Wifi not working + recognized improperly by computer - Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot

I've got the SGS4 and I've run some of the latest updates.
The build is: JSS15J.L720VPUEMK2
The baseband is: L720VPUEMJA
The version is: 4.3
The software version is: L720VPUEMJA
Whenever I try to turn wifi on, it automatically shuts off and I get an error message stating:
"Security Information
The device has detected an application
attempting to perform actions that are not
permitted. These actions have been
blocked"
Now I know that there is a lot of this going around, however, I was hoping to just reload a stock firmware of an earlier version and get rid of this crap for now. However, when I enter download mode, the computer sees the Galaxy S4 as a "MSM8960" in device manager and will not install drives. I've got Samsung Kies, I've installed the USB drivers. Nothing is working.
Anyone have any advice?

I tried a hard reset. Still nothing.
This is absolutely frustrating.

Use this :

It's going to return you to stock MK2
Also flash this through Odin instead of Kies...

Can't Update Firmware with Kies or Odin - HELP

Ok, the phone is great, but the hassles of upgrading the firmware compared to my old HTC Hero - NIGHTMARE!!
Kies either fails during download with corrupt files, or then consistently get the DLL Load Fail error message - and yes i'm running it as Admin ... and have tried disabling AVG ... firmware recovery also fails ... rubbish, so gave up ...
Tried Odin, it all appears to do it ok according to the Odin screen, reboot phone - check the phone status for firmware version, exactly the same as it was before.
Have noticed on the Odin mode screen it says:
Custom Binary Download: NO
Is this right/normal ?!
HELP - I cant update my firmware in any way from my KDD version ...
While this may not help you, I can contribute my Kies experience:
I had the same problem (DLL Load Failure after firmware download) on two of my computers (Windows 7 SP1 x64) as well. After a few tries (including computer restarts and Kies reinstallation), the problem spontaneously went away - without any preceding configuration change I can remember.
If you continue to have firmware update problems and don't want to resort to ODIN you could try if a firmware update via Kies Wi-Fi (Home Screen -> Settings -> Wireless and network -> Kies via Wi-Fi) is possible.
I really don't understand why this phone can't update via cell network/wifi like HTC phones.

Do not update 3.2 via Kies, still have problem

what the hell is Samsung doing? I did not update last time with broken firmware and I tried this time with kies.
Now the problem came again.. It only appears Downloading... Do not turn off target and in Kies , it says fail to convert into safe mode...
Now Tablet stayed at the screen with "Downloading ... Do not turn off target!!!" No any response!
-------------------------------------
BTW, I never rooted.
Update. Thank you for everyone in this post for response.
After google from internet, I found a solution.
1) first, after you had "Downloading ... Do not turn off target!!!" screen, Please do not panic ( I did when it happened and really said f*^@ word to Samsung..forgive me...).
2) Press power button + volume down, and hold until it turns off.
3) say "god bless me" or "Mom, please save me." and press whatever combination of buttons you can.
4) It suddenly reboot after that and please use OTA to update. not kies.
5) as far as I can tell, works fine now. However, connect to Kies with wifi does not work.
Were you on a custom rom prior or rooted? If so, did you reset your tab to factory before doing the OTA?
Get back in recovery and flash your back up. If it fails you will have to ODIN your rom in
No problems here using kies, I was only rooted though and I still have root
Do I have to be connected to a PC to get this update? Isn't wifi enough?
You can use wi-fi for OTA update. OP's issue is that even though the tablet went into Download mode, Kies still didn't think it is in download mode. The firmware update hasn't even started to push down to tablet yet.
Based on the earlier problems, you're better off using Kies. If it fails, like it did for OP, it's smart enough to know that and when you disconnect and reconnect the Tab it should automatically go in to emergency recovery mode. What happened to OP happens occasionally with Kies updates. A lot has to do with the PC it's running on and what else is running on that PC. Kies is far from perfect and I'm guessing OP's issue isn't with the new ROM it's with Kies.
I didn't get the update OTA, but just updated with Kies. Had to re-flash CWM and root, but everything works just fine.
Changing to another USB port solved the problem for me. The drivers for the download stage to the tablet could not been loaded for the port I was connected first.

exactly the same problem. no solution for me yet...
I repeat this: if you think Samsung's firmware and firmware updates are buggy, Kies is even worse.

