WIFI Issue on 7.0 - Samsung Galaxy S7 Questions and Answers

PLEASE HELP ME!
I have 930F model. I was on ZPK4 (first 7.0 beta), and then updated to ZPKK (with ZPK4 bootloader and modem). My WIFI stopped finding networks, while SIM worked fine. When I downgrade to first beta or 6.0.1 everything works fine.
When ZPLH came out, I tried to update it again (flashing ZPLH bootloader and modem successfully). The same problem is happening again!!!! no WIFI networks found!
ANY SUGGESTIONS PLEASE?

hello

Wait for the official version

Still have the same problem after official DPLT was out! WIFI finds networks when i downgrade to 6.0.1 or when using AOSP roms.

I dont have this problem before or after root.
But this issue was reported when some people rooted the nougat with old supersu versions.
May be you can try this : backup ua data > wipe everything(except external storage - if ua using a memory card) in TWRP > flash the official firmware through ODIN.

I'm having the exact same problem.
If you live in Syria, Iran, Cuba or Austria then it's about the Wi-Fi region code. The only workaround is to enable airplane mode, turn on Wi-Fi then disable airplane mode.
Unfortunately, if you're having the same problem for Wi-Fi tethering, then you will lose the functionality of sharing internet connection.

You nailed it! I live in Syria and just found out that the problem lies in WPA_SUPPLICANT. Is there any way to fix this problem? I tried to replace the file from 6.0.1 or AOSP roms, but WIFI stopped completely from turning on.

I rooted nougat with SuperSU 2.79 SR2 and tried the method you suggested and did not work. Is there a way to have the WPA_Supplicant file for regions like Syria, Iran and Cuba?

I don't think that the file itself is responsible. Once "GB" region code is loaded, wifi works great. There's a new Nougat firmware released in the UAE, so fingers crossed.
Also, what AOSP ROM are you using? I tried Resurrection Remix and Wi-Fi still wasn't working.

I used all of them WIFI on RR works better than stock.. Do you have a link to the DQAS (XSG) update?

XSG Odin files have not been released yet. This is strange though, I've tried RR and wifi wasn't working. Makes me wonder if we actually have the same issue.

I think we have the same issue, but strange things happen! welcome to the Galaxy!

has anyone tried "MoKee" AOSP rom? It is the only one with working WIFI

Because it's the only ROM that didn't update the wifi drivers yet. I think any AOSP ROM that was built before 10/1 should have a working wifi.

Mokee is for china. Their latest build included new wifi drivers by fevax. I havent tried it yet. This is a report for TW xsg

[Q] Wifi not working on n8010 after upgrade to 4.4.2

Hi XDA,
Can anyone help?
I upgrade my Android 4.1.2 to 4.4.2 on n8010 using a firmware i find on the samsung updates website.
I flash it with mobile odin pro.
The firmware got installed correctly the only problem is my wifi button is not working.When trying to put it "on" state, it goes back to "off" state
Things that i already tried but failed to activate my wifi:
(Btw those are the solutions proposed on several websites)
1.Factory reset
2.Playing with the wifi button several time
3.Whack the n8010 at the back
4.Playing with wifi .conf file on my android using Total Commander
5.Turn it off for several minutes
6.Turning off everything including my router
I am considering of flashing a rom so that i get my wifi back.
But before i do that can someone help me find a solution to the wifi problem because i dont want to flash a rom??
But in case that the only option can anyone recommed me what roms is best to flash on n8010.
OR Maybe i should sell it since without wifi its useless.
Thanks in advance

You Can instan only by ODIN and PC.
You need the new bootloader in order to have a fully working 4.4.2 version by sammy, and mobile odin doesn't flash it, and like HUNited said you need to use the pc version of odin.

Hi, how do we get new bootloader and how do we replace it?
In my case bootloader is blocked on N8010ZCCMH1, this is china version and makes upgrade over pc odin impossible beside 4.1.2 and when I do the update to 4.4.2 over the mobile odin the WiFi is stuck.I have the exact same issue..
As far I understand, the bootloader is the key.But I was not be able to change it to any european version, any help regarding this issue will be highy helpful.
Thank you.

I'll give it a try.I see that lot of those who tried 4.4.2 are getting back on 4.1.2.
Is 4.4.2 really so bad?

