Default [Q] Weird problem. Software or hardware?

Hello everybody,

First of all, on 4.3 I couldn't get wifi to turn on. Here is a list of what I tried when I was on 4.3:

- I've already flashed many different stock and custom roms
- I've tried the wifi fixes, the non-hlos.bin fixes with every rom
- Friedrich420's build.prop tweaks and wifi files.
- Custom kernels
- Different modems
- Dial *#0011# and disable wifi power saving mode.

Now I've updated to 4.4.2 XXUFNA5 to see if that fixes the issue, but still no luck. Now it's even worse. No wifi and I can't even root the phone anymore (using cf auto root, haven't found another way yet but SuperSU sais 'no su binary installed' and closes...). However I can still install a custom recovery, but after installing any rom (4.4.2 ofcourse) the boot animation doesn't change, still says samsung, and I'm in a bootloop . Can't even install a pre-rooted stock rom. Tried both cwm and twrp several times.

I purchased the phone with the wifi problem, in the hope i could fix it and have a cheap galaxy s4. The previous owner said he hadn't done anything to the phone (no software of hardware changes). However konx was already 0x1.

Does anyone know what the problem can be?

Thanks for your response, but as I said in the first post I've already done that many times...

The same happened with me.
I flashed the stock rom and the problem got solved.
I guess problem was with the kernels

The only thing you possibly can do now us to head to a service center.

Yes I've also tried a few custom roms on 4.3, but on 4.4 I ways get in a bootloop when trying to install a custom rom (4.4 ofcourse). Bootanimations doesn't even change. I don't think the error is in the system or the data folder, I've tried really everything within these folders. Can the problem be somewhere else? There's also a wpa_supplicant in etc/wifi, but that gets updated bij the wpa_supplicant.conf in data/misc/wifi right? So I don't think that can be the problem?

I am in the exact same boat as you except I didn't upgraded my bootloader to 4.4.2, was about to these days. I flashed about 7-8 different stock firmwares with the wifi fix for each. I, same as you bought the phone cheaper with this problem and thought I could fix it. I read somewhere that downgrading to 4.2.2 will help somehow but downgrading for me is impossible. I am getting desperate, please if you ever find a fix post it here or private message me. I know that is software and not hardware because in the first day I bought it I managed to fix it on the firmware it came with MK8 by flashing a lot of stuff in random order : CF auto root, wifi fix MK8, MK8 modem, philz_touch_6.07.9-jfltexx, don't remember what I did exactly, but made it work and then installed another stock firmware XXUENA4 , and it kept working on this firmware also all day long, and then next day after I started the phone it worked for about 5 min then it turned off and stayed off till now no matter what. I tend to be a rational person and try to find reasons for everything but for the life of me I can't figure out this one so really please help me, any one with any possible explanation. Can it be hardware after all? But how did I fix it once, and why can't I fix it again by doing the same same steps? My new plan is to try flashing bootloaders only as if this might work somehow. At this point for me is all about trying all sorts of mojo like flashing exactly 3 times modem then 3 times wifi fix, wipe data and factory reset from stock recovery before rom boots first time, and all sorts of wackadoo stuff.
Please really help me because my only other solution is to change the motherboard for 200 . Btw mine is i9505, u didn't mention yours.
