Hello everybody, some wweks ago i traded an iphone 5 for a samsung galaxy note 2, then i discovered that the phone is refurbished as on the back says a imei and model n7100 and in settings apper to be n7105 and a different imei. When i try to connect to internet, i always connect on edge, if i pick 2g only, it's Edge, 2g/3g/4g it's Edge, 3g only it's No service....What can I do? I flashed 3 different stock roms, i flashed cm 12.1 i tried anything, setting are right... Thanks in advance
I'm betting he changed the IMEI to a none 3g device or the face that the IMEI has been flagged. To be honest there is not much you can do short of sending it in to Samsung to be fixed.
Hello, i checked imei on a site and it says it is Model: GM203
Brand: G.M
and this brand doesn't exist...Can i rewrite the imei with nv tools? Or at a service can they repair it?

Well that could mean a few things. It could be a knock off device. Those normally have invalid IMEI (as in can't find a brand)
The only legal way is to send it to the oem. They will want to replace the main board which it would be cheaper to get a new phone.

Hi All,
I have accidentially bought Galaxy S3 GT-i9300 in China. Device came with Hong Kong 4.0.4 firmware. Unfortunatelly i could not fully test it because i didn`t have a micro-sim. It is international version called I9300GSMH.
I returned home, made a backup of EFS with EFS Pro and flashed 4.1.2 Poland into my new toy.
After that i immediately got several problems:
1) IMEI is OK and legal, but SN = 00000000000. That means no network and no phone calls. Fixed quickly with "special modem", but not sure if it was the best way.
Is it possible to repair SN if i know it? Does it make any sense by the way?
2) GPS is not working at all. GPS Tool doesn`t see any satellite. Neither GPS no Glonass.
Have no idea how to fix it and why this sh,,t happened.
3) Wi-Fi range = 30 cm. My router is Dlink DIR655. Other Samsung devices work with it up to 15 meters around. This one - 30cm. Tried to change settings, apply fix - no result. My S3 can see all wireless networks around, even located on the different floor of the building... but it can`t connect to any of them with "passwor wrong" message. Put it right on the router and problem disappers. WTF???
My S3 came from Hong Kong, but it doesn`t accept China/HK firmwares. Odin stops on flashing the modem stage. Actually, for some reason, it can`t flash China/HK modems. My S3 accepts any of european FW/Modem, but not chinese, where it actually came from.
Now some surgery. /EFS and /Factory folders are different (how could that be?) Files NV_data.bin and NV_data.md5 are different in those folders. Actually approx 300 bytes are different.
NV_data.bin and .NV_data.bak are totally different and they have different dates of creation.
That is it. Have no idea what to do with this phone. It works as a phone with the patched modem, but no WIFI, no GPS, etc.
I will appreciate any help on this case.
Thank you in advance.

Thanks, but it is already done. My S3 doesn`t work with GSM network without Ariza patch. "Special modem" i meant Ariza patch for modem. That is the only way i know to make SN=00000000000 device work with GSM.
Any ideas why i`m having GPS and Wi-Fi problems? May be HongKong phone has slightly different hardware which is not 100% compatible with European firmwares?
Sounds like a convincing looking fake or a store demo unit etc.
Nothing is going to help, if it was a workable fake your going to need the custom firmware, the criminals used originally to build it.
Can you post a screen shot of the system info and pics of the actual phone?
Personally I'd just take it to a mobile repair shop to get it looked at and to get a proper answer.

I don`t think it is fake because system information looks like genuine samsung except sn=00000000000. also i can upload samsung firmware to it and it works except GPS and Wi-Fi. Under the battery there is a label containing Model = GT-I9300, real IMEI and SN.
Another question is modem. Telephone came from HK or China. I can flash it with HK firmware to return it to original state, but modem remains XX - europe. When i flash only chinese modem Odin fails with "bootloader blocked modem update" or something like that.
Smells fake .

Why do you think it is fake? Fake phone has different firmware and not compatible with Samsung.
I have checked deviceinfo as well. It is genuine Samsung...
Can someone share deviceinfo from the International GT-i9300 ? I want to compare, may be some IC chips are different and i am simply using incompatible firmware...

Exactly same situation in Argentina.
I bought a SGS3 and after full charge battery and backup EFS I flash the Poland 4.1.2. After that i can´t connect to GSM network and my serial numer is 00000000000
Is not a fake. I bought from a recognized operator.
Then I flash an ICS 4.0.4 ARO (ARO = Samsung official roms for Argentina)
Now I looking for the Ariza solution, but I fear to have the same problems descripted here, cause I have the same facts.
So ¿Any questions to this post answers?
Thanks people, for that who live away from big cities is impossible go to a technical service.
Update. I`ve also got i9100 aka Galaxy S2. After official (no grey market, no sim-unlocks, no root, no odin, etc) update via Kies it shows same SN=00000000000, but everything is OK. GSM, 3G, WiFi, Bt, Gps - all parts work as they should work without any problems or applying any patches!!! That means problem is not in SN=00000000000. This zero SN is probably just a sign of the different problem.
same problem

No IMEI = return to seller possible stolen phone . Take to service centre .
Modem does not fix IMEI .
IMEI restore is only by restoring your backed up EFS folder .

