[Q] 3G Dropping out/ Triforce ROM - Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot

Hello, I am using Sprint S4 with Triforce rom updated to 3.1. I have used the Agat and Ktoonez kernels with same result. What happens is i will have 3g service (bars) but the 3G icon disappears and i dont have service. 30% of the time i can reboot the phone and get it back but other times i have to boot into TWRP and wipe cache and dalvik cache and it will work for a little while. I notice it happens more if i travel but also when not. I have ODIN back to scratch and put Triforce back on but same thing. I was also having random reboots but the Agat kernel seems to have fixed that.
thanks

I would also like to know the answer to this....I live in Tampa and have the Negalite ROM and I notice my 3g will just drop in my house and this never happened before with my 3Devo......

To add to this i have noticed when this issue occurs and if i go into a area with 4g that works fine. But once i leave the area and it switches back to 3g it drops again.

Try ##72786#, that will do a full network reset. It won't wipe data or anything. It will however reboot a couple of times.

Just tried that, will this prevent it in the future or only if it happens.

I had similar problem and it solved it for me for good, however my problem was a bit different. Hopefully it clears things up for you also.

That didnt work, i was on the way home this evening and checked and had full bars but could not call or send receive data/texts.

3G stops switching back after wifi?

This is a strange one. I have been using Fresh Evo 3.2.0.0 rom for almost a month and it works great. I wanted to try another rom so I tried the VirusRom... it was good but I liked Fresh better. So reflashed my Nandroid image and all was well.
But then I started seeing a lot of failed connections to the market and noticed that my 3G was not connecting. I live in Chicago so I am fully covered by 3G in this area, and even 4G in many spots. Usually when I leave a wifi area, the phone switches back to 3G almost instantly. But ever since nandroiding back to the Fresh Evo 3.2.0.0 rom, it only works after a reboot. As soon as I hit a wifi zone and then lose it, 3G doesn't switch back on.
4G and Wifi both work, but if I disable both wifi and 4g.. 3g doesn't come back without a reboot.
I've even switched off the Mobile network using the widget and the power button menu.. no luck. Only a reboot brings it back.
So then I even did the trick to get my PRI up to 1.40 and that worked fine. But no change in the behavior of 3G. When I reboot and 3G is working, it works great as usual. Just not sure why the switching no longer works. I even tried switching back to the rooted sprint stock rom.. same deal.
Anyone else having any issues?

yes, I have noticed this at times. Just happened to me. Failed connection when switching off 4g to 3g. Using fresh 3.2. But I noticed this as well on other roms. I had to reboot each time to get 3g working again. I also reset my data connection last night but it obviously didnt work.
I've been having issues with my 3G for the past two days. Similar story, I did and Nand restore and that is when it started.
I am getting an error code 67 everytime I switch from Wifi, 4G or even when I reboot to try and fix this. Usually if I let it sit it will come back, but the error message popping up is quite annoying.
Wish I had something more helpful to say, but I can just add that I'm having the same problems switching from wifi to 3g. Even after 3g turns on it will sometimes turn off again randomly and I will have no connection. I'm also running fresh. In addition my 3g signals are quite week. kinda a mess...
Weird. My phone did this today for the first time. The thing is, I've been on Fresh 3.2 for a month now, and I flashed the latest Baked Snack rom yesterday to test it out. It never did it while I was on Fresh, but today after turning off WiFi, it wouldn't connect to 3G for anything. No text or data transfer at all. After I rebooted it, it started working again, but my phone never did this while I was on Fresh.
I am having the same problem and I am using Fresh 3.2 as well. I did go to a different rom but then went back to Fresh's rom and that is when it starting happening to me. It will only pick up 3g now and then and even when it does my speed is super slow. Hoping someone comes up with a fix as I made my own post but no one seems to feel the need to reply to it.
Theories...
Same here. I'm on Baked Snack 1.7x
I know Fresh and Hero both use some of the same components. I flashed to Cyano and have had no problems with the 3G radio. It's very snappy switching on and off after wifi connects and disconnects.
I do know there have been one or two issues with the radio with people who are on the 3.28.651.x roms. (for instance, if you enable 4G then disable, sometimes it randomly turns off and on without you knowing until you restart)
So my guess is maybe the 3.28.651.x series is glitchy. You guys want to try going back to 3.26.651.6 and do some testing?
happened to me on stock. Had to reboot the phone to fix it.
This seems to be working for me today with no problems so far. I am wondering if a tower was down with Sprint putting up the 4g around my city. Will keep posted if it happens again but seems to be running like normal now.
This has to be network issues maybe the latest PRL.
Mine has did the same last couple days also on power on , it takes longer for 3G icon to kick in.
Signal flux has been occurring more then norm fast download - Upload speeds taking hit some parts of the day.

