Hi All...

My phone's WiFi and bluetooth don't turn on anymore. The problem started nearly 1 month ago when I decided to root the device and try out some custom ROMs... Even battery lasts 5-6 hrs only with minimal use... :(
Now after a lot of research and googling and trying out various possible solutions I have decided to surrender... :arghh:

I need advice whether it is possible to replace the wireless connectivity IC of the phone.
If yes, should I do it in a local mobile repair shop or samsung service center?

Any help is appreciated...

Thanks for reading..
 
Which rom have you installed? Provide us the link. Also check the thread if anyone has reported for same issue.

It can be a software issue and you dont need to replace IC for that.

Try installing other custom rom and check. If not. Try to flash Stock rom again and check if WIFI and Bluetooth is working.

I have tried out numerous ROMs from the xda forums... Eg. Prism Barebone, Arrow, LiquidSmooth etc... Currently I'm running OzcanROM... Mostly tried everything from here - http://forum.xda-developers.com/galaxy-s4/i9500-develop
None of the other users have reported such an issue... And those who have reported such issues have pointed out that removing the battery and inserting it again fixes it for them. But for me nothing works...

I even tried flashing stock ROMs, flashing different kernels too.. But still nothing works.. :(
 
Hmm... I had tried the Samsung service center at vizag... Initially they told that they will try to load the software and since the phone is no longer under warranty, they will charge 200 for it... I agreed to it and they started the procedure in front of me... The support guy struggled with getting the phone into "download mode" itself.. He was not aware that the "debugging mode" needs to be enabled else phone won't go into odin mode... By that time, I was convinced that I have come to the wrong place... :confused:
Then after 10-15 mins of struggle, the support guy suggested that I go for complete motherboard change and it would cost around 9k... I then walked out of the service center...
I have not tried the bangalore service centers yet.. But I don't have high hopes from Samsung service... Hence wondering if any other renowned mobile repair center can just replace the IC... whether that would even be possible...
I then found online - http://www.parts4repair.com/wifi-bluetooth-ic-for-samsung-i9500-galaxy-s4/

Since you said the problem happened after installing Custom ROM it is most likely software related. Or Maybe you have installed a new app which is causing interference.
In the meanwhile try this. Go to accessibility and turn all software to 'off', none should be on. Go to security>Device administrator all apps should be unchecked. Go back, open 'Apps with usage access' no app should have usage access. Restart your device and turn on Bluetooth.

No.. I did not try it.. It was too much hassle with not much probability of success.. Hence sold it off..
