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 .
Try the Chinese thread .

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.

I got my samsung galaxy s2 this month. Everything is ok until the day before yesterday. When I try to make a call, it says "mobile network not available". I go to the setting--->wireless and network--->mobile networks--->select/unselect use packet data, there is no icon indicator it is activate as it should be. I tried the factory data reset, but the problem is still unsolved. Thus far, call/message stop working. Wifi is OK. Do you have any suggestion on that? Thanks.
Please check your IMEI, and your Baseband version.
If they are not available, you will need to restore your EFS, if you do not have a backup, you will have to visit Samsung Service Center, or repair the EFS yourself.
Do not use another phone's copy of EFS as it is illegal to modify or clone your IMEI number in most (if not all) countries. You can however use someone's EFS backup, and mod it with your phone's IMEI if you know how to.
Hi,
I'm in this horrible situation: no baseband, no IMEI. By ny chance, do you know how to get a EFS backup and change to my IMEI?
I appreciate any help. I was trying to make a call, the person on the other side could not hear me. I reboot and...lost my baseband. Checked IMEI, it was also missing.
Thanks

have u solved your problem? I got something quite similar...
In my sad experience, your only chance is going to Samsung and ask them to restore your IMEI. From what Samsung in BRazil told me, it should be in the same country of the device. As my device was imported from the UK, Samsung Brazil could not do anything, as IMEI database is Country restricted. I believe this info is correct as the representative was very helpful. It did not look like a lame excuse. If your device is not under warranty, it should not cost you more than U$ 50. That was the price here, and everything in Brazil is so expensive these days.
My solution was to buy another Galaxy S II in Brazil as it had been released here in between the time I imported mine and the time it got screwed.
Wish you good luck.

Just nt getting wt 2 do
I have the same problem, but if I take out the sim and put in another phone, it works, and if I took another sim (from another operator) and put it in sgs2, it also works, just this sim not working in this sgs2. Is this operator controlled by apple and trying to block sgs2 devices?

Any ideas?
Thanks
I've got the same problem...
does anyone have came up with a good solution?
Try this
Root your phone.
Go to efs folder in root. Go to imei folder in that you will find a file named mps_code. Edit it using root browser from market. Erase everything and type your original imei no. and save it.
Reboot your phone and now check.
Cannot guarantee it but it worked on mine. Good luck
Sent from my GT-I9100 using XDA premium
All I had to do to go to the Access Point Name ('APN') settings and change the Authentication Type from its default 'Not Set' to 'None'. After that, my internet is working fine.
It would appear this may be an issue common to a number of Chinese phones, so hopefully this will be of use to other people in the same situation.
hi there!
Ive read all I could and despite coming across several similar problems, haven't found an answer (so if anyone has an idea, plz help!)
I'll try to be as concise as possible:
I have a message that says: not registered on network
I have a China Unicom galaxy S3 (international model, gt-i9300) not copy, original version, bought from service provider store, running forever on android 4.0.4 (no updates available, via kies, or software update whatsoever)
As you know, because it was bought in China, it's blocked from factory settings (no svoice, google play, among others and of course a reduced overall functionality and an alarmingly high used of RAM despite of every app being closed) and even you can download most apps, they're in Chinese and they're different and not completely working versions of them (i.e. fb, skype,...)
Read and read, until managed to do rooting via heimdall (only have mac available), once installed SU, managed to download and install google play, but it kept on crashing, along a previously (VPN only) functioning fb app, and twitter.
After a while of more research I came across odin mobile, and by downloading an international ROM from Hong Kong via Sammobile, managed to install 4.1.2 from HK (I9300OZSEMC1). Despite the now no restriction phone i had, i came across a problem: cannot call or message or use mobile data, only with a message that says " not registered on network"
I did check the sim card, and selected the network manually, without success.
I checked the AP, CP and CSC and they were unknown.
After much frustration i remember i had a backup if the original carrier, and after re-rooting, managed to get back to the super blocked version of it, bu t the problem remained: not registered on network.
I checked again the ap, cs and csc and now are back to factory default (just like they were before all this odyssey began).
I changed the sim card to my gf's iphone and it works there, just not on the galaxy....
I repeated the above two times more, using roms from HK, Taiwan and UK..... same problem, even when going back.
Any ideas? I'm quite desperate now
thanks!!!
Is your IMEI the same as under the battery .
If not restore your backed up EFS folder.
No backup = service centre .
Do you have the correct modem and CSC for your network .

yes, imei is the same
before doing all the process, i verified and saved screen captures of how it was before and after, both pictures coincide, but still nothing...
(what is EFS folder? , i've done this with little knowledge on the topic, so i've no idea what's that ^^"
I guess service centre might help, but well, since this is China... i expect the worst.

