I9505 stock I9505XXUGNF1 knox 0x0 no wifi - Galaxy S 4 Q&A, Help & Troubleshooting

Hi all!
I've been searching for the solution to my problem but it seams that it is unique. Anyone who had similar issue was on unofficial rom, didn't flash correctly, was rooted or knox warranty void.
Anyway, my I9505 ITV, after official kies update from 4.2.2 to 4.3 lost wifi. Icon goes to gray/green and back to only gray - disabled.
As kies didn't want to update it to 4.4.2 (I thought upgrade would fix the wifi issue), I downloaded and flashed the newest official 4.4.2 (at the time - I9505XXUFNB8) for it with odin. All went smooth and I got kitkat on my s4 but still no wifi. Today kies informed me about the newest 4.4.2 (I9505XXUGNF1), I flashed it, done factory reset/clear cache again but still nothing.
*#1234# gives me
AP: I9505XXUGNF1
CP: I9505XXUGNF1
CSC: I9505ITVGNF1
meaning (at least I think so), everything (and LTE) flashed correctly, right? Everything else on the phone works, just wifi can't be enabled.
I would gladly trip knox if it would fix my wifi 100%, but would like to avoid tripping it just to try 100 potential solutions because there is a small chance that I can repair the phone under warranty.
So, I have 3 questions:
1) is it possible to fix my wifi without tripping knox?
2) is it possible to fix wifi with tripping knox?
3) or is it hardware failure?
Thank you on your ideas and possible solution!

[Q] On BMJ3 can i flash back to BMI7 without triggering knox

So i received 2 updates a week ago ( i kept cancelling them) to Bmj1 and Bmj3, but bmj 3 seems to be eating my battery with high AndroidOS usage. Can i flash to BMI7 without triggering Knox. Or to something else like BTU Dmj6. I have currently OXX Csc (it appears as ROM in Kies). I dont want to trigger knox.

Anyone?
AFAIK you cant downgrade due to the updated bootloader in MJ3 but you should be able to upgrade to MJ6 without triggering the knox binary counter
Is it safe even if it is different CSC?

[Q] De-brand i9505 4.2.2 using official 4.3 without tripping Knox?

I've a i9505, unfortunately it's branded (but no locked) in T-Mobile. I'd love to install 4.3 on it, but T-Mobile hasn't released it, so it's unavailable in Kies.
I would like to know if it's possible to use official (non-branded) firmware and _not_ to trip Knox (as it voids warranty in Poland). I've went through most of Knox-related threads, but I fail to see clear indication of 1) if it's possible 2) how to do that.
Also, does anyone knows if, after de-branding the phone, I'll be able to upgrade from 4.3 to 4.4 (for example) without tripping Knox?
Any comments will be appreciated.
Bump, anyone?

1. If u still having Knox 0x0 and android 4.2.2 only u have to root ur phone and delete the apps branded.
2. If u dont have updates in Kies is better. Don't void ur warranty and enjoy with ur 4.2.2 firmware.
OK, my point is to get Android 4.3 and not trip Knox - T-Mobile hasn't released 4.3 yet, and god knows when they do that.
Alternative question: is there a way to install official 4.3 without installing Knox bootloader?
i'v been looking around for the same thing, but i dont think thats possible without installing a custom made ROM
OK, let's try to put it another way: given that I have 4.2.2, do I risk losing warranty when I install CWM and some de-KNOXed 4.3 using Odin? Or Triangle Away will just work, and I'll be able to flash default software in case I need to service the phone?

Unbrand Galaxy S5 without tripping Knox

Hello everyone! I've bought a Galaxy S5 some days ago(SM-G900F) but it came with this firmware: KOT49H.G900FFXXU1ANE2,and it is branded by TIM Carrier. Now my question is,I want to un-brand it and install stock OS so I have updates earlier,but I am scared that I could trip KNOX Counter and lose warranty. Anyone has a procedure to do this? Also,will I lose warranty? Thanks in advance,and sorry if this may not be the right section.

There is always a risk when playing around with the firmware no matter the phone make, model and carrier/network. For what it's worth, I got a second hand branded S5 (SM-G900F) and flashed the unbranded UK (BTU) firmware on it after unlocking it using Odin. Knox still intact on mine as far as I can tell, reading "0x0". You might need to reset it a few times and maybe clear DALVIK/ART cache a few times to get the right CSC to appear on the phone and get OTA updates. But again in my experience everything is still working after debranding.

Just download the latest stock firmware United Kingdom / Europe (BTU) from Sammobile,, download Odin then use Odin to flash the BTU firmware, Factory Reset the phone after flashing to set the correct CSC and clear the Caches, flashing a stock rom won't trip KNOX. Flashing Custom roms,Custom Recovery, kernels etc will, staying stock wont.

