is the same.
No matter what you say, some people are in violent disagreement.
Just pick what works for you.

Fe07 is the best ever in history until the next best release!

I got the "you roamed too much call" yesterday. I don't force roam ever because I'm in FL and force roam doesn't work here with sammy phones.
I was running several of the recent modems last month and used 5GB of data roaming. Almost 100% of my data. Was the first and only month this has ever happened....in 8-9 years. I reverted back to older modem and roaming stopped. This was on top of the fact that I keep wifi on at all tines at home because my house is a dead spot. I also have an air rave (whatever its called).
I only listen to music, email and surf web. Quite surprised by the call.
I explained to rep that I only go to work and home. That for whatever reason home and work are dead zones. Of course he checks and tells me coverage is great in my city. Then he says sprint can boot me, or I can ask to switch for free. Told him I didn't want either. His solution was for me to put setting for roaming sprint only. I asked him how I would use my phone if I only roamed sprint? No answer.
Very frustrating since I wasn't force roaming, have 6 lines and can't afford other carrier and I actually like sprint.
Sent from home How do I turn my phone on?

My phone came with El29, and after seeing loss of signal often I started experimenting with modems. Tried fd19, fd24, fd26, and fe07, and I still get bouts of loss signal. It's not an issue of bad reception, because my OG epic has no signal problems.

Hows the signal on FE10?

[Q] No Phone service- mms/sms/call - Stock settings

First, I apologize if there's a thread with an answer... I was unable to find one.
I’ve got a big problem with my phone…sorry for the long post, but I want to get as much info in as possible.
I have been trying to regain access to the cellular network since about 8am today (eastern time). I noticed my lack of signal when I got to work. Yes I’m in a basement, but I haven’t had problems before. I will see everything from blue bars with the 3G logo to a triangle with an x. In any case, I am unable to send or receive phone calls, text, or mms. I have a Samsung Galaxy Nexus on Verizon.
At first I thought I needed a reboot. Then a battery pull. After no luck, I thought that maybe I needed a fresh start. I have had 4 or 5 ICS-based ROMs and quite a few custom kernels, and most recently I’ve been playing with Jelly Bean. I thought that perhaps I had some leftover junk scattered about and figured that I would just format my SD card and start from scratch.
The long and short of the next part is that basically I put my phone back to stock settings, tried JellyBelly and CM9 RC1 after the 4.0.4 OTA update, but still no service! So now I’m back to stock again. The bootloader is unlocked, however I cannot root my phone. And I still cannot text or call. I have signal bars lit up, as well as 3G and am actually using Google Talk on 3G.
Mobile network is on, and set to LTE/CDMA. Aside from this morning, I haven’t flashed anything since Thursday (6/28/12). I cannot boot into recovery with ClockworkMod or Optimus Prime Touch- that just yields a picture of Andy with his chest open and a red triangle I’ve tried just flashing the radio, too. But that doesn’t seem to get me any results. I read about people having problems with their SIM cards so I pulled and reseated mine. That didn’t help, either….
I’m getting flustered and don’t have any other ideas. Could someone help me breathe the rest of the life back into my phone? I have no idea which directly to go now.
Thanks!
-Sarah
EDIT: Can't use 3G for Gvoice/talk now. boo

Probably your network. I'm having the same issues, but that's because the towers are down due the the crazy storm we had on Friday.

Anyone else on Verizon in your area having the same issues?

I hope so... I was able to call and text once I got out of the basement though. This morning, as soon as I step in, I'm getting the same thing.

One of my friends did yesterday, but only for a short time. He also has a Gnex. However, he was able to fix it by flashing a new JellyBean ROM. Only one of my coworkers is on Verizon, but he didn't have any issues here. He's got an iPhone.

Only one of my coworkers is on Verizon...he has been experiencing issues trying to text, but can still make calls.
I have finally restored my phone back to the JellyBean ROM, but still have no service
Just thought I'd update the thread.

Best ROM for voice signal issues

My story begins when i got my new shiny D710 over a year ago. I loved the stock ROM that it came with (i wish i knew what version it was). Battery life was great! Signal was good inside my basement apt. i mean, i had 2 to 3+ voice bars and call quality was good in NYC.
updates kept coming through and then came the dreaded ICS update nightmare. every call was a dropped call or just no signal at all (stop sign). i gave the updates another month or two to see if anything got better, and it did not. i made a bold decision to wipe my entire phone completely and go back to GB EL29 stock, which came rooted. I was lucky enough to move into another decent apt. on an upper floor but STILL had really bad voice signal strength on EL29, 1 bar or no signal at all. it takes about 10 minutes for roaming to kick in, then it disappears after my call is completed. is it my phone or my ROM? Can anyone suggest a ROM that enhances the voice signal? it doesnt have to be GB, but i do enjoy it's battery life without having to install/tweak crazy battery saver apps. 4G data gets a full strength signal so i dont know what i am doing wrong.
My emergency flip phone from virgin mobile prepaid has full bars compared to this thing! both are CMDA!

I myself live in NYC and for me I was using Stock Rooted FL16. That gave me pretty decent battery life as well as pretty good signal. But battery life is different for everybody and every device. Hope that helps.. :thumbup:

Try different modems. There is a sticky in the development section.

funny how i am getting full bars inside my apt. while voice roaming. is sprint limiting my call capabilities on purpose? roaming on another carrier is a no brainer. it doesnt seem like the phone is the issue. i might just give FL16 a shot. is there no way to keep voice roaming ON all the time?

There's an app called "Roam Control" by MrGreg for rooted phones where you can force roam. "Not roam control" is in Google Play Store, you can get Roam Control at the developer's website

Try changing your prl. If concerned about battery life try a diff GB modem.

I absolutely agree with this. It sounds like your problem started when you received an OTA update that changed your modem.
If you flashed a rom zip file, it did not change the modem. The modem must be flashed separately. Try flashing a GB modem.
If you want to use a GB rom, I suggest Caukulin's v3.0. Everything works perfect and the battery life is the best I have ever had on this phone.
I was never able to get a good signal at home. I can go about 1/4 mile in any direction and get a good signal. I got tired of dropping nearly every call so I solved the problem by using a custom prl that uses Verizon's towers. Haven't had a dropped call since.

Thank you so much! I didnt realize that the modem would have not changed! You are awesome!!! If I use a custom prl, would that mean that my data is also roaming or just the voice?
