Slimkat Network Connection problem - Galaxy S III Q&A, Help & Troubleshooting

First, Hi. I have a Galaxy S3 International Model, I live in Central America (Panama to be precise) and I installed the ROM Slimkat. Is very smooth and fast and simple which I like but my network conection comes and go. Is like it comes but immediately it goes. So i don't have Data nor signal to make calls/SMS.
And the most strange thing is that I have the IMEI in the phone, just that my network connection leave and come. But comes for only 5 sec, so it is always with no network status. I made an EFS backup and restore it but no results.
I would be really greatful if someone can give me an answer.
Cheers,

You need to ask the network if they are having problems .
Have you checked /remade your network settings ??
Could be a rom problem a modem problem a sim card problem or even a CSC problem with wrong settings .
Check settings clean sim card that does not help put your phone back to a warranty state flash stock rom and clear rom counter . Test if faulty take to a service centre .

Im on 3 also i have had a few times the same problem mate, lets say maybe 4 or 5 times, it usually happens if i lose my internet connection it still shows me having signal but cant make a call or sms. i got no answer from 3 either
Check the status screen. I get this and when it happens where it should say T-Mobile it says Emergency Calls Only. I figured my SIM card was at fault so wedged some paper behind it to hold it in place and the problem has almost completely stopped.

Are you guys running an I-9100T from 3? All modems from any rom you install won't work with the T. You'll need your stock KF4 modem.

I had a similar problem. Read more about it here:
http://forum.xda-developers.com/showthread.php?t=1225849
tried going back to kf4 still no luck its only in certain places in me house where it does it everywhere else i have 1 or 2 or none at all bars of signal
3 customer service rang me up told them i wanted cancel the contract bcus of it. they knocked the contract price down from £30 to £25.75 for the text 500 plan with them. bit annoyed that i can only get signal in certain places of me house but cant argue on the price as well as gettin the phone for free
because 3 dont have a 2g network in the UK so if you dont have 3g coverage it will show a network signal but you cant make calls or sms
I'm having the same problem but with o2. I lose signal regularly at home as I live on the perimeter, but when I get signal bars back againwhen i go into town, it tells me that the network is unavailable. I have to switch off and on again to re register and then it works fine again until the next time the signal is dropped... It's annoying in the morning because i can wake up and see full signal on the phone all morning, but people are trying to contact me and not getting through because in reality, the network is not connected! I'm sure o2 have a 2g network, so I would presume it's a phone issue...
Hi all,
I live in France using SFR network and I get the same issue here using KI3 but I had the same problem with KH3.
the behavior on the phone is network seems to be good everytime/everywhere but sometimes people who try to reach me go directly to my voicemail and I receive sms with some delays.
When network works again, I mean I don't see it but I know it because I receive a couple of sms at the same time and a call from my voicemail
it means that my phone seems to be connected to the gsm network but is not, It loose the gsm network...
If you can give me your experience.
thx
I've got the same issue. (tacticman), I'm also on SFR network, i had this since KH3, never before. Now i'm on KI3, it's still here.
I always use CF-Root kernel, i tried to wipe, restore old backups, it does not change anything. I also tried GS II repair tools, nothing too...
The only thing I found to solve (temporarly) the problem, switch to offline mode (mode Hors ligne in FR) and then disable it.
But the problem occurs very often, it's very disturbing.
My IMEI number is still here.

[Q] SGS2 no signal 3 network

Hi all.
ive been floating around the forums for some time as an unregistered user but i now have to resort to posting for help.
fist of all heres my details
Android version 4.0.3
Baseband 19100XXLPQ
Kernel 19100XXLPQ
Build IML74k.XXLPQ
ok so first of all id like to know if it matters that the serial on the phone does not match that on the sticker behind the battery although the IMEI number does,from what ive read on the forums this may be because i flashed a non official ROM?
when i originally flashed to ICS the signal was poor but i still used the phone and now i have no signal at all at home,
if i try and dial a number i either get `mobile network not available or not registered with network.
ive flashed the phone with so many roms,kernels and modems now that im in a complete mess with what ive actually done.
i checked with my provider `3 UK` if the phone was/is blacklisted but its not,ive had the sim replaced with a new one and also tried another 3 payg sim.
im not normally one to give up but i admit im getting close to it.
in hind sight i wish id taken a full back up whilst on gingerbread or even never upgraded to ICS in the first place ..ah well
so my thanks in advance if someone can help me and apologies in advance also if ive missed any information out.
cheers
theredi
just to add to this,
i just stood outside and scanned for networks,the 3 network appeared but when i select it it says:
your sim card does not allow a connection to this network
i spoke to 3 just incase its their end but they insist its nothing to do with their sim and is my phone thats the problem.
this is a sim only contract by the way the phone did not come from 3.
so u hav no signal??
imei may got reseted..
flash stock rom an c....
jus my sugettion wen in xda don float get registered
i have no signal or at best its extremely poor,just enough to scan for a network.
what do you mean imei may have been reset? the imei is the same as it was originally.
and ive flashed lots of stock roms and had no luck as of yet.
just tried android 2.3.5
Baseband 19100XXKI4
Kernel 19100XXKI4
Build gingernuts XXKI$
and its exactly the same :S

