Problem with bluetooth - Xperia Z2 Q&A, Help & Troubleshooting

Hello all, i m using xperia z2 since one and a half year. Six months before i also rooted my phone and have been using niabocs existenz rom. All was smooth until yesterday i dont know what has gone wrong with bluetooth. It can receive files but i m not able to send any file to another phone. Weird thing is i can send and receive both using my windows 7 laptop.
I have tried clearing bluetooth share data and restarted phone many times. But it just gives me a message file not send. I haven't done any updates or added any sort of app after which this cud have happened.
My doubt goes in the settings but i dont knw where. I can try to flash the rom or factory reset again. But i thought if someone knew what is wrong can help me before i reset it...
Thanks

Cant call, text or recive calls

Here is what happend:
So this is my sisters phone and Im trying to fix it for her. The phone was locked when our little sister failed to open it too many times (my sister had the graphical lock enabled). My sister then took it to a phone store which managed to fix the lock (updating it from 1.6 to 2.1) but in the same process they somehow managed to make the phone block calls and text. They told her that it had "been blocked"..?
She after that she cant send or receive texts, cant make or receive calls but she can surf via 3G.
What is wrong?
Here is what I've tried:
I'm a big andriod noob since Im a iphone user but I can use google and I've jailbreaked/unlocked iphones many times.
So I've tried both to re-flash (with flash tool) the phone and to restore it with SEUS. None worked. First after using the Flash tool the phone got stucked in a boot-loop. At this points I tried SEUS but it would just get stuck and then tell me that the restore had failed. At last I managed to get back into a working phone when I went down to 1.6 using ROOT_F3V3 (I dont know if I did the whole flash procedure right but right but when it was done the phone started fine but the text and call issues persisted). So then I tried SEUS again and this time it worked so now I got a fully updated and restored phone. BUT STILL: it cant text, make or receive calls. Is there any next step? Any method which I haven't tried yet? I stumbeled upon something called xRecovery. Could that help me? Or is the phone pretty much bricked...
Please help me

Try it with a different sim card to make sure that it's not something related to the mobile account.

Go to Settings > Wireless settings stuff > mobile provider > Choose your network manually
I dont know how it's called, in english because my phone is in dutch. But somewhere there you can choose manually a network.

Facing a really annoying problem of automic rebooting. Badly need HELP!

I am facing a very annoying problem: my x10 mini(unrooted) automatically gets restarts.
Some of the days it works fine. But once it gets restarts then it restarts atleast 3-4 times a day. I have tried to reinstall the android firmware but still the problem prevails. I keep the phone memory at 21-22MB level, is the problem because of this( But I want to tell you 1 thing that I bought the phone in november and in feb end my phone was not switching on ,then I went to SE service centre they reinstalled the firmware and the problem was solved. Since then I am facing the problem of rebooting, before that it worked fine. I used to keep the phone memory around 2mb in the initial days of purchasing and it worked fine even in 2mb so I guess low phone memory is not a problem. I rooted my phone in november but when service centre employee reinstalled the firmware then I lost rooting.i.e. Now my phone is unrooted). Can the problem be because of SIM card or SD Card(corrupt files which I am aware of) or it is because of some other reason?
I dont want to go to the service centre because I feel that they will just reinstall the firmware which I already have done. It would be great if you could tell me any solution. If not the solution then a user friendly and so technical language using app which show the log of my phone so that I can figure out what happens in the system. But I really want a solution. Please guys help! Hope you guys would bring all your experience into play and help me.

Well ..people will need some more specific info ..like are you on the latest SE update ? what programs did u install (seems u did install quite a few as ur phone memory is ~22 MB ). Anything you noticed when it reboots ? Like while doing some operation or running something in particular when this reboot happens ?
Why dont you do a fresh flashing of the latest update through SEUS (not PC companion) and then just stick to the stock ROM (without installing anything else) for 7-10 days and see how it behaves ?
You can always take a backup of ur essentials like SMS and contacts (if you are not syncing ur contacts with google ) before you flash using SEUS.
There are ways to check the logs (using logcat ) but not sure how much effective it might be as u might not be in a position to check logs everytime when your phone reboots.
Hope this helps. Really there was very less inputs available for giving any solution.
I am having the latest android firmware. I updated the android firmware by downloading a firmware file avaible on the sony's website, I don't know what it is called but I surely didn't used pc companion for updating. There is no specific app which I am using when it restarts.
I will give any necessary info which will help you to suggest a solution.

you cannot just download a firmware from SE site ..it can be done only by two ways one via PC companion and the other by SE Update service. (SEUS)
And yes , it would be better to reflash through SEUS . It does seem that you have installed lots of things ..better forget them now and just use the stock ROM from SE.

[Q] S3 Text messages suddenly disappear. Return after reboot

I'll get a new text message & go to read it but then all the conversations have disappeared & I can't send or receive any new ones. Once I reboot the phone they all reappear.It happens 3 4 times a day. KIndly Help. I am using 4.1.2 XXEMA2 Official.
Factory reset and or flash stock firmware .
jje
same with me isnt there anyother way without installing stock app factory reset doesnt help
I'm having the same problem. Seems to be getting worse. Used to be about once a week, now almost daily. Doesn't matter what messaging app I use, happens with all of them, including stock. Very strange.
I still have this problem, any solutions yet?
same issue running stock unrooted phone.. started happening a week or so ago but now its multiple times a day. factory reset is not working.
Sounds like your DB files are getting corrupted and are rebuilt on reboot. Might need a full wipe and reflash of the roms your on
Wayne Tech S-III
its happening to me and im on synergy rom. and its also happening to my brothers note 2 and hes stock everythiing, not even rooted. must be a samsung thing. if anyone has a fix id like to know tho since its happening almost every day now.
Its happening to me also, S3 completely stock, un rooted
we really need help here
Post 2 and post 7.
Or contact Samsung .
jje
Any fix for this?
I think it has something to do with Play Store.
Every time I restart my phone after they disappear, play store has new updates available.
Had the same problem. Hard reset solved the problem. Vol up + home button + power button. Select factory reset. And voila.

