HI,
i have a SGS 3 i9300 that had a bad EFS folder and it wouldn't connect to the network. I was fully aware of of the ramifications and issues of a bad EFS folder so i had it repaired from a service center. The Problem is that even though my IMEI and SN are fully restored( i have flashed multiple roms and they remain intact) I still have no signal and cant connect to the network. Is it possible that the EFS is still a problem or maybe is it a hardware issue? Anyway i can tell?
the phone keeps showing no signal symbol most of the time with or without a SIM card inserted. Also i have tried ariza patch with android 4.1.1
and android 4.0.4 (ariza patch 0.5)
Thank you in advance for all your inputs ,
Erind
No wrong IMEI .Or IMEI blocked by a network
EFS
Wrong modem for network
Wrong CSC for network.
Are the stock answers to network problems .

Well i am going to try i9300XXELLA firmware since a friend of mine has it and its working with the same carrier i have. One question though will this firmware flashing take care of CSC too? or do i have to flash it separately through some other means
Thanks

Depends upon what CSC is in the firmware .

Solved! (kinda)
i installed XXELLA stock rom and than patched with ARIZA V0.5 and there where no apparent changes however this time i had no reception literally no bars just the no coverage sign. Than while i was having a coffee under a cell tower of my operator :cyclops: i had full bars and the phone worked.
Now since it will not work more than 60 feet away from the tower is it safe to say that i have an hardware issue right guys?

Is the fixing of this particular antenna issue expensive? anyone has any experience with this (warranty is loooong gone for me )
when you have warranty you send it to Samsung
i have dropped the phone so there is no warranty on it and that is final.However im really hoping is not a change the whole main-board kinda issue
cause than this phone is to be sold for parts
Checklist .
Is IMEI same as under the battery .
Is your baseband / modem same as for your network .
Have you tried a different Sim
Have you entered the mobile network APN settings .
All yes then possible hardware / antenna loose on connector search for TEARDOWN SGS3 to locate .

everything is ok software wise well nearly everything since im using ariza patch , I made the phone work and all but if im away from the cell tower for more than a few meters the icon changes to no coverage Now i have been looking to teardowns for a while now and the Antenna seems to be part of the main PCB my only chance is that something is loose like you said .
Thanks guys for your inputs hopefully when i get home ill be able to fix it with some handy work and my soldering gun ( or most likely set the thing on fire :silly: )

Hi guys I got a big problem, hope u can help.
I have this phone for a couple month already, when I was still running stock I discovered my cell phone would tell me I got no signal. Turning on air plane mode and then turning it off didn't help to get back signal. So I had to turn off the phone and turn it back on to get back my signal. Problem is I never know when it happens until my wife asks me y my cell phone is switched off. So I went ahead rooting it and I flashed a rom on it. But problem isn't gone. I still lose signal but on this rom it shows me full bars, only cannot make phone calls,SMS,and gprs. Tells me no network or no sim card is inserted. I always have to turn off and turn it back on. Now that it is rooted with whatever firmware I can't bring it to Samsung store to fix
please any suggestions?

Maybe you could try another sim card. Just a thought

Sounds more like a carrier problem. I'd ring them. Check your APN settings too.
Hi,
I have similar issues. Doesn't matter where I am and how good the network coverage is on all other phones around, my SGS2 keeps changing the coverage icon, from 1 to 4 "sticks" of indicator, or to no coverage state (crossed circle icon).
Sometimes the wireless is not working also, or juts gets very weak signal, though the signal is good on other devices near by.
When I try to turn data network (by pressing the power button and selecting data network activated from the pop up) sometimes it's not even showing the data network icon in the system bar (top of the screen), it's like being disabled data network or something.
I can answer a call and stay on conversation for no longer than a minute, then the signal goes dead and the phone just freezes, when I try to tap red button to end the call - no reaction, I have to turn the phone off.
When I try to make a call it just says "dialling" for ages with no result and eventually the phone freezes, so I have to turn it off and back on again.
Sometimes it turns off itself though the battery was showing almost full icon.
I went to O2 store, they gave me new SIM card, but it didn't help, so it's not a SIM issue.
I did a full (hard) reset - no help.
The guy from the O2 store told me, that I can root my phone, and I will not loose the warranty (I purchased the phone only one month ago), only thing I need to do is to revert it back to original state before bringing it (in case of hardware replacement).
But if it is not a software issue at all, so what's the point of rooting and having all the hustle, then reverting, etc... Can there be some hardware issues? I don't know: antenna, RAM, CPU, whatever???
I hope I've explained everything clearly enough. Any ideas would be appreciated. Thanks in advance.
What firmware are you on have you tried to Upgrade via KIES .
Rooting will void warranty and will also increase the custom rom counter from zero . Yes they can be reset in most cases .
Rooting will not fix anything at all .
Network is first check are you getting problems at all locations .
When in the O2 store did they check the signal ???
Choice return to service centre
Flash a stock Samsung firmware via XDA possible to also try a different modem via XDA .
None of these will fix hardware problem .
Personally i would factory reset the phone and check all the network details are correct on the phone then return to service .

