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.

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!

Data issues back and worse

OK So I was experiencing data drops frequently. I disabled the battery app that came with Project X and updated profile/PRL and it seemed to help. Well after a few days it came back and now its worse than ever. Started getting a small box that popped up saying "Network error, please check connection" or something like that and now I have no data at all no matter what I do. Any ideas? I am thinkin I should just return to stock.

What modem are you running? Try flashing the latest GB27 modem, updating prl/profile, see if that helps.

Are you sure it's not your area being effected? Try calling your provider to see if there's an issue in the area first. No amount of trouble shooting would help if that's the case. That happened to me once on metro pcs and I was going crazy trying to restore then I find out the service was messed up for a few hours.

If after doing this, your signal doesn't improve, and you're positive there's no network repairs, maintenance, etc.. Then I would reflash the full restore one click of your choice (Make a backup to your pc as it will delete your internal memory) and update PRL and profile, then flash the rom of your choosing. Now when you put things back on your device do not restore any system data because it will bring your issue back!

[Q] Signal but no data ony any ROM

So a few weeks ago I installed the new 4.3 leak and everything was working fine. Then about 2-3 days ago, data stopped working. I've since fixed permissions, wiped data, flashed AOKP, Odin'd back to stock 4.1, and then down to 4.0.4 and then used the *2767*3855# method of wiping.
Nothing has worked and I have no idea what could be the problem. Can anyone help out?
Luckily I have an upgrade if I can't get this working, but hopefully I won't need to use it.

So my IMEI isn't corrupt. And Ive tried rebuilding NV data. I've tried pretty much everything in all the assorted connection issue threads.
I get an IP address from ATT but still have no connectivity.
Anyone?
Sent from my SGH-I747 using XDA Premium 4 mobile app

Had a similar issue a few weeks ago. I have a att s3 unlocked to Tmobile. Only rom in could get data was miui all others wouldn't work. So I copied the apn settings from miui and tried them in another rom and worked. All that was missing was the hyphen in T-mobile. Try finding someone else's attention phone and see if the apn settings are the same.

Just set the APN settings to be the same as my wife's phone. Still no connection. I get full sign with the LTE indicator, but it never gets a connection.

So, weird thing... I turned data off for like 24 hours. I just turned it back on to show my wife what was going on and....magically it was working again
I don't get it...

Last time that happened to me, I just reset my APN 3 or 4 times with a reboot in between each, and eventually it worked. It's kind of a squirly thing to deal with.

*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

Are you really on straightalk like your profile says? Have you checked your APNs? You've been bouncing back and forth I'm wondering what's in there. Sounds like something in there is not happy.

My apns are fine and have always worked. The problem is not with that but rather signal strength, being able to make and receive calls. Messaging and data work fine.

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.
Thxs

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

Would the phone having factory test and factory mode on the phone affect it any. I seem to have 2 factory mode apps with one being 560kb and the other 84kb. I don't know if those could affect the signal performance
