3g and 1x icons

Ok I don't know if any has this problem but when I'm in a stock Rom I have both 3g and 1x Icons but when I flash a custom Rom I only get the 1x icon why is that it is mind boggling pleas help

I've noticed this occasionally as well, I would think that the stock ROM isn't reporting your signal strength accurately, or something like that.
You do have mobile data on, correct?

From what I read, cannot remember where, this is an issue with cyanogen. You are on 3G when data is enabled but the status icon will remain 1G. Or I have no idea what I am talking about. My phone is reporting the same btw. When I go online I use 4G or Wifi anyway. 7.0.2.1 stock PRL 01115 Baseband 2.15.00.11.19

That does make sense, I had the same issue when I was on Cyanogen.
OP, as long as you don't notice a different in speed and connectivity, then it isn't really a problem, I'm assuming.

Then again better wait till an expert confirms it. I would like to know so I can answer it correctly later on. You could test your speeds with data on in areas you know you do/don't get 3g service and post the results.

yes data is on but if i flash a regular stock rom like the factory but rooted the 3g icon comes up at the start with no problem but if i put some of the fancy roms or any of the 2.3.3 roms i only get the 1x only i dont know why is this i flash and flash and stilll the same crap .....

well i guess no help but im on the new virus kingdom port and mann it is fricken sweet " in my peter griffin voice"

The answer
Try *#*#4636#*#*
Choose Phone Information
Set preferred network type to CDMA only
Back out, your change is saved.
You should see 3g only now, just as you would with a sense rom.

[Q] cant update profile

I live in an area with perfect 3g coverage yet im luck to get 3 solid bars of signal and download speeds never exceed 30kb/s. tried updating the PRL manually, no change. So then I tried to update profile but when I did i for an error no network connection message. I get this message regardless of whether im in wifi, 3g, or 4g. Is this a bug in the leaked ICS builds or is there something wrong with the phone?

No issue here, what build are you on?

Darkstar 1.0.2 (FB27), Same issue on FB21 as well though.

Try a different modem, I'd say kernel too but I'm assuming because we haven't gotten a repacked fb27 kernel yet your still on stock. I haven't had any issues with the FB leaks, occasionally I'd get an error message trying to update my profile and prl but i'd reboot, wait an hour then try again and it would update fine. I would try a different modem, since there isn't cwm yet for fb27 (unless your using fb21 kernel with a broken camera) you gonna have to flash a new modem through odin.

yeah im using fb21 kernel until pb27 gets repackaged. ill flash a diff model and report back.

Ya try that first man, because the FB21 rev2 break the camera, so it could be related to that too

Flashed FB15 modem. No change in data speed and still getting the "Error: Connection Error" when trying to update profile.

It's probably the kernel then man, flash the stock fb27 kernel through odin then try and post back

on it. brb

Stock fb27 kernel. same deal -_- maybe ill try reflashing but i remember having the same problem on fb21.

Strange stuff man. You've never had any errors on boot have you? Any failed flashes in Odin or accidently flashed a modem through the phone option in odin
Sent from my SPH-D710 using XDA

Nope, no boot errors. No accidental flashes. Maybe I'll odin back to EG30 and see if the problem persists.

Does your phone have a repaired esn? I never could update the profile or prl when I was running one. I always had to update the donor phone and then pull the info from it. Are you getting an error 67? What is your ping from speedtest? Usually 1X my pings will be 800-900 ms and 3G is under 300ms.
If your phone is legit, call Sprint tech support.
In my area, 3G is so bad the I hardly ever get over 100kbps and I have full bars.

Um, bought the phone legit from Best Buy. I called tech support this morning but they always got to the step where they tried to have me update profile which I cant do which is when I came here for help.
I'm in the process of Odining back to EG30. If its a problem there as well im going its going to make me think the phone is the problem and Im may look into getting a replacement. I want a white one anyway..

Just in case it wasn't obvious, update profile only works on Sprint's network. It doesn't work while roaming or over 4g.

Yeah, I'm not roaming and 4g is turned off. Thanks though.

I suggest you ODIN back to EL29 using the Full ODIN package in my signature. Then let the hands free activation (HFA) automatically run and update your phone. I suggest EL29 rather than EG30 or EK02 because your phone will try and download the EK02 and/or EL29 OTA updates wasting bandwidth and making your phone slow while it does so.
If HFA doesn't work, try update profile by hand. If that doesn't work, try ##786# reset from the dialer. Enter your MSL when it asks for code. To get your MSL, type
Code:
getprop ril.MSL
from adb shell

Ok will do. I re-flashed the fb21 kernel so I could make a backup of my current ROM real quick. Ill odin to EL29 once its done. Thanks for the suggestion.