I meant have you entered the networks settings as supplied by 3 or are you hoping its auto set up after multiple flashing you may have wrong CSC .

so is ur prblm solved did u enter settings as jje said,,,,if ur phone is working fine now,then post
no my problem is not solved however i have some updates after driving around the area (going to the pub)
ive not changed any network setting as i see nothing there to change.
i managed to get a few signal bars and searched for available networks,3 was ther,when i selected it i got this message:
unable to change networks while data service is in use.stop using current data service and select another available network?
i said ` ok`
...registering on 3...
...registered on 3 network.
after this i was able to make a call.
i noted some info at this point incase it has any relevance :
Signal bars: 2
signal strength -109 dbm 2 asu
Mobile network type:9
service state: in service
network:3
phone number : unknown
this happened in one spot on a 1 mile journey.
and now im back at home the signal is back to nothing.
the 3 signal in this area is normally pretty good so something isnt right
the info now is:
Signal bars 0 - 1
signal strength -111 1 asu
Mobile network type: unknown:0
network: unknown
service state: out of service
mobile number:unknown
ive always had a good signal at home and for all of the journey i just made but now it seems to only pick up in a very limited spot.
ive not entered any network settings at all,like i said theres not much i can see that needs changing?
thanks for your input guys its really appreciated.
I don't know if its your issue,but I had several phones on 3 which all had awful signal strength- I just changed to a different network.
Sent from my GT-I9100 using XDA
3 isnt the problem here,everything was fine until i started fixing things that arent broke, and im old enough to know better :S
ive been with 3 for as long as i can remember with lots of different phones and never had any signal problems where i live up until now.
still unsolved
Weird. I have exactly the same problem. except Im on irish network meteor. same symptoms. ben on ics for ages, flashed a cm9 rom. nothing unusual,bam. no signal or very little.
try flashing NEKF2 or NELP3 modem
I have issues with 3 UK too, mainly because I like having the option to switch back to 2G to 3G to H, but 3 doesn't like the idea of GPRS so that's out the equation Plus, the network is pretty piss poor. I'm looking for a better modem, in all hope.

SGH-i717D Fido Netowork/Modem issues - How to dump NVRAM/force Qualcomm USB Settings?

Hey guys... I just picked up a
SGH-i717
v 4.0.4
Black Star V LF6
LTE Sim, LTE phone, downtown Toronto
I just picked the phone up on the weekend.... It's my first unlocked phone and my first rooted phone. I can't seem to get a network connection (I'm with Fido).... initially I tried a number of APN settings as I browsed through various threads on APN settings for Fido, Android and Galaxy Notes. Over the weekend I had connection of approx 1 to 2 bars, and was at least pulling light bandwidth off the edge network. I called Fido last night to have my network settings reset, and since them I haven't been able to get on my network. It seems to jog between no connection, 1 bar and 2 bar signal strength. Where before it said it was on the edge network it now does not connect to a network.
Calls to Fido show that everything is set up ok from their end; they can't support a non-Fido phone, and they say that they can't guarantee I'll get more than 2 bars connection on any non-fido phone. I was making calls & texts from the phone on the weekend whereas now, following the network reset from Fido, I have no connection. Yet when I Reset to Default the APN settings it populates the fido LTE apn without issue.
I'm lost... could someone please help me out here? I have no experience with either rooted phones or unlocked ones... and my furious googling and thread browsing just seems to be hitting the same recycled threads.
'
Where I'm left is now it's saying 'Not Registered On Network' regardless of the APN setting I use.
You need to check your baseband, or modem. And verify you have the correct one for the fido network.
I Dont know which radio image is going to work for you, but it sounds like the rest of the device is fine.
Check in the general section, and open the "super everything" thread.. There you will find many solution threads, and possibly the correct radio image to get your device running properly.
Radio images are almost always a .zip file that is flashed in recovery. and they are very easy to use. You simply download the image you want to try, and place it on your SD card. then boot into recovery and flash the file....reboot, and test.
You should read up on the flashing method too, and ensure that you understand exactly what you are doing "before" making internal changes to your device.
Additionally, you should make a nandroid backup of your current rom, just in case something goes wrong. then you have the ability to restore the old build and get the phone running again.
read, read, read....it's the only way to grasp this information...
good luck.....g
Thanks gregsarg, that's a great start for me. I will throw myself into that direction. Thanks again for your help.

