So some time back I made a thread regarding a problem I was facing. My phone would randomly freeze up and restart on its own. I tried hard resettig, repairing using PC companion, flashing using Flashtools , changing SIMs etc. but nothing seemed to fix it. Then I had to arrive to the dreadful conclusion that it was a hardware fault. But 2 days ago I got the bright idea of flashing an older firm ware version (17.1.1.A.0.438) using flash tools without wiping internal data and now the problem is 100% fixed. the phone hasn't restarted even once after a 3 full days of heavy use. So with this I can safely say that the probem is with the 17.1.2.A.0.314 firmware. Has anyone else had this issue? because my friend also owns a z2 and his phone works just fine with the 17.1.2.A.0.314 firmware. Any ideas how to fix it?

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.
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
Hello,
So yesterday I just solved my own issue of not getting any LTE signals by reinstalling the FW.
Today, I followed the advice of a user to restart the phone using PWR + VOL UP buttons to get the smoothness back. I did just that, phone became smooth again with the phone registering on LTE network.
But what happens now? I can't connect to Mobile Data AND can't make phone calls. I can run USSD code to check my balance and can receive calls just fine but cannot make phone calls.
Any ideas? Do I need to reinstall the FW again?
Model: D6503 FW: .314
Try flashing the baseband for your firmware and see if the problem persists.

I actually tried repairing it via Sony PC Companion application on the PC but to no effect. I'm suspecting it could be a HW issue but what baffles me is that it used to work fine (apart from the LTE issue) and only after I tried repairing it yesterday did everything work correctly and wham in the morning this happened.
try to flash the latest FTF again using flash tool..and check if it can help
hi i got a z2 this week and everything works fine just this one annoying issue. The home and recent apps on screen keys are laggy. Sometimes they work good, most times they lag. The back key is fine.
The phone shipped with 4.4.2 .314 and had the issue right out the box. I updated to 4.4.4 the same night and no change. I downgraded back to 4.4.2 and same issue. Did factory resets etc.
Is there any official word on what is causing this? I live in the Caribbean so sending this to a repair centre is out of the question. Just hoping it's a software issue that can be fixed.
Any help?
Repair via sony PC companion
I found the 4.4.4 update can bug a tiny bit and will slow down heavily, repairing should fix this
if i repair via pcc will i stay with 4.4.2?
i dont want it to update to 4.4.4
Downgrade via flashtool buddy then this problem will be solved
i already downgraded using flashtool.
i was on 4.4.4 and downgraded to 4.4.2. The issue is there on both firmwares.
should i try another version of 4.4.2? if yes, which build number??
okay so here's what i did
initially when i first got the phone it had 4.4.2 .317
i had done the ota update to 4.4.4 and i got all the
popular bugs; camera lag, low notification tones, call problems etc
downgraded bk to 4.4.2, keep in mind the lag has been here thru all this, no matter the firmware
so today i thought id try doing the software repair via pcc. This updated the phone again to 4.4.4. Just this time none of the previous bugs are there and i am happy to report the home key lag is completely gone. The recent apps key had a verrryy tiny lag sometimes but nothing as noticeable as to how it was.
After this i am convinced it is a software issue and hopefully another update in the future would fix it completely. But for now im satisfied.
Hi everyone,
I have a really annoying issue for a while and I hope someone can have a suggestion.
When i turn hot-spot on, my phone freezes and reboots itself, so i cannot use this feature, however if I connect it to my computer i can share my data by Bluetooth.
More annoying issue, if I try to connect to wi-fi when my data is on, it freezes and reboots again and after that I can connect, but if I disconnect somehow, it reboots again. When I turn the airplane mode on, there is not a problem..
Has anyone of you experienced such issue?
Thanks
Sounds like a corrupt system, probably network driver or baseband
SInce you don't mention anything else I suppose you're on stock ROM , still locked bootloader, no magisk and all that. Simpliest way if your not familiar with ROM and boatloader handling is probably to do a total reset to start with followed by an update. Xperia Companion can be used.
If you're famiiar with ROM handling you may get the latest ROM from XperiFirm which you flash with Newflasher

Hi pergoteborg,
Thank you a lot for your concern.
You are right, I am on stock ROM. I have tried to do a total reset, but it didn't work.
Moreover, I am living in Italy and using Tim Italia, few days ago I was in Austria and in there I did not have any problem when I connected to an Austrian operator. I tried with a different TIM sim card in Italy, it was same. I will try with a different operator as well, but I have not had time yet.
Does it pop up anything on your mind about what could cause such a strange problem?
Thanks in advance.
Regards
