Help with E4GT radios needed

I had the Evo 4g for about 1.5 years and it was a great phone. It started having problems so I decided to upgrade to the Samsung S2 on Sprint. Ever since I got it I have low signal most everywhere, can't connect to 4g unless I'm out under open sky, and my phone flips to roaming a lot. I have updated everything but still no fix. I'm rooted but on stock ATM. Please I need some suggestions for fixing this with tweaks or a better rom. Specs below.
SPH-D710
2.3.6
EL29

All I can suggest is try all the modems,at most I get 4 bars,4g cuts out alot for me

Ignore the low signal stuff. Our phone is just really accurate. Nothing wrong with our radios. You'll still be fine if its low signal usually

A lot of times when I am roaming or have really low bars I can't make or receive calls at all. I seem to remember having similar problems with a Samsung device on T-Mobile. Is the hardware side of Samsung's weaker than HTC? If it was just low signal but I could still use the device as a phone I wouldn't care, but it is just an expensive toy a decent portion of my day as it is right now.

Try clearing your nvram and reactivating.

Yeah I ignore my signal bar as well.. Even when it's low, my calls data sms are just fine.. But then again I'm in a area where sprint works great

Part of my point in all this is that I am in an area that has good Sprint coverage, the only difference between my usage is the phone. I was consistently on 4G with my Evo now I very rarely can connect or stay connected, I always had cell service on my Evo, now lots of dropped calls and static and unable to send/recieve texts unless under open sky.

Your best bet might be to try a bunch of different modems. [modems here = radios on other devices like HTC]
You'll have to root and add CWM to flash them. Modems are build 'independant'. Meaing you could be on EL29 and use an FG20 modem if you'd like. By far the best reception (both 3g an 4g) has been on the FG20.
If you want to keep your phone on EL29 stock use sfhub's 'Autoroot' and add EL29+CWM-Rogue. http://forum.xda-developers.com/showthread.php?t=1342728
Hit up the 'Modem repository by rwilco12 http://forum.xda-developers.com/showthread.php?t=1662295
After each modem flash I suggest updating the PRL and Profile too.
Find one that gives you the best signal for your area.
There are also '3g/4g speed tweak' posts in this forum That will work on GB and ICS builds.
Good luck.

You would think they would've mellowed this out of the all the phones by now, but you may be experiencing the infamous Loss of Service (LOS) issue this phone wrought when it was first released.

You can either use odin or a dialer code + your MSL.

There are new PRL out and I get a better signal now and better 3g speeds. Update prl and profile first. Next try different modems, I like FE22

Thank you everyone. I just updated the PRL and Profile again. I'll see if that makes any difference and if not I will start running through the modems. If I find something that works I'll post back.

Verizon LTE just quit. Can anyone help diagnose?

Hey everyone...Yesterday, on my stock, 4.0.4 GNex, I noticed I was getting terrible 3G speeds, and no 4G data whatsoever (even though the 4G signal existed). I thought maybe there was a temporary outage, but no dice...VZW support said there were no issues. Today, the issues still remain, and I have no idea what the problem could be. I took some screen shots, so if anyone could offer some advice, I'd really appreciate it. I'd love to try and resolve this myself instead of bringing it to some of the inept VZW techs at the local store. I'm located in Western NY and there is normally a great 4G signal here.
I can post screenshots once I am allowed since I'm a newbie here.
THANKS!
EDIT: I should add, I've experienced the 4G dropping to 3G for a while, and I know this is an ongoing issue with GNex users, but this is completely different.

Another case, same awnser, considering what you said, the device is running the latest official release, and it seems 4g never works at all: return it and get a new one, probably has a bad radio.
If we can get a NYC vzw user as yourself who doesnt have the issues you're describing, i think that would kill it as faulty hardware.

Meaning the radio just went bad? I've had this since launch day and never experienced a problem until yesterday. Also, I'm far from NYC, so if anyone in Western NY (Rochester/Buffalo area) has the same issue, let me know please.

Well, you said you have a stock phone and it doesn't sound like yourself have made any changes to cause this. So, what is it that you want to do? Flash the radio firmware? Root the phone and try different ROMs? Go through all this so in the end you take it to the store anyway? If your description of the problem is accurate, then it does sound like you have a hardware issue. Just take it in and deal with the inept VZW techs.

No I didn't want to do any of the things you listed. I was asking if anyone here could help me diagnose the problem, in other words, see if there's any way to prove it's a hardware issue. I wasn't sure if there were any applications I could get to run diagnostics checks.

If you never experienced these issues before, yes.
I would eliminate a few things (simcard, check another 4g capable phone, side by side, see if it works fine) first and do some testing.

It ended up being the SIM card. They replaced it, and instantly the 4G worked again.

