Hi everyone. I know this problem is well known, and Ive done hours and hours of search online and on XDA but none of the solutions worked or maybe i didnt do it right!
The problem, My friend have flashed a Custom frimware (Litning 6) and lost his IMEI and Baseband some how, they tell Unknown, and now he cant access his SIM or network, the phone doesnt really see the SIM at all.
Ive tried to use Chainfires APK to fix it didnt work, and the Hex stuff really made me dizzy out. didnt know how to use it really.
Ive tried to recover to EFS stuff but i think his EFS is trashed and he didnt back it up..
Tried flashing 2.3.3 stock rom and 2.3.4 no luck. still no baseband or IMEI..
Any suggestions? im out of luck and depressed
Why are you out of luck and depressed if its your friends phone?
If you dont know and understand how to recover these details I would say flash to a stock rom and take phone into a SSC and let them repair it for you.
Same thing happened to me, the phone eventually showed firmware emergency error so I just gave it to samsung service centre, they replaced the logic board etc and got it back 3 weeks later

ill look those links,,, but can i use someones EFS folder to fix this?
Ive checked the links. i think noth bin and .bak files are bad. cuz he already tried messin with them.. XD need new nv_data
you said that he LOST his IMEI.If thats true,and by using a root explorer with root access you can look inside the efs file or mark *#06# and see if nothing comes up,then without a backup theres no way you will get the original back without sending it away to the service centre(personal experience) but when it come back heres a good backup method.Easy as to backup and restore.

Basicly his SGS2 is not even capable of bring a paper weight cuz its too light (100g) lool.. what a bummer... ill try to find a shop to fix it with a box or something,, thanks all!
If you check your nvdata.bin and md5 you will see that, they modified the same day you lost your imei. So you have to return back to those baks and I don't think you can use another device's efs since your imei is hidden in that file.

new solution lounched Fix Repair unknown base banad I9100
Asansam ver 1.6.5 Released
-Fix Repair unknown base banad I9100
Note 1:
we add 3 Solution for this problem after you click Repair unknown baseband and select i9100,procedure start after finishing Solution 1 and phone restart check imei (with *#06#) if solution work you must see your phone imei if you see that you can cLick cancel and enjoy your revived phone if not click on continue and wait until solution 2 finished
do same like after solution 1 (*#06#) work on phone if you get good answer click cancel if not continue for starting last solution if it's not work too,believe me fellas check for hardware fault
Somehow this has happened to my phone, it is not even rooted, I flashed a newer firmware because I'm with bell mobility and they are still on 2.3.3, but that was over a month ago and just yesterday my phone stopped reading my sim card, and the IMEI and baseband are unknown.. I've tried a factory reset and to reflash the firmware, but it is still not working..
Now I cannot find the stock bell mobility firmware either to send it back..
has anyone figured out how to fix this problem? Or what could have caused it in my case?
looks like the service centre is the only option. Best to back up the EFS before tinkering with anything.
my GT-I9100 does this when I let it completely run out of battery power. I've only noticed it since flashing the ICS leaks but this may have been a problem before and I've not noticed.
When I plug the phone into the charger and start it up *#06# IMEI shows as unknown and *#1234# shows unknown modem, I have a small airplane mode symbol and occasionally, a no sim card error.
To fix this I have to let it take a charge for a while with the phone on - then reboot WITHOUT the charger cable plugged in. I probably have some kind of hardware fault but its not that important to me. I have an EFS backup, well I have a few backups here and there
happened to me a few days ago

Unless the hardware is broken you can always reflash the phone, even if 3 button download mode is not working.
Does the phone give you the option to search for networks? I had the problem you describe whenever I was going roaming and I would come off the flight safe mode. The phone would not connect to the network until I restarted it.

i don't understand you what do you mean by "Does the phone give you the option to search for networks?" but the wifi work perfect on my phone
if you type *#06# does the imei show ok? if not it could be a corrupt nvdata.bin file. If you delete nvdata.bin and nvdata.md5 file it will reload them from the nvdata.bak files but do this only as a last resort.
Edit: Back them up first mind.
I'd just reflash if I were you, you can use it as an opportunity to load a newer firmware if you're not already using a new one, JPM is working great for me. I'd advise using Titanium to backup your contacts, accounts, wifi access points, launcher layout, etc, etc, first though. You should be able to restore the entire look and feel of your phone then, not to mention all the app data, etc.

