[Q] [q] after unlocking sim card...no one accepted

HI GUYS...
I UNLOCKED MY SAMSUNG GALAXY INFUSE AS USUAL, AND ITS OK "UNLOCKED"...
BUT WHEN I INSERT MY SIM CARD IT WORKED FOR FEW MINUTES, AFTER THAT IT SAYS NO SERVICE AND THERE IS NO SIGNAL AT ALL... BUT SOMETIME I GOT SIGNALS BUT WITHOUT REGISTERED NETWORK.
NOTE:
MABY THE PROBLEM FROM THE IMEI NUMBER, BECAUSE I GOT IT WRONG , IT IS LIKE IN THE ATTACHMENT.
PLEASE GUYS HELP ME ....

Yep, a borked imei number will not allow you to connect to your cellular network...
I'm guessing that your efs folder wasn't backed up... you can try this...http://forum.xda-developers.com/showthread.php?t=881162
I haven't tried this but good luck.

thank you brassguy...
but does this work for infuse 4G ?
In addition, I read that we can change the IMEI number using the ADB, or is there another way to do this?
Also, what about the GSII_repair app, can I use it for my phone (infuse 4G)?

i had this problem last night where i flashed a rom. i return it to stock and imei showed up.
was having a imei" unknown error" and i backed up now on my computer.
ps ebay sales unlock service for 0.99$ if you didn't buy the code and just hacked it with hex or whatever
mine is already unlocked and it's permanent
i do travel over seas alot

But i returned mine to stock many times but the imei number still like this.
I did no get you in the third line???

[Q] **Not Registered On Network, Galaxy s3 GT-I9300. Help!!

Hi all,
looking for some solid advice on what to do next, My Gt-I9300 is originally from ireland, on the network meteor.
i got it factory unlocked, then i moved to western australia , started using a telstra sim everything worked fine, then when i tried to make a call it would make no sound during call on both phones, (mine and the one im calling) when i hang up i would loose signal and then it would come back after a few seconds, so after doing factory restets ect, nothing worked. i then rooted the phone using odin to see if anything would change with the no sound during calll problem , the rooted file i used was for the telstra network (australia) then when trying to make calls it says not registered on network, went into network settings and manually tried to select the telstra network , still no luck. and now to where im at now , i unrooted my phone using odin the unroot file i downloaded was for the meteor network(ireland) one the phone originally came on . still the same problem with not registered on network. i will admit im familiar with what im doing but not a expert , please help i need my phone :crying:

can someone please help any advice will be appreciated :good:

Hi
First you have to root again, install busybox then install Ariza Patch for IMEI, click on patch 0.5 and you should be fine. I think everyone who has upgraded to leaked JB 4.2.2 ended up in the same situation.

I was having a similar issue on my friend's i9300. I upgraded his phone to 4.3 but got this issue. Unfortunately, I didn't back up his EFS so lost the network after upgrade (NOT REGISTERED ON NETWORK).
I Tried everything from Ariza patch to going back to 4.1 MG4 firmware & zuluman patching the MG4 modem but nothing worked at all.
I was at my wit's end when as a last resort I installed I9300XXUGNB6 firmware through Odin. Then rooted it, installed CWM recovery. After that I installed "Patched_Modem_I9300XXEMG4" zip through CWM (ATTACHED).
There was still no network & IMEI turned to 000000000.
After that I downloaded Boeffla 5.1 kernel (for i9300) and VOILA, I got network & IMEI was restored. I do not know how it worked but it solved my problem. You can download Boeffla kernel from his website boeffla-kernel. de
I promised myself to always backup EFS & never to upgrade anyone's phone again except my own. Too much liability.
I hope it works for you.