wierd wifi problem

i am on jb 4.1.2 i am rooted also last night i messed around with some files and got frightened and did a factory reset all things are working but my wifi is acting kinda wierd its in a loop ones switched on its in a loop and it neither switches off or on
plz help i think some libs or something like that is missing but can't fig it out
can some one plz help me as its my fathers phone and he's at the verge of killing me plz help
If you messed up with some system files, then factory reset will not help. to restore system files you'll have to reflash the ROM.
I exactly had the same problem... I had decided to go to service center..at last I just flashed samHDV2 ROM AND...WHOA!IT STARTED WORKING.

[Help] Lost IMEI after update to , and downgrade

Well, received my Sony Xperia Z Ultra C6833 a couple of days ago.
Received a notice on the OTA, upgraded to 14.1.B.2.257
I encountered random restart issues whenever Wifi is activated, so I thought, fine.
I finally have access to my computer, installed the PC companion, it prompt me with a new 14.2.A.0.290 update.
Again, I updated my phone, hoping it'll fix the Wifi problem.
After restarting, I did a test, as usual. Wifi problem persists, and what's worse, a new problem. Wifi and Playstation 3 SixAxis controller connected using bluetooth didn't play nice, caused my phone to reboot.
I know a lot of people downgraded the firmware back to the previous version, with NAN backups etc.
And some even managed to restore their IMEI back to normal.
But for my case, I haven't root my phone, attempt to downgrade it using Flashtool, lost my IMEI.
Seems that I have no choice, but to return it back to 14.2.A.0.290 praying that it works, and I still can't see my IMEI.
No, I don't have a NAN backup. That's the part which gave me a headache. I've messed around with HTC one X (a year ago), never had this problem problem before, and it's something new I've learnt from you guys today.
Tried cyangenmod's boot.img, doesn't do me any good.
Anyone managed to recover their IMEI here?
Otherwise I might have to get it back to the dealer for a replacement.
Update: Thanks to krabappel2548's guide, I've managed to flash it to 14.2.A.0.290 again and got my IMEI back, but SixAxis still won't play nice with Wifi, and the problem with random reboots while Wifi is ON still persists.
we have the same issue, mine happened during the old update, after ota wifi gets stuck, wont turn on and reboots the device. upto now its still not fixed. 3 updates have passed and still the issue persist. hope you find a fix it will help me too. tried everything from downgrading, flashing custom rom,kernel, upgrade, unlock, relock but still cant fix it
I guess i'm not the only one then. I can live with the wifi issue for the time being as long as i stick to using data. But i fear it's going to affect tethering should i need that.

Read it the moment I discovered that my IMEI is missing.
I tried reflashing excluding the baseband, doesn't work for me, right after i realized i have a missing IMEI.
Read up on the android emulator, but haven't tried it, as my computer is kinda old, took forever to run it. Will try it once I get my hands on a faster computer
Bah. Crashed when I tried to use my qx100 which i've just received. Haha. Anyone else has any fun with qx100 and z ultra combo? The Z ultra almost reminds me of my ex-girlfriend.
Meanwhile, I can't wait for kit Kat, and hope they really squash these bugs
The best thing would be to contact Sony and make them aware of this bug. Losing your IMEI by simply updating should never happen and it's quite a serious bug.
Actually i lost it after downgrading. Downgrade is simply because of phone keeps rebooting after I turn Wifi on.

I certainly hope so too.
Hope it fixes the rebooting issue with WiFi enabled.
Or the Google Play Edition port if it does fix the problem too
Anyone tested the new update yet? Does it fix the wifi issues with crashing/rebooting?
ok so i purchased my phone on amazon and got it somewhere around feb 25th, i got a message on the phone to update software so naturally i did, then i discovered what rooting does and i decided to follow some youtube instructions to flash my phone to an earlier firmware the link wasnt working so i found another which was C6802_14.1.B.0.475_GENERIC Hong Kong.ftf after flashing this i lost my imei its all zeros and i then tried flashing C6802_14.1.B.1.526_M3dD0g.ftf with no luck so im trying to find out what the updated software was that i must have downloaded when i first got the phone given the date i had recieved it im thinking that the 14.2.A.1.142 is the correct one that i must have updated to, i was running version 4.3 jelly bean before all this happened i also have this problem where everytime i turn off the phone and turn it back on it is in the chinese writing again and asks me to select my language again anyone know what to do short of return the phone while i still got time my internet is extremely slow im tired of it taking 4 hours to load a new ftf just to find out its not the right one ive heard some where hving success with the 290 getting their imei back but im thinking thats the software they started with or updated to to get it back so i have no idea which one i started with or which one i updated to all i know is the date i got it and that possibly its the 14.2.A.1.142 looks really familiar im downloading that one now so we will see what happens and i also read something about flashing excluding the basebands so if that is part of it please make it as clear as possible im obviously a noob but im learning quick
Pleas dont ask the same question in multiple threads.
See my reply to the other thread you necromanced
