Question on WiFi not working immediately on some S4 but working on others

How is it that some i9505 can just flash ROMs such as Omega and get properly working wifi whereas I and many others still have to flash the modem/wifi fix to make it work? And apparently i9500 users don't have this problem. What seems to be causing this issue?

Cannot turn on Wifi and Bluetooth on LG G2 D802

Hi to all LG G2 Expert and to all Mobile Expert in XDA.
I have LG G2 D802, the main issue is I cannot turn ON the WiFi and Bluetooth.
I've already done the following and still the Wifi and Bluetooth doesn't work at all:
- Flashed (2x) stock firmware (D80220A_00.kdz, D80220B_00.kdz)
- Install custom rom (Cloudy Pro II 2.2)
I need your help, please give some advice and instruction on how to fix this issue.
Thank you in advance.

I have the same problem too!
Have you found a solution to it?

I have the same problem too!

Same here.
anyone got anything?
sheer terror.

Quite similar problem here.
I'm on Cloudy G3 1.2. My wifi is working fine, but impossible to turn on bluetooth. It stays on "connecting ..." then goes back to disconnected.
I think this is a hardware problem because it wasn't working either on stock 4.2 nor 4.4

I had same problem when Wifi/bluetooth MAC address are unavailable. It keeps turning on and automatically turned off after a certain of time. I tried to flash stock rom (4.2.2 & 4.4.2) and kernels as well (Cloudyfa & Dorimanx) and still the same result. In this morning, it's suddenly connected to my network and I am able to browse the net when I connected USB OTG to it. I was soon restarted the phone and the issue comes back, poor me . Now, I have no way to make it working again. Any suggestion on fixing the problem? Thanks in advanced!

I have the same issue.

Same here

I am definitely sure it's hardware related problem. I was so lucky when wifi + bluetooth could be turned on for few days but I need to turn both wifi + bluetooth on to get wifi working, the phone was pretty hot at that time and it only worked when I plugged my phone to wall charger at 100% battery. Sadly, it's not working now after many attempts. Need hardware replacement, I guess

it may be app lock or something
try disabling any app ,ocker or something like that, those things sometimes can interfere with the working of those two stuffs

All these things can cause and effect your situation and have to be considered before warranty repairs

GPS problem after flash rom then back to N3 S5 stock :S !

Hello everyone, so I will explain the problem, yesterday I flashed a rom galaxy S5 on my Note 3
(http://forum.xda-developers.com/showthread.php?t=2771454) however she was not stable enough,
so I came back to a stock rom by putting a theme S5, so far so good but just now in the car I
decided to put the GPS and nothing, no signal the car was not moving on google maps ...
Do you have a idea where the problem could come??
Thank you very much!

Stop being lazy and do some reading on the S5 rom thread.

Reception issue / Antenna cutting out

Hey guys,
About 2 months ago I brought an i9505, it's overseas stock I think it had firmware for Netherlands? Anyway it worked perfectly fine in Australia. No issues what so ever. I recently though ok I really want to root my phone and install an AOSP rom. I flashed the 4.4.4 Google Play Edition rom located here: http://forum.xda-developers.com/showthread.php?t=2557353 I also tried out a few other ROMs but with every ROM I had this problem with reception dropping down to 1 bar randomly, then at times the antenna would be gone all together and had some circle with a line through it. Sometimes it comes back but if I leave my phone over night when I wake up in the morning I cant send sms's or make calls.
I don't know what im doing wrong ive followed the instructions corresponding to the ROM developers notes. I really don't want to return to stock firmware because that's the only firmware that currently works fine.
Cheers.

[Q] Cyanogenmod on USCC S4 issue

I had an issue where when I installed Cyanogenmod that my S4 was stuck in roaming. USCC tried for two hours to get it working but then filed for a replacement under warranty. Well I got this one running after trying many things. I used ODIN to go back to kitkat and followed this post.
http://teamuscellular.com/Forum/topic/2592-last-attempt-to-fix-stuck-in-roaming-mode-for-the-sgs3/
It worked and fixed the roaming issue and now I can use my phone as like before.
I want to use Cyanogenmod but what can I do to avoid this issue again? Also, where can I find other ROMs compatible with my device?
