[Q] Only 4G Network Working - Samsung Galaxy S (4G Model)

Well I have this SGS4G and I updated it to kd6 and it messed up the network. I almost never got a signal (it would show the circle with a line through it). I flashed it back to KD1 rooted and now it works but it only gets 4G network. Whenever I get out of range of a 4g tower and the phone switches to GSM it gets no network. Is their anyway to fix the radio firmware on this?

Please use the Q&A Forum for questions Thanks

Go to the market and download an app called GPS Aids. Go through the initial set up with it, then under the Tools menu at the top (not the actual menu name, but it's similar), then scroll down the screen until you see an option called Hard Reset. Give that a shot. Bear in mind that you will lose any data you have on the phone when you do it.

Kd6? Never heard of it... Have you tried flashing a different modem?

KD6 would be the gingerbread update. Phone was fixed with a new sims card even though we got a new sims card when it was bought, turns out it was one of the older defective ones

[Q] Unable to get 4g

Alright, I'm a flash addict, love trying all the roms and well I was switching from bamf 2.0 beta 4, to Gingeritis VIII. I did my wipes and everything special, yet when I finally load it up, my 4g is not there. I'm in a 4g area, and I can get 3g but not my normal 4g. Not sure what to do, I even tried restoring back to my bamf rom with no luck. I had it before I did the switch and it was working fine. Anyone else having a issue or know what could be causing my problems? Forgot to mention I did try changing the radio settings and doing a fix permissions, neither did anything.
Did you update the radio?
Have you called Verizon to see if there is an outage? My 4g went down for a few hours yesterday, might just be them working on the network.
Radio was updated and I'll give big red a call, I mean its kinda odd I hold my 3g easily yet my 4g dies. I've had my 4g all night, and it did happen in the morning, so maybe they are working on it.
Called big red and they told me it would be back online soon just a short outage in the area. Came back online as I was typing this lmfao

Everyone needs to remember, VZW is constantly upgrading/testing/fixing their LTE network. Things like this will be going on most likely all year as they continue to roll out to more cities/markets. First thing to do if your 4G starts acting up is just give them a call. More likely than not, they are doing work, it's just coincidence that it stopped working right after a flash
Yeah I can't get 4g to work either. It might be because I don't have it yet. I figured I would just flash rom after rom till I find one that works.
Just trying to get past 10 posts.
I am also in a 4G area (Los angeles) and had 4G all the time but when I upgraded to the Gingerbread leak I lost it and yes I flashed new radio, its been about a week now. Haven't called big red yet and also haven't heard of updates in my area but 1 week, that's a long time. I also reverted to froyo with accompanying radio and no change...wondering if anyone else in LA area has the same problem or do I have a problem with my phones hardware...
Be sure to reboot the phone like 5 times. That brought it back for me.

I haven't had any data since friday afternoon. I had it connect to 3G earlier this morning but it promptly disconnected.
I've tried rebooting since friday. Setting to CDMA, enabling Rev A from ##778. Still nothing.

I called tech support and let them know of the issue, said there is no 4g outages in my area (los angeles) and was instructed to factory reset, which i do before any rom install then i gotta call back-if and when i get this resolved i will post the outcome.
Not sure what rom you're on now, but whenever I flash something if I lose data I have to go into the antenna settings and force 4G for a while and it will pop back up

I'm still on Baseband 1.16.00.0223 and Software 1.12.605.6
Could it be since i'm rooted and have not applied the OTA, that verizon is refusing to authenticate my data (connection)? Because when i look at lteonoff, it says i'm connected to whatever network i specify, (LTE, CDMA - eHRPD OR Rev. A [if i go into ##778])
If I go to options ->software update -> check new, the 3G or 4G icon will pop up and checks for a newer firmware. It tells me there is a new update and i can press okay, defer, or deny. As soon as i exit that and try to use the browser, the 3/4G icon goes away. Should I update to the MR1 OTA?

Im just in a 3g area and everytime I go to a gigerbread rom and radio all I get is 1x. Then reverting started jot even fixing the problem. After about 10 flashes back and forth and rebooting a hung I finally ended up on Froyo with 3g. I'm staying here. Not worth my time to run gingerbread.
I was running a GB rom and this afternoon lost all data.
If I take out the sim card and reboot, I can get data for a minute or two...then it goes again.
I'm going back to stock and taking my phone in tomorrow.
Ugh to the guy that said call tech support to see if there is an outage, I don't work in a call center but do in a store and I hate when people come in or call for outages my suggestion is to follow @vzwsupport on Twitter they will let you know in no time and it keeps you from having to go through the menus and crap.

