I'll go ahead and get a couple things out of the way that other people will probably tell you about with varying levels of aggravation (don't shoot the messenger, I couldn't care less):
This is a question. It goes in Q & A. The development forum is for development.
Odin is a dangerous tool, and you have to be careful with it.
If your MEID number is still valid in Settings -> About Phone -> Status -> MEID, then you are probably ok.
You may be able to *228, option 1. If that doesn't do it, try *22899.
If that doesn't work, activate an old phone on your account, then after a few minutes, reactivate your Samsung Fascinate. This will hopefully restore any of the EFS data that wasn't getting pushed by the *228 activation.
If your MEID in the Settings menu doesn't match the one printed on your phone under the battery, then the EFS data was corrupted and unable to rebuild after you cleared it. The only realistic option at that point is having it sent to Samsung.
thanks gizmo
question were u able to fix it i haven't done it i am always intrigued by stupid mistakes lol jk

Well, he deleted the OP that made it a little clearer... He actually cleared the EFS.
The phone section in ODIN is just a specialized field for flashing a radio file (PDA is like an all purpose). At least, this is what I gather from other's experiences. (Fully admitting that I have a bad memory).
But the "Phone EFS Clear" checkmark is for clearing the efs partition so that it will rebuild the files that contain your MEID number. It also clears the information that is pushed to your phone during activation.
Given that everything was set up properly, he should be ok after activating again... but that's not always the case. If you clear the EFS data and the files that repopulate the data with your MEID are corrupted, then there is no way to regenerate that info without shipping your phone to Samsung.
Given that no one much talks about the EFS partition on the Fascinate, I've only learned this info from the other Galaxy S variants, where backing up the EFS is a major first step before changing anything.
There is a small possibility that these principles don't apply to the SF, but I'm thinking that until someone proves otherwise, it's better safe then sorry.
OP el-solve-ed his problem. Thread closed.

Is your IMEI correct ?
If not you have a corrupt efs folder

You can't simply "get" an IMEI. You need a backup to restore it.
Another way would be if the encryption algorithm becomes public, so you could simply restore your old IMEI by rebuilding the appropriate files.
From what I know the algorithm is still unknown and as such you will have to rely on a backup, speak with the guy who sold you the phone.
Btw:
Samsung could restore it, too, they can simply rebuild the files (aka encrypt them properly).
About the backup part, this thread might help:

Hello, today I got a live demo unit from Samsung, but it's a small problem, in this device, it is not possible to use the phone part, it is possible to fix this? phone is not locked, and the sim card is in working, and all apn is i order, but it wont register on the network.
NEW INFO!
My phone is "out of service" and i cant turn it on, so i can use it.. can some one please help me.
the raido is working, becasue WIfi is working, the same with thew bluetooth, so it seems to be loocked for use of sim cards.
please help me some one?
my imei is a very strange imei starts with 00499................
Hello Jespersen84. Seems like i9300 live demo units don't have their own IMEI (they all have the same) and the EFS folder isn't complete, some files are missing.
You can use everything, except phone calls, sms, mms and 3G data.
Thats correct,
but i was hoping it can be fixed, maybe change imei, or is it possible to copy the files that are missing to the efs folder?
i have tried to root it, i have installed new custom rom, nothing wil work, i thing i have to cange the IMEI to get it to work.

Change IMEI is illegal and against XDA rules .

Closed, as changing, and discussion changing IMEIs is illegal, and against XDA rules.
Hi guys,
After dumping the NV data of the i9305 with QPST, i wanted to make sure that i had a valid backup. Like the pessimist i am i took 3 backups to be safe.
I opened a backup in a hex editor and found item 550 (IMEI) changed a value up one digit and re flashed the modified QPST file back to the phone, all went well and the phone rebooted. Dialed *#06# and the change i had made had not "stuck".
Now im concerned that if i do run into any issues down the line i wont be able to fully write back my backup...
Looking around the web it seems the i9305 does store imei and other data elsewhere on the phone, im guessing the modem but have not seem anyone specifically say.
Can anyone shed some light on this please, ive seen some scary stories about null imei's and invalid imeis generated during the use of custom roms and dont want to be banging my head off the wall if faced with these issues myself.
Thanks
You want the I9305 Q&A forum and I9305 Development forum .

Hello, a few days ago I dropped my Samsung Galaxy S II in a small bucket of water. I immediately took it out, pulled battery out. Waited for it to dry up (used hair dryer) pulled battery in and ... well it worked ... sort of. Everything worked apart from WiFi and USB connection (i.e. PC does not recognize mobile) which is not that important, most important was that I could phone.
I did make phone calls and I did receive phone calls. Then I changed the simcard with another one (I was abroad when the accident happened so abroad I use one simcard and at home I use another one) ... and I got no service. I put back the previous simcard and still no service (note: both simcards work in other mobiles).
Then I realized that pressing *#06# I get just a message box with 'IMEI' written but no IMEI number (not even a default one, none). From the mobile settings (Settings > About phone > Status) I can notice that IMEI is unknown and IMEI SV is unknown, Baseband version is unknown as well.
I tried factory restart (a few times now)
I searched on the internet. Installed Framaroot to root mobile (as mobile was never rooted), installed Root Explorer and Terminal and followed a tutorial that basically asked to make a copy of EFS folder, delete original EFS folder, reboot, copy .nv_data.bak in the root EFS folder (from the copy), rename this to nv_data.bin, copy imei folder, etc.
This did not work.
I also tried to BusyBox and GSII_Repair but GSII_Repair does not manage to repair either (i think because at this stage by EFS folder is already doomed).
What I noticed is that in my "imei" folder in the "efs" folder I only have three files and none of the files have an imei number.
So my question is: does anyone know where the imei number is stored?
or if there is an app that simulates an imei number?
Mobile looks ok (I can literary do anything apart from phoning and browsing internet).

