No access to mobile network, tried stock rom and CM - Galaxy S III Q&A, Help & Troubleshooting

I previously had issues with my GT-i9300 using a stock rom where it wouldn't boot past the Samsung screen and in recovery mode it was showing an EFS mount error. I managed to fix it with a file I installed through Odin. I then installed CM through the installer and it all worked ok other than my cellular access. I then installed a stock rom I found and I could see the mobile networks but still didn't get a connection. I then installed cm-10.2.0-i9300 but I still have the same problem. Now I can't search for any mobile networks and neither is it connecting to anything. I've tried putting it into Airplane mode and rebooting but that didnt work either.
I installed GetRIL and it shows I have baseband and RIL mismatch, but when I install other RIL's through the software, it still doesnt fix the problem.
Can anyone help!?!?

Hundreds of identical threads, search and read, also 'efs know this stuff' sticky in general forum.

I did have a detailed look but couldnt find any working solutions for my problem. I realised it was linked to my IMEI being corrupt, so I reset my IMEI with Chimera Tool and now it's connecting to the network but is still problematic. It doesn't always connect calls and I have no mobile data at all.
Any ideas on where I can go from here? I don't want to give up having come this close! :crying:

If you already tried all the solutions in sticky thread then take it to a repair centre.

"I had GB and conect the phone to kies and upgrade to 4.0.3 and since then the wifi does not work, I'll change the phone atrebi thought that putting the 4.4 will fix the poblema iva, and putting it on solpresa was that the phone was still like, do not activate the wifi fails, and tried everything to restore the efs folder, file down to 2.3.6 with pit, factory restrabecer the phone, I've gotten 300 roms and mobile sige therein fails to activate the wifi.
dialing * # 526 # does a wifi test and the result gives me the following message "NotSet driver loaded ng "
Your EFS file is corrupted or missing, and the IMEI number is likely gone as well..

The wifi in my note, did not work, pressing on - off, after trying so manufactured, and put several roms, as usual
So someone in the XDA forum, sent me this, and I used the EFS restore / backup pro, and to restore and give me a note left with a generic imei.
As I can regain my IMEI, and the wifi?
Help, please

[Q] Cannot make phone calls/ send text messages / use data.

My friend asked me to look at this phone that was softbricked and kept going to CWM recovery everytime it was booted. I updated the CWM to the latest touch version via ODIN then formatted the phone clean. :good: Then I flashed 4.3.1 stable AOKP ROM and the GApps. It was fine, everything else was working. I connected the wi-fi, used bluetooth, signed into google account everything was normal and stable.:highfive: But then I tried calling and it said "no mobile network". Tried sending a text, could not. I went in and searched for network signals then registered to the correct(I AM SURE!) one.:silly: Still no luck. Then I let it choose automatically. Nothing. Then I thought maybe installing another ROM will somehow fix it and flashed CyanogenMod 10.2 stable. Still no luck. I searched around for a flashable radio but could not decide if that would fix it because as far as I am aware if the radio wasn't working no wireless connectivity should've been either.
The phone is Samsung Galaxy S III GTI9300 white 16GB (unlocked) and has been here in Nepal with Nepal Telecom Sim since it was bought. I have no Idea how the soft brick happened but I think this guy tried to manually update the phone with a stock firmware during which some **** must've happened.
Can you guys please let me know if this could be fixed?
Any help would be highly appreciated.:fingers-crossed::fingers-crossed:

[Q] Please help, Radio modem problem

PLEASE HELP!!!!
Had a sms problem, then modem seemed to go, tried a fix from these forums, wont connect.
Ok tried the download to MB1 modem/radio firmware from my SD card, cause I am having the same issue plus some, http://forum.xda-developers.com/showthread.php?t=2657822&page=22.
I'm running Carbon Rom 4.4 KK, with no problems except the sms issue.
Flashed MB1 and no my phone wont connect at all except to Wifi. Re downloaded VRCUCML1 cause that's what I had before, Same thing no connection!
Down loaded both from SD card
Fyi I'm new but learning. Thanks Hope someone can help me.
Questions go in the q&a forum, not general.
Check your imei and serial numbers still match those under the battery. Chances are you've corrupted the efs folder.

