[Q] S5 continous rebooting after wifi activation - Galaxy S 5 Q&A, Help & Troubleshooting

H!
I've just upgrade my S5 to lolipop, and now, I get a continous reboot when wifi is on.
The problem, is that now, I can deactivate wifi, because when I start the phone, and just after input the pin, it restart again and again.
I tryed to make a cache wipe, but it don't works.
Any idea?
Thanks!

.
I have the same problem after updating. I wiped the Cache also, no luck..... tried factory reset.... no luck. Anytime I switch on the WiFi it I just reboots, even in safe mode. I have run out of ideas! Any help would be appreciated.

[Q] Wifi stopped working? P6810

Hi all!
Started up my 7.7 yesterday and since then i'm not able to use my wifi.
It finds my router just fine and connects but the bars are gray and i don't get any connection to say for example, www.google.com , market etc.
Tried to do a factory reset, didn't work. Also downloaded the firmware and flashed through Odin with no success.
Anyone encountered the same problem? Is there a fix?
*Edit*
Strange. Held Power+Volume up, wiped cache and did a factory reset from the recovery. Now it's working fine.

[Q] Can't access "data synchronization" in settings

Hi all,
A few days ago I started to have a problem with data synchronization in settings, mainly whenever I try to open it the phone restarts, leaving me without possibility to switch on/off data sync. I've tried with widgets but to no avail.
What I did after the first time it occured, was just a factory reset from recovery. It worked but after a few hours the situation repeated. I really don't want to reset it again... I've tried to fix permissions from recovery but it didn't help.
Any thoughts ?
I have a 2.1 stock ROM with enabled fastboot and clockwork mode recovery. The phone is rooted now, but it happened both when it was rooted and when it was not.

[Q] Reboot & Power Off Problem

Hi,
I'm using SM-G900f with Fusion ROM.
I decided to reboot my device which normally worked without any problems. But this time it got stuck on black screen and I couldn't turn it on/off. I tried like 3 time and the same thing kept happening. Even when I just turn off the device it's still stuck on a black screen and doesn't turn off unless I remove the battery. I would really appreciate if anyone knows a solution for this or has information on what I'm dealing with. I tried wiping cache and dalvik cache but didn't help.
Thanks.
Got no answers here so I tested wiping cache/dalvik cache, system and install the same ROM on top with fusions TRWP.
I can now reboot to recovery atleast which lets me reboot/shutdown but I still can't reboot or shut it down normally.

[Q] Continuous, consecutive reboots.,doesn't happen in safe mode any fix?

Hi!
I've got an N910C with Lollipop ( I did a factory reset after upgrading and cleared cache) . It randomly decides to reboot, and will keep doing so. After a reboot, I can use it for about a minute till it reboots again. Booting into safe mode fixes it temporarily and it stays fine after safe mode, a regular reboot doesn't help.
I'd prefer not to factory reset, and would like to find the cause (app/sd card? Sandisk 8GB btw)
Cheers, thanks!
My N910A does the same thing except the times it reboots can vary from a minute to an hour later, but it reboots a lot.
Doesn't happen in safe mode only regular boot mode. That tells me it's either an app or SD card.
I swapped SD cards and same issue. I wish there was a log I could look at to see what app is running at the time of reboot, but haven't found any logs that have that info.
I'm stuck and running out of ideas.
Try factory reset again man and remove Sd and try to boot it
You can identify where the problem come from

WiFi not working keeps turning off after factory reset

Hello, I did a factory reset of my P9 Lite VNS-L31 (VNS-L31ITAC555B367) and after reboot I'm not able to turn WiFi on. When I try to do so, the switch goes ON and OFF instantly after couple of milliseconds.
I tried to solve the problem by using eRecovery, so I rebooted into eRevoery but it also failed to run the WiFi - it just reboot short after it tries to start the WiFi.
Have any of you ever expereienced such a problem?

Hi, try the following :

2. Install Service ROM , download here
Instruction can be found in 'ReleaseDoc' folder.
The process will erase all your data!
