Did you flash it back to stock with the one click Odin or did you Flash Jf6 manually?
Try the one click Odin ROM.

Yeah, try flashing back to stock with Odin One-click.
Also, is your SIM card in correctly? I know, I know, but I have seen that happen, it's worth checking out.

If you tried flashing the latest I9000 froyo build try and contact Zilch. He had the same issue. But he figured it out

i think i broke my phone :( help needed

hi all
i thought i would attempt to flash my samsung s with the new beta froyo update.
i followed this guys tutorial.
( cant link to it sorry its the noobs guide with detailed instructions through kies and odin)
i used the odin approach
i managed to root the phone.
on reboot it asked for an unlock code (o2 uk) so i went on to try and follow the steps about unlocking it. which neither worked all the way through the steps.
on reboot it appears to have signal and in the about section it says i am onnected to the o2 network but when i try to make a call is says "data network not available with an ok button, which when pressed will return you to the ome screen.
any help would be greatly appreciated thanks

Almost the same problem,
installed 2.2 update successfully, the phone worked for like 3-4 days very well and after that today i discovered "Emergency calls only"
so the question now is did i bought phone which later was reported stolen? or somehow i broke it?
Anyone have any idea?

hmmm, I have the same problem! In the status menu, the number is shown, but the network, says "unknown"

Hi! I have this exact same problem except I was unlocking my phone using this tutorial:
http://forum.xda-developers.com/showthread.php?t=906255
But I didn't back up my Efs folder, now my phone is unlocked but when I put a sim card in it I have very little network and when I try to make a call I get " NO DATA NETWORK AVAILABLE".
I've tried everything but I don't know what to do!
I was thinking of two ways to fix it:
1. Reinstall froyo (not quite sure how using the samsung software as my laptop oesn't recognised the phone as a pone)
2. Downgrade to, get unlock code using market app and then upgrade to froyo again.
I know I messed up but now I really need to fix this.
Can someone PLEASE PLEASE help me out.

might need to change the modem in odin i think. just heard about it

did u try restarting the phone... just a wild guess...

I had the same issue before and was puzzled. Its actually a very simple solution:
1. Re-lock your phone, search through xda there is a code you have to enter
2. Unlock your phone
All done! Surprisingly easy

Try the Odin method in block 2 back to Eclair if ok then upgrade to Froyo .

However your non connection might be due to not flashing a firmware with your network settings in which case manual settings of APN .
If your IMEI has changed due to flashing and you did not back up your EFS folder then little hope but do a google / search of XDA as some have reported success .

Emergency calls only
I had a custom rom that was giving that to me too. I think it means that you can access a network different from your sim (because usually emerg calls can be made from any phone I think?).
I'd try and find a rom that is optimized for your carrier or at least a modem file from a stock rom that is for your carrier. You may also need to reselect the APN settings (or enter them for your carrier). Its under settings/wireless and network/Mobile networks/access point names (use the menu button to add an APN).
you could also try re downloading and flashing the rom to make sure that is the issue. Mine said it installed OK but never booted up, redownloaded and reflashed and then it was fine but the install screens looked identical.

Hi! Thank you so much for everyone's replies!
My IMEI isn't changed and someone helped me check my efs files and they are all ok. I'm going to try and reflash froyo through the samsung software to see if the network lock comes back and then try to unlock again. For this I'm going to unroot the phone and follow samsungs' instructions.
I'm afraid to relock the phone as there are reports that say it completely messes everything up!
But I'll keep you guys posted! Wish me luck!!!!
PS. Any other suggestions are more than welcome!

So, a quick update on my situation.
I uninstalled busybox and unrooted my phone using the oneclick root tool.
Did a factory format and, surprise surprise, my phone now works perfectly!
Apart from the fact that it doesn't connect to kies, but that's a whole another issue!
Tank you so much to all of you who answered my cry for help!

[Q] No SIM card in phone

OK guys... I usually lurk, but find myself now needing help.
In an attempt to help my friend, I was going to root his phone and install a custom ROM. The phone is a 1010 build and I forgot to remove the SIM when performing one-click-root.
Now the phone will not recognize the SIM card. I don't think the SIM is bad because it won't recognize mine either and my card works in my phone.
I followed the instructions for 1010 builds back to JH2 and the SIM is still not recognized. The phone came with JH7 installed, but I figured that the SIM would be recognized after booting into JH2.
Can anyone offer assistance?
Thanks.
EDIT: His SIM works in my phone. Just thought you might ask.

Bump please

I had this happen in my old Tilt lol. Try backing up the sim from your phone and if not, you have to get a new sim.