No 4G since the update

I applied the update late Friday night and have not been able to get a 4G signal since. I'm normally in a strong 4G area and had not had any problems like this in the past except for the nationwide outage of course.
I've tried battery pulls, toggling LTE off and on and even did a factory reset. I then talked to tech support and they did a few things on their end that were unsuccessful. They then told me to get a new SIM card but once again, no luck.
Tech support is at a loss to explain what is going on and has escalated it to the higher level of support. It can take up to a week for them to get to a ticket so I guess I'm SOL until they take a look at it.
Anybody else having 4G problems since the update?
I haven't applied the update but have been stuck in 1X all day as well. I also pulled the battery, switched back and forth on Rev A, and toggled LTE. Nothing. Was going to revert back to a saved ROM next. My wife's phone happily receives 3G.
Did the update Friday night and 4G is as strong as ever.

My 4g is also working. What is weird is when I loaded a ROM I lost all signal. I loaded another Rom and nothing. I had to load radio file in hboot and I was back in business.
yea in such circumstances I had reflashed the radio and it works just fine, give it a shot
Received a replacement today, popped in the SIM card and am back to 4G. No idea what happened but the update is definitely to blame.
Yeah I got mess up too with the new update. Had to get a new simcard today and it work ok.

glad you got it worked out. I would have reflashed just the radio to try and fix it.
Having this issue as well since yesterday (7/11). Loaded Th3ory 5.0 with the newest radio to two different Tbolts (mine and a coworkers) and we're both experiencing the same issue. Flashed different versions of the radio, including the newest one again and had 4G come back for a short period of time before all service was gone again. Not sure if its an issue with Th3ory rom itself and since I cant post in that thread until I make a few more spam posts about nothing to get my post count up, I figured I'd post it here.
in Mid-town NYC where 4g has never been an issue before.
I should add that I wasn't rooted.
What happens if you're Rooted and running a custom ROM and you do a SIM Card pull? I really want to try this method, but i'm scared this will force my phone to download the new OTA update and that i'll either brick my phone or run into some serious issues.
I have had trouble for the last two days getting 4G, never had a problem before.

You dont need to pull out the sim card, pulling the battery is good enough. All it does is update the PRL.

[Q] Sidekick 4G Connectivity Issues

I purchased the Sidekick 4G from a Pawn Shop recently and immediately started tinkering; rooted, changed roms, so on.
In the haste of all of this it never dawned on me to put my sim card in, long story short when I turn the phone on with the SIM in it takes unusually long to connect and when it does it rings twice when a call is made and disconnects. When connected through WIFI calling though it works flawlessly.
While using the Smooth Maximus ROM GingerClone it would not connect at all so I commenced to changing the Mobile Network settings to GSM only and it worked through Edge perfectly.
I went back to stock (KD1 and KG2) and the results are that it will take about 2 to 3 minutes to show a connection to the network and then the full bars/4g symbol will appear but I cannot connect to the internet nor can I make a phone call.
My question is, after this long explanation sorry, is what is it that I'm doing wrong? Or is it the phone that has a malfunction I am not aware of?
Any help is highly appreciated and sorry in advance if this is in the wrong place or if this question/scenario has been posed.

You probably need to manually configure your APNs under Wireless & Networking for your carrier. Without knowing your carrier, that's the most complete advice I can offer. Googling APN and your carrier name should give you all the info you need

Try calling up tmobile you probably don't have there 4G plan, w/o it you'd only be getting edge speeds. I experienced this coming from a windows mobile fone when I switched to a G2 I wasn't getting 4G you might even need a 4G sim. It could be a number of issues. . .

I have the same problem. My Sidekick 4G works flawlessly except it cannot connect to T-Mobile network. When using wifi, everything works (wifi calls, text, receiving calls, etc). When calling via T-Mobile network, it shows dialing, then just goes out of the phone screen. I cannot get data nor text messaging either when trying to use T-Mobile network.
I have reset the user setting and even flashed back to a clean KG2 firmware. Neither has helped. Also, tried multiple SIM cards all with the same problem.
Any one with any tips?
I had that problem when I first flashed some ROM.

[Q] G2X radio broken

I have CM7 installed on my G2X and the radio turns off on its own -- it reports no signal. In order to get the radio working again, the only thing I can do is reboot my phone.
Also, to even get the radio working, I had to install "APNs Backup" from the market.
I am running android 2.3.4 on CM 7.1.0-RC1-G2x
My baseband version is:

Has anyone else had this problem? Can anyone confirm whether I have the p990 baseband instead of the p999 baseband by accident? (as reported here http://forum.xda-developers.com/showthread.php?t=1037098)
Lastly, can anyone help me flash the BIN_LGP999AT-01-V21e-310-260-JUL-15-2011+0 baseband from here:
http://forum.xda-developers.com/showthread.php?t=1037120
Specifically, I am not sure which of the two BIN files to flash, and what the correct nvflash command is (which partition does it go to?)... I can't use smartflash or any windows tools...
I have done a lot of searching and I couldn't find anything to help me out, but a few topics that are relevant are here:

What radio are you talking about?
APN is a known issue for CM7 based roms.
The baseband you have right now is a g2x baseband, though, it was the one when it came out with froyo.
Why you have to partition or repair partition on your phone if it has mo issues with partition?

