Im having issues with a Galaxy i9000, the problem is that it wont get any signal at all. It just shows the circle with the line across it. The phone is unlocked, and i can tell i already tried about everything.First of all, it does show the right imei number, but for some reason when i try the stock ClaroPR firmware it when it gets into recovery it has 2 diferent csc folders. But it applies the KOR csc instead of PCT which is the ClaroPR csc. So then i apply the PCT csc with csc select apk and it changes the csc to PCT, but i will still have no signal. Everything is correctly mounted i think. Because i deleted the efs folder with Root Explorer and the phone created a new efs folder with the nv_data and nv_data md5 files. Does someone has an idea on why is this happening?
you'll need to restore the efs folder if you made a backup.

I will suggest a complete reflashing of firmware.

Thats the funny thing, i already did that a couple times. And none of that worked. Trust me i used the stock firmware, the ClaroPR froyo and also the gingerbread version. No luck at all, thats the main thing, its a very strange issue. It is still showing the right imei number and also creates a new efs folder if i delete it. Which in some cases ive seen none of that happens. But still no signal. Weird huh?

Where did you get the phone from? Sounds like it might be a blocked imei
Sent from my GT-I9000 using xda premium
Yeah, also thought of that. But then, if the imei was blocked then the phone being unlocked is supposed to grab other companies signal. And it doesnt.

I think imei block is global, as the imei isn't related to carrier, it is a global id

Well, i guess that might be it then. But i think i have seen that before and after the unlock the phone will accept other carriers. Anyways, i dunno how this happened since the phone its not mine so im running out of tricks to make it work lol.... So i will ask the owner if this phone is legal or an alien he bought in the streets lmfao... Thanks guys!

Phone was unlocked by the Galaxy S Unlock app.
And the signal is very poor, usually only one bar or no signal.
I've tried a few modems, but the result seems on change.
I found my IMEI is 0049990........
Product code: SGt ActiveAATT
Does a fake IMEI related with signal?
How can I fix the signal problem?
It is quite possible members on xda have faced connection problem with the generic imei, You can only restore the original imei if u had ever backed up the efs folder which contains the NV_DATA.BIN. If u don't have the correct NV file then its not possible to restore it, You can contact connection2005 he can repair it.
Or you can try this method people have said they were able to restore it with this but it dint worked for me when i once tried it.

I tried the method, but still unsolved.
Because I lost my nv_data.bin, there is no any way to edit nv_data to get my IMEI back?
You have to contact connecxion2005 he can do it. Search for mobile tech videos on youtube he is the guy who can help u.

I just have UnBrickable Mod from mobiletechvideos last week.
Before spending money to fix, is it any help to replace my nv_data.bin with other phone's?
I find a nv_data.bin of UK version i9000, and I'm trying to replace with it now.
I mailed to mobiletechvideo.com and ask.
They said the signal problem is not related to IMEI, and I should try different modems.
So what modems could fix this problem?
What ROM are u on?

I've tried SensatioN, Illuminance, Espresso, and stock JF6 & KJ3. The signal problems are the same.
Is kj3 (i987 base rom) the one ur currently running? If so try kb1, kf1, kh3 ... the captivate modems, if ur on a i9k rom then use the i9k modems kc1,jk4 ,jl2 ,kg3 (the popular ones)...

It won't work
Even if it did, that would (most likely) change the IMEI, which is illegal in the United States and several other countries
Basically, your IMEI has to be rebuilt using either Connexion2005's services or one of the SPT/RIFF box kits.
My phone is the same way; the more I think about it, the more I suspect that ATT just sent me a device with a broken IMEI. My EFS backup from when I first got CM7 says the generic IMEI and has the product code line completely broken anyhow.
I would be very appreciative if someone could post the segment of their working NV_DATA.bin from address 00188000 to 00188030 so that I can correct mine to what it should be; the 188008 fix frequently linked to on this forum did not finish the job.
EDIT: I just noticed that my EFS backups seem to be tied in SOME way to the CSC flashed to the phone... Does anyone have the latest I897 ATT CSC?

