Hey guys since i flashed the new firmware via flashtool, my NFC option is really weird in settings. It is turned on after reboot but if you then press it it goes off and you press it again it blinks for a second then goes out again. I gotta reboot to make it normal again!

For those who update to android 4.3 via Firmware-Over The Air (FOTA) and having sharp eyes may notice some bugs due to the leftovers of /data of android 4.2.
Here is a list of bugs I found :
- Sony Select takes forever to load
- Xperia with Facebook takes forever to sign in and load
- Ui layout issue when uninstalling app
The first two issue is rather easy to fix.
AFTER FOTA A IMMEDIATE FACTORY RESET IS COMPULSORY (internal storage need not wipe)
Press thanks if I helped you
Also Sony have completely knackered the Bluetooth stack... When I first got my z1 it was on 4.2 and would connect to my car audio system (navi 800 in a 2011 Vauxhall insignia) with no problem, allowing me to make and receive calls using the voice control on hands free.. After the update to 4.3, it connects but will not make or receive calls.. I contacted Sony who more or less said it was the audio systems fault! They obviously have done zero regression testing at all! I have tried the audio with a s3 which was running 4.3 upgrade with no problems.. If Samsung can make it work why can't Sony!
If anyone knows of a fix for this I will be extremely grateful!

Did you try the factory reset? Before that, I would delete the from phone from the car and the car from the phone, then re-pair. If that doesn't work, factory reset. If that doesn't work, reflash the 290 FTF.

Hi,
Thanks for the replies.. I will try that today... What is the best way to reflash the ROM? Using the Sony companion or the flashtool thingy? Also, what ftf file do I need?
I also remember that there is a red button by the sim card slot to reset the phone? Or do I use the options in setting?
Sorry for all of the questions!

Have tried the delete fone from car etc and repaired the devices and factory reset/ and also reflashed using the Sony companion but still does not work! The devices pair but I still cannot use the hands-free facility. WELL DONE SONY... NOT!!!!

This button is only to force the phone to turn completely off. It does not reset anything. Make sure that's what you tried for the reset.

The only proof is really to flash back to 4.2.2 and prove that's what did it. Sorry, there's not much else I can recommend here.
I installed a fresh with flashtool, wiped all data and still have that 3rd one with the UI layout when installing and uninstalling apps.

I use a bluetooth mouse with my Z1 and it's no longer functioning properly with the update. it stutters across the screen and is useless for anything really. Also movies seem to stop and restart or close. I've done a factory reset and it's still the same. I haven't tried my bluetooth keyboard yet. I use the mouse daily and hook up via hdmi so this is a major inconvenience. Anyone got a fix for this please?

Unfortunately, you may be up the same tree as @nalab1 and need to flash back to 4.2.2 to see if it's strictly a 4.3 issue. Otherwise, the only thing I can suggest is to cast a wider net and see if any other phones are having issues with Bluetooth and 4.3.

Hi,
I have just had a look at the FlashTool Guide and saw this -
- Red: Firmware selector to selct the firmware you want to flash
- Blue: this will display the firmware content
- Green: Wipe options, you can choose to wipe certain things here
- Purple: Exclude options, this is to exclude content like kernel or baseband from flashing
- Orange: verification check, you don't need to edit this option
Are there any recomendations as to what to select in the Green/Purple/Orange sections?

Yesterday I updated my Xperia T to Android 4.3 via Sony Companion Software. My phone is not rooted. Everything apperently went fine, but after the Update process I wanted to turn on my Wifi, but it did not work. I tried that from the quicksettings and form the settings directly. The button remain grey for a certain time and the turns back to off.
I turned off my phnone and on again, but a white triangle with a screw came and the phone remained in that status for more than 6 hours. After that it turned on, but the Wifi problem remains. Regarding Bluetooth, that works fine.
What I noticed is that when I check the phone info and the Wifii settings, no MAC Adress is listed there for Wifi. I don't think its a hardware problem, because everything was fine before updating.
What should I do? I am afraid to turn my phone off bcause it could go back to the white triangle remaining for several hours in that state. I dont think a factory reset would help, because there seems to be an update problem and I would like to rather not loose all my settings.
Any help would be very appreciated, because I urgently need wifi in my university.......

The ftf file is the stock Rom, you can find it here on xda. Flashtool also. Flashtool only works if you have windows xp, vista 7 or 8. Not on 8.1. Repairing it using pcc should be easier though

Unfortunately, reparing it with PCC did not help and I am quite desperate. I bought the phone last year as a used one. I am quite a newbie in this field, but could it be, that the rom installed is an altered one and a normal update via PPC leads to this Wifi problem? Normally that should not be the case, but how can I find that out what is causing the problem and what must I do to overcome this drama of mine. I whish I didn't perform that update, because everything wAs working fine before.....

A factory reset would definitely work. You don't know how many times I've seen people (even with different phones) have problems like these because they change their Android version and/or flash different ROMs without wiping their partitions, i.e., doing at least a Factory Reset. If you were rooted you could try deleting the "wpa_supplicant.conf" file in /data/misc/wifi. The problem is, since you're already on 4.3, there is no sure way to root 4.3 unless your bootloader is unlocked. So unless you find out a way to backup your data/settings, you're either going to lose it all when doing a Factory Reset, or downgrading to 4.1.2 (to root), or even flashing a stock 4.3 FTF, because I'm sure your problem is that you haven't wiped.
Hi!
I just recently bought the Xperia Z1 (C6903) and I have a really strange problem. Whenever I make a call or I answer one I have to wait 3-10 seconds before the ear speaker turns on. The other side can hear me perfectly, but I can’t hear them. The problem doesn’t exist when I’m using a headset. After I start hearing the other side the sound quality is perfect and there is no problem until another call. I am running official 5.0.2 ROM version 14.5.A.0.242. I didn't root, didn't unlock bootloader, just did OTA update. Any ideas?
Sorry for my English
So just in case someone has the same problem here is a possible fix i got from official Xperia forums and a hisory of other bugs and problems I encountered:

