wifi do not turn on

Strange things happen to my i9195... suddenly out of the blue,wifi won't turn on neither from quick settings panel nor the settings itself...
Everything else works as it should(data,bluetooth,airplane,gps,sound etc) but the wifi setting tries to turn on but immediately turns of. anyone had this problem?
and more important... a solution??????????

Which rom are you on? You could try reflashing a rom to clear any possible software issues

yes try reflash rom

thanks guys for your replies...
i was on stock rooted xxuamf4, i flashed both xxuamh3 and xxuamg8 (these two i had already downloaded) but problem remained. just to eliminate software issue , as a last resort i flashed CM 10.1.3 and magically my device was fully functional again( by the way ..:good: to CM...).
So WTF? i 'll try later to flash a stock non rooted fw and see what will happen...
p.s : anyone know how to change baseband? in my sgs3 mini i used to flash different modem for that. what works for this device?
p.s 2 : thanks again for your time guys!:good:

flashing back stock firmware , problem reappeared! it seems something has to do with knox , because every time i try to open wifi a toasted notification appears "prevention information... the device as detected...bla...bla...bla"
the thing is that if i root my phone and completely delete knox,knox agent,store and container agent, the notification stops but the wifi setting still cannot be enable.
any ideas????

Back to report that re-rooting with arco's method but with rootkit v2 (that includes kernel) seems to solve the issue! the steps i follow was :
1) gain root
2) install cwm recovery
3) with es explorer delete knox store,knox agent, container agent (both apk and odex files)
4) reboot to cwm recovery
5) clear cache and davlik cache
6) reboot and RESURRECTION!!!:good:

i think it's a kernel related issue. But first in order to eliminated hardware problem possibility, try to flash a cm rom. If your wifi and bluetooth works then you can be sure it's not a hardware failure. in my case flashing a different kernel solved the issue.
p.s : if you find a way to change baseband version ,please share the way!!!

you need flash same version Kernal file, example: when you finished flash MH2 stock firmware, if wifi shotdown, just flash MH2's Kernal file, file size around 7MB

the solution for me was more or less "flashing rooted arco's kernel" . but my model is 9195. i honestly don't know if there is one for 9192 ,but if i were you i would search for one!

I have problem whith my s4 mini.. I9192 dual sim
Baseband : Nd1
When i want to connectt to wifi i enter password.. As soon as i hit the connectt button wifi signal will desappear... I updated the frameware but no sucsess...
How to solve?
Is it hardware issue?

Same problem for me (1st post): new i9195 with latest XXUCNK1, never flashed before,
install twrp and make a backup, install CM-12.1 and CM-13 without any issue,
After restore to KK using my twrp backup I can't turn on wifi,
solution was to flash Modem_I9195XXUCNK1.tar from modem thread.
I notice that twrp doesn't restore previous modem I update to XXUCOL1

Wifi issue on AOSP Roms

Hi guys,
I have had the s2,s3,galaxy nexus,original note and i am used to flashing and modifying,but i have a serious issue with the note 2.
The problem is whenever i flash AOSP rom(cm,aokp,pa) my wifi would not connect.It shows the name of the network and when i click conenct nothing happens.Flashing back TW rom fixes it,wifi works like a charm. I've done full wipes but it doesn't seem to resolve the issue.I tried different kernels,but that doesn't help either.
So I am stuck at TW roms and i hate that.Anyone has any ideas?

You can try options 2 and 3 from this thread.

Thanks for your reply,but i tried this and it didn't solve my problem.

Anyone?

I Have the same problem...

Not sure that it will help you but I read something yesterday about this issue.
The solution was to NOT restore your Google profile during first boot so you should full wipe and try again.

This actually has nothing to do with the problem.
After a few days I finally found the cause ,and therefore,a decision to the problem.
It is the bootloader from 4.3 sammy leaks.It seems that this new leaks(probably the reason being KNOX) cause malfunction of wifi in aosp roms.What i did was ODIN flash stock MG1 from sammobile .This brought back stock recovery so i had to flash TWRP again and it solved the issue for me.
Before that i had tried changing roms,kernels,recovery,modems and nothing worked so I am pretty sure it is the new 4.3 leaks bootloader.
Some people will say that it can\t be the issue because they are using 4.3 sammy and do not experience the same problem on aosp roms,but i think thats because they flash it through CMW ,which doesn't change bootloader,while flashing through ODIN does.

With my Note2 this is not the solution. I've tried everything. What you said, move file "pit" ..... but nothing. I can not connect wifi. The connection does not appear region Spain, and have opted to choose europe, but neither. I do not know to do. CM 10.1 also does not work WIFI. In Stock ROM or Custom ROM works fine fine, but in ROM CM 10.1, 10.2, AOKP don't work.

I ran into this same problem and after many attempts at after market ROMs, C10.1 and 11, I had to go back to stock. Was never able to figure this out and it seems like not too many people ran into it.

Hey, I was able to get it working with the latest nightly CM build. The way I did it was to do a dirty flash on top of the LG stock Rom and then do a Data/Cache Reset. Now I'm not sure if it's been fixed in the CM build itself or if it was the dirty flash, but it's been running great so far.

I did not have the 0.0..... mac address problem in the latest CM11 nighlies but the wifi would not work.
After many reflashes I found that if in settings>wifi>advanced>region code I checked any country, the wifi would start working immediately.
Although the setting did not stick on reboot.

GPS not working on SlimKat 4.4.4

Hello,
So I've flashed before Slimbean, but had problems with the "can't connect to camera" problem, so I decided to flash Slimkat 4.4.4 which fixed the camera problem.
New problem now is that i can't get any gps signal. I can turn it on, but no signal. Anyone have a solution to this, or is experiencing the same problem?