You can dl the firmware from www.samfirmware.com
I don't know about all g the latest leaks, but I know kf1 has the csc file in it.
Or
Download t the Odin 3 file version of KF1 in my sig.I it has it in there. If you aren't registered at samfirm, that would be the easiest way.

Just as an update:
The samfirmware.com site is going to be defunct soon (end of 2011), and all its information will move to a new site: www.sammobile.com. If you had a samfirmware account, you'll have to re-register at the new site. Sounds like they'll have all the firmware at the new place like before, just a new name/site.

No, I'm not meaning data connection. I know I will get edge only.
I mean the phone signal itself is very unstable, sometimes no signal at all.
Well try flashing different modems... I will help you through this.

I'm trying a few modems from this thread: http://forum.xda-developers.com/showthread.php?t=1300843
Most of them have very poor signal or no signal at all. Few can have 1~2 bars of signals sometimes.
I tried those until now:
je5 0~2 bars
jf1 no service
jf6 no service
jh2 0~1
jh3 0~1
jh7 0
ji6 no service
jj4 1~2
jl1 0~2
jl2 no service
kb1 0
ke3 0
kf1 0~2
How I use the modems is download them into sdcard and flash through CWM. Do I miss something?
Or any other issue I didn't notice?
Have you tried RAT selection? This is a workaround for RAT on I897 modems.
Hi everyone,
I have a Rogers (Canada) Galaxy Captivate. I flashed to Serendipity VII, and my CSC is now showing "Unknown", and /system/csc is missing.
I roam with the phone a lot, and I use other countries' SIMs when I can. Will this prevent me from connecting to other networks, should I get this resolved before I do anything further? I tried flashing a CSC-Multi from JVS and it did nothing - just reset all my apps. /system/csc still missing.
Thanks,
-pN
Nope. Csc is basically irrelevant. You'll need your phone unlocked to use another providers sim tho if your phone is branded. Look up the efs nvdata hex edit method for the best way to manually unlock your phone if you haven't already.

ok - thx. as for the unlock... here's a weird one. I did it using the 1-click unlocked and tested it with the two local providers (Rogers and Fido). that worked. I then took it to India and tried to put a vodafone / airtel sim - and it wouldn't even find mobile networks! flashed to another modem (JVS), didn't help.
poked around and I think the imei got trashed as it was showing the default junked imei. I restored the efs and re-unlocked, this time using the galaxy unlocked from the marketplace. curious to see if this was the reason why airtel/vodafone were rejecting my phone...
Well here is my very first post. After much research and study on this site, I have finally confused myself or my phone or both.
So I recently got my hands on my first Galaxy s GT-i9000, bought from a Ukraine guy here in NZ.
Everything works normally except i have no service anywhere i try. Thats how i got it cheap.
It came with VNZ 2.3.3 GB update and with the unknown IMEI problem.
After many attempts, I had managed to get the IMEI and baseband back.
I have since discovered that the original nv.data.bin file was setup for Israel network, Cellcom.
I have tried to flash it with Vodafone firmware again and all seems fine except for No Service. It says its on GPRS mode and the signal is -111dBm 1asu with no change at all.
I have then tried flashing to Cellcom rom that i finally found but it ends up with unknown IMEI AND baseband and I can't seem to get it loaded onto this firmware. But does it really matter what firmware/modem it uses, especially since the phone is in New Zealand.
I've checked and it says it is all unlocked, so it seems that way. But neither Samsung NZ or Vodafone can tell me the real lock status since the phone wasn't originally setup for NZ.
What to do? Anyone from NZ with an imported phone having this issue?
So anyone with this experience got some ideas?
I'm not 100% sure if this is relevant to your situation, but do you have a backup of your EFS?

