Bluetooth disabled?? Please help

So I just rooted my Samsung sgh t-989 the tmobile one. I put TWRP 2.5 and have Cygenmod 10.1 running. I was all excited because I have notdone this kind of stuff since middle school.
But The problem is my Bluetooth is "disabled" When i try to turn it on it just goes right off, I have no idea where to start to fix this problem. I already tried google and searching the forums but no solutions.

Which date of cm10.1 did you flash? You need to give more details. Flash a custom kernel? What's your radio you're using?

I've had exactly the same problem, using the CM 10.1 RC5a.
Bluetooth will do as you described - be disabled, when clicked on, will jump to off again.
Restarting always fixes it momentarily.
If BT is on, and successfully connects to my car, and I'm able to place a call, first no one can hear me, the call is dropped, and BT shuts off to remain permanently disabled til I reboot the system.
After a reboot, its usually ok for a couple hours.
Lots of other users are having the same problem....

Also, flashing this fix now, will report back:
http://forum.xda-developers.com/showthread.php?t=2174100
I wiped dalvik/cache, flashed the BT fix, fix permissions, then rebooted.
Just CM 10.1 RC5a, UVMC6 radio, I upgraded firmware using the UVMC6.aio.tar.md5 file made by Mikeyman
Hope it works - really tired of having to reboot every time i want to make a call over BT car audio...

36 hours on this and no BT crashes!
Faster connection to car audio, and call stability is much better.
Also remember after reboot to delete all devices, and re-add them.

[Q] no wifi or blue tooth and I've tried almost everything.

Well I started off with the jedix roms and wifi and blue tooth were working fine. updated to jedix19 or 20 and wifi and bluetooth were spotty, sometimes they would turn on sometimes after turning on it would turn off or just lose BT connection.Went to skynote rom and same thing. went to mean bean same. also same when going to ezkat. I just updated my bootloader to the mk6 without knox stuff and tried flashing the wifi fixes with odin but still no wifi or BT. Is there someway of getting wif and BT back? Thanks for the help in advance.
Edit: oh yeah using an att i317

I have the same problem, I already did a thread, I hope that someone could help us

Did you ever find out?

Maybe a lil more info will help.. Yeah I read everything you tried to flash.. And nothing working.
You can try flashing AGNi kernel for working Wi-Fi. You can find it HERE»»»

Anything with 4.0.0 is for kitkat.
Anything 3.9.7 is for 4.3 fyi.
Since you tried the rest it's time you tested the best lol. It's still beta but very stable btw. Go here»» http://goo.gl/hnP1sV

And if I'm not mistaken....both DN3 and eZKAT require the same fix for wifi....
Agni kernel flash is the preferred method...g

this is an old thread...but fwiw the only solution for me was to flash the complete stock att ma4 4.1.2 rom ...and then work back up to whichever rom of choice.
this was after trying multiple bootloaders, kernels, modems, recoveries, roms...4.3, 4.4, etc.etc...
i did find another flashing combo that seemed to fix things but after a period of time wifi/bluetooth would randomly disappear again(!) and i'd have to repeat the whole process over again. strange.

I had tried going back to 4.1.2 rom & went all the way up and it still didn't fix the wifi/bluetooth problem.

What boot loader are you on?

[Q] ParanoidAndroid 4.4 - Wifi wont start

Hey Guys,
i installed ParanoidAndroid 4.4 on my i8150 ~2 months ago and everything worked fine so far. But yesterday the Wifi stopped working. When i activate Wifi in the settings, the button gets grey and nothing happens.
I tried a hardreset, wiped Cache and Data and flashed the actual version of the rom but nothing worked. Wifi is still grey and i cant activate it.
Does anyone have an idea how to fix this problem?

[Q] Galaxy S4 lost messaging/calling but internet works. Anyone else have this issue?

This has randomly happened three times to me so far on different roms. I searched Google and XDA forums and maybe i am searching for the wrong terms so i will ask here.
I had Hyperdrive installed on my phone for 3 weeks with no problem, i was texting last night no problem. In the morning i woke up and could not send/recieve messages or calls but i could surf the web, check facebook, and everything. This was on and off of wifi. Reboot several times, Full wipe and restored to a previous nandroid, same problem. Another full wipe and reinstalled hyperdrive from scratch, same problem. Finally spoke with Tmobile, no help. Grabbed Carbon rom and then everything worked fine! Why?! Does anyone know why that happens? Same thing happend with the 4.4 Google edition rom. Worked for days then no network. Went back to carbon and it worked fine.
TLDR:Hyperdrive worked great for a week then lost all mobile except internet. Full wipe several times and problem persisted. Changed to Carbon Rom and it worked fine
Used Google Edition 4.4 for days and then it also lost all mobile except internet. Full wipe several times and problem persisted. Changed to Carbon Rom and it worked fine.

What is your modem?

Baseband version shows
M919UVUAMDL

Update it

You can grab the new nh7 modem from Shinyside in development, I ran with my MDL rom no problem.
Pp.

I updated to the NB4 and it seems to be working again. Ill see in a few days if the problem comes back. Its weird that it works great and then out of nowhere it acts up. Thank you for your help!
I will try the nh7 modem from Shinyside if i have the problems again. Or i will just stick with Carbon Rom, it works great but i wanted to try something different.

Nh7 modem has improved my signal all around, I noticed it on my previous rom and going to nh7 stock rom has been a good move for now.
Pp.

So it happened again with the updated modem. After 2 weeks of using Hyperdrive i lost service again. Reboot, wiped and used a backup. Still no service. Wiped and re-installed from scratch, still no service. Updated to the newer version of Hyperdrive, still no service. Wiped and reloaded Carbon and i have service again. I do not get it.

You might have to update your bootloader

Ditto, for Serio, that has been a common issue between KK roms and latest KK firmware.
Go for the nh7 bootloader , don't stress knox.

[HELP] [SOLVED] Weird Wifi issue

Hey guys!
My wifi has been behaving strangely: when I get connect to a network it connects and disconnects intermittently( within 2-5 minutes usually). The weirder thing is, the only thing that seems to fix it for around a day or two is wiping the dalvik cache.
It is really annoying that I have to wipe the dalvik cache every other day to have a functioning Wifi! Please help :fingers-crossed:
P.s.:
Sleep policy is set to never;
I have tried new ROMs,kernels and modem - same problem.
I own a D855, international model, currently running Cloudy G3 2.5
UPDATE: Hey the problem seems to be fixed now!
I deleted the file in data/misc/dhcp and rebooted the phone a there it is! I have working wifi for 4 days now!! Thanks everyone!

Try to clear your cache. If this doesn't work reflash your stock rom or rom your using this will help. It also could be an issue on your router. I once returned a router because it kept disconnecting the wifi with my phone and laptop

I cleaned all cache again and flashed Fulmics ROM. So far I have a stable connection, I hope it lasts
