Well, just as the title says. I have an I9000L in here that has no signal. Thought it might be an issue with csc files since it was updated to ICS, but then i flashed it back to gingerbread and nothing change. I used the stock rom with no luck, problem is that it shows imei, baseband and everything in place. Thinking it might be a hardware problem to this point. But i oppened it and everything seems in place. Just wondering if it may have a burned baseband chip. But then again it shows the baseband version so my guess is thats not the case. Could someone help me on this???

Check your network settings
menu.settings>wireless and networks > mobile networks
or try https://play.google.com/store/apps/...SwxLDEsImNvbS5ha3ZlbG9uLnNpZ25hbHRyYWNrZXIiXQ..
Nope, no luck with the apk. Neither checking network or anything like that. The phone will just not allow me to do so. Like i said, the weird thing is that everythin seems to be working fine. I have an efs backup so i deleted the nv_data.bin to check if the phone is creating a new one and it is. It shows baseband, imei and everything. im starting to guess its a hardware failure but then again. The phone is almost brand new. I mean it was bought not too long ago. It was unlocked, and after flashing it shows multiple csc contents. I have fix something similar to this by applying the PCT csc(Claropr csc). But this time nothing is working...
The reason you didn't have a signal on ics is probably due to the fact you didn't flash a modem from here http://forum.xda-developers.com/showthread.php?t=1158783
[CM7/MIUI/ICS/CM9][06.01.12] Modems + Bootloaders(MD5)
So it might be worth going back to ics, doing that to get your signal back, and then reverting to Sammy Rom to see if that sorts it....btw there are no csc files on aosp/cm9 Roms
Okay thanks M8, one other thing. Initially the phone had signal on ICS. It was DOCs ICS if i can remember. I think that custom firmware will flash a new modem? Or not? And is it possible that it had signal and lost it because of that? Anyways thanks i will give it a try then....

Some ics Roms do, some don't, you can always flash another in recovery of the one that comes with Rom is no good for your region
ALWAYS make sure you are using the right radio for your phone. It solves many network issues
Ok then so i guess it might be a hardware issue if thats the case. Because i have use that rom before on a i9000 and never seen something like this. Hummm! Ive done just about everything and i cant still get signal. Goshhh! I rather have the phone showing no baseband or something than dealing with this....
You have checked your apn settings haven't you?!
Yeap M8 APN settings are correct. But in fact APN settings have nothing to do with the cell phone signal in terms of calls. If your phone is working it will receive the signal. The APN settings as far as im concerned will just set the internet and mms settings. Maybe with them set the phone will try to reach the towers(Antennas) but anyways the APN settings are correct.

Hi, I bought a Cappy in december, I rooted, unlocked it (I'm not in the US) and installed Cognition 2.3b8 first, then moved to 3.X, everything was perfect, but yesterday I started with dropdowns in data service then the whole service, I have signal (changing to out-of-service), but I can't make/receive calls, send messages or get data connection, today I flash the phone back to stock and even in stock I have the same problems, also I already try different modems without luck.
Is this a hardware issue?
Thanks!
Give this a try

Thanks...but I know how to install a custom ROM, I already tried Serendipity, Cognition and changing Kernel to SpeedMod and Firebird and different radios (ZNKP1, JK4, JL2, JL1, JL3) and no luck
Have you confirmed that your phone is still unlocked after flashing back to stock?
Check your IMEI number to see if you don't have the generic one.
Check product code to see if it's not botched also.

