The Edge symbol in my Galaxy S2 disappears when the signal is down.
It never reappear when the network signal get back. Even If i change all settings... tried disable/enable "Use packet Data" and other settings...
NO USE! It seemed to be serious and consistent bug.
Hi balavj, maybe a silly question, but are you sure that you are in an area well covered by edge gprs signal?

Signal drops inside a room... when i come out of a room... network signal regains... everything works... data connection symbol does not come back... this is the exact problem... only after reboot... it resolves
Ah I see... Never met these conditions with my phone here, so sorry I can't be of much help.

i am having a similar problem, seems to have happened quite recently for me as previously i had no real issues with it at all.
I keep having to reboot my phone to get a mobile network connection, otherwise the Mobile Network Status shows as connecting all the time...
Very strange
Try other modem, or shove the phone into airplane mode and back again should kick it back onto data.
I have the same problem here...
Tried KE4 (Original), KG7 and KH3 modems e nothing..
Tried many roms too, and nothing, the problem is on all of them...
Data on/off, Airplane mode on/off, nothing gets data working back, only reboot...
Ps.: ROMs tested: Lite'ning, Cognition, Exynos, KE4, KG7.
Kernels: Niphetamine, Jeffrey, Speedmod
SAme here
same here...
Is anyone still experiencing this?
I was having major issues with connectivity, data and calls. I got to the point where i could barely make or receive a call or connect to a mobile data network.
I tried numerous modems and firmware, including original O2 carrier branded firmware, generic firmware and custome ROMs. I found the problem replicating across them all.
I finally settled on Crsikelos ROM (V14) with KE7 modem, however i had previously done a full wipe install of my original O2 firmware (XWKDE i think) and tried a couple of different modems (KH3, KE2 and KE7).
I even tried removing my SD card as i am convinced my sd card is not compatible and is causing issues...
All of a sudden everything started to work again?? I put my SD card back in and left it in, no chance everything was still working. So then i flashed Criskelos Rom and made sure my modem was KE7, that was about a week ago and it's still all good.
TBH i think it may be something to do with O2's network being pants (rather than my SD card )....
Not sure this will help but i thought i'd post my experience for you...
Hope you get it fixed
i have the same problem i.e data loses connection. after a fresh flash of stock rom and factory reset , it starts working fine for a week or so and then the shyt happens again . i can tell u , its not a hardware issue, it more like a software issue.
i m not good at android but wen i used to run squid on a linux machine as a proxy server , i recall i had to clear a log file to make data flow possible every few days. i think android has a similar issues some logs files build up or some **** like that.

Hello everyone, i'm asking this because it's the third time i had this issue. I often keep my Data Network Mode deactivated and turn it on only when i need because of my 3g plan (quota, taxes, and also because it's likely to find a WiFi network in the places i usually go).
The problem is, sometimes i turn on 3g (by Phone options menu) and... nothing happens... i need to reboot to make it work again.
The 3G network in my country is quite unstable, but i'm pretty sure that isn't a signal problem because one of the times i was turning on/off the 3G to make it work and i gave up and forgot to turn it off, the next day when i tried again i found it was On but not connected. After a reboot, working again.
Anyone having this issue who found a fix? Could be a problem with the kernel or app?
Edit: I Forgot: CF-ROOT Kernel, KF3

mate i am afraid you have answer already - "The 3G network in my country is quite unstable"
that can clearly produce the bug. Just in the case check your APN settings if they are correct. Settings- wireless and network-mobile networks- access Poin Names - compare the stats there with your network provider and make deep research.
just example i am on vodafone - i found that i was running vodafone live profile in APN and i was loosing conexion and i had troubles loading some pages - after research i found that there is another setup for vodafone as well - different then the live but for vodafone as well. i am using it since then and i am experiencing now the lighting speed of 3g. Just give it a try.
Searching on the internet i found that the configuration of my APN is equal to the recommended.
Backup data and factory reset phone should clear any software problems .
You could try flashing KH3 modem .

