So I was trying some new roms (CM11, temasek, etc) today and I got an error when flashing an old 4.1 samsung rom (I was on 4.3 official yesterday).
Now my SIM card is not recognized. It says "only emergency calls" and nothing else. I don't have cell signal at all.
I tried taking out the SIM and putting it inside again and factory reset in CM. I also tried flashing again the 4.3 samsung unlocked rom.
I'm downloading right now the 4.3 official rom from Vodafone (my carrier), in hopes that will fixed it with ODIN, but just to be sure I'll ask if anyone knows how to fix this issue.
Thanks!

If flashing the stock 4.3 rom with odin doesn't work then you'll need the backup you made of your efs folder.

My Galaxy S3 GT-I9305 LTE was running Liquid Smooth 2.37. Recently I lost notification and phone ring sounds and now I have lost baseband and I have no cell signal.
In the phone's 'about' section the baseband field is empty. Android version showing is 4.3.
I'm not quite sure what I did wrong, first to try and get back the sounds and then baseband, I have been playing around with various custom and stock ROMS and kernals to get full functionality back.
I've read tons of help posts but nothing works.
Here's a few of the things I've tried with results in brackets, used CWM recovery to restore working backup (failed 'unsupported file' message),
reflashed kernals (neither Boeffla nor yank555 have worked, wipe/data restore in CWM (it still takes me back to 4.3 with no baseband).
I thought I'd re-flash back to the phone's original stock ROM using Kies, but the weird thing is Kies doesn't restore, it upgrades to the latest 4.3 ROM which fails to restore baseband.
I wanted to send the phone back to the 4.1.2 it came with or was it an earlier ROM? I can't remember as I didn't note it down, I bought the phone second hand, it arrived loaded with a stock ROM for Australia's Optus network. I promptly rooted and flashed the phone to Liquid Smooth and the phone ran fine for months on the 2 Degrees Network in New Zealand.
Anyway, I must have tried reflashing a dozen stock roms I've found online using Odin. Some of them partially work, I get sound back, (it seems only the 4.3 ones work, with the german I9305XXUEMKC reliably loading - it even gives me a NZ english install option) but don't restore the baseband
. All the ones I've found for Optus are rejected, I get the 'unsupported device' or status 7 error in Odin.
So I decided to flash one that works, install cwm, root the phone and try installing different baseband kernals to fix the (probably corrupt) efs.
But I'm going round in circles trying to root the phone. Using CWM, supersu shows as successfully installed, but when I boot into the OS root checker shows my phone is not rooted. Knox seems to obstruct every attempt I make to disable it as well. I keep getting these 'knox stopped etc...from working messages'.
I'm sorry if my description is a bit confusing, I'm happy to clarify anything.
I'm at my wits end. I want to try everything before I have to ship the phone off to a repairer who may charge me hundreds of dollars to fix the phone.
This is I9300 not I9305 Q&A
Use the report button and ask a mod to move to the correct forum .
I can offer no help as i fail to understand the post .
As said before you are in wrong place and are not giving us a clear question to answer. If its a root problem there are fixes for it. Status 7 error is discussed in many threads. Flashing MG4 modem fixes efs problem. Downgrading causes problem. Learn to search before making a thread.
Hi guys,
I've ordered a new, unlocked i9300 from eBay, and I had some adventures with it:
I've unpacked it, inserted my SIM, powered it on, and found out that the phone always thinks that I'm roaming. Instead of trying to understand what's going on, I though: "I'll just install CyanogenMod and everything will be good".
I've installed CyanogenMod 10.2 (latest stable build), only to find out that my SIM is not being detected at all. It says that Baseband is unknown, IMEI and related are unknown as well.
After trying lots of stuff, I gave up and decided to return to stock ROM (4.3). While trying to do that, I bricked my phone, and the only thing I could do is enter Odin mode.
After reading dozens of tutorials and trying lots of stuff, I ended up flushing GT-I9300_mx_20120329.pit, and that unbricked my phone.
I successfully flashed Android 4.3. This version detected my SIM, displayed the Baseband/IMEI, but it didn't connect to the cellular network. I could scan for available networks, but when I chose my network manually, it said "Selected network not available ".
I tried to flush alternative modems, but all it did is making things worse. Usually it made the phone behave like with CyanogenMod, i.e. Baseband/IMEI are unknown.
Again, after trying lots of stuff, I tried to flush Android 4.1.2. That made no change until I've stumbled on this thread. Flushing Patched_Modem_I9300XXEMG4.zip made my networking work again, and restored it to behave exactly like it did initially. Again, the phone thinks that I'm roaming all the time, but at least it works.
So currently, I have two issues:
My phone always thinks I'm roaming. Is there a fix for it?
And more important: currently, I cannot install anything other than Android 4.1.2!
Could you please shed some light on the situation? What happens with my phone? Why does it think I'm roaming? Why does the SIM work only with Patched_Modem_I9300XXEMG4? How can I make other ROMs (e.g. CyanogenMod) work?
Thanks, any help is much appreciated!

When the phone gets upgraded from 4.1 to 4.3 your efs changes from efs v1 to efs v2 sometimes this upgrade does not go smoothly (as in your case) so then you need to always use a patched modem from version mg4 onwards (not a normal one) if you flash a rom which changes the baseband to anything less than 4.3 then it will not work.You need to keep on mg4 or later to keep signal and because your efs is not fully upgraded properly you need to always use a patched modem and preferably kernel as well.
I am not sure about the roaming issue but if you try patched modem and patched kernel together that might help.Take a look here for some patched modems and kernels and remember you always need to use them >> https://drive.google.com/folderview...sharing&tid=0B6MIUd7HJudAbU5YaGkzOUowMG8#list << You should also be able to use 4.3 roms as long as you use the patched files above ie baseband and kernel.
In general, It would be great if I could use CyanogenMod 10.2.
Should I proceed in the following order? Flush CM -> flush patched kernel -> flush patched modem.
Which of the patched versions should I choose?
Also, what do these versions change? What functionality was patched in these files? Can I read about it somewhere?
Thanks for the help.

