Repair malfunctioning Samsumg S4 - AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin

I have a AT&T Samsung S4 that I would like to give to my daughter. Unfortunately, the S4 is out of whack. First, I keep receiving the message "The device has detected an application attempting to perform actions that are not permitted. These actions have been blocked. It is recommended that you restart your device." Second, Wi-Fi will not turn on. When I try to activate Wi-Fi from the pull down screen, it blinks green and then goes back to gray. Third, I cannot delete any of Knox apps. There is no option that allows me to delete the Know apps, just the option to force stop. Considering that I don't have cellular service (because the purpose of the S4 is just to use on Wi-Fi and download apps for my daughter), I can't really download apps without Wi-Fi.
Is there any way I can get my S4 to function properly again, such as reinstalling software? I'm not tech savvy, so I apologize. A lot of the threads I've come across only address one of the issues. Your assistance is greatly appreciated.

The wi-fi chip could be defective. I also have an i337 sitting in my desk that has no wifi.
You cannot delete knox apps without root.
Did you try a factory reset?

Yes, I did a factory reset. Is there a way to root the device without WiFi access? Given that I can't access WiFi, I can't access the Play store to download the apps I need to root.

You can root the device. But you need to be in stable condition first, like working everything fine and no system message popping up.
Could you tell me your android version, baseband, bootloader etc.. so that I can tell you the directions you need to take.

Look at this thread to get back to stock: http://forum.xda-developers.com/showthread.php?t=2616221

Android Version = 4.3
Baseband = I337UCUFNC1
Build No. = JSS15J.I337UCUEMK2
Kernel Version = 3.40-1921628
Secure Boot Status = Samsung
I hope this is helpful and thank you for your time and assistance with this matter.

You could try smartswitch or Kies to perform a factory restore. If that doesn't work, this thread may help: http://forum.xda-developers.com/showthread.php?t=2616221

It appears that your are on Jellybean 4.3 OS with Kit-kat NC1 modem.
You have several choices.
Like audit13 said you try smartswitch or Kies to perform a factory restore .
If that is not solved your problem you can flash the firmware via odin.
If you are not familiar with using odin this guide explain about the odin.
In that guide you will find the sections about how to get back to MK2 stock and links for the necessary files.
Once you were back on the MK2 stock see whether your wifi is working. If you want to stay on MK2 and root the phone you can use saferoot to root the phone. Here is the link for root.
You could also upgrade your android OS to NC1 Kitkat too. Then you could use Towel root to root the phone.

Thanks for all your help. Unfortunately, I tried the Odin method and during the process i received the Failed message in Odin. I suppose I'm SOL.

Can you post the screen shot of the odin message?

Did you try flashing the latest stock firmware from sammobile.com located here: http://www.sammobile.com/firmwares/database/SGH-I337/ ?

Here's the screenshot of the failed message.

If you download roms from sammobile.com, only unzip the file once and flash in ap.
Since it is stopping at the aboot.mbn file, either the rom you are flashing has an outdated bootloader or the rom is not for your phone.

How would I flash it? Odin?

Yes, ROMs from sammobile are flashed using Odin. Unzip the file once to yield a tar.md5 file. Then, this file is flashed in ap.

Yes I tried the latest stock firmware today and same problem...received Odin message "failed." Given that I cant seem to get back to stock via Odin, I'll probably trash the phone. Thanks for everyone's patience and help.

Dont' give up yet. You could install safestrap to get close to stock.

okay, so i follow safe strap instructions and bypass the odin steps in that thread? thanks for your help.

and just one last note...i cant even get passed the laoding screen. it is stuck so not sure safe strap will work if i cant download the app and get it the phone

What loading screen is it stuck at?
Maybe take it to a cell repair shop to see how much it would cost to force flash the firmware via jtag cable.

