I'm working on it
[Nexus S Android Development] NexusCrazy:
I'm one of them, |I noticed no service straight away wen i installed NexusSence but liked it that much that I did a Nandroid back up so I could go back n have a proper look round when I had more time, and then I reverted back to Cyanongen Nightly and thats when I noticed the problem had stuck, Dont know if my nandroid could help you figure this out.

Am devastated at the moment as you can image :(

Sweet...nice rom...first time i'm using Sense and liking it. I use my Nexus S for flashing roms and playing around and also have a G2X. But after seeing this rom...might well return my G2X and buy a sensation when it comes out :D

Anyway, on this rom even i'm not getting data network...checked in settings and mobile data was enabled. Also, when i go into Mobile Networks ->Access point names, it says "NO Sim card found. Please insert a sim card..."
[Nexus S Android Development] truthkillszz:
idk why but since i flashed .3 i cant access my recovery at all. it just shows a black screen and wifi is working but i cant download anything from the market or even from the web but i can view websites.
[Nexus S Android Development] apreichner:
Does anyone else have data issues being lost on all roms because of this?
[Nexus S Android Development] truthkillszz:
i cant even access my recovery and i noticed i am on the same recovery that those other guys mentioned also 3.0.2.4

edit: managed to finally get into recovery after manually entering recovery and letting it sit on a black screen for 5 min. going to flash cm7 and let you know what my issue is with data also
[Nexus S Android Development] bloodhawk:
Any idea where i can find the required files for the Nexus S? They are talking about the Galaxy S there.
[Nexus S Android Development] treUse:
Here is the screenshot.

I wonder, did all of you who had problems come from CM7? May be a long shot though...
[Nexus S Android Development] :
No, but I also made a nandroid backup of my previous rom before flashing. I'm using data right now.

-Remember, Android hell is a real place and you will be sent there at the first sign of defiance-
[Nexus S Android Development] apreichner:
I'm checking to see if we can use other peoples files.
[Nexus S Android Development] bloodhawk:
Yeap, you also have the T-Mobile version.

Mine is a UK version. Anyone here who has the UK one?

Though thanks for your help.

@apreichner

Thankyou so much for the help.
[Nexus S Android Development] apreichner:
Thank you for being understanding.
[Nexus S Android Development] bloodhawk:
Im trying to go the Odin way, will keep you posted.

@apreichner

Is it possible if can have your IM handle or something, i can keep you posted there much faster.
[Nexus S Android Development] IT4ALii3EN:
Please, the link is dead (it isn't possible to download because the link isn't on the img.)

Can I the link for the Nexus Sense 0.3 :) ?
[Nexus S Android Development] treUse:
Good luck, I hope it works.
[Nexus S Android Development] apreichner:
Don't download and flash.
[Nexus S Android Development] foxehkins:
I just seem to be stuck on edge after reverting to cm. Wondering if it is a tower issue so I'll wait awhile and report back.
[Nexus S Android Development] fabrizioo2007:
Do you suggest to those who haven't any service iussue to flash another Rom at the moment?
[Nexus S Android Development] bloodhawk:
Dont do anything right now. An keep you most recent working Nandroid backup (ROM backup) handy.
[Nexus S Android Development] apreichner:
Does your nandroid work? Or did you not backup?
[Nexus S Android Development] bloodhawk:
Nope it doesn't. Because the /efs isn't backed when using Nandroid as it is :(

I did make do a nandroid backup before flashing. I do it every single time.
[Nexus S Android Development] murdoch1:
Have tried a number of nandroid back up's. None work. They all have the same issue, no mobile connection. It looks like the IMEI number nv_data.bin was overwritten or deleted when I installed sense3.
[Nexus S Android Development] truthkillszz:
restored a backup of miui and i can only connect to edge
[Nexus S Android Development] apreichner:
Do you have a Backup/EFS on your sd card?
[Nexus S Android Development] murdoch1:
Hi....sadly not. Never had to have one before, hindsight would be a wonderful thing.........Ive flashed loads of roms and never experienced this before....hoping you can save our phones.......im on orange uk, installed flash via clock 3.1.0.1 directly...not within rom manager.
[Nexus S Android Development] :
My nandroid works. I had CM7 as well. I'm using 3G as well as we speak.

For all of those others using CM7, I'm using the recovery version 3.0.0.5.

