[Q] Root and sort Bluetooth out? - Xperia Z1 Q&A, Help & Troubleshooting

Hi!
I have severe problems with using Bluetooth on Android 4.3 (both .290 and .136) as I cannot get the handsfree system on my car audio to work on anything other than .257 (4.2.2) and I wondered if I rooted my phone (its currently on 4.2.2, .257) could I then copy the Bluetooth files from .257 to either .290 or .136 ? and therefore, hopefully get the Bluetooth working properly....
I have tried to use the baseband from .257 on a .290 rom (by flashing it with FlashTool) but this did not appear to work..
Any help and advice will be very appreciated!
Regards,
Alan

Correct me if I'm wrong. So your bluetooth "won't work" if you root your phone? Or...?

No, the bluetooth doesn't work properly on 4.3 in that I cannot use it with my car audio system using handsfree.. It works fine on 4.2.2.. So I was wondering that if I rooted the phone on 4.3. (290 or 136) I could copy or install the bluetooth stack from 4.2.2 (257) and get it to work like it does with the 4.2.2 (257/ rom...

[Q] Voodoo OTA rootkeeper 4.1.2 -> 4.3

Hello guys,
Today I got a notification of the .266 update available on OTA. MY question is, will Voodoo Rootkeeper help me keep root acces, or will it not work?
In the description of this app is stated it doesn't work for 4.3. I don't know whether that means I can't create a backup on 4.3 or I can't keep root upgrading to 4.3. Please advice
I dont believe Voodoo OTA Rootkeeper works with this update. You need to either find another way to keep root or root after the update with one of the many tutorails

It has less bus than 4.1.2

That seem to be a smart idea There are some bugs indeed but I do not have the time nor needs to change the ROM..

[Q] How to fix bluetooth broken after 4.3 upgrade

Bluetooth in my XperiaV was broken by the upgrade to 4.3, which I have performed using PC Companion.
It tries to turn on for a few seconds and turns off.
Have you experienced that kind bluetooth behaviour and found solution, which you could share with me?
I would be thankful.
EDIT:
FM tuner does not start too. It seems there is problem with a driver for IC responsible for BT and FM.
Did you ever figure this out? Mine isn't working. On Xperia T LT30A version

No. At first I have waited for some help from here. Later I have found an information about ROM upgrade for LT25i and LT30a, which is apparently on it's way [here], so I have decided to wait for the new ROM. I expect it will solve this and maaany other bugs introduced by the recent upgrade.
As to the other bugs, to list a few:
- FM tuner does not work,
- there are spontaneous restarts,
- Skype crashes instead of starting.
Interestingly it happen once that after one of the spontaneous restarts BT started to work, but WiFi has stopped. I was able to turn on/off BT, connect to BT headset and use it. As Wi-Fi is more important to me I have tried to make it work once again and when I eventually managed to do so BT stopped to work. So far I wasn't able to make it work once again.
If the timespan between ROM certification and availability for the newest ROM will be the same as it was for the current one, then it would mean we should get it within one week from now. I hope it will fix all the bugs.
I actually figured it out.
Using root explorer, go to data and rename the usf folder to usf1. Reboot the phone and the nfc should do an update.
Bluetooth works well on my phone and my wife's phone as well (two different lt25i which were upgraded from stock 4.1.2 to stock 4.3).
I see many complains about bluetooth, wi-fi, battery drain, volume bar, etc and I can assure you that none of the two lt25i phones suffer from that.
The only bugs we have noticed are:
- the camera video recording autofocus buzz noise and some low-light inability to focus
- gps may sometimes reboot the phone
- ocasional (and rare) reboots
Battery drain is similar to 4.1.2 and we are not even using Stamina.
(FYI, if you turn off Google location services you'll notice the difference)
Our radio works well too.
Maybe you have flashed a ROM which does not tune FM frequencies acording to your geography ?
I believe that many "bugs" reported are due to incorrect flashing.
My 50 cents...

What about 100% charge bug? (At 100% phone shut down-->no alarm at morning for example).
Did you notice this bug into your XV?
I noticed that on stock branded rom (official via seus).
No BT issues at all btw.

Is there a way to root 4.3 stock ROM with locked bootloader?

The only way I know of doing it, is downgrading to an old 4.1.2 rom and rooting, and then upgrading back.
I unlocked my bootloader because it was much easier

My 4.1.2 was rooted before the upgrade to 4.3. Upgrade has broken root.

You should still have cwm recovery. Boot into it by hitting volume down at the sony screen until it vibrates. Then install the root supersu package

Now I regret, I haven't installed CWM.
Is it possible flashing latest upgrade didn't succeed due to lack of free space on data partition? When it has finished there was only about 90MB left.
On the one hand it changes only system partition, but on the other it may use data partition for some temp data (although should use cache first place).
I hope that upcoming update will fix the bug. If it won't be the case, then I guess I will have to reflash ROM.
Does repair procedure of the PC Companion leave data partition intact?