I've made several backups. They seem to vary though because of the different roms I've flashed with odin.
Sometimes it changes product I'd depending on what regional firmware I try. For example at the moment its running on VNZ but the product I'd is showing up as I9000HKXCEL when it should be set for vodafone. I'm working out how I could change the EFS so that the default code is NZ.
Would it work by editing somehow the product code inside the nv_data.bak file? Would that ruin the IMEI? I have backups over backups if I were to test.
Hey,
NZer (quite an inexperienced one when it comes to Android but I'll try my best) here as well
Uhm. Check the back of the phone, behind the battery. I believe the IMEI of the phone should be written there. Look through your backups and see if any match.
Also, firmware doesn't matter. Think this phone was bought here, but I'm running a UK firmware on it (and previously a Korean one) and its fine.
That's about as much as I can help :/
Sent from my GT-I9000
Hey there thanks kiwi.
Its a weird one I have. I'm currently stuck on vodafone firmware because now when ever I change rom the imei goes away and backups seem to be gettin less reliable lol.
hmm I'm now wondering about what the correct permission and owner settings should be for the efs folder and files. Been using root explorer for most of my alterations.

Thanks for your advice pidio.
I must be doing something wrong.I've I've flashed from sams site and have tried both the latest VNZ 2.3.3 and the latest cellcom israel 2.3.3.
Only one that's working so far is Vnz but when I check with SGSToolbox, the product code is showing cellcom in both the nv_data.bak and data.bin.
It seems my imei or efs setup is "stuck" and won't give me a break through with essentially the "no service" issue.
Hardware wise, despite the bluetooth and WiFi working fine, although chewing the battery life badly and heating up quickly, can the GSM CDWMA part die out separately?
hmmm
Boy I'm so glad I never had this much trouble with the good ol' budget Huawei X5.
Hiya!
Hate to be a pest, i did use the search button, but to no avail!
I got a used i8190n that works perfectly fine in all aspects except for registering for a mobile network! and that is for calls and sms services only, as the mobile data, 2g and 3g both work well!
there are similar cases posted on the forum, but none that replicate my case exactly: i did try different roms, different sim cards, mobile data works but no calls or sms! total mistery!
any help would be greatly appreciated, thanks a bunch, cheers!
Found one...
BUMP!
Tried a few ROMs from different regions, none of them show any signs of improvement!
Funny enough, all of them display 'Not connected to network' message when trying to place a call, all the way until i started flashing different modems, and all of them started showing the dialling screen for a split second, and then display the 'call ended' screen, but that only happens with the XXALL3 modem!
any help would be greatly appreciated from here, any better modems out there?
Thanks!

Is your phone by chance sim carrier locked? Flashing the proper baseband and possibly modem should at least fix it on firmware/software level. Regarding the last mentioned; whats your region?

hi
the phone is carrier unlocked, as per the service menu, and according to the imei it's in the the UK region, i tried flashing Vodafone, EE, O2 UK roms and stock generic, even an asian one, just in case, no success!
upon reading some more, i looked into the efs folder (and made a copy of it), it's missing the nv_dat etc files, any idea if i can just get an efs folder off another phone and copy it in, or how would i go around all those files missing? i tried the 'NV rebuild' didn't help either!
thanks a million!

Its not advised to (fully) replace the efs partition (folder/files) with one from another device. The efs partition contains your IMEI, among other vital data, which is unique. Since you have a backup (make sure its a proper one or better few), you might try to replace the efs partition with one from another device (I8190N) to see if thats the cause of your problem (restoring backup if not). However, you have to change the IMEI manually after replacing the efs partition with the one thats initially assigned to the device.
great stuff, thanks!
btw, when i said i backed-up the efs folder, that's a 13kb efs folder, which is no good as far as i know
googling for an efs folder for i8190N brings me here first, and than here
and none of them really work for me, i tried the modemfs file, no luck.
any idea where i can find a good i8190N efs folder and, if the swap works, how can than edit my IMEI into it?
thanks!
And again...
dunno what am i doing wrong, got a i9100p Galaxy S2 off ebay again, and again, as soon as i plug my o2 sim card in it, same story! plenty of 3g but no voice/text service! went on and got the S2 totally stock and got a new sim card from o2, no luck! the mystery persists, any ideas at all would be greatly appreciated!!