Quite true. Kies is terrible. My Galaxy 10.1 wifi won't connect to it at all -- it just sits there attempting to connect. No indication of what's wrong, no log files, nothing. I wasted over an hour last night trying to figure out what was wrong -- removed all "ghost" USB devices, installed Intel INF driver updates, de-installed all active USB hubs & devices, etc.
I even updated Kies to 2.1 ... nothing. Very frustrating.
still no luck with upgrading with kies. it connects to tab, downloads the update to the pc,
the tab goes into download mode in order to install the update, and then connection between kies and tab is lost....
i have the latest kies, i have the drivers, i tried another usb port, i have done a factory reset, but still nothing.

[Q] How do I unbrick my galaxy s4???

Ok. So here's what happened. I wanted to root my verizon galaxy s4 and put stock kitkat on it. It was on 4.3. So I rooted it. No problem. Then I tried to put on CWM so I could flash AOPK. But, once I put CWM on, I could not get it into recovery mode. It said that unauthorized software was on my device, not approved by verizon. The only way I could turn on the phone was to put it into download mode and then hit cancel. I wanted to unroot the phone at that point and try again. Also with downgrading it. So I downloaded ODIN and tried to restore my phone to samsung stock 4.2.2. So I tried it, it worked for a while and then ODIN said that it failed. Then when I turned on my phone, it gave me a message saying "Firmware upgrade encountered an issue. Please select recovery mode in Kies and try again." So I opened Kies, connected the phone, and tried to do emergency recovery, but it did't recognize my device. So I selected firmware upgrade and instilation. It downloaded and everything but it said "this devices version cannot be updated." So now I have no idea what to do. I can only go into download mode now. Please help me! What should I do?

Not an easy one this one, but can be solved.
First step: get the right firmware from SamMobile. (phone/operator/country).
Uninstall Kies (and USB drivers).
Reinstall Kies.
Obviously, phone removed all the time form PC!
Shut down the phone (it should be fully charged before, using the normal power adaptor).
Get phone to download mode. Still not connected
Connect phone and wait for the drivers to install.
Start Odin and flash the right firmware (watch for the blue button in Odin, it means the phone is connected OK).
IF it does not work, try another USB port (maybe even a different computer).
If it does not work the first time, in spite off all the above steps successful, don't despair. Shut down the phone (keep pressing power button) and restart in download mode. Repeat Odin procedure.

[Q] [Help] Phone only boots into download mode no PC recognition

OK, I will try and recap everything that I've done to the phone in he past couple of days. The short is my phone will not go into recovery mode or boot up. When I try, I get a black screen and the LED is a solid blue (blue light of death (LoD))? Anyway, I can boot into download mode just fine which would lead me to just Odin back to stock and start from scratch, HOWEVER, I have tried 3 PC's and the original USB cable straight out of the box (never used) for my Tab 3 and S4. I have tried several other cables as well. Here's the sequence:
- I was on TriForceROM 5.4 MK2
- Flashed Unknonfofce's NAE Modem via Odin
- Flashed Negalite NAE 4.4.2
- Found out I had no phone
- Flashed SlimKat and still had no phone so flashed back to MK2 Modem via Odin
- Phone worked fine and wanted to go back to TW so back to Negalite
- Phone worked fine except USB storage would not work and PC wouldn't recognize it (no MTP no nothing, not even the 3 button menu in About Phone>Storage)
- Flashed stock MK2 Rom from Unknownforce, still no USB and no PC recognition and Modem and Baseband were gone
- Flashed MK2 Modem through Mobile Odin and it booted to download mode
- I held the power button for 10 seconds after it sat for a while and here I am
All installs were clean wipes through CWM 6.0.4.4. I updated all the drivers on every computer to the latest from Samsung's website from 6/24/2014. I tried the battery pull trick. While my phone was on my Qualcomm and it was set to MTP. I am at a loss. Is there a fix to get my PC to read my phone in download mode? Then I can flash stock. No recovery, no bootup, just download mode and can't be recognized by PC. I've searched for 2 days on many forums and no help. Help?!

Bump???
We need your exact model number. (Found under battery) ie. L720 or L720t. If its the t varient than thats your problem. Youve been flashing regular 720 firmware. Need more information to help. The last android version you've updated to would help too. And i mean stock updates. Ie. Did you root/rom directly after buying no updates? If its new (2014) then it should be 4.4.2..