Same issue here for both rooted and un-rooted GS2
Retracted - will have to do more testing
Hey guys i got a problem.
After flashing my phone normally with Odin like usual all of a sudden data connection aint working anymore. I works fine with wifi, but not without.
It shows 3G/H signal in the status bar, and i see the upload arrow is blinking so it is sending data, but not receiving anything.
I tried googling it, tried flashing various different roms that worked before and original firmware, but nothing helps so far.
I checked the provider info in the phone, and its all correct.
Kinda lost here, hope someone has an idea how to fix it
thx in advance
nobody? i tried everything so far and dont even know why its not working anymore
It's going to be difficult to get much help here because I don.t think most developers have had time yet to get into the innards of the A501. Have you tried flashing back to the original stock ROM? You did back it up before you flashed it with a custom one right?

No nandroid backup, only titanium backup since i never had problems before.
I tried flashing all kind of original firmware now, KH1-3, even older ones, the latest. tried all custom roms that worked fine before.
Tried different sim cards, readded the APN settings etc.
Found out now that 2G is working, but as soon as i switch to 3G etc it shows the signal for that, i see upload but no download, so it basicly stops working.

(Instead of quick reply, i hit thanks first!)
Dial *#301279#. If it doesn't work, dial *#*#301279#*#*
Select 2nd option (Change HSPA revision or whatever).
Then select 3rd option (Release 6).
Restart.
Also, check your APN settings.
Use an app called Tweakker which will configure your apn if u dont know exact settings.
thanks for the quick replies guys.
so i did play with the codes today already, the option you stated i tried but sadly it didnt change anything.
HOWEVER i did choose disable HDSPA completly now, so i am on 3G only and guess what, now it works!!
Speeds are not what they used to be at this location, but that might be due to my data limit so i have to check.
With other codes i found out that while being on H/H+ phone didnt download 1 byte, so i have to wonder why.
With 3G it is working now, but what could the cause be. Used to flash quite often and it always worked, so not sure if thats even related to my problem atm.
Any idea what might cause the H stuff not working at all? I read about the SII getting stuck on H+ etc. before, but all the tricks with rebooting or toggling flight mode etc. didnt work for me
so far, thanks a lot!
Try different modems. Depending on ur location and service provider, atleast one should work right. I'm using KI3 modem without problems.

modem depending on location and provider?
i tried several modems from the original firmware thread under development. they all used to work fine before, now they dont. KI3, KI8, KH3 etc. all nothing :/
Hmm strange. May be you should delete all apns, and configure a new one for your provider.
Also give KG5 and KG2 a try.
i am having a SGS2 with KI3 and sensation rom 1.7 with kernel siyah 2.0. after doing this i am also facing a problem with my data connection. it works but its on / off.
can you suggest come remedies like now please .............
Hi,
I posted this query in another forum, did not get any response so posting here too.
I have tried searching the www for this but not getting a good answer that will solve my problem. My samsung galaxy s2 has stock android gingerbread 2.3.3.
When I stay in a wifi network long enough and then I move out from a wifi network , 3G/data does not automatically enable. However long I wait, there is no 3G connectivity. HSPA/3G icon does appear sometimes but there is no "actual" connectivity. I have tried going to "flight mode" and back, tried disabling/enabling data network, nothing seems to work. Only a hard restart to the phone works and when it boots up next time, 3G/HSPA connectivity is just fine. And the problem repeats itself whenever I go back to a wifi network and come out.
I took my phone to customer care, they re-installed 2.3.3 and it seemed to work for sometime. However after a few days, I am back to square one. I tried the MMI *#9900# which disables 3g fast dormancy, did not help.
Any solutions ?

Flash 2.3.6 and latest baseband..tat wl help..
Sent from my GT-I9100 using Tapatalk
same problem here
Did you get your problem resolved? I have the exact problem. When i move away from wifi area i see the data connection indicator 3g or h, but there is no real data connectivity. Toggling data connection off and off seems to make it work again. I did a factory reset and updated to the latest firmware but still no help.
Well, Using Odin re-installed firmware I downloaded from android soul. It was a slightly different version: I9100XXKL1_I9100OXAKL1. And since it had a pit file I re-partitioned as well while using Odin. It worked well, but phone had frequent reboots.
Took to the service center; they initially claimed that is how it works on all galaxy s2 phones and is by design . After much detailed explaining, I told them to just load the latest firmware for the phone. I am currently on:
Baseband: I9100DDKL1
Kernel Version: 2.6.35.7-I9100XWKL1-CL809037 [email protected]#2
Build Number: GINGERBREAD.XWKL1
It's been a day and the wifi to 3g switch happens seamlessly. Let's hope it stays that way for good. Will update in a couple of days.
Hi, everyone.
After a slight fall, my S5830L started rebooting randomly. In some cases it just shutdown.
Looking for causes, I've found that when Data Connection is active ( In Settings - Wireless and Network Settings - Mobile Networks) it reboots.
If I turn off Data Connections everything is fine. I even can connect using WiFi when available, and synchronize accounts, send emails, access market, etc. All OK.
When I check again Data Connection option, sooner or later (rather sooner) it fails again.
Has anyone heard about issues like this? I need some help to deal with it. I can use almost everything, except data connection, and I really miss it
Thanks to all for the answers, any idea is welcome!
Augusto.