Ok, so I'm back on EL29 and was able to updated profile and prl but download speed on 3g still only topped 40kb/s with 120 ping and 4 bars. I'm in a strong Sprint 3g area so I'm beginning to think there is something wrong with the 3g radio on this particular unit.

I doubt there is anything wrong with your radio with 120ms ping and 4bars.
It is more likely your tower is overloaded or you are connected using 1x instead of 3g. Stock Sprint software always displays 3G whether or not you are connected 3g. Although, with 120ms ping (1x would be slower ping), my thinking is you are connected 3g, just the tower is overloaded.

[Q] Custom Rom and 4G troubleshooting

Hello xda. I need some help with my GS3 and LTE. I rooted my phone on day one and have moved from rom to rom. I live in the SF Ba. Area and they are turning LTE on. Using sensorly I found some LTE areas, but my phone won't connect. I have tried different roms: CM10, Paranoidandroid, Ktoonsez, and now Liquid. I started with radio LJ9 and am now on LJ7.
I hope someone can give me a few ideas on what to try next. I heard updating the PRL can help, but I don't know how to do that.
Sorry if I did a poor job of searching, I am on my tablet, on 3G, and I couldn't find much

To update your profile and prl (prl is for roaming and doesn't effect lte).
menu -> settings (scroll to the bottom) -> system updates -> update profile / update prl
I'd odin stock JB or ICS and test LTE that way.
Though all of the ROMs you listed should have perfectly working LTE.
good luck

I flashed back to a Odex stock, and updated my profile and prl (just incase). I still don't seem to get any LTE.

Well I'm not 100 % on what fixed it but it suddenly started working. Speed seems a little slow. 5mbps up and down. Don't people get in the range of 10 to 20

On CM10 (and all AOKP ROMs based on it) eHRPD authentication is not working right yet. I think they're close to a fix, but for right now, if you're in an area with a weak LTE signal; you're gonna have some problems

Loss of 3g and 4g data (mobile network state disconnected)

I have been having some serious issues with data ever since rooting and flashing custom ROM on my Galaxy SII which is on Boost Mobile. When i first got the phone before i did anything to it, i was getting pretty good 4g and 3g speeds. After rooting i noticed that my 4g and 3g speeds had dropped significantly. I called boost they said there is some work being done in my area, which i think was crap. I was running baked ROM 4.2.1 JB and it ran nicely but i had no 4g connection by this point and had only 3g connection but VERY slow. I thought to restore my saved backup of rooted stock and maybe my speeds will come back. NOPE 4g still doesnt work at all and NOW 3g doesn't work either. I've checked APNS it seems to be correct, but my connection status is still "mobile network state disconnected" . Oh, also i've tried flashing different modems and kernel repacks cause i know using custom stuff can bork ur 4g.
Can someone help please?

Right now i am on Stock Rooted, Using modem FI27. Before i was using baked ROM as my daily driver on FL24 Modem, thats when i noticed 4g had gone completely. I am using AGATs kernel FI27 repack. Its strange though my baseband says Fi27 but build number says FL24 on the end. Should it be that way?
oh btw my 3G came back, it just took forever to connect. But my 4g still wont work, it connects to the network but it still says "mobile network state disconnected".

[Q] Epic 4g touch frustrating mobile data (3g) problem

Hey guys,
Epic 4g touch D710 running liquid smooth 3.1 android 4.4.4.
Baseband version : EL29.
The problem lays on the mobile data, I will have 3g icon that appears on the signals bars but no actual internet, No browsing no data coming or going !!..
Some were suggesting going back to stock GB28 or GB27 and then re-flashing with ICS modem which i did but no joy, I'm still stuck with mobile data icon but no actual data.
One thing was noticed that when connecting through kitkat the IP address I get from the carrier is 10.0.35.225 but when I was on stock GB27 or GB28 I get something like this 205.168.53.26 and data is just working just fine, I have been reading for so long right now, it's really frustrating to see everyone talk about having a great working mobile data by doing some steps which I have already done.
My carrier is : Yemen Mobile which is equal to sprint in the US.
Any idea how to solve it please? Please see attachments..
