i recently got a Galaxy s2
but i am having some problems with the network (have read many threads, but no fix so far)
so, the phone was 2.3.3 version
i flashed via odin stock roms to 2.3.5/6 version
but - no mobile network, changed different roms and on the KI3 i get 2-3 days using the mobile network, and then it loses the network...
any ideas what i can do?
FIXED
Try flashing different modems until you find one that works well for you. There are a ton of threads on here which have links to modem downloads (and many of them are hosted on sites that still work), search for them.

i tried 4-5 modems...and not working..that's why i said i have read many threads
obviously i have to flash all possible region modems
Return phone to service centre .
jje
Update:
so i flashed few more modems (like 7-8)
and i can see the signal strength is ok -around -60/-70 dBm...so obviously it's ok
and again for a couple of hours network was fine then,,,disappeared
*can't get it back to service center
other ideas?
Has your ime changed?
Does this only happen with your sgs2 or does it happen if your sim is in another phone?
Are your apn settings correct?
Sent from my GT-I9100 using XDA App
IMEI is same, no change
the APN settings are fine
the sim card works perfect with other phones, that's why i think the problem is in the phone
will try with other sim card in same phone and will post result. while waiting suggestions
What model do you have? Check on the sticker under the battery. Checking in settings doesn't show the true model. Eg, I have an I9100T but in settings it shows as the I9100 because I use a I9100 rom. I get crap reception on all roms until I flash an I9100T modem.
Sent from my GT-I9100T
it's a gt i9100
so same as in settings
still no other sim card to check
did you try the kg9? in which modem you were in 2.3.3? did you try to return the same? if it does not work I think it's best to bring your phone in for repair
i think no, so i will give it a try
* i am in france btw - do you use the same modem?
with my andy rom i'm in LPB modem and it work very fine but before, i was in ki4 or kg9 and i don't have problem with it
So FIXED
obviously it wasn't a modem problem, but sim card - wasn't working with no matter what sim card. So i did few times the hard factory reset and used again Helroz application from the market, and on the 3rd time, it worked.
10x for the help and the advices guys
what leaves as a question is : am i going to be able to flash custom roms, and what is changed after the use of Helroz application, so i can do backups?

Hi guys
This is related to my brother's Galaxy S II. He had been using it for a couple of weeks when suddenly (according to him, wouldn't say if he dropped it or anything), he got disconnected from the mobile network.
He rebooted the phone, and got a no service error. When going into Mobile Network settings, it reads 'Insert SIM to access mobile network settings', even with the SIM inserted.
I tried his SIM in his phone - no luck.
I tried my SIM in his phone - no luck.
I tried his SIM in my phone - works.
Tried flashing two new ROMs - no luck.
I suppose this is the phone's SIM reader, then, but have you had any similar problems with it? Do you reckon this will be covered by warranty?
Thanks in advance.
You tried his sim on your phone and no luck? I thought you said his phone is the one wiyh no signal? Anyway, can you still see the imei on his phone?
Sent from my GT-I9100 using xda premium
Yes, I tried his sim on my phone too, just to see if the SIM was broken (which it wasn't). His phone has no signal, that is correct.
IMEI and IMEI SV list 'unknown' in phone info, but on the original boxing it's listed as 358150044627942.
Baseband also Unknown?
Maybe he flashed some custom Roms and lost his imei.
Sent from my GT-I9100 using XDA App
Yes sir, Baseband is also unknown. He wouldn't know how to flash custom ROMs, so I doubt that's the case.
Is this something we can fix ourselves, or would it need shipping off to service?
Thanks.
If you are sure that he doesnt flash any custom rom and only update with KIES you should bring the phone to Sammy support.
You can search the forum and find some threads were people lost their IMEI 'cause they flash custom roms. Then you can recover it when you backuped your EFS.
http://forum.xda-developers.com/showthread.php?t=1261948
But in this case you i think you havent any EFS backup.
My mistake: I had flashed LightningMod to his phone, but he had no problems using it after I flashed it -- the error only appeared after a couple of weeks.
OK, so seems like we're just gonna send it to Samsung, as I'm leaving the country on Tuesday anyway. Have reverted to stock rom and kernel, and I guess we'll blame it on KIES or something. Judging on our past experiences with Samsung it shouldn't be a problem anyway.
Please use the Q&A Forum for questions Thanks

Hi,
I´ve been having a serious issue with my phone.
- I´m not using the phone, people call me and get a busy signal.
- I´ve tried calling my self from a landline and realized this is true.
- I´ve tested calling my home´s landline and got a weird beeping sound and then the call was not completed.
- I´ve rebooted the phone and the issue was fixed, but after a while it reocured.
Any thoughts on how to fix this?
I was just wondering if its a SIM issue (rather than phone). Maybe try a different SIM and see if there's a different result?
Sent from my GT-I9100 using xda premium
- I´ve cleaned the SIM card and the SIM card slot, put it back in and made a couple of teste. I keep getting the busy signal even when the phone is not being used. Now even after I reboot the issue sometimes happens....or if it doesn´t happen it starts happening after the phone goes to sleep.
Could this be the phone´s modem? This is a serious issue.
You can flash a new modem from the modem thread .Or ask for a new sim card .

