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
Hey guys!
I'm currently getting the "not registered on network error". I have tried any; if not all threads on this issue to no prevail! It started when i flashed my phone to a deodexed version of the stock firmware for my phone.
What i have tried;
Used my simcard in other phone (Works fine)
*#06# brings up the same IMEI string as the one underneath battery
Using another simcard in my phone doesn't work
Used Kies Emergency Recovery to flash my phone back to complete factory reset
The strange thing is, i then thought after my efforts, i've had a hardware failure. But when i scan for my local networks, i see them just fine. Which would presume the antenna is operational. *see attatchment - Screenshot_2015-01-09-02-30-32.png*
Try patched modem and kernel, restore efs backup.

Thanks for the reply.
I think it's on it's way out. The phone is touching 3-4 years old now. One of the first to receive the phone. It seems to be a power issue. I did the above solution yesterday evening which didn't work. However, the phone IS currently working perfectly above 45% battery. Have you ever come accross this issue before?
Is the battery swollen? Try another battery.
Well as the title says.
Just rebooted my s2 and now when I try to do anything it says "insert sim card to access network" imei is fine serials fine and even shows signal bars but soon as try to make a call to drop signal and network completely....
have restored efs folder and even dne a repair.
changed base bands
reflashed new rom
tried different sims(and networks)
and still nothing
Odd that it happened after weeks of being fine and then just did a reboot and then this all happened
any ideas folks as to next move?
please someone must have an idea or two. to offer!
Well looks like I have fixed the issue after many hours of frustration..
Still have no idea what happened to cause issue in first place..
What I did was refresh my original backup
flash original STOCK rom via odin and this seemed to have fixed it. Are there any friggin better loctaion for these files as took 8 hrs to down load the damn thing!?
now re rooted, flash custom rom, flashed custom kernel of choice and than restored back up
everything seems ok(though my imei is incorrect now as says 004999010xxxxxx ,but am concerned it will happen again. Had flashed a modem several days before and updated a few apps . but at time of the issue occuring was just clearing caches then a reboot..
This has be happening to me the last couple days. I've done no changes to the software, I did a screen replacement a few weeks ago. Sometimes Wifi will turn on after a while or the SIM card will read and connect to LTE. Trying to decide if the phone is on its last legs or not. I'm on BareCee ROM, have always only used engine95's modified ROMs. Tried flashing the latest modem and the latest partitions if any changes. Also tried deleting the /data/misc/wifi/ folder as suggested in another thread stating a similar SIM issue with no luck.
Can you fix that?

Hi, please tell me if you fixed that problem, I have exactly the same problem right now with my D851 T-Mobile, at first the phone says no sim card, but the sim works with other phones, and I use the phone with wi-fi but since yesterday the wi-fi won't turn on, I did the most common steps, did a restore wiping all my personal data and apps, and installing the original firmware. And nothing happens.
Hey everyone, I'm hoping someone is able to point me in the right direction.
I have an S9 Plus with TWRP installed and DevBase v5.9 as the ROM. I have made two backups using TWRP, one from when I first got the phone and a more recent one (within the last week).
When I first got the phone I removed a lot of the bloatware that came with it (Samsung stuff and other junk). After using the phone for a while I realized I needed to keep a couple of the Samsung apps, mostly Samsung Themes and Galaxy Apps (to keep other Samsung Apps up to date). This is where the problems first began.
I restored the backup I made when I first got the phone because I didn't remove any of the bloatware. The backup restored without any problems, I started updating apps, getting it back to the way I had it and noticed I didn't have any reception. I tried to make a phone call and it displayed an error "Not registered on network". I thought something went wrong during the restore, so I tried to restore the phone with the more recent backup I had. That, too, gave me the same message. I checked the IMEI number it was displaying 0000000000000/01. Definitely not my IMEI.
I tried my SIM card in another phone and it worked without any problem. I tried my partners SIM card in my phone and it displayed the same 0000000000000/01 IMEI. I downloaded the latest stock firmware for the phone in an attempt to try and get it back to normal, however, even on stock android it displays 0000000000000/01 IMEI.
So I'm in a sticky situation at the moment. Is there any way to recover from this problem?