[Q] Galaxy S III i9305 Wifi Problem

Good day,
I have a samsung galaxy s3 i9305 LTE and I have been using this device without problems for around 2 years now. It runs on Jellybean 4.3 baseband version i9305zhucnb1. It has been running on this firmware for a couple months now ever since it has been rolled out. The problem is, the WIFI suddenly stopped working. Never had this problem before and I actually never had any problems with this device ever. Whenever I turn on WIFI, it detects my home networks and other networks wherever I go but whenever I try to connect, it just shows saved secured, and sometimes authentication error after a couple of attempts. I have other WIFI devices at home and all are working perfectly. I tried forgetting the networks and I am positive that the WIFI password is correct. I tried to restore the device to facroty settings hoping that it would work. I tried accessing my router and I'm sure my device isn;t blocked. I even configured my routers to only accept the mac address of my device and block all others but still wouldn't connect. I tried rooting my device via odin but my device blocks root access and shows the error message "an application attempted to access system on your device without authorization. this attempt has been blocked.". I tried rooting it to try flashing custom roms. I also tried dialling *#0011# to configure my wifi but it still does not work. I don't think that the problem is my firmware because I had it for months and it didn't update before the issue occured. I was also about to try downgrading it to an ICS stock rom since I can't root it to try custom ROMs. I've been trying to fix this for days now. Can you guys give me a step by step instruction on how to fix this if it is at all possible? And maybe give me a link where I can download ICS or lower stock ROM's for this device. I think I have to use a TGY firmware, though I don't have an idea what it means. Thanks!
Wifi module
Maybe you've dropped your phone and the WIFI module loosened, and it can't work correctl?

Maybe it's time for factory reset? I know that's the easy solution and most complicated but you should do it from time to time.

Well, i think this may be the time to perform a complete factory reset ! try backing up your data and perform a complete factory reset.

i decided to have it checked by a local technician and according to them, this was still a software issue. i dont know what to do anymore. they insisted that i should just keep flashing stock roms to fix these. already tried flashing the 4.3 tgy jellybean stock rom so i was thinking of flashing other version stocks. can anyone give e a good link where i can download tgy stock roms 4.1.2 or even ICS stock roms. I also am having problems with rooting the device. it gives me error message "an application attempted to access system on your device without authorization. this attempt has been blocked." after flashing autoroot in odin. my knox is not installed. thanks.

If they think it's a software problem,why didn't they fix it?

dont know
the first time i brought this to them is when i attempted to flash an incompatible firmware. they also did not fix it. they said they dont have any available stock rom for i9305 and told me to download and flash one. mayba im just gonna have to look for a different technician when i have free time. so for the mean time, im trying to look for other fixes. btw, i tried downloading a tgy 4.1.2 stock rom and it does not flash successfully. for now i'm thinking of rooting and flashing custom roms. but whenever i flash auto root. it gives me the error message "an application attempted to access system on your device without authorization. this attempt has been blocked.". i tried updating supersu still the same thing. i manually installed root checker and says it does not have root access and it shows the said error message again. what should i do with that? Thanks

It all goes great and finally I have cwm recovery phone, i want to install custom ROM in it because its GPS was not working and when I connect to WiFi it start downloading unwanted app oror adult apps(kind off virus).. So I add a custom rom Aosap 4.4.4 from needrom.com by Naveed, but there was no network signal, but when I go back to my backup my sim start working with no problem but I can't stay on my stock ROM because of the virus and gps so i search many forum but didn't find anything so I download another ROM from the same person and site but when I install it just like I should do it it gives me error 7 in recovery, so search that on YouTube and found a way to solve it by adding twrp recovery but when I follow the guide it flash wrong recovery into my device and now even in my backup I don't have any network signal. Probably it would be my fault not the one who guided. So
I have no network signal
