Are you sure you didn't do anything else? People usually get this problem when they try to unlock the phone with market applications. Search for Imei in the forum, there are a couple of fixes:

install another modem

I odin'd
The phone was purchased used, but I did not try to unlock it, and have been using it for two weeks. It was not even rooted.
I went into download mode, and Odin'd to the KB firmware. Still searching, and null/null imei if I dial the code. But maybe a modem was not included. I will install cwm and flash a modem.
Thanks,

installed another modem through cwm fake flash... no dice... same issue.

fake flash?
anyway, try one of those links i posted before...they are all fixes addressing your problem....

need help, flashed miui lost data

Hey guys I am in a bit of a bind. I flashed miui with cwm and now it says roaming. I went to another tw Rom still roaming... I tried the imie tool says it's fine!! Double checked with the sticker under battery. I been trying to dl a stock Rom but it's file server is way to slow I can't stay in WiFi for 5 hours wifey is upset. I have her phone it's stock but I can't find a way to back it up without rooting it?
First question, what did the Rom do to my phone?
Second question, how do I fix it?
Thanks for reading this I hope you guys can help a n00b
P.S I was going to flash the stock Rom with Odin I have that setup but no Rom. Ideas?

Your ERI might be wrong and say you're roaming when you're not. I thought that tool had an ERI fixer also. If it doesn't, try this:
Back up everything you want that is on your internal storage, put it on an external SD or your computer. Then dial *2767*3855# on stock touchwiz. It will wipe your phone and reprovision it. Should fix the roaming issue.

It reprovisioned your phone and you're still roaming?

Try running the ERI repair tool in the linked thread. You need to be running the LF2 modem. If you arent, you can download it from the second link. You can flash .zip modems in recovery, or .md5 modems in Odin.

[Q] [Help] Skyrocket go down!

hi everyone. I need some help here with my At&t Samsung Galaxy S2 Skyrocket. I had my phone unlocked and work on T-mobile GSM fine but I only got EDGE for data. I then flash it with with a T-mobile radio according to the instruction here at XDA forrum to try to get 3G/4G. after flashing the radio the baseband in the phone showed "unknown" and I lost both GSM and EDGE. the phone even didn't recognize my SIM card,I don't know If I did something wrong.
Here How I did
1. I flash CWM 5.8.x
2 I update to CWM 14.x.x touch version
3. Root the phone with SuperSU busy box
4. Flashing tmo_SGH-T989_VK1.zip radio
5. No signal.
It seem to be the radio I tried to flash didn't go in correctly. BTW I still keep the stock ROM form At&T (ICS 4.0.4)
Any one have experienced the same problem like me ?
Thank you very much for helping me out.

Just so I'm clear, you flashed a T-Mobile Only Radio on an A T&T Sim card? Check your APN too.

I flashed T-mobile radio on AT&T phone not SIM card. I lost my original AT&T Radio and new T-mobile radio didn't go in, now the phone doesn't read my T-mobile SIM card. I cannot access mobile network to check APNs without a valid SIM card since the phone doesn't see it.

the phone function was perfectly fine before I flash the radio. of course, no 3G/4G connection on T-mobile

the problem is after flashing custom radio, I have no radio at all. the phone is now a tablet

Did u make a backup? Did u try flashing a new radio? Try odin mabie and go back to stock and try again.

thank you for you suggestion.
I finally understand the problem the phone simply doesn't accept the radio. I flashed the new radio and turn out the original radio was removed and new one didn't go in. when i flashed a full stock ROM the original radio came back. may be the ROM and radio have to be compiled together.

Uh no you have to flash the modem before the ROM to get a good flash from what I've seen. Also I think almost every radio exempting maybe gingerbread radios as I haven't tested them should work on every ROM exempting maybe tw based.

The Rom or radio can be flashed in any sequence. The order they are flashed in has no effect.

Did you flash the radio two or three times in a row?

Fixed that for you. You forgot to mention that you have to hold your breath while you wipe dalvik 3 times, cache 6 times, factory reset 2 times, perform a backup and then flash a kernel from a different device.

I agree. Flash baseband - if for CyanogenMod, flash V12D/E or V28/30.

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).

[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!