yep, tried a EE card in it, no result. the new o2 sim didn't work either, so it's gotta be the phone!
goddammit!
I cant believe there is no solution to this problem. I can't believe the risks of rooting and customizing a phone may be so great... it *IS* possible to definitely brick a device after all...
So i suppose I am yet another guy who lost their phone playing with these #¤%"#¤% ROMs on XDA.
I'd like to know how your story ended.
Hi!
Resume:
My note has some weird problem with the modems. I'm getting "Unknown" baseband, modem verison, phone number, IMEI etc. with all the modems I tried except one, which shows the correct IMEI and modem version but still not working(I can even see the mobile networks with that one, but I it doesn't connect and gives me "Refresing SIM data" messages).

I always have been using custom roms(only TW) and updating my note to the latest version and I never had a problem.
One day, some months after the last rom update, started to lose the phone network conection and I was getting pop-ups with "Refreshing SIM data"(was very annoying because that was turning on the phone screen every few minutes). Sometimes I had phone network and sometimes I hadn't. The disconnections became more frequently. The phone also started to eat up the free space for apps, so I had to remove several apps to install or update even a small one.
So I decided to change to a different ROM to see if that fixes both problems, but I got the actual problem.
I was in AllianceRom v3 JB when that happened.
I flashed this AryaMod 5.5 JB following their instructions and I got this weird problem. In the "About phone" says that the Baseband version, IMEI, IMEI SV, Network and My phone number are "Unknown". I can't even search for mobile networks because it says "Insert SIM card" when I try to open the Mobile networks menu. Tehre are no signal bars, only a "denied" icon on the status bar.
I tested all JB modems and some from ICS from the "all modems" thread, but I was getting the same "Unknown" things in each one, except the XXLSO, where the Baseband version, IMEI and IMEI SV were okey. I could also find mobile networks with this modem, and the "Refreshing SIM data" thing returned, but it was not possible to connect to a network. With this one, there aresignal bars, but they are empty.
I flashed the AllianceRom and even the old ICS rom I had before, but the problem persisted, even with the modems they came with.
Now I'm on the latest Samsung rom(LT4), unmodified and flashed with odin and the problem persist.
I found this old thread. His initial problem is very similar to mine, but they don't know what caused it nor how to fix it.
I have also found something about corruped IMEIs that you can fix doing something with the ADB and restoring EFS folder, but I think that is not my case because I can see my original IMEI with the XXLSO modem (and I my EFS folder looks OK, anyway I have no backup of that).
I don't expect to get a step-by-step tutorial about how to fix this, but I hope somebody can put me in the right direction. I will post the solution if I find one!

I tried both. Also I have been using the SIM with another phone for weeks and works fine. Tried to take out the battery and wait few minutes and other "stupid" things like re-flash a ROM, re-wipe all, etc..
Maybe it's the programed obsolescence, you can use the Note as PDA but if you want a phone, go and buy another...

If it was a corrupted IMEI issue then it should not come back when the xxlso modem is flashed.. And also not sure why it goes to unknown when any other modem is used.. Could there be any physical damage to the sim tray? Dropped the phone?
I have no backup of efs... I had one "nandroid" but deleted it after everything was okey...
I could delete the efs folder, so this unknown problem will turn a known one :victory:
I dropped the phone a very few times, maybe in one of those something broke a little and has increased more with the usage? (the disconnections from the network became spontaneus and progressively).
I found this other thread, I could try the same but I can't find the original GB firmware, every link I find is in hotfile.
Check in Samsung-updates.com firmware section. There are 2 GB roms there..
I found a efs backup from may 2012, probably auto-created when first installed ICS.
I flashed the stock GB rom and restored it following this tutorial for my .tar.gz file, but didn't work, so the device may be lost. I only have 3 more backups: boot.img, data.ext4.tar and system.ext4.tar. I guess they are useless to fix this...
Thay you for you support!