I did follow that link but did not solve anything for me. Step 6 says to make another copy of the ".nv_data" file but I have no such file, the file I have is ".nv_data.bak" ... is this normal? I am afraid by copy of EFS is also corrupted as I did it after the problem appeared and after I had factory reset the mobile the first time.
Edit:
Also the default EFS folder I get generated after the reboot does not have all files I have in the backed up EFS file (for example I do not get nv_data.bin.md5)
Can I copy the efs folder from one mobile to another (for example from a Samsung Galaxy ACE to the Samsung Galaxy SII)??
The .bak file is a backup of your previous file
Rename it to remove the ".bak" part and hope for the best.
BTW - water damage is very serious matter. I suggest to remove the battery, SD card, SIM and put the phone in a jar of rice (completely covered by rice) for 48h at least. Rice will absorb all moisture from the device.

Thanks for that info ... will try that hoping no permanent damage has been already done.
Just another quick question: I am afraid that my copy of EFS folder is also corrupt (as this was done after the accident and after I had factory reset). Is there a way how I can set this up in memory AFTER the mobile is on? or can I copy the EFS folder from another samsung mobile (I bought a Samsung Galaxy ACE as a replacement and was wondering if I could copy the EFS folder of this onto my Samsung Galaxy S2)?
Factory reset does nothing to IEMI files - it deletes all the app settings and app data.
Focus on restoring your original efs. I'm not sure that SGS2 and Ace are compatible for efs "transplant". It's worth a shot (after backup).

I can check if someone at work has a Samsung Galaxy S II like mine and is happy to give me a copy of his EFS folder. That should definitely solve the problem if my problem is with a corrupt EFS folder right?

No it won't work. Take it to a local mobile shop and give them a small fee and they will fix it. Also water damaged is not good as stated above.

Thanks for your answer, just out of curiosity ... why wouldn't it work?
Because the IMEI is a unique hardware identifier I.E one IMEI for every mobile device on the planet, his EFS folder contains details pertaining to the IMEI attached to his phone. Even if you could do it, you'd end up getting both IMEI's blacklisted rendering both phones useless (good luck getting them unblacklisted).
Pay the small fee as advised to have someone fix it.

This is not about paying a small fee, I actually already bought a new mobile. I just would like to try and fix it for the fun of it!

I understand what you mean ... but ... if I do the copy of the efs folder, remove simcard, turn it on, enter *#60# then I should see the same IMEI number as the one of the other mobile without blocking the IMEI number (as there is no simcard). Then all I would have to do is see how to replace that IMEI number with my IMEI number by using the steps suggested in the second post.
It won't work because the IMEI is baked into the hardware. You're thinking about it in a simplistic way, and it doesn't work like that.
You're venturing into rather dubious territory discussing changing IMEI's, which is forbidden here (because it's illegal, even in the manner you're suggesting), I suggest you steer away from that, lest mods close your thread.
Your phone can be fixed (the IMEI/EFS can be re-written to the device), but it requires specialist hardware to do it, which you can either pay for & stumble around to try and learn how to use it without permanently borking your phone, or you can pay someone who already has the equipment & knows what they're doing 20 quid to do it in 10 minutes.

Do not want to be doing anything illegal. I will follow your suggestion. I bought the mobile as part of a contact from Vodafone (no longer under warranty) should I take it to them?
Note: USB does not work. I can charge it but PC does not recognize it. Would an IMEI/EFS re-write still be possible? or I am better off finding a motherboard over ebay?

Yes, you must be right. I though IMEI was stored in a file not burned on a chip, can't understand how the hacks i found on the net work if IMEI is stored on a chip.
No. They'll send it to a Samsung service centre (like Vodafone do here) & they'll charge you an arm & a leg to fix it. Ring around local mobile repair shops.
In that case it might need a USB port replacement, which is cheaper than the IMEI fix (you could do this first yourself, then pay to have the IMEI/EFS fixed) if you do it yourself. There's been a bunch of threads on here over the past 12 mths, search for/read those before you do it, you need to order the right part & there are 4 revisions.
A motherboard replacement with a board sourced from a 'donor' phone/phone with a broken screen which is otherwise OK for example is doable & relatively cheap compared to having a service centre put a new motherboard in (your IMEI will change if you put a 2nd hand board in which is OK/not illegal or anything)
The EFS stuff relies on the the stuff in the chip not being scrambled/corrupted (which invariably happens in these situations).

Thank you very much for your answer. I will take my chances and open it to see if I can fix the USB. After that I hope to find a repair shop that can re-put my IMEI back on the mobile.
Thanks again.
Hello all, GREAT NEWS! I opened my Samsung Galaxy S2, was going to remove the main board when I noticed that a connector with label JB55 looked like had some corrosion (not sure if that is what its called), just brushed it a little, re-connected, a pop, I had my IMEI back
However I noticed that reception is low, just get one bard where usually had three. Does anyone know what module determines reception?
Still not working is USB connection with PC (I will replace that USB port) and WIFI and Bluetooth! ... but hey I can phone