If your phone has only empty/broken IMEI. You may send it to any service center. It is very easy to reprogram EFS and repair IMEI if you have original IMEI on the phone label.
In my case nothing worked but IMEI was correct and here is step by step instruction )
Step 1. Find working 2nd hand 9300 motherboard ($130 in my country).
Step 2. Replace motherboard.
Step 3. Ta-da.
After breaking my "/efs" folder (IMEI) though a dodgy flash, I began looking at how to flash a new one (well, what's written on the sticker under the battery).
Finding that there is software and hardware combinations that can achieve this, hope was looking up, especially as my month old Galaxy S3 is uninsured.
"Universalbox" is one of the devices I stumbled across that can changet your IMEI number back to what it originally was, amoungst other stuff such as unlocking, but you needed to buy the $250 device, the $2 UART cable (have them both shipped to the UK) THEN pay the micropayment inside the software to achieve this.
I wish I had that kinda money, but sadly, being unemployed and living on my own doesn't allow for new gadgets very often at all.
HOWEVER. I popped into a mobile phone repair (and unlocking) shop and notices hundreds of UART cables on hangers on the wall. So I enquired about it.
I was quoted £15 which I really can't argue with, obviously they asked if it was stolen and I just said that all I want is to have the IMEI number that is on the sticker reapplied. Not asking for anything illegal, just to fix the software fault.
I get paid on Wednesday, so I'll let you all know how it goes.
tl;dr, If your IMEI number is screwed, ask around the local unlock shops.

If your IMEI number isn't the same as the one on the box, or sticker behind the battery, I'm afraid you'll have to go into a phone repair shop and tell them you need the IMEI restoring. That's assuming, like me, you don't have a backup.
At first I got the "We can't do that, it's probably stolen", but after explaining that it's just corrupted and all I want is it reverting back to the one written on the back of the phone, there wasn't a problem.
I'll let you know if my problem gets fixed tomorrow.
To find out what the device's current IMEI number is, either:
Open up the "Phone" application and dial in *#06#
or
Settings -> About Device -> Status

Is there a Mac version perchance that works with the GT-I9300?
Hello everyone,
I have Samsung Galaxy S2 international GT-I9100. It fall into water. After that everything working fine excerpt IMEI null/null, Baseband Unknown, No SIM Card Detected. I exhibited it and dryed for a month. When I compiled it up again, same problem.
After that I decided to change the moatherboard. I bought new one, change it, turn phone on and same problem!! After that I install new ROM via Odin. And the problem still exist! How this is possible?? Oh and I want to mention that I can't access service mode. When I try to access it service mode is opened but menu is blank!
What you think the problem is?? Maybe smaller motherboard, because the small one at the bottom of the phone I didn't change. I am very desperate after so many tries so please help me.
Thanks a lot
anyone???

most probably your efs folder is corrupt or some hardware faulty. Do you have any sort of efs backup with you ?
If you have no backup, you're probably boned. Download as many stock roms as you can & start flashing. If that doesn't work, take it to a local mobile repair shop; many have equipment which can re-write the IMEI to the device fairly cheaply.
Thanks for answers, no I didn't make any backup for efs, so today I will start flashing all available ROMs for my country if this will not work I will take it to the service.

Have u tried restoring With Samsung Smart Switch
No i have not tried
Try restore it with Samsung switch, if not you'll have to find a way to change the imie no. Back to its original otherwise your network won't register the phone to you.
I got the same problem... I guess the IMEI has been altered or the update failed... i tried to downgrade to 5.1.1 but impossible. :/

I'm also having trouble. I bought my phone out of an independent shop, on purchase they told me it's not possible to update, and basically got the phone at a bargain. But, I have been doing digging. My guess is they have bought a blacklisted phone and flashed a cert to fix it. So my question is.. what is a cert? Does it contain the imei info, and is it tied to the software version the cert file? And will it ever be possible to flash a MM rom. I have tried and it won't go past the Samsung logo, only 5.1.1 Roms work :/
Hi, i have bought G977N and later came to know that its IMEI is tampered to get registered on the local networks. it was working before i upgraded it to G977NKOU4CTG1, the original firmware was G977NKSU2BSL7. After upgrading it did not register any of the networks. Got it checked from software expert he told me the network patching done with tempered imei was damaged and now there is no way to do it again on new version G977NKOU4CTG1. I tried to flash G977NKSU2BSL and also the factory firmware of android pie but ODIN get stuck at BOOT.img and download screen shows non-supported version. Can any one help to restore my original IMEI and will it work.
The IMEI ( read: International Mobile Equipment Identity ) is a unique numerical identifier ( 14-17 digits ) for every mobile device what helps to differentiate each device from one another. If you take your phone in for repair, they will track it using the IMEI to distinguish it from the other millions of phones, for example.
IMEI basically has nothing to do with phone's local network settings at all. But it may be used to unlock a phone on certain networks.
The IMEI is stored on phone's /EFS partition and/or /EFS folder. If you didn't backup that before flashing you have lost, IMO, unless you still have the box in which the phone was delivered, because there is usually the IMEI printed, too.
I don't have the box of the phone. The seller has tempered the imei to get it registered on the local network. I didn't backup before flashing. Now what to do. How to downgrade to previous firmware. I tried to flash the previous firmware but it stuck in boot.img.
They told me solution is available for U3 binary but no solution is available for U4 binary.
Awaiting for help on this issue.
You should have returned the device. Since the imei has been tampered with you will not get much help here. Imei changing and tampering is illegal in most countries. And it's not discussed on xda

I'm guessing you also bought a tampered IMEI device. Take it to any local market where there are plenty of phone 'software repair' guys. Ask them if they have Chimera or z3x tool. They'll fix your problem for ~800 PKR.
Remember, if you buy such devices, don't flash anything on them. Every time you do, you'll need to go back to the same software guy and pay him to fix your signal issue.
=========================
For other people reading this comment - Yes I understand IMEI tampering is illegal in most countries. The reason people in Pakistan buy these phones is because the government has levied unreasonable duties on all imported devices, without any consideration for the age/condition. For example, a used/refurbished S10 that costs you 250 USD in the US, will have custom charges of about 250 USD applied to it if you want it to work in Pakistan. So basically you pay double.
I have this same issue somtimes the signal comes and somtimes it doesnt.