[Q] Failed root with odin, cannot detect with Kies 3

I recently got a Galaxy Note 3 from Verizon. I wanted to root the device, it was really easy with my old original galaxy so I looked at a few guides which were all using "Root de la Vega" and finally tonight in an attempt to root my device I used the guide at:
phonearena.com/news/How-to-Root-the-Verizon-Samsung-Galaxy-Note-3_id48247
I put the phone into download mode and connected it to Odin with the included Samsung USB 3.0 cable. I selected the root de la vega firmware using the AP button and hit Start to begin flashing. Almost immediately after the write starts it fails and on the phone it says:
"Secure check failed: cache"
Click to expand...
Click to collapse
In the guide it mentions there may be problems using the USB 3.0 cable so I tried it with a USB 2.0 cable with the same results. I tried rebooting the phone to see if it had wiped it. Indeed, it had been wiped and is now going to the screen which says there was a problem updating the firmware and says to use the Software Recovery Assistant to restore the firmware.
I am not sure why this has happened. I feel like I followed the instructions to the letter. After looking at some different guides I am noticing that many have you put the phone into USB debugging mode which the guide I was following doesn't mention. Is this why it has failed. Is this strictly required?
I would like to get this device rooted, but now my number one priority is getting it back into a state where it will be more useful than the paperweight on my desk. I tried downloading Kies 3 which I read can restore the stock firmware on the phone. I was extremely annoyed when I realized that Kies 3 would not recognize my phone at all. It says that the device is not supported by Kies 3 and gives me a link to check support (which just brings me to the Kies download page which clearly states that my phone (Note 3) is supported. I even tried to download the original Kies software which will not even recognize the device enough to tell me it's not supported.
Can anyone point me to a way to restore my phone to factory settings? Can I download the stock firmware and flash it with Odin, will this work if I couldn't get the custom firmware to flash in Odin (possibly because of not setting USB debugging?).
EDIT: Note that, following the guide, I did not check which build number my phone is before running Odin, now I have no idea which it is and what stock firmware to download. Is there anyway to figure out which build my phone was on or which stock firmware I need to download?
EDIT: So it looks like my problem is similar to this problem posted on XDA. I followed the link in that thread to this guide to restore the stock firmware. However, it has three different downloads for different builds, I am not sure which I should download or if there is a way to figure it out. Will any of them work? Can I try them one at a time safely until one of them works. I don't want to mess things up any worse than I already have.. I downloaded the MI9 firmware from that page, but this is just a guess... Anyone have any idea?
Any help will be very much appreciated.

Click the link in my sig and d/l the MJE tar, flash it in ODIN (instructions also provided)
Then, you can follow the root, safestrap and cust rom links...
All links, step by steps, everything you need to get you up and running are in the link in my sig
Start fresh with the OEM MJE tar, then go from there... Hit me up in that thread for additional help!

Thank you very much! I wish I would have found your guide first. I flashed the MJE firmware, was able to successfully root using Kingo (after a few attempts). I also installed safestrap and the open source superuser app.
Now I just have to figure out what roms I want, looks like I can take advantage of the multiple rom slots and try a few before installing one into the stock rom slot.
Again, many thanks!
Odin to MJE Question
Hi, my phone is fully stock with MJE on it. To root my phone, would I need to install the MJE tar file and also use King or just the MJE file? So far, I have had no luck using Kingo to root my phone.
Thanks

Just Kingo should do it for you. I did this last week stock on mje. Make sure you have usb debugging enabled or it won't work. I also used Kingo 1.1.6 instead of 1.1.7 and I had no problem at all woth knox or anything. It worked like a charm.

I used 1.1.6 because I wasn't sure if their new version was going to automatically add a custom recovery and trip Knox. I was reading the comments on their facebook page (Kingoapp) and saw one that said it will trip knox but a few days later read that it was a option to install a custom recovery. Instead of taking a chance I downloaded the older one and used that. Also in the 1.1.7 comments there is a link to official Samsung drivers if you want to be sure to have the latest ones. There are links for all their versions on the fb page if anyone wants to try that route.
Rooting w/Kingo
Finally was able to get root! What I did was uninstall the Samsung drivers and re-install them. Thank goodness it's finished. I also just installed HyperDrive and Beans. It's kinda nice having a choice each time I turn the phone on.
Thanks for your help.

I337 AT&T S4 - Return to Stock (No WiFi)

I recently bit off more than I could chew with my S4 (I337). I had 4.4.2 KitKat on it and wanted to root it to add teathering. I decided thought there was no root for 4.4.2 so I thought I would try downgrading to 4.3 then root. This seemed best because I didn't like the way the SD card is handled in 4.4.2 and some of my apps (like ftp server) have stopped working.
When I got the phone back up from flashing with Odin it says it has version 4.3. My WiFi will not turn on. If I slide the switch to on it slides right back to off and the phone tells me that an operation was block (can't remember the full verbage. I have installed and attempted to install many things on my phone. I have used recovery mode / Odin3 and Kies (Kies doesn't allow much).
At this point I just would like to get my phone back to 4.4.2 with the WiFi working. Then I can restore my backup and be back to square one with a lesson learned.
I have an I337 that currently thinks it has version 4.3 on it. The baseband version is I337UCUFNC1 currently. The build number is JSS15J.I337UCUEMK2.
If anyone can help I would greatly appreciate it. I have read and tried many things over a two day period and finally decided to ask for help.
Had this issue before on my Bell Canada S4, but don't recall exact way to fix it.
Think the solution was to find an older (might be newer) stock. I think I used a different version like the Telus Canada version as well and it ended up working. Then you update through kies after.