-Remember, Android hell is a real place and you will be sent there at the first sign of defiance-
[Nexus S Android Development] apreichner:
That's weird, because neither did I.
[Nexus S Android Development] bloodhawk:
Alright. Flashing through Odin also didn't help. The PIT file isn't there.
[Nexus S Android Development] apreichner:
Guys could you check your /efs folder and tell me if anything is there?
[Nexus S Android Development] apreichner:
Was yours not working but a backup fixed?
[Nexus S Android Development] truthkillszz:
just flashed a clean copy of cm7 and when i went into mobile settings i realised use 2g networks only was ticked off already and my apns were set to simple mobile already. once i unchecked the 2g only and fixed apns data was working fine

which file do you need from efs?

edit: nvm after a few min it went back to edge
[Nexus S Android Development] murdoch1:
Hii have the following files/folders:-

[Nexus S Android Development] gregounech:
Guys, I think I have a solution for you, flash a stock ROM in Odin ticking Phone EFS Clear.

EDIT : I'm not sure at all about this, but this is probably the option to overwrite the efs folder that is being corrupted on the ROM.
[Nexus S Android Development] NexusCrazy:

[Nexus S Android Development] bigmizz79:
I had a problem with my signal..I reverted back to a older nandroid backup before the clockwork update all seems good now..crossing fingers

[Nexus S Android Development] :
I'm not sure, I just restored a backup after I needed to get some important contact info. Where is the folder you want us to look into?

-Remember, Android hell is a real place and you will be sent there at the first sign of defiance-
[Nexus S Android Development] bloodhawk:
Doesnt.

Im trying the Phone EFS clear in Odin Will update in a minute.

@NexusCrazy

Sent you an add request over Gtalk.
[Nexus S Android Development] apreichner:
Heres the issue guys. The theory WAS the rom wasnt backing up the EFS before restoring. The only issue is that from one of the people, their EFS folder isn't empty, and neither is mine. I'm currently researching.
[Nexus S Android Development] apreichner:
You may end up screwing it up even more, check to see if your EFS folder exists first.
[Nexus S Android Development] bloodhawk:
Yeap the EFS folder is there, with the nvdata.bin and nvdata.bin.md5 files in it. I have them backed up though.
[Nexus S Android Development] gregounech:
Don't blame me if it bricks your phone.

EDIT : Yeah best way is to back up your corrupted efs folder before doing that & if it screws it up more then put it back using estrong / root explorer.
[Nexus S Android Development] bloodhawk:
Lawlz, dont worry i aint blamin anyone. :P

Anyways it didnt help :D
[Nexus S Android Development] gregounech:
I have no idea if it'd help if someone upload their efs folder, as the files are encrypted.
[Nexus S Android Development] kirdroid:
Im also getting only edge aftet restoring my backup rom. I do see the efs folder however.
[Nexus S Android Development] NexusCrazy:
so whats hapening is Odin abe to sort it?
[Nexus S Android Development] bloodhawk:
Nope it didn't. :(
[Nexus S Android Development] Gonizahavy:
me too, gprs only, efs folder exists
[Nexus S Android Development] foxehkins:
Same thing here. Every now and then I briefly see an H pop up like its trying to connect so that makes me think its a tower issue. Been staring hard lol
[Nexus S Android Development] apreichner:
Make sure Use 2G Networks only isnt selected in your mobile settings.
[Nexus S Android Development] Gonizahavy:
it is not.. i've used the 2g/3g toggle to try to get a 3g signal, no luck
[Nexus S Android Development] apreichner:
Check your APNs as well to make sure its set to your carriers.
[Nexus S Android Development] bloodhawk:
I have given all hope now.

Tried almost every thing a general user can.

Lets hope @apreichner is able to come up with something, otherwise ill have to use my Nexus S a mp3 or something. :(
[Nexus S Android Development] Gonizahavy:
checked, it is
[Nexus S Android Development] bloodhawk:
Anybody here with a UK Nexus S not having this issue and with the IMEI still intact?

If so can you please forward me your nvdata.bin file?
[Nexus S Android Development] apreichner:
Is your ROM showing an IMEI at all?
[Nexus S Android Development] bloodhawk:
Yeap 10 chars.
[Nexus S Android Development] apreichner:
Check the back of your phone, it should list it.

Remove your IMEI from the post
[Nexus S Android Development] NexusCrazy:
I need a beer mate, if I lived near u I'd suggest the nearest pub and get wankered as I've no idea were u live I'm going to the offie for a few beers.

what a day
[Nexus S Android Development] kirdroid:
Ok just came to my work place ... and checked I'm getting 3G and confirmed the same used speedtest app to see if i'm getting 3g speeds.

At my home 3g signal is pretty weak and that may be the reason i was getting edge, i use wifi mostly at home so had never observed that i get edge most of the time.

So, for me restoring to my backup rom seems to have resolved this issue.
[Nexus S Android Development] NexusCrazy:
Yeah mines the same here
[Nexus S Android Development] bloodhawk:
The real IMEI is there. Aswell as on the box.