Hi,
thanks for posting, but I am encountering an error when trying the "Repair my phone" option - I apparently cannot install the Sony Mobile Update Engine from within PCC (error 0x80070067), so I tried installing it manually, but I'm getting another error: "Access control error (inherit): Invalid filesystem path missing". I'll try doing that on my laptop and report back.

hi
i have a problem after i upgrde my Xz to 5.0.2
frequently i have no sound on calls
now i have 5.1.1 but problem still there
i think its a software issue and i want to downgrade to 4.4.4 [last good condition]
as i read in xda, i should flash 4.4.4 rom before flash, i should back up ta.partition and for that should have root access,
how can i root my 5.1.1 [10.7.A.0.222] [C6603][LB]?

Well, a direct 5.11 root isnt available yet. repair phone via pc companion repair, then flash with flashtool the 5.02 FW, root using kingroot then replace it with SuperSU (there is a thread here someplace) install dual recovery, then flash a pre-rooted 5.11 FW. It works like a charm.

No, you dont need to unlocked bootloader.
And you suspect any reason why there is no sound? water damage? maybe headphone jack mess something(and phone think that HP are connected)
or you drop it?

i didn't use the phone under water or wash it, and don't remember any major cause to damage my phone,
i should mention that i have sound problem only on voice call, loudspeaker is ok, musics are ok, headphone is ok,
already know that the problem is not a software cause, as i said"when i press phone's back hardly with my finger during call the voice goes ok"
you said that no need to unlock BL, how i can flash the phone without unlocking BL?
Hmmm... you said that its HW problem, but like they say "everything is possible" so maybe secondary mic is messing it(2% possibility but still...)
DId you tried messing a bit with "Noise Reduction" and "Volume Boost" in Call Connectivity settings?
Also when you test it via service menu(*#*#7378423#*#*) service tests->earphone its working just like in calls(when you press back of your phone)
About Flashing:
Here you have tutorial:
http://forum.xda-developers.com/xperia-z/general/tutorial-how-to-flash-stock-roms-t2240614
latest flashtool you can get from here:
http://www.flashtool.net/index.php
If you need ftf ROMS just use App "XperiFirm" that you can find in Flashtool folder(or just use icon in main app).
Note that new version of Flashtool have "firmware" folder in your Personal Folder(where you have pics, vids etc) its hiden folder called ".flashTool"
Also before you do anything, install drivers from Drivers folder: select Flashboot drivers and Xperia Z from the list. THEN turn off your Phone and plug it to your PC holding down button. PC will install your phone as a new device, so you would not have problems when you use Flashtool(one time when flashing it show popup about this drivers and messed installation)
First time of using Flashtool is weird and look complicated but after few times its just like using any other app :]

when i use (*#*#7378423#*#*) service tests->earphone , with "Noise Reduction" and "Volume Boost" both off/on
earphone is ok(i tested it several times no need to press back of phone)
i downloaded the flash tool(emma) from sony's website but every time i try to launch app it goes for download and
after downloading more than 500MB with an error app will close
So if in service test earphone work, I think its problem with volume or one of setting(vol boost etc). Service test use quiet sound, but most of time when you make a call, its trying to get best volume possible, and speaker is probably damaged and it blocking coil/membrane of speaker when it get high level volume/tone. Maybe there is dust or something that is stuck there.
Small chances for that so I assume its just factory bug of earphone and it was easily damaged.
BUT ALSO it can be software related and falshing and messing a bit with volume and tone of earphone would help for a while.
Use links that I posted, dont use Sony flash, download flashtool from official site(http://www.flashtool.net/index.php) and read tutorial from link that I posted. Everything should be 100% working if you fallow it.

thanks buddy for your help,
i haven't any problem so far, after using that test.
sometimes when i had no sound on calls by tapping volume keys instantly i had voice but for less than a second.
i can't figure it out, its software problem or HW?
im a bit afraid to flash my phone i dont do that before and i dont know its necessary right now?
i dont want lose official updates.
i heard about repairing with sony pc companion i dont have such tool on my official pc companion downloaded from sony, also all tools(such contact sync, media sync, etc.) need update and i cant update them , they dont start to update
if i flash without unlocking BL can i receive official update?
and which FW you suggest to flash a custom 5.1.1 or downgrade?
You dont loose any official updates when you flash files via flashtool.
Its work the same as Sony Repair Tool, that just flash clean "system" folder to your phone, Its like replacing Windows folder on your PC.
But flashtool can flash whole ROM, with data, kernel and system folders. And as I said, use links that I posted.
You dont need to download custom FTF files, just use XperiaFirmware tool that is provided with Flashtool to download official and clean ROMs.
Fallow instructions from tutorial, install drivers. and make sure that you make backup of files from internal memory of your xperia and sync all data you have(contacts etc). because when you flash full FTF file, its like having new phone, its clean installation.
But yes, you could check Sony repair:
Here you have instruction how to use repair:

there is no DIRECT way (YET) to gain root access on BL locked
but there is a way to SAVE all the downloading of 5.0.2 and 5.1.1 (2.5gb of data)
since you are on 5.1.1,
request developer.sony.com boot unlock code,,,,
then flash kernal (boot.img+recovery ) and flash superUSER as explained
