look in settings>wireless & networks> more> tethering & portable hotspot. this is where you can toggle it. or if you want an app back on your home screen try a long press on home screen>shortcuts>activities>settings>tethering and portable hotspot. and viola you have it back

I've tried everything and nothing, apparently that is blocked, it will be because I used to gsm unlock method.

try reflashing stock rom unrooted and it should come back. it may have to do with the gsm unlock you did but reverting to stock and then rerooting should fix it for ya.

@Andr3s - you did allow the sprint updates to run after you rooted (or installed the current ROM), right?
If the sprint updates don't run, the hotspot won't show up.

Hi, I had the finished version in AMF9, I did downgrade the modem to MDC to unlock and work in GSM mode, then went back to update the modem to AMF9, I root the phone and the next day the phone using the option disappeared and I have the latest version of Sprint.

You wrote AMF9 twice, so I assume that is not a typo. The latest Sprint update is MF9 - you are on MF9, right?
Did you install the hotspot mod? If so, when? were you on MDC modem? or MF9 modem? (which mod did you flash?)

Hello This was what I did
1 - updating my phone to version MF9.
2 - Flash MDC Modem version
3 - Run the unlock to work on GSM
4 - I returned back to making flash MF9
5 - I did the root of MF9
6 - Install all my apps and when I looked at the option of the option links Hotspot disappeared, and when I install any of these tethering app says "Hotspot not Supported". but the strange thing is that before if it worked.
Also install the Hotspot Modem, both odexed and deodexed dome and nothing.

You indicated that it worked before - do you mean - before step 1 in your list?
Here's my understanding of how this should happen. When you wiped your phone, and installed the new ROM/modem/etc, the phone should do a handsfree activation with Sprint when you first boot up. If this activation is skipped, the hotspot (and the sprint bloatware) doesn't get installed.
Sorry if I'm being confusing - hope this helps.

A it should have been that, I do not turn the phone on Sprint, since I'm outside the United States, that hurts.
thanks

WiFi passwords forgotten after reboot

I don't know if this topic has already been covered. I didn't see it in a wick scan of the forum.
My S5 won't remember Wi-Fi passwords after I reboot. As long as I don't reboot, I can go from location to location and it automatically connects to wireless networks that I've connected to. But if I reboot, it makes me enter the password again.
Has anyone else had this issue? If so, us there a known fix?
I am rooted. I have tried forgetting networks and commenting to them again. As soon as I reboot, it's like I never connected to any networks. I have to reenter all wireless passwords.

I had the wifi password issue and battry life sucked. I cleared cache partition, the reflashed the ni2 firmware from here
http://forum.xda-developers.com/showthread.php?t=2842069
and now my phone "issues" are gone.
And my phone is back to lasting over a day.

I think you didn't flash the new Modem that go with your ROM

Explain?

I followed the destructions to the letter

Yeah this happened to me make sure that the rom you are flashing matches the firmware u are on. ie if u are on ni2 make sure u don't flash an nc2 rom vice versa.

SM-T330NU Wifi detection and disconnect issues

Hey, so like the tItle says having issues with Wifi detect and staying connected
My Device is SM-T330NU
rooted with
SM-T330NU-LP-5.1.1-PERMISSIVE-ROOTABLE-IRBLASTER.zip (@moonbutt74)

Can't switch on WiFi

Hi guys!
I had problems with my wifi and I found a solution online saying that I should delete these three folders:
/data/misc/wifi
/data/misc/dhcp
/etc/wifi
I done that and now the phone's WiFi cannot be switched on anymore (WiFi switch stays gray and cannot be turned on).
Is there anything I can do other than a factory reset or flashing phone?
Can anyone zip up those 3 folders and post them here?
Thanks !
Phone info:
Model: Note 4 N910C
Android version: 5.1.1
Phone is rooted.

Can someone please post these folders?

Do you have any custom recovery (CWM,TWRP,etc) ?
Don`t you have any backup (Nandroid) ?
If so , then restore the back up through the recovery.
If , not , then I think you`ve to flash stock firmware through Odin (at your own risk).

I have the same problem but i didnt deleted any folder. Just stopped working and i cant switch on wifi. Weird is that today when i was browsing google play from 4g data plan the window with wireless networks appeared and i was able to connect a wireless network. After 10 second was off again and the switch button is grey again. I am on stock 6.0.1 and not rooted. I think is a hardware problem probably the wifi+bt chip has some unsoldered pad to motherboard.

I don't think it is hardware problem. Restart and fully charge your phone and try to turn on wifi. Maybe you have some application (battery saver and similar) that prevent you to turn on wifi.

I'd take it into a Samsung Service Center and let them have a look at it. As there is obviously nothing you can do to repair the problem yourself.

I will try to repair it tonight by myself because i dont have guarantee anymore. I will post here the result maybe we can repair this error.
i tried last night . I heated the wifi chip until i was able to move it slowly and the let it cool. Surprise after reasembly wifi was working ok all night and today at work i saw the same problem .
I think we must change the wifi chip but i cannot find it to buy... Any help ? Anyone knows an app or something similar to see if the chip is detected by motherboard? I think it must be detected if the mac adress of the wifi board is displayed...

Mobile Data not working after nougat update

Hi i am having a weird issue with my sprint S7. My mobile data is not working after the nougat update. the weird thing is the LTE icon is showing on top. And if i make a Wi-Fi hotspot the device connected to my hotspot does get internet access... if anyone can help or guide me, i will be grateful. thanks
P.S. i have checked APN settings, restarted and gone to air mode and back.

This reply isn't a help but ive had quite same issue but it's my wifi! It keeps disconnecting and reconnecting after the update. UGHHH and i hate the new font.

Had the same issue, update profile, update prl, perform hands free activation and restart the phone. Worked immediately after reboot.

can you link the theards with tutorial how to do this?

Same thing happened for me. I just rebooted my device and it fixed itself.

Data was working for me, but i couldn't send or receive mms. Mine was just a issue of making the domestic data available on the settings.

Don't know where tutorial is, just go to settings system updates and you'll see the profile and prl update options. Then go back to main settings and click active this device. Then reboot.

I tried everyones advise and my phone still isn't connecting to data.

Flash the latest firmware using odin. That should fix it.