If we can somehow compare the nvdata.bin from a properly working Nexus S and figure which device details are messed up, i think we can work out a fix like the Galaxy S one.

Because right now the IMEI is falling back onto the fail safe one. Because some or the other detail is being messed up.
[Nexus S Android Development] apreichner:
Remove the IMEI from your post.
[Nexus S Android Development] dopeypopey123:
i flashed as soon as it got put up and just came back on to find this and i also have the imei number issue :(

not good as i just lost job and have little money for a replacement i really hope we find a fix!!! :'(
[Nexus S Android Development] apreichner:
Somehow we all got the same IMEI, the phone must've restored it some how
[Nexus S Android Development] bloodhawk:
Dont worry the bad IMEI shouldn't be a point of concern, since its the same for almost every Samsung phone :)

As for the phone restoring it. It is a fail safe IMEI, when the device details do not match the ones hard coded into the hardware.
[Nexus S Android Development] apreichner:
Alright, I'm going to investigate ways to fix as it looks like we are all having issues.
[Nexus S Android Development] bloodhawk:
Hey please dont worry about people blaming you for all this. Things like this happen. And they dont happen to everyone. All we can do right now is cool down a bit and look for a solution! :)
[Nexus S Android Development] dopeypopey123:
I dont blame you it is just a human error :)

thanks for all your hard work and i do hope we can fix this
[Nexus S Android Development] NexusCrazy:
agreed, but it helps when the Dev is concerned and wants to help.
[Nexus S Android Development] apreichner:
I'm working on seeing if there's a way to fix. I contacted one of the devs.
[Nexus S Android Development] treUse:
If there was a fix for the Galaxy S, there has to be a way to restore it on the NS as well, I hope.
[Nexus S Android Development] NexusCrazy:
Thanks it would be very much appreciated.

And what a shame man, as the ROM is looking and running so smooth.
[Nexus S Android Development] Byte_76:
Hi All,

I also flashed before this info came to light. My IMEI in settings - about phone - phone identity does not match the IMEI on my box or under the battery however I do get signal and I can make/receive calls and send/receive sms's.

The flash process I followed was to flash from rom manager which completed but then stayed on the Google screen. Then I pulled and replaced the battery and booted into recovery, cleared data and cache and flashed again after which the phone started successfully into the OS and that is how it is at the moment.
[Nexus S Android Development] Byte_76:
Apart from the IMEI issue this is a great ROM, thanks for all the work you put into it, much appreciated!
[Nexus S Android Development] apreichner:
Yes it doesn't cause problems now, but it may cause problems in the future.
[Nexus S Android Development] cgi101:
Just a word of caution: I accidentally wiped my /efs/nv_data.bin on a Samsung Galaxy S Captivate. After it was wiped, I was no longer able to make emergency 911 calls. All calls would work except for 911 (or variants like 112). I'm not sure if this problem would carry over to the Nexus S, but just be warned.

If you were ever in an emergency and your phone wouldn't dial 911, you could call 411 for directory assistance and ask for 911.
[Nexus S Android Development] bloodhawk:
In some countries the changed IMEI will work, but in some it wont.
[Nexus S Android Development] bigmizz79:
So everyone has the same imei#???if so what can be effects of this?? I still have 3g..but it seems my cell signal keeps dropping..maybe it was always like that but I notice it now..!!!
[Nexus S Android Development] fabrizioo2007:
I've restored my backup (of the end of April)and now all work fine...both 2G and

3G works fine..Can be usefull my backup (there's Rom iceandfire 1.1)?I have

clockworkrecovery 3.0.0.5 and I don't have installed the updates of recovery from Rom

Manager...
[Nexus S Android Development] LoveisPeace2012:
We all make mistakes we never stop learning. Hope we can resolve this :)
[Nexus S Android Development] apreichner:
It has no effect on 3g signal.
[Nexus S Android Development] treUse:
It works here in sweden, but the signal is very irregular.

Are there any longterm effects this will cause, and if so, how severe?
[Nexus S Android Development] bloodhawk:
It would be great if people can actually check if they have the borked IMEI. That would be way better in helping in resolving the issue.

Goto About Phone > Status > IMEI .(tally it with the one on the box or the one under the battery)
[Nexus S Android Development] treUse:
I certainly have it, no doubt there.
[Nexus S Android Development] fabrizioo2007:
no,My IMEI is the same written same post up by (don't remember who)...but all services and data connection seem working well
[Nexus S Android Development] Gonizahavy:
I've got this too.
[Nexus S Android Development] bloodhawk:
Luckily for you guys it's working in most of he countries.... though here in India... Ian using my phone tolisten to music and play fruit ninja! :(
[Nexus S Android Development] bigmizz79:
I also have different imei# than the one on my box and under the battery
[Nexus S Android Development] apreichner:
I am deeply sorry for all issues.

