WiFi not working may be hardware .
Flash stock rom and test fails then you need a service repair .

[Q] No service after installing any new rom?

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 .

[Q] no network after update!!!

So I believe I was on the 4.0.4 when I started. I rooted my phone after only having the phome for a week. I wanted to update my phone so I downloaded an app which would allow me to keep my root and update at the same time (blue android figure as the icon of the app) everything seemed to have worked then I noticed it said emergency calls only and my network was gone. Currently I am on 4.1.2 and my serial number and imei are still the same. I have tried everything, including flashing stock rom on to it ... resetting to factory settings.. EVERYTHING. And it is really bugging me because I only got this phone a week ago
It is a samsung galaxy s3... please can some one help me. I heard people in the other forums talking about modem or efs or something along them lines and I am wondering it might be something to do with that?
Restore your original firmware you saved including original modem and CSC .

Just find your original firmware details or ask a user with the same phone as you or just restore via

Ive tried to flash to a stock firmware from sammobile.. I put it back its orignal firmware but still I was faced with the same problem.
Then I tried upgrading it with a stock firmware off sammobile again and still no service and its prompting me that I have no service.
I dont care about any files on my phone. I just want my signal back and I am willing to do anything to have solved.
Should contact Samsung? As I believe I still am under warranty
Many thanks

[Solved]IMEI has changed, No Network, No Phone Calls (Any Suggestions?)

My IMEI was 353************** and changed to 0499901********. So I am not able to make any phone calls right now.
I have no idea how it happened. I am flashing ROMS for 8 months. I have no EFS backup because i didn't know how much important it was [I AM REALLY STUPID ]
I know 049999**** is a test imei. In every forum there is a solution for SGS / SGSII. There are things for SGS3 but threads are very old like 5-6 months ago and they don't work...
I've tried installing softwares called NsPro or Samsung Tools. But I know they need some special stuffs and they are not free..
I've tried stock roms, modified Roms,kernels,modems after this happened.(Yesterday i was on 4.2.2 now 4.0.4)
So i gave up
Is there any suggestions? Any help way ? Because if I can't find any solution until tomorrow, I'll give the phone to technical service and i don't like it.
Last time I gave my phone to the service it took 25 days and they changed the motherboard with new IMEI (Nokia C7)
And the most important question : Can I update my phone if technical service fixes it? Android 4.2.2 original firmware or 4.3 , 5.0 in the future?
Sorry for bad English.I live in Turkey,Istanbul if there is anyone who can contact me.
Thanks!

If you have no backup there is nothing you can do. Return to stock. If still an issue, needs sending for repair.

Good your issue was resolved. It is always bettwe to keep a back up of efs folder. nv_data_bin would have corrupted which restored on another flash of ROM and you are lucky. Most of the time flashing an unsuitable kernel would lead to this problem.

[Q] I9300 "modified" status WON'T GO AWAY!

Help!
I've been scouring the internet and this site for the past two days to resolve this issue. I am a NOOB and have no clue how to do half of the stuff that's requested to change the device status in order to update my phone.
I am on T-Mobile's network. I broke my US Version of the SG3 and had it replaced by Protect Your Bubble with this International Version. I have tried "Triangle Away" and resetting, rebooting, removing SD Card, "flashing" NOTHING is working.

Factory reset and flash the latest stock rom for your country from sammobile.
For the call issue, check your IMEI number matches the one under the battery and that your sim card is working (try another in your phone)
If still the same then probably hardware fault, visit a service centre.

The other person not hearing you can sometimes be a modem error so root your phone and flash a custom ROM and then flash a different modem.I would say that you will see results doing that.If not then reflash a stock firmware and clear the binary counter and send it away but try a ROM first.
thx
