[Q] Selected network not available | Galaxy S3 I9300 - Galaxy S III Q&A, Help & Troubleshooting

So basically I have a 4.3 stock rom on my S3 (International) and I tried to flash Blekota Note 4 rom but when i choose an operator its says "Selected network not available".
I tried it with Blekota S5 rom and same thing happened.
At the first time i flashed each rom I didnt have any signal at all but that i flashed 4.4.2 modem from some youtube video I saw and there was signal but Emergency calls only and the "Selected network not available" when I choose an operator.
I have no idea what I should do that will make it work because i like it better with those roms.
What should I do?

Problem is you screwed up your efs folder. First, I suppose you loose your device serial number. Second, you probably flashed modem with Ariza patch.
Now you need always use patched modem and unsecured kernels. Or repair your efs via box, or backup.
Flash CM11, CM11 dedicated Boeffla kernel and that modem you have used previously. Or download any modem patched with Ariza's method.
If it's work than you can try cm12... But always with Boeffla (or any kernel which didn't check modem integrity) and this hacked modem.

[Q] SHould I change CSC to my original UK provider

Hi
I'm just wondering if after flashing a new custom ROM (or indeed I started to mod my own rom from Wanam's de-odexed latest stock rom) should I flash my original CSC from 3Hutchinson UK (H3GALE4) or stick with the latest unbranded UK CSC? It's still unclear to me precisely what the CSC does?
Surely it is the radio/modem version that determines connection speeds/efficiency of the modem etc? Or could the CSC have special 3 mobile firmware for getting better connection with their network? - Or what I suspect is that it just loads the 3 network boot screen and installs the 3 app?
Thanks

Afaik csc file determines the country code and what apps are to be installed per country that samsung assigned, like bbc player for the UK. But it`s not that important to be honest.
Thanks,
So only the CSC is carrier specific? Radio/Modem is purely just firmware for the radio and modem? I ask because in the UK 3-Network transmit using UMTS (not GSM) on 2100MHz so I wondered if there was anything that could optimise this. It seems to me that ALL 3 phones in the UK use the NELE4 modem - is there a reason for this?
I'm on 3 in the UK had it for a few weeks now on le8 and le4 modem rooted and changed the kernel to siyah but don't want to flash a custom Rom yet for the csc reason and seen in a few places people losing imei number too is that them just being completely dumb tho and flashing incorrect roms etc?

I had read the same although I took precursive efs backup and immediate image of my initial stock. I've flashed through some nice ROMs but recently decided to make up my own from one of Wanams deodexed stock roms. However I have really liked the Omega rom so I may roll with that, but I have been reflashing the CSC to 3 H3GALE4 thinking perhaps it improves things for 3 users??? But I reckon moreliekly just provides the 3 splash screen on power up.
My interest in modems and/or CSCs is that my primary reason for the sgs3 is not so much a phone as my home internet provider as i live in v rural area yet with an anttenna I can get above 5mb/s whereas my land line can barely provide 1mb/s. So any modem/mod/hack which specifically improves this and perhaps even the software/driver behind tethering is what I'm keen on learning about.
Great phone though.
Amazing phone couldn't want more gui is so smooth I have from some where got on my internal sd a efs-backup.zip so I will back that up and try checkrom worst comes to I send it back
Sent from my GT-I9300 using xda premium
Well I tried Checkrom and that too is really really good. Prior to flashing a new custom rom I followed the instructions of flashing back to original stock and triangling away which worked absolutely fine too.
Yeah already tested triangle away works wonders with siyah kernel it dont even need to restart the phone great work on that chainfire

I'm sure whether or not I get terrible 3G speeds without the 3 modem or not
Poor speeds is often modem related try BULF1.
CSC can be copied out of original rom and replaced in a custom rom before flashing .
System CSC folder and CSC version text .
CSC is not required for a phone to work and is only a list of local area network connections on stock .

How weird I looked on kies this morning golf lf1 csc and lf6 Rom just upgraded running smooth had to re-root tho which was expected

Been running Turkbey Custom ROM for a month now, and 3 mobile CSC was not available in this ROM but it has had no effect on anything and everything I do, and installed bbc iplayer and 3 network app automatically, so I agree CSC is not that important.

I've been doing some tests and I am *begining* to think that nele4 modem is the best on the 3-network in UK. Will update after some other tests.

Thanks for info. I'll try BULF1 in my little ongoing tests.
Does anyone know of a custom mod/app that replaces the stock "tethering" software with a better one? I ask because I can get 10Mb/s mobile data connection on the phone but when I tether my laptop, that will only reach 4-5Mb/s. I want my phone to act as good modem router - seems the stock one isn't as good as it could be??
I'm on 3 UK, using Omega10, all modems included with Omega worked well, you can try flashing any modem, I'm currently on lg6

Just to update u guys pro efs will backup your efs folder to your pc no problem I recommend using this before flashing too much

