[PROBLEM] BT won't turn on - Motorola Atrix HD

As described in title bluetooth won't turn on. Stock rooted JB 4.1.1 It says BT turning on, but it goes to off by itself
I have flashed the stock rooted ATT zip through SafeStrap in a different slot and BT works alright
Any suggestions?

Wifi working? Usually they go out the same time.

WiFi working fine. Just BT. It's a major annoyance cause I relay on my BT headset too much to get work done.

I have a stock HD that is having similar problems. The BT will turn on but randomly disconnects and turns off/on randomly. This is my second HD (cracked the first one) and the first one worked great. when I connect to my car I usually can't even complete a 1-2 minute call without BT turning off.

[Q]/[HELP] Xperia Z-SBH20 connection issue

Hello!
I bought an SBH20, paired with my XZ via NFC, listened to music, then disconnected the headset, using the NFC.
After a while, i tred to connect again via NFC but all i get is a 'connecting' message, BT turning on -white BT icon- but no real connection, therefore the BT turns off.
After several tries it finally connects, but it's not reliable this way.
I noticed, if i enter to settings(not turning anytihng on/off) and trying to connect (still using NFC), everything works fine: connects, disconnects perfectly, and handles the BT as it should.
I've reseted the headset, tried single and multi point modes aswell. Deleted the BT devices, then repaired, still got the problem.
Am i doing sth wrong? I want to connect and disconnect the headset with a simple touch, and not toggling the BT manually (NFC yeah...) Is this something, SBH20 is not compatible with?
(btw sony support says: "For subsequent connections between devices that have already been paired once, make sure that Bluetooth™ is turned on so that the devices can connect automatically." If it's a "must" , then what is the [email protected] use of the NFC??? Just to pair once???)
Please share your experiences! Any advice would be greatly appreciated!
Thanks for reading ( and sorry for my english)
I actually have the same problem using the SBH50. For me sometimes it connects perfectly fine, other times it doesn't and I have to go into bluetooth settings after which it seems to connect properly.
I have noticed that it also depends on how I disconnect it; if I remember to touch the headset to disconnect then next time when I try to connect I have more chance of it being successful. Also, when I try to connect I hold the headset aganist the phone even after the ‘connecting’ popup until I get the 'connected' popup.
These are just work-arounds which aren’t always 100% successful though so would be good to find out what the proper method is.

It is a real shame... In my case it's the opposite, if i touch the headset to disconnect, the next nfc-connect tends to be less successful.
(and i noticed that it also matters if i turn off the headset after disconnected, or not)
And what is really odd, that i don't have to do anything in the settings menu ( or bluetooth settings) just open it, and everything works like a charm...( all connect or disconnect tries are succesfull, no exception, even if i push the headset repeatedly to the pohone's back)
I'm not affraid to mod some system files, apps, maybe build.prop tweaks, but i don't know where to start. In bulild.prop there are only a few nfc related lines (tried to enable/disble those)
So i'm not alone...maybe even more people are in the same boat, trying to solve this.
Again; any related info is welcome
I also have a sbh50 but i normally disconnect by turning off the headset. I have set it in smartconnect to turn off bluetooth automatically when the connection shuts off but it doesnt always do that.
It reconnects with no issues when bluetooth is on and i turn the headset on again. I use the nfc tap only for the initial pairing.
The only issues I have is the google music skipping issue that i posted the other day and the gmail smart connect not working on the sbh50

Well, then we don't have the same issue. I tought i could use the nfc for connect/disconnect (i actually still think it is capable of that, just sony messed up sth)
Could you try to connect/disconnect and connect again with your devices, please :angel:
I'm really curious about this whole nfc story ( why does the headset have the chip/tag if it only works for initial pairing -its not a big deal to pair manually, especially that it has to be done just once-, and on the other hand: if i put nfc in the device, why not put in this functoin too- not a big deal: a proper working BT toggle, but it brings a tad more functionality-

Bluetooth won't reconnect automatically

I am rooted but still using the stock ROM. I have two Bluetooth-enabled Pioneer head units and a Bluetooth adapter for my home stereo system with this issue, so I know it's not the other Bluetooth device that's the problem.
When I pair the other Bluetooth device, everything works fine until the Bluetooth device disconnects. I either leave the area with my One, or turn the car off. When I come back home or turn the car on, the One will not reconnect unless I manually turn Bluetooth off and turn it back on again. I don't have to redo the pairing, just cycle Bluetooth off and on. This gets really, really annoying with the car stereos because I have to do it every time I make a stop.
The weird thing is, I had the problem before and it went away when the KitKat update was released. Unfortunately it only worked for a few weeks because I sent my One in for the pink camera issue. I did a hard reset before sending it off and rooted it got back, and now the Bluetooth problem has returned even though it's still on 4.4.2.
Anyone know how to make this go away?
No one is having a similar problem or knows how to fix this?

Problem with wifi and bluetooth when they are both turned on

Hi
I'm experiencing an odd problem with my phone. I'm on Skydragon rom (android 4.4.4) and I'm experiencing the following problem (quoted from another site with the same issue):
I have wifi on all the time and working properly, no network drops. I connect my bluetooth headset. Wifi still seems to function properly. Only when the bluetooth is actually in use (ie. listening to music or taking a phone call on the headset) does it seem to disrupt my wifi connection. If I turn my bluetooth headset off, wifi will work perfectly again without any drops.
Does anyone have any insight into this problem? I have tried changing radios, hboot, the works and nothing works.
Cheers

Bluetooth disconnecting

Howdy all. My HTC M8 has a strange bluetooth bug. It will connect to my car stereo just fine when I first start up. But after a minute, it will completely disconnect. Then reconnect about 10 seconds later. Happens every time and only started when I updated to Marshmallow. And one out of every three times after reconnecting, the audio on my device will completely mute/freeze. The phone itself continues to work fine, but no audio, even after disconnecting from the bluetooth. Only a restart restores the audio. Wondering if there is a known issue with the Marshmallow modem that can be causing this.
OK, let me make this simpler...
What images in the firmware zip can I flash to roll the bluetooth drivers back to 5.0 (Kit Kat)?

Intermittent Bluetooth problems

Hey guys,
I'm running Oxygen 4.1.3 with the stock kernel but sometimes when I try to turn Bluetooth on it says no paired devices available and when I come back out of it and back to Bluetooth settings the Bluetooth is still turned off. Every once in a while it works perfectly, I turn Bluetooth on, all my paired devices show up and it connects and functions normally.
Does anyone have any suggestions other than factory reset?
Thanks
