bluetooth not working after update

i updated CM11s and now bluetooth is not working anymore.
if i try to turn it on, it tries to activate bluetooth, then goes back off.
a full wipe didn't solved the problem, but it works with a clean rom (i tried mahdi, but i had to restore backup since monday i'm leaving for holidays and i don't have time to restore all i need on the mobile now).
i know i'm not giving many infos to have some help, but if you give me some directions i can try to fix it.
also, is it possible to reinstall CM11s with twrp or just through fastboot?
thanks!
I also have trouble with Bluetooth.
It tries to send file but either the app crashes or the file can't be sent.
Any info in that?
seems like noone has this kind of troubles
Hi! I just ran into the same problem: after upgrade to Cyanogen OS version 11.0-XNPH05Q, my bluetooth connection turns out to be unusable.
It first seems to connect (after "search for devices" is hit), but immediately when the call is initiated, the connection drops out (nokia BH-105).
Will check with my car installation too.
Is it possible to downgrade to previous Cyanogen OS version - I even don't know, which one was it... but at least it was working well!
Also having troubles with Bluetooth and my car-system since the 5Q update.
Before latest 5Q update everything works fine, but now neither of the devices can see the other one anymore
already deleted existing pairing in my car-system, but can't set up new pairing...
wondering if change of kernel can be a solution tho?

[Q] Push Notification Issues

Hi all,
I recently updated to 5.0.1 using the RUU, ever since I do not get push notifications. I am hoping it is something simple and not related to the 5.0.1 firmware.
I tried turning off the sleep mode to see if that fixed the problem, but it doesn't seem like that is the issue because I still don't get push notifications. I also checked all my in-app notification settings and they seem fine.
Does anyone have any ideas what the problem is?
Your help would be greatly appreciated.
It is most likely a ROM issue, firmware shouldn't effect is. Maybe make a backup of your current ROM and do a factory reset to see if that fixes the problem

[Q] Wi-Fi issue on 5.1 stock

Hi, I have a big issue on my Nexus 5 runnig L 5.1. Basically, I made some mistakes flashing various rom/kernels so I had to wipe evrything and flash the stock rom in order to fix it. Evrithing went fine, but now my wi-fi doesn't seem to work. I can't see any wifi network.
I have unlocked bootloader with the latest twrp. Hope you can help me solve my usse. Thanks in advance!
Turns out it wasn't the issue, but I managed to fix it. Basically the 5.1 hates wi-fi on channel 12 or 13, so I fixed it changing my router's channel from 12 to 10. So I leave this post here, just in case somone alse has some issue. You may close.

I really need help! (wifi issue/downgrade issue)

Hi everyone
Please help me out!
So I had a weird issue with my hw2 that it couldnt find any wifi network right after pairing to a phone
But for some reason after I updated my watch to android 8, this issue was fixed and I could use wifi...
But I had to factory reset the watch because I also flashed official oreo on my phone, and after factory reset the wifi issue came back!
So I want to know if there is a way to downgrade my watch to 7.1.1 and upgrade it again and hope that wifi would work!
And also is there anyway to flash custom rom over bluetooth?(cause there is no wifi)
Really need help working this out and unfortunately Im not a developer to see if I can read any logs or anything...

hello, very strange your problem, you should try to ask in the ROM section, maybe someone will deal with your problem, sure it is not a hardware problem?

Broken bluetooth after perform a OTA

Hi guys i have a problem with the bluetooth after OTA 10.5.7 to 10.5.8 (Europe version).
My bluetooth was broken, and show "activation..." and turn automatically in loop.
The problem is that activation of bluetooth isn't possible after OTA.
Does anyone have an idea ?
Hi. I also updated to 10.5.8 my EU version. Just tested the bluetooth. No issues here with me... Sorry, not of much help
Ok I will try to port the rom to fastboot and make a clean flash (without wiping Internal Storage). Thank's for you reply.
Doesn't work, I have reinstalled OOS rom fully.
And bluetooth switch to on/off without any reason.
I have tried :
- Reinstall Rom
- Delete network data
- Stop bluetooth app clear data and cache and reboot
All doesn't work
Full flash with MSM if it does not work it's a hardware failure ?

Hi @TekCoco , I found this thread only now, but I also have the same bt "activating" loop.
It started to happen to me last October when I updated via OTA 10.5.8 to 10.5.9.
Now I updated to 10.5.10 but sadly nothing changed.
It's been months since I cannot use BT at all.
I also opened a thread at the time: https://forum.xda-developers.com/t/bluetooth-not-working-after-ota-update-to-10-5-9.4183671/
How did you manage to solve that?
Thanks
