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!

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

"cyanogenmod account has stopped" after flashing ZVC stock rooted ROM

Hi,
Yesterday I posted about why my Wifi and 3G didn't work after flashing CM11. With the help of of engine95 I got this to work (thanks!) but now I am running into another problem:
The GPS doesn't work. As far as I can tell the standard solution is to flash stock again and get a GPS fix, then go to back to CM. So I flashed ZVC_Stock_Root.zip again. This worked yesterday, but today it shows a message "cyanogenmod account has stopped" and reboots after a while. I have done a factory reset and wiped Dalvik cache but the message still appears.
Does anybody know how to fix this?

Delete system in recovery and re-flash ZVC stock zip to get rid of pop up message.

This ^^^^^^.
Also. when you flash to the stock ZVC, make sure everything is working and make a backup in TWRP/CWM. That way you can bounce back and forth when CM/AOSP Rom's have issue's that need to be fixed with stock. ie update profile prl, GPS.

Thanks a lot, everybody. Formatting system allowed me to boot up stock and get a GPS fix. I have backed up stock and can switch easily between CM and stock now.
It took a while but now I have a fully functioning Optimus G with CM11.

[Q] Battery drainage because of mobile data

Hi Guys,
I am new to this forum and got a small question. My girlfriend has an Oppo Find 7a. You guys probably know that the stock ROM is ColorOS. In my opinion it's crappy as hell, lots of bugs and issues, so I decided to flash Dirty Unicorns 5.02 on it. I did that yesterday and all is working fine so far, except that the battery drained from 100% to 64% last night (in 8 hours). See the photos attached. According to the photos it seems clear that the issue is the mobile data usage. I've checked the settings and it seems mobile data loses connection, connects again and loses connection everytime. Probably this is the cause of the battery drainage. Somewhere on this forum I read something about flashing Alucard 1.1a kernel on it to fix this issue. I want to try this in the evening, but does anyone know the correct type of this kernel as I found different alucard 1.1a download links?

Can someone please help me out with this? Yesterday evening I just flashed the Alucard 1.1a kernel via the custom recovery. I also removed dalvik/cache and rebooted after that. The Oppo boot logo appeared, but it stayed like this for 20 minutes. I'm not sure if I have to wait any longer to make it work or if the phone is just not booting up anymore with this kernel. Any advice?

before flashing DU did you flash proper modem and trustzone firmware?

Nope, actually I didn't. I wasn't aware of the fact that this was necessary. I had ColorOS 2.0.0i on it and flashed DU directly on it.
Can you maybe tell me what the proper modem and trustzone firmware is? And can these still be installed now even if DU is already flashed on it?

well you can do a clean flash again but this time you have to follow this for how and why to flash modem and TZ firmware:

So, one more thing If I may ask. What is the best thing to do from here on:
1. Flash modem, flash firmware, flash DU (directly over the DU rom that is installed now without doing a factory reset / wipe)
2. Flash modem, flash firmware, perform a factory reset / full wipe and then flash DU.
And will the newly flashed modem and firmware stay on the phone when i do a full wipe?

do a clean wipe, then flash modem, then firmware (in bootloader) and then rom along with gapps.

It's been a few weeks, but I finally had the time to do this. I've done a full wipe in TWRP and then flashed the modem on it. This showed succesful. It took about 10 minutes before the phone booted up afterwards. After that all seemed fine, so i've put the phone in bootloader via a command in cmd and installed the firmware. This also went succesful, but now I still have the same issues on the Oppo regarding the provider issue as mentioned earlier. The data connection is still being lost very often and it still seems to be draining battery (although less than before). Is there something else I can do to fix this ?

If you have recently done a clean install, give it some time to settle down. For Data connection issue, make sure to check your APN and also try a different sim or this sim in some other phone, could be signal reception issue.

I will give the battery thing some time to settle down then. About the data connection issue; This was not an issue on coloros, but I will check apn and try another sim. Thanks again!

