i got the z ultra yesterday and when i updated it to the latest firmware wifi wont switch on and it reboots after 10 or 15 seconds. i tried repairing the firmware using SEUS and its still doing the same thing, tried flashtool and it was never resolved! im an xperia z user too, i know that wifi not opening issue happens if the modules are incorrect if you will use a custom kernel, that's what im experiencing, when i toggle the wifi it will be greyed out and it will start to reboot, then i need to activate airplane mode just to stop the reboot thing, and once i turn off airplane mode it will automatically try and activate the wifi and will start rebooting again. Can someone help? bootloader locked, rooted to change CDA on build prop to trick SEUS and still its f*cked up.

Yeah thats messed up man... when I've been beta testing that happens a lot, but not on a stock kernel...
Try flashing a different FTF.. like going back to .510... Here's a link to my thread containing FTF's for you to flash. Try those and see what you get. Often the modem's will be changed in countries official releases, but I'm not aware of anything happening as they are all supposed to be 'international' ultras. (unless its branded like american carriers do)

thanks dude, mine is taiwan CDA. i flashed back to .510 do you think i need try and root it first and just change CDA and update using SEUS? what CDA do you recommend? thanks for helping btw.
checked the link and yeah, i've used the .510 ftf u uploaded last night. please recommend a CDA that i can use.
Edit:
i rooted my phone and tried Hong Kong CDA, im now updating via SEUS. Hope it gets fixed.
Edit:

I would return to TW version on the latest version .532 and ask for change the device. It seems your phone have a problem with the .532 Wifi driver and setting. You are on stock so it should not do that.

That sounds like a hardware issue as described and when powering the wifi module it's effectively throwing a windows blue screen and rebooting. I'm sure there will be a diagnostic code you can enter into the phonepad to test wifi, if it reboots then you've got your answer, but service will know all that if you can't find a code.

like @SpyderTracks suggested.. if software does not fix it, then there must be a hardware issue. Take it back to the store if possible..

Hi guys!
I've got a Xpera Sola a couple of months ago, and it keeps random freezing and rebooting quite frequently,
at a time base of a dozen times a day, which make it unusable.
I've been waiting for new ROMs and hoping for a cure, stock 2.3s, stock 4.0s, and cm9s, but none of them works.
The only difference between stock and cm is stock do HANG/REBOOT but cm just HANG and drain battery.
While lost faith in new ROMs, I tried to figure it out myself, and here is what I found:
No reboot/hang in airplane mode (so it's the radio?)
No reboot/hand when ADB is pluged (so BAD news!)
My configuration:
Bare ROM, no additional apps.
GSM networked SIM card / no SIM card, makes no difference (I have no WCDMA card so can't test)
Wifi / no Wifi, makes no difference (maybe hang more often with Wifi on, but I'm not sure)
SD card (2G) / SD card (4g) / SD card (16G) / NO SD card, makes no difference
CPU governors, no difference
wake lock, wifi lock, accquired with terminal in cm9, still hang
Any feedbacks are welcome, need your help!
Thank you very much!
some updates:
the problem still there, tried cm to 213 and .54 Italy/China and munjeni's MIUI.
getting hung when using the phone only happened in stock or stock based roms, not in CMs.
stock based roms seemed to have a watch dog to reboot the phone in a 2-5 min interval, but not sure whether it's in kernel or in rom.
guess the hang happened when awaking from deep sleep mode, and no deep sleep no hang (such like when ADB is active and deepsleep disabled).
forget one thing:
witnessed one hang issue in air plane mode.
I assume you are on stock ROM, this is not normal. Did you try repairing with PCC?

Obviously none. Then try to reflash or hard reset.

Have you tried the last SlimFXP + Sliding kernel 3.2?
I had almost your problems, but not so often (hang or reboot every one or two days) and the combination indicated above improved the situation very much.
I'm still testing and it seems quite good: I'm using SmartassV2 governor.

HI ALL,
i have been facing a problem for last two days. I updated my Xperia P to JB using pc companion. It was working fine. Suddenly there was an issue in the morning the day before yesterday. It suudenly started to Reboot automatically.
First the logo of sony and xperia comes and dissolves. Then the default loading wave of xperia appears but instead of going to the lock/home screen it starts the booting process again and this process repeats.
I switched off my phone using lockkey+volume up. i tried to update/repair my phone using PC copanion and Sony Update service. Both case the latest software is downloaded and installed. But after installation when i try to switch on, it goes to the menu screen normally and asks me to select time format, language etc... but when it asks me to search for Wi-Fi networks if i touch on 'search for available networks' it falls in the same reboot loop again & the Home screen never comes..
afterwards, i skipped that step of WIFI and now it works fine.. but the problem is when i hit the WIFI it falls in the same loop. Now i am in a fix ... i dont know how to solve this and without WIFI there is just no use of this phone
the device was not rooted nor flashed before
What should i do? Try to flash my ROM?
PLZZ HELP ..THANKS IN ADVANCE

It's a long shot but have you tried to reboot your router?
Since it worked for a while, and you repaired the phone and it still exists, I am guessing it's not a problem that related only to the firmware.
Could be hardware problem.

Bootloops usually come from flashing a bad rom......... Never heard of this problem before....

my sister xperia P got reboot loop too.
even i can't flash it back via flashtool, beacause it's keep rebooting and USB debugging not turned on. please help.
what should i do now ?
Hi all,
EDIT: IT SEEMED TO HAVE FIXED ITSELF - MODS Please delete thread!
I have had my Sony Xperia Z Ultra for a while now and experienced many of the bugs read on this forum.
When I saw the .532 update for the HK version I immediately went on to flash it officially via the Update Service (mine is the HK version).
It updated fine without but I couldn't turn the screen off fully and the backlight stayed on continously draining the battery very rapidly.
So I decided to restore the device fully via the Official update service and this when the problem occured.
It started updating without problems but after a few seconds it just stopped and told me there was an error.
I tried it a few times to no avail and get similar result with the flashtool.
If anyone has any suggestions fire away.
Also, BL not unlocked, not root and neither custom recovery.
Many thanks

I turned my computer off and back on again and that made it work. Really randon
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
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
