I just flash gingerbread on my galaxy s once rebooted it doesnt recognize my network, I make a network scan but my network Claro Puerto Rico dont appear.
Any guess or help??
Check your APN settings, if backed up, restore, reboot
Sent using TCP/IP
Check your csc code by either
Download nitrality from market and then go to tools
or type *#272*your imei#
Changing csc will factory reset your phone..
@ Talon: since Spetember edition, *#272.... is not making factory reset, just reboot.

You mean 2.3.5 onwards? ok thanks for letting me know.
Best to warn just in case though may not be on the latest yet
Yep, tested recently with JVR... no factory reset anymore
making things easier, isn't it?
EDIT:
originated from Click
I tried it on JVR, stock, odexed... worked without FR (speedmod kernel). Cf kernel, deodexed Ramad's ROM - worked without as well on JVS.
I'm not sure if some customized kernel/ROM will not cause the FR...
I just went to the phone company and they flashed from froyo to gingerbread 2.3.3 but still having problem the data icon stay still on letter E and start to flash on and off constantly.
When E flashes, it means, that EDGE network is available, but phone cannot connect to it. Usually, it means problems with APN settings.
Go to Setings - Wireless Networks - Mobile Networks and Access Points. You shall have some access points available. If not, try to ask your operator to send you setup sms or try so search on internet to find the setup rigth for your operator.

I've got an unlocked Australian (Telstra) Samsung Galaxy S i9000T that I've been using on the Optus network (with Amaysim).
I've run numerous stock and custom ROMs and recently backed up the /efs folder (using: "tar -czf /sdcard/Download/blah.tar.gz efs") after some scares with boot loops while trying to load a new Devil kernel with my TeamNYX RC5 Android 4.0.4 ICS ROM.
With these custom ROMs the phone identifies itself as an i9000 (instead of i9000T that it showed with the Telstra FROYO.JP8 ROM).
The other day the airplane mode became unavailable and I lost the mobile network.
I've tried going back to the original ROM (got it with Check Fus) and done factory resets etc but I still get emergency calls only.
I've tried swapping sims and my sim works in the other phone but no sim will work in my phone.
I've also reloaded my efs folder but nothing has helped.
I've check the "Australian Mobile Telecommunications Association" web site to see if my IMEI is barred/blocked and it's not.
Does anyone have an idea on how to work out whats going on and what can be done to investigate/fix the problem ?
This forum always had a search function. Web, tapalk or xda app has it.

problem would be due to branded phone, meaning you need a telstra ROM, for it to connect to telstra network.. try this https://skydrive.live.com/?cid=da77fff5eaaed269&id=DA77FFF5EAAED269!296 and its not easy to get one
xsenman,
I'm currently back on the stock Telstra branded ROM (obtained with CheckFus) but with the same problem.
Also, I'm not trying to connect to the Telstra network. I just trying to use Amaysim (via Optus) that has always worked before.
I'm guessing it's one of three problems:
- Corrupted EFS (but my IMEI is correct)
- A block that the Australian data base doesn't know about
- An actual hardware problem
I've tried a lot of things including have the phone re-create /efs and then I put the imei folder back.
I'm wondering how to track down the cause. I.e. is there a way to examine logs of why not able to get on the network?

O-T,
I've read that thread. That was how I backed up my /efs before this problem.
I was never able to get the /dev/block/st13 though and just have the efs folder.

If your IMEI, is correct, it is not an EFS problem, but has to do with network settings, try menu> settings> wireless & Networks>mobile settings,
If your SIM is from telstra, than don't use optus or other networks
you can try the ROM and CSC file form link i posted earlier

xsenman,
My sim is from Amaysim and worked before with the stock Telstra ROM that I've gone back to now. I've not tried your ROM as it looks like to be the stock one I'm using.
I can't access the "mobile networks" settings as the phone doesn't think I've got a sim installed at all.
It looks like a hardware problem.
Could this be a boot loader / radio mismatch ?
Also, is there any reason to not always use the latest version of Odin I have ?

