Hello,
I apologize if there is a post about this but I did not see one when looking.
So as of the OTA update to 4.4.2, I am no longer able to turn on my wifi at all. When I try to toggle it, I receive a notification from Knox that it has blocked it. I had tried to root my phone prior and Supersu was unable to install because it couldn't get past knox before. (this was prior to the OTA update to 4.4.2). Now that I am updated, my phone barely functions without freezing, and I can't turn on the wifi. I'm not very experienced with rooting Android phones so please forgive me, but how can I restore my phone to an older firmware or how can I root/fix it in its current state. I have tried Saferoot with no luck and Supersu is still unable to disable Knox. Any assistance / advice is greatly appreciated!

Your update failed to completely go through. Versions and builds should end in the same suffix (NAE), You can try to manually install NAE a second time to see if the update completes. If that fails, I know there is a thread to help with that issue further.

in order to fix you have to flash the old update via odin but you need to check and make sure you have the mk2 bootloader and you can check by downloading phone info from the play store
This is where I downloaded the MK2 file
http://forum.xda-developers.com/show....php?t=2601443
This is the directions I followed to do it, I used the MK2 file inplace of the MDC (4.2.2) file though. http://qbking77.com/development/how-...ung-galaxy-s4/
After you do that it may freeze at the sprint logo which then you need to put it into recovery mode and clear cache and factory reset.
after that you can try the upgrade again by going into settings, more, application manager, all, google services framework, clear data and force stop, then go check for update in system update and it should redownload the update and lat you install it again.
Hoped this helped

Hi guys! I hope someone could help me. I just bought a Galaxy Note 3 (international version) yesterday. The phone's fine. It's just that I am unable to update. I am able to download it but when my phone reboots it shows a dead android with a red triangle on its chest. I read flashing the firmware via odin can fix it but problem is our internet is hella slow. I couldn't even complete downloading my brother's Note 2 firmware. Any way I can make it install the firmware successfully? By the way it's OTA. I am able to download the update, just won't let me finish installing it. Goes around 35% then the android on the black screen dies with a red triangle on its chest.
EDIT:
I have official firmware, never rooted, just got it yesterday. Still factory new.
version 4.3, build # JSS15J.N9005ZHUBMI7, baseband version N9005XXUBMI5, Kernel version 3.4.0-1626679

Was your phone brand new? And did you check your KNOX status? -- reason I ask, after you've rooted a phone you are unable to recieve OTA updates, unless you use Wanam to fake system status, then you can download the OTA update but it stalls on the install about 35% or so in..
Best advice, is grab the stock image from sammobile (ballache to download I know) then use ODIN to flash her back to original state.

i didn't root the phone when i got it. it's fresh and on official firmware. have no idea about KNOX, that's new to me. if it helps, my device status says "official"
unfortunately the internet in my area is very slow, i couldn't download firmwares from sammobile. i tried several times

Ah Ok, if it says Official it should be good to go. Seems like maybe the download has gotten corrupt due to an intermittent internet connection.

OK, then maybe you should learn a few things before trying to update - Knox is a security system in latest Samsung phones that is supposed to be triggered/set when you root (or install any custom kernel/recovery). Your initial (old) firmware could still let you root without triggering the Knox flag, and then you can update to the latest firmware for your region using Mobile Odin Pro and still keep your root AND without triggering the Knox flag. However once you update using Samsung OTA / Odin / Kies to a firmware more recent than MJ3 you can no longer root without also triggering your Knox warrany flag - read more about this in the Universal Root De La Vega thread!
i gave up after several tries, since i'm on 4.3 i think that would do for now. maybe it's just downloading a stability update or something? everytime i do an OTA update, it tells me that the download of the new firmware is complete then reboot. when i get to 32% the droid falls flat on its back and shows the red triangle on its chest, over and over. i don't lose my phone data or anything. just won't update. i'll wait for 4.4 Kitkat instead. hope i'll be able to update to that when it comes out.
EDIT: i tried going into recovery mode, wiping cache, and factory reset.. still no dice. maybe Odin's the only way i guess. problem is my internet connection lol