I've been at sea for anumber of weeks so I have only just caught up with this thread again. I have tried a number of modems (and given them a few days to "chill out"). All though I still do not have any quantative proof it *seems* as if the original NELE4 modem works the best - by best I don't mean connection speeds but in the UK without moving location I seem to get H+ more consistently whereas other modems would *seem* to jump between 3G, H and H+ more randomly. These are only thoughts - my observations may be completely wrong. WOndering if anyone else has noticed similar?
Even if I am not in the UK, I would like to confirm my understanding of CSC as I just found out that my phone's status is CSC: unknown after I flashed the newest 4.0.4 update for my region (TH, I9300T).
As I understood CSC does not impact the phone a lot, only the region specific play store settings and networks. Currently I face no problem with the phone at all, normal reception etc., hence would you still recommend flashing the correct CSC to remove the "unknown" status or just keep it like it is and wait for JB later? (I am aware that CSC flashing will format my phone)
Thanks

I really am not the best person to answer this I am afraid although does reflashing your CSC really format the phone?? I thought you could use ODIN to just reflash a CSC and leave the modem and FW intact but I may be seriously wrong so don't do it on account of what I've said! Hopefully someone will clarify.
As has been said by others on this thread (many thanks) I really doen't think the CSC matters that much at all - the only difference I notice between the 3UK CSC (H3GALE4) and a non-branded UK CSC is that I lose the Three logo on boot and BBC Iplayer and Twitter App aren't installed.

[Q] Sending I9100 back to Samsung. What do I need to do?

Hi everyone.
I need some help with my I9100. I am not receiving any reception on any networks so I have called Samsung and will be sending the phone back for repairs as the phone is still under warranty.
I was using the SuperNexus rom in the android development section. The phone was working brilliantly with this rom and suddenly stopped picking up any network after weeks of using this rom. I hadn't changed the radio in this time either.
I am guessing I will have to unroot the phone and flash original samsung firmware again.
Can somebody point me in the right direction please. I need to know how to unroot my I9100 and need to know which firmware I will need to flash.
Thanks in advance.
Download your stock firmware, and flash using Odin, use Triangle away before flashing

Thanks for your responses
I flashed the stock firmware (I9100XWLPY - H3G UK) and used triangle away to reset the flash counter.
I've re flashed supernexus build 5 after rooting and used getril because the baseband and and ril didn't match according to GetRIL.
my baseband is I9100NELP4 and it recommends me to flash I9100XXLPX; I9100NELP4
now it is matching but it still doesnt pick up any networks. I've tried O2 uk and Three UK. I am on the Three network.
My IMEI *#06# matches the IMEI behind the battery. However the S/N does not match from settings and behind the battery.
Is there anything I can do before I send it back to Samsung for repairs?
Make sure your flash counter is 0 ( check in D/L mode) and have a completely stock unrooted firmware.

i9100p Unable to flash any modem.

Hi all,
A colleague of mine asked me to help him with this phone (i9100p) because suddently he lost his IMEI number and in the phone settings the baseband shows as unknown. I have tried many things to fix it but nothing seems to be working. I cannot even flash any modem in CWM as it gives these error:

Any ideas what could this mean and what to do about it?
I got that same code( I think) when flashing modem ( ihave gt-i9100) and only option was to flash another kernel. I think I used philz but since u have the P version read up first. Good luck

Flash dorimanx or syiah kernel then flash modem . its no diference betwen flashing kernel,modem or ay other mod all flashing the same

Well, actually I was trying that on Syiah kernel...
Have you tried radio cleaner script? Is a "p" so I can't give a link. Look about for a script for your model and flash that first then modem. Does he have a imei bk up? Prob need that too. If not service center job.

READ the faqs and guides before flashing .
Is your IMEI correct of not restore your backed up EFS folder .
No EFS backup as per the instructions then you require a service centre repair .
Read the faqs and guides critical to understand post one and two BEFORE flashing
before sending to service center you can try installing a stock rom from sammobile via odin. this sometimes recovers the imei and network connection. you need to install a stock rom and reset your flash counter anyway if you want to keep your warranty
Make sure to flash a recent rom that uses mg2 or mg4 baseband.

What modem did you install? if you installed XXEMG4 it would have formatted your 'efs'
Check your IMEI by dialing *#06#
for more info check this link
The modem does not format or erase the efs folder. It alters the format so older modems can't use it. That is why if there is no efs backup prior to using mg4 or mg2 modem. It is impossible to revert to older modem

Its actually the rom not the modem and yes, ultima is based on a version of the rom that alters efs.

Not sure what you're asking.
Read general > Sticky roll-up thread > "IMEI / EFS - Know this stuff"
Everything I have read, but if you want to return a Nandroid backup, if you will?
It's nowhere
if your nandroid backup does not use an mg2 or mg4 modem than it will not restore your network. if you want to fix your phone go to sammobile.com choose any rom that uses mg2 or mg4 modem. flash it with odin. if that doesn't work take it to a service center

[Q] Galaxy S3 "Not Registered on Network" Problem

I am using an international version of galaxy s3 in Pakistan. my previous stock ROM was I9300XXUGMK6 which is UK based and it was working fine in pakistan. Today I downloaded I9300XXUGNB6_I9300OJVGNB3_PAK ROM from sammobiles and flashed the ROM on my phone using Odin. After installing that stock ROM my phone is giving error of "Not Registered on Network" whenever i try to make a call. my IMEI number is same as printed on the back of the phone. signal bar is also full. when I manually search for networks then it also shows me all the network name in the area and when I select the network it give me message that network registered. but I could not make the call after that.
Plzzz help me....
Search and read there is no easy solution. Try a patched modern and kernel, which are usually needed when the efs has been broken.
Thanks