Hi, this is not normal, what firmware do have you installed?
This problem may be occur with any program installed and not for firmware problem.
I've flashed at least three different firmwares and with all the same problem persists.
Right now i've Android 2.3.6 (from Entel PCS, Chile)
Kernel: 2.6.35.7-perf- CL771662
Compilation Number: GINGERBREAD.UBKPL
Baseband Version: S5830LUBKPL
The problem started after my son dropped the phone downstairs, just a couple of steps, though...
I don't remember installed anything wierd, for that time.-
PS: I took the info about Entel PCS version from your web. Thanx. Nice Job!
I would have to agree that it sounds more software then hardware based. Usually if hardwares broken its very predictable. I would try to restore a different firmware stock or custom. I have an L and went with a custom rom. The data dropping might be a baseband issue but someone more wise than I would have to comment on that.
The wierd thing is that on the first connection it works, at some point the connection hangs, then while trying to reconnect it shutdown.
I was running a Samsung's 2.3.4 firmware when the problem started, then I flashed a Personal Stock 2.3.4 firmware (the original, that came with the phone), after that tried Entel PCS's 2.3.6. I keep this one because it's the newer version...
All behave the same way. The baseband should be the same for all, because the L (S5830L) is for LatinAmerica, and I've always double checked this.
Hi,
Have you tried to flash the original stock ROM again? You can download it from http://www.sammobile.com/firmware/
This site also explain how to use odin to flash the firmware.
My Android version is 2.3.4and Baseband is S5830LUBKPF and it works OK
I believe it might be hardware wise. Have you rooted you SGA already?
Hey everyone,
I did a clean flash of OOS 2.2.1 a week ago. Now every time I go out or disconnect from WiFi, the LTE triangle always shows an "!" and I have no data. It's kind of a pain because I move around a lot and I have to keep toggling data or rebooting.
Is anybody else having this issue? I tried flashing a new ROM (CM13) but the issue still persists. My APN settings are correct, so it's definitely not that.
I've actually experienced this too on CM13.
I was about to create a thread with just this issue. I thought I had experienced this before CM13 updates, but not sure now.
Basically, when wifi connection is off or lost, mobile data will not work.
I have yet to actually work out the permutations of what causes the issue and the actual fix but essentially it goes like this:
Apply new ROM with clean, 'by the book' install.
Wifi works fine.
Disconnect wifi and mobile data doesn't work.
Check settings, all appears OK, but click data off and on again etc
Reboot
Wifi and mobile data work as expected.
Now that's at my home!
Leave house and mobile data doesn't work.
Check settings, all still appears OK, again, switch off/on etc
Reboot
Wifi and mobile data work again fine.
I have not conducted a proper scientific analysis of this, but I am wondering whether it's to do with changing radio towers. Once configured phone is good until new radio tower encountered.
I have just installed a new ROM and fixed the mobile data issue at home. All seems great.
Next time I go out I will see whether I lose mobile data if the radio tower changes.
I have tried about 6 different ROMs and all suffer the same issue.
I have become so frustrated with it that I am even considering changing my phone.
Okay so I fixed it but I'm not sure what initially caused it. When I clean flashed from 2.2.0.X to 2.2.1 via TWRP I started getting the issue.
However, I got it to work by reverting back to 2.2.0.X then updating to 2.2.1 via OTA. No longer having issues with data. Though I haven't flashed any CM13 ROMs so I can't say those work properly.
Not sure what went wrong initially, but it must have something to do with the radio. Hopefully this helps everyone else who is having problems.
