I think after I have installed a 2.1 android rom (I guess it was Kagudroid's) and switched back to MCR3.2b5 (with wiping of course) location determination via gsm cells broke down. I.e. Google Maps and all other apps are unable to determine my location based on only the gsm network (not wifi / gps).
Does this sound familiar to anyone? Wiping one time or another doesn't help me to fix this issue.
I know even put back up the original 2.73.405.5 rom via the RUU. So I would think that everything would work again, since everything is original again. No luck.
Could this mean a hardware failure?
don't think so, unless you don't have any signal at all?
have you tried upgrading to / reflashing the latest radio?
Yep, tried that as well. Doesn't help me. This really annoyes me.
never had this happen sounds a strange one. on your so list is network location app installed?
none of the 2.1 ROMs have the cell location working properly.
Have you done a wipe since you came back from 2.1? If not, there may still be some bits from the 2.1 hanging around somewhere.
As mentioned in my topicstart I did do a wipe. However I have already determined the cause of the problem. It is the provider. Checked that with an other SIM. Furthermore I have come to the conclusion that changing to 2G mode also resolves the problem although I definitely don't want such slow internet (plus changing to 2g is not possible on mcr3.2). I'm gonna contact the provider to see what they can do. Likely that they're having problems with the gsm antenna coordinates after all... Thanks all...!

Hey, all...
My Vibrant was working fine after the latest firmware update (GPS gets multiple satellite locks in moments), but now it refuses to update my location via cell towers unless I reboot. It still updates my location over wi-fi and GPS with no problems. I tried doing a factory reset to see if one of my apps was causing the issue, but no dice. I'm just running the stock firmware on a US Vibrant with no mods/ hacks. If you need more info, I can certainly do my best to provide it. Be gentle... This is my first post
Ideas?
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.
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.
PS: Hope my mail is clear enough, since English is not my native language...

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?
I have read thru a few threads, but they all vary so I am not sure if this is the same issue so i apologize in advance if there is a thread with an answer somewhere...I certainly hope it is not a hardware issue!!...ugh..
I recently flashed Nottach's ROM to my Atrix 4G (excellent ROM!) and was in the process of loading apps and "fine tuning" it to my style and preference when I noticed that my WiFi, Bluetooh and Data are no longer working. I didnt install anything other than a couple of apps that I have been using (GoLauncher, ADW Locker, etc.) so I am not sure why everything stopped working.
I can still make and receive calls and text messages, but I am unable to connect to WiFi ( it sees WiFi signals but it doesnt get past "Obatining IP Address"). Bluetooh enables and disables right away. And I dont see any activity from the Data icon.
I have tried reflashing the ROM, Factory Reset, Wiping Partition/Dalvik, Resetting Permissions, etc. but none of these seem to have an effect on the issue.
I have seen other posts in various forums where some one mentions similar issues and they talk about flashing the antenna via RSD to get it to work, but links to the antenna ROM all seem to be broken.
Any help in getting this resolved would be GREATLY appreciated!
FYI - My phone is Unlocked and I believe it is still Rooted.
Thanks!
Well.. after playing around with reinstalling the ROM I set the Kernal back to Stock AT&T and everything appears to be working again.
So I think the fact that I was using the Faux 1.3Ghz kernal may have caused the issue, which is odd since everything was working fine for about a day before the problem started happening.
Oh well.. i will play around with different kernals to see if there may be a compatability issue some where.
Hopefully this info helps others.
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.