I've changed the APN settings, as they stood on some kind of roaming setting. It's now been set to live.vodafone and seems to be functioning better already . If I still run into some issues I'll let it know. Thanks for helping me out

[Q] Can't turn wifi on. Tried with 5.1 and 4.4.4

I should mention that this phone is not mine and it was brought to me to fix. It could not get past the samsung bootup animation screen.
So I installed TWRP 2.8.6.0 and wiped everything. Then the first rom I flashed was [ROM][5.1.1][AOSPA] ParanoidAndroid 5.1 (5/21/2015) Then flashed gapps 5-22-15 from euroskank/banks. I wiped dalvik & cache (Is this necessary?) and rebooted.
The intro screen did not let me skip the wifi connecting part (I thought it was a bug in that version) and it told me to turn on wi-fi to connect.
So I tried the same thing with the version before that and it let me skip. After that I managed to turn it on once? But it the phone crashed and soft rebooted.
I tried other 5.1 roms and the wifi doesn't work still. It doesn't let me turn it on. Same with 4.4.4 with cm11. Also, the Wi-Fi MAC address says unavailable. Don't think that's supposed to happen?
Does anyone have a fix?
Edit: I took out the SIM card to see if that did anything. Then all of a sudden the grayed out On button turned blue and wifi networks appeared... But I couldn't do anything else since it made me restart. It stopped working after a reboot :/ Tried it several more times and couldn't get it to do the same thing..

Hope you had read the posts, it should had said the Rom is not "stable"
If your friend are going use their phone for daily driver, then I recommend you not have the 5.1 Roms for now because it's not really suitable for that right now.....
I'm not sure the CM11 you have flashed is unoffical or is offical. Offical onces are still work in progress and have most of the things broke (I think)
Here is a Kitkat Rom for SGH-T989
If your friend really wanted to have a Lollipop running on his/her phone, then I will recommend this one. Make sure you read the instruction CAREFULLY if you do wanted to install this one since it's a bit complicated with it's "virtual partition"
Or, if you wanted it to be just stock. Odin it back to normal, here is a instruction (with video too).
This is all the possible way to fix your friend's phone that I can think of, if you have encounter any error or have anymore question, feel free to reply :fingers-crossed::good::highfive:
P.S: yes, wiping dalvik & cache is a way to prevent any error caused by another old Rom if you decided to flash a new one. It's a good way to prevent error during Rom flash process

Thanks! I'll try the 4.4.4 rom you sent me. I'll post an update when I get to it.
Uh and about the 5.1 you linked. For the virtual repartition part in his post, I couldn't open the phone's internal storage on the computer after formatting it to ext4. So I'm confused about that step.

For the virtual partition, it's best for you to have it on the External SD card. Since TWRP transporting file to Internal Storage after that seems bugged (not working)

XT1789-04 Restore Baseband

I am trying to revive my old z2 force t-mo edition. It basically crashed after an OTA and lost baseband and IMEI and i threw in in a drawer for months.
I tried flashing newest firmware-nothing, i tried unlocking bootloader and flashing second new firmware-nothing. The device does turn on--just no data, no wifi etc. I'm not too familiar with blankflashing, is this something i can even do with a device that turns on? Will that even work? Moto assistant says they are "unable to verify a match" when i pick repair device and select XT1789-04. Does anyone else have anything else to try? I have not rooted, have not installed pie firmware or anything. Long story short, im now in need of a working phone so i just want to get this working again!

Same boat as you! Have tried everything on here. What's a blank flash?

Have u tried this?https://forum.xda-developers.com/z2...m-tmo-z2-force-27-1-5-flashall-march-t3917070
I was in your situation and this fixed everything (in my case 27.1.5 didn't work, 27.1.7 worked)
Just remember to do a factory reset in stock recovery, after flashing. Without it, I had bootlops
