No cell radio.(Mobile Network Not Avaliable)

So I finally got my Captivate rooted and started flashing roms to it.
I've tried CM10 and CM9 and neither had radio. (I'm running Helly Bean right now, and still no radio)
I've tried flashing modems to it and still nothing. I tired most of the ones on the modem dance site (cant link to it yet)
So some info about the phone.
Android Version 4.1.1
Baseband Version: Unknown
Kernel VersionL Devil 3.1.1.7 Cappy
CyanogenMod Version: Helly Bean Cappy
Build Number: cm_captivatemtd-userdebug4.1.1JRO03L
So how can I get cell radio working again?

In the settings menu, does it show your IMEI? (Do not post it if it does, just look for it.) If it shows "unknown", your /efs folder is goofed up and you'll have to try to fix it.

You are flashing ics modems right?

When you say you tried flashing several modems did they flash correctly or did you get an error when you attempted?

It doesn't show anything.
I read about copying the /efs folder from the backup, so i tried doing that (which was a chore, since I couldn't figure out how to mount "/" to get to where /efs needed to be, ended up doing it from the filemanager in the recovery. But that didn't do anything.

No error, the recovery always said the install was successful.

There's a thread about restoring your EFS folder from the phone in the development section. Give that a try. If that doesn't work, there's also a program on XDA called "EFS Pro" that might help you out.
I've also found that flashing Mosaic 9 after flashing back to stock will fix it for me (don't know why, though...).

Thanks, I'll make sure to give that a try.

Don't touch efs without going to stock first. When a modem isn't flashed during the initial repartition install, this sort of stuff happens. It should be normal on stock.

I must have been looking at something else, because I do not have an IMEI number.

what about IMEI:
*#06#

my imei still matches whats printed under the battery so thats all good.. has to be baseband doesnt it? in get RIL (from market) it states my baseband is the 18a EUR baseband but the RIL does not match. Im going to try and flash either the 21a baseband or the 21e (if i can find them)

is there anyway to flash basebands from CWM or does it have to be done via flashtools?

Could my lack of signal be anything other than baseband?

can i just say
**** me, i decided to have a game on my phone (since the wifi works and i wantted to shoot some people cos of the hastle... and as i was playing i got a text, now i didnt think anything of it. i just thought ahh for ****s sake, always when im playing on this someone texts me...hang on... someone just TEXT me. and low and behold my signal has appeared! WOHOOOOOOOOO i have a phone again!
not sure if i have 3g/H though as my phone just states a solid G with no up and down arrows but that could just be my location

Still an issue.. lock screen says (no service) and i have no mobile data. Must be baseband surely

well.. im off home in 10 mins, hopefully ill have a fully functioning phone not long after that.. then, dare i try the ICS again.:silly: i mean it worked fine last time, i flashed the bin then the fls ( i think that was the order) and it took a little while to reboot but ultimately worked. it was me arsing around with fastboot that killed it.

920 & 925 .dll

I never really paid any attention to it but I lost all my files when I formated my computer last night; is there any difference between flashing with the LGP920.dll or the LGP925.dll file when flashing? Just not gonna hunt down a P925 if they do the exact same thing.
Sent from my LG-P925 using xda premium

Big difference. In fact each of the DLL contains modem sign-in keys for to allow the modem firmware (CP) update. However Android OS (AP) image doesn't matter for those keys - whichever just simply serves to provide the partition information. But, KDZ already contain the DLL inside anyhow. So if you are updating the baseband, use the DLL as indicated by the model ID on IMEI / FCC ID sticker under battery. Even the tool won't update the modem baseband with KDZ containing wrong DLL. I found out the hard way.
Sent from my LG-P920 using XDA

Thanks man That makes since. Well I wonder what's been going on in my phone because I have never had luck flashing kdz's. I had gotten ahold of a shttp (cant remember exact name. It was the lil file that blocks LG servers) that decimated my network; thus why I formatted my cpu last night. Anyways I use LGExtract to turn Kdzs into bin and fls files. I literally just flashed P925_V30B_00_CP.flsbase and with LGP920_11062.dll......Reason being cause I flashed back my bigpartion 28B. It didn't block me so any clue of there being something wrong that I can't see?
Sent from my LG-P925 using xda premium

Well, if that works, that's fine but CyanogenMod is rather fussy; it can actually read the modem firmware ID, as you can see in the attached picture - I had to flash V21D baseband into my phone so I can have Internet on CM10 ROM. You can check it out with Getril - if unsure, you can take screenshot (power + home or power + volume down - the snapshot's in /pictures/screenshots but save the picture as JPEG first so you can post it here).
Also, about LG flash tool, if you used wrong DLL, the utility will simply hang, whichever it just refuse to flash the updated baseband firmware.
Sent from my LG-P920 using XDA

