If you are still on the stock rom, you are going to need to flash the stock wifi modules.

Download the default kernel files and flash the wifi modules zip in recovery.

Problem with custom rom

Hello everybody, my device is a Samsung Galaxy S Duos S7652.
I am new at this whole rooting thing, i did my first rooting to be honest yesterday and i chose PMP Ultra custom rom, because it was the best rom for my taste.
Unfortunately i didn't know about baseband compability , and my baseband version was s7562xxlj3 , and now my phone cannot receive or make calls.
I need help, what do i do??
I cant even find my original rom so i can install that, or even a custom rom that supports my baseband..
Can you please help me?
Best regards, Alkis.

I think you are mixing some definitions.
Rooting is providing root capabilities to the phone, this is a standard operation in the *nix world.
Selecting a ROM is formatting the whole system and put a new one and you probably changed the kernel (hence the baseband problem).
Fortunately the phone is not bricked (unable to boot), so my recommendation is try to check if there are other kernels/ROMs compatible and change it.
Fortunately this showed while searching: http://forum.xda-developers.com/showpost.php?p=42182649&postcount=1708

I would recommend either restoring a NANDROID backup in recovery and if you don't have a backup I would recommend searching for your devices firmware here http://www.sammobile.com/firmwares/1/ and then flashing it via Odin. Let me know if you still have questions I'll be happy to help you out.

Hey man, could you share with us some details how you solved the problem? What firmare you flashed, did you used some custom kernel etc?
Thanks.
best way is too..
Reflash the stock firmware by going into download mode by pressing voldwn+Home+power and connect it to pc only when u have d samsng drvrs or kies installed on pc and firmware file too..

That's a bit of overkill if they just need the modem, unless it's not been separated out of the original full firmware to flash separately, or you need to update the bootloaders.
To dosadnik2001: Which firmware you need depends on which region the phone is from typically. Sometimes other modems from other firmwares work on unlocked phones, but best to stick with what you know should work right first.
What I do not understand is how the baseband firmware and the custom ROM are related?
I've found some post about changing the baseband firmware and there they say that the ROM doesn't care about the baseband, so you should only change it if there are some optimized baseband that can make your network coverage better. On the other side, I found several post claiming that certain ROM is not working because of the baseband firmware version.
Flashing firmware that is not for your region is again questionable for me. Doesn't this going to mess up somehow the microwave part of the phone and you can have some issues with the network carrier eventually?
Thanks.

*sigh* You realize when you say "I downloaded this..." without providing what "this" is is pretty useless for us to help you troubleshoot?
What update WERE you on before you started modifying the phone?
What did you download and install?
What modem / baseband version is installed?
Wifi and phone functions are most likely not working because you either downloaded the wrong thing or didn't follow the installation instructions correctly. Typically this would be because of mismatched modem and kernel or there's a patch that needs to be installed.
Usually I would just say install the newest stock firmware (4.4.2) through Odin, but depending on what update the phone had originally and if you plan on continuing to customize your phone, it might be better to stick on an older system as the newer ones really lock down the ATT version.
Long story short: Help us help you. Provide ALL the details about what's going on and we can probably get you fixed up easily enough.

I337MVLUFNC1_880525_REV06_user_low_ship_MULTI i installed this rom , i was on kit kat 4.4.2. and i installed gummy rom which did not work , then realized i lost the @#$#@% backup here is what it says under about device: model sgh1337m
android version -4.2.2
baseband -1337mvluamdj
kernel version 3.4.0-517283 [email protected]#1
build number - jdq39.1337mvluamdj
selinux status - permissive
i have data but no wifi and cant dial out . wish i was more careful with my stock rom lol. i dont think the kernel is right ? Think gummy rom did something to it . can i fix or can i get stock rom ? I am on rogers carrier and need canada rom or to fix can you tell me if there is a patch .
I just realized that samsung posts their factory roms so i am thinking to go back to SGH-I337M RWC I337MVLUFNC1 4.4.2 . which is what I had there before , Do i need to do anything special before i flash it , this file is .zip so what is the best way to flash ? ROM Manager?