Well, after installing stock, I insert my SIM back and did not ask for the unlock code, so I assume it's still unlocked.
My IMEI is the same as in the box and IMEI SV = 01
Where can I check product code??
Try *2767*4387264636#
Thanks! Product code is SGH-I897ZKAATT
Everything seems right, if I had to guess... It's more on the unlocking issue after you flashed Froyo with your network.
Try referring to this: http://forum.xda-developers.com/showthread.php?t=831569
I just checked network status screen and everything is off, so the phone it's unlocked :S
Sorry I can't provide you with any more help brotha.
You don't have a corrupted nv_data.bin file, which is good.
Your IMEI number is correct, which I suspected first, cause there were discussion of the generic IMEI number not working on other networks besides AT$T.
Since it doesn't matter what rom, kernel, modem combination you use with no avail.
I would wait to see if someone else chimes in here that might have other ideas.
Things I would do though: Call to see if there is any outages.
Update through kies to see if you get service from the update.
Hope its not hardware related.
Sorry again and good luck. I will keep on searching for ya though

[Q] Just bought a captivate, No Signal is displayed and baseband version is "unknown"
Please, I need your help, I just bought a Captivate for my GF, we live in Honduras, Central America and the phone was supposedly sent unlocked, she inserted the sim card and the phone did not asked for any code, but, it has no signal, it is currently displaying "no Service", and when she goes to look at her baseband version, It displays "unknown"!
It has a crappy ICS rom, since Im an Nexus one owner I dont know a thing about this phone version!
Can you PLEASE! help me?
Can I just flash a CM nightlie over this ****ty ICS rom?
Do I have to upgrade or downgrade anything else?
Please, any help is welcome!
I assume you probably have, but are the APN settings correct?
You can probably flash a CM7 nightly over it. Worst case, it doesn't work and you have to flash back to stock first and try again.
It sounds like you don't have a working modem. If flashing CM7 doesn't fix it, flash a CM7-compatible modem and see if that fixes it.

Lolz good advice...just in the wrong order...
I would flash the modem first....cause it is the least invasive (doesn't wipe anything) and most likely will work.
Roms contain modems, so if fishing as ROM didn't fix it fishing a modem after that is just spinning your wheels.
BUT, since op doesn't even like the ROM...just flash to kk4 stock.
I would also make door that the phone is actually unlocked...but aosp doesn't have the same dialer codes to just dial and check, and i don't know those.

I agree that it is less invasive, but he already said he wanted to go to CM7 so I figured he could skip a step if the flash actually worked. He bought the phone this way so who knows what the previous owner did to it. Both ways should fix his issue though (unless his phone is locked, as you pointed out).
If you flash to the most recent nightly or a kang, the Samsung dialer codes work to check your lock status.

So, thank you guys for helping me, heres what I did:
A friend told me that since I had ICS on it, I had to flash a compatible modem on it, I flashed I9000BVJJPD which is used on cm9.
When it turned on, It asked for an unlock pin, I tried to generate it with the SGSunlock app but didnt worked, so I downgrade it to cm7 (2.3.7) and tried again but with no success...
Tomorrow morning Ill take it to an unlock shop so it can be unlocked (hopefully).
Does the modem that I flashed is the correct one for a network that uses 850 bands?
I heard that some captatives erased the imei causing the "unknown baseband" issue, I dialed *#06# and it retrieved the imei code so, it isnt ****ed right?
any help is welcome, Ill let you guys know how it goes.
thanks!

Up to you, which is the best modem out there?
No such thing..every phone acts differently, not to mention the signal at your location is a huge variable we can't factor in.

I know, but, for example, developers say that the lastest is the best, but, you only can say if you test them...
But, have you test some of them? Which gave you the best result?
I always include jk4 in my roms as a good standard.

I understand your dilemma. You look at a list of 50 modems and go, "Where do I even start?"
Personally, I have tried lots of different modems, old and new, and I always come back to KP1. I think it's worth adding to your list of modems to try out. I would also try JJJV5 and KG3.

