Problems with 3g / data connection - Galaxy S II General

Hi,
I have lighting rom 6.1 installed XXKH3 (what this means?? XXKH3??), I have a Samsung Galaxy from Portugal and my 3g / data only works when I do a factory reset and in next boot it goes away. Even if i try to create an APN it crashes when i select New APN. I tried to change the CSC to TPH (portugal) with the *#272*......, also installed a MultiCSC OXXKE2 because the lighting rom didn't bring TPH, and also copy the CSC portuguese files with a .zip in recovery. First time after selecting TPH in *#272 everything works good, but next reboot stop working again. I checked with *#272 that TPH is selected and i don't understant what is happening. Please help because i can't use internet.
Thanks,
Raven

i have the exact problem!! Cannot figure it out...
Same Rom, same kernel.
Flashing another ROM (wipe) doesnot solve the problem... Aiaiai.

Have you tried flashing other modems?

Galaxy S from Greece

Hello
My SGS is originally from Greece (simfree)
with the default rom it came with, after factory reset the language/locale was set to Greece.
I flashed to rom JM2 from here
http://samsung-firmware.webs.com/samsungi9000.htm
and updated all component (PDA/PHONE/CSC) and also repartitioned the phone.
and still, after every factory reset the locale/language is set to Greece.
of course I can change it manually, but it's a little bit irritating
Can I change it so English will be selected after every flash/factory reset?
why does it select Greece even after I flashed other roms?
TIA
Maybe its your sim card?
No, the sim card is Israeli
what else can it be?
After flashing another rom I noticed that after the flash process
the system installing update.zip although I don't have any file on the internal or external SDCARD...
I tried to search for it with root explorer but without results
where can it be and how do I "solve" this?
TIA
I found something
no matter what rom I flash, I always get this file in /system/csc/cos/csc
it's coming from sort of update I can't find on my phone
this is your productcode ...

change csc in Darky 10.1 advice please :)

Originally flashed JVH from samfirmware.
Flashed the Ficeto_JVH base and then Darkys as normal
Can't reset the csc within Darky by using the normal methods and also tried the same when on Ficeto_JVH before flashing Darkys, but as with Darkys, you only get the current csc (xee). My normal sales/area code is cpw(o2 uk)
I can't send or recieve mms and I have manually changed the apn settings. Internet works fine.
Had the same issue whilst on Simply Honey but that gives you a multi region csc so you can easily change it. My mms's then worked fine but I do like Darkys so I'd like the try and sort the current issue if someone wouldnt mind advising me
Thanks!
No one know?
How about flashing a jvo csc over darkys using odin? Bare with me here lol
For the benefit of anyone else ever wondering the same thing...
Flashed it anyway.
JVO oxa csc only through odin.
Phone booted up. Opened csc selection in sgstools. Gave me the full choice.
Installed cpw csc. Rebooted. Works perfectly and I can now send and receive mms messages.
Hsppy days.
cc
If you have a exiting CSC folder, copy it with root explorer to system/csc
If the csc not exist, try to modify all CSC files in the folder with a hex editor.
And replace your product /CSC Code e.g. you wish DBT and you have the XEE folder.
I hope you understand me and it works.
happy luck.

No network Available

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.

GT-i9505 No mobile network/data after flashing custom ROM

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?!

No signal [FIXED]

The problem got fixed a year ago.
The problem was the hardware and not the software
I've replaced the corrupt phone.
how you changed csc as u explained? usually flashing a diferent firmware with another csc will completly wipe the phone a d restore efs info, be sure ur flashing a different csc not included in the original csc pack (oxm and btu r the same csc for example).

maybe thats the problem, ILO and CEL r both the same CSC (OXM), if you dont flash other CSC it will not completly wipe the efs carpet, try downloading BVO from sammobile and flash it.
before flashing twrp or anyyhing first try your signal with completly stock BVO.
is wifi working ok?
had problems with my first s8 regarding gsm/wifi signal, got it exchanged to get it to work(it was stock untouched)

after a full clean flash of the official firmware go to factory reset from the phone settings, if that doesnt work im out of ideas, but after a clean flash, do all the process without the sim card and put it after the factory reset

After a minute without doing anything suddenly, my signal is back but it crashes every time i use it like to answer a call, i guess my antenna is defect, i will return my phone for a replacement.
Hi, have you been able to solve the problem? It happens exactly the same
Yes i have a similar problem, apps crash, phone lags all the time. I use 2 bluetooth devices connected all the time, location is always open, nfc is disabled, i use nova launcher prime. Phone is not rooted. Call drops when there is no reason. Cellular signals complete goes away even though it was at full service a moment ago, then after 10-15 seconds, it comes back again. This phone is making me really sick. I was using galaxy s5 before this and it had a better performance than this one. I have galaxy s8 g950f by the way.
