[Q] WiFi won't turn on?!?!

Hey i've had my S4 since the day it came out and its worked perfectly I used to run a custom rom but ive decided to go back to stock rom. I did and apparently that was a terrible decision because now the wifi wont turn on. When i click the wifi button it goes light green for a split second then instantly back to black and it pops up with a message in the notification bar saying "The device has detected an application attempting unpermitted actions and has stopped loading. To protect your device, it is recommended you reboot." I have rebooted several times, taken the battery out for 2 minutes, factory reset, cleared cache and dalvik, deleted all the files in data/misc/wifi and still no luck. I am rooted but this occurred before me rooting the phone. If you could help me out that would be great! Thanks.

One, what firmware where you on? MDC, MDL, MF9? Two, what rom did you install??

Flash a different kernel. Or clean wipe. Problem solved.

Search for 'nag fix', as this was discussed at length when the phone was released and rooted.

[q] stuck in bootloop sprint ls980 please help!!!!

OK to start off i am not a noob at this, i have read though the forms and cant seem to find out why my phone will not come out of this bootloop. This started happening 2 days ago when I went to install a new rom on my phone. I powered down my phone, put it in recovery (Twrp), I wiped everything but internal storage. I then processed to flash the new rom. Everything went great. My phone rebooted and worked fine for the first 1 min, when i tried to pull down the notification bar the phone stuck off and went into a bootloop. I then tried to go back to my old rom and had the same problem (notification bar would not pull down). So i went to plan B and used the Back To Stock Form to restore the phone back to stock. The process went smooth as well not a problem at all. When the phone started up it allowed me to set up the voice navigation and name of the phone, as i went to update the prl and profile the phone shut off again, when it turned back on it starts normally and the goes to the lock screen where i am unable to make any iterations with the screen at all besides when it turns the blacklight off, as i try to use the knock on the LED light turns white but the screen will not turn back on (not even with the power button). Then it reboots to the lockscreen again and continues to do it until i manually force it off. I have tried everything from redownloading the firmware files, tried back to stock 3 times, hard factory reset, and reset in recovery mode. My phone is back to stock but i am unable to do anything with it unless i factory reset and go though the set up again, but even then i cant get a connection (even with wifi) without the phone shutting off and rebooting. Everytime the phone reboots the time reads 12:00am and switches to 12:01 really quick. I cant get a connection at ALL (I EVEN TRIED REMOVING THE SIMS AND AND PUT IT BACK IN AFTER BACK TO STOCK PROCESS.)
Im not sure if the application Dr.Web could possibly be making my phone do this. I did have it installed and did not remove before I tried to switch to the new rom. The anti-theft part was active.
SOMEONE PLEASE BE MY HERO AND HELP........I REALLY WOULD HATE TO DEAL WITH LG ON THIS ISSUE IF I CAN FIX IT MYSELF

god that is really hard to read...did you make a back up before you do installation? if so do a restore, if you dint, download another rom, kernel, put it in your phone, wipe everything except internal storage via TWRP then flash rom then kernel.

lol sorry i wanted to be as pacific as possible. I did make a backup before flashing the rom. when i tried to go back to it i had the same problem with it rebooting after a few mins. i tried flashing furnace 0.0.8 kernel after installing a fresh rom but same problem. I am back on factory recovery atm is there anyway to flash twrp back to the phone without it being rooted? i tried to get the computer to communicate with the phone when it turns on but it wont seem to connect unless im in download mode or recovery.

I had the same problem except with me, i was just trying to change fonts manually. It went into a bootloop and i stressed dover it for hours until finally i found out that you have to use the lg mobile support tool (you can find it in one of these threads on the lg g2) and revert it back to stock. That fixed it perfectly fine. Its a lengthy process but simple. If that doesn't work you have to do what the lg mobile support tool does semi-manually with another program lg flash tool which is longer but just as simple if you follow the directions given in the thread to the letter.

**** thats not good at all. This happen when I was using my S3, if IMEI is gone then you could not use the phone at all, theres no way you can get it back unless you made a back up. you have to sent it in man, sorry this is as good as hard brick.

My friend also has a lg g2 that i rooted for him would i be able to use a backup from his phone. Also when i turn the phone conpletely off and hold down all 3 bottons it brings me to a hardware key settings it does shows my imei number there. If i sent it into lg would they know the phone was once rooted or does the back to stock method cover it up? Thanks for your help btw

they have coders there, I'm sure if they really want to know they can figure it out. If you send it in to get it fix out of your own pockets (meaning you pay them) then i'm sure they dont care, but if you want a replacement due to warranty then it may be a different story.

I eneded up restoreing my phone back to stock and took it into my local sprint store it cost ne 75 dollars to replace the phone not under warranty (if u have sprint protection its free) i told them i took and ota update and it started rebooting itself. If you do get a replacement make sure u back up your efs files to a safe place on your phone. Theses files can become corrupted by flashing roms and kernals.

Not under warranty? Doesn't it have a 1 year manufacturer warranty? The G2 wasn't released on Sprint until November last year so it should have been covered.
Sent from my LG-LS980 using Tapatalk

Yes its still under manufacturer warranty but when i made a repair order with lg it said it would take 2 to 3 weeks to get my phone back and if they found out it was due to being rooted and flashing roms im sure lg would of charged a arm a leg to repair it. With sprint i got a new phone in 2 days or ordering it.