Wifi does not work because of the modem/kernel mismatch, i.e. MDB modem and MK2 kernel. Not sure what your goal was when you began flashing your phone but since you fortunately did not flash teh MK2 bootloader you are still able to locate the MDB full odin tar and flash back to stock which will resolve your issue.

If you don't care about losing your MDB unlocked bootloader you can get to the latest kitkat firmware by flashing the NB1 full odin tar from here:
http://forum.xda-developers.com/showthread.php?t=2674223, then once flashing is complete go to settings/more/about phone/software update then take the ota update to NC1 which is the latest kitkat version for our phone.
But what I would do is keep your unlocked MDB bootloader and since you already flashed the MK2 AP file you can get your phone running well again by flashing the MK2 modem: https://mega.co.nz/#!pwESna5I!YK7EKG37xXIG1ReB-Z-mfSMoXNkXQ9t2EdMK9ofgJKg
From there, there are still a number of options available to get to kitkat which I won't get into.

Do you already fix it??? cause i have the same problem
Same question, different thread!
Not even an hour ago did I answer the same question in a different thread: How do I get WiFi working on my S4?
Well here you go.
My original answer: http://forum.xda-developers.com/gal...-4-4-2-nb1-t2850878/post54978150#post54978150
The problem is, in order to get WiFi working, you need to install the NB1 modules, but to do that, you need to install Safestrap. However, you can not install Safestrap because the app keeps closing on you. There is a simple fix to this, which I will explain later. For now, just read this WHOLE post BEFORE you do anything, and keep in mind that I am NOT held liable if you mess up your phone. Use this at your own risk.
1.) Root your phone
If you're already rooted with something like SuperSU or Superuser, skip this. If not, read ahead. Download and install the Towelroot APK file attached to this post, open it, and click 'make it ra1n'. If your phone didn't reboot, now you have root (they need to trademark that). Now, down below, I also included the APK for SuperSU. Download and install it. Now open it. When you open it, let it install the 'Normal' way, not via the 'TWRP/CWM' way. Also, when it asks you to disable KNOX, say yes, wait a couple of minutes (it will still be loading) and reboot your phone. Open up SuperSU again, click 'Yes' to disable KNOX again, and now you have a good base to start from.
2.) Install Safestrap AFTER fixing the error
The error your are getting is easily fixed. Go to the Play Store and install 'SELinux Mode Changer'. Open it, grant it root access, and change the mode to 'Permissive'. Now, open up Safestrap again (you mentioned you already installed it), and it shouldn't force close. Click 'Install', and if the 'Reboot to Recovery' option below is not grayed out after that then it worked.
3.) Download and install the NB1 modules
On your phone, download the included NB1 modules ZIP file I attached for you, and once that is done you need to reboot. After the Galaxy S4 logo, you'll see a screen that says 'SAFESTRAP: DISABLED' and there will be a little robot. TIP: To enter Safestrap, press the menu button (physical, hardware key) under 'Recovery' at that screen. To continue to Android, press the back key (again, physical) under the 'System' tab. For now, press the menu button under 'Recovery'. Now, click 'Install' which should be in red, click 'Add zips', and navigate to your Downloads folder. Now click on the NB1 modules ZIP you just downloaded. Swipe to install, and reboot. This time, hit the back key under 'System'.
All done!
Now, Android should (and will) boot up, and you'll have working WiFi! If, for some odd reason, you don't have WiFi- do NOT panic! Just search around for the MF3 modules and flash those! All is good, all is good. A lot of this guide was taken from my post about my personal method of SIM unlocking the AT&T Galaxy S4 without the dialer codes or an AT&T SIM. It was just modified a little to work for you.
Remember, hit thanks!

can't boot phone

Hi, I started a thread needing help with my wifi but it has developed into not even being able to boot at all; it stops at the galaxy logo and either freezes or keeps booting. I have gone to the Odin page with all the different things to do and flashed the file to get back to the original rom but that is really where the trouble began. right now the only thing I can do with my phone is get into download mode, I can't even get into recovery. I have flashed a pit file that worked the first time but I don't know if that is part of the problem or not. Can someone please give me some directions, thanks
Also the phone won't boot at all unless hooked up to a power supply, the battery alone doesn't do anything.