Yeah I just use flash tool 1.1 it flashes base and to 27% on ics basebands and then of course fails but says download success
Sent from my LG-P925 using xda premium

25-27% is enough to guarantee successful modem firmware update. The reason the LG flash tool failed is because it was looking for Android image AP bin, just disregard this one. I have done the same thing - just CP fls file. V30B - that's a successful flash, as you flashed V30B baseband.
Sent from my LG-P920 using XDA

Cool I thought so but thanks for the re assurance :thumbup: I still find it odd myself that i unpackaged the wdb file with a p925 .dll bit turned around and flashed it with a p920. I honestly thought it would throw me a warning at me. Oh well thanks mate.

There a thing i don't understand i wanted to flash p920 v30a ics downloaded from lg server and having only kdz i've extracted it with lg extract to flash with lg flashtool and so i wanted use the LGP920.dll extracted from it since seems to be more recent (version 1.0.0.5) but when i have opened it in lg flashtool it says SU660 dll and i couldn't start flash. Why this while it come from the true p920 rom?? it's strange, isn't it?

Well, I tried flashing P920 KDZ onto my LG Thrill 4G - of course, it installed just fine BUT the modem firmware remained the same all through the entire episodes only to be eventually noticed in CM10 - it wasn't flashed with P920 modem firmware but rather the same Froyo baseband, P925-V10B. It was eventually traced back to the type of DLL used due to modem sign-in keys.
So try the DLL specifically made for the phone and then flash the extracted AP and CP binary files with LG Flash tool, it will work this time.
P.S. Be careful - only three models of firmware is supported via any of those phones; P920, P925 and SU760. And if the KDZ is for P920, replace the SU660 DLL with P92x DLL. I have come across that mysterious DLL once.

you have to set the IMEI search it

You have to find out how to talk to the modem via terminal - there's guide here on this forum, aimed for IMEI recovery.
BTW, I am not surprised that if another SIM doesn't work, and original one work in different phone - your modem firmware's messed up. So you have to write in the IMEI numbers, or just flash in new baseband firmware (probably write new IMEI afterwards).

go back to v21e

[Q] IMEI and Baseband unknown, doesn't recognize any sim card SGS4G

Hello guys, couple days ago I bought a SGS4G, the T-Mobile one, not sure if there's another versino anyways the model is SGH-T959V.
When i turned on the phone everything was alright, but it wasn't recognizing my sim card, so i thought it wasn't unlocked, but that wasn't the problem.
I checked the settings and the phone info and i saw baseband unknown, imei unknown, everything! so i did a factory reset, flashed to stock, got 2.3.6 rom on it. Nothing worked only thing that appears now is the MAC address, can someone please help me!? I'm really desperate and I need to use that phone, really need to use it!

hi. don't sure how i fix this everytime i had this issue but a few days ago i encountered it again. took me some hours, done flashing to stock to restoring and so forth but still it was no good, still no signal because of unknown imei and baseband. then i re-read some things about this issue. finally it lighted up my mind and solved this.
http://forum.xda-developers.com/showthread.php?t=1480418 - The Definitive Noobs Guide to Flashing and/or Fixing the SGS4G! POST QUESTIONS HERE! by Juls317 said that Modem ([Mo]dulator [Dem]odulator) -> helps your phone interpret wireless signals sent from your cell network and wireless routers and also send data back to them (flashing different modems can help improve your cell reception) (thanks FB) . once i re-read this , i assumed that this is what i need to bring back my lost imei. (credits to him)
tried flashing a modem of galaxy s 4g and boom! the signal,imei and baseband of my phone came back.
so here's what I did:
I flashed a stock rom of galaxy s 4g. froyo or gb, doesn't matter which two. (via odin) check the pda then reboot
next, I flashed again via odin a bootloader with cwm. (check the bootloader and let it reboot)
then, flashed again via odin a modem of galaxy s 4g (i used kj6 cause i remember mine is kj6) check the phone then reboot
http://forum.xda-developers.com/showthread.php?t=1192436 - here's the link of modems by fbis251 (credits to him also)
the reason i flashed a bootloader with cwm is that i have a zip of sgs4g rom in my sd card which i'm using currently.
then i reboot into cwm and flashed my saved rom in sd card via install zip from sd card.
after that, i restored my backup in cwm and there my phone is, still good as my last backup.
i'm not familiar with using the adb terminal emulator so i don't know about those things they said about the efs folder in renaming the .bin files to recover the imei. sorry for not giving the whole step-by-step flashing things but i'm sure you'll understand some things i said especially those who uses Odin. hope this helps!good luck!
