Hi, I am using Samsung Galaxy SL I9003 for couple of weeks. 2 days ago I found a problem that showed me "Insert sim card". I gave my set a master reset and then the set was ok. But I got the same problem today. I tried the same way. This time master reset is not working.
My IMEI is 354949040415515. PDA:I9003DXKB1, CSC:I9003OLBKB1. Firmware version:2.2.1, .
If someone knows about it. Please help me. I will be grate full to you.
I think you have problem with contacts of your sim card. Try to clean them. Also you can try to show your phone to the service. I don't think this is problem with your firmware.

First advice is never post your IMEI no. in public thread.
As IMEI is intact there should not be any network related issue due to non registration of your device at centre of your network service provider. I feel it could be hardware issue with the SIM card slot. But not necessarily hardware, it could be even problem with your SIM itself. If its used for longtime. first test with another SIM card, may be from a friend or a family member and make sure its not a sim problem. Then if you some how you think it could be related to Firmware you have DXKB2 FW available for flashing as single PDA file. You can upgrade by flashing it from the I9003 firmware thread of Krrazyy or from Samfirmware.com. If that does not solve your problem, take it to service centre for hardware repair. All the best.

Hey, I flashed with DXKB2 last night and my phone acted ok for couple of hours. Then the problem has started again. Another thing is, now it doesn't show my IMEI in setting option or after pressing *#06#......even after pressing *#1234#, it shows me the PDA and CSC, but it shows "Phone : Unknown". Is it a network related issue? If yes, wht to do now. Thanx for the previous comment.

Not network you wiped your phones IMEI with the flash .
You backed up your EFS folder then just restore it .
NO apart from why not you need to find the EFS restore thread that may help .

I mean electric contacts of your sim card. Try to clean them by alcohol. I'm not talking about sim records of phone numbers

Thanx buddy.......Another thing I want to inform you my phone shows "Baseband Version : Unknown". I showed it to the customer care and they said that the problem is with Baseband version. They also said that it's a software related issue. But my problem is it showed the IMEI and Baseband Version for 2 hours after my flashing. Then it started again. What type of flashing is going to help me?
Another thing, Can u please tell me or give me a link about restoring the EFS folder? I searched it in google.. but no result!
In addition I am using it from Bangladesh. As far as I know it is not officially launched here. Do I need any unlocking process? If yes, how can I do that??
N.B: Even kies is unable to connect my phone right now!!!!
I have the same problem
Hi, I have exactly the same problem on my Galaxy SL i9003. Did you finally manage to solve it?
to restore imei you need to have backup of your working imei efs folder.i see you have your imei number written here not sure if it is possible to mode efs folder to fit you phone.

It's been a long time. I was frustrated and stopped trying of repairing my phone. Now I see some light. Some people are talking about efs restore. I samsung captivate, a developer showed the way to repair imei and product code without even using pc.
Is it possible in I9003?
And hey, can u please tell me now whether I can mode my efs with that IMEI.
Please help.
this could be a hardware related issue also !
may be the pin where the sim card is inserted went inside or was bent..
or else insert any other sim card and see if ur phone works or not..
3rd this could be a corrupted sim card problem.. my sim card got corrupted and no matter in which handset i put my card in the phon won't boot ! btw it was a BSNL sim card..

