Since yesterday the weirdest thing happens to my phone. For a couple of months I've been using MIUI 2.3.7c and nothing like this has happened. The mobile connection icon in the status bar has disappeared, as if there is no 3G signal. I check the APN, and it is all correct (my phone has been working normally until yesterday).
I flashed MIUI again and it was back to normal for a couple of hours, and then again, no connection. Flashed MIUI again and it was the same. Flashed Gingerbread 2.3.4 with Odin and the same.
What can it be?
Have you tried to do a full wipe/factory reset, clearing the cache and fixing permissions through CWM?
Yes, I did all that and nothing.
is it a signal problem or data connection problem?

Im new to flashing roms, so bare with me. I flashed my first rom last week, using Andromeda3 and Ursa Minor #2 kernel, everything worked great except, i couldnt connect to 3G/H, even though it showed up on notification bar, tried looking for answers, i ended up flashing different modems to no avail. So, i flashed back to stock eclair, used kies mini to upgrade to Froyo 2.2 UCKB1, Data worked. I then flashed UCKB2 rom, data didnt worked) i tried wiping cache and all that, still no data connection, btw, wfi worked. So i flashed back to UCKB1, again, everything worked perfectly. The other day, i flashed Fusion XI and GB bootloaders, i must say i like this rom very much, but again still couldnt connect to 3G/H, everything else worked, although i havent tested the GPS yet, i am getting amazing DL/UL speeds through wifi. Anyway, i searched XDA for any answers i could find and pretty much tried them all, seems like only KB1 3G will work, but any custom rom out there, data hasnt worked even though i see it in notification area, i'd use market and browser, but would say could not connect. Am i doing something wrong/ missing a step?? I really like Fusion XI and dont want to flash back to stock. Any help would be appreciated.
Didnt know where else to post this, seems like other people dont have the data connection issue :/
That's weird.
Try flashing the kb1 modem on fusion.
I did try flashing the KB1 modem, but that too, didnt work. it only works if i go back to stock KB1 for some reason.
where do you live? what Carrier are you with?
have you checked your APN settings?
fill in your location and carrier/ device info in your signature/ xda user information.
I Live in Southeastern Pennsylvania. And currently have AT&T as my carrier. I tried APN settings, but not sure what to set it too, i have used APN Manager from the Market.
Try resetting ur apn settings to default. Then reboot.

how do u reset apn settings?
Settings, wireless and networks, mobile networks, access point names. Now hit the menu key and reset default apn well be on the bottom left...
Ok, tried that, still a no go connecting to data. I just flashed stock 2.1 then 2.2 update through Kies mini, i no longer have data connection even on official stock roms could this be a hardware issue??? gps sucks. ran a gps test using the app from market. other than that, everything else is working. what did i do wrong?
Hi guys,
I'm being annoyed by my SGS about his data connection. Hope someone could help me!
Few days ago I flashed MIUI Mintberry 2.1.20 and everything was working like a charm, but this morning data connection switch failed several times.
I've tried to wipe everything, re-flash Mintberry and even to flash JVU stock with Odin, but I still can't switch on my data connection.
I can't even see any icon on the status bar.
Any idea? Is my phone broken?

Hmm this is strange, so you turned data on but theres no symbol, right? Have you tried installing another kernel (maybe also applying the Kernel Cleaning Script)?
I' ve tried everything with Odin, and at the moment I have a beautiful black screen of death.
Odin cannot recognize my phone... I'm very frustrated
EDIT: Upgrading Kies'drivers, I managed to connect the phone with Odin again, so I've flashed the lastest official stock firmware to check my antennas. In the worst case, I'll be able to go to the shop for assistance without problems.
Have u tried typin ur apn maually?

