[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] Nexus 5 Possible EFS issue, IMEI already repaired

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?

[Q] IMEI corrrupted

Bought a new S6 from Ebay that had been opened up to all networks. Discovered it was rooted which I didn't want so I flashed it with a stock Vodafone ROM. The phone worked fine for about 10 days then all of a sudden I got the message 'not registered on network' when I try to make call. It turns out that the IMEI number has changed. Does anyone know whether this type of problem can be sorted out?

Flash back to stock via odin.

IMEI Corrupted
I'm going to use a Vodafone ROM as this phone was originally on Vodafone before the seller had it opened up to all networks. THE ROM is G920FXXU1AOCZ_G920FVFG1AOC4_G920FXXU1AOCW_HOME.tar.md5. Does this sound like the right one? Sorry for all the questions - I'm new to this. The other thing worth mentioning is the IMEI at the moment is 350000000000006. Where could this have come from? Any ideas? It's weird because the original IMEI was in tact for about 10 days before it changed to the one above. Any help at all would be appreciated

Corrupt imei is known issue when flashing and rooted. That's why firdt thing you do when rooting, is you backup your stock rom together with efs folder. Idk which is your stock rom, you have to do some research, download that rom and use odin to go back to stock. You will lose everything you got on the phone btw so save any pictures or music.

Thanks for that. The problem I have is that there's no backup of the EFS folder or the stock ROM. Without these, is there any way of sorting this out or is the phone dead? Cheers

hi
i have same problem did you fix that if yes please help me

Bring S6 back to Samsung for repair

My guess is the phone you bought was stolen and after 10 days it got blacklisted.
Or the seller claimed he lost his phone to insurance company, sold it you, got a new one on insurance, and then after the 10 days the "lost" phone (your phone) got blacklisted.

Oh right, that's weird then! I guess efs partition could have just randomly corrupted.

I have the exact same problem, bro. All of the sudden my IMEI changed to 350000000000006 and I'm not able to register on my network. Did you manage to fix this? Please, let me know.

The same story, any help?

How I can fix this? Please help

Get Chimera tool and you should be able to fix it no problem

Did you manage to fix?
My baseband shows as attached after installing vador rom so I'm confused

If you didn't formatted/wipe the efs/nvbackup, there's a chance you can retrieve your imei.
But if it doesn't, the only way is to bring it up to Samsung or a good phone technicians to repair or get you a new branded IMEI for your phone. Mine was fixed by a technician using Octopus box tool.
You may try my method, http://forum.xda-developers.com/showpost.php?p=63693480&postcount=28

Network not available at recently 4.4.2 flashed N8000

Hi guys. I'm posting here in a desperate attempt to solve my problem.
A year ago I purchased an used N8000 with Omega 4.1.2 ROM installed, and worked very good. But a couple of days ago, I flashed my tablet to get the 4.4.2 update, because I need some apps not compatible on old versions.
Everything is ok except for the fact that my sim card is not recognized anymore, if I select the operator manually, I get a "network not available" error.
I made a lot of research, with no results so far to fix the problem. The only thing I learned is that I think it has something to do with the baseband version. Currently I have the N8000XXUDND2 version, the IMEI is ok.
I live in Paraguay, the 3G band of my operator is on 850MHz.
If there's no solution, can I just downgrade to the omega rom by flashing as usual? Or the process is different?
Thanks in advance

Tried flashing the modem I had before, still no signal. I think I screwed my tablet.

when u flash a rom then downgrade it the phone's imei code gets changed which causes "no network" error .
I'm trying to figure out restoration process of original imei code for my device too.

I don't even know how can I check the original imei of my device, since I forgot to write it down. On phones they are usually printed behind the battery, but this doesn't have a detachable battery.

If your IMEI is wrong then restore your backed up EFS folder .

It's written at the bottom back of the tab & on the box seal as well. Or dial *#06#. I tired hard reset & stock rom still imei error

I checked and indeed there's the original imei written at the back of the tab, and it's not the same number as of dialing *#06#. Don't know how to restore though since I didn't back up any efs folder.

