[q] urgent help needed - Galaxy S 4 Q&A, Help & Troubleshooting

I tried to flash a rom and it didn't go so well due to the fact it was for Verizon S4 only and I missed that,
anyway I decided to go back to my recovered stock TW rooted Rom and everything was fine until... my WiFi stopped working, just wouldnt turn on then was asking me to reboot my device?
after a bit of searching I found out to just revert back to official stock firmware.. BUT
for some strange reason and for the first time ever, when I reflash the official stock firmware it stays as custom and is all buggy and crashes a lot. could this be because I am flashing an official stock that is less updated than my rooted TW?
someone help me cause it's really starting to aggravate me!
thanks!

When you flash the stock, do a factory reset. Any if it does not work, repeat the procedure (reset/flash/reset). But make sure you have the right stock (I suggest to take it from sammobile). I heard of up to 7 tries before success...
good luck

@JacksonPa93:
Can you check if you actually have this problem (WLAN/Bluetooth doesn't work and random crashes with reboots):

fixed!
I think I've solved it by what was mentioned about factory reset>flash stock
Took me 5 times to eventually get it working..
thanks guys

Stock Everything

What I want to do is install a stock non rooted rom, kernel, and recovery. I am not sure how to change recovery to stock either is it like flashing a rom? Please give me some links for these I can't seem to find them, besides the stock kernel I found that.
----------------------------------------------------------------------------------The reason I want the above is bellow, if it matters.-----------------------------------------------------
My phone is about 95% broken.
Before, every rom/kernel combination would randomly restart, it was my phone it self I believe.
I went to a stock rooted rom, but then it restarted, and my lock screen worked, yet my home screen was black all i could do was slide my status bar down.
After that i restarted my self and then it got stock forever on the screen where it says Samsung galaxy s4.
The 5% working part is my recovery, for the most part.
I keep having to do a full wipe, not just system wipe otherwise it says error unable to mount preload or i/o or a few other things, I have to system wipe before every rom attempt.
I tried several popular roms such as sacs and triforce and a few other roms and all the kernels also.
The phone will turn on, work for a little normally, then crash again and go into the infinite loading screen where is simply says galaxy s4.
This phone is only 3 months old, so I want to take it back to sprint being completely stock so they give me a new phone.
I need links to files I need, and if i am forgetting to change anything back to stock please let me know. Thank you.
I replied to you in the newbie thread, but to return to complete stock download the latest firmware from here: http://www.sammobile.com/firmwares/ and install it with odin. Do a factory reset before and after install to make sure you have cleared out what ever is causing your problems. After this process you will be completely stock and unrooted. If you are still having problems after this it is probably hardware related.

Slimbean 4.2.2 Build - media issues

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
Update: Any ROM I install... Phone and sounds do not work.

I'd Odin back to stock and see if you still have the issue. If you do it's a hardware issue.

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!

Unrooted S4 to 5.0 Lollipopm cant connect to wifi at all

Hi I need desperate help
two days ago I went from CM11 to S4I9505 Google Play Edition ROM 5.0.1 and everything was running perfectly. Today I used an app known as "ROM Installer" to flash TWRP easily which it did but I couldnt go back to normal menus and it kept on booting back to Recovery. So I wiped everything and installed the same ROM as it is in my External SD. It was successful but it still would boot to recovery and nothing would work. So I thought my option was to unroot the phone. I used the XDA Unroot/Unbrick guide and used an Android 5.0. Lollipop firmware to flash the stock firmware (second time every using Odin, the first was disastrous and I hated it). I flashed the official stock and it is running but cannot activate WiFi what so ever. It just refuses to toggle. So I reflashed the stock firmware again and it still doesn't work. I was thinking of somehow downgrading to KitKat, use CM Installer which is how I initially rooted the phone and revert to a CWM backup that I made before I flashed the S4 GPE ROM and start over. However I tried using that CM Installer and since im on Lollipop it would refuse to work and I really wanna get back to how everything was before :'( I really dont know what to do (No warranty or anything on this S4) All I can do is make calls and texts. Please help!
fixed!
I've fixed it! Its all back on stock with the all that bloatware and useless features only problem now is whether there is a way to deleted this thread