The SIM card still works... just not in this phone. It works in my captivate. I think I am in trouble here. <slaps self> That's what I get for rooting company phones. :\
If anyone knows something that I can try to get this phone to recognize the SIM... please chime in. Right now I am back to JH7 rooted.

verify that you have the right modem in it and check the APN settings

Model Number: SAMSUNG-SGH-I897
Firmware version: 2.1-update1
Baseband version: I897UCJH7
Kernel version: 2.6.29 [email protected] #2
How do I check the APN settings?

Sorry... can't verify APN settings if SIM is not detected. Looks like I'm hosed. Thanks for the replies.

APN shouldn't affect recognizing the SIM. Are other SIMs working with this phone? You may want to try either a master clear, or downloading the ODIN version of 2.2 stock to see whether they will recognize SIMs before returning the phone.

Try a rom! Or kb1 or ji6 try flashing like everything to it, hopefully that'll do something also go to settings>privacy>factory data reset and make sue you backup first

Yes i know. My sim card still worked in my captivate just not my tilt, all you need to do is go to at&t and tell them your sim card isnt working. They should be able to transfer your contact and get you a new one. But this just a last resort, try these guys suggestions

You can get apn settings by pitying your friends sim in your phone
Sent from my SAMSUNG-SGH-I897 using XDA App

even new apn settings wont load if its not detecting the old sim. i ran into this but didnt fix it. got replaced. different situation....
i had this after a noobish bad flash where i odin'd to phone instead of pda.
i lied my ass off and got the phone replaced that night, as i NEEDED the phone THAT NIGHT no time to play and fix myself. that was by bad! now i flash at night only when i wont need my phone for hours.
you dont need to take out your sim to root. i never have. i use oneclickroot 1.7.
so im not sure what you did to screw it up.
but if someone elses SIM works in your phone then that means the phone is fine. AND if your SIM doesnt work then it means your SIM doesnt work!

[Q] Flashed wrong baseband

I have a CDMA Milestone on a small local carrier (Bluegrass Cellular), and flashed the C 1.43 baseband (stupid mistake!). My carrier uses the C1.07. I found the .SBF file and flashed it using RSD Lite. I now have the correct baseband and 2.1 Android installed, but apparently the settings for the EVDO are wrong. Is there any way to find and change these settings? I took it to see if Bluegrass Cellular could do anything with it and they seem to know less than I do. I told them that it had previously been rooted, and they just assume that's what caused the problem. The phone, texting, and everything else works fine-just not the mobile network. I hope I haven't made a $300 mistake! Any ideas?

I'm in the same boat so if anyone has a solution or a stock Bluegrass sbf it would be much appreciated.

I'm with bluegrass also and am trying to avoid this very dilemma. Did it mess yours up when you flashed a ROM or how?
Sent from my A854 using XDA App

Try flashing another rom, another version ?
Since phones now have USB, i don`t think u can brick it...
And since nobody got a solution, u should keep trying til u find a solution or someone post it here ;D

Baseband version unknown, IMEI unknown after flashing Helly Bean

I went to stock GB from an ICS ROM, and then to Helly Bean. Everything seems to work fine except any kind of networking. I cannot connect to 3G or AT&T's stuff (text messages, calls, etc.). I can connect to my wifi network and use it. In the Settings on my phone, Baseband Version and IMEI are unknown. The only thing in my efs folder in Lost and Found. I have no backups, as I wasn't aware that this problem existed.
Not sure what to do. Right now I'm leaving the SIM card and battery out for a few minutes, and then putting them back in to see if that helps. I'll probably flash a modem as well. Any suggestions? Any known fixes?
edit: Tried the battery removal and modem flashing, neither worked. Now going back to stock.
Edit2: going back to stock did nothing. I tried another SIM card, and that one also does not work.

I went back to stock GB again (third time now) and it's now recognizing my IMEI, but I still can't text or call.

Check your APN. And don't forget to backup that efs folder...just in case.
Sent from my SAMSUNG-SGH-I777 using xda premium

It's not letting me look at the APN settings because it still doesn't detect a SIM card, only my IMEI.

Anything under Baseband ?? If not try flashin a modem through Odin.

Okay, I was definitely having a legitimate problem earlier, before I flashed to stock. At some point in this repair process, my SIM card ended up in my phone upside-down.... woops.
Thanks for trying to help me 4-2ndtwin.

Ooops...sh** happens lol.
Glad u got it fixed !

This thread most likely has to answer.
Check your APNs to make sure they match your carrier's.
Check your IMEI to make sure it matches the one with your phone. If it's not the case, you'll need to go back to stock KK4, backup your efs folder with a app that has root rights (like ES File Explorer) and restart the falshing process.
A good backup would be suggested before going to stock!

same problem baseband is unknown and imei is null. help