i managed to update mine using Samsung Kies3 (not Kies, but Kies3). Hope updating OTA is fixed in the future with the update i just did
Hello everyone, i'm a new member. I apologize if my english is not good enough.
After been driven insane by one pre-installed app from my Operator (Claro Peru) i decided that it was time to root my device to get rid from that pest. I'm a noob, so i started to investigate about the safest methods to not damage my phone. My Device's model is SGH I337m.
The plan was to update the FW from JB 4.3 that came with my phone to 4.4.2 and then proceed to root. I downloaded the Canadian 4.4.2 FW with build version I337MVLUFNC1 and installed manually with Odin. After the phone rebooted, my S4 was upgraded with 4.4.2 but Samsumg keyboard was going insane, so i went to the apps and solved that cleaning the cache/data. Then i noticed that the Wifi wasn't connected, i tried to turn it on, but then a message with a shield appeared saying that my device security stopped the operation. Beliving it was only a problem with KNOX, i installed autoroot (CF-Auto-Root-jfltecan-jfltevl-sghi337m) with Odin, open SuperSU and stopped it from working, but the Wifi still wouldn't connect.
So the first thing that crossed my mind was to unroot and do a factory reset, didn't work. The FW still was 4.4.2, so i´ve been searching solutions with this FW because i've read some cases of devices that stopped working completely after trying to do a downgrade. so i don't want to go to that route for now.
After a couple hours of search, some solutions i found on the forum were:
- Install Faux123 Kernel (Found on Youtube, this would be the thread i think http://forum.xda-developers.com/showthread.php?t=2273437http://forum.xda-developers.com/showthread.php?t=2273437
- Flash a modem for i337m
- Safestrap recovery and bypasslkm.zip
- Downgrade
I haven't tried any of this methods because i dont want to get into a deeper trouble. In the first solution i'm not sure what to do because this is the files the author recommends for canadian models (i337m), but when i enter here http://faux.romhost.me/jflteatt/jb42/http://faux.romhost.me/jflteatt/jb42/ only jflteatt appears, and that would be i337 model, isn't it? I thought that installing it may cause more troubles, so i didn't do it.
For the flashing modem method, i'm not really sure if installing a modem from another country would get me in trouble, so again i didn't proceed.
I found the Safestrap and recovery method on a downgrade thread for the i337, so again, didn't do it.
So, is there a way to get one of this methods working on i337m to get wifi working again, or is there any other better method to get back wifi.
I would really appreciate any help you can give me guys.

ok so you have the i337m canadian version... making anything related to safestrap and the att i337 irrelevant, completely different methods so don't get them confused lol
you were updating from stock 4.3 right? your best bet is to factiry reset and reflash stock fw for 4.4.2 before you brick your device... kitkat is very different from 4.3, maybe read up on it a bit too...
for ex, the "message with a shield appeared saying that my device security stopped the operation" isn't related to needing to root, it's an option under security settings.
to enable superuser on kitkat you need to enable developer options, then enable superuser. I prefer supersu so manually install that from play store afterwards. I recommend checking and/or enabling this as soon as the phone completes booting up after flashing.
also I think there's a known issue w/ 4.4.2 and wifi not turning on until after 2nd boot completed if I rememebr correctly, been using 4.4.4 for awhile now though so could be wrong...
good luck and check out the help section :angel:
I rooted to 4.4.2 and it went fine- then I realized I had lost wi-fi.
I have tried to restore and tried using odin and zip files to install a stock rom after I found a similar problem with link on
Sprint forums saying it will fix the ""button won't stay on" but the fix only works if the device is in stock rom.
answer on Sprint forum says baseband version was mk2 needs to be nae.
Return the phone to stock, run the fix for the wi-fi and then re-root.
I have downloaded and ran several roms that say they are stock- I've factory reset, cleared cache, no matter what I do,
I end up with a rooted device in 4.4.2 and no wi-fi. If I could just get the wi-fi back I would take it at this point
This was just a little quick upgrade that turned bad and long
The Sprint forum had a link to get it to nae, but wont work if rooted., so need to put the phone back to stock- run the patch and then can upgrade to kit kat again
TLDR: I cannot get my Sprint s4 back to any version that isn't rooted. I have tried several (lots) of roms that say" stock-unrooted" rom,
Never goes back to stock- stays rooted without wifi-
Ran a rom VPUAMDC_L720SPTAMDC_SPR but when I install I get msge "ifooter is wring signature invalid" - and it fails.
reformatted the sd card, tried different roms and get some message and it stays rooted and no wifi.
TLDR: need to get stock rom so I can get back wi-fi and then root the whole thing. as 4.4.2 Or 4 , if it exists)
Any options and any ideas as to where or what to do?
EDIT: for clarity cause I am not making much sense at this point
Thanks
Heh... a TL;DR for a TL;DR... the internet is becoming one crazy place.

