WTF is up with my 3G?

My phone has always randomly had a little glitch. For some reason, once every so often my 3G icon just disappears and stuff like my internet and market dont work. SMS still works fine though. Normally just a reboot fixes the problem but today I had to pull the battery. This happened even when I was fully stock but now I'm running DC 3.2.3 still with the stock kernal. Any similar experiences?

Running all-stock with no root. Happens to me also.
Full bars for signal (calls and texts) but the 3G icon stops transferring. I just put the DATA widget on my homescreen and toggle it. Not really a big deal...so far.

Same things happening to me it wont connect to 3g and freezes most of the time. Just started about 2 days ago

Anyone know anything about this problem? My phone now randomly restarts even when im not using it from trying to connect to 3g im guessing. Keyboard also stops working randomly

are you running a rom?
...If you are you should try flashing a stock rooted and see if the problem still exists. If it does you may want to try to unroot, go back to stock and update everything. Then you can narrow down if it is rom/software/hardware related

Yes i am running stock rom rooted. What do you mean by update everything?

I was also running stock rooted at first. Here is a weird update I just came across though. I've installed (and uninstalled) SwitchPro, which is basically a more customizable widget than the stock power control widget, 3 times now. And every time I add the actual widget to my home screen my 3G instantly disappears.....wtf? I uninstall it and reboot my phone and it's back to normal.
I'm gonna dig in to this a bit after I get back from the gym.

I just meant that if you unroot the phone, make sure your radio's are updated to stock, update your profile and prl, then you could determine if it is hardware related or maybe you just have a bad signal?

I think he means Device Self Service. Updating your PRL, Firmware and Profile.
I forgot to mention that when my 3G becomes "sketchy" this is the 1st thing I do. After that do a soft-reset and pull the battery out.

##RTN# - enter MSL - click menu, reset.
This is the only way I've found to fix this.
It wipes out ALL of your information so make sure you are backed up and synced. It is just like getting the phone new out of the box - it will auto-activate and you should be good to go.
If you don't have your MSL, call Sprint technical support and ask for it.

Thats pretty disapointing that that seems to be the only awnser. Will try when iget back from my vacation. The problem that makes me really mad is that it reboots randomly even when the screen is off in my pocket. Any backup app recomendations?

Network Connection Issue - No 3g/4g

OK, I have been dealing with this since I bought my GSII and cannot find any information about it.
Firstly I want to say that I am completely stock and unrooted.
My phone does not like to keep a stable data connection. About 50% of the time, when I try to do anything that requires a data connection (facebook, browser, gmail, etc.) the 2 arrows under the 2g/3g/4g icon will stick being grey and my phone just sits there "loading". I tried a factory reset, didn't install any apps, and also got a new sim card and the issue remains. It happens everywhere so it is not just a bad network connection.
I decided to post the question here because yesterday I was playing with my brother's GSII, and his did the same thing.. So it made me think that maybe it wasn't just me. Has anyone else experienced this? Or does anyone know what might be the cause?
Edit: I set my phone to use 2g only, and the problem vanished.. So it doesn't like to connect to 3g/4g.

Try going to your mobile network connection settings, choose access point names, hit your menu button and click "restore defaults".. It may fix it, I had data issues and it did the job. Hope it works for you!

Do what the gut above me said. Also call Tmobile and tell them, they will refresh your data connection on their end. That will clear up three problems your having.
But if it's also happening to your brothers phone, it's a network error. Call Tmobile.

I restored the apn settings and had Tmobile refresh my data connection, and it still happens. I noticed today that it's not just data, I'm also unable to call or text when it happens.. Tmobile just said everything tested normal so there is nothing they can do.. And I really don't think it's the phone so I don't want to exchange for a refurbished unless I have to.
Sent from my SGH-T989 using xda premiu

Its happened to me before. For about a week, the data connection just dropped. It would come back for a bit and later vanish. I called t-mobile and they guided me through routine steps (i.e. taking the battery out, rebooting, resetting) but nothing seemed to work. They really couldn't figure it out and later told me to replace the SIM. I can't remember if they shipped me one or had to go to the store but either way that relieved the problem. This was on an HTC HD2.
That might not be the case with you though. At one point in time all the phones under my name lost data connectivity just as you explain. This really had no solution but to wait it out.

you mentioned your brother's is doing the same thing, its probably not the phone, but rather the cell tower your connected to is fuggin up. Try going 5 miles from where you currently are and see if its still happening.

