I am not sure what is going on here. If anyone could help out, it would be much appreciated.
I am on stock AT&T Touchwiz. I was running the stock kernel and ktoonsez's 5/27 TW kernel with no problem. When I flashed ktoonsez's 5/30 TW kernel, I lost the ability to connect to wifi (when I try to turn the wifi slider to "on," it switches right back off). I cannot for the life of me get it to turn on.
I tried flashing back to the 5/27 kernel and I still can't get wifi to turn on. I also tried odin-ing back to stock, which has the same problem.
The odd thing is that I can still use wifi tethering, so I know the wifi can work. I just can't get the wifi settings to enable wifi anymore.
Just for fun, I flashed the AOKP rom and ktoonsez's 5/30 AOKP kernel, and wifi will work in that rom. I just can't get it to work in Touchwiz.
Any thoughts?
Make sure your baseband and build are the same, ex. baseband MDL, Build MDL.
If these 2 are different wifi will not enable.

Baseband and build are both the same: 1337UCUAMDL.
before you flash do a system wipe so you have a clean slate, then flash rom and kernel and see if that helps, also you may try resetting to default settings from within the os.

I wiped system and then odin-ed to stock and it still didn't work. I am not sure how much "cleaner" I could get it.
Hmm well, it seems like you did everything right, thats really strange.

Yeah. I would understand that wifi was totally dead if if didn't work in the AOKP rom, but it does, so I'm stumped. I may just go over to the AOKP rom since I don't really need the Touchwiz features anyway.
after you odin back to stock did you do a factory reset from within the OS?
1. Open Settings.
2. Select Accounts.
3. Select Back up and reset.
4. Tap Factory data reset.

Odd... My baseband is MDB and build is MDL. I thought baseband had nothing to do with kernels..

It doesnt, i was telling him to look at those because i experienced something similar.
I flashed back to stock and my baseband and build were different, baseband was mdl and build was mdb and i couldnt turn on my wifi at all.

Oh ok... Maybe it was rom related and you probably needed a kernel to fix it (as it did for me).

I started having similar issues today with my WiFi.
Back story: I was playing around in ES Explorer trying to get WatchOn app to show in my app drawer and changed something that apparently shouldn't have and ended up sending my phone into boot loop. It also wouldn't recognize my SD card. After several faiked attempts due to my computer not recognizing my phone I was finally able to Odin to stock, re-root and restore from my Nandroid backup.
Which leads me to my problem. When I try to enable WiFi it just shuts back off and I get a security pop up saying, "Prevention Information - The device has detected an application attempting unpermitted actions and has stopped working. It is recommended that you reboot your device." And gives me an option to rabbit now or later.
After reading this thread I noticed that my baseband and build number were different and I will try doing a complete wipe and Odin to stock. Any other input would be greatly appreciated.
Thanks!

Maybe there is something wrong with the Kernel you are using. I don't know because I am on stock. However, the security message you are getting might be remedied by freezing "knox" and "SeAndoid". It probably wouldn't hurt for you to try it.

Just to update, I did a factory reset in CWM, reset davlik cache, factory reset from within setting and odin back to stock and wi-fi is working.
I'm about to re-root and not install the Nandroid backup and see if it's still working after that.
Final update.
I was able to get WiFi working again. Im not sure if doing this would help anyone else but this is what worked for me.
I did a wipe in CWM, cleared the cache and Odin back to stock. I then updated the software through the phone's setting menu. I tested WiFi before and after the update and it was working just fine.
Went ahead and rooted my phone again and WiFi was still working. Installed CWM again and tried the restore from my nan droid backup again and all is functioning normally.
On a side note, my 64GB SD card is working again also.

Ok, talk to me like I'm an idiot about this stuff, because apparently I am.
I decided to root using chainfire autoroot, and that was successful, aside from a couple weird things like my UCCW widgets suddenly not stretching fully across the desktop, and what seemed like some new lag. I then flashed slimbean. My contacts didn't restore from google or anywhere, and my sd card seemed to be having problems. I then decided to flash blue kaban or whatever, and that straight up wouldn't boot. However, at that point my sd card fully stopped working, and that is the place I had the slimbean zip. So I did not have a working rom on my phone.
So what I decided to do was unroot and start from scratch. I used the method in this video on youtube by qbking
The result is that my wifi is not working and I have a persistent notification that says Prevention information the device has detected an application attempting etc.
Also software version is MDL, Baseband version is MDL, and Build number is MDC. I was under the impression that they would all be MDC and it would automatically push the MDL but apparently I suck.
My ultimate goal is get back to pure out-of-the-box stock so I can start the rooting process over and try flashing something stable again. But abviously the most important thing right now is to get the wifi working and (I think) the Basbeband and build numbers to match. But I don't know. Please help me. Please. I beg of thee.
ok so after an hour or so it pushed the update to me and my wifi is now working, and everything is MDL. The SD card still says damaged and my contacts aren't there. Any ideas on why those two things would be casualties of rooting and flashing?
I've got the same problem after flashing back to stock from some rom. Would you mind telling me how you got the wifi to work and that notification to go away? I'm not getting an update.
Did the SD card problem happen afterwards? Did you do a factory reset and delete data before you reflashed it? Sometimes when you flash over a partial thing system apps get corrupted.
I have actually performed this and had this happen a few times. What I have found thay it does on some devices is will not properly install random MDL firmware(Saw MDL Firmwares In Settings Still Being Reported). So what I found to be the proper steps for me is before installing any ODIN tarballs thatcare firmware based besides rec9eries are to boot into Recovery and wipe "System, Data, Dalvik, Cache and Preload(Dont Know Why All Of Those) then immediately reboot into Download Mode, install tarball and then when it reboots I go ahead and let it go into recovery and do what it wanrs and when it reboots from stock recovery I hold vokume down to go into download mode and if it says Samsung Official/Official for both options then you are set but if not then I reinstall tarball while I am already in Download Mode again. It happens literally every time I ODIN back to bone stock. I have had to do it at the most 2 extra times after the initial ODIN install.

