[Q] Network related issue rooted S5? - Galaxy S 5 Q&A, Help & Troubleshooting

Hey guys. Long-time lurker here. Usually try to solve my problems on my own but.... I'm at a complete loss here. I have a Galaxy S5. I was running stock rooted 4.4.4 earlier today. Suddenly, in the middle of the day, I was completely unable to access the internet in any way. Both data and Wi-Fi were non-functioning. They showed up as connected, but I couldn't access anything using either. When I got home I decided I'd try to update to lollipop, see if that would fix it. So I used Odin to flash to 5.0. The problem still has not been resolved. It's actually worse now. My signal goes on and off indefinitely. I have no idea what to do; I've tried everything I know to try.

[Q] Crashing / rebooting on wifi connect after ICS update

Installed ICS fine using Acer_AV041_A500_1.031.00_WW_GEN1.zip from here: http://vache-android.com/v1/index.php?site=files&file=151 , renamed to update.zip, stick it on the root of the SD and powered up with vol down.
Have struck an issue though: following the update my a500 reboots back to the android boot animation as soon as it has established a wifi connection. As long as I leave wifi turned off it runs fine. I don't think it's related to this particular package though, a bit of googling has revealed others who updated using the OTA and encountered the same issue. The only way they've found to resolve it is a factory reset. Ugh!
Anyone have any brighter ideas before I take the plunge and spend the rest of the weekend downloading apps and re-configuring my tab?
I am having the exact same problem. Did the upgrade the the update.zip that was released and worked fine for others. Mine runs fine until wifi is turned on, then it reboots. I am only able to stop the reboots is by turning off wifi, obviously not suitable for. Anyone find a solution yet? Glad to see I am not the Lone Stranger here.
+1 here... strange issue. Got the OTA btw.

Galaxy S4 doesn't work properly anymore.

To preface the current issue with my phone, I guess I should probably give some history of what I've done to it. I got my S4 around November last year, where I kept TouchWiz for about a good 3 months. At the end of those 3 months, I downloaded and installed CM KitKat using their easy installer and it worked! However, when Lollipop came around, I got a little impatient and decided to get CM12 using Antares version. Initially, I noticed there were a few bugs/glitches, but ignored them for the time being. As time went on, it became increasingly aggravating and so a few dayus ago I tried to switch back to stock TouchWiz. When I was setting up the phone, I noticed that the wi-fi would just not turn it. It would stay at "turning on" for a very long time with no sucess. Thus, I decided to switch back to Antares version of CM, but now there were a few issues: service was VERY spotty and the piece de resistance: no sound at ALL, and youtube would never play videos. I searched around and saw that using the Sound Recorder would give me an error: "Internal Application Error. Microphone may be in use." Now I'm not the most techy person around and probably should not have been messing around with my phone, but now all I want is a properly working phone, doesn't matter if its kitkat or lollipop. Your help is greatly appreciated. (If you need to know more info, go ahead and ask, because I'm very new to all this) Thanks!
If you want the stock ROM back, flash it twice using Odin. General consensus here is that you need to flash the modem twice in order for WiFi and cellular radios to work properly. Flashing the ROM twice will do that without having to track down just the modem file and trying to flash that.

Unfortunately, it doesn't seem to be working :/ When setting up my S4, it's still stuck at turning on the wifi
I switched back to Antares CM, and everything works fine except for sound/microphone (to my knowledge). Would there be any way to fix this?

[Q] Samsung Galaxy S5 SM-G900W8 Running Omega Rom V17 Reboots when WiFi Connects

Not sure if this is the place to post this question, but I've been searching everywhere and I haven't found anyone online who is having the same issues as me.
I installed Omega V17 (for G900F) on my Rogers G900W8 S5 a few weeks ago (didn't choose to use the Omega Kernel) and it seemed to work OK, but it seemed to reboot randomly (all of a sudden when I'm in the middle of doing something, the Omega loading animation would appear). I didn't update my modem, as my phone was reporting that I was already using version VLU1BOC1. I have been trying to find out what has been causing the issue. I reinstalled Omega, tried removing all apps, but it would still crash.
I finally started to notice a pattern while at work. When I would walk across to our other building, it would always reboot. The only thing my phone would be doing when walking across the parking lot would be disconnecting from the WiFi in the one building and connect to the other. I suppose the other times when it would reboot where when the phone would, for some reason, drop the WiFi connection and reconnect (or I'm assuming that's why it reboots when I'm stationary).
When I did the install, I wiped both caches and did a factory reset beforehand and it seemed to install fine, so I don't think it is an issue with the Omega install, but I did try installing Cyanogenmod and it has been fantastic (stable and fast). I would rather run Omega for Touchwiz, but it keeps rebooting and it's pretty much unusable in that state. I noticed that there was a new version of Omega (V18) for G900F so I was going to try that version to see if it might work, but I just can't at the moment (I should be able to in the next couple days and will report back with an update).
I was wondering if there is any way to confirm what is causing the Omega reboots, and if anyone else has seen this issue before?

NF910F Random reboots/power failure

Good evening, just a quick ( I hope) question
Recently came from stock rooted 5.1.1 to a 6 rom.
Ever since then my phone lags then shuts down, sometimes reboots sometimes not. I put this down to the rom. However it does it on every single one I have tried. It is also doing it on stock firmware flashed via odin and rooted via cf auto root, any ideas? Hardware issue? faulty bl? Currently on the unofficial cm12 (5.1.1) but still having the same issue though not as badly. Any help would be appreciated.
Also, youtube is how shall I say, funky. Some videos play fine, others say network error. This is on both wifi and 4g. Again, only recently is it doing this which makes me think software rather than hardware issues

SM-G901F WiFi Pemanently Switch Off

Hi All
I have an issue with my S5 Plus (G901F) a few days ago I rooted, TWRP and installed the stable MM ROM from Tkkg1994 and have been happily using my phone. This morning while I was opening the Gmail app the device rebooted and when it came back up I noticed WiFi was not on. Pressing the quick menu WiFi button turns it green for a second before going back to disabled. Likewise going to into settings - WFi and using the slider does not work either, it just goes back to off.
So far, I have wiped ART/Dalvik, reflashed BL and Modem, factory reset. Wiped the whole device and redid everything including diffrerent ROM's on the same BL/Modem (CPE1) and have the same result.
Everything else works, just not WiFi, I should also add I have tried with and without the SD card and disabling/enabling other radios (GPS/BT) in different combos has not worked either.
Has anyone come across this and can they suggest next steps?
I'm currently downloading the stock ROM that came with my phone to see if that helps.
Cheers
Stock ROM did not help.
Did you find solution? I have recently started to have same issue with same device.

Probably not. The S5 seems to suffer a lot by such issues. I bought mine 3 months ago in a shop. It worked for about 2 months very well. Then all of the sudden it became hot in my pocket so i had to quickly remove the battery. After this the device suffered by ocessional reboots. Nothing helped. Even trying to reflash the stock firmware by trying several Pit´s.
Finally got a replacement as obviously either the RAM or the CPU got defective. The other phone lasted for one week as the wifi module got defective there. Nothing helped either. Now it´s my 3th S5. This weekend my flashlight and camera stopped working. Fortunally got this fixed by reflashing the stock firmware.
Honestly I like the phone but it seems to be quite buggy. Never got such problems with my old S4 and am thinking about going back to the older device.
dude try flashing 4 files flash through odin