More info is needed. What firmware / bootloader are you on? Was it rooted? Did you have a custom recovery installed? What version of ODIN are you using?

Right now, it sounds like you might need to use enewman17's ODIN debrick file.

It is the AT&T s4. To be honest I don't know what firmware I am on, it is the one the Odin page said to use if you want to go back to stock. I never rooted it. The bootloader would be whatever the latest update was for this phone. I can't get into it to tell you anymore. I am using ODIN 10, the latest one. thanks
Well I finally got into recovery and did a factory reset, now it boots into the AT&T white splash screen before it just turns off. I am also wondering if my battery just died for some reason?

ODIN 10? Try using ODIN 3.09 and see if that helps. The latest update would be Android 4.4.4 NJ4 firmware. This link should help you, it will give you root with safe strap recovery though: http://forum.xda-developers.com/galaxy-s4-att/general/guide-odin-to-stock-updating-rooting-t2926642
I meant 3.10, I will try the older version. What file should I flash?

Check out the link I posted in my last post. It should help you get your phone fixed.
I have been there. I went to the very last option which seems to be what I need unless I am missing something.
Neither odin 3.09 or 3.10 will even flash any file now. it either says invalid md5 or fails when it attempts it.
Well, I finally got it to boot into android but it is flaky at best. It is android 4.3 instead of 4.4 where it was initially. The wifi still doesn't work and now the keyboard keeps crashing everytime I do something. The build is jss15j1337ucuemk2 which I know is older than I had before. Does this give anyone a better idea of what I need to do? If I can get a stable flash then can I flash a modem file to fix the wifi? I really need some direction, thanks
Turns out the battery was completely drained which was causing some of the boot problems, I don't now how that happened but I am charging it now.
Well after using odin 3.8* I got it to install some older firmware ending in mk2 rather than the nc1 or nf4 that I had before the trouble. After I got it to boot, I went back into download mode and flashed the modem file and now everything works execpt I had to force stop Samsung keyboard and use swype. I would like to upgrade my firmware but since for a couple of more weeks it won't have a sim card I can't upgrade OTA. For some reason Kies says that firmware upgrade and initialization isn't supported with this model which makes no sense to me. It also says my firmware is up to date
Does anyone know how to flash to the latest firmware without me going through this nightmare again? thanks

If I were in your shoes I'd flash the nb1 tar file in Odin, any vein should work. See this for the tar file http://forum.xda-developers.com/showthread.php?p=56453100. You can then ota to the latest firmware which is 4.4.4, nj4

Download a firmaware for your region from sammobile and flash it via odin 3.10. It will solve most of your problems

I agree. But google has basically all he needs. More so rapidgator
I haven't found anything from Samsung to download. If I flash a newer build, do I also need to flash a modem file and a bootloader or can I just flash the PDA? thanks for explaining this to me.
And can I do a dirty flash so I don't have to lose everything again?
well, now I see that there is no sound. so I guess I will have to flash again.

There's. Something I'm yet to understand. Did you finally manage to boot into recovery? If so, flash a custom recovery (I recommend philz touch recovery) then use it to make complete wipe.
Then boot into download mode and flash latest pda firmware in the compressed file you downloaded. Ps: make sure it's from your region.
May be if you provided me with your region I'd get you all the files required