I am on 3.26.651.6 build and this was happening. I am no longer having any problems with this. I do feel this might have been a problem Sprint's servers were having. Seems like everyone started having the problem right around the same time.
It must be... Going to an older PRL didn't help, and there are a bunch of forum topics being created about this on other forums as well. Guess it's time to play the waiting game.
My issue is so bad right now even if I restart my phone, it doesn't even get data connection right away. 10 minutes waiting now and error code 67's keep popping up.
This just happened to me today. It took me awhile to connect the error statement to the fact the 3g didn't turn on after I turned off wifi. But I was able to press the 'data connection' button on the switchpro widget to turn 3g back on.

That is how I got it working a little bit last evening but as I said in my last statement it is finally working and has been all day. Not sure what the deal actually was as I did not change anything since 2 evenings ago. I am thinking that Sprint is doing something which is messing everyone up at one point or another.

Nexus S total network loss.

So my girlfriend's Nexus S has been losing the entire voice and data network and going into no service mode, no biggie at first, just cycle airplane mode, then it went on to rebooting because you would select airplane mode from the power off menu but it would not check the box in the wireless settings menu.
After the reboot the box would show checked and airplane mode could be disabled and the service would resume. The the phone started getting stuck in airplane mode and not even rebooting it would bring it out the first few times, then it got to the point of resetting the phone, a wipe cache/data reset didn't fixed it. So off to T-Mobile for a new sim card. Rebooted the network immediately. And as of last night its back in full force and now not even a new sim will resurrect the network.
Have tried wiping, reflashing stock 2.3.3, new sim again, multiple resets, had to get an toggle widget to get it out of airplane mode and still a dead network, all this time the network in the *#*#4636#*#* menu showing unknown and is not able to be changed and reverts back to unknown immediately, OEM specifics settings button is greyed out and you are not able to disable the radio either.
While I'm going to call Samsung on Monday and I guess send the phone off, I worry about mine because it too does it but only once a month or so, but I do constantly have issues resurrecting the phone from airplane mode at times because the box will not be checked in the wireless settings menu but I can see the airplane instead of network bars, problem persists with reboots sometimes.
I also would like to add that even when the box is not checked in the wireless settings menu for airplane mode, if you click it it just hangs forever and will try to select but never will and stays grey like its turning everything off, but if the scren goes off its like you never tried.
Has anyone else seen this? I have seen a lot of people with data network issues or having to reboot to get voice network back but nothing as bad as I'm experiencing.
Both our phones are and have been completely stock and unmodified.
Thankfully we still have her Vibrant and in case I need to send mine in my Nexus One.

Have you tried restoring from another persons' pre-made nandroid backup?
This over-writes the radio firmware, you should give it a go!
I also found that I had problems on 2.3.3, however reverting to 2.3.2 gave me no problems!
Just contact me if you need any help restoring from a nandroid backup or finding the 2.3.2 backup files

Is that true? I am just on the verge of calling samsung. My phone won't connect to or display any available networks, and is pretty much now dumbed down to a small tablet. I've tried everything except another persons nandroid backup. I've been told to stay away from flashing another persons... but I'm really desperate.
If you could provide me with a backup, that would be awesome.
I'm having identical problem.
It was working fine yesterday, look back to it and now it's got no mobile network, nothing. Just the no bars and cross symbol. I've tried wiping dalvik cache, reflashing the radio, wiping data/factory reset, reflashing the rom, restoring with a backup (Backup of when I first rooted the phone) and still no signal. Nothing has worked..
Anyone got ideas on how to fix this issue?

