help me please - Galaxy S II Q&A, Help & Troubleshooting

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).

[Q] Need help. GT-i9300 network problems + sn = 00000000000

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.

[Q] Is my phone software unlocked(versus factory) Please helpp?

Hello,
I will have to give background info on this before anyone can help so bear with me please :.
I live in Pakistan and I bought a i9300 directly from samsung. In the beginning of the six months i owned the phone, I never rooted or put custom ROMs on it. Then unfortunately I got SDS. I gave my phone to a local repair shop (non samsung, but highly reliable, I bought the phone from there) who switched the motherboard on the phone. After I got it, I rooted it and started installing custom ROMs on it. First it was cyanogenMod, then Paranoid Android and Supernexus +AOKP and others. Everything worked fine. Then I installed Omega ROM (Samsung based ROM which changes the modem). Everything went fine, but I was unable to connect to my network (No texts, calls, data connectivity). It detected my network(Ufone) but was unable to register on it when I manually tried to. I mega-wiped my phone, cleared cache and factory reset and did everything. Alternatively, the following steps I also tried.
1)Checked if my IMEI is intact. It was. (I have EFS backups too)
2)Checked if my serial # is different. It is still the same (No need for Ariza Patch)
3)Checked if my SIM works. It does on different phones.
4)Checked my APN settings. They were fine. I even manually changed them to match the carriers
5)Changed my CSC settings (using the playstore app). Still doesnt work.
6)Checked different modems from the appropiate thread (I have tried Europe Unbranded, Middle East, Egypt and many others)
7)Restored nandroid backup of original stock 4.1.2 Sammy ROM, still not connectivity.
8)Flashed using ODIN, the stock 4.1.2 ROM for my country (Using SAM mobile). Still no connectivity.
9) Matched my RIL with my baseband (using the GetRIL app), still didnt work.
Stock Samsung 4.1.2 ROM details before OMEGA flash in which everything worked:
AP: I9300XXEMA2
CP: I9300XXELLA
CSC: I9300OJVEMA1
This has happened to me the 5th time now (Phone is currently at the repair shop) and I have sequentially tried every one of the steps I have mentioned. I called up the repair shop and they said that I can come tomorrow and pick it up, all they have left to do is "SIM UNLOCK "the phone. That confused me a lot. I will go tomorrow and ask them details as to what they meant by that. So my question is basically this:
1) Is it possible that the motherboard they put into my phone is from a software-unlocked phone not a hardware unlocked? (Is the 'unlock' on the motherboard of the phone)
2) Is there a way to find out if my phone is software or factory unlocked?
P.S. Every single time I hand in my phone, I obviously unroot it and install stock on it (regardless of the fact that it doesnt connect to the network). But every single time I get my phone back, its ALWAYS ROOTED.. I even asked the technical team guy and he had no idea what I was talking about (repairmen here dont have that much of knowledge, they tend to follow guides online, thats it). So could it be that my connectivity issue is just because its software unlocked and not hardware?
Thank you!
Anyone?

Not a genuine service centre then .

all correct for network suggests a hardware fault .

But it's not a hardware fault? I mean whatever they do, they have to root the phone to be able to do it. Any idea what settings or configuration they might have changed using root for it to connect which I haven't already tried?

Possible solution unlocking international I9300 - Missing Samsung Service Mode menus

Hi guys/girls,
Well I had some issues last week with attempting to unlock an I9300T (same as I9300 only it picks up the 2400hz band from the Telstra service provider) anyway,eveyone was mentioning 'Just flash back to ICS to downgrade the bootloader, unlock and flash back again' or something along those lines. Needless to say the first thing I did was root the phone to back up the EFS/IMEI and in the process of rooting via Odin with CF-Root....the task in it's self bungled the EFS anyway. So corrupt EFS, no signal and IMEI displaying as 0049. On a side note I discovered a new and much easier way of recovering your EFS should anyone run into those sorts of issues.
It was told following tutorials from various sources that the Service Mode menu input for simlock works on international SGS3 models???? Well apparently it DOESN'T....so all my effort was wasted I guess? Flashing the phone and bricking it several times. Anyway my point I wanted to make was that there is quite a difference the Service modes available for Australian/International I9300 devices.
I am curious to know (if possible?) transplanting the serviceModeApp.apk from a device where Network unlock can be performed by simply pinning in the service code via the dialer....to un-sim-lock the device??
Would somebody who has successfully unlocked their I9300 via this method be willing to share their serviceModeApp.apk for me to be able to test this theory??
EDIT: Needs to be Android 4.1.1 from what I have just read now?
Oh and just for clarification, I would be needing the serviceModeApp.apk from the version of Android that you were running when you unlocked your device, not the one you are running now if you have updated firmware versions since then? So most likely I would be asking someone to dig through one of their Nandroid backups to extract the serviceModeApp.apk from that particular firmware...EDIT From reading I believe I'll specifically need Android 4.1.1 (Not 4.0.4 or 4.1.2)
The reason I request this is mainly due to the fact that older firmware versions are becoming difficult to come by since the collapse of most of the major online file-storage providers such as Hotfile. Seems like an awful lot of work for me to go through for one apk also ....then to learn that the one I choose for what ever reason was NOT the correct one for unlocking because of the region and/or service provider the firmware was from or any other long list of unknown variables.
So yeah if someone that unlocked during ICS can fish out that APK for me that would be really appreciated, not only that but if it proves to be successful we will have a lot less people bricking their phones
Many many thanks in advance!:good:

