sim signal problem showing no service - Galaxy S II Q&A, Help & Troubleshooting

My czn galaxy s2 is working perfectly has xwlpd 4.03 except he detects sim but shows no service for sim...

plzzz help me...
i will be very thankful to u.........

Hi!
Since you are new here, it might be the best time for you to read the forum rules just to get you informed.. http://forum.xda-developers.com/announcement.php?a=81 check it out!
1. try inserting your sim in another phone, if you find a signal in the other phone, then there might be something wrong with the s2..
if there is still no signal, then it is a network related problem and call your network operator
2. if you find a signal in the other phone and not in your s2, then you must flash a modem..
DEFINITION:
*Modem/Radio/Baseband is all the same thing and can be seen by going to Settings - About Phone - Baseband. It's basically a driver which receives and sends Mobile Network signals as well as handling switching between GPRS, 3G, HSDPA etc....... (but not WiFi connection, that and switchover between Mobile Network and WiFi is handled by the kernel). Reasoning as to why Modem has no influence on WiFi can be found in this post by Entropy - http://<b>http://forum.xda-developer...count=6556</b>
USAGE:
*There is no one "Best" modem for everybody. Unfortunately you actually have to try to find the modem which works perfectly for you on performance, strength and battery drain levels. The good thing is that from my lengthy 8 month experience with Galaxy S2, I'm happy to report that there are a few modems that seem to perform well geographically for most users. These modems are KE7, KH3, KI3, KI4, KL1, LPS, NEKF2, NELP2 & NELP3.
COMPATIBILITY:
*Modems do not need to be matched up with firmware like it's done with ROMs and Kernels. For example, a KI4 modem can be used with a KL1 ROM and the other way round. The only thing you need to pay attention to is what model your SGS2 is. 9100 and 9100 modems are compatible across both models. However, 9100 model and US variants are not cross compatible since the devices are designed to work on different bands.
INSTALLATION:
*I will add a flashing guide to post number 5 soon, hence why it says "Work in progress.....". For the moment I suggest asking Mr. Google to do a search for you. Bottom line is, for CWM packaged modems you need to be rooted and have a working CWM recovery (flash the CWM modem zip within recovery). For .TAR packages, all you need to do is flash it while your device is in Download Mode and connected to ODIN. The .TAR file should be selected in the PHONE field. Don't touch anything else.
GO HERE TO GET STARTED! http://forum.xda-developers.com/showthread.php?t=1131950
i hope this helps,

[Q] new, just bought samsung Galaxy S2 need help

Hi everyone.
I had just bought the new Samsung galaxy s2,
the attachment got the screenshot of version of my phone.
now I was doing lot of reading on this forum before I do anything.
then I decided to install this http://forum.xda-developers.com/showthread.php?t=1320328 rom to my phone.
now as far as I know that 1st step is to take backup of my contacts and phone data.
then copy the zip file to sd card and try to install this rom as per instruction but then I got confused about " Find the best modem for your network"
can somebody help me with this.
right now I don't know anything about android but I am quick Lerner.
can you explain me what this modem does. If I messed with it, will I be not able to connect wifi.
I had seen http://forum.xda-developers.com/showthread.php?t=1277593 thread. but I dont know what is all about. If I get some idea them might I will understand more quickly..
thanks hoping somebody will help me.
You have an I9100T model phone.
What they are saying is that each user of their clean and simple Rom may have different results with different modems.
The linked modem thread has good info on users experience around the world and what works best in their region for their carrier, mainly for the I9100 model.
Many users in Australia are saying that the I9100T model works best with the modem that comes on the 'T' device.
Read that modem thread for more info and I think there is a link in there for the 'T' model modem thread. Also might help to check out the Australian thread. Heaps of I9100T users comments in there.
Good luck.
Edit: I believe WiFi is handled by the kernel not the modem. The modem is more for connection to your carrier.

Hi, welcome to the wonderful world of the SGS2!
Nice choice on first ROM to try out ;-)
first thing you need to do is root your phone and install clockworkmod and superuser. http://forum.xda-developers.com/showthread.php?t=1075278 is a really great guide and source of the knowledge. That thread is where I started from to learn the ways of android.
regarding the modem: this relates to mobile cell reception rather than wifi. Some different modems work better than others, latest is not always best. The modem can also be network carrier dependant.. Network 3 optimised have always been the best for me. Modems can be flashed and tested fairly easily once your accustomed to your rooted phone and using cwm(clockworkmod).
Hope this helps!
thanks for the reply guys.
now I am going to play with my phone 1st time.
now I want to know if I messed up something. if there are option to restore the phone to its default level or not.
thanks waiting for answer.