Network error
Sent from my SGH-T989 using XDA App

Just in case it's not a cell tower or network problem . . . My SGS2, purchased in October, had the same symptoms as the OP. After trying everything the OP did, and more, I came to the conclusion that the firmware on the phone was corrupt. I used Odin to flash the factory stock ROM & Kernel images (2.3.5 at the time). There was a definite improvement in the faltering/hesitant/fail connectivity problem at that point, but it was still very subpar. So I then also flashed, again using Odin, the baseband ("modem") image - I did it twice for good measure. The problem was finally immediately solved at that point and I had very prompt loading of webpages, etc. Still working fine months later (and even better with a custom ROM). See the thread entitled "[Q]Is there a "true" factory restore for T-Mobile Galaxy S II?" for help about the seemingly same symptoms/problem you (and your brother) are experiencing. If your underlying problem is in fact the same as mine (and the poster of the thread I cited) then it's apparently either a bad factory flash or a post-factory corruption occurrence that is causing your problem . . . the coincidence of your brother also having the same problem aside. Good luck!

Restored imei but problems [update][fixed]

You would think I learned my lesson but im back to square one. This time however I did back up the file and did the restore. My problem is the connection is horrid very slow I tried some of the methods posted but no luck. What I'm noticing is the dBm keeps going up and down and switching from edge to HSDPA and to utms I believe it is called. Anyone with these problems?

I backed up the file as peoplearmy thread says to do as soon as i got the phone. Everything was fine and then i lost my imei, i so no biggie, located my backed up qcn file and restored. Afterwards i seen my 4g come up, i said cool i tried to use it the arrows would go about then signal would drop. Then when i back out of say Market app because nothing is happening the signal goes back up to full, like every time i try to download something the signal goes out, the dBm goes crazy too.

Yea flashed every radio available no luck, i doubt switching sim cards will work but i'm even going to try that.

I'm noticing slower speeds after rooting. How do I know if I lost IMEI? I see in About -> Status. I didn't. Back k it up before I rooted. No one mistake. Is it too late to fix?

Thing is i have no QNC back-up.......there is a QNC generator but it says the binaries are not finished for Tmobile....so that leaves me wondering....could i use your binaries and write my NV back up over that to get everything working again?

What about those of us that didnt backup a qnc or efs before root?
I've been searching all day for a way to get my 4g back after losing it following a permission fix in CWM. I love that the 20+ tutorials I read on how to root your phone never once mentions backing up these additional items. At this point, I would sacrifice all my contacts and apps just to get my data connection off EDGE and back on to 4g.

No 4G/3G

Ugh! So where do I begin.. First of all I am running the MOAR most updated version in the OP. Have been for a while. Haven't been able to update PRL/Profile in I don't how long. So I like to here and there to make sure all is well. Anyway today I started messing with it and I used some secret code I found in the MOAR thread for hands free activation. Well, that went south since I am unable to update PRL/Profile. Then I called Sprint and she got the hands free activation off. I was still unable to update PRL/Profile after that. I went ahead and downloaded the latest MOAR and wiped EVERYTHING!! Then flashed the MOAR. I am not sure exactly when the 4G/3G problems started to happen. I am thinking before I flashed the ROM again. But anyway in a nutshell I I can not still update PRL/Profile. Gives me internal error and now I have no 4G/3G. Sprint wanted me to call them on another phone and I assume to deactivate my phone and reactivate it or something idk. I remember one time my sister had this issue and I was in the phone 5 minutes and it was back. IDK why I am having such a issue.

I had the same issue on my first flasb. Forcing hands-free activation fixed it

Right. That did fix it although after I still was unable to update PRL/Profile. But right now I am having an issue with no 3G/4G. Sprint said it could be a hardware issue with my antenna which I find hard to believe. I am downloading another ROM now and see if that works any better. Not sure what else to do. I don't have 50$ and I am not trying to pay for it. I find it hard to believe that my antenna is just not working. Although I was on the phone with her for 50 minutes and it seemed like we tried everything I just don't want to give up.

Odin back to full stock... Usually clears up lots of issues. You can reroot and flash moar again.

Is odin back to stock difficult? I would think it would be easy since to root is fairly simple. I am going to keep downloading this ROM. Then go back to stock and see if that works.
EDIT: So on my second call to Sprint today this guy said I need Sprint Zone and I need to activate my phone. Having our phones rooted I did not have this app. Thankfully I seen it posted so I put it in my DB and installed it and it installed but the app was no where to be found. I even flashed the app pack and installed it same issue. Then I called Sprint two more times just to come to the conclusion that my phone antenna could be defected. Which would cost me 50$. Anyway, I thought it was something else I could do. Sitting here downloading a ROM on my phone and on my laptop going to thread to thread. Hangout convo to hangout convo I see the status of the download. Well what do you know Sprint Zone is updating. So I updated it and it opened. Said my phone was not activated. So I activated it, phone restarted and I have 4G LTE and I went to the browser and it works. Finally caught a break. Thanks guys!! @edfunkycold @CNexus