Radios Verizon Galaxy Nexus

I updated to jellybean on my VZW nexus and have been dropping my signal a bunch randomly. I just got a refurbished phone from verizon and I flashed it first thing so I don't know if it is a problem with the phone or the stock AOKP radios I have installed. I was wondering if anyone knew if I can use the radios from 4.0.4 on jellybean or not?

I don't know the answer to your question, however...
Got my wife a free Galaxy Nexus from Best Buy last week (verizon)... and instantly had problems w/ the 4g. After a ridiculous period of time at Best Buy to get the phone activated (they tried multiple SIM cars) and her contacts downloaded, we finally left being assured that the 4g problems were due to the activation process, and were told to give it a day or two. I was skeptical.
So we flipped off the LTE/CDMA mode, and went just to CDMA and used 3g for a few days. Called Verizon, they refreshed the network / cleared out the lines (whatever that means), and still no 4g. Every time we'd turn on 4g mode, it would connect, then drop moments later. When it dropped, it also dropped the phone line. After a week, my wife had finally worn me down. I conceded to her that a very very very very remote possibility had occurred, and we had gotten 'a bad phone'. Dear lord, did I want her to go to Best Buy w/o me. But i got suckered (she's pregnant).
So after another 2 hours at Best Buy, a new phone, and a new SIM card... we walked out w/ the same problem as before. Apparently, there's something going on w/ Verizon's latest software version ... our only option is to use 3g for a bit. I called Verizon to try and get some free money towards my bill out of them, and the customer support rep told me my best option at this point was to return the phone and choose a different device. Talk about horrible support.
So now i've come here to pretty much try what i think you'er aiming for... maybe by going to CM9 or CM10, her phone will be able to keep a constant 4g connection... only time will tell.

There is no such thing as "stock AOKP radios." The baseband version is independent of the ROM, so whatever baseband you had after flashing was the exact same one you had prior. The signal drops are a common issue and could be attributable to the fact that there are no JB basebands released for the i515 as of yet.

The issue is with your device and not the radio's or the OS version you are on. Nothing you do will fix it or make the issue disappear. There are good GNEX's out there that do not have the radio problems, it took me three tries to get one.
Don't believe anything else you hear about fixing what you have. It is all BS.

Occam's Razor is applicable here. When the problem is persistent on 4.1.1 and is not present after reverting to 4.0.4, it's a software issue. That's not discounting the ones put there with hardware issues, but the fact of the matter is that signal problems are to be expected for vzw users running JB. We have updated binaries, but until a new baseband drops for the i515, it's not going to play especially well with JB. Such is the price for us early adopters.

I've seen two types of issues on the gnex.
1) 4g drops out and either drops to 3g or 1x for a period of time, in which it reconnects to 3g/4g shortly after. This seems to be a once in a while type issue. This seems to be more radio related.
2) 4g drops and your phone drops signal, period, for that time and then reconnects quickly. Easiest way to tell if its doing that is to check the battery stats graph and look for red slivers in your data connection. This issue from what I've seen is more hardware and I'd suggest replacing the device within your 14 days.

The ongoing theme is it's a great phone other than noisy calls, occasional drops, data signal/connection issues, and fragile glass.
And we're partly to blame. Short life cycles and youthful koolaid drinking consumers enable phone manufacturers to continue to build with a style over function mentality.

My 3rd replacement says otherwise. I have been on JB for 3 weeks now with this device and have not had any issues with 4G.
If every LTE GNEX had the same issue on JB I would agree with you but that is not the case. I wouldn't believe it either until I finally received a perfectly working GNEX. Always thought it was the software but I was proven wrong.

Go here and get the FC04/FC05 radios.
Radios are independent of the ROM, so you can install any radio you want on any ROM. FC04/FC05 are the latest basebands.

His device should already have these radios if he recently received it.
My suggestion is do not play games with radio swapping, keep excahging until you get one that works.
Also, why not restore to ICS first and see that it is your phone and not the software.

My old phone with the blown speaker on the same 4.1.1 rom does not have this issue. I never tried stock ICS, I flashed this phone as soon as I got it. I think it is the phone.