CM7 or any 2.3.4/2.3.5 ROM for the G2x is known to have that issue. They are working on it currently. The APN's Backup App works for me tthough.

FatalityBoyZahy -- do you do anything special with it? It allows me to actually get reception (I can't without it) but my radio will still drop and force a restart. Do you have any special settings on it? When the radio drops the tool no longer has the list of APNs and I have to "restore" to get them back.
I was using the experimental (RC1) ROM so I just flashed the 155 nightly. So far a few of my network issues are solved. I'll update if it's completely solved tomorrow.

I could send you a copy of my APN's if you'd like. You'd just need to put them on the SD Card, and restore them through the app. Shoot me a PM.
I have the same issue. My phone randomly looses connection even in good signal areas. Only way to get back on the network is to toggle flight mode or reboot.
This is a known issue on all Android phones that has persisted throughout all Android versions. Google has worked on the problem and it has gotten better, but they haven't been able to exterminate the bug yet. This phenomena occurs when the 3G signal is weak and the phone switches back and forth from 3G and Edge frequently. Eventually the phone just shuts down the radio due to it switching too much. This is the Android OS commanding the radio to shut off. It is not a hardware issue at all. I have had this issue on every Android phone I have owned. Ironically, the only phone I haven't seen the issue with yet is my G2X running stock GB. The best way to alleviate the issue is to install "Network" from the Market and set the phone to 3G only. If your custom rom has a 3G only option just set it there. There is also an app called "3G only" that accomplishes the same thing. Since you are locking in 3G the phone won't switch frequently and the radio will stay on. You can do the same thing by setting it to 2G only, but who would want to do that.
Network: https://market.android.com/details?id=de.mangelow.network&feature=search_result
3G Only: https://market.android.com/details?id=com.mobnetic.only3G&feature=search_result
I think my issue is more severe than it is for you guys. Fatality - when my radio goes out, nothing but a reboot turns it back on. Not airplane mode, not toggling data on off, not changing apns. In fact, when the radio turns off any menu pertaining to the radio freezes and asks if I'd like to force quit it.
Also, I doubt that this is the long term Android bug. I've owned probably 10 or 15 android devices and I have seldom had to restart the phone because of this. For my g2x, I have to reboot literally 15 times a day.
I had two more leads I am trying.
One was that I have a 5 year old T-Mobile SIM in my g2x and I read somewhere that an old SIM could be a problem. No such luck, the radio has already turned off with a brand new SIM.
My second lead is my baseband. I have a March 7 baseband, but the two basebands online for g2x are March 17 and a later one. So, perhaps I do have the wrong baseband?
Thanks,
Ben

Oops I forgot to respond about jboxers suggestion to limit to 3g. It didn't work, either.
The network app didn't seem to have a 3g only mode, the 3g only app didn't limit my phone to 3g (it was still 4g) it only turned data on/off and also the radio still turned off, so I tried using the phone's 2g only mode and that immediately killed the radio.

3G and 4G on HSPA are inseperable. '3G only' will give you '4G' also.

As another poster already said on TMO 3G and 4G are the same thing. In fact, TMO doesn't have real 4G. HSDPA+ is fast but it is not true 4G. In some countries it is referred to as 3.5G and here in Thailand they are calling it 3.9G.
The network app does work. You scroll down and selected "WCDMA" only. That is 3G/4G. That will lock the radio into 3G and 4G only. The 3G only app will lock it into 3G and 4G only. There is no way to say 4G only, because it is not real 4G. If TMO had LTE that would be a different story.
Ah, that's good to know that 3g=4g on t-mobile. How come sometimes my phone says 4g and sometimes 3g?
Anyway, I wish that was the issue
Does anyone else have any ideas of what it might be?
What baseband version do you guys have on your G2x? Does anyone else have the same baseband version as I do?