This very same thing happened to me as well. This is because your IMEI is gone or is invalid.
Networks detects your IMEI so when you don't have one, they won't give you permission to their signal.
I didn't backed up my EFS folder before this happened.
Luckily, SGS Toolbox did make a back-up of my nvdata.bin when I checked for my product code before I screwed up my IMEI and I just replaced the corrupted EFS folder files with whatever SGS toolbox backed up to fix the issue (whew!)
I don't think you can fix this on your own unless you backed up your EFS folder before having this issue.
Try to follow the other user's suggestiong to delete the two files and reboot ]but ENSURE that you back up your EFS folder. I suggest creating 2 back up files. 1 in your PC and 1 in your phone's SD.
Note: Flashing will not solve this. Since ODIN does not touch your IMEI. If its' invalid, it will stay invalid regardless of how many flash you make.

Hold on, a Galaxy S must be within it's warranty period, it's a recent product. If you have a faulty product, it's Samsung's responsibility to honour their parts warranty. I would have gone mad if Samsung had asked me for $300 for something that is their responsibility. Call them again and request a repair under warranty.

Is it a motherboard problem??
Hello to all. I'm trying to fix my friend's s4 i9505 because it shows that it's Baseband is Unknown and IMEI is null/null.
He told me the baseband and imei changed when he upgraded to 4.3 using wifi.
I have tried to flash stock rom but unfortunately the phone is in 4.3 so no downgrade.
I have tried flashing different modem.bin but still no avail.
He did not back up his EFS folder before upgrading to 4.3 but I still looked at the folder anyway.
I noticed that inside the EFS folder, there is no nv_data.bin and md5 file which is I think needed for the IMEI.
Is there a free way of recovering these files?
Is this a hardware failure?
I tried the different methods on recovering IMEI in the forums but all of them involves those 2 files so I can't continue.
I have another friend who has a i9500, can I copy and use his nv_data files? (He is willing to do it BTW to help my friend)
FYI: WIFI, Bluetooth and other functions are OK. It's just the call an text function which do not work.
Currently in JB 4.3 XXUEMJ5
No more warranty on the phone.
Any help would be greatly appreciated.
Thank you for taking the time to read our problem.

This phone isn't that old! I have only today contacted Samsung as there is nothing in my EFS folder, they are sending out a jiffy bag for me to send the phone to them to repair under warranty!
Be careful talking about swapping efs partitions from phone to phone as the mods in here get funny about it, I would try contacting Samsung to return it if you can? When did you get it?
I would suggest you do the same. I can't fix mine either.

Should I try this too? I've just seen on Samsung website that mobile phones are covered for 24 months. I've only had this 8 months.
It's weird I have imei number when I type *#06# but nothing in efs folder!
Sent from my GT-I9505 using xda app-developers app
Thanks for all the replies. I tried to check it with my local technicians and all of them told me that my main board needs to be replaced.
I didn't know that a software mishap can result to a hardware failure to the extent of changing the main board.
I have tried flashing the recommended modems above but unfortunately still does not work.
I have noticed that when I type *#1234# in the Phone app, It shows me the AP and CSC and that is all written in the screen. No word modem and no modem version.
When I try to flash a firmware or a modem it says it flashed successfully but when I check the phone, still no service.
Again, wifi, bluetooth and other phone functions are working.
Technicians told me it is a "no service" unit and "cannot be fixed by software" because I have a "broken baseband/modem".
Is there really no hope for this unit?
Again any help or info is welcome.
Thank you for reading friends.
Bump
What do you want anyone here to say if you've been told by someone qualified that it needs a motherboard replacement ? In some (many ?) countries, this would be fixable by 're-writing' the IMEI to the device (either by a Samsung service centre or other repairer), but if that's not possible for whatever reason in your country & the way they fix it is a motherboard replacement, you don't really have any other option, do you ?
Edit - Attempting to move EFS files between devices normally ends up in both being blacklisted. Not recommended.
Hello,
I have exactly the same problem, with the i9505 phone version, do i have to change the motherboard or it can be fixed the "soft way"?
Hi, i have a problem with my S4 gt-i9500, one day my device become to kitkat and then the imei number change to 049... so i pay for a repair, everything was fine after repair but when i change the rom to a custom one the phone said "no registered on network", i go back to the last stock rom but not solve the problem, i have the imei as back phone say, what can i do? Any idea? Thanks
Restore your efs folder.