[Nexus S Android Development] Zehlek:
I am currently running infin1ty data and everything currently works perfect. My IMEI doesn't Match anymore and in efs/imei is empty. In settings I now have one in settings that ends in 40000. Anyway to fix it?
[Nexus S Android Development] nitsuajd:
Yes, my phone service works
[Nexus S Android Development] salahag:
Like mentioned before, seems most (or all) of us have IMEI changed. If everything is working fine with the Sense rom, keep it as is for a little while just in case and hopefully a solution will come up soon.

BTW my phone serial number is different too.
[Nexus S Android Development] Zehlek:
Also I cannot download anything in Market anymore :-(
[Nexus S Android Development] apreichner:
Even on a different rom?
[Nexus S Android Development] apreichner:

[Nexus S Android Development] Gonizahavy:
Market works here too
[Nexus S Android Development] nitsuajd:
Working ok for me too
[Nexus S Android Development] Zehlek:
It continuously says unable to download due to file not found. My APNs and data are correct. I am using wifi to download in market.
[Nexus S Android Development] salahag:
Just tried Whatsapp and got the following message:

Connection failed! If you have installed Whatsapp on another phone, please delete and reinstall. Warning: Do not use on multiple devices with the same number.

I restored Whatsapp with TB, seems it identifies phone using IMEI :)
[Nexus S Android Development] Gonizahavy:
hava you tried a different item to download?
[Nexus S Android Development] Zehlek:
Yes I tried 5 different apps and still get same error :-(
[Nexus S Android Development] Gonizahavy:
have someone already tried flashing the stock 2.3.4 .zip file from google?

I flashed 2.3.3 and it didn't help. I got a system update and updated to 2.3.4 and it didn't help either
[Nexus S Android Development] Zehlek:
Did your imei change from what it was on the box or under battery?

[Nexus S Android Development] Zehlek:
Thanks. Do you know where or how we can acquire an original?
[Nexus S Android Development] :
Couldn't we just wipe EVERYTHING besides recovery from the bootloader then flash a new rom from recovery?

[Nexus S Android Development] :
Why not? Not wiping data from recovery, but from h-boot. Or is it fast-boot?

fastboot erase userdata

fastboot erase cache
[Nexus S Android Development] deeren:
Fastboot erase userdata equivalent to factory reset but it doesn't touch system i think.

Fastboot erase system.

I might be wrong though.

I do hope the 3rd link would work. I'll pray for an Odin miracle. Will try tomorrow.

erasing system with fastboot didn't work either. Still fake imei

Im gonna try this rom... i come from SuperAOSP.
[Nexus S Android Development] deeren:
Warranty sir. Even if i go to Samsung for repairs( which i can't cause i got it from the us), i can already see them saying that it is a different phone cause the imei don't match the one on the invoice.

Of course, there are other disadv too like applications required to run on only 1phone and which checks for imei for identification.
[Nexus S Android Development] Gonizahavy:
do not flash it just yet, read comments first!

I believe that Samsung will repair this for you, because the original IMEI is written on the back of the phone..

[HIGH PRIORITY announcement] anyone flashing roms
[Nexus S Android Development] :
I wonder how we can restore our old imei numbers...

-Remember, Android hell is a real place and you will be sent there at the first sign of defiance-
[Nexus S Android Development] ivanmmj:
I figured it was time I said a few words to try to get some things clarified.

I really don't know why Samsung uses the /efs partition to store such important information... Why not write it into something more permanent?

The /efs partition stores the IMEI and usually the WiFi and BT's unique MAC addresses. The wrong IMEI means that:

1. Apps that check the IMEI will fail if they see more than one person with the same IMEI.

2. The provider may ban that fake IMEI because they would detect duplicates in their network. This would cause you to loose the ability to get calls and get data services.

The Samsung Spica people had the same issue happen and they had someone figure out how to edit the nv_data.bin to have the correct IMEI. Technically, PURPOSELY changing your IMEI is illegal but I don't see a problem with you RESTORING your IMEI after an accident like this. I think the best next step would be to contact the author of THAT project and see if he's willing to help you guys out.
[Nexus S Android Development] Zehlek:
The main question is how do you restore your imei
[Nexus S Android Development] mak213:
LMFAO i think this is hilarous i already flashed but reflashed to miui but god dam thats sick never heard of that being a bug in my life imei being changed lol one for the books hope this gets fixed ASAP! lol this could be an issue when i want to get my phone replaced
