[Q] Galaxy s3: No WLAN and no Mobile Network - Galaxy S III Q&A, Help & Troubleshooting

Hi,
I bought a used S3, with a small crack in the screen. Otherwise the phone should work.
When I got it, i reset it to factory settings, because it wasn't.
After reboot, the phone worked, but I can't go online with WIFI or Mobile Network. I also can't phone with it, it found no Carrier!
I flashed some other original Samsung ROMS with odin, but it doesn't help.
If I activate Wifi Tethering, I can see the S3 in my WIFI Network.
I can see the IMEI in the settings. It is the correct IMEI, I compared it with the IMEI on the cover and on the bill.
Can anybody help me?
thanks in advance

Hi,
I suggest the same, but I thought, that I put the convenient firmwares on the phone with the official Image.
In every Image I tried, there was a modem.bin The IMEI is ok, so I hope the /efs is not corrupt.
I never rooted the phone,....
Maybe a custom ROM can help?
thanks in advance

Hi,
I recognized the the wifi is ok if I am close enough
to the wifi router (10cm), maybe the mobile network is also ok if I
close enough to the sender.
Do I have problemls with the antenna?
Thanks in advance

network not work

greeting
I Downloaded a stock rom from SamMobile (I installed with odin) and no longer connect to the mobile network
(January 2013 4.1.2 I9300XXELLA I9300OXFELL1)
I reinstalled the original ROM (all of SamMobile) and now can not connect at all to the mobile network
(January 2013 4.1.2 I9300XXELLA I9300VFGELL3)
I tried with (pacman rom) and still do not want to find the mobile network (everything else works)
in the SamMobile download is a dll should be placed somewhere? where?
what I did wrong and how to fix?
check your imei

ok, what should see or know?
I can not figure out what to check?
please can you be more specific?
thanks
R: network not work
To check imei go to settings>about>phone state (raw translation from italian but it cant be too different). I believe glebun is suggesting u seriously f***ked up ure phone, so u should check what imei u got and post it here.
In this phone (gs3) some things about the network are closely connected to the kernel...such as mac address...
have u tried chamging it before? Or changing phone's network name or ip?
try flashing a different kernel...also you've never touched the phone's modem before right?

Google "how to check imei". how hard is that?
Check also the modem version, if the one provided with the new Rom is not compatible with your phone networks it can explain it. Even if afaik jb modems are less sources of issues than ics ones. Most of the time custom roms come without modem.
There is a modem correction thread in general section.
But first check that your imei was not wiped.
Type *#06# on the stock dialer.
If the IMEI has been wiped, it's the EFS problem then. Only service centre. Don't think you could solve it youself

Hello,
I don't know the original csc number and region.
Is it possible to decode from the imei and serial number? Or it doesn't care which CSC/baseband/Firmware flashed to the phone?

Where do you live? Google your country CSC code, use link from earlier post and flash it. Get matching modem from here http://forum.xda-developers.com/showthread.php?p=28033515 and install it.
I have succesfully downgraded to 4.0.4, IMEI, baseband, csc is ok. But the phone is rejected from the network after a few seconds. What is the problem?
Thank You,

Ask your network a guess is that the phone has been blocked by the network .

Hello,
I think the APN isn't tuched yet. The correct APN settign is needed for the correct working? Is the phone registered through data channel EDGE/HSDPA? Should i config the APN settigs related to the actual network provider?

[Q] i9300XXUFME7 leaked

Is it possible to update with “kies” after flashing this leaked rom (I9300XXUFME7)?
yeah no root no custom firmware
thanks.
This rom is "open europe" wich means this rom has different csc-codes. Do you know which csc-codes this rom has?
not yet didn't try flashing it though ask in the general thread of the leaked rom there are a lot of people there who can answer you
You wont be able to update with kies if you're on FME7

As ME7 is not a Samsung release the probably not by Kies or OTA .

no you can't do that as it is a test firmware and not yet fully released.

Firmware S3

Hello, i have recently remove a custom ROM and i replaced with an original firmware. Problem is that i don't have backed up EFS folder, and my phone is not connecting to mobile network. I have check the IMEI and is an generic IMEI not original.
How can i find which baseband is good for him?
Flash 4.3 stock firmware, if efs still corrupt then pay for a repair.
I have do that, but is not working .. network mobile can't connect..
Anyone has a solution for this problem?

Try to flash a firmware older than MG4 and start OTA-update. Perhaps this will repair your efs-data.

Not Registered On Network S9+ DUOS

Hello everyone! I have a problem with my s9+ DUOS SM-G965F. I cannot make any call. The carrier is showing, but the signal is dropping.. and then I get not registered on network. I tried:
1. Reset network settings
2. Factory data Reset
3. 2 SIMs different carriers(is not locked), both sims works on another phone.
What can I do? Maybe hardware problem? If hardware, what can be? What piece of hardware? Thank you!
On dialer put: *#06#
If IMEI = 0000000000000 then you can't get a working line because you don't have IMEI.
Cheers.

Did you purchase your mob new or 2nd hand?
I wonder if the hone is blocked / reported lost or stolen in Your country?
Type *#06# and make a note of the IMEI then paste it into https://imei24.com/blacklist_check/
You can also consider flashing the stock firmware via odin. You can download it for free from sammobile
I bought it 2nd hand, I have 2 IMEI s and none of those IMEI are blacklisted. I got the phone to a service and told me it wasn't unlocked properly.

No, it was a hardware problem. A common thing on the s9. I sold the phone.
@cpanait69 I have the exact same problem but it happens like 70% of the time. Started happening since 7 months. Not really sure what to do with this phone now.