Hi there
My galaxy s5 got into water yesterday so I checked the back of the phone and saw the litmus paper became red, then I thought that now I can finally root my phone without concerning lol ), then I flashed Modem: XXU1ANI1 and intend to flash rom later. But then I told my friend who works at Samsung Services and he checked my phone and said that it has no problem so it is still under warranty. So I want to ask you guys that whether I flashed the modem XXU1ANI1 affect my warranty or later if I can update stock firmware via OTA. Can I flash back to the latest stock modem XXU1ANG3 for G900H Vietnam without tripping knox? or if it has any problem?
Please help me , I really appreciate any help you guys can provide.

Yes, you can flash back to your stock modem without tripping Knox (if it has not been tripped).
To check whether your Knox was tripped or not, you can use Phone INFO ★Samsung★ app and look for the Knox Warranty Void status (under GENERAL INFO section).
Thank you so much

Downgrading to 4.2.2

Hey guys i have a galaxy s4 19500 running android 4.4.2 kitkat ( argentian (aro) firmware )
My phone was recently on 5.0.1 lollipop (indian ) version and i downgraded to 4.4.2 argentian firmware following a thread here on xda
I was wondering if a downgraded to 4.2.2 JELLYBEAN was possible ?
I mean i know it's super messy becuase of knox but if we take all the precautions like backing up efs partition then can the downgrade be done ?
I really think that jellybean is the perfect firmware for s4 and kitkat and lollipop have both made my s4 experience only worse
It would be awesome if i could go back to 4.2.2 jellybean and enjoy my old device
If you downgrade to 4.2.2 you will brick the device. Since new bootloader( version of Android 4.4.2 i think), you are not able to install 4.2.2 without brick.
@sgalchev: Not true at all. It is possible to replace 4.4.2 with 4.2.2 as I have done it in order to resolve issues I had with my S4. What ends up happening after doing the downgrade is that upon every boot and upon every trip into the recovery you will get a notification that the kernel or recovery is not SEAndroid enforcing. Other than that everything works normally.
Now, downgrading from 5.0.1 to 4.2.2 may be a completely different matter, but I suspect it too is possible.
Yea, shure, but you can't do it without ticking the Knox flag[emoji6] Goodbye warranty...

Hey man it feels awesome to know that it is possible to do can you please give detailed explanation of how you did it
I would really like to do it no matter how much hard or risky it is and i have already downgraded from 5.0.1 to 4.4.2 now i just need to downgrade to stock out of the box jellybean software
@sgalchev: Changing the goalposts? You flat out stated the OP would brick his S4 if he attempted to downgrade. When called on it, you switched your argument to tripping the Knox flag. As he mentioned in his latest post, he had downgraded to Android 4.4.2 from Android 5.0.1, so it's likely his Knox flag is already tripped. Even if it wasn't, I can't comfirm whether the Knox flag will get tripped as my Knox flag was tripped when I bought my I9505. Tripping the Knox flag != bricking the S4.
@tdssmarty16: Keep in mind that while everything worked, it took two flashes of the ROM to do it, and I only kept it on 4.2.2 long enough to verify that the hardware and firmware issues I was having were resolved. I then went back to 4.4.2. In downgrading to 4.2.2 I went to sammobile.com and downloaded the 4.2.2 firmware from them. Other than that, I simply treated it as if I was doing an upgrade through Odin. Unlike going from Android 5.0.1 to Android 4.4.2, going from 4.4.2 to 4.2.2 should be a piece of cake.

Which model S4 do you have? Only certain models can be downgraded to 4.2.2.

I downgraded my i9505 from 4.4.2 to 4.2.2 but had no sound so I went back to kitkat.It is possible to downgrade but I don't know is it possible to be fully functional.
I did it long enough to both check my SIM tray at the time, and to unlock the device. I wasn't getting any signal (expected), but I didn't check sound. I do suspect that if the 4.2.2 modem is flashed a second time everything would work. The only indicator that you were ever on anything higher would be the warning the bootloader pops up on every reboot about SELinux.
No sound,no wifi
I forgot first time to say wifi also didn't worked.I don't care for my warranty because flag was already tripped and now my device is older than 2 years so I can try some solution If someone has one.
anyone active here? it's not possible to downgrade to jelly bean anymore as the bootloader is locked to downgrade max at 4.4 as 4.2 will not work at all
if anyone has a ideea on how to do it (some people did it) i would be verry happy if you could share that info
I have not seen a post where someone running a 4.4.2 or 5.01 bootloader had successfully downgraded the bootloader to 4.2.2