Phone randomly reboots and boot loops

Hey,
I am using the AllianceRom with safestrap, AllianceRom installed on stock rom slot. Recently, my phone would suddenly reboot while I am using it, making a call etc, then get stuck in a boot loop until I pulled out the battery, then sometimes it would start up well or get back in a loop.
What I have tried,
- Installing ROM to romslot1.
- Flashing stock verizon rom, phone worked normally for a while, I tried to get back to AllianceRom or RootDeOdex_NCG rom, but no reboots started again after like 2 happy hours.
Leaving phone alone for like 2 hours powered off, then when i turn it on, it works, for like a few hours, then bootloops...
Ideas?

Are you using WIFI? I had bootloops after updating to NI2 whenever I would connect to WIFI. Wiped caches didn't work, had to revert back to a backup ROM

Well yeah, I'd use WIFI after installing the rom to install my apps, and everything would go well, I'd even install apps and use the phone for a while. Then sudden boot loops.
Update: Just installed stock rom, and even re-partitioned using the

No I'm on stock ROM, just noting that I had the same problem and how I fixed it

So far:
only had one surprise reboot. Which I'm thinking is not so bad.
I am on stock verizon still, can't do a wireless hotspot. feel caged! Noticed I cannot send sms unless I use a third party SMS application, might be due to the fact that i'm not on verizon but I'm using Hello SMS (it rocks) so eff it.
- I rooted so I could get rid of the annoying "Sim card from unknown source" message, by uninstalling Setup Wizard. and restored some of my apps with Titanium.
Waiting till Sunday, if all goes well, I will install safestrap and it's back to customRom goodness...
Thanks guys for the help.

I337 extreme lag, random reboots, no recovery

Recently bought a new out-of-the box Galaxy S4 I337 from Amazon. Had i known how much trouble it would give me, i would have picked something else. When i first turned the device on, it was almost totally unusable due to lag and random reboots. Software version was 4.4.2. I used Odin to flash a rootable NB1 onto the device. Still had lag and random reboots. Upgraded to lollipop using this guide: https://forum.xda-developers.com/galaxy-s4-att/help/guide-att-samsung-galaxy-s4-sgh-i337-t3383078 and still have lag and random reboots. Also, the first time i upgraded to lollipop, i installed safestrap not knowing it wouldn't work on lollipop. Obviously, my recovery disappeared. When i figured out what was going on, i did a fresh install of lollipop. I got recovery back, but today when i tried to boot into recovery to wipe the cache, i discovered it had mysteriously stopped working again. If i attempt to boot into recovery, it just skips to the Samsung logo. I didn't install safestrap or any other custom recovery this time.
When i turn the phone on, either it hangs at the AT&T white splash logo and refuses to load at all, or advances to the lock screen. I have disabled animations and every widget i could on the lock screen and yet when i attempt to unlock the phone, it usually freezes. If i repeatedly swipe the phone for thirty seconds or so, it unlocks but it is still frozen and i have to continue swiping to prevent it from locking again. Eventually i'm able to navigate the phone normally, until it randomly reboots or freezes. Sometimes i see an error message that Touchwiz home, Process System, or SystemUI has stopped working or is not responding. This is always accompanied by a freeze. Also, choosing an option in the dialogue that comes up when i press the power button (shut down, reboot, etc) invariably causes the device to soft reboot. Other times a soft reboot happens totally at random, even if i'm not doing anything. Anybody have any idea what's going on or did Amazon just sell me a dud? All of these issues have been happening since before i rooted the device or upgraded it, except for the disappearing recovery mode.
Thanks in advance for your help.

Sounds like a data factory reset is in order. First you need recovery back so I would odin the latest firmware for the phone that can be flashed in odin. If it's still messing up then get Amazon to replace it.
Since you have safe strap though, try booting a TW based rom like Thor ROM or Golden eye ROM. That may fix some things.

Just wanted to bump this to thank you for your reply. Never got the phone to work but i was able to get it back to stock and return it. I got a refurbished S5 instead.

Freezing and rebooting

Classic "my phone keeps freezing and rebooting". I am quite in the know about flashing roms and such.
It started on the stock firmware 6.1.1 (i think it was). I dd factory resets, cache wipes the lot. It would still randomly reboot.
So i flashed Telstra version of 7.0. Still froze every now and then. Did the same things as above.
Flashed TWRP and wiped everything, flashed Renovate Rom and the bootloader for it, Still did it. Numerus factory resets and wipes of everything. It would freeze at any point from startup, to having setup the phone and making phone calls or on facebook or whatever. It would even freeze in twrp, or loading twrp.
I found that the data partition was corrupt so i re partitioned to ext4. Still nothing. I reformatted every partition so the phone was a complete brick with nothing on it and after flashing clean again it would still do it.
Whats the issue that I'm missing, or is there a way to log so i can find where it keeps getting stuck? It gets hot and blue light flashes and i have to hard reset it or sometimes i have to let the battery drain so i can turn it back on again.
pls help?

Hmm i will give you an advice so you dont have to wait for your battery to drain...just press volume down and power button for like 5 secs and phone will force boot. Anyway back to your problem...did you tried flashing latest stock samsung firmware?

This advice doesn't work with my phone even with holding the buttons for 30 secs and more. For rebooting I can only wait until the battery is completely drained. With little hope for another way shortening time to the next reboot any help is appreciated.

Same here...experiencing the same prob...

Same problem.

Sounds like you need your motherboard replaced i had the same issues on marshmallow thought the nougat update would fix it but realized it was a hardware fault not software..left it in store to get fixed and on repair sheet it said faulty motherboard..

As i know some S7 have motherboard hardware problem, mine has too, what help? warranty and they replaced motherboard. But if you root, you can say good bye to warranty, they look at knox first with this problem.
