Wifi won't turn on on stock or custom roms. - Galaxy S II Q&A, Help & Troubleshooting

Hi, we've got the old S2 out a drawer to lend to someone, it's not been used for 6+ months but worked fine then, the wifi no longer works, it thinks about turning on for about 10 seconds then switches back to off. I've tried a factory reset, I've tried CM12.1, tried going back to a different stock rom, still nothing at all, all does the same. Done lots of googling and people say to enter *#*#526#*#* to see what the wifi test says but that code doesn't work for me on 4.1.2, just get a sorry this number is not available.
Any ideas, be good to get it working.
Thanks.

Mine did this too, try taking the SIM card out. In the end I've completely wiped it and am now running CM12 nightly and it's being used by one of my lads as a gaming thing, and it works well for that (on WiFi) now I've sorted the partition sizes.

Pretty much self explanatory
Camera was working yesterday
Today its not :'(
I had this a few days back - turns out i'd been using the phone in 'torch' mode, and it had turned itself off after a while, but obviously didn't release the led function back to the camera.
When I cycled the torch back on and off again it was fine. I imagine rebooting would do the same thing?
Hope that helps a little!
yes, just reboot the phone and it will work again, had the same thing
have tried multiple reboots and even taken the battery out! not too sure what im supposed to do....may just reflash the original rom again to see if it makes a difference

just a question, but had you changed the lcd density before the camera failed? if so, did you adjust it below 182?
nope, lowest i set it to was 210, but that screenshot was taken at the norm 240
ok its happened again!!! i flashed the latest update and rebooted and it was fine, camera app loaded up fine...once i installed a theme it was saying the same message!!!! is this a hardware fault? i can hear the camera clicking every time it switches on
Just flashed the original firmware back onto it, the o2 one and its saying the same thing.....is this a hardware fault?
***************EDIT******************************
So i did a factory reset and the camera really is working now
anybody have a clue why this is happening? its slightly annoying....going to debrand and root to see if i can locate the problem...

T-Mobile UK MB860 Intermittent problems with data and wifi

Right, ive noticed a few prople have had similar problems but nothing that is the same as what im am experiencing.
basically, about 6 weeks ago i flashed the Alien v4 rom (wanted to retain webtop else i would have chosen cm7). this has worked flawlessy till now. Ive suddenly started having issues with wifi and data connectivity.
When connected to wifi i get internet access for aropund 2>10 minutes. then i lose it, although my phone still says im connected to the network. When i turn off the wifi, i check the wireless setting and it says that mobile networks are not connnected. when this happens, the data icon in the task bar is grey not green, ive noticed i only get a connection when its green.
System version:
4.5.91.MB860.ATT.en.US
Baseband:
N_01.100.00R
Webtop:
WT-1.2.2-110
Kernel:
[email protected]#3
I had the same problem before, a few months ago. Think it was just an issue with the ROM I was using. Have you tried a different ROM?
Not yet, will be when i get home. I was under the assumption however that alien was the best (webtop rom) in terms of speed and stability
Just backup your ROM in recovery - try out as many ROMs as you'd like to try. You might find one that both resolves your problem and suits you better, and as long as you have that backup you can just jump straight back in where you left off with your current ROM.
I have a backup anyway. Always make one once I know a rpm works after flashing. Been flashing for too long with many a handset to not keep backups. Ive learned the hardway with this haha

Did you factory reset it? Or it just booted like that. Looks like its in some sort of Clock Work Recovery or soft bricked which is not a big deal. Someone here will help you out soon as i am not a Pro on recovery. Same thing happened to me when i bought a Galaxy S2 a few months back. Just hang tight until some one gives you directions or search the forums.
Try and "Reboot" it while highlighted by hitting the power button. Thats at least how i reboot out of clock work mod for the Att version. Next step prob would be to highlight wipe data/factory reset. But again wait until someone confirms this for ya. Shouldn't be long
Just curious, what did you trade for
all good got it figured out. thanks

Wipe and flash a stock rom to test, the status bar appears fine so probably not hardware.

It does happen on the status bar, just seen the problem happen a few minutes ago, it's quite erratic. I'll try flashing back to stock and update. can't take a photo of it at the moment as I don't have another camera I can use (used a friends this morning)

Go to Settings > Motion turn it on and tick Palm Swipe to capture then when you want to take a screen clip swipe the screen with the palm of your hand, then upload that image no need for a camera
Still doesn't look like a hardware issue.
sent from the state where marijuana is NOT illegal !
putting stock back on it seems to have fixed the issue.
Shame that I really don't like the stock s3 rom at all

No one said that you had to keep stock. Flashing stock is a simple Hardware v Software test.

I realised that after I said it
So its still happening on stock ( all be it after a few days ). Any suggestions of what I should try next?

Camera - Black screen or fuzzy white lines?

I have a problem. Camera wont work. Most of the time its a black screen and other times it kinda works but i get the image below, and it takes pics like that but you cant view them. I removed apps that I have installed since I noticed this and nothing. Any ideas on this? I looked everywhere for about 2 weeks now. Not sure what to do....?
If a factory reset from the settings menu is recommended... what exactly happens to the custom ROM and kernel? Do they need to be reinstalled or...?

Replacing the camera module doesnt work. Does the same thing. Any ideas? I doubt it since I have gotten ZERO replies. Was hoping at least ONE person on here has had this problem... guess not. Thanks anyway everyone!
I wonder if it's the kennel you're using. AJK 1.25s is pretty old, and while it is the Samsung version I can't remember if it's for the ICS version you're running; maybe AJ can pop in and reeducate me.
Anyway, a quick test would be to nandroid and flash the rom again without changing the kernel, then see if that solves your problem.
One other thing, don't factory reset from the settings menu, always do these things from the custom recovery.

I just flashed Shostock 3.0.2 the other day without flashing a kernel before I changed the camera module... same result. Thanks for the tip on factory reset.
