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

No baseband- no IMEI not sure of anything at this point

I started with a fresh non altered I747m. The first thing I had to do was carrier unlock (PetroCAN sim) and then rooted the phone.
I pretty sure i did a cfroot and installed the newest pacman rom and all worked- just no internet ( the phone and texting worked) so I played with the APN for a while then decided to try a couple of MODEM zips (Rogers and AT&T) and flashed those in CWM.
Downhill fro there- No more SIM, no baseband- no IMEI no APN- could not even create an APN.
Tried diferent 511 ROMS (DU).
so then I did the even more stupid thing and retored the original NANDroid backup and now it is really bad- stuck on the samsung logo.
I did write down the IEMI number and I did check the baseband version (i did the check in like a dos screen on the phone) I747mluf0b1
What should I do now>?? i would be happy to return it all back to stock I really screwed this phone up bad
note: I did do a full nandroid backup before updated to 511 but i saw that there was no EFS folder (an this was when everything was working correctly)
So i think i the phone is toast..

Are you running the latest modem and bootloader?
I suggest you use Odin to flash the latest stock rom for your phone from sammobile.com to see of them either comes back.

I downloaded the correct i747m bell stock version that matches the buildprop I747MVLUFOB1
It is now in a softloop 'SAMSUNG' and sits.
it just came back up

Did you get the phone working?

That got it!!! YEAH!! I been working on this phone for days. All of a sudden the STOCK ROM is the best rom ever!!! hehe

If you have to restore to stock in the future, it is best to uncheck auto reboot in Odin. When you see the word reset in the status window, remove the usb cable, remove battery, replace batter, boot into stock recovery, and perform a full wipe. This helps to prevent the boot loop.

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?

undetected sim, Unknown baseband, Rogers, d2can, cm14.1

I recently installed cm14.1 on a Rogers d2can phone and I got unknown baseband and sim card stopped working. I tried flashing different modems which made the situation worse as now even old cm11 roms show unknown baseband.
Can someone please tell me where I can download modem zip file that works for Rogers and for cm14.1?

I recommend flashing the latest KK stock ROM from sammobile.com which will restore your phone back to stock and ensure the bootloader and modem/baseband are matched. After flashing stock and confirming that the imei is correct, then flash twrp, cm14.1, and gapps.

I was downloading from sammobile.com very slow and the download was interrupted in the middle. I will try again later.
Is there a better site to download firmware from?

So I downloaded it and flashed using odin. Flashing took a while but it passed. The phone got stuck on bootloop though.
So I booted to stock recovery and performed a factory reset. Booted again. Now it works!
I'm going to stay on Touchwiz 4.4.2 for a while.

Glad you got it working.

I would not call "staying on Touchwiz 4.4.2", "working" more like opening yourself to a long list of known exploits.
Others are having the same issue (cyanogenmod is dead so I removed the link, hope LineageOS fixes the issue some day.)
Using the last good CM-13 build is probably the best for now.

sim not provision ed MM#2...... easiest fix ....please n thanks;;;;

We'll need more information in order to help solve the sim problem like model #, ROM, etc.

Empty IMEI

Hi
Hoping someone here might be able to help as somehow I’ve messed up my IMEI.
I flashed alexndr stock rom over my stock rom with the force XEU option enabled as my default CSC is H3G. Everything worked fine but was failing safety net so decided to flash back to my stock rom with odin but now my IMEI is empty.
I have the EFS backup that Alexandra rom installer created but flashing this doesn’t seem to solve the problem and what’s strange is if I flash alexndr rom back onto my phone my IMEI comes back and everything works normally but with the stock rom its blank.
Anyone know how to fix it?
Thanks

I managed to solve it was definitely a baseband issue. It looks like when I flashed the alexandr rom it updated the baseband to DTD7 where as my my carrier firmware I was trying to flash back to was still DTC5.
I've flashed DTD7 firmware now and everything's back to working normally.