No the kernel will only work for 4.3 roms not CyanogenMod roms but the patched modems will work.You can try flashing CyanogenMod then the patched modem but CyanogenMod does not include a modem so whatever modem you where on when you flashed CyanogenMod you will keep.

I tried installing CyanogenMod, then flushing some of the patched modems you've linked. Unfortunately, nothing changes - Baseband/IMEI are always unknown.

You mean flash not flush.
Also you should be careful to by things like this off ebay, There is a very high chance you brought the phone broken like this but did not notice straight away.
Don't hang around on 4.1.2 as you might get SDS.
Upgrade to 4.3 stock of higher using custom roms with a patched modem of mg4 or higher as stated by tallman43.
Read here for what you or the previous owner has done. Also on stock make sure your csc is correct.

If you cannot get it to work you need to take it in for repair. Make sure it works on 4.3 before paying.
Hi, first of anything, sorry for my bad english, i'm brazilian
So, a few days ago i flashed cm11 on my cooperve (S5830c), and then, the Galaxy Y modem. The phone boots with the SIM, recognizes it's operator (VIVO), but the signal bar keeps empty, and when i tries to make a call, it just shows me the message "Mobile network not available". If i dial "*#06#", the phone shows me my IMEI, and it is the same as the impressed on the phone's back.
Can anyone help me? I don't want to go back to stock, but it's just impossible to stay with a phone that don't make what it was designed for
@.Create, This post will be merged probably,since there is an ongoing discussion topic for all of Cooperve devices on CM11 nightly build.
This is a well-known problem with this ported CM11 ( please read the first page change log) Be advised you put your device in danger by flashing wrong base band/modem into different device. Your EFS partition, which, help you to keep your IMEI safe from getting corrupted might be in danger ( back up with Galaxy toolbox is recommended) and for the record mate, whoever claimed that they did upgrade their base band ( even the correct region) through Y modem did misguide you as developers never mentioned it directly. You could always back to custom GB-based roms with stock kernels, after flashing back to your latest confirmed firmware. ( even some custom kernel might damage your EFS )

@ehsanotaku Thanks for the reply bro :highfive:
Yeah, i know how to go back to stock, but i just don't want to, because android 2.3 is so outdated.
Some members have been successful at flashing Galaxy Y modem on their cm11 cooperve, and that's why i tried to flash it too. As my phone recognise my SIM, i Thought the problem could be just on the settings, or something like that :silly:
Edit:
Managed to get it working, thanks to @flexton
For anyone interested on what i did:
First, i did a nandroid backup;
Then, i went back to stock;
Booted stock one time, then flashed Galaxy Y modem;
Wiped data, cache and system on CWM;
Restored the backup :highfive:
I have a problem with a Samsung Galaxy S3 (GT-I9300) which belongs to a friend.
He wanted Lollipop on the device so I flashed an Unofficial CM12 from here - http://forum.xda-developers.com/galaxy-s3/development/wip-cyanogenmod-12-t2936990
However he seemed to be experiencing some bugs with the ROM so he wanted to revert to stock ROM until more stable builds arrived.
I flashed the stock ROM 4.3 obtained from SamMobile but on this the SIM wasn't working. Same results were obtained by official 4.0 and 4.1.
I finally decided on the official CM11, grabbed the latest stable build and tried flashing it. But now the ClockworkMod recovery returned 'Status 7'. Repeating the process with device id verification removed gave 'Status 6'.
To get the device in working condition I had flashed Korean Service ROM by Samsung. This is working with the SIM card with a few bugs.
One other curious observation was while copying the CM11 to the internal memory. The copy window was dismissed before the green copy bar reached the end. I had to flash it with an external SD Card which seemed to have normal copy process.
This entire process has been repeated on a different PC with all fresh downloaded ROMs but gave the same results as before with the only exception of SIM recognition but no signal on CM12.
Any help would be appreciated to get the device working normally.
Hi,
but "SIM wasn't working" means that your phone is like a phone without SIM?
I had the same problem in the past with my old i9100 and in that case the problem was the non correct baseband (radio) and RIL (Radio Interface Layer).
If this is your case, you can try to flash the correct modem (it depends from your model and firmware version) from recovery or using Odin. First backup EMS folder (IMEI folder)...
I had the SIM inserted. And the modem is okay because the official firmware was of my country.

I understood that the SIM is insered but the phone is without signal as you haven't... so probably the problem is modem or corrupt EMS folder...
Now you are running stock firmware or CM?
I had my s2 hard bricked and now i got a new motherboard for it, the thing is that on all stock roms (2.3 and 4.1.2) the phone works perfectly but all the custom roms 4.4 5.0 6.0 the cellular does not work, it gives me no service, tried flashing modem from cwm but no change.
i also tried different recoveries etc but custom rom no service
sometimes in custom rom imei used to be blank but it comes back after reboot, in stock no issues at all
any idea what im doing wrong or is there something up with the new board?
thanks,
Update
I was searching and I read somewhere that installing NeatROM by Sale will help, i downloaded and installed it, the good news is that cellular works and i have full 3G access.
Question: How to proceed further?
i could experiment but the thing is that if i flash a non-working rom (no cellular), i will have to flash stock from odin and start all over again
any ideas?
Update 2
i tried NeatROM and it worked perfectly, then i tried installing slimLP and boom, no service again, this time,my IMEI was blank too, so now i'm flashing stockrom again.
any idea anyone please?