Now, I also do go ahead and after initial install of tarball go into OS and if I dont have working wifi then I go ahead and do an FDR while I am in the OS just in case even though should helo whatsoever lol then start going to download mode to check Recovery and Software Status.

Just got a brand new i9505 and the Wi-Fi won't turn on.
When I hit the Wi-Fi toggle it goes on for 1 sec then back off. I have tried a factory reset etc but just can't turn it on. I can't believe it's actually faulty. This is my 2nd faulty S4 out of the box. I brought a i9500 about a month ago and it keeps freezing & rebooting after a minute of use. Unfortunately I can't send that one back as it has a custom Rom & there is no way to reset the counter. I gave up on it and through it in the draw.
I decided to get a new one but went with the i9505 this time. How can I have so much bad luck. Is the S4 that unreliable?

I had the same problem with a custom rom wifi won't turn. All i did was change the kernel.

Instead of clicking the wifi toggle, why not try to go into settings and mobile networks
and turn it on there.
Good luck!

I,m using KERNEL][INT'L][AOSP/TW][6/10/2013B] KT-SGS4 - MDM - KTweaker
You can try booting into recovery and clearing the Cache and Dalvik Cache to fix the wifi. It's worked for me and other people on this forum.
i also have the same problem on my S4, basically the wifi wont turn on, i already did flashing firmware, wipe cache and dalvik cache but still the same thing
yeah same here. I've been researchin and flashin almost a month now and nobody seriously nobody could fix this issue. shame. i hate that it happened suddenly and without a warning.
Happened to me also...This is how I fixed it (accidentally of-course ):-
---First mistakenly dirty flashed stock ROM via odin v 10...That was an honest mistake
---Couldn't start my phone due to it...FC messages were appearing again and again...
---went to download mode...directly flashed CF-Auto Root and TWRP from ODIN again...
1) Wiped everything from TWRP
2) Went to download mode and flashed Stock ROM via Odin.
3) WiFi didn't turn on even in Stock ROM (came as a shock to me)
4) went to download mode...directly flashed CF-Auto Root and TWRP from ODIN again
5) Flashed "Doctors-Amputated-V3" and "CWM-Modem-I9500ZCUJOH2_2" via TWRP.
voila !! WiFi working again in the new ROM :laugh:
Hi mate,
Could you please explain what "Doctors-Amputated-V3" is? A custom ROM?
Basically, I have flashed the stock Samsung image and a previous backup, and still have issues having used PryFi. I'm trying to get my WiFi back to stock and probably flash a kernel or revert to whatever is most compatible, so as to stop my device rebooting...
Could you please recommend a kernel or modem to flash, and then the best kernel or modem to flash afterwards, in order for maximum compatibility. My S4 has always been stock rom, just with Root.
Appreciate your time Prateekgupta!
Cheers,

---Yes its a custom ROM...
---PryFi breaks phone's Wifi every time you use it...I've given up and uninstalled that app....Flash stock rom again through ODIN...
---The process I described didn't solve my problem...My wifi worked only for 20 minutes...After that it went back to grey...
---No software trick can help if your Wifi and Bluetooth both are not working...Its basically the Wifi antenna/IC that needs to be fixed...Its a hardware issue...
Not sure on this way. Running Stable 4.2.2 Google Edition and had 0 problems until a few hours ago. Went out after dinner, tried to google a phone #, but had no data. Rebooted (just for kicks), and still nothing and no voice. Trying to make a call I get "Mobile network not available". I tested using my daughters G3 and worked perfect so I know it's not that.
So, I would like to try 1 of 2 options, open to either.
1. Revert to the stock 4.2.2 and wait till the 4.3 comes around
2. Upgrade to test a newer ROM. I am reading up on the MF9 but a little unsure, if I am running an MD9, can I simply flash a newer MF9 ROM onto what I have?
I don't want to brick this phone, so what's the best way to move forward and hopefully fix this issue.
Thanks

Thanks. Looking here http://forum.xda-developers.com/showthread.php?t=2303917 there are plenty, but as I said, I am still on the MDL ROM, so I would assume pick an MDL touchwiz, no?
Actually I have a blu-Kuban (touchwiz) nandroid, I restored to that backup, and had the same issue. No voice, and the PRL, etc. all failed to update. I am downloading the stock deoxed MDL, and will try a wipe/clean install of him.
Tnx again

I'm actually running Blu Kuban as well and I do not have this issue. Try turning the cell data toggle off and back on. Also, make sure you aren't in airplane mode. I have noticed that sometimes the toggle is on while the airplane symbol will not show in the status bar.