Well, a slow evening with little progress. After reading much, I ran a backup and tried installing a radio...no error message, just says installation aborted... not sure what tdsp is but I tried downloading and installing goo manager as I read where CWM (which is what I.assume I have now) doesn't work that might, but the installer which was supposed to have rebooted my phone and installed, it did not. This was a good 3 hrs and I was spent for the night. Guess I'll keep plowing away tomorrow.
I created a TWRP backup and have begun flashing different radios/modems... When I try to access mobile networks with the different radios installed none seem to work... .... so far I've tried:
Blaze_4g_LB7_radio_ATTNOTE
icsblaze
ROGERS_MODEM-CWMXLA2
UVLG3modemfori717
VK1_Test
KID_TEST
I've always wiped the dalvik/cache before flashing a new radio. My baseband was i717UCLF6, but after I restored it's now T879UVLG3, which is wierd because UVLG3 was the last radio I installed before I restored. I assume the radio didn't restore and I'm now using a T879 radio as opposed to an i717 radio, but it does not prompt me for a sim card after the restore. I can select a preferred band using the *#2263# command, but none seem to drive a better signal - I'm still idling somewhere between a no-signal and unknown network (most of the time) and 1 to 2 bars. Some of the above recognized my sim and suggested either HSPA, GSM, etc on the *#2263# command, others showed nothing when I did that.
Am I correct in assuming I just need to keep doing this until I find a compatible radio and upon flashing and rebooting it will simply connect with a solid signal? Is there any more specific versions of radios I should be targeting?
Re: SGH-i717 No network connectivity
The modem isn't changed or restored when you restore a nandroid or flash a rom.
If your goal is t-mobile or wind or simplemobile. You have the correct modem installed.
Just go to settings and input your APN and save it. Not every rom has the apn's , and not every carrier automatically sends the apn settings.
Thanks Ranger... my goal is to get it working with Fido... but I'm not sure if that's synonymous with T-mobile or Wind yet
and ngretud
Anyone else have any input on Fido radios? I can seem to find one that works for Ontario....
consistent tomsisu
I've now tried the following radios:
ICS Kid
ICS Telus
ICS.zip
ICSblaze
Kid_Test
UVLG3modem
VK1_Test
Every single one upon reboot leaves me with no connection.,, I don't get what I'm doing wrong here... frustrating. Only way I can get any kind of connection after flashing radios for hours is to flash my restore, which brings me back to the edge2 network. I've tried the Good Blaze ICS newamss and the UVLG3modelfori717...n7005amss too, and while I do get a connection it's virtually the same as the existing crappy 0 to 1 bar, or none with a no-connection symbol.
Any help guys?
Anyone at all? I get weak to no.reception in most places and when I leave the city I have no.connection at all. If it was the radios then why wouldn't trying all those radios show improvement? At this rate I am considering just scrapping the whole thing and getting a phone tats locked to Fido if this is the best there is.
Is this the right forum for this?
Re: SGH-i717D Radio/Modem for Fido - help!
There is no such thing as a Fido radio. You flash a T-Mobile compatible radio (recognizes and uses the two bands/frequencies AWS), verify the baseband in phone settings is the radio you flashed, input the correct APN settings for Fido.
Things to check: your sim works with data in another phone, data is enabled in phone settings.

Thx... SIM works fine, data is enabled. Phone always says unknown under the baseband on phone settings. Pretty confident APN settings are fine, I had them confirmed with Fido. Is it just I haven't found the right modem/radio?
I tried the ones I've found most common in threads: iceblaze, KID, VK1 and even an UVDLE from an S2 thread.... still getting the same low, low signal, 0 to 2 bars with intermittent EDGE:2 signal.
Re: SGH-i717D Radio/Modem for Fido - help!
Ok, so you are sending/receiving data. But is that only using EDGE network or have you connected to 3G data network?
And if you don't have a baseband, the usual remedy is to return to stock at&t ICS rom and reflash your preferred modem.
Have you had better data strength with another device? Maybe two bars is all your location gets.