Sounds like a settings issue. Never heard of anyone have this problem before - I've flashed every version of mintberry including betas.
I just had this issue
I just had this and figured out what is wrong, its a easy fix too! Just go to settings and wireless and change the access point for your mobile connection. I had 2 access points and just switched it to the other one and my data started working again!
Hope I could help
Hi guys! thank you for all these answers!
I've tried to set APN manually, to change custom ROM and custom kernels and coming back to stock too, but still no data connection icon (neither data connection itself).
At the moment, I'm on JVO, the latest official italian firmware, everything is fine but 3g data connection.
Other ideas? Shall i need of Samsung customer service (I hope no!)?
Solved...
MIUI default settings fault: SMS notification has ran out my money and my provider has blocked 3g connection.
My phone is safe!
So I had some escapades today, I had my SGS running jellybean, then I tried to change the screen density and bang, bootloop. I panicked and after some odin fiddling managed to get it booting Darky using odin. I was in a room with no signal at the time so I thought nothing of not having any signal, even so I then went ahead and used recovery to reinstall my Jellybean rom since that's a bit nicer than the 2.3 Darky.
Long and the short of it is, I can search for networks in my options and it will find them, but when I tell it to connect to one it says "Can't connect to this network right now. Try again later"
I have tried later and surprise surprise it didn't work. I have tried installing a different radio, clearing the dvalik cache and fixing permissions as well as a few other things. Please can anyone suggest something, this seems to be a very uncommon scenario and it's stressing me out that I can't find any solutions.

Yeah I've checked them and unfortunately they all seem to be in order still, though there are a lot more settings than any website offers things to put in them
same problem
i am having this same problem on all cyanogenmod 7,9,10. i have tried many radio and modem flashes. i can scan and see networks, but i can never connect to them.
have you made any progress?
Problem is EFS folder which tends to do with IMEI.
To fix it you need to copy the backup EFS folder from your SDCARD to the root of your device. (/)
If you don't have a backup you'll have to ODIN back to stock and re-root....etcetera

thx
thank you for the response. I put it back to stock lastnight before bed so i will give this a try.
i have the gti9000m from bell in canada. I updated it through kies to 2.3.3 gingerbread and it all went badly. It would boot up and load to the os be on for a bit then reset. It turned out to be wifi problem, running it on airplane mode stopped it from rebooting. Then if i tried to turn on wifi it would quickly reboot.
So then i tired all the cyanogenmods, which worked it stopped rebooting all the time. however the wifi would connect and work for about a minute then it would drop. doing the
1.turnOn gps
2.turnOn wifi
3. turnOff gps
this would let the wifi work again for about a minute. I tried all the wifi fixer apk, and a bunch of wifi.zip mods, and then ping the router gateway constantly, none solved this problem. Very annoying because i need the wifi working for develpoment of apps. I have spent a great many hours on this problem. lots of people seam to have this problem but no solutions have wokred for me.
So, my questions are....
1. does your wifi work?
2. how the heck do i get mine to work?
back to stock
After going back to stock then upgrading connecting to network operators is fine.
wifi is still broken though
I flashed a JB INDIA official firmware via odin to solve bizarre 3g problem in i9070.
At first it seems the problem solved, because I saw the H/3g i next to the signal bar, I browsed the net....everything was just breeze....but just after two minutes.... ... the damn thing again happened.
I then reset to factory settings and cleared my cache nd all that , and I got fresh apn from my carrier,crosschecked net work availability from others..it was fine but when i activate the data network mode, the icon's missing again and the internet doens't work.
still 2g is working fine? this wiered thing happens with 3g(WCDMA ONLY) MODE.

I know , it wasnt tested on stock , but it should solve your problem
Hello all,
Just having an issue with my Z3 compact. The wifi keeps connecting and disconnecting every few seconds. This is a new development and it has never done this in the two years I've owned it. It finds the networks, connects and then promptly disconnects after a few seconds and then starts to look for networks once again.
Here are a few things I've already tried....
I have tested the same WiFi network with my S7 and laptop and they are stable on this network.
I have tried a different WiFi network with the same results
I have downgraded to a previous TWRP backup of my ROM when the phone was still stable.
I have changed the ROM completely with a factory reset and new custom ROM flash
None of the above has worked so far so not sure what has happened and if this is a possible hardware failure of the modem? Is there a modem file that could possibly be flashed?
Thanks for the help.

This has been mentioned several times in the Q&A thread, and @toxic-hero even posted a fix
Thanks Didgesteve,
I have tried the Legacy DHCP Client fix in the developer settings and I've also done a "Network settings reset" under Settings > Backup & reset before rebooting and still no help. The issue persists and I'm at a loss as to what the hell has happened here....
Same problem... I still have guarantee, so I flashed back the original up-to-date firmware and the phone was sent back to the local sony service, and I'm waiting for it.