If you made a backup of your efs folder, then via CWM it is possible to restore it. If such a backup does not exists, then things are really complicated. maybe you can use the backup of some other EFS from a different i9003, and try to modify the IMEI with yours that can be taken from outside the box. I don't know if you can do the last procedure but some expert maybe can!
Good luck.
I had a similar issue with another phone and sim card, similar to the contact issue. why not take out your sim and put it on a flat surface to see if it's still flat as it should be? if it got hot and became slightly warped, you'll have to bend it back (CAREFULLY!!!) so that the contacts are in contact again
if this is the case, you have to get a new one at your service provider so it doesn't keep happening...
Moved to General section since it has nothing to do with development.
Unless it does and I somehow missed it, if so just pm me and I'll move it back.
And see if u inserted sim card d wrong way.. It happened to me..
Sent from my GT-I9003
I got this problem too.
It suddenly happened to me when using stock room (xxkb1, if i'm not wrong), and in that time i never flashed anything in the phone, so probably not a software issue.
I tried rebooting billion times, put another sim card, cleaning the contacts, factory resets, prayers and nothing worked. But the weird fact is that sometimes it starts working out of nowhere for 2 or 3 hours and then it stops. It confuses me, because it means it's not hardware too. So then i tried updating to xxkpe and xxkph and the problem still remains.
My sim card is not bent, its not inserted in wrong way, the sim cards work in others phones, shows "Insert sim card" when i try going into network settings, doesn't show my IMEI in setting option or after pressing *#06#......even after pressing *#1234#, it shows me the PDA and CSC, but it shows "Phone : Unknown" (like OP), and i didn't backup the EFS. Everything else in the phone works great..
Could you guys help me out? I live in small city in Brazil and bought the i9003 in Paraguay, there are no samsung customer care or similar nearby.
First post, long time lurker, so i'll start with a big thanks to the entire community for all the help you've unknowingly given me.
I just got a nexus 5 to replace my original n5 which has a broken screen. I took a backup of the original and restored it to the new one. Unfortunately i didn't know what EFS was, so i restored the old EFS to the new phone. IMEI went to zero. HUGE BUMMER.
I was able to fix the IMEI with QPST, but the new phone will not connect to the network. I've run a check on the IMEI and it is not blacklisted. Without incriminating myself, lets just say that i'm positive that the new IMEI is good.
The phone recognizes that i've inserted a SIM but shows no signal. I've tried to search for networks, i've checked the APN settings...
I REALLY don't want to send this to LG since they can't give me a price or even a ballpark figure without me shipping them the phone...
Any advice on next steps would be greatly appreciated.
What should i try next?!
flash the factory img and do not restore your efs on it.

I guess i should have mentioned that i've flashed factory also. Currently the phone is on the latest firmware, unrooted, locked bootloader. Flashing factory had no effect at any point.
I bought this phone on Swappa BTW, so i am assuming there are no hardware issues. I'm not at all certain what else may have been screwed up by having another phone's EFS restored over this "new" phone's EFS...
More Info
I am able to attempt to manually select the network. When i search for networks, the available networks are shown, but when i try to connect it shows the Registering dialog for quite a while, then fails. This is the same behavior as a working phone without a SIM installed. The odd part is that the phone will recognize when a SIM is installed or removed. It seems that my problem may be that the SIM is not being read properly or the data is being lost/corrupted between SIM and antenna. Is this possible? Is this EFS corruption? is this something i can fix? Please help.
Bump?
Hey all,
I had an S7 edge (G935F) since launch. I took a full backup of it with TWRP (EFS included) then had it replaced with an identical phone (G935F). I stupidly restored the backup including the EFS from the first phone. This is now causing my new phone to not register on my mobile network, and to say "unknown" for IMEI and bootloader.
I do know what the IMEI is supposed to be for this new phone, but I don't know of any way to set it. I also never took a backup of the new phone so I have no way of recovering its EFS.
Any help appreciated.

Good morning everyone..
I have a note 10.1 n8000... it was rooted with cm12.1 and everything works fine...after a year i decide to change my rom to stock...so i flashed the official stock rom over odin.everything works fine except the service...i dont have signal on my tablet.i am serching for about 3 days and i found that is an imei problem...my imei changed to 004999010640000/01 which is a generic imei as i read...i tried some possible fixes but nothing changed... how can i solve my problem? How can i restore my imei back to normal??i called samsung service and they told me that i need a new motherboard to fix the problem.i dont think so...
My tablet isnt rooted right now... i need a non rooted solution first but if it isnt possible i will root my tablet again..
Thanks for your time...
Restore your backed up EFS folder see multiple identical posts ( failed to backup
take it to a service centre for a fix).
I don't have the efs backup... is it possible if I root my device? I saw many videos that change imei if the device is rooted.. even apps on google play store.. can these apps make it work?
Maybe another way with rooting?
No point rooting it cannot help.Service centre next step.

Hello there, I got a Pixel 3 from one of my friends recently, after some days i reset the phone and suddenly SIM stopped working, when i checked the IMEI no. of my phone it was "004001520220002" this. But my original IMEI before reset was 99001200********. Now i had no idea what just happened with the IMEI. that new IMEI is blacklisted & hence i cant use the network on this, so i tried to recover my IMEI by using root method. After messing around with my device for a couple of days, i was successfully able to root the device and install Xposed Framework in order to change the IMEI no. I have changed my IMEI no back to its original but network is still no where to be seen in my phone. *#06# will tell me the old good IMEI but i am still unable to get signals on my phone. What should i do now ????? I am not an expert with the ROMs or modifying the OS. PLZZ HELP ME GETTING MY PHONE SIGNALS BAKC PLZZZZZ
How did you able to recover your imei, i'm going through the same thing, please share your procedure bro.
