[Galaxy S II General] PunkOz:
Well, I've used ParanoidAndroid ROM since version 1.1 and someday the WiFi just stopped working. I always try to fix everything by myself before asking for help, I think I've only made 2-3 threads in XDA asking for help

Anyway, I tried flashing the ultimate kernel script cleaning, formatted both internal and external card, system, data, I formatted everything in mounts and storage section in CWM and after that I flashed a stock 4.0.3 ROM and WiFi still won't turn on.

I tried the Jelly Bean port by LastStandingAndroid before going from paranoid 1.5 to 1.6, I think the JB Port was the problem.

I'm really sad, this is the first time something like this happen to me since I bought my galaxy which was a lil over a year ago and I've flashed.. So many ROMs

I think my problem could be the EFS or PIT, not sure though. Thanks in advance!

Edit2: I've restored my EFS folder with a backup I made a while ago, I restored by copying the file with root explorer and replacing the EFS folder I had (IF I did something wrong let me know). I've tried stock firmware (Gingerbread) with a hard reset (Formatted everything in mounts and storage in CWM) and flashed the stock GB firmware and nothing. It just turns on "scans" and turns off again by itself, when I was in ICS It wouldn't even Scan.

it would just stay in dim grey and say "turning wifi on" and freeze there.

I've used CM10 and GB stock and fully formatted and wiped my phone when I installed both of them.

Some people told me it could be the WiFi chip that is broken but I can't get a new one in my country and my warranty was for a year and I've been with this phone for over a year.

ANY HELP IS WELCOMED! THANKS XDA COMUNITY :'/

Edit: Seems like I'm not the only one having this problem, but I'm the first one to post here in XDA.

So, do you guys consider this is a hardware problem? why is it happening RIGHT NOW? My guess is, this is happening to most of the 1 year old Galaxy S2 devices.

I uploaded the logcat again, this one might contain more information than the old one

SEEMS LIKE IT IS A SOFTWARE PROBLEM When I first got this problem I was in ParanoidAndroid 1.6(CM9) WiFi wouldn't turn on at all, then I wiped everything and tried again, and nothing, then I flashed stock GB and it would turn on for 5-10 seconds and turn off again by itself and wouldn't scan or find a network at all, now I wiped my phone again and flashed CM9 resurrection odin file and wifi turns on now and it ACTUALLY FINDS THE NETWORKS NOW! I just cant connect to them and WiFi keeps turning off and back on by itself, on GB it just turned off and couldn't find networks, I think I'm getting closer of a fix! I'll post a logcat of CM9 resurrection with my wifi problem soon.

The second logcat provides info of the WiFi problem, I actually got to connect to my WiFi network, I turned it off and tried to connect again and nothing :x I flashed fluxi kernel to see if it would change something it got worse, with the custom kernel It wouldn't even connect or scan, it just gets stuck at "Turning WiFi On" like in the beginning. Any ideas?

Here's a list of the things I have tried

*Fully formatted my phone (SD cards and everything in CWM mounts and storage)

*Tried fixing permissions

*Tried formatting again and flashing a stock GB ROM Odin

*Tried formatting everything again and flashing CM9 Resurrection odin

*Tried factory reset and flashing CM10

*Tried flashing the PIT file

*Tried replacing my current EFS folder with another folder I had from a few months ago by replacing I mean I just copied and pasted with root explorer

*Tried flashing Fluxi kernel on CM9 Resurrection

At the beginning of this thread my WiFi wouldn't turn on at all, Now it turns on and scans networks (currently using CM10) if it was a hardware problem then software changes wouldn't affect my problem since it's hardware but software changes are improving my WiFi so I THINK this is a software problem. It is weird how a lot of people is getting this since the last month.
