It is Illegal and no

There is currently no way to do this as the algoriythm of the EFS nv_data.bin is unknown publicly. I may attempt to dissect it for resurrection purposes one of these days.

i could be wrong but i think the poster wants to restore their original IMEI that was likely changed to a generic by a particular flash.
I think it would be hard to make the argument that changing an incorrect/corrupted IMEI back to the devices original/proper imei is illegal.

If thats the case, there are a couple threads on restoring it and the nvdata files.

I know...one of them is mine =)
I haven't been able to fully test on a gingerbread rom because i haven't ended up witha corrupted imei on one. I have had the improper product code on every GB rom however and did test this and it will fix your product code on a GB rom. In the past i had corrupted IMEI's on froyo roms and using this fix to restore product code always restored my IMEI to its original as well. Its worth a shot if you have corrupted product code and/or imei on GB. It just test on mosaic and fixed my product code to the proper US ATT code.

[Q] Baseband?

Hi, I'm really not sure which baseband to use for my O2X
I'm running CM7.1, and I have been reading a few things that changing the bb might make things a bit better (reception/call quality/etc).
Does anyone have any suggestions and is it a risky process? Would I need to reflash my rom & will I lose all my settings unless I do a NAND backup/restore?
Thanks,
brezzo

Flashing BB will erase the user space so you'll have to restore a Nandroid Backup after. It takes 10 min maximum, not very hard.
If you're using CM7 a Nandroid Backup is correct, as it uses standard ext4 format for partitions. And then you'll have exactly the same phone but with a new baseband, last thing is to install matching RIL with GetRIL market app, only a matter of seconds.
I can't give any advice on which BB to flash as is it very variable among people... The gold rule is that if your sound during call is good, your network accesses are good, no need to change.
CM7 works with any BB it's just a matter of opinion. Many users seem to have latest 0823 BB, but some use an old Froyo BB as well...

Thanks mate, I currently have 405 and I have no idea if it's froyo or not, but I think it is. It seems to work fine so I don't think I'll go through the hassle of changing.

i have got this app on your recommendation and it indeed says my RIL doesnt match by baseband. If i click the button within the app for download and install new RIL will this wipe all my data? or will it just replace the RIL??
many thanks

[Q & S] Swapping IMEIs between 2 Captivate?

Questions and Suggestions.....
I just got a second captivate, this one WITHOUT a cracked screen!! Now i realize i could just teardown and swap the main board, or the digitizer itself, but... that would be too simple!
Or i could just call my provider and change my imei with them... but who wants to talk to their provider??
Or.... i could do something fun and learn, by cloning my phone. from what i understand, all i would need to change is my IMEI, contained in my EFS.. and i have several backups of my good efs, and could easily backup the new one.
Is it simply as easy as copying the efs folder over with root privilages? or better to do an ADB dd (data dump) then tar it and odin? or ADB push/flash....
Is there anything im not considering? Is there any real risk if I have my EFS backed up? Any other ideas? suggestions? discussion?
any neat/interesting things to do with a copied phone set?

I have mine dd'ed and ready to flash with heimdall(i don't think ODIN will touch the EFS partition, but Heimdall will if you put it in there) So IDK, I would talk to conexxion2005 or AdamOutler about this!

thats what i was thinking...

Yahh, Or contact Benjamin, I forgot his last name, but he made Heimdall

Just dd the efs partition and flash it with heimdall. Thats all you have to do.
Code:
dd if=/dev/block/stl3 of=/sdcard/sdext/efs.rfs
do the same with your new phone to make a backup of it. Change the name of the efs file so you dont overwrite it. When you get done, swap the serial number stickers. I didnt tell you all this. Its illegal

it's personal development for learning purposes.
This is why I value second opinions.
now to get 2 (active) sims for the same imei.....
they both have ICS RC3.1 on them ive had the one a few hours.
one with silver speaker mod, one with out. if you dont know silver speaker mod, GO FIND IT NOW! READ THE FIRST 4 PAGES AT LEAST!

this is what ive been dealing with for the past 2 months......
but it works just fine....
I dropped it a good 10 feet, but it was fine, 20 minutes later took out of my pocket to see this...
http://dl.dropbox.com/u/19201431/Images/cracked%20to%20****%20but%20works.jpg

Lol my sister's looks exactly the same!
Just flashed it yesterday, it's weird to feel all those cracks under your thumb, and it still works.