Fingerprint scanner not working after initial xtrestolite root and flash

A few months back I flashed xtrestolite to my g920i and have since flashed odex, deodex and several aroma versions in different combinations. Since the initial flash the scanner has not worked. Currently using the latest unikernal, though was using a different one when I first flashed. TWRP latest too.
I was wondering if someone could give me some in site weather it's hardware coincidence or a driver not loading or something.
When I try *#0* and try the sensor test I see "unfortunately, hwmoduletest has stopped working"
Trying to utilise the scanner will always show "an error has occurred with the fingerprint sensor, if this message appears repeatedly please restart your device" though restarting has never worked.
I have not tried going back to stock as my carrier rom is 5.0.2 still.
Could someone please lend me some in site as to what might be causing this?
Thats because you're using 5.0 bootloader on 5.1 rom. You either have to wait until your carrier releases 5.1 so you can flash 5.1 bootllader or downgrade rom to 5.0.
Where you ever able to fix this problem? I am having the same problem! Thanks

This is a problem associated with not updating bootloader. When you update to 5.1.1, you have to update your model specific bootloader to 5.1.1.

Mobile Data not working for some apps in latest Nougat Builds.

Hello everyone,
Like the title says mobile data is not working for some applications in latest nougat builds , changing different roms does not work either. crDroid, Tugapower, Resurruction Remix, all apps are working perfectly on wifi data, but as soon you switch from wifi to mobile data some apps like for example Facebook app will not use mobile data. And as soon as you switch from mobile data to wifi, applications will work normally. As mentioned above this happened with almost all latest nougat ROMs which i have tried. So I tried MM based Oxygen Os port from OneplusX and applications worked just fine with that ROM. So anybody faced same issue with Nougat based ROM and found any workaround for the same? I cannot search forums for the same as i have very busy work schedule, so please kindly point me in the required direction whoever have solution to this.
THNX in advance.

Workaround: reboot ?
Hello,
My oneplus One has Sultan's ROM, latest version for branch Android 6.
I have the same problems that's around a week, since I flashed.
Symptoms are : mobile data is working, but if switch it off for a long time, when I switch it back it's not turning on, I have to reboot to make it work again.
The wifi doesn't have the same problem, I can switch off and on.
So maybe it's a CM/LineageOS bug ?
-----
ok it's working again now. I'm htinking about a mobile data provider problem ...

like i said it works for some apps and not working for other apps, and it is not ISP's problem, problem is related to all the ROM I guess.

Stock Nougat Firmware "BLUETOOTH WON'T TURN ON" (HELP)

suddenly i bought this phone second hand. then when I tested Turning on my bluetooth it won't turn on.
Is there anyone experiencing the same problem?
I already did troubleshoot and performed this steps:
1. Wipe cache of Bluetooth Applications on System apps in settings
2. Force stop Bluetooth Applications on System apps in settings
3. Restart my phone
4. Wipe Cache on stock Recovery & restart my phone
5. Restore Factory Settings on Recovery
but suddenly bluetooth still won't open when touching it on notification panel nothing happens even directly on the settings toggling the bluetooth won't work. :crying:
my phone is untouch on rooting world.
So my questions is;
1. Will rooting and flashing rom can solve my bluetooth problem?
2. Is this a hardware problem?
3. Is there a separate chip or module for bluetooth on the motherboard of S7 edge?
to all XDA members I'm asking if you have an idea on this matter please feel free to reply to this post.
thanks you so much!
Rooting and flashing a ROM shouldn't be necessary, if you're willing to lose data I would just recommend a full flash via Odin as it keeps you on stock firmware, doesn't trip knox etc. There's stock firmware files and a guide on www.updato.com
Sometimes the OTA updates can be buggy and end up with issues like these. It could be a hardware problem, but I suspect it's probably more likely to just be something wrong with the firmware or bootloader.

I tried flashing newest stock nougat firnware XTC csc.
Tried it using ODIN
But still bluetooth won't turn on.
Can you say that our problem is hardware failure? But I think if it's a hardware issue then wifi should not work too. Because wifi and bluetooth is on the same chip module. ???
Update: I've talk to numerous technician and they think its not a hardware issue since my wifi is working. They said that wifi and bluetooth is on the same micro chip module. So if it is hardware issue on the bluetooth wifi should not work too. ???????? @dhawal4u
Same Problem here. Since 2 months after trying Badman Rom my Bluetooth doenst work. Now I load Stock Rom, Bootloader, Modem but no solve for the Problem
