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.

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!

i think my captivate got an automatic update.
How do i know the nvdata.bin file has been deleted?
is there anyway to unlock if the nvdata.bin has been deleted ?
FYI I ran the market app from " DaGentooBoy" which also not able to find the unlock code. am I screwed ?
Why do you want to unlock?
Are you planning on switching to another GSM carrier or going overseas?
Are you planning on selling the phone on eBay and buying a different phone?
Or do you only want to unlock for the sake of saying you have an unlocked phone?
If you answered no, no, and yes (in that order) to any of those questions then you don't NEED to unlock.
Also, it was documented that upgrading to JH7 or JI6 deleted the nvdata.bin file from your phone, thus eliminating the possibilty of unlocking after you upgraded. You should have done it straight from JF6 when you got the phone, and backed up that file for future use. It pays to read and research.

this phone was giving to me by someone who left the country, and i'm on tmobile so i have no use for a att locked phone
boi.. i guess ur screwed then.. well there was a method to reset the unlock code to anything u want but u gotta search for it yourself in the forums here......dunno if that worked out for anyone....
also try searching the forums.....the nvdata.bin file i guess doesnt get deleted but the place where the unlock code is written gets filled with buffer values...
again, i guess i read somewhere there is a method to get past that but even that only worked out for some....
i could search the forums for ya, but im in office an cant do so now....
just keep on searching in the forums...ull surely find the solution....
also, this is what ive read only in some forums that people pay around $25 to get their cell phones unlocked by giving their IMEI number or sumthng of that sort......am not from the USA so really have no clue about it.....

Follow the One-Click Unlock guide

One way the unlock code could have gone missing is if the owner of the Captivate flashed to the leaked Froyo build and back to stock. As it is a leaked build it couldn't have been automatic afaik.
mine is a JH7 phone and i got the unlock code =D. at first i couldnt find it by the PC method. it wouldnt work. it gave me an error sagint the nv_file.bin wasnt there. and i searched for it and it wasnt. i thought i was screwed so factory reset,then i rooted my phone, enable sideloading using unleash the beast. After all that, i went to android market and search for "froyo" and supprisingly i found a unlocker that worked. (looks like a padlock perhaps 5th in the list) i installed it and ran it, IT FOUND IT!!! was so happy since im not even in USA and i can use it on any provider =D

I don't think it will get a signal on Tmo's 3G system, so why would you want to use it on Tmo's edge anyways?

You are correct. T-Mo's 3G frequency is different from AT&T's. T-Mo uses the 1700/2100Mhz range for their 3G while AT&T uses the 850/1900Mhz range. The only frequency range the companies share is the 900Mhz band which is 2G

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.

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.
i bought the galaxy s off ebay of the guy claiming it too be unlocked to att well when i got it wasn't i tried everything galaxy windows unlock generate galaxy s unlock app EVERYTHING!!!!!! and nothing works ive seen multiple ways tried em too still cant get it too be unlocked.im using firmware jpy and im using darkys 8.0 rom
Google up "super oneclick" and see if that will get you the unlock code.
Have you gotten unlock codes from any of the other attempts?
What happens if you use them?
Do you get any kind of connection at all? Voice calls only?
Dump Darkys put stock Eclair on and see how the phone behaves .

Try this, It unlocked my phone where the oneclick option had failed.

im going to try to try these methods
I bought SGS from 2nd hand for my girlfriend. Seller said that phone is locked for Virgin (UK). I successfully removed simlock from my SGS (O2) before so i thougt that shouldn't be a problem for me now. But it is.
I checked with *#7465625# that simlock and all other locks are OFF (before i used phone with SIM). When I put any other SIMs than Virgin I get "Emergency calls only" message. Virgin SIM cards work perfect.
I tried remove lock (but there is no lock ???) with all methods from this forum and still have no reception with non Virgin SIM. I checkd 2.1, 2.2.1, and 2.3.4 stock roms and is same.
How I can resolve my problem?
Its possible if u have been using Odin that you have changed the CSC file, which is the modem, which receives signal. Does Virgin receive a signal ?
Yes, Virgin recive signal. Problem was before I flash any rom by odin.
I can see signal bars when non virgin but can't make call. Only emergency.
Maybe I can use some files from my unlocked and working mobile?
Ok, go here http://www.samfirmware.com/apps/profile/76570387/
You will need to register free, and you will loose root but thats easy sorted, download the latest 2.2 for the i9000 and flash it with Odin. Let me know if it helps, and be carefull with Odin, read all instructions carefully. Though i think the 2.2 is just one file, there for it goes into PDA in Odin.
You may also be sim-locked again, im unsure and im no expert at this. Or theres another site that helped me out. http://www.theandroidsoul.com/xxjvp-android-2-3-4-firmware-galaxy-s-install-and-download/
Then go here to root http://www.theandroidsoul.com/root-xxjvp-firmware/
Let me know how u get on

I try to use few firmwares but it not change anything. I think that might be problem with nv_data.bin file. In my opinion someone try remove lock, failed, forgot to backup file and sold mobile to 2nd hand shop.
I have another full working sgs. Maybe I can copy some files and/or edit in hex editor?
Edit
Maybe someone can share me his nv_data.bin from locked or unlocked Virgin mobile please?
Sorry about link, but thats the site for the official firmwares from Samsung. I cant help you with copying files man, I know nothing about it.