"Old" I337 Galaxy S4 failed to root and now won't boot normally

I have two ATT I337's and wanted to root them both. The first and newest one worked fine but it has a busted screen and is locked. It was my test run and went very well except for the wifi problem that many others had trying to load towelroot from the net. Btw, it would be helpful to all going forward if someone would edit those instructions to download say towelroot first!!! I found a solution that I will post later.
Unfortunately my second and primary phone failed early in the process. After I loaded NC1_Stock, it would only boot to either the Recovery menu or the Odin menu. I have tried loading NC1 again, tried NJ4, tried safe mode (will not load), pulling the batt, factory wipe (ouch) and then tried emergency recovery in Kies. NOTHING is working. I did notice that the sticker in this I337 has NO serial number! So with Kies I used the serial from my broken one, on the second one. Unlike my other one which has a serial number on the sticker. So I am not sure if this is an older model, a refurb or what.
I must admit that I did NOT check the original firmware version when I started this process.
In any case I am looking for ANY options to get my i337 working again. Are there any other firmware versions to try? (link pls) Anyone? A phone that only goes into recovery or Odin mode is not much fun!
Honestly, I'm not sure what you did with the two phones with IMEI and stuff lol.
You have to back to NB1 firmware and work from there. Follow this guide until 3rd section on whichever phone you can Odin.
Make sure to completely close or remove Kies software. It's known to cause problems with Odin.

I have gone back to NB1 multiple times(see orig post) and I get the same result. How do I disable Kies if I can only get to recovery or Odin menus? No matter what I do, I can only get to those two menus.

I don't see any mention of NB1 in your original post. If you use the guide I linked to, you don't need to do anything with NC1. You flash NB1 and go straight to OC3.
Just to be sure, you're using this Odin (3.09), right? Because that's the one you need. By disabling Kies, I mean just close the program or remove it from your computer. Both Kies and Odin are independent so you don't need Kies to use Odin and vice versa.
OC3
Apologies. I did not notice that you were saying NB1 instead of NC1. I was able to recover by loading NB1. Thanks! I am using odin 309.
I did try going to NJ4 after recovery, but I lose wifi. Where do I get OC3???

Found it in the link from your first post. After reading through the process I am not sure I really want to go to OC3. Any issue with staying on NB1? Is there a more stable 4.x.x release that I should go to?

OC3 is newest Android version 5.0 (Lollipop). Some people say it eats more battery, but I don't feel any difference. To me, it feel more smoother, faster, and much more fluid. Even my father, who is not tech savvy at all, told me it was faster than before. It's as stable as any 4.x.x. I'd say the update is worth it.
The guide feels longer than it actually takes. You only need to follow sections 1-3 if you want OC3 update. Actually only Section 2 Section 3 since you already have NB1 working. Section 4 is optional. You'll be done within 10 minute max. :good:

You did mean section 3 right? "Upgrading to ROOTED STOCK OC3 (Lollipop) using "keep root" method". Maybe I will give it a try. The download took a while and I still need to go the whole G+ thing.

Yep, I meant Section 3 Root your NB1 if it's not already.
You can avoid G+ thing and download the Flashfire APK directly from here.

Pokmemon Go/ Uninstalled Kingroot and derooted boot screen custom & gear icon on boot

Pokmemon Go/ Uninstalled Kingroot and derooted boot screen custom & gear icon on boot
Hi, so a while ago I tried using kingroot and installed it for a little bit and used root to uninstall some factory installed apps like amazon, etc. then when i decided i did not want root anymore. i used the kingroot app to remove root and then uninstalled the kingroot application.
then i downloaded a root checker app to see if i was rooted. i was not.
now whenever i boot up my phone it says samsung and then the word custom with a gear icon below it.
now when i tried the newest version of pokemon go version 0.37.0 it says it cannot run on my device cause apparently it thinks i am rooted.
is there anyway to solve this? other than a factory reset?
I don't think a factory reset would help either.
You'd have to delete every trace of root left on your device, and kingroot probably left some files behind.
Unless you can find them, the most sure method is to flash another ROM (stock) though Odin.
I believe a custom kernel would also work, or the stock boot.img of your current ROM.

The ROM you can get from Sammobile. As for the files left behind, I don't know how kingroot handles those, but to access and delete them you would have to be rooted.

ok, i powered down the phone and held the power and volume up buttons to get into recovery mode and then i selected wipe cache partition. and then rebooted. it seems that has solved the custom and gear icon below on when it first boots up. cause now it shows samsung galaxy s4 which is correct. but when i try pokemon go 0.37.0 it still says this device or software is not supported what should i do now? i heard somewhere that you can use xposed framework module

I already told you that a factory reset does not unroot.
If you want to completely unroot, flash the stock ROM.
If you don't want that, downgrade to Pokémon version 0.35.
0.37 has not even been officially released yet. I mean, I don't even have it on the play store and it's the same for many others.
PS: Xposed also needs root.

You don't need a pit file. And if the files are wrong, the instalation will just fail.
If that's the firmware you had previously, then it's ok.