I'm not sure DDing then flashing it to another device will have the correct effect but it's worth a shot. I can do remote IMEI repair for the Infuse and Vibrant 4G but their EFS structure is different from the Captivate. I know for a fact you can't just throw nv_data.bin files around and expect the IMEI to follow as it won't. However, DDing the zone then flashing could result in the desired effect.
LET US KNOW!

How would I know for sure? By checking the about> phone?... Running ice cream sandwich so I'm not sure if the dialer codes will work

I wonder if any of this would help me with my borked IMEI? I'm on the network default IMEI (the one ending in 0000) and I really want my original IMEI back...
Any ideas?

Do you think it would help flashing to stock including CSC files? Then immediately booting into stock recovery to force it to apply this CSC?
I know it does some funky things in that first recovery boot.. Applying settings and such...

[Q]Back to stock. (How-To for a broken USB port)

Okay, so here's my issue. The usb port in my phone is dead, and I don't have 30 bucks to send it to mobiletechvideos to fix it. I also do not have a soldering iron, solder, and a desoldering braid to do it myself. Therefore I cannot use Odin via my computer anymore.
I downloaded Mobile Odin Pro v3.00, and becuase I am on Cyanogenmod 9 (REMICSv1.3) I am unable to load Mobile Odin. It states that it did not expect the file system and closes. To my understanding this is a failure of the APP/App maker (Chainfire) becuase the app does not know how to recover from a MTD to BML conversion. (And by failure i just mean it doesn't work, I am not implying he's bad or the app is bad). I'm really hoping that he can figure it out, 'cause right now I'm stuck with pure ICS roms (And I hate the look of ICS, hence using a TouchWiz themed ICS rom...)
So, with that said...
Is there (and this is high hoping) a CWM flashable .zip that will convert from MTD to BML that I could use?
Process would look something like this:
1. Power phone off
2. 3 button boot into Recovery
3. Wipe data/factory reset
4. Flash zip (MTDtoBML.zip)
5. Reboot into recovery
6. Flash Gingerbread rom
7. ???
8. Profit.
I ask becuase I don't want to be on ICS anymore. It has more issues than my grandma's back, and I just plain old enjoy gingerbread. (flash addict).
If so, could someone direct me to the zip file, or at least explain why this is or is not possible?
Kind of fiending for some old school Cognition or Perception (can't find active DL links), or maybe some old gingerbread roms...
Thanks,
Arisenhavok

Bump.... any ideas?

If you don't like ics, try miui, cm7, or my phrog or phobos roms. All use mtd, and you should be able to flash from your cm9 setup to one of them.
Fyi, it may take two flashes for the room to "take".

I've taken a look at both lewa and phrog and they seem yo have a significant issue or two listed in the op. Miui is EOL if I remember. I guess I'm more geared towards a BML RFS Touchwiz rom. But I suppose I will once again have to try looking for another mtd rom

I'm in a similar situation as OP except the radio also doesn't work apparently and have been wondering what I can do with it aside from just use it as a wifi-enabled media device. Since we're able to overwrite as least SOME files in the efs folder (nv_data.bin), I got to wondering if I could replace the entire system partition (or as much as possible) with a known good one (I have a second Captivate that works fine) to make certain there's nothing in software that is messing with the radio. So I'd copy everything from the good phone to SD card and then from SD card onto bad phone. I assume the only major hurdles other than inability to write some open files perhaps would be the SN & IMEI. If I can locate where those are kept, I could edit before copying. Being new to smartphones and this OS, there must be something I'm missing since this seems so simple.
And yes, I've flashed 2 other CM ROMs (I bought it with one on it) and flashed different radios but it never sees the service. It is also unlocked.