lag, freeze, restart after 6.0.1

hey guys, today i bought a used NOTE 4 for my mother, and when i checked the version it was 6.0.1...so i wiped everything and restarted the phone to get the best performance....but the phone lags and freezes a lot, especially in the camera, and it keep restarting all the time....what should i do? should i try to flash another FW through ODIN?
You mean you used the Factory reset option? That's not a full wipe, just resetting stuffs. And yes, you know the answer, wipe everything from a custom recovery, then flash stock MM ROM (always latest) via Odin. Earlier versions did have a reboot problem though, and lags here and there, but that's expected, but the last release, PE1, has got rid of all those problems, its a very good release already, and I am sure upcoming releases will only make it better. There are no major bugs at all, I don't even find any minor bugs except the need for a separate app to clear default apps selection.
Best of luck.

the phone is stock, it has the stock recovery, and i have the PE1 version, the exact name is "MMB29M.N910FXXU1DPE1"...and still got a lot of lag, freeze and rebooting.....is there another version?
EDIT: ok, so i flashed another MM through odin ( first time it gave me a fail) and then done a factory reset, now it's so much better, maybe not as smooth as my S6 but really fast and smooth enough...thanks for the help
EDIT: today the phone started to shutdown completly....not reboot....and you need to press the power button 10 seconds to reboot it or turn it on...is there any advice?
Guys . Ib tead the whole thread over last few day had wake lovk runnimg last couple weeks. Lastnight used kies for reset and it crashed half way.
I then used odin 307 and went back to stock 501

Just download and install Wake Lock from Google Play Store. I had the same problem and more. Once I installed Wake Lock (on a fresh install from Android 5 up to all the 6.0..1 builds) phone doesn't shut off or freeze. Most importantly no more Boot Loops..

Back to stock rom, hanging when placing call, no sound etc.

Hi there
I have recently picked up my old S4 since my OPO screen broke. I was annoyed with the buggy CM 12 nightly it was running and tried installing the newest CM 13 nightly. It gave me no signal and I decided to try to revert to stock, following the guide Unroot/Unbrick, Flash official stock firmware on S4. Applying the I9505XXUAMDE_I9505OXXAMD8_NEE 4.2.2 stock rom through ODIN was a breeze but after booting i realized it had no sound.
Also placing or receiving calls makes the phone hang, even occasionally reboot, and sometimes a window with "android.phone.. app" or "process system is not answering" appears. For example also not possible to record video.
I did both factory reset and wipe cache in bootloader, but when wiping cache I get the lying down android with red exclamation mark for a few seconds then reboot.
I then tried to reflash above stock rom with repartition (pit file) and the problem remains.
I dont suppose it is a hardware problem since it started after I flashed new rom. It seems like some audio related software issue that I cant seem to get rid of - can anyone help or should I just give up and get another phone?
Thanks in advance, sorry for the long post
Try flashing a newer ROM.
The guide used is pretty old I guess and should be used only as reference.
What was the initial stock ROM your device had?

I already tried rerooting and flashing back to both CM 10.2 and newest CM 13 nightly from philz touch recovery. Both with the same problem when placing or receiving a call. But sound was working..
I don't know the exact stock rom the phone came with but seem to recall it was 4.2.2 as I have installed now.
Is there anything else that can be flashed back to original? I read several posts talking about a modem reflash for fixing audio issues but I suppose the stock rom should contain the modem info already..?
I specifically went for the oldest rom, since the guide said that once stock 4.3 is flashed you cant revert due to new bootloader. And I was hoping to revert to being able to use OTA updates since I plan on gifting the phone to an even more tech illiterate than myself.. Is that going to be a problem if I just flash for example the newest 5.0.1 stock rom?

Downgrading causes problems in the first place, that is why it is recommended to flash the same software as it originally had.
As long as your status says "official" in download mode, you should be able to still get updates. Although who knows for how long.
I also recommend using the latest TWRP recovery. PhilZ and CWM are outdated and can cause problems with newer ROMs.

I will try to install TWRP and the newest stock firmware and see what happens. Thanks
Ok, upgraded to latest stock rom and everything works!
No idea what was wrong specifically though.. Thanks for the help!