Also could happen, IF SIM card is inserted the wrong way, cleaning the SIM contacts , using any Odin will do or try using another SIM card

You're right.
Problem solved. Amazingly the I9000 doesn't stop you from putting the SIM card in the wrong way round.
Thanks for your help.
Hi guys been searching all day when I can grab some free WiFi, basically I rooted my s4 gti9505 with auto root and then installed custom recovery, and flashed PAC rom. I'm unable to make calls or receive mobile data but can use WiFi. My settings say baseband unknown .. I'll attach a picture of my settings here in this thread. I have attempted to flash a modem/radio in Odin but this didn't seem to make any difference, the problem is I'm not sure if it was the right thing to do (didn't make a back up of my phone foolishly before flashing PAC rom)
I'd appreciate any help with this guys! My network is vodaphone UK if that makes any difference to any advice given...
Thanks in advance!

will do this too, have just finished flashing MGA modem twice using your steps, will flash rom again..i wonder if i should wipe/factory wipe as i would when installing new rom...ill try it!
no luck -still no network. im running out of ideas
network - unknown
mobile network type - unknown
imei unknown
imei sv - unknown
going out now for a while but thought id ask - do you think that installing official stock rom (perhaps from your s4 unrooting guide) would help flashed via odin? from searching i can see that some folk suggest that stock will reinstall everything i need...im hoping so, i really wouldnt mind going back to stock, anythings better than this

did you put modem in "phone" in odin?
hmmm weird! i guess your imei is not corrupted, sometimes while flashing rom in cwm, efs partition is not detected, so flashing modem twice should work
you can try with an other modem, use new one (but im sure to flash it twice)
another option is trying to flash your stock firmware

yes put it in "phone" mode, thats the second or third one i have flashed now so im not sure it wont help but for sure ill try again!
are you able to determine that its not corrupted? would it state as such if it were? im going to flash a stock firmware as a last resort. lost after that haha
edit - installed cwm using sgs4 flasher and re-installed my custom rom and gapps, booted no probs and network now working - sorted!! thanks for your help i dont think i would have reflashed the rom without your advice to do so
So I'm practically in the same boat. I'm currently on P.A.C. man nightly 09/18 (Vodafone Germany branded device). I never had similar problems, but now I can't call (or be called) and I'm not able to use mobile data.
I nearly tried everything:
1) I checked the IMEI (saved it before switching over to custom roms), but an IMEI number is still there.
2) Went back to stock to see if it's a problem of P.A.C. man ROMS or not. On stock it didn't work either.
3) Went back to P.A.C. man ROM and flashed modem XXUBMF8 via Odin 3.04 (from this thread: http://forum.xda-developers.com/showthread.php?t=2192025)
4) Flashed the modem again after I flashed the ROM because it didn't work either.
So I'm completely lost now, I really don't know what to do next. I had mobile data for a couple of seconds every now and then, but nothing stable. And since the problem came up (yesterday evening) I can not make any calls at all.
Can someone help me?
Edit: The very strange thing is that I have full reception balks in the notification area (only in grey). But still, I guess this means that the device is somehow able to detect a signal but can not connect to it?
Edit2: I apparently have no Device-ID. May that be a problem?
So I took some screenshots to show you guys my problem a bit better. For some reason my mobile data now works (currently HSPA, but it's extremely slow). But I still can't make any calls (or get called too). =/
Edit: So to sum this up: the strangest thing about this problem is, that even when I go back to full stock I can't make calls. =/ What could be the problem? An IMEI number is present in the settings (althouh the 'IMEI SV' under 'About phone' --> 'Status' was one digit below the current one that I can see under those stats). The whole problem makes me believe that my provider can't sort my phone number to my device (I'm on Vodafone; but if that's really the case: why the hell does mobile data works sometimes?!). The other possibility: something with the modem/radio is broken. Could this be the problem? The thing is that I also tried to flash a custom modem, but the problem is still there...
I'm really concerned that my phone just became an expensive paperweight
Slightly different than my problem in that I didn't even have any bars for reception..my problem was fixed by changing the custom recovery software (originally I used philz to flash PAC), But I flashed cwm and then used this to again flash PAC, and all was good..don't ask my why but it helped me so you might want to try this...

Thank you for your answer!
You also flashed a different modem didn't you? Did this help or was it only the custom recovery? I'm confused because I used CWM before and never had problems. But then this mess all came up...
Yes I flashed several modems, that didn't help..only using a different custom recovery to flash my custom Rom again helped..hope you get sorted!

So I tried to flash PAC with TWRP 2.6.0 (it worked before), but the problem is still there.
I'm really confused. I really don't know what I can do or try to fix this mess... Is there some USSD code or something to find out if my device is missing some ID codes or if the modem is messed up or something?
Edit:
Update: For some reason I now can receive calls/SMS but only when I'm on GPRS speed. Outgoing and ingoing calls are no problem then. When my device is on HSPA or HSPA+ speed however, the old problem of not being able to call or be called is back. On one hand it's good that I'm somehow able to make calls again on the other hand it gets stranger and stranger. I know that it's a bug on PAC man ROMs that you can't change the mobile data speed options (LTE/HSPA/GPRS etc.), but I think that this could be the problem (or at least a part of it)...