when you have this problem check if you have an imei (*#06#) if the response is empty then you have to reflash...
Hi all again,
after posting my previous post I phoned my friend during a lunch break at work. We had a quite long conversation and the quality was perfect. Then on my way home I turned on data network and enabled GPS (LOL), then launched navigation app and it took me home without any bugs (I know my way home though I did it only for phone testing).
Now back home, sitting in my room and my SGS2 starts to fool around again: unable to turn on data network, poor wireless signal (but it's good on my PC), the network coverage icon turns into "no signal" state and comes back to normal again all by itself.
I will definitely test my phone again tomorrow on my way to work and in the office. But it seems like there's something wrong with the place that I live. I've moved in recently and must admit, that all my problems with the phone started only then. And I didn't noticed any bugs while at work or anywhere down town.
Meanwhile is there any way to scan/check the area around my flat? Maybe there's something wrong with the in house router, or maybe to many routers in surrounding flats, or some other equipment/hardware things messing up, or just a mysterious house blocking O2 network and hacking the phone LOL??
The only strange thing is that I'm having not just a network/coverage/wireless issues, but the phone freezes, battery full-empty-full-empty status randomly, etc...
BTW, my details:
Model: GT-I9100 (not a I9100G)
PDA: XWKJ1
PHONE: XXKI4
CSC: O2UKJ1
Android version: 2.3.5
Updated via KIES about a month ago, was working good until now. KIES says that at the moment I have the latest firmware.

Hi guys, I've just got my replacement SIM card today but there is no signal for the SIM on my Galaxy SII Gingerbread 2.3.3. I popped the SIM into my old Nokia phone and it is working fine so I'm pretty sure it's not the SIM. I googled and looked around the forum but found no solution. Already message the carrier and they say the phone is not barred while the SIM is working fine on my old Nokia phone.
In the "About phone/Status" the phone number is unknown, network is O2 UK, signal strength is ok, mobile network type is "HSDPA", service state is out of service. IMEI number is normal. When I dial any number it says "mobile network not available".
If this thread existed before, I really apologize for making a new one. Any help is really appreciated
Have you entered the network details in the phones settings ??

Where'd you get the phone? Sounds like it's a SIM-locked phone...
JJEgan said:

I believe you're referring to the 3g network? If so then my problem lies in calling and texting itself. There is no network signal as there is only a circle with cross. If not, how do you enter the network detail

This phone is an international version I got from my home country Vietnam and it's already unlocked. I was using UK SIM fine until the December holiday. After I returned from Vietnam, the SIM stopped working and I ordered a replacement. Can flashing new kernel affect this cuz I tried some new one during the holiday? The IMEI is still normal though, I checked
i have a problem ...
with miui or wiui , my debit of 3G is bad. I download at 20 ko... with official rom i download a 300 ko ...
why ?

Have you tried the SIM in another phone? Or a different SIM in this phone? Could be either the SIM card is bad (which the replacement SIM will fix), or the SIM card slot on the phone went bad (which the replacement SIM WON'T fix).

Kind of rude to hijack someone else's thread... But I'll answer anyways. My guess is that your official ROM has modems more suited for your country and carrier, and MIUI (or WIUI - never heard of this one) doesn't. You can probably fix with flashing a different modem. But I can't tell you which modem to try.
I have always try e few modem and it's doesn't work .

Try some more. I doubt you've tried them all. Maybe some kind soul who is also on your carrier (which you have displayed on your profile as Orange) in your location (also in your profile as France) can tell you which one.
I popped the SIM into my old Nokia phone and it worked fine so it's not really the SIM. I was thinking maybe there is something wrong with my software but you brought up a good point about the SIM slot I'm gonna try it out and see first
ok . i will try another modem.
thanks
no, it doesn't work ... i have tried a modem who is ok with checkrom or ics or official samsung but don't work with miui . it's strange because it's ok with miui NDT

If you want help you must provide relevant info - and also be able to think a little for yourself!
Have you done anything special to the phone before that? Like programming a ROM in Odin?
Is the IMEI in place?