I know we are conversing privately but I'll continue the responses here in case it benefits someone else. I haven't been able to connect to a 3g data network yet.... Because my unit is an i717D (Telus), do I need to flash to the stock Telus ICS rom or do I need to use the AT&T rom?
I was using an HTC One S, same network but locked to Fido, default OS, same SIM card, and was getting perfect signal and data speeds. I can't see how a place like downtown Toronto would yield any signal issues... like you said it seems like it's a radio/modem issue.
Re: SGH-i717D Radio/Modem for Fido - help!
I hate to suggest it, but one old dependable T-Mobile compatible modem:
http://bayfiles.com/file/6FwV/WrxD5a/Blaze_4G_LB7_radio_ATTNOTE.zip
Its been modified and many have had success with it.
So I have flashed a stock Telus ICS ROM, and along with a stock Rogers radio am getting a baseband I717RUXLF4, Edge:2 signal, and even Fido under network. Getting 1-3 bars signal strength, but still no data.
I tried flashing like 5-7 ICS radios and all of them produced a 'no sim' on reboot. I had to re-flash the stock Telus ICS rom and the rogers radio to get it to read a SIM again...
Super frustrating as I feel like I'm going around in circles never solving the issue here...
Does anyone have experience with Fido modems in Toronto or Ontario? Everything I seen to find.is either for.Telus, Rogers, Wind or Bell...
Sent from my SGH-I717D using xda app-developers app
Another update for no one to read....
Tried flashing the Perfection ICS ROM... got same signal issues, installed the Rogers radio that seemed to work incrementally better with the stock Telus Rom... still floating around the issue of low signal...
There is a shockingly little amount of documentation on Fido setups here... most everything is either Bell, Rogers or Telus, with some Wind and Mobilicity.
Can ANYONE please provide me with some direction here? I think I've done my due diligence and respected the process for new people that these forums demand in terms of reading, research and such... I haven't spammed my issues anywhere else, and clearly seem to be stuck on this issue....
Ok, you need a modem that is 850/1900. at&t is 900/1900. So thats why you get 2G because in some areas you connect with a weak signal.
The Canadian stock rom and the Canadian stock modem for Rogers should work.
In network settings you may be able to select network frequencies. If so, select WCDMA only so your phone stays on 1900.
If that doesn't work, dial *#2263# and find the band selector, and select 850.

[Q] network issue

First, Hi. I have a Galaxy S3 International Model, I live in Turkey and I installed the ROM Cyanogenmod 11. Is very smooth and fast and simple which I like but my network conection comes and go. Is like it comes but immediately it goes. So i don't have Data nor signal to make calls/SMS.
And the most strange thing is that I have the IMEI in the phone, just that my network connection leave and come. But comes for only 5 sec, so it is always with no network status. I made an EFS backup and restore it but no results.
I would be really greatful if someone can give me an answer.
Cheers,
Flash another modem

Check your apn settings match the ones for your carrier, sometimes these get deleted or not carried over when you first flash the rom.
I would hold off flashing another modem especially since cm doesn't touch the modem and it will still be the same one from your stock rom, assuming you came from stock of course.

No network signal

Hi to all.
I put Cofface's cyano into my Redmi 3 a week ago and it worked fine except for the network signal that seemed to me to be weaker than on stable or dev miui rom. Yesterday I don't know what i did, i just switched the network type from the services menu (*#*#4636#*#*) to see the signal strenght of 2g/3g/4g and after doing that, the phone stopped to take signal with my SIM in any network type. So i switched back through MiFlash (and selected flash all option), to the Dev and also to the stable rom, but now I just have 4G working.
I tried to put again CM and i get no signal in every network type, even trying to restore a nandroid backup that i made when the phone worked. I also tried to flash through fastboot the NON-HSLO.bin took from developer rom, but nothing changed. What could it be? Where I live the 4G is not everywhere so most of the time I'll be without signal and it would be really frustrating.
I tried my sim in a Samsung phone and it takes both 2g/3g (the phone doesn't have 4g) , but trying another sim in my phone (of the same carrier) gives me the same result of above : only 4g . While on CM that sim could connect (only 4g) but mine not.
Please help me! :crying:
sorry if i didn't explain myself well, but I'm not english
EDIT: with the 4G i can only surf on the net but i can't make or receive phone calls. I'm giving up on this phone
EDIT2: following some guides I erased modemst1 and modemst2 but now I'm unable to get IMEI and I have unknown baseband
I have the same problem as you (almost)
http://forum.xda-developers.com/redmi-3/help/cellular-network-redmi-3-t3370459
I also have poor reception and can't make any call or receive them on any band 2g/3g/4g and i have this problem since I received the phone.
Did you fix your problem??
I have the same problem of very bad cellular signals.
with the same carrier, when other phones 2 samsung, 1 chinese (cheap unbranded), one very old nokia all have good reception, xiaomi redmi 3 pro is inaccessible from other phones.
today I'll try to install some signal booster apps from thestreet.com/story/11733410/1/7-apps-that-improve-smartphone-reception.html hopping for the best.
if anyone find any solution please update