[Q] Phone settings say g900f but odin says g900t

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).

[Q] Official network unlock not working i9300

Hi everyone,
I come to you as I am a noob as far as twinkering with my gt i9300 goes and I think I messed it up big time.
Here is what I did :
I had android 4.2.1 on my gt i9300, the stock rom from sfr (french career).
I network unlocked it using my career official unlock code, which worked great. It recognized my japanese career sim very well (i am in japan now).
Then I got greedy and wanted to update my android version so I downloaded a 4.4 android rom from I don't remember well, and a cwm manager.
The network unlock worked fine at first but after a restart it did not work anymore. It asked me for a network unlock pin.
I thought it was asking for a sim pin at first, which my sim did not have as I hadn't set one. I got mad trying sim pin code and gave up. Had I given it the network unlock code instead of possible sim pin code it might have worked but I will never know.
Then I tried to solve the problem installing android 5.1 cyanogen version but I had the same problem except this time I understood it was asking for the network unlock code. The problem is that when I fed it to him, it did not work, the request was unsuccessful.
So I looked for a solution on internet and found all kind of things:
I read about restoring the efs partition, but i do not have any back up.
I read about installing a stock rom version, change the csc and retry the official network unlock code, but it does not work, whether I restore through Kies (which gives me a vodafone version) or manually (with an sfr version, french vodafone it seems).
I read about installing Galaxy simunlock app after rooting the phone and installing userbox, but it tells me that my locking system is not handled as it is too new.
I upgraded, downgraded, rooted in every possible way but nothing works.
I am running out of solution and I therefore turn to you for help, hoping you will be more creative than me.
I have the official network unlock code, the phone, no back up of any kind and really little hope.
Thank you in advance for any help you could give me !
Have a nice day !
Sadly you didn't make a backup of efs. That should be first thing before playing with customs.
Oh well, I suppose your efs may be screwed up due to entering couple times bad network unlock key.
I suggest go to next corner GSM shop and pay 2400JPY for efs fixing and perm sim unlock. But before that, check your IMEI and serial number are correct. Thay can fix all of this in one step.
You need to do this via box, you can't reprogram that or fix yourself because you did everything that may help and you still have a problem. You can't use any software on efs v2. It will not work.

Thank you for your quick answer !
I will follow your advice and go to a "professional".
However I don't understand how they are able to do what I can't, do they have special softwares or anything ?
I would like to know because I do have the official unlock code.
Also, I would still like to upgrade to android 5.1 cyanogen version, do you think it will be possible after such a modification ?
I should not encounter any risk if I backup the efs beforehand right ?
Thank you again
Service will connect your phone to, so called, box, ie Z3X Box. This is some kind of pc-phone bridge hardware which can alow to decrypt and encrypt efs files, fix IMEI, serial number, flash firmware, IMEI certificate, remove network locks, sim locks etc.
Of course you can backup your efs now but it is corrupted and useful. Backup this partition after repair. Than you will be able to flash anything you want. Even CM12.1,no problem.

P3110 / I9300 / I9100 / NEXUS 5 / iPAD2
Ok I understand better now.
Thank you very much for your answers, they have been really helpful !
Do not let them plug your phone to the box if you want to install 4.4 or 5.0 because if you give them they will replace your imei number with a clon imei number and you will stuck with max 4.3 and you need to install a patched modem and kernel every time you format your phone... tell them to try to fix without replacing your imei number first. Replacing the imei number should be the last thing to do...
Why do you think they will clone his phone's IMEI? It's even illegal.
If someone doesn't know how to use box than he should not work in GSM service.
You can rewrite original IMEI and serial number without cloning anything.
An probably IMEI is fine, it's network lock problem.

Most repair shops dont care its legal or not. Also most costumers dont know this kind of things and as long as phone is working its okay for them. Mine is just a warning to make him look like he knows this things so repairman doesnt do something with no going back...