Hi I think this may be an issue in some parts of the world, but not all. I have regular signal cuts like this in South Africa, but generally only when I'm in an area with weak cell signal. My wife also has a S3 LTE and gets the same signal cuts. When it happens I reboot my phone and it's fine again. I even went back to stock to test and it still happens on stock, just as it did when I first got the phone in November 2012.
I've been on AOSP roms the last few months and then it was fine, no signal cuts. Same with my wife's phone. Now I'm back on stock and the signal cuts are back, albeit not so often anymore, maybe one or two a week. I'm going to run stock for a few weeks and see if the issue persists.
What modem are you using? Have you changed it or is it the same modem that came with your phone?

a MODEM IS A MODULATOR DEMODULATOR . basically the bit that connects to the network .
Modem = Baseband .
\Suggest one factory reset two if that fails service centre and three read the basic faqs and guides .

[Q] People ringing me but the phone doesn't ring while saying "Emergency Calls Only"
Cheers guys! Hopefully i won't be boring you much!
I have this Blue S3 GT-I9300 16GB unlocked. Last week i flashed efeXtreme ROM on it but due to overheating, battery draining and lag, i decided to revert back to a stock ROM. And that's exactly what i did. Can't remember exactly which but it was a 4.3. Anyway, while using the phone with that ROM, i could actually see the phone's signal going down and in a few seconds the phone would say "No Service". At first i thought it was the network / carrier. Tried a Meteor, a Vodafone, an O2 and my 48 SIM card. No difference. So the problem was clearly the phone. And since then the same problem. The funny thing tho, i live 10km outside the closest town, where ironically when i go to, my signal is full, H+ full signal. And when i return, the further i am from town the worst my coverage is, so basically, halfway home and my phone's stuck on No service. With any other phone that i have in my house, S5, Nokia 5230 and an N90, there's no problems.
And here i am now, tried flashing a 4.1.2 stock ROM, nothing but problems. Flashed a few radios, modem_RIL_CWM_I9300XXEMC2, modem_RIL_CWM_I9300XXEMG4, modem_RIL_CWM_I9300XXEMG5, none of them helped. Flashed the Siyah Kernel. No difference. Even lost my IMEI and S/N twice, which weren't a problem for my Z3X. And now, my Mrs. is ringing me telling me the call rings out with no answer while my phone never actually rings and the status bar keeps saying Emergency Calls Only. And BTW, Emergency Calls is permanent now, home, in town, everywhere. Any ideas? Maybe a Custom ROM could help me? Please help me out here lads. Thank you!

Emergency calls is permanent now because constantly flashing from 4.1 to 4.3 as corrupted your imei without a efs backup your only hope is a patched modem and kernel. If that does not work then it is service repair.

Thanks for your quick reply. You see, the EFS is not a problem for me as i can flash, wipe, rewrite it with my Z3X box. With it i can fix Wi-Fi MAC address, Bluetooth MAC address, S/N, IMEI. When my IMEI number first switched to 0049xxx i just changed it back manually with the box and the phone worked fine in town. But i was still hoping i'd make it work at home too!
About the patched modem and kernel. Can you please elaborate on that? I could really use all the help i can get!

When Samsung introduced 4.3 it changed the efs from efsv1 to efsv2 basically to cut along story short this meant in some cases the efs could not read 4.1 modems and in some cases where the efs got corrupt it could not read efs v2 modems as well. So there are some patched modems and kernels in the forum that allow the efs to be able to read the new modems. Look here >> https://drive.google.com/folderview...sharing&tid=0B6MIUd7HJudAbU5YaGkzOUowMG8#list << you need to flash the kernel and modem for it to work (although it doesn't work in all cases)

That's brilliant! Flash a 4.3 stock, and applied the patched radio and kernel. The phone is back to square one now. Which means, i get coverage in town but nothing at home. And 2 weeks ago the coverage at home was decent. Any suggestions for that?

Try a different patched modem from the link I gave you their are a few to try. Obviously the patched modems are working because you can get coverage in town if they had failed you would not get coverage wherever you are. Sounds more like a network problem then the actual phone but like I said there are different modems in the link so one might work better than the others depending on your country etc.
Hi. My Galaxy S3 i9300 drops network connection from time to time for no reason. I have a full coverage in the city, all the signal bars are full, however it drops the signal sometimes and reconnects again. That's very annoying while talking on the phone. What I tried so far:
Clear cache
Hard reset
Changed to another custom stock rom
Installed another kernel and modem driver
All these makes me think that it's a hardware issue. Anyone who knows what it might be and how can I fix it? I have a hot air gun and I am able to replace parts if one knows which part might be faulty on the motherboard. Thanks!
*#*#4636#*#* and change to gsm only (mobile network will not work, changes work untill reboot). Use that if johnny_GSR post dont work for you.