Replacing the efs partition will only at best get you to a generic imei. Your cell radio gets no signal because the efs partition and radio don't communicate or there's a hardware issue. Best bet is to send it to mobile tech videos and let them fix it for you. It's cheaper by far than a new phone.

Unlocking it may have also broken it. Probably why they sold it in the first place. Best bet is to use it as a wifi media player with apps and games unless you plan to send it out

I have 3 other phones I can use so it's not worth sending off. I figured I'd resell it for parts so I wasn't concerned with bricking it. I was hoping to verify whether the radio would work or not to get more money out of it. What controls whether the efs can communicate with the radio chip? Drivers obviously, which is what I gather flashing a new "radio" does. What file in the efs controls radio comm that could be corrupt?
I guess I should also specify by no service, it's not the circle and slash, but 4 gray bars. Phone status shows network as unknown (it will not find any when you do a search) and disconnected. SIM card works in 3 other phones and all 6 contacts seem fine in the suspect one. WiFi and GPS work OK. Maybe I should disassemble and verify antenna contact is good?

He'd claimed it was because of the bad USB port. I've never read about unlocking rendering the radio useless. I'll have to look that up. It seems so simple to unlock these Galaxy S series.

[Q] Disable IMEI check on Jelly Bean ROMs

Hello guys
Is there a way to disable "Wrong IMEI Notification" on system startup?
I know how to restore IMEI, but my network works fine with generic IMEI, so I don't care about it much.
The only thread I was able to find is here:

It's about 4 months old and no answer is given.
Currently I'm running Helly Bean 4.2.1 (Release - 05.01.13)

It's cooked into the system apps, so unless someone has the knowledge to change it, the answer is no.
Fixing the problem is quite easy though and takes 15min at most after a good TiBu backup, if it gets too annoying, take that extra 15min

I was on Helly Bean 4.2.1 and it was giving me an error message because of wrong IMEI.
I didn't have efs backup, so I backed up everything and flashed stock kk4 assuming that it would restore my IMEI, but it's still 00499...
So how do I restore my IMEI?
No it's not refurbished.

That's actually how you restore your IMEI.. By flashing Odin KK4. Did you restore anything after flashing?
I went ahead and did a little google search (which can go a long way ). Here's what I got: http://forum.xda-developers.com/showpost.php?p=24175451&postcount=2

Umm Your file explorer probably doesn't have root rights if you can't see those or you have to show hidden folders in settings.

I'm using ES File Explorer (root settings were checked, permissions granted) and Yes, I rooted device (first flashed corn kernel).
Already flashed HellyBean 4.2.1 (10JAN13). Will take a chance after restoring backups.

Just tried to do like described in the link - folder /data/radio is empty for me, unable to find /factory folder
I wonder why flashing stock kk4 didn't restore IMEI ((
I backed up efs folder after installing Odinkk4, but I don't think it can help.
Good thing is that my carrier works just fine no matter IMEI
Anyway, thanks for trying to help me out. :good:

@archildroid, Josh at Mobiletechvideos.com I believe can restore your imei without having a back up. There will be a charge for it, but next to Adam Outler, you won't find a better set of tech fix it hands.

I have tried lots of methods to restore my IMEI, but no luck.
One thing I encountered: This wrong IMEI popup has "Galaxy S Settings" icon in the corner, so I froze it with Titanium and the popup disappeared.
Of course you lose all the abilities, that Galaxy S settings have - TV Out, Color tuning etc.
I hope someone with sufficient knowledge will modify Galaxy S Settings, to disable this popup.
P.S. Before changing anything in system apps, MAKE NAND BACKUP, I'm not responsible for anything you do to your phone!

Usually, going back to stock KK4 with Odin fixes your IMEI problem. Once there, you make a backup of your efs folder and you're set for your android's life. It's a one time backup (as long as you don't delete it..) and can be restored whenever.