[Completed] Have signal but not registered on network

I have Samsung Galaxy S3 GT-I9300. When the google drive app was downloading from google play, my phone went off due to poor battery. Later when I tried to turn it ON, it has been getting stuck in the boot. So I decided to reinstall my custom ROM. Being busy with my baby, toddler, household chores and job, I gave it to my brother to flash the ROM. After a while, I noticed that my sim was bricked.
It says "Emergency Calls Only", has fake IMEI but working signal.
We did not backup the efs. I tried searching all the methods like modem installation, CSC, baseband verions, IMEI re-write, Kies Upgrade and Initialization, other people's efs restore, etc. But the problem is unchanged. Some of the followed method might have failed for not having proper knowledge like IMEI re-write tool works on specified chipset, etc.
What we noticed is that using different baseband version toggles from having network signal or no signal.
Kies shows more than four firmware versions and no other details like CSC, etc.
How do I clean up all these especially to have SIM working on my phone?
I appreciate you assistance to be brief and clear to understand steps than sending links. Because my time is stress-fully short.

Hi !
There is some confusing info in your post
What do you mean with it has fake IMEI " ? Have you changed it ?
You say that you have a working SIM on certain basebands , is this happening on a custom rom or stock ?
Have you tried to flash a stock firmware as I see that you tried to flash "your custom rom " ?
Cheers !

First of all, thank you for your response and interest to assist.
My mobile's IMEI is shown as 004999010640000 which is not original. Can you help me to change it to correct IMEI suitable for my Samsung S3 GT-i9300 chipset, if that helps in enabling sim to connect to a network? I think changing method only masks the IMEI?
I have tried flashing stock firmware and also Kies Upgrade and Initialization.
I have also changed baseband version installation on stock ROM too. I don't know which baseband is correct to keep.. for my country India or in the country where my mobile is manufactured, incase that's locking sim accessibility? Some baseband bought signal and detected the network operator name, but the message still says "Emergency Calls Only" and is unable to connect to a network.
I presume this problem arose when installing custom ROM from TWRP recovery and it messed up with efs partition?
I had successfully flashed custom ROM many times before without this problem. I think there's some next step to follow to bring back the working sim like I heard of installing modem. I did just try installing modem but same problem as my baseband is already bringing signal.
I had tested my phone from sim unlock app and found out that CSC is locked and it limited specified MCC and MNC numbers. Is this hindering connection to Indian mobile network? Or corrupt efs? Or missed to manually install something?

Bump.

[Completed] Help!! Galaxy J100H not registered on network.

Greetings, sharing here my particular problem from top to bottom just to take advice in general.
First of all, I live in Cuba, so my one and only network is Cubacel which runs GSM 900 mhz, so far so good with most phones.
I am between phones so I boorrowed this used J100h from a friend, which received it as a gift and has never been used. I performed a hard reset to wipe password, data, etc. Phone boots ok but no calls with cuban SIM.
The curious thing is that it does recognizes Cubacel network, it evens shows the changes on signal intensity. Bu when I try to manually add it, it finds and displays the network by its name, but reports an error when trying to register.
After 3 days of internet search I´ve narrowed to the following: I suspect the phone was unlocked or flashed previously, there is no network promo when turning on the phone but there is chinese rooting software installed and the cell is, or seems via root checker, rooted. Thought an extra /01 after the IMEI was a sign of corruption until I leraned about IMEI SV. Anyway, following this thought installed busybox and root explorer, checked efs folder, finding subfolders such as imei, factory app, etc, BUT NO .NV file. inside imei folder ther is a imeino1 file with the correct imei, but no .nv file outside. Is this fixable?? GSII repair doesnt work because seems theres is an error with the busy box install, what gives me doubts if the phone is really rooted, and if i need to be online to install busybox properly.
So, If I decide to try and flash stock rom and see if this fixes the problem here is my main doubt, which may seem obvious for some but i simply can figure out. Which stock rom version do I choose? the product code of the cell is ITV, and the bootloader also points to the italian version but the currently installed rom ends in AOG2, seemingly a greek version. I live in Cuba and everywhere I look people say that since the telephone is sim free you can install any rom, but the is no "any" or standard rom either in samsung firware o sammobile. Do I flash the same rom? do I flash the one matching the bootloader? Which stock rom version should I choose?
Very much appreciated if you have gone so far in this reading and have some piece of advice. Also excuse terrible English.

Hi !
I see plenty of firmwares on samsung website so pick one and see how it works , it doesn`t matter the region , you won`t damage anything , maybe the modifications that has been made on the device borked the network , clean stock firmware flash may resurrect it and try the one which matches the bootloader