Can you search for and view available networks?
This sounds like the CM7 powerwidget problem (3g/2g) I used it and I loss all network, phone process will crash every second, however if your phones are stock I can't think in anything causing it.
For CM7 you'll have to reflash and delete userdata or edit the sql database for the providers and change a value to 0, but you need root.
When I went to *#*4636.... my preferred service was "unknown" too, but now it is OK.
Try to dail:
*#*#4636#*#*
and find your network information.

Nope. Sits their 'searching' but nothing shows up.
In, *#*#4636#*#*, it gives little to no information. Just says nothing for current network and for GSM disconnects it has,
Sate: DvInactiveState
disconnected with last try
at 9:59AM
fail because No Error
And that time never changes, stays at 9:59AM.
As my above post suggested, I've tried doing a factory reset and reflashing. I don't think I use CM.. I flashed with Oxygen 2.1.6 (using it's kernel) but I restored to Oxygen rom and trinity kernel after it didn't work.

That is the EXACT same problem I have. I too was using Oxygen 2.1.6 and lost all connectivity. I've just locked my bootloader and flashed back to stock ready to send for repairs. That rom must be doing something >.>
Oh no
I didn't want to send it back D:
Anyone got some suggestions that I haven't tried?

I've been trying *everything* for last past few days. Nothing is working. That shouldn't stop you from trying though. Just stay well away from ODIN and those i9023 files, I've seen bad things.

Ok, it'd be great if you worked something out. I'm so glad i'm not the only person with this issue!
Anyone had any breakthroughs? *hopeful*
I wouldn't call it a breakthrough but I got somewhere!
Ended up putting a extremely thin piece of wire into the external antenna port at the back of the phone. Wasn't too keen on doing this, but my phone now has reception isn't stuck at the dreaded -113dbm.
The reception isn't good, but it's enough to send texts and have calls.
Although the area needs quite good reception for me to receive anything, and it's extremely sensitive. To get 3 bars in a place where I usually get full bars, I have to be outside. While inside it's reduced to none or 1 bar, which is enough to send/receive texts and a sort of lagging phone call (did a few tests). As mentioned before extremely sensitive. The phone seems to like it better when it's up-right. In the middle of the CBD at Brisbane I get full reception and 3G, which is fine but in the places where you usually get 2 bars, you get no signal at all, unless you're outside.
So this is hardly a fix. I will most likely be sending it to Samsung to get it actually fixed. Either that or get it fixed the same day and pay probably close to $100 so I don't have to wait 2 months waiting for Samsung to twiddle their thumbs.
Thats awesome! But I'm going to post mine off to Samsung USA tomorrow, which will take forever considering international shipping. Where could you get it fixed same-day? I'm going to try this wire thing
So it can't be a software issue, but maybe the rom overloaded the antenna and fried it or something? I'm glad we've got that far.
I've seen that nexus s has a problem like the iphone, the antenna gate. Try take the phone with the left hand looking to no touch the rear of the softkeys

Its more serious than that my friend! Thanks anyway
I got a quote from a place in Brissy called "FixMyMobile" and they said if they can fix it, it will cost $99. Although I'll get quotes from different places (if I find them) and see what they charge however I don't think I will be able to get cheaper, most likely around the same price..
So I may do that to not wait the ridiculous time it will take to get it back from Samsung.. Not sure on places in NZ though.
Yeah it seems like a hardware issue definitely. I eventually reverted the phone back to stock everything and it still happened, so that there shouts hardware issue.

Rooted OTA 2.3.3 Loosing Data

So I recently updated to the OTA rooted 2.3.3 by clearing all data, sbfing back to 2.2 and then updating to 2.3.3 OTA rooted. I have noticed recently that every other morning or so my data connection is just gone. I can turn airplane mode on and off and it does not come back, wifi works fine. However if i disconnect from wifi I get no data and I can't make a call or send receive text messages until after I reboot, just wondering if anyone else has been experiencing this and if there is a solution or if I should just clear the data on the phone and see if the issue goes away.
That is not good. You may want to SBF again to see if that works
I have the same problem on my non-rooted droid x. data connection goes away and doesn't ever come back until you reboot. I've seen other people have this problem in a few other forums also...
Well I did a factory reset and install only launcher pro and google voice. Will use like that for a few days and see if it happens again.