Hi, the link you provided points to build 4. You can find build 9 which is the latest slimkat here http://www.slimroms.net/index.php/downloads/dlsearch/viewcategory/1183-d2lte
This is the one I have for my Koodo I747M. *note camera seemed a little buggy in some instances, so I installed open camera. Seemed to work a lot better.

I'll give it a try, thanks for the help. Quick question, will this work on my phone model without bricking? I only tried the at&t not the d2lte.
Also can you send me the link for this open camera you were talking about for my device as well?

I'd imagine it should be ok, since we have the same phone pretty much I'm on koodo which is pretty much telus without the customer service hehe. for kitkat at the end of development they basically lumped a d2att, d2tmo etc together. (this has reverted for the lollipop builds out there).
The last OTA I got was FOB1, so you may want to go to stock to ota to the latest updates from telus. Just so you have the latest bootloader/firmware. But that's up to you of course.
It's a google play app open source, the slimkat one I had seemed to lockup when switching from front to back camera and from camera to video. https://play.google.com/store/apps/details?id=net.sourceforge.opencamera&hl=en
What are you using to flash them?

I'm using TWRP

Ah, ok I just keep a backup in case anything goes bad flashing roms. If you use TWRP to flash them it only affects the boot image, data and system. So if you have problems you can restore from backup nice and easy.
I'm swapping between a few right now. So far my only uh oh experience was when I tried to upgrade TWRP, no problems with roms. But I use TWRP as well, works great.
Basically the baseband version on our phone, it's the radio and bootloader. Before I had rooted it I had gotten the latest updates by checking for updates. It downloaded and upgraded to FOB1 (Baseband I747MVLUFOB1), then I rooted and played with flashing. Not sure if you made a backup of your original install before trying another rom. But it's not a necessity for slimkat, I don't believe.

First thing to try for GPS problems is taking off the back cover and snugging up all the little screws around the phone. Sometimes they work their way loose and the GPS antenna seems to be the first thing to suffer from it.
If that doesn't cure it you might need to flash a stock or at least stock based ROM and rebuild the nvram. Here's a link that describes how to do that if you need to.

Nv Rebuild ... Custom. How to restore...

Hello this is my 1st post on this forum, i have a 7105 lte no operator and im from portugal. Ive tried cm rom and after that Dn4 rom, all works great except for gps. I was in the change i gess that afected my gps lock, i have read and the only thing i think that haven,t tried was the nv rebuild but, say a custom and won,t allow me to reset. I havs tried with stock rom, with dn4, with root and without same thing.... can anyone help me?.

Hi
XDA newbie, still learning where everything is! I posted this question in the general help thread but got no replies, then I found this section so please pardon the repost
I have a rooted Galaxy Note 2 N7105 (t0lte I think) running Samsung Stock software 4.4.2. I have previously installed various version of CyanogenMod and Ditto Note, and somewhere along the line have lost my GPS functionality! Running CWM recover, not sure what version off the top of my head. The exact issue is that when I turn GPS on, it shows the "searching" symbol endlessly and will not lock to any satellites.
I have tried reflashing the modem and every GPS fix app that I've seen suggested on forums, and it still will not lock my location by GPS. Power saving (wi-fi and mobile network) location still works.
From my research, I believe the NV Rebuild method (listed here http://forum.xda-developers.com/showthread.php?t=2211690) is what I need to do in order to fix the problem. However when I access the hidden dialer menu and select NV Rebuild it tells me "Not Support in Custom Binary!" Other people have had this issue and posted asking for help in the thread, but nobody replied or helped them.
As I mentioned, I am running stock Samsung software, not a custom ROM. The phone is rooted, and I do have a few Xposed modules installed. I also used Triangle Away and my bootloader shows the device status as Samsung Official. It also showed Official in settings when I tried to run the NV Rebuild. As far as the information went, this should be all I needed to make NV Rebuild work, but it still gave the custom binary error.
Does anyone have any suggestions for how to get around this? Do I need to completely unroot my phone and reflash a vanilla copy of Samsung 4.4.2 before it will work, or is there a workaround to make the service menu read my phone as official and run the NV Rebuild?
Any thoughts or ideas would be HUGELY appreciated as this issue has been driving me mental! (Please let me know if you need further information and I will try to provide it ASAP)
Thanks in advance!

Try lineageOS 14.1. My GPS was dead after going back to kitkat after lineage. NV rebuild also not support in custom binary. Found the solution here https://forum.xda-developers.com/ga...nt-n7105/rom-lineageos-n7105-t3538310/page136
From lineage I did only a format(not wipe or factory reset, I dont know what is the difference) in TWRP 3.2.3 and flashed zip of the omnirom kitkat, and GPS was working, then format and flashed official FTM ROM. Maybe not need to go via omnirom, for me it was clear that kitkat is not getting the fix and it was easier to flash a zip kitkat than an image from Odin.

Your solution gains my interest. I am using GT-N7105 too. The road of Roms I have been through is Lineage 14.1 -> Resurrection Remix 5.8.5 -> Stock 4.4.2
When I went back to the Stock rom, GPS totally unable to detect any satellite using any GPS tools app. IMEI blank but Baseband is still there, the weird thing is the phone network signal works without issue. :angel:
Have been trying many ways to fix GPS including reflash stock rom but still failed. I went back to resurrection remix 5.8.5 and GPS works without issue but IMEI is still blank.
Any recommended omni rom as you mentioned? and what is official FTM rom? A stock rom?