HSDPA=3G, HSDPA+=TMO Pseudo 4G. HSDPA+ is an enchanced version of HSDPA with faster speeds but not true 4G. Most devices display an "H" but TMO had it programmed to "4G" to pretend they offer 4G service. Both are versions of WCDMA, which is what GSM 3G is.
I found this thread that has another kernel that supposedly fixes the APN. I haven't had my kernel drop yet, but it's only been 10 minutes Here's a link to the kernel:

For install instructions, read the instructions in the linked code.google.com issue tracker:
http://code.google.com/p/cyanogenmo...on Model Network Owner Summary Stars Priority
I used:
adb push boot.img /sdcard/ && adb shell dd if=/sdcard/boot.img of=/dev/block/mmcblk0p5 && adb reboot
and everything worked fine (don't forget to clear dalvik cache on reboot).
To run the script he linked to, download ScriptManager from the app store.
It fixed my radio! Though it did kill wifi.

[Q] Nexus S 4G - DATA DROPS

I have been having this problem with both of my Nexus S 4G ever since I got them 2 months ago.
My data drops out frequently and takes a while to get back up. If I have 4G enabled, then I have to manually reconnect it as it will not do it on it's own. This happens inside AND outside. Driving down the road or just standing in one spot.
I've tried all of the radios (basebands) and about 7 different ROMs and versions.
I've refreshed the data profile, PRL, and even tried the roaming Verizon PRL and Hybrid PRL.
Gone back to stock and tried everything from scratch. Still the same problem.
Dallas/Fort Worth Area
Network: Sprint
Baseband: D720SPRKE1
PRL Version: P:40447
I contacted Sprint and they just told me to update the profile & PRL.....
Any suggestions?
I'm not familiar with the CDMA nexus s, but are you able to change APN's? At one point I'd be able to connect to 3g (I have an I9020A), but every minute or so it would drop, so I fixed up the APN's for my carrier.
iv had a few data issues
forcing PRL and account updates has fixed it a couple of times
i'v bought used phones that iv had
to have sprint force update
im on LC1
[altho i cant tell any significant difference here]
and my prl is 61086
[a business account]
im currently on slim
make sure your mobile network
is set to roam
is not set to home only
Am I the only one with this problem? As I'm typing this I lost data but still had 3 bars. I never drop calls but only data.
Help please. This is driving me nuts.

no
i go thru periods of it acting bizarre
try disabling wifi and reboot
this USUALLY fixes mine till wifi is re-enabled
and i drop the sprint connection a few times
riding around
it then fails to re-acquire the IP address.
look in your status and see if you still have an IP
when your data fails
fwiw
I never use Wi-Fi. Ever.
Happens while using both 3G and 4G.

4G is worthless here...
i dont even bother with the switch
does it do the same thing if you disable 4G?
I almost always have to use 4G (if possible) since 3G speeds are slower than dial-up.
I've tried rebooting and leaving 4G off, and still the same. Even tried going back to Gingerbread.

If going back to GB doesnt help, maybe it is hardware related?

This is happening with BOTH of my NS4G.
Possibility that BOTH have hardware defects?
Do a profile and prl update
Hit the thanks button if i helped

In the original post, I stated that was one of the things I've done.
have you checked to see if you have an IP address
when data fails?
mine shows "unavailable" when it's wonky
and wont re-aquire till i reboot.
i'v seen this on 2 phones
off and on including on oem 2.3.7
fwiw

I have the same problems. From what I understand, its a problem with the hardware. I can confirm that's probably the case, because I've tried many different ROMs (stock, cm, etc...) and they all have the same radio issues (3g/4g and wifi)...
I have an NS4G in the DFW area and haven't seen the issues you're reporting. I'm currently on 4.0.4 with D720SPRLC1 baseband. Maybe I'm just lucky and have a good signal at work and home. It's very rare that I find an area of DFW where I don't get any data signal at all. Not sure what to suggest.
I get random drops too and i hate it. My 3g speeds are fairly good even above 1 mbps. Highest i ever got on 3g was 1.51 mbps
Mine will lose data if I'm in a coverage free area for an extended period of time, when I'm back in range 3g icon will show up just never reconnect. A reboot fixes it
Certain Areas
There are certain areas where I live that data just disappears. Although this is just a network thing I believe. It's weird though when I am driving it's like a 10 second drop and then all is good. Hope you get a solid fix!:victory:
Backup 4g Partition
REMOVED - was a bad idea.
I've actually replaced BOTH of the phones with brand new NS4Gs and they shipped with ICS.
Still the same problem.
This is driving me nuts. I was driving and trying to download Maps for the new phone from the Play Store and it took 6 tries. Kept saying RETRY.
What I've come to believe is happening is:
When 4G connects, 3G disconnects. When 4G drops (which is does frequently), 3G has to reconnect.
***Is there a way to keep 3G "on" in the background while 4G is connected?*** Maybe a way for the radio to transition back and forth?