*No signal strength after multiple flashes and recoveries

*No signal strength after multiple flashes and recoveries I have flashed multiple Touchwiz and Aosp Roms as well as restored the original stock firmware. (JediX20 and JediMaster + PacMan 4.2.2 and 4.3 + Stock Firmware Samsung 4.1.1 and 4.1.2 and even updated to 4.3 and downgraded back to 4.1.2) Nothing seems to work sometimes when I boot up ill have signal and my phone will work. Sometimes ill make a call while I have 3 signal bars or more and the phone will just be in dialing mode and after 10 seconds or so my signal will cut off and the call will disconnect saying there is no signal or "out of service area" and as soon as it hangs up my service bars reappear. And then there are times where the phone will show no signal strength at all for the whole time. In all instances data will still work. I have flashed and recovered through odin multiple times but I know the issue lies within the software I just dont know where. EFS maybe? I even thought it was in factory mode and downloaded titanium backup and deleted every "Factory Test Mode" I saw. Still no luck and im bout to the point im about to chunk it. Any ideas of why it is doing this? Any help would be much appreciated. A phone aint nothing if the basic functions of call text and web doesnt work.*I have also tried flashing K7 MA4 J2 and UCAMH3 Modems. None seem to help the problem.

Possible on the EFS...but that file is really an all or nothing deal...
It is possible to have a bad antenna or radio chip....but I do agree with you on a software fix first...to include a custom APN setup with experimented entries...
I've also heard that arbitrarily bouncing between 4.1 and 4.3 roms does alter the partition structure slightly ...but after looking into the EFS on both frameworks....I've noticed they have the same size and the information is identical...
I wish that I had more help for you....g

My phone has always worked flawlessly until now. The signal can be normal but when I make a call it rings forever. .. the signal drops..my phone says it's out of service area and hangs up. .. and soon as it hangs up the signal bars reappear. .. in that specific order. It had never done that before until recently

Greg,
Do you know where I can get details about the antenna issues. I searched several forums that pointed to the usb flex. I just replaced mine and still have the same problem of weak signal and constant signal drops.

Thanks man ill try this out. Isnt there a way to just wipe the efs, system,data, dalvick, cache in TWRP and start fresh?

Do "NOT" wipe your EFS FOLDER...and do "NOT " re-partition your device in Odin either...
Simply use TWRP and wipe system ...data....dalvik...and cache...
Also ....you can wipe your internal storage as well if your important items are stored on the external SD....(photo's etc.)..
And as for the antenna question ...just Google it....g

I was poking around in my efs folder and went to Factory Apps and found a factory mode script. I opened it up in RB text editor and found that the script said on so I assume that it being on must have had something to do with the call feature. I changed the script from on to off and saved it. Soon after I tried making a bunch of calls its been working flawlessly but in exchange the lockscreen will not show up nor does the option to reboot/power off/airplaine mode shows up. Im going to Keep testing the calls in the meantime.

Im experiencing a problem nearly identical to yours. I have an i317 unlocked using a Tmobile SIM. Everything was working fine until I flashed a rom (I believe I accidentally flashed a rom with a Tmobile radio which boot looped the phone). After fixing the bootloop and flashing the cyanogen mod rom, I started experiencing the frequently dropped signal.
I have downgraded and gone back to stock several times which has not fixed the problem
After reading this thread I changed the factory mode script to off, but it doesn't seem to have affected the radio performance.
I remember reading that the partition could possibly be corrupted in a bad flash. What is the best way to reformat the partion?
Any help greatly appreciated

Did you reboot the phone afterwards?

Yea still no luck. But after about 3 days and a crapload of flashes I ended up flashing jedix20 and added the alexander theme..which suprised the hell out of me...the stock jedi had less signal bars like 1 or 2. I flashed alexander theme and my bars are from 2-4 with 4 being the best. Everything seems to be working. I had also did a test and made sure that my Network in setting was registered to the HOME network. That may have played a factor as to why the network wouldnt work even with signal bars. I flashed JediMasterX2 and ran across an issue like that. I flashed the att carrier files and it didnt work. Then I flashed the 7105 version and checked the Network operators and searched for a network. It pulled up AT&T and Verizon and when I chose AT&T and it registered my phone everything started working. I dont really like messing with the system files but I investigated the Jedimaster zip and looked under Jedi> carrier> att> and opened up the cscversion.txt under rb text editor and it showed an incorrect version. I317ATTAMA4....which im assuming was supposed to be I317ATTUCAMA4. Also under the SW Configuration. Xml the csc version was still the same. AMA4 it may be nothing but I would have thought it would have needed to match up. Ill have to look into it some more. I really want to update but hell idk. Might be done trying to flash roms on this device if everything works right