Thanks, but since I did try a restore, that would ensure airplane mode was not the case as I don't use it nor would I have 2 ROM's both doing the same thing. I did do a wipe/restore with no luck, so now going to do a wipe/flash. If still nothing, will have to resort to going to stock and taking it to a local sprint shop!

if restore fails.. try ##786# > reset on stock rom. you need your SPC/MSL for this.
if the 786 reset fails.. let me know in about device > status if your phone number is still listed.. and what PRL is shown.

Hi all,
I recently installed the newest build of Slimbean. I am having a few issues: I am unable to play any media... Music, videos (youtube). My phone app does not work. I cannot receive nor send any calls. And my phone produces no sounds at all.
I tried installing build 7 to see if it was an issue with the build I was using... didn't help.
Internet and wifi work without any problems.
Galaxy S4 i337m
Baseband: I337MUMUAMDL
Version: Slim-4.2.2.build.7-OFFICIAL
Build #: slim_jfltecan-userdebug 4.2.2 JDQ39E eng.blk_jack.20130706.15730 test-keys
Any ideas?
Thanks in advance

I did just that... But it's a bit of a story.
I had just fixed another problem I was having yesterday. Was getting stuck at the S4 splash screen right after powering on the phone. The problem was caused by TWRP 2.6 and formatting /data partition. Long story short, I installed CWM and used it to do a full wipe/format of partitions and then was able to install ROMs, restore backups without issue.
So today, since everything was working, I decided to flash a new custom ROM (which I installed) and the MG1 radio. Wasn't having any luck with the radio. Finally, I was able to flash a radio via mobile odin, but then I soft bricked my phone. Got stuck at the S4 splash screen (same issue I had yesterday, but this time, a different cause). So was troubleshooting it all day. Tried to go back to stock, no luck. Tried to restore the stock backup I had, no luck. Only thing I could do was install custom ROMs at this point to get into my phone (i.e. Slimbean, FoxHound, etc...). But, at this point, although I could boot into Android, I had no sound at all and couldn't play video. So after hours of trial and error, I installed CWM again (replacing TWRP 2.5.0.2), did a full wipe/format and tried to install a stock ROM. No luck. Still was hanging at the S4 splash screen. Then I tried to install this ROM again which I had luck with in the past; |ROM| |★VLUAMG1★| |CANADIAN||i337M||STOCK||ROOTED||July.26.13|. But his instructions said to install a wifi fix or fear soft bricking my phone. So I installed the wifi fix, but selected the wrong file (I know, stupid. Done a lot of stupid **** in the past couple days with this phone). Now, after the phone rebooted, I would see the S4 splash screen for a split second, and it would auto load into download (odin) mode. Couldn't get into recovery at all. So then I decided to flash one of the stock ROMs I tried earlier that didn't work, but this time, SUCCESS!!!!! Phone was booting and all sounds worked. I could make/receive phone calls as well... Everything seems to be working fine now. I find it funny that flashing a wifi fix that I shouldn't have seems to have fixed my issue in a sense. Since it allowed me to successfully flash a stock ROM. So I am making a backup of the stock ROM and will decide what I'm going to do from here.
Holy goalie!!! It's been a very vexing couple of days.
Nice that you got it all worked out, I've found out that if your "status" is custom, it will sometimes give you problems when flashing a "stock" rom via odin.
So what I always do when reverting back to the stock rom, I use triangle away to clear the flash count and make my phone back to "Official". If you want the steps to do this, let me know, it's not hard, but there are crucial steps to get this right!

Ever since I rooted my Verizon S5, I've had a strange issue..
It happens every time I flash a new ROM using Safestrap (of course.)
When I go in to settings and try to click or unclick a checkbox, it doesn't work. Or for instance if I change the GPS mode from Power Savings to High Accuracy, it doesn't change. It just stays with the previous one. But if I reboot, and go back to that setting, it will be changed. The same goes for if I'm trying to allow installations of unknown sources... I'll go in, click on the check box to allow unknown sources, but it won't come on. Then I'll reboot the phone, go back in and it will be checked on. If I go in to Safestrap and wipe Cache and Dalvik, it works just fine for a few minutes, but then goes back to not working.
Anyone having this issue or know of any fixes?? Any help is greatly appreciated!

I've been using a custom ROM slot, I've tried to set it up in the stock slot but I can't seem to figure out how to wipe the stock slot. Is there a certain way to do that?
By the way, I flashed Optimal ROM as soon as you released it, best build yet! It's fantastic!!

You need to be using the stock slot. There are known issues with custom/rom slots. But yeah, you'd just wipe data/factory reset the same way. Then flash the ROM and firmware (if needed).
Glad you're enjoying the ROM!