Actually I can change the data in my phone between 3G and 2G (don't have LTE support here in my country)
Have you checked your APN? Think that might be a problem.
Also please post the steps you take before flashing PAC (ROM, kernel, recovery, etc)

Within Wireless & Networks --> Mobile Networks --> Network Mode? On PAC? It always crashes when I try to change something there. In the PAC bug post this seems to be a known bug, my mode is also set to GSM/WCDMA/LTE. But whenever I enter the settings to change this, only 'LTE' is chosen as option. I don't have LTE on my plan and I read somewhere else that Vodafone has major problems with it's LTE network here in Germany and that it may be better for customers without it to turn it off.
About APN: there is definitely something strange. I can enter the settings and I see three different APNs that were not created by me (they must be the standard carrier ones): they are called Vodafone DE (for Germany), 1und1 (pretty strange because the settings are the very same on this one, only the name is different) and Vodafone DE-MMS.
The strange thing now is that I can't change any value of the Vodafone DE APN... When I go into its settings, everything ia greyed out. This was the same on the stock ROM...
Now when I create a new APN with the correct provider settings (found via Google on the VF homepage), the phone still won't work. When I put the device aside for a few minutes, the Vodafone Deutschland DE APN is the selected APN again although I never went back to it...
Is there some option to take a deeper look into the modem stats to see what's the problem?
Install stock ROM

I tried that already, but it didn't help. Same problem...
I factory resetted the phone, wiped cache and dalvik cache and then flashed my Vodafone branded stock ROM via Odin that I had on my device when I got it. Didn't help for some reason... But: should I also try to go back to stock ROM via KIES? I haven't tried this method until now...
Edit: About my flashing method: I went from the stock ROM to rooted (via CF Auto root with Odin). For PAC I then flashed TWRP 2.6.0 and then in recovery factory resetted the phone, wiped cache and dalvik and then installed PAC. After that I installed GApps. I used this method before and it worked without any problems...
Edit2: I found this thread, it appears to be the same/a similar problem with the S3: http://forum.xda-developers.com/showthread.php?t=1805709&page=6
Now is there something similar for the S4? I think I tried calling ##72786# on stock ROM and it didn't work...

Delete the unused APNs.
Do you have mobile data?
Also I asume that you're running the latest vertigo's build, because with me GSM/WCDMA/LTE is always selected.

Sometimes I have mobile data, but only for very limited time; for the majority of time, I don't have mobile data and can not make calls.
I also tried to delete the unused APNs, but still no change =/
I tried to use a different Micro SIM in this device, but the same problem appears. No data, no phone although I have grey reception balks.
any update on this one?!
I know this issue has been spoken of in other posts, but nothing exactly like the issue I am having and all I have read are not with the s4
I am on factory stock Rogers firmware. I337MVLUAMG1 unrooted. "Not registered on network" is keeping me from doing anything. I can access wifi and all my APN settings are correct. Nothing in my phone looks wrong or out of place.
I have tried 2 new sim cards and that certainly isnt the issue.
My imei and serial are reporting a.ok
Phone was unlocked from rogers and previously being used with bell all with no problems.
I did try some custom roms before heading back to this and thinking perhaps something got screwed up. I inserted my sim after installing omega rom v11 and it has not worked. that was the first time I even tried a sim in the phone. So it has never worked since I got it. Which sucks because I don't know if it was something I did or something that was already in place.
I have done a factory reset with data from settings in the phone and also from stock recovery.
I have removed the battery, sim and restarted. Doesn't help.
Phone says "not registered on network" when trying to make calls and says unregistered sim card when dropping down notification bar.
Any ideas? Help? ahhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh
Edit: Ok, after some heaving reading I think the issue lays with the update to Omega v11. I think it changed the efs file structure to a new format and I need to use a newer modem to access it the new format properly.
Can anyone please let me know an mg4 or acceptable modem that would allow me to test this theory and if I can just flash the modem with the stock firmware.
Once again its an i337m currently running rogers I337MVLUAMG1. IMEI + serial working fine but no network access. Looking for a modem that will work with this setup to see if I can access a modified efs folder.
Information of modified efs was read here - http://forum.xda-developers.com/showthread.php?t=2377731

If you are reading this and never done it... DO IT NOW!
It is a simple thing to overlook. I have been flashing roms for over 2 years and not once have I back it up... New S4.... not so good. Just sent for repair.

Check if your sim card is seated properly. If that doesn't fix it try a factory data reset from the settings menu. Still no luck then Odin back to stock NI2. If after that it still isn't working contact Verizon with your stock phone, it may be a problem with your phone or with them.

no good. I bought the phone on Ebay, and it is currently using Page Plus. I tried rooting and flashing a custom rom, to no avail. All features work other than calls. Data and sms wouldnt work if the sim was unseated.
