Red face Wifi not work!

Hi all! I am a brazilian, sorry for my poor english. I have a GT-I9100 and used the 4.0.3 ICS ZTO official (LP7 kernel, LPF modem and LP4 CSC) until last week. The wifi started having problems (icon in the notification bar grayed out), not allowing the activation of wifi, even by settings menu. There are several similar cases on the Internet, including citing defective hardware (internal battery next to the wifi chip), which is not my case (i already checked internally). Always used CF-ROOT kernels compatible to root the phone. So as the wifi stopped working, i decided to test the Omega ROM V20 (JB 4.1.2). The phone is working better than my old version of Android, except that wifi still does not work. Because of this, i decided to install the version that came from the factory on my phone (2.3.3 GB ZTO, KE4 kernel, KE2 modem and CSC). And to my surprise, the wifi was fully functional!!! So i went back to Omega ROM V20 and wifi no longer worked anymore. In all exchanges rom, all wipes are made. Then i installed Catlog to see if i could find some clue about this defect, and the log related to wifi was this:

02-19 22:16:06.065 E/WifiHW (2421): ==========[WIFI] Station firmware load ===========
02-19 22:16:06.130 E/WifiHW (2421): ##################### set firmware type 0 #####################
02-19 22:16:07.260 E/WifiHW (2421): return of insmod : ret = -1, No such device
02-19 22:16:07.260 E/WifiStateMachine(2421): Failed to load driver!
02-19 22:16:07.270 E/WifiStateMachine(2421): DriverFailedState
02-19 22:16:07.280 E/WifiHW (2421): Cannot open "/data/.cid.info": No such file or directory
02-19 22:16:07.280 E/WifiHW (2421): ==========[WIFI] Station firmware load ===========
02-19 22:16:08.445 E/WifiHW (2421): return of insmod : ret = -1, No such device
02-19 22:16:08.445 E/WifiStateMachine(2421): Failed to load driver!
02-19 22:16:08.475 E/WifiStateMachine(2421): DriverFailedState


These lines are always repeating itself in the log since the wifi button on the notification bar is greyed out. Apparently it's a problem with the wifi drivers. In my phone the 2.3.3 is only that the wifi works, however, is pretty old now and do not offer the features that a JB version can offer. I ask the masters of this wonderful forum: is there any way to import the wifi drivers from my original version 2.3.3 to 4.1.2 Omega ROM i'm using now?

Best regards from Brazil to everyone!

Unhappy Conclusion: my wifi chip is DEAD!

Hello and thank you for the tip. But unfortunately i came to the conclusion that i have a hardware problem. First, i installed the leaked version (with no mods) for United Kingdom 4.1.2 (LSJ kernel, LS1 CSC and LS6 modem). With this version, the wifi is not greyed out, however not active (immediately the slide button back to position "0"). So i went back to version 2.3.3 where the wifi worked perfectly. Now the wifi activate, but not find any network and in a few seconds, turns off automatically. We made ​​all wipes in exchange ROM. My GT-I9100 has a little more than 2 years old an now my wifi chip is DEAD! At least the bluetooth still works! The deal is now expected to launch the Galaxy S4 to spend some money, because S3 is outdated. In Brazil, not worth sending fix this phone, even out of warranty (it can cost up to half the price of a new). I am very grateful for your interest in helping me!

Thank you very much!!!