Had the same problem like you before. You must have done something that altered the Baseband/Modem. I will assume you haven't made an EFS Backup. What you can do is this, download a stock Firmware and manually flash is. Just be sure that the firmware you will download is meant for your country. After flashing, try to see the IMEI of your phone. If the correct IMEI shows, then try making calls, text and connect to your mobile data. If not, then try flashing any modem meant for GT-i9500. If the problem still persist, then your last option would be to change baseband antennae or worst, replace the board itself which can only be done by technicians which has the proper replacement parts.
Thanks for answering, i flash my device with my country oficial stock room, after that im still having the correct imei but cant make calls, say no service and no registered on network, i have efs backup, but after restore nothing happend =(

Problem:Rooted the phone and due to some issues but somehow it became unrooted so I tried to root again but this time it failed during odin downloading mode halfway. so I unplug and was not able to boot up the phone. So i download and install the stock firmware from sammobile and manage to get the phone to startup . But the next issue is that the imei is gone and serial number's wrong with no network .
Did a bit of researched and I managed to write my own imei in through a thread I've found here . But my serial number is still different from what I've checked from the back of my phone and the network is still not up . I've check my ESN n MEID number is some random numbers or just 000000000 , tried to search for how to recover but to no avail.
I've tried doing imei repairs using GSII_repair and tried to follow some threads on things like deleting efs folders etc BUT I am not able to find the nv_data file even after rooting so decided to drop the method .
Do let me know what you guys need in order to troubleshoot the problem .
Did the phone's imei and serial # match the label before you rooted the first time?

Erm , I'm not sure about that thou . :crying:
Did you buy the phone new or used?
The easiest way to fix that, is to flash stock rom, but not just any ... it has to be the exact same region as the phone originated. Otherwise you get screwed EMEI, etc. Some countries the phone is carrier locked, so you also need to take that in account when getting stock rom. If you can't find those out... then it can be a problem. Maybe bring it into a samsung repair center to be checked out.

I flashed the stock rom from sammobile using odin , managed to get the phone up but thats when the imei and sn gets screwed up I think . I'm from singapore and our phones here are all unlocked . Used to work for 1 of the telcos here so I'm 100% sure it's not sim locked . I checked with my friends at samsung and they told me their process is to switch the motherboard and it's not worth the price, so I would want to try all the methods first before converting it as a expensive media player lol.
So the phone is originally from Singapore? Or you just flashed stock rom from Singapore? If the phone is originally from Singapore and you flashed a stock rom from Singapore, it should work... unless you tried changing the EMEI yourself. I think it's all messed up now, so you probably only have to take it to a shop that can do that for you. Changing motherboard from Samsung (or any manufacturer) is always super expensive. Hopefully you can find someone else with a small shop that can do it -- otherwise, I guess better to get something else (because price won't be worth it, as you say).
Good luck. Hope you sort it out.
PS, I like visiting Singapore sometimes... miss Brazil Churrascaria ^^.
A ling time ago, when I tried to downgrade from 7.1 to stock, I lost my imei. As I hadn't taken a restore file, I couldn't be able to save my phone.
I took it to several maintaners, but they all said in common that it wouldn't be passed an imei. So I lost all my hope. Even though I found a modem file and zipped it through twrp, I see an imei on my phone's settings screen, but my network never operates.
I don't know if I clearly told you my story but I hopefully hope you understood and will be able to help me reload my ex imei back.
Thanks beforehand.

The IMEI you see is likely invalid, especially if it doesn't match the one in the battery compartment. You need Samsung to fix your device since they can replace the IMEI.