1. The yellow triangle is present because you flashed a unofficial kernel. There is a way to remove it in the thread OR you can buy a jig off eBay and just plug it in.
2. Did you set the connection settingin the notification bar/ settings? You can also try to reinstall the drivers for your phone.
Thanks for reply guys. I fixes the usb prob and order the jig form ebay. Thx

Hi Friends,

I think I got my answer here

now I downloaded the old old bootloader...
but I dont know how to use it,
I try to search some tutorials from net but didnt get any. can anybody help me. please...
This is what intratech said about halfway down the 3rd post in his official firmware thread.
***********
If you've already flashed a full package from elsewhere and cannot reset your binary counter using the Jig just flash this package in the PDA or Bootloader (Yes both will work) section of Odin to replace the bootloaders and then you can reset the counter:http://www.multiupload.com/LQQBRQVJUD

[q] sgs2 "not registered on the network"

Hi there.
I'm running into a specific problem with my SGS2.
After successfully upgrading to multiple Stock ICS from this thread : http://forum.xda-developers.com/showthread.php?t=1544487 , I keep receiving the same message when I try to make a phone call : "NOT REGISTERED ON THE NETWORK".
The phone is not picking up my network and it's on Emergency calls only.
At first, 3G/HSPDA connectivity wasn't working. Only WiFi was working.
However after following a procedure on another thread, I entered the code *2767*3855# immediatly after flashing yet another stock ICS rom.
To my surprise the 3G/HSPDA connectivity was working this time. I took as a sign of victory, but that was only short noticed since the phone was still on Emergency calls only and it still gave me that network error message.
Guys PLEASE I implore you to help me find a solution.
I've flashed the above stock rom (using ODIN of course) in the following order :
1.) I9100XWLP4_I9100LUXLP1_LUX
2.) I9100XWLP7_I9100OXELP7_SER
3.) I9100XWLP7_I9100XEULP5_XEU
What could have possibly went wrong ?
I reside in Cape Town, South Africa. I did the flashing for a friend and his network works just fine....
Any help would be greatly appreciated.
Kind Regards,
Steve

Bumping posts in a short time space is not allowed this is not Samsung service fix your phone forum .
First is to check you have the correct IMEI on your phone .
If not then restore your backed up EFS folder .If you have not backed up EFS then you need to start reading the IMEI and EFS posts .

Hi i am having the same error, i have tried two different versions of ICS both are official versions. They both install fine and after the phone reboots it goes straight to the home screen without asking for the code. The data network is not active as well as the phone. When i try to make a call it gives me the
"not registered on network error"
I have even tried updating via kies which produces the same result.
The last two installs i tried was with ODIN.
I have gone back to version 2.3.4 which is working fine
any help will be greatly appreciated thanks you
Rohan
Remove battery then check on the underside of the phone your model no.
What country ?
What carrier are you with?
What ICS are you trying to install?
Which gingerbread are you able to use?
PS you can find out which firmware you are on by dialing *#1234#
Post your information

Definately the firmware for South Africa; "Samfirmware shows both to be either Vodafone or XFM".
While on Gingerbread backup your EFS using HC-Ktool or any other EFS backup tool if thats not available in your country.
You could then if needed restore using the same app.
What sort of code do you normally have to input before you get to your main home screen?
Do you do a complete data/factory reset and full wipe/format system before installing new firmware.
Sent from my GT-I9100 using Tapatalk 2
Hi it's a sim card code i input before i get to the home screen. I did a factory reset and erased the usb storage, and then i used odin to load ICS on the phone.
So you say it must be the firmware since i am on MTN and i am trying to load a vodaphone rom?
Try a firmware from here:-
http://forum.xda-developers.com/showthread.php?t=1075278
instructions of how to flash are also posted there.
Look for your region or a multi CSC region.
(taken from a previous post).
Copy your internal sdcard and external micro sdcard to your PC.
Boot into recovery. Data factory reset. Advanced option, wipe dalvik cache.
Mounts and storage option, format system; data; sdcard.
Also try Ultimate cleaning script
http://forum.xda-developers.com/show....php?t=1166954
Install correct stock firmware using Odin or place a custom rom zip on your sdcard and install from recovery.
Once firmware has booted, from the dial pad, dial *2767*3855#
This will factory data reset.
Wait for firmware to reboot.
Hopefully after that you should be OK.
I got the same probleme some time ago. The only workaround was to switch off the pin-code in settings and then turn it on again...
After flashing a new firmware and do a full wipe, the problem was gone...
Thanks guys i will try both these methods and report back...
First of a big THANK YOU to both of you guys for helping...
-I 1st did a factory reset
-Then Disabled the Sim Card Pin Request
-Downloaded the XFA firmware that you told me to download
-Flashed with ODIN and ICS was working.
Oh before i did all of this i downloaded an official version of Android 2.3.4 and flashed to phone.
I don't know if that had anything to do with it but just thought i would mention it in case it did.
So thanks again guys really awesome...

Flashing back to original firmware , ie gingerbread is always a good idea. On quite a few threads, members have had problems going from one ICS to another.
Pleased it has worked out for you.

you are probably missing the keystr file in efs\imei folder. Just restore back that file and you can use back the sim card pin lock. i had a similar issue previously too.

