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.

Hi there,
problem as follows: I got a I9300 (pre-rootet and with some kind of chinese custom rom based on 4.0.4). I did not put in my simcard, but flashed it straight away with a 4.1.1 custom rom, and did the efs backup.
However, once I put in my simcard it shows no service. I have tried several roms and just restored stock recovery and stock firmware 4.1.1 but nothing has changed.
i have checked this threat http://forum.xda-developers.com/showthread.php?t=1080076 and others, but still my phone is not having service.
I don't think that my efs partition is corrupted since when I type in those keycodes it still shows my imei. also I did a restore of my backed up efs.
Does anyone have any ideas?
Thanks!

It looks like what I am looking for. However, I cannot find the files they are using
I'll keep looking... thanks
Update:
I have asked the person who gave the phone to me, and apparently it was a parallel import to china. However, I have no idea where it is from originally.
I have tried flashing a couple of different stock roms, but without success.
I have also tried to flash the chinese rom from the suggested thread, but it keeps failing when it comes to the part where it wants to install the modem.
Does anyone have an idea how to find out the origin of the phone?
I have tried Kies, entering the model number and serial, but kies does not accept the serial.
My last hope would be that I can find out which market it is from, then flash back the original stock firmware?
Any other ideas why it might show no service?
IMEI is shown, so I think efs partiotion should be still ok, right?
I'd really appreciate any help and suggestions. I am out of ideas...
Thanks
There is some issue with your efs or modem.
having imei does not confirm that efs folder is intact.
No service .
Usual is .
Wrong IMEI .
No Modem /wrong modem .
Wrong CSC / network connections no tet up .
Sim faulty .
Phone blocked due to theft .
Wrong firmware on phone .

IMEI is shown as on sticker.
I have no idea where the phone is originally from - I have contacted Samsung but they were not willing to help- they say it has not been bought in NZ so they cannot help me here. Hence I dont know which modem would be the correct one. I have tried a couple of different ones, but none seems to be working.
Sim is ok, also tried like 5 other sim cards.

That's what I read in other forums now as well.
The error seems to be common after unlocking with boxes.
So I suspect that someone unlocked the phone, which messed up the efs folder. The backup I made when I received phone, must already be faulty.
I also noticed that the SN in the phone settings shows up as a different number than the one on the sticker.
I guess I have to find someone with those 'boxes" who knows what he is doing Any suggestions for Auckland, NZ?
I have been to like 5 shops but noone could help so far... THANKS

Thanks, I had tried that. Kies doesn't recognize the SN. Strangely enough SN in settings and SN on sticker are not the same. I really think seller screwed with the efs partition.
Was it working with the original Rom?
From my reading of your posts you have not changed the modem or csc that it came with?
Perhaps if you tried a 4.0.4 Rom again you might have some luck given it was probably working when you received it.
The different serial numbers are suspicious though. Presumably the one on the sticker is the correct one. Would Samsung not be able to identify the phone by the SN and tell you what the original firmware is?

When I received the phone it was not working. Hence I installed stock rom. I also tried flashing different modems, but nothing helped.
I contacted Samsung service and they said they wouldn't be able to help me because I did not purchase the phone in the country where I live in, and also cannot give me any information about where the phone was originally from.
It possible that is an imei block. If the phone is sold with a subscription and the owner sell it to an other prson without paying anymore the taxes for the phone the operator is able to block your phone using the imei.

Some shops won't buy your phone unless you provide them with proof you purchased it or paid your bill off.

As bought origins unknown .
Non working may be faulty and not fixable .
May have been as said blocked as its a stolen phone .
If it is I9300 then i would be flashing stock ICS firmware with modem and CSC for the country/network you are trying to use the phone on .At least then after a successful flash their can only be two reasons for not working phone hardware or IMEI .
IMEI check

IMEI is ok. I also called my network provider to check if IMEI is blacklisted in my country, but say also say it's not blacklisted.
Someone told me (and I also read it on other forums) that this often happens after unlocks, which are actually not successfully finished.
I will meet him tomorrow and will post an update.
Thanks for the suggestions and help so far.
Ok last update:
Indeed the phone is unlocked and something went wrong with it. Apparently, it is a common thing that the IMEI changes during unlock and then has to be restored, which often causes that problem.
The guy who helped me got it fixed. Only problem is now that I cannot flash the modem file. So have to stick with roms which come without modem. Also it seems that some are incompatible with the 'old'modem
Right now I am using AOKP and everything is working.
Thanks again for all the help and suggestions!
Hello guys, I am kinda experienced with flashing roms and stuff since I owned galaxy s2 for over a year. However I bought a second hand galaxy S3 one month ago and it has a turkish firmware however when I tried and installed a new rom everything seems to work find except the network service all i see is a circle and has no service and i tried many roms even jelly bean rom (which worked fine with my friend's S3) even i installed the same exact firmware that i had when i got the phone with the same kernel but got nothing :/ then i took it to where i bought it and he told me i can not install any rom on it and just the one i had on it then he took it for like an hour and it was working again... but its really bothering me! what's wrong? i want to install jelly bean or cyanogenmod but afraid to lose the service again i read its something related to radio or stuff? so any help please?? and here is a screenshot of my kernel and rom..
I think you might want to flash different modems and see what works best for you

One search before posting and read the faqs and guides before not after flashing .
Two it requires you to restore your backed up EFS as per the faqs and guides .
Not read the faqs and guides and no backed up EFS then you require a service centre .
#But you can try a factory reset and flash stock rom first .

Thanks for the advise. But I did one before posting. Nevertheless I will continue reading to find something useful
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.

Does your IMEI match the one under the battery?
Do you have an EFS backup?
Also, this is a section for the i9300

No rom should ever mess with the IMEI. Also with the proper backups you should not have to worry about it.
You can share ways to trouble shoot it happening but no, no tools or how to will be allowed.

Sir, this "should" is a very interesting word. Yes, no ROM should.. but there are ROMS and I am a victim of such a problem. Forget everything else when I myself am victim of XOLO Q800 Stock ROM which fails to recognise my IMEIs every single time as that needs to be pushed by SP Flash Tool.
The more interesting part is - so far as I have tried my luck - Backup in CWM also fails every-single-time whenever I tried to recover. However, this has helped me build a practice of backing up my ROM every Sunday (but for what?).
Now please tell me how can a noob user like me benefit from such a great resource like XDA in a case like this? For everything else, Yes, I do love XDA since 2008 ever since I joined as it is indeed an unparalleled resource.
I wish 'admin' gets my point, if not what I said in words. Please accept my sincere thanks for that in advance.

See here is the issue. Editing the IMEI in any way is illegal in most of the world and in so such, no threads about editing the imei are allowed on xda. My advise would be to search other forums on this. Other then formatting the whole device and flashing a stock ROM. That is the only advise I can give you. After reading this I researched it a bit my self and seems devices with this chipset are known to have this issue.
