[Q] 4.4 blutooth problem - Xperia Z1 Q&A, Help & Troubleshooting

I recently updated to 4.4 through Sony not rooted.

It cant find other devices and nobody can find my phone???????????
Help anybody

Try Factory Reset and if this not help Repair via PCC. This are the first 2 things what have to be done after facing some issues.

[Q] Headphones correctly detected only first time after boot, not detected after that

I am experiencing headphones detection problem with my Xperia Z1. Headphones are correctly detected first time after reboot. If I try to plug them in after that phone doesn't detect them any more (external speaker is used even after I've plugged them in).
I contacted Sony support and they suggested it might be Smart connect. I cleared it's cache. Didn't help. I disabled/removed it. Didn't help either. I downgraded to an older ROM (don't remember if it was 4.2 or 4.3) and it worked as expected. Then I downloaded fresh .ftf of latest rom. Same problem re-appeared. Tried with Kit Slim custom ROM (based on 4.4) and experienced same problem.
It is obviously a SW problem. Is there any app which would allow me to manually direct sound to either destination? I have SSH server running on my phone. Is there any way to do this via shell? Any API call that I could utilize? I have no experience with Android dev but I am SW engineer and I think I could implement a simple app like this if someone would point me in the right direction.
Thanks!
it's definitely something with smart connect. had the same issue some days ago...... unistalled smart connects updates and installed them again -> works!
Tried that already. Didn't help
I contacted Sony support again and they suggested to try PC Companion's repair feature. What will that do? How that relates to the fact I'm running a rooted custom kernel?
Thank you!
hm try to flash .157 with flashtool. after that flash trinity kernel via flashtool and fastboot -> should work like charm dont forger to save your data before that I did the same and it worked for me
Where could I download that?

[Q] Possible to restore stock firmware w/o root or unlocked bootloader?

Hey Guys,
So my brother recently received his Sony Xperia Z1 on a two year plan. When he received it, it was running stock firmware (android 4.2) and it was working completely fine. He then, using Sony PC companion, updated his phone to the latest official firmware (kitkat). But afterwards, his phone's microphone didn't work. He then called both Sony and his carrier asking what to do to fix the issue and they told him to restore the device, which he did, but that did nothing as his phone was still on kitkat and still glitchy.
So now the only option for him is to send it in for repairs, but that will take at least a month, and he needs the phone in the meantime. So brilliant people at xda, is there any way for him to restore his firmware to android 4.2 or another official firmware in order to fix the problem without rooting or unlocking the bootloader. If he unlocked the bootloader it would mean that he would never be able to send it in for repairs, which is vital in case it is not a software problem and a coincidence that the microphone broke at around the same time.
After the problem is fixed, I'll probably install cyanogenmod on it for him but he would not like to do that until we know we wont need to send it in for repair.
Thanks!
This is a guide to root the phone, it includes downgrading the phone... So you could just go ahead and do that step only. Good luck.

wifi problem wiht xperia t and sw2

Hi guys, i have sw2 and xperia t running stock rom 4.3, when my phone and sw2 are connected wifi on my phone doesnt work, when i turn off bluetooth wifi works again, how can i fix it i even did factory reset, i would like to stay on this rom, any solution?
There's no solution for this, I had the same problem like you and I tried everything to fix that problem. Nothing helped so I moved to 4.4 and now I'm on 5.0.2, no such problems
What did you try? 4.3 is running decent so i wouldnt like to change it i was thinking about downgrading to 4.1 but its kinda mehh, what rom did you install, was it buggy?

Is it possible to downgrade only Bluetooth ?

Hi
I have a problem my Bluetooth connection to my car (BMW E91 Nav Prof) dosnt work since the Android 6 Update. It works well again with a downgrade to Lolipop but the Perfomance etc is much better with Marshmallow.
Is it possible to downgrade only the Bluetooth files?
Already tried a lot Apps to fix the Problem, disconnet and connect the phone many times, delete Cache and use some other settings nothing helps, just the downgrade.
I got the newest official Sony software and root acces.
Could be nice if somebody help me to fix the problem

Unfortunately I don't think so.
But to be honest I would rather have stock Lollipop than Marshmallow lol.
But if you need Marshmallow then try Concept Software.