I flashed the latest CM9 nightly two days ago, and everything seems to work great other than that I have no mobile signal. I am an Australian Optus user, and I tried it both with the modem that came with CM9 and with the one I believe is for my country, which is XXJQ3 by flashing that.
In both situations, I can scan for networks and see all three carriers just fine, but it shows no signal, just an "x" in the middle of the signal triangle, nor does it show which carrier it is connected to. I cannot make emergency calls because it says no mobile network is available.
Is this a modem baseband/firmware problem ? I am guessing not, because I would think that if it can physically see the networks, then the modem must be working right ? But if so, why can it not connect to anything ? The modem firmware I am using is for ICS and I believe it is the correcto one for my region, and I have enabled everything in the modem settings but still it will not connect to any network. Why ?

did you have try replace/update the modem radios from this? http://wiki.cyanogenmod.com/wiki/Samsung_Galaxy_Tab_(GSM):_Support_Downloads
you can try a different modem, It doesn’t matter if you prefer another modem, you can flash another modem, you can try flash any modem file you want, it's will not brick your tab
If you had, but still not working, then go to dialer, put this code *#*#4636#*#*, pick tablet information, try turn of the radio then turn on again and try to fix permission on cwm too.
good luck.

Thanks. Tried all your suggestions. Yes, that is where I obtained my XXJQ3 modem, which I flashed via CWM. I tried your other tip of turning the radio off and on again and then fixing permissions in CWM but to no avail. Still no mobile signal.
Is it correct to assume that if the device can scan for networks and see networks, then the modem is working ? The information screen you directed me to says "emergency calls only", but I cannot actually make an emergency call because it says "mobile network not available", so even though it can "see" three networks, it cannot connect to any of them to either get a signal or make emergency calls.
What does this mean ? Surely it has the right frequencies set otherwise it wouldn't see the networks at all, right ? Is this a CM9 bug in the nightly I flashed or something ? Wondering where to look. I get the feeling the modem is working fine and that something else is wrong.
I use the jlv modem from the vibrant phone.
But jpz modem is also OK for optus.
Why not do Android backup for safe keep, then restock using gb stock safe from overcome guide, and flash jpz modem to try.
If it is the same, then it is hardware related.

Oh my god. The reason it didn't work work is so stupid I had to headdesk when I realised. The SIM I was using was old and had been disabled. The reason I didn't think it mattered, is that in Gingerbread, it would still register and show reception bars and I could make emergency calls with the old SIM, or indeed even without a SIM in the device at all. But in ICS, none of that was the case, and it would not register and not let me make emergency calls without a valid SIM.
I guess I was just making a stupid assumption that SIM-less emergency calls that worked in GB would also work in ICS. Stupid me.
Everyone can make mistakes or forget something, but you should thank all the users who give you answers.

Hi!
Resume:
My note has some weird problem with the modems. I'm getting "Unknown" baseband, modem verison, phone number, IMEI etc. with all the modems I tried except one, which shows the correct IMEI and modem version but still not working(I can even see the mobile networks with that one, but I it doesn't connect and gives me "Refresing SIM data" messages).

I always have been using custom roms(only TW) and updating my note to the latest version and I never had a problem.
One day, some months after the last rom update, started to lose the phone network conection and I was getting pop-ups with "Refreshing SIM data"(was very annoying because that was turning on the phone screen every few minutes). Sometimes I had phone network and sometimes I hadn't. The disconnections became more frequently. The phone also started to eat up the free space for apps, so I had to remove several apps to install or update even a small one.
So I decided to change to a different ROM to see if that fixes both problems, but I got the actual problem.
I was in AllianceRom v3 JB when that happened.
I flashed this AryaMod 5.5 JB following their instructions and I got this weird problem. In the "About phone" says that the Baseband version, IMEI, IMEI SV, Network and My phone number are "Unknown". I can't even search for mobile networks because it says "Insert SIM card" when I try to open the Mobile networks menu. Tehre are no signal bars, only a "denied" icon on the status bar.
I tested all JB modems and some from ICS from the "all modems" thread, but I was getting the same "Unknown" things in each one, except the XXLSO, where the Baseband version, IMEI and IMEI SV were okey. I could also find mobile networks with this modem, and the "Refreshing SIM data" thing returned, but it was not possible to connect to a network. With this one, there aresignal bars, but they are empty.
I flashed the AllianceRom and even the old ICS rom I had before, but the problem persisted, even with the modems they came with.
Now I'm on the latest Samsung rom(LT4), unmodified and flashed with odin and the problem persist.
I found this old thread. His initial problem is very similar to mine, but they don't know what caused it nor how to fix it.
I have also found something about corruped IMEIs that you can fix doing something with the ADB and restoring EFS folder, but I think that is not my case because I can see my original IMEI with the XXLSO modem (and I my EFS folder looks OK, anyway I have no backup of that).
I don't expect to get a step-by-step tutorial about how to fix this, but I hope somebody can put me in the right direction. I will post the solution if I find one!