[Q] Signal Quality on S3

Hi there, im using S3 and ive been curious about the signal quality (network / call) most of the time i see that I'm on "For Emergency Calls Only" on my notification. I didn't have this one when I was using HTC Desire.
I also tried to compare the signal side by side with HTC Desire and S3... It seems that S3 most of the time it shows "For Emergency Calls Only".
Any one here have the same experience?
Additional Note:
- I notice disabling Power Saving Mode makes my cellular/network signal stable at least (good for 2-3 days before going to "Emergency Calls Only"
- There are times that people cannot call/text (or delayed text messages) me. Even in Power Saving Mode Disabled.
- I have a stable Mobile Data/Internet connection, but people says that my cellphone is unreachable, but im connected on Mobile Data./Internet. Text Messages are received after turning off Mobile Data (all of them are delayed)
I hope someone could help me.
Something wrong .
Post has no details so lets guess.
Bad network
Wrong network connection set up by user or wrong CSC .
Modem not suitable for location flash another .

No service/network after Root + Custom Rom Install - PLEASE HELP ME.

I have an S3 i9305 4g lte version, on orange network uk. I rooted the phone using CWM. Then installed the Panorama ROM, using the guide on here. And yes i have used the search function, followed pretty much every guide there is. Still no solution. Im beginning to think my phone will forever be caught up with this problem
on top of there being no service. The phone itself has started to randomly turn off, and also lags!
I regret rooting lol just wasn't meant to be.
Can anyone help me? Literally, I would be so grateful if someone can actually help me fix this problem. I basically just want my network service back, regardless of unrooting or not.
Thanks a million in advance!

Don't let one unsuitable ROM tarnish your experience Try flashing a different modem.http://forum.xda-developers.com/showthread.php?t=1740061
Also, if you're unhappy with the ROM, flash another one. Plenty of good roms out there.

cant find the orange network modem on there? for jb 4.1.2 ?
I'm no modem expert, but search based on your region http://forum.xda-developers.com/showthread.php?t=1356325
Try different ones to see which one works best for you. Also search those threads for your network/region to see what other people are using.
Does your IMEI match the one under the battery?
Do you have an EFS backup?
Also, this is a section for the i9300

i think the problem is with the fact i dont have an efs folder, and that there is no back up either. There is no baseband number on the status, and also no imei is showing.
What do i do?

[Q] S3 "not registered on network"

Hi guys,
i'm an italian boy that has a galaxy s3 with a problem: i can't call or send messages because on the screen there is "not registered on network"
i do nothing, my phone is genuine...i didn't try to change rom or to do something...the problem is appared suddenly.
How can i fix the problem? imei code is intact and my telephone operator didn't block my phone or imei...
i know that in this forum there are some topics about this problem, but it is very difficult for me find them...
help me please...i haven't assistance...
thank you
Look for the serial, if it starts with 00000 or something like that, you nees to use Ariza Patch.

If it helps...
...my wife had this problem last week. Phone was saying that it was not registered on Network. Looked around on the net, checked settings on phone and found that if you turn the phone off for a few minutes and back on, it re-registered to the network. Very basic, don't know why it did it, but it's now OK

This is the problem: imei code is ok but there is "not registered on network"
About the other solution, i'm going to try it but i don't think it will work for me..
Is there a final solution? It is impossible that we can't solve the problem..
Thank you all..

I mistakenly flashed the 4.2.2 leak today and am having the same problem now.
After reading this forum, it looks like the phone has changed its IMEI after using ODIN. I now have an IMEI that starts with 0049. Help anyone please?

Did you back up your EFS folder
otto_di2 said:
This is the name of the ROM I installed: ANDROM3D-VZLA-V3.0 Found it under: Samsung Galaxy S III I9300, I9305 > Galaxy S III Android Development
But now it seems to be gone that post, but it also killed my IMEI.

I did, with team win, I restored but it still doesn't work after restoring. I too have 0049* as IMEI and the serial number is shown. My baseband is XXUFME7. My phone is brand new LOL. Any idea?
Update:
I fixed it applying this.

Hey man I read that it could have sumpin 2 do wit type of modem mg2 or mg4 try searching about which versions of firmware have which on mop
solved it
i got it fixed but i will tell u how it happened to me so u can connect the dots with ur problems ,,
i was on omega rom v49 but i wanted to return to stock and un root (4.1.2) to do some things i had a problem while restoring the cable disconnected but i started the process again and everything worked fine except for the network i couldn't call and when someone calls me it gives him that my phone is ringing and i got nothing (be aware u may have got many calls)
i tried some videos from the youtube and tried ariza patch (i dont no if i did it right or not i choose patch 5 and rebooted but nothing worked ) and flashed some modems but nothing
so i flashed back to omega v47 it is MG2 and every thing worked just fine after that so give it a try i hope it helps
goofy n desperate theory

hey peeps wus happening... i had this goofy theory coz this problem to me is like a villain in a game that needs cheats to beat him ... its the one that bit the dust huh.. it seems that we need to pay cash in this (serious amout too)
anyways here is the theory .. (what if we went way back to the first omega rom n kept upgrading till the latest one ... could it be the solution ... ??? LOOL its goofy but u know when ur desperate u think about some crazy stuff... so thats what i thought about ... coz there r many users who flashed older roms n it worked for them ... im just saying ... lets try to track our histories of our roms n c what happens ... thank u ..