I sorta had this issue last week -- mine was dropping from 3g to 1x in my daytime location --i am here everyday so I'm familiar with the speeds/signal strength for this area.
Also I had never had this issue... ever. I was on the .595 GB leak, but I sbf back to .340 (didnt root) and STILL had the issue. I did data and cache wipes in recovery while on .595 plus a factory reset even after the froyo SBF.
So nothing worked..... GB, Froyo, rooted, non-rooted, factory resets, data roaming disable ... it still would drop 3g for 1x. This was just out of the blue, I've had the phone since Dec. 2010
I thought it might be a tower issue, so I suffered with this nonsense for 3 days, knowing that VZW would likely fix tower issues in that time.
After additional research, I found those saying a battery pull would do the trick. Well heck, after all that angst and effort a simple battery pull did it !
Not one problem since. Try the Battery pull !

I'm having this occasionally as well.
Curious as to why a battery pull would do anything different than a reboot?
FWIW I'm on .596 rooted

It isnt any different. I've had this happen a few times and it keeps coming back in normally bad signal areas, but not every time. I have also had random reboot when the phone is in my pocket, unlike froyo where the reboorts happened when I was doing something important. I suppose that is progress then.

Galaxy Note losing data?

I've had my Galaxy Note for a few months now with no issues, all of a sudden last week it would show the H logo (but the little arrows showing data conntection would not move). but when I clicked on anything I would not have any sort of internet connection. I have to restart the phone to get internet connection again, I was on a new rom for over a week before it started happening, I tried 2 other roms since then and still have the same issue. I am about to try a stock rom and see if it still happens. I have also tried different kernels, is there anything else I should try? I show full bars for phone signal and still receive texts (not mms) normally when this happens but no data at all until I restart my phone.
Do you have any "power saving" apps like juicedefender? If you do, you may want to check your settigns as it could be disabled by said app (although you should be able to reconnect at any given time).
You said you have switched roms to see if the issue persisted. When you did this, did you full wipe or just wiped cache?

I've been having similar problems with a few of the custom roms (but can't remember if stock does it or not). In my case I'd lose data for about 5-10, then it would come back, and it randomly happened. I fortunately don't have to restart the phone to fix the issue like you do though. :\ Let me know if the stock rom fixes things!

I don't have juice defender or anything like that... even when i restart my phone, it takes forever for it to catch data, right now i restarted it, its been probably on for a good 3-4 min and still not showing any data.
I always full wipe when I install a new rom.
and it finally came on after a reset but usually data shows the second the phone turns on, this time it took it a good 5 minutes before the H appeared
I would suggest restoring to your first backup after you rooted your phone and see how it goes with the stock rom. Good luck!

[Q] Galaxy Note Data Connection Lost

Hi, I'm currently experimenting with TMT Rom 1.2 (been using Midnote since i first got my Note a month and a half ago, trying several versions)
I noticed something with all ICS roms I tried, data connection works fine until I'm in a low coverage area (mostly at work or home, big building where i can hardly get a signal) when I leave for/from work, as soon as I'm on the street, I don't get any Data Connection, with some modems i would even get a "not registered on network" when attempting a call, even with full signal bars
The only fix that gives me data connection back is to restart the phone, that works every time, sometimes by playing with the 3g/2g/auto settings, which also behave erratically (sometimes i cant switch from one to the other) i can get it to work, but most of the times I need to reboot.
Has anyone encountered this issue with ICS or even GB roms?
I have exactly the same issue, now running CM9.
I just can get back the connection by rebooting the note

It happens with me as well. Since using 3G data shoots up l2_hsic wakelocks, I usually switch it off while not using. Unfortunately, that toggle doesn't work after twice or thrice and I need to reboot to get my data connection back. Surprisingly, it never happened with me on GB before. I was and am using stock Samsung ROMs without root.

For me the issue seems gone for a couple of months now. No issues with Criskelo's ROMS or the latests versions of TMT Rom