Maybe a dumb question, but why not just unroot first, then?
Anyways as my title says, i don't have wifi. I had first rooted my phone, but then I unrooted my phone by flashing some unrooted os on the samsung which caused two problems. My wifi and mobile data didn't work at all, but after I took it to a repair shop they fixed the mobile data and got it working again and rooted my phone but not the wifi part. According to the person that tried to fix my phone, the current android os, 4.3 - jellybean, that i flashed via odin is preventing the wifi from working. I don't really know whats wrong with the phone but can anyone help me? Also by baseband version is 1337UCUFNJ4 and the build number is JSS15.1337UCUEMK2. Should i try to find a ROM that matches my baseband version and flash it via odin? Thank you in advance!
P.S. This is my first thread, so please tell me if i violated any rules.

im having the same problem and i think we both have knox stupid security back on the phone that's blocking the wlan to start from bad permission or encryption
so personally yeah i will install back the original firmware (before 4.3) from factory reset (or via odin if i have to force it) then im gonna re-root the phone
having back permission ill remove knox (probly with titanium) lock and box bs from base firmware and probly remove root right
then im guessing ill have my internet back now will i go full rom again or basic function thats a good question
so many freaking remote exploit lately
ill let you know if that fix it
I also just found this
om22 said:
1. untick "Auto reboot" in odin
2. flash the stock rom again
3. reboot your phone to download mode again (by holding the power and vol down button for 10 sec)
4. flash the stock rom a second time with auto reboot ticked
This will fix your problem.

seems that clicking auto reboot might be the cause
so would i install the I337_NJ4_Stock_Kernel.tar.md5 file following that method or would i have to find another firmware/rom/(i don't know what to call this) unrooted

so if you dont mind the 9505 change (more rom and solution for 9505) id go with echoes for all in 1 fresh install solution and its a nice rom
Instruction can be found on this thread : http://forum.xda-developers.com/showthread.php?t=2372286
knowing the problem was modem i did also found this solution to re-flash and fix wifi on i337 without changing to 9505
Follow these instruction to stay i337 : http://forum.xda-developers.com/showpost.php?p=46762296&postcount=1
but i have not tested for i337
in the end i got this setup

Hey Guys, I'm brand new to these forums, and to this whole community so bare with me.
Basically I bought my T-Mobile Samsung Galaxy S5 phone around the time it came out, and I also had installed root on it via towelroot when Towel Root was first released. I did not update the phone at all for a long period of time and everything was working fine, until one day I was browsing under settings and accidentally tapped the "Software Update" button, then T-mobile auto-pushed an update onto my phone.
This update has caused the root on my phone to not work at all (Deemed useless) So I clicked SU and only a black screen popped up when I tried to open the app, so I uninstalled it, reinstalled it then got a message saying "There is no SU binary installed, and SuperSU Cannot install it. If you just upgraded to Android 4.3 you need to manually re-root your device" So I tried to re-root via towelroot method again. It seems the T-mobile update made my phone "Unsupported/Uncompatible" with TowelRoot's obsolete techniques, so now I'm in dire need of help.
My phone tried to push another t-mobile update (This time to upgrade to Lollipop) but it failed after attempting to install it after a reboot. So not only will my phone not update to Lollipop, but I'm not even rooted anymore and am unsure on how to get back rooted, or what to do next since I used rooting as a primary source to store apps on my SD Card. Kind of like i'm stuck in one spot? (Can't update your phone/can't root it the old method)
I'm brand new guys, Please can you break down to me what I should do, in order to obtain root again, and possibly be able to upgrade to Lollipop As well as prevent further pushed T-mobile updates? Here's some info if you need it
S5 Model Number: SM-G900T
Android Version:4.4.2
Kernel Version:3.4.0-262.. etc. (Tell me if you need the full kernel details)
Any help would be greatly appreciated! Thank YOU!
Flash this with ODIN

(Will trip KNOX and void warranty)
Or flash a pre-June 2014 KK Kernel, root with Towelroot again, then flash back your current Kernel
Is this the only solution? And also is it the right one? o.o
Can anyone else please give me some feedback on the situation? I want to make sure I do this right, please just a little helps.
