[Q] [I9500] Have generic IMEI and not able to connect to network

Hi,
I had installed the CyanogenMod 10.2 available in the original android development section on my I9500. I flashed it in the morning. everything was working fine except camera till afternoon. Suddenly on afternoon i observe that my phone has entered into emergency signals mode and was not connected to my mobile network. First i thought it was signal problem but upon reading found out that it is IMEI getting changed problem. I have installed Stock ROM again to try if it solves the problem but sadly it doesnt .
Anyone out there faced the same issue and can help me?
Thanks

I have an Indian model I9500 . I tried flashing Omega Rom before trying CM. For Omega ROM i flashed XXUBMG9. After that i flashed back the Stock firmware I9500XXUAMDE_I9500ODDAMDC_INU. Then i flashed CM. CM worked fine for half a day. Then it failed connecting to my network.
With the method you are telling i flashed my stock firmware modem first, but it didnt work. Now i flashed XXUBMG9 and it worked.
Can't i go back to my stock firmware modem now? Am I stuck with this modem ?

you still on the first old firmware for India (MDE).
you can take ota update and then the modem will be replaced. or flash latest Indian firmware (MG5) and you will be on full stock.
PS. i guess that modem does not affect warranty.

MEA firmware came with DDUBMEA modem. try to flash this modem alone as "phone" twice http://d-h.st/c9i
any way these are all INS firmwares http://www.sammobile.com/firmwares/1/?model=GT-I9500&pcode=INS#firmware

I tried flashing MEA modem twice all other Indian Modems twice and nothing worked. It is only working on XXUBMG9 modem. I am really stuck on this modem.
Does anyone has a theory of why this is happening? Omega ROMv14 wanted flashing this modem as a prerequisite. I had flashed this modem before flashing Omega. Then i went back to my stock and flashed CM over my stock ROM. CM wasworking fine till sometime , then it started to drop the signals and later i realized i lost my imei. If i flash back the MG9 modem the i get the proper my phones imei and network connects. But for all other modem of india it just shows the generic imei and doesnt connect to network.
Can anyone help me postmortem this case and tell what went wrong where?

all failed

WiFi won't turn on (stock non-rooted) i9505

Installed fresh stock rom via odin and now my WiFi will not turn on at all
It was working fine earlier today and now it just won't work.
Help me please.

Nevermind... Just flashed the stock firmware again and now it's working
mods please close this.

Is that the only working solution known?
I'm having the same problem and did some searching and it looks like the only way to fix it is to reflash stock ROM.

[Q] Why doesn't my WiFi work on new ROM builds?

I have a N900W8, and most ROM builds are for N9005.
I have never had a problem flashing N9005 builds, and all radios working fine, until I tried to flash Audax 11 (running Audax 10.8 now).
After flashing, during the initial setup screens, the WiFi toggle doesn't respond at all. Even if i skip through the rest of the setup, WiFi does not turn on at all.
I tried flashing XNOTE 21, and had the same problem.
Anyone have any ideas?
Baseband is N900W8VLUCNB7, if that matters.

May sound stupid but try flashing a full stock rom package via odin and check if it works with stock roms. That would be the first thing I'd try. Maybe some rom you tried included a modem/baseband that it causing the issue. Flashing back to stock and then switching to another rom again may help.

Flashing stock ROM won't help, and OP is correct. There are some ROMs indeed where WiFi just stops working. I flashed a ROM like that few days ago, I won't name it because of whatever reasons, but it is considered one of the most popular ROM for N9005 and N900T or some model and can be found under T Mobile section, and after flashing the ROM my WiFi just wouldn't turn on. I don't know what was the reason, didn't care to be honest, but then I saw that there are some flash-able zip packages which fixes the issue, again, didn't care to flash those so called fixes.
So OP might wanna look for one of those package for the ROM he is using.

WiFi issue (stuck on turning on)

Hi guys. I'm having a problem with my WiFi. It will often be stuck in trying to turn itself on and when it does switch on, it can't connect to any WiFi. I've tried rebooting my phone, flashing stock Samsung rom, re-rooting and flashing different custom roms but none of it seem to work at all. I'm currently on temasek v15.6 and using N9005.

Anyone has any idea about what may be wrong? I read somewhere online that it may be hardware issue since the radio chip houses both the WiFi and Bluetooth. I am able to use my Bluetooth without any problem so I am quite sure it isn't the radio chip problem.

What 'stock samsung rom' did you flash?
Did the bootloader and modem update?
As a last resort i'd try it with a pit file to repartition your phone.
Sent from my SM-N9005 using Tapatalk

I went to use the latest Samsung lollipop from sammobile. It changed my baseband to that version of lollipop though. What's a pit file and how is it done? BTW, I flashed to stock using odin.

This is the stock I was using. The PDA version is N9005DXUGBOF1 and the CSC version is N9005OLBGBOF1. Lollipop 5.0 (Singapore).

I've tried the method that was being recommended but still having no luck at all with my WiFi.. Thanks anyway.