I have the drop issue sometimes but in my case I'm sure its not the phones fault as it doesn't happen at home (only at work)

Verizon 4.0.4/4.0.5 Radio intermittent signal loss

I am on my sixth nexus. I am running Vicious's 4.1.1 rom rooted and not running any weird power saving apps and turning off my wifi when not at home. The radio signal either turns off completely for a few seconds or cannot connect to data services constantly when trying to use the phone. There is nothing I am doing that creates this problem consistently. It is random. Sometimes i can make a call and talk for an hour and have no problems sometimes i can be in the same area and make a call and it continually drops the call after a few seconds to a few minutes. 4g rarely works though it shows its connected. I am running what i believe to be the latest radio for verizon I515.10V.FC04/I515.FC05. I am open to suggestions on radio's app's anything to get this corrected. I even tried going back to stock and letting Verizon update the phones to start and the problem still persists. i travel a lot and it does not seem to do it in any area more than another. but It has become a constant nu sense when talking to my customers on the phone. or trying to connect to data services. PLEASE HELP

4.2.2 OTA signal question

Hey folks,
Just a quick question I was hoping to get some clarification on:
Like many, I got the 4.2.2 OTA on Tuesday evening and everything went fine with the download and install. That being said, I'm having some signal issues that are a bit strange. For the most part the signal quality is fine. Not really having any connection issues, but I've noticed lower bars being shown overall. After doing some digging though I've determined that apparently 4.2.2 reports signal quality differently than 4.1.1 did... representing a much truer value based on dBm and not overly inflating things for constant 3-4 bars. Essentially it's like I remember way back with 4.0.2. I still find it a little odd that I can show -85dBm and only have 1 bar, but if that's how things are reported in 4.2.2 then so be it.
The thing that's bothering me though is this: at times my signal will read 0dBm 99asu. I'll have zero bars showing, but it will still show 4g in the notification bar and will say connected to the network in status. I can make calls, text, surf the web, download apps, even run speed tests without any problem (although not great numbers, they're not horrific either) Eventually bars and dBm "come back", but the amount of time for that to happen varies. Again, nothing seems to be affected by this, but it's just a little disconcerting to have happen.
So, has anyone else experienced this? Google searches show some talk of it but otherwise haven't turned up much. I've done a battery/SIM pull and that didn't change things. Is it possible something may have gone a bit sideways in the ota download? Was thinking a factory reset may help too but not looking forward to wiping my device only to find out this is pretty normal.
Any help would be greatly appreciated. Thanks in advance.

It's possible that the OTA updated the baseband, please look into that as I'm not entirely sure. If that's the case, then it might just be that the new baseband is not suitable for your coverage area in which case I'd suggest you flash a previous release.

Thanks for the reply. I'll fully admit I'm not as up to snuff on this as others, so please correct me if I'm wrong... but the 4.2.2 OTA did in fact contain new radios from VZW, so shouldn't the baseband have been updated for everyone who took it?
Mine is: I515.10 V.FK01/I515.FK02
As I understand it that breaks down to phone model (I515), HW rev 10, with the new radios being FK01/FK02
Wouldn't every VZW GNex that was on the 4.2.2 OTA have the same baseband; outside of having either HW rev 9 or 10?
Currently I'm locked, stock, not rooted... yeah, probably one of the last Thinking I may unlock and root and try the 4.1.1 radios again. Do I need TWRP or CWM to flash those or can that be done if I keep stock recovery?
As always thanks for all input, much appreciated.

My Gnexus is the same . but despite that it actually performs better oddly enough

Do/can you update roaming (*228) with the Verizon nexus? Or is that just something I could do with my old fascinate (yes, a fascinate and then nexus... I am a glutton for VZW punishment).

You can, but as far as I know you'll then have what is considered a 3G PRL pushed to your phone, something beginning with "5"... if you just let the PRL update and push on it's own like it's supposed to you'll have a 4g PRL, and will begin with a "1" Both work the same and pick up both 3G/4G signals...not sure what the true difference is honestly. I've been on 15192 for ages now and it's been fine up to this point... Think I'd just as soon keep it. Thanks for the suggestion though.

I Read some where online. That if you take out the Sim card let it for like a minute or so. Slap it back in and there you go. It work for me

Yeah, did that... battery pull and sim card pull... left it out for 30 min then back in... no difference. Like I said, it's not that I'm having a huge problem with my data connection, it's just acting... strange... kind of all over the place. Lots of fluxuation, odd readings/bar equivalents, and the whole 0dbm 99asu thing with still being connected. However I've also now started seeing higher than normal "time without signal" percentages... Just flakey. And frustrating... no issues at all until the 4.2.2 ota.

mine is not really a problem but I had way more bars of coverage in a multitude of places (work, home, gym, etc) on the old radios. I havent looked at the dbm's but visually it's different. might be something for someone interested to look into.
btw, im in fresno, ca.

Well Google changed how the signal is read visually through the bars to provide a more accurate reading. You should look at dbm

Having the same experience here (Whidbey Island, Washington) where the 4g signal clings on until it absolutely had to fall back to 3g. New radios may be contributing, but the change in coding to report lower signals may have improved the ability to hang on to a 4g signal. Hand off seems pretty slick too, but that's likely a function of the new radios that came in the OTA.