I'm assuming you may have changed the modem during the flashing of the HK fw, try finding a Chinese Modem and flashing that. TBH this is why people tell you to read and read again before rooting and flashing custom roms.
hi guys i bought an samsung galaxy s II I9100 not new but still in a good status and he is runing very good when i bought it he had the an stock android 4.0.4 informations in attachement when i want to update to the 4.1.2 version he says that this is the last update for the phone so i downlaoded an 4.1.2 firmware from samfirmware i update via odin without problems but when i verify the IMEI isn't the same at the back of the phone and another thing on the back of the phone there is NFC under the camera but can't find't in options :crying:
No Help
1) I9100 = no NFC. If that phone has NFC capabilities, it's not an I9100. It will more than likely be an I9100P.
2) If the IMEI (in phone settings) has changed to '0049...' (Do not post your actual IMEI here), you might be in a bit of trouble. If the phone is an I9100P, download I9100P firmware from Samfirmware & flash that; hopefully the IMEI will come back. If the IMEI doesn't return, flash another firmware, and another and so on.
If it is an I9100 & you're merely confused about the NFC thing, download a bunch of I9100 firmwares & flash.
If after flashing a bunch of firmwares you still have the generic IMEI, try one/more of the many 'guides' on here which claim to be able to recover your IMEI without an EFS backup (no idea if any of them work or not).
If you still can't get your IMEI back, take it to a local mobile repair shop; many have equipment which can write the IMEI back to the device fairly cheaply.
Edit - Use a descriptive thread title in future - 'Help me please' is more than likely the reason you've been sitting for 18 hrs waiting for help, many people won't even look at your thread without a title which gives some idea of whatever problem you're facing/question you have.

thanks for your help what if my phone is i9100 and i have flashed an i9100p firmware what problems i'll have?
Probably none. The firmware is identical except for the NFC bits, as the I9100 doesn't have the hardware, that part of the firmware doesn't do anything. Given the rom will likely be for a completely different carrier, the modem in the rom might not be ideal for your particular carrier, and you might have connectivity issues, or you might not. But that's moot given you have the generic IMEI, you should have pretty much zero connectivity anyway (you'll be able to see the network but not use it).
Hi Guys,
2 months ago I bought a Samsung s5 in Hong Kong.
While travelling through South East Asia this device worked fine.
While traveling through New Zealand (Old home) this phone worked fine.
While traveling through America (New Home) this phone worked fine for the first 2 weeks (on the metroPCS network).
The problem:
Randomly after 2 weeks the s5 stopped connecting to the metroPCS mobile network even though the network was available (btw metroPCS uses the T-Mobile network). It gives errors such as network not available or cannot register with network.
Things I have tried:
-Im sure the APN settings of the phone have not changed and I have double checked to see if they are correct.
-replacing the sim card with another does not fix the issue
-soft and hard reset of the phone does not fix the issue
-Getting metroPCS to refresh the service on this number does not fix the issue
Other important info:
-This phone was purchased in hong kong but it is from the Philippians according to Kies's firmware information (XTC is the country code)
-It is running a custom allianceROM that must have been installed by someone in hongkong
-The device is rooted (superuser app installed)
-the model number as shown in settings is g900f BUT when attempting to flash with odin the phone displays g900t and fails to flash the latest Philippians verison of kit-kat
I have 2 questions:
1. Any ideas why my network connection has suddenly self destructed (and how to fix)?
2. Would flashing a stock ROM to my s5 help? and if so why is there conflicting information on which model I own (g900t/g900f)?
Please help. I do have some know how on flashing android devices but i've really hit the wall on this one guys!
Cheers,
Yetti.:cyclops:
It's not uncommon for the model # to be different with a custom rom as that is a very easy thing to edit in the build.prop. It should tell you under the battery which one it is. As far as the network issues, check to see if the baseband and IMEI are still there and not listed as unknown or incorrectly. It's possible you could get away with flashing the appropriate modem that matches with your update and that might work better in this region vs the previous one.
Please list the Alliance rom version and baseband version here in case it's relevant to your issue.
More info
Im not sure if this helps but looking through the build.prop file in the system folder my ro.product.local.region=GB
When in recovery mode the region is set to XTC (Philippians) using mutli-csc.
Also my IMEI number seems ok and is NOT blocked.
Cheers. Yetti :cyclops:
Baseband and rom etc
Thankls for your reply!
Sorry when you say "under the battery symbol" do you mean in /odins boot script on the device/ or /in settings on the phone/?
Baseband is g900TUVU1ANCH
Build Num: AllianceROM_G900F_XXU1ANCF
If the "no network" issue can be solved with the current firmware that would be the most desirable solution but going through the flashing process may be a good idea for my learning process, and will help with future updates.
Do you think getting back to a stock rom would help me?
tHANKS AGAIN!:cyclops:
Model confirmed to be g900t
Sorry i didn't understand the "under the battery" thing. I was lost in software world. The sticker under the physical battery says SM-900T so i guess that confirms that it is a t-moble verison (and the baseband is therefore correct).
I will try to flash the T-Mobile stock image to the phone and see if that works.
Also i will try to flash a modem (after i work out which one i need).
Cheers, Yetti :cyclops:
Current status.
Flashed the stock T-Mobile firmware to the phone. No success.
Flashed new modem to the phone. No success.
Will go to the T-Mobile store tomorrow to see if they can help (I doubt it but i have to exhaust all the options).
Any more help would be appreciated...
cheers, yetti:cyclops:
By under the battery I mean like to take off the battery cover of the phone and pull the battery out and look at the sticker found there.
G900t.

Yep it says g900t (see above)
As per flashing a modem. I have heard that it is possible to flash any modem for any version of the s5 to the phone. Some work well and others not so much. I have tried 2 T-Mobile modems (baseband) the G900TU1ANCH and the G900TUVU1BNG3 with no success. Do you have any recommendations for a modem to try (or even a custom ROM that might help?)
Cheers,
Yetti :cyclops:
I know that you mentioned they refreshed the service for your number, but do they have the correct IMEI in the system for your account? Metro makes a big deal about that now and you can't just take your SIM from another phone and pop it in a new one and go like you can with pretty much every other service (Cricket is like this too now).
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

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.

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.