I tried both. Also I have been using the SIM with another phone for weeks and works fine. Tried to take out the battery and wait few minutes and other "stupid" things like re-flash a ROM, re-wipe all, etc..
Maybe it's the programed obsolescence, you can use the Note as PDA but if you want a phone, go and buy another...

If it was a corrupted IMEI issue then it should not come back when the xxlso modem is flashed.. And also not sure why it goes to unknown when any other modem is used.. Could there be any physical damage to the sim tray? Dropped the phone?
I have no backup of efs... I had one "nandroid" but deleted it after everything was okey...
I could delete the efs folder, so this unknown problem will turn a known one :victory:
I dropped the phone a very few times, maybe in one of those something broke a little and has increased more with the usage? (the disconnections from the network became spontaneus and progressively).
I found this other thread, I could try the same but I can't find the original GB firmware, every link I find is in hotfile.
Check in Samsung-updates.com firmware section. There are 2 GB roms there..
I found a efs backup from may 2012, probably auto-created when first installed ICS.
I flashed the stock GB rom and restored it following this tutorial for my .tar.gz file, but didn't work, so the device may be lost. I only have 3 more backups: boot.img, data.ext4.tar and system.ext4.tar. I guess they are useless to fix this...
Thay you for you support!
I just got the note 4, rooted it and flashed a rom, however I have no service it shows. I am using Metropcs and it shows "no service" no matter what I try, if I take the sim card out then it will show the logo that there is no sim card inserted so it does recognize it at least. The sim card and service works fine in my other phones but I can't figure out how to get it to work on here.

Are you still on TEKXodus? If you came from an older version ie..4.4.4 or whatever then I'd suggest Odin flashing 5.1.1 stock, see if you get service then try flashing the custom rom again. Might be a mismatch in baseband and all that. Open dialer and punch in these numbers *#12580*369#*and make sure everything matches. Also run thru the thread you found the rom and make sure you flashed everything suggested.

It is a T-Mobile brand phone, which I figured wouldn't matter much anyways, I've owned a few T-Mobile phones in the past and have had no issues using Metro Pcs even if the phone was locked because T-Mobile does own them. That's perfectly fine, thank you for giving some suggestions anyways that I hadn't thought of.
The Apn checks out? In settings?
U could also try flashing a data fix for the international roms. Maybe last resort try a new sim
Like the guy above said have you checked apn settings? You could also try in the mobile setting where it says Network Operators and then Search Now and let it search. Choose Tmobile if it pops up or if MetroPCS pops up choose that. If you need MetroPCS apns I have them since I'm on MetroPCS. Let me know if you've fixed this because I haven't rooted yet and plan to root and install Tekxodus rom but if this is a problem then I'll just stick with stock unroot. I have the N910T tmobile brand if that matters
APN settings have really nothing to do with his dilemma, my question would be this for the OP. Please check if the IMEI number matches the one that's on the back of the phone under the battery. I have a work around but i need to verify.
I went through the same problem coming from TekXodus rom. I tried everything and no luck. Flashed 5.1.1 stock and called tmobile about it. after their tech guy didnt know anything else i could try they sent me a replacement.
And now here I am again
I also flashed tekxodus from my wifes 4.4 phone. Now no sim card issue. Same as op.
Edit: flashed the correct baseband. All good over here.
