[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?

WIFI Issue on 7.0

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.

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

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

MAC Address 02:00:00:00:00:00

After updated to Lineage 17.1 i am facing problems with Wifi. In Lineage 17.1 everything works fine (except wifi-calling and volte). When flashing back to Stock (via Oreo-RUU or TWRP Restore) i don't get any wifi-connection. If turning on wifi, system turns off immediately. In settings I found, that mac address is 02:00:00:00:00:00... searching this problem, i found out, that this problem happened often via update from android 5 -> 6. Flashing Stock ROMs didn't help, restore of prior LeeDroid Backup neither.
Did anybody face this problem in former times? Does anybody know where MAC is stored / what the problem may be?

I am experiencing the exact same issue. Same MAC address, same wifi issue. I tried flashing to stock Oreo, same issue. I'm going to try flashing stock Nougat, but I have doubts about that working. I also tried clean flashing the RR-P 7.0.2 ROM, and the same issue happens there too. I could not fin a way to restore the MAC address. I was able to look up the original address from my router's device log . . .
My HTC is the US T-Mobile version. @Golv can you help us with this new issue?
-UPDATE-
So far, going to stock Nougat INSTANTLY works. Right on the setup menus, all the wifi networks show up. Odd how stock Oreo gave us issues, but Nougat didn't. Will be going to RR-P 7.0.2 and seeing if the fix sticks I removed the SIM card when I put the phone back to Nouagt BTW if that affects anything.
-UPDATE 2-
Flashed stock Oreo after flashing Nougat, and in the setup menus, the wifi networks are showing up in STOCK OREO. Still with SIM removed. Now to flash the RR-P rom and see if I'm all set.
-FINAL UPDATE-
Flashed RR-P 7.0.2. Everything is back to normal.

Thank you very much! I checked whether the sim card has an effect, removed it and flashed Stock Oreo -> problem still exists. Then i flashed Nougat an experienced the same effect: Wifi worked right on the setup menu.
@Golv do you have any idea why this happens? I think, this problem should affect anybody, who wants to go back to prior versions.

I believe it is related to the hosd_signed.img file that likely writes over the persist partition. By downgrading, we are overwriting the hosd and the nougat ruu then formats and rewrites a new MAC address. It was interesting to see this happening, but I'm glad I found a workaround.

Sorry for the delay in reply. For some reason notifications stopped coming to me ...
Most likely you should change Mac address setting from random to device’s Mac address before switching to stock (Settings - Network - Wifi - Network details - Advanced - Privacy - USE DEVICE MAC).

When i use wifi no problem but with cellular it's difficult.
Can you help me to solve this problem?

Surely already done:
check the permissions of the affected apps
settings / management of applications / installed applications.
Uninstalled and reinstalled the affected applications.
If you have updated roms on roms, try a clean flash with the latest android 11 version.

Yes already done i think this is micro cuts on cellular reception for exemple when i use tethering with ftp soft on my comp i can't keep connection because the connection is unstable or micro cuts on cellular datas...
Have you an idea to solve this problem i am the only one facing this issue?

Did you install the rom in cleanflash?
For tethering try activate Usb debugging in developer option.
Special features /miui lab/AI preloading

the twrp work if you deactivate the protections on the lock screen or if you format the data.
here Twrp for android 12.

Okay if i understand correctly i can flash xiaomi.eu Android 12 rom using this twrp (this is already the one i have 1206) but before i must to disable the unlock pattern and finger print?
1) disable security pattern
2) flash the xiaomi.eu rom Android 12
3) enable security pattern
And do this every Time?
I read about some users loosing their twrp?

For the TWRP you flash it after installing the rom.