I got the lastest "Test Mode" firmware from the program "Check Fus Downloader" for you.
Product Code: GT-I9100LKAEPL
Latest firmware: I9100XWKF3/I9100EPLKE4/I9100XXKE7/I9100XWKF3
Is this the correct one??? If so you could try the following if you already have root and CWM Recovery installed;
Type into your phone dialer *#1234# and write download your existing 'Phone' (Modem) version, just incase you wish to reflash that.
[MODEM] Main modem XX versions flashable through CWM
Immediately before flashing, I suggest you take nnote of signal strength; Phone Menu / Settings / About Phone / Status, you can then compare.
Download the closest matching modem and flash through CWM Recovery. The closest I can see is XXKF2.
If you still have no luck, could also try the latest one as well. Be aware for any change in signal strength, quality, not obtaining 3G, H, H= etc.
Hope this helps
Hey guys,
I have a problem. My phone and wifi work but as soon as I switch off wifi I cannot get data connectivity.
1. I haven't changed my provider (Blau.de (Germany)). Used the phone before and it worked.
2. I use Siyah-Kernel 4.1.2
3. I use Dual-Boot (Primary is CM9 (stable)/Secondary is MIUI)
3a. When I installed Roms I made a factory reset/format data plus usual wipes
4. Modem installed is LPS (plus I used GetRIL to install right RIL)
5. I checked the APN and everything is as it should be
Any idea why I have this problem? And how do I fix it?
Best,
Medienkind

Yepp, I have.
And I want to add that I use ExTweaks with the Siyah-Kernel and I put the profile on "battery".
I tried flashing all kinds of ROMs and nothing worked. Went back to cm9rc, tried resurrectionmix etc.. Feeling kinda helpless. Using LQ6 modem atm but no reception. I have installed the right RIL as well.
There are quite some people with this problem but no solution yet.

Does your SIM show 3G in another phone?
I think I'm interested in your case now
Swyped from my Samsung Galaxy SII
Sometime it's just the sim card btw changing to a new one can improve your data speed by a lot I was getting 2-3mbps with old one and new 5-8mbps
I will try a new Sim card. But I cannot do that right now because people need to phone me.
Anyway, I tried my Sim in a friends phone today and I could not get any reception either. I talked to my provider who just told me to use a different password for the APN settings which did not work.
Looks like I have to try the "new sim card" method.
Blau losing signal
Hi! I have the problem as you with blau.de? Did you manage to solve it? I also lose signal a lot and I have to put the phone in airplane mode and then disable it to get signal. (Or reboot the phone). Does this happen also to you? Which modem are you using?

I am still waiting for my new sim.

This is funny.
Today I have received my second new sim after the first one I ordered wouldnt work.
I just put it in, restarted my phone and: IT IS STILL NOT WORKING!
Now, I kinda dunno what to do anymore.
And while I was waiting for my new sim I sent my phone to Samsung because of some warranty issues. They repaired it, sent it back and confirmed that all connections are working.

Well I haven't done this with my brand new sim but I did it with the one I had before and I had no reception.
I believe my APN settings are correct because they were set up through the sim.
But I will try the new card in a different phone and then get back to you.
Btw: I was trying USSD-Codes today and the *111# does not work. I get an error saying: Connection problem or invalid MMI-code.
News: I tried my new card in a HTC Sensation and it didn't work.
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?

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?

Suggest you start by reading the stickied faqs and guides .
Or take the phone to a service centre .
I have just rang tesco and my imei is not black listed. relief
I have not done any thing it was working perfect couple of weeks. i thought it might be tesco as they are upgrading networks now and then but no.
I have not put anything stupid in the phone or installed a custom rom.
I have just reinstalled the firmware via kies and still no luck it just says emergency calls only when i drag the top bar and not registered on network when i try make a phone call

This suggests you need to start at the beginning wipe phone and flash the correct stock rom for your network via Odin .
Its all in the faqs and guides alternative to reading is a service centre .
what modem do i install how do i know and how do i do that.
I have been reading around the forum and people are having same problem.
I was reading this thread is this anything to do with mine (http://forum.xda-developers.com/showthread.php?t=2529127)
is the same problem happening with s4s and notes
Dont know what country you are from...depends on where you live in the general tread there is a modem rill tread.
You can flash these through odin.
Or through custom recovery.
If you dont know/understand these terms you need to read up first
Read well!!!....if you dont know what you are doing you gonna mess it up more than it is now!
