I just flashed my SGS to JM8 through KIES from JF5.
It was very strange. The first few times it kept giving an error that got me sweating and said I needed to restore my FW. Still, nothing happened, there was no option to do it.
After the last time it did I told myself, "Last time trying and then go to ODIN!".
When I pressed update again the phone said "Can't update, need to restore ROM". So I did. After restoring my ROM was JM8 and all my data was still on the phone!
I was really happy, given that I've read that all my settings and data would be cleaned out!
Still, now comes the problem! I wanted to release the NETLOCK from my SGS and the software asks me if I have an SNS and doesn't give me any codes!!!
How can I get my codes now??
Thanks for your help!
Have you already tried to restore your bachup of /efs?
My Help was to delete the nav Files then reboot and my IMEI was back again..
The most recent firmwares just erase the unlock codes from nv_data.bin and from nv_data.bak.. You should have unlocked it before the upgrade.. Now the codes aren't on the phone anymore, so, there is no known method of obtain the codes from you phone.
Now the only way is to purchase the codes, from TMN (or not)...
Hi there, I have the same problem....
JM8 firmware and unlock applications not working.
I bought a code from cellunlocker.net but it doesnt work and now I am waiting for their assistance (another code?)
Do you now a site which we can buy a working code for unlocking a jm8 from TMN? But one that works....
help!

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 .
http://forum.xda-developers.com/showthread.php?t=818556
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!

Hi there! I'm from Argentina.
I had a problem a week ago, when I tried to root my Motorola Milestone.
When I updated the SBF and applied an update.zip (just to avoid the OTA 2.2 update problem) my IMEI went blank.
I did't even root it yet. The problem is that I have the "NO SERVICE" legend.
Tried flashing some Argentinian (and other countries) Radios but nothing happened.
Then, when I press *#06# no IMEI shows on screen, just a box to press OK.
My IMEI was: 356698030155635
And my carrier is: PERSONAL (AKA: UNIFON Argentina).
My phone it's not on warranty period, and technical services here don't know how to solve my problem.
Is there any way to put back my IMEI? If not... What can I do or what can I try?
I can't use my phone
I'ld try anything available... can't get any worst.
Anyone had the same problem?
Thnx in advance for your help!
PS: Sorry for my English.
--- UPDATE:
Well... Just made the update process from stock all over again, like 3 times. Now IMEI reading is correct.
I don't know why it got cleared, but now works for me...
Thnx anyway! I Love this forums.
I flashed my phone to a pre-release FROYO .. and now can not unlock it ..
I have tried using an unlock service to no avail .. and received an email from them saying this :
"""However if you indeed flashed your phone to JPC version with non released firmware (reg hack via KIES) it is possible you damaged your NVM data and phone will NOT accept the unlock codes However if you indeed flashed your phone to JPC version with non released firmware (reg hack via KIES) it is possible you damaged your NVM data and phone will NOT accept the unlock codes "
Does this mean I have ruined something in my phone and now I will NEVER be able to unlock it? ..
Thanks
Try the search next time.....
For now, see this thread - this technique works for 2.1 and 2.2 but it depends on your phone having a good EMEI.

So is it locked for good? Unknown, as you didnt mention what you did to it.
Took me a long time. I had the same problem, it worked for me. The instructions werent perfect but I manged to get through them after sometime. Hope it works for u
I have a newer I9000M on JH2 from November and I haven't yet found a way to unlock it that works. Every single strategy I've found on this forum is a dead end. While my handset from September unlocked easily, every newer version I've had cannot be unlocked.
I've upgraded to JK4, downgraded to JH2, tried JPO, gone back to JH2, but nothing works.
It is my belief that everyone with a newer Bell handset is also finding it impossible to unlock. So rather than have us all waste time trying to find a solution that doesn't exist. Let's just admit it:
It doesn't exist.
Right or wrong?
UPDATE:
There is a solution (thanks to the ingenious Happy Hunter) but its not easy and not for noobs: http://forum.xda-developers.com/show...postcount=1202. You can't unlock the I9000M to use on any provider, but you can "change" the lock from Bell to your provider.
It failed for me numerous times until I rebooted my computer and followed the directions literally step-by-step. If you deviate slightly from his method (i.e. use z4root instead of SuperOneClick, or type the wrong text), you will fail.
Still waiting for a universal unlock or automated solution, but am satisfied with this for the time being!

i got a new motherboard after it got back from repaired can back w firmware JK4, and there is no way you can unlock it, the only way to do it is use hex editor and edit the nv_data.bin file to locked to a network your sim card is on, thats the only solution right now.
Try this...

You must have an older Bell SGS. The app doesn't work for phones with a newer manufacturing date.
I noticed after I relocked mine that's I couldn't unlock it again. One of the threads noted you can use the unlock code to lock to a different network as needed.
UPDATE:

Yeah, I just got my phone back last night after being repaired - I tried to use the app (for some reason my Bell prepaid with $0 on it was able to access data for free), I got the unlock code, but it said something along the lines of "Network authentication error" when I tried to do it.

Anymore info on this procedure?
Edit: You don't have to use a hex editor, but it seems re-locking your phone to another network is the only way.

I did the "no-sim" method and it worked enough that I'm back on rogers.
sadly I dont have backup of the files before flashing
I can access data, but I cannot make\ receive phone calls or messages.
please help as this is my only phone?
not sure if I can revert to an older rom, and which one to pick up.
I got mine on orange UK.
Are you saying that you don't know your IMEI?
1. check your invoice when you ordered the device (mine stated my IMEI).
2. login to orange uk website to manage your account and surf around, my IMEI was also listed in there
Or that you don't know how to change it?
1. What ROM are you running?
2. There is a secret code you can type into your dialer which will simultaneously do a factory reset and change your IMEI. Search the forums for this.
I remember reading somewhere on here that if you flash back to FroYo it will reinstate your IMEI number.
Perhaps use JPU 2.2.1
Hope it helps ;-)
flash with odin and done