You can do a search on XDA there are a number of posts regarding users that failed to backup EFS and null IMEI .

I have the same error, after root, imei and baseband are gone.
don't have efs backup

No 4G only 3g with 44s Modem. No other Modem works . IMEI and Baseband still there.

Hey I really appreciate any help that you can provide. I will tell the long story. My phone got corrupted while flashing different custom ROMs. Oxygen was the culprit. It completely damaged all the partition of my phone. So I repaired via 9008 modem loader using COLOR OS flash tool. then I found there is no baseband and IMEI. EFS partition damaged and I didnt have a backup. Damn it!!!!! Tons of research and googling I found how to use QPST tool by Qualcomm. I retrieved QCN file from friends ONEPLUS ONE (16gigs) and flashed it to my phone (64gigs) and edited the IMEI to my one. Rebooted the phone. tada. I got wifi bluetooth everything running. Phone signal just connects and drops every sec. It wont stay connected. but it is detected. then I thought it might modem issue. I tried every single modem out there but no luck. Finally flashed CM11s 44S Modem. Kaboom. Got the network running. but sadly it will only connect to 3g. I cant connect to 4g. No Other modem works.
1. Only get 3g service via 44s modem on any vanilla rom.
2. No other modem works.
3. Proximity sensor acts really weird. If a call comes Then I have to restart my phone to get the screen lit back. Fixed by flashing proximity fix
4. Baseband is always unknown with 44s Modem but has 3g network connectivity.
5. Other modem shows baseband but no connection even though it is detected.
Please help me guys.. What am I missing. any help appreciated.

1- Check If you have IMEI and IMEI sv and it's the IMEI that shows on box.
2- if no. 1 is true then check another sim card another operator ( to be sure that carrier is not blocking your IMEI for some reason).
3- if other operator's sim worked contact your carrier to check problem with them.

Hey thanks for the reply. I do have my IMEI from the box. I flashed QCN file using QPST tool and applied my IMEI but the thing is I only get 3g. 4G is not detected. Im not sure if something has to do with baseband files. But my friend is from my place and he gets 4g just not me. If I use any other modem other than 44s Modem the network will be detected but won't connect so i cant make or receive calls or anything related to service provide.. Do you know what to do ?

Okay let's make some tweaks :
1- backup modemst1 and modemst2 using dd (I don't trust qcn backup ) and copy them to your computer I also prefer to backup persist and fsg
2- download NEVER_SETTLE from https://forum.xda-developers.com/oneplus-one/help/fix-brickloop-audio-fx-fc-efs-corrupt-t2879061 (you will find commands to backup mdemst1 and modemst2)
3- flash only persist using fastboot and reboot to system and check everything again.
other partitions locations :
/dev/block/mmcblk0p18 (fsg)
/dev/block/mmcblk0p15 (persist)

IDK what i did my opo was dead for around 3 months, the screen was responsive but totally black. then managed to recover from it then bricked it.
just figured it out. I am on my own build of XOSP[maybe it had problem idk] but had to flash my efs[64gig] backups and got my original imei back [earlier i had restored to a different imei qcn file may be it belonged to a 16gig opo] and also got 4g signal but still no baseband.
Then flashed COS13.1.2 and got baseband back, now the proximity is also working as it should and also got LTE working and instant signal on restarting the device. Now again back on XOSP everything works. If you need i can pm the efs files.

FYI your IMEI will be lost if you do so.
So I suggest to backup your partitions first in case of everything goes wrong.
Any way I have qualcomm stock efs partitions with 0 IMEI in case if you need them

IMEI is encrypted so if you do so, you will see it in settings but network carrier will receive it 0. This means that you won't get 4g also only 3g. So I personally prefer that you flash efs of [MENTION=bablu084;70545585]bablu084[/MENTION] this gonna work except you're two in the same country.