Updated to 4.3 EFS went from v1 to v2 and can't get signal on custom roms

Hello!
Phone Gt-i9300
So i was happily using omnirom for 1 year until my motherboard died last week
so i ordered a new board. i installed it, it was on 4.1.2 unlocked, and i decided to update it without making a efs backup! so dumb!
So i installed a 4.3 Stock ROM, no signal so i had to install
-Patched XXUFMJ9 kernel
- Patched BUUGMJ3 modem
So i can use my phone with no problems in STOCK....
BUT. I hate STOCK..
I have tried to flash omniroom 4.4.4, but it says unknown baseband, uknown imei.. i tried installing omniroom and then installed again the patched modem buugmj3 and ofcourse nothing happened...
So.. my question is.. Am I forced to stick with this TouchWiz Rom? or is there any way for me to do something to get omniroom detecting my signal?
Oh something i was forgeting.. before i updated to stock 4.3... i installed first omniroom.. but i decided to update to stock 4.3 because i was getting signal but it could take 1 HOUR for the phone to get the signal.. and from there signal would lose at any moment.
anyone? i read the FAQ and did this
Q9: I'm sure I've correctly flashed an SGSIII ROM with the right CSC for my network but why can I still not make calls?
If your phone was running an Android version less than v4.3 before you flashed a new ROM then you may need to install a patched modem and, if you upgraded to a newer stock ROM, a patched kernel too such as the zuluman modem FW/kernel. You will usually not need to install a patched kernel if you install CyanogenMod or a CM-based ROM. A number of kernels and modem firmwares patched for Android 4.3+ are available here.

S2 Wifi Problem?!?!

Hi guys, I was wondering someone could help me as I am noob in this area.
The thing is my Galaxy S2 I9100 was normally running 4.1.2 android and everything was great until sudden wifi connectivity problem. My Wifi won't turn on, keeps turning on but then just keeps it off and trying on and on. I used Google to help me out and there it says it has to do something with bad kernel .They mention some Siyah kernel as a solution.As I am already familiar with flashing, installing custom ROMs, I updated to CM13 (6.0.1) but couldn't install GApps through CWM 6.0.4.5 because of a small partition. Still my wifi problem occured, and I saw it has nothing to do with the ROM but kernel itself.
MY MAIN PROBLEM:
Can someone write instructions for a best package of KERNEL, RECOVERY and ROM that will fit together with no problems, preferably that Siyah kernel for my wifi problem and working partition for increase in internal storage for apps so i can install at least nano GApps?

Hi,
If you updated the ROM, then you also changed the kernel as the kernel comes with the ROM.
Try going back to full stock ROM, flashing via ODIN. This way, we can diagnose if it is hardware problem or software.

Does your device have a valid IMEI? If it doesn't, your efs partition may have been corrupted.
If it is still valid, it is likely that you are experiencing hardware failure. Switching between ROMs or Kernels will not help in this case. I'm afraid I am out of ideas other than replacing your device or buying a new motherboard.

I dialed *#06# and it says my IMEI is : 353824059632022 / 01 Is that valid IMEI?
Can I try this for myself: http://www.selftechgenius.com/how-t...nvalid-argument-in-all-samsung-galaxy-phones/

Your IMEI is valid.
That last thing I can think of is to try this kernel (even though I said that changing might not make a difference):
[PhilZ-cwm6][i9100/P] Stock Kernel+CWM6+Root+exFAT+NTFS-MS3
If the issue still exists, you have a hardware problem.

Although re-flashing stock ROM did good job (if wifi somehow stops,just need to restart phone), with this kernel for JB now I have no problem. Thanks mate !
Hello everyone i faced the same problem and solved it by an app called wifi fix which is made by amid M Geha