Oh yes, I forgot to mention that "bug".
No, both my phone and my wife's charge properly up to 100%
Not an issue here...
That's why I'm surprised with so many of these "bugs", while I have two phones at home that work (almost) perfectly.
And with 4.1.2 it was the same story. People complaining about so many things, and I could see bothof our phones with no such issues.
I only had an issue with SD card corruption, which seemed to be related with overheating and bad contact in the card slot.
I had .145 firmware and my wife had .140 (we're now both on 4.3 stock) and the upgrade even kept all our settings.
FYI, my phone was rooted but locked BL (I just installed a couple of tweaks).
My wife's was not even rooted.
I think that if we use the phone as close as factory settings, life will be easier.
Anyway, I'm always looking for potential tweaks to improve my experience, and because of that I'm waiting for a root exploit that doesn't require unlocking BL or flashing code that doesn't come directly from Sony servers.

I have no idea. Have you tried unlocking your boot loader?

I'd rather leave it locked, as I don't need to flash custom ROMs. At least at the moment. So far KitKat based CM is not stable, stock KitKat is "under investigation" and stock 4.3 update, probably bug fixing release, is about to be available.

As the mentioned update (.199) has fixed only NFC issue and not BT and FM ones, I have decided to give PC Companion's "repair" a try.
To put it short - it did the trick. BT and FM radio are working fine now.
Apparently something must have gone wrong, when I upgraded from 4.1 to the 4.3 (.0.295) and there was free space shortage.
As I had not root I have used stock backup and restore app. It managed to backup and restore all apps installed from the Google Play (with data).
The only thing I am missing right now is a root.
I have not decided to unlock the bootloader to make rooting possible, because I do not want to loose NFC capability, my data (some sources claim even SD card contents would be deleted), Bravia Engine etc.

For most of the so-called "bugs" that these forums report, a simple PC Companion repair would do the trick.
This is the Sony recommended way to overcome issues during flash process.
You will end up with a stock rom, no root/UBL, but your drm keys will be back (important for Bravia Engine, ...).
From my experience, too much hacking = messy device.
Personally, I'll root my lt25i 4.3 device based on an exploit for locked boot loaders when it is found.
Until then... using stock with almost no bugs at all.
And so does my wife, which also has an lt25i with stock 4.3.
The only relevant bugs we found on 9.2.A.0.295 (yep, still waiting for latest ota update to be available :-/:
- camera background noise and slow focus issue
- gps random reboots

For rooting your phone just install any prerooted rom like nut;s rom or existenz
There is also another way of rooting but for that you need to unlock your bootloader so i think the above method of flashing pre rooted roms is easier
I dont have any problems with my bluetooth headset

[Q] What's the best way to update to 4.4.4 WITHOUT losing root with root apps intact?

Hey all!
I'm eager to upgrade my Sony Xperia Z1 to the latest and obviously greatest Android 4.4.4, but I've recently installed so many apps, both root and non-root that I do not want to do this over again. I finally got Timeshift Video working (took me longer than it should have, I'll admit) and I just don't want to go through the process again. So the question is: is there a way to update while keeping all data from apps intact, and will all root apps from 4.4.2 even work on 4.4.4 still?
Thanks in advance!

In order to keep your apps just do not select data before flashing. Now for the root I rooted my phone with a very strange way. I flashed the .108 ftf and then with adb i flashed the doomkernel(v21) to my phone. Then I booted up my phone and enter one of the recoveries (TWRP) select reboot and before rebooting it will give you the option to install super user. After this i powered off my phone (in recoveries reboot options) and connected my phone in flash mode to my computer. With flashtool i went to flash the .108 ftf BUT I didnt wipe anything and i excluded everything exept the kernel. When this finished I booted up my phone and it was rooted.
I just say what i did do not blame me for anything as if you follow my way you do it with your responsibility.(press thanks button if i helped :angel: )

Download flashtool
Download ftf file of. 157 kitkat for your phone's model
Install flashtool and drivers Google it also if you are using Windows 8 or higher some additional steps are required to install drivers
Switch off your phone
Once done open flash tool click on lightning icon select flashmode
Browse through your pc for downloaded ftf file select it and click on flash button
Now wait and once the dialogue box appears with phone's animation
Connect your phone along with pressing volume down button
Then once dialogue box disappears release volume button and let it do its thing
Then disconnect your phone and turn it on when flashtool says so in logs
Now you have kitkat..!!
I too, thinking of rolling back down to KK
Reason being battery drains faster, intense lagging in some apps, like what's app. Lag in games. Random reboots already more than my time in KK and it'd less than 2 weeks.
