'K bro let me figure out what's the situation. Tell me how & when exactly did this happen. After you flashed a new rom or some update or something. Also which rom and all you've flashed in the past before and after wifi issues started????
Sent from my SM-G800H using Tapatalk

Actually I can't tell cause I got it used, it was with stock official 4.4.2
It worked sometimes, most of time not, or just gave a fake WiFi Signal..like it says it's connected, but actually no Internet.
So I Flashed another stock official rom via Odin, got same results, then I tried flashing some fixes I found around the Internet, the ones you put in PDA and flash, it worked for sometime then stopped..
Rooted and tried deleting efs, no luck.
Lastly I Flashed 4 Files factory ROM 4.4.2 with its pit file.. It didn't work.
Of course I've tried it on other routers..
So no matter what I do it stays on "Saved, Secure"
It's really weird thing as Bluetooth and Hotspot are both working..

Don't get me wrong but in your first post you said "different stock ROMs" later you said "another official stock ROM", dude as far as I know there's only one stock ROM for every device, it may have different Android versions like 4.3 or 4.4

Okay so let me tell you what happened with me was something similar issue.
I flashed the GeNxt N4 rom and after that it is instructed to flash Deds kernel but cwm is buggy and it behaves weirdly so you cannot return to recovery to flash kernel and rom withing the same boot into recovery without reboot.
So i changed roms but to my surprise i had wifi issues in all of 'em. So i used philz recovery and flashed N4 rom with the Deds kernel and finally fixed.
So maybe yours the same case. The previous owner did something similar and wifi issue could'nt fix so he gave to you.

Thanks friend, I'll try it.
But is it mandatory to do it over (4.4.4 base rom ie gennxt n4) or directly on stock 4.4.2 would be fine?
Thanks in advance.

Do on Gennxt. Cuz what i think is the problem is previously this rom was maybe flashed on your device without Deds kernel as you say someone else used it before and the bug is showing up on every rom since it was not fixed.
Again i am just trying to guess what the problem is. Hope it helps

please help! I made a dangerous mistake. I have a problem...

hi
I made a mistake when a I wanted root S3 with CF-Root kernel, and I flashed kernel of Note2
then display became Blue. and now it's touch doesn't work.
I flashed CF root of s3 and doesn't fixed.
even I tried Flashing original Rom
but it does not worked
and I lost my touchscreen
how can I fix that
I think kernel of note2 does not allow other kernels to flash correctly
(sorry ! I can't speak english good)

Sent from my GT-N7100 using Tapatalk
I m not sure about this...
Maybe you can try installing new kernel via adb...
Not sure if it will work though...
If the recovery is working than wipe everything there, system, data, preload, dalvik etc.. Then go into download mode and flash a official Samsung rom, some not branded 4.1.2, btu i think is the best, after that go into recovery again wipe data and cache, and than try to reboot. If that doesn't work try flashing only kernel via adb.

Every official ROM will work,just choose your model and ROM version you want.

If you can get it in DOWNLOAD mode. You should be able to flash a stock rom with ODIN. Then re-root, flash Custom ROM, etc.,etc.
That's the only way I have repaired other peoples botched updates and stuff. :good:
The Note 2 screen needs more power than SG3 screen, so the kernel you mistakenly flashed could have damaged the hardware itself.
Do as fbarcenas says. If it doesn't work, I think you're gonna have to replace the screen unit. Try everything else first, of course, and good luck !

How? You should flash via odin, not custom recovery. Can you get your phone into download mode? If yes flash stock official Samsung 4.1.2 rom.

Have a look at this thread : http://forum.xda-developers.com/showthread.php?t=2231393
I remember that something similar to what you did happened because of a mistake from the developer and Codeworx and others tried to help and solve the issue, but I didn't follow that story until the end, so cannot tell you if they succeeded.
Try to use some Rescue Roms the ones with the pit files. Tough problem mate sorry?

ive seen a similar issue...and im enclined to agree with regaber
u may want to consider getting a new screen...
If you have flashed a stock rom, that will have replaced all files, including the kernel, therefore if it's still not working something has caused hardware damage (the only option after flashing stock and wiping everything.
If you flash a touch recovery is your touchscreen working in that?

Auto Rotate problem

I was with Kitkat German, and suddenly - when I tried to rotate the screen, he also turns around, but he did not turn around right .. and the camera takes pictures upside down, even when I went back to -4.2.2 same thing and not solved ..
Access Warranty?
UP
It's the kitkat modem that messes up the auto-rotate and some other things, have you tried downgrading the modem if possible? Download a flashable zip for the previous modem and flash it via recovery.
Link please for old modem?
thanks.
I'm currently having the same problem. The old modems are not working.
Sent from my VS980 4G using Tapatalk
I installed the old modem and now the screen does not turn around at all.
You need a Kitkat baseband for a Kitkat ROM!
Some folks reported that recalibrating the gyro helps.

any other ideas?
Are you using an Nordic/Scandinavian variant? - if so, flash back to stock. There is some issues with them particular variants and has been since 4.4.2. - Even if you aren't I'd go back to 100% stock to be 100% sure first to determine if it may be a hardware issue also.
