Same problem here. I got my update through PC Companion just now and now phone won't connect to my home network. It is Generic and unlocked to all networks. I have issued this SIM card just for this phone from my service provider because old one was miniSIM. And it worked well before update. I tried reinserting card, it does recognize SIM, it does find my network, it just refuses to connect to it.
Any thoughts?
Then downgrade back to 4.3 using the 4.3 ftf file accordingly via flashtool
Fix
Just flash baseband from 4.3 and everything is back to normal i fix it that way.
Ok, thanks for possible solution. However, I replaced my SIM card with card from another carrier. It is prepaid card so it is inexpensive to buy a new one. Cards from two different carriers are visually identical, but old one does not work, while new one does. I like new number (starting with 666 ) so I will stick with the new card.

Download 4.3 ftf for xperia m2 (check your proper version in settings) and download flashtool ( google it ) and when you open the app you choose flash mode and choose the 4.3 ftf but uncheck everything on the side excepted baseband and voala when you boot it works. To enter in flash mode you restart your phone and hold the volume down key and connect usb in same time. you have tutorials on youtube you can check. hit thanks if i helped
Hey guys, this is the first time posting here and I hope my problem will be solved.
Yesterday, I was flashing a bad rom in my Sony Xperia C2305 that didn't work. I'd backup so went to Cwm and recovered my stock rom but after recovery SIM cards were not working, after searching a lot I came to know that baseband version and IMEI were messed up by bad rom and they both are showing unknown till now.
After searching the whole day, I came to know that it can be fixed by flashing ftf firmware so I download both latest and old firmware. But I couldn't flash those firmware with flashtool because of CWM recovery.
So, I tried to remove CWM and get back to stock recovery and I came to know that only odin can do that but there is another problem with odin. It simply needs pda, csc, phone files which I can't even check by dialing *1234# because of SIM error.
Now, if someone can help me to get pda, csc, phone file I can proceed, other than this, I have extracted the ftf file and found recovery-sign.sin file, if somehow it can be converted to img than I can recover my stock recovery with mobile uncle app.
I also tried to write imei with mtk droid tools but it didn't work and not even writing imei with terminal worked.
Except this all, I have also brought volcano box from my friend which can also be useful, I'm checking it out now
Please anyone who knows the solution for my problem please guide me to fix my phone and yes it has still 8 months of warranty but it's rooted might not work.

The only hope you will find here is flashing a stock package as touching the IMEI in any way is illegal and banned here.
Sorry, I didn't know that touching IMEI is banned here so regards flashing, is it possible to flash ftf firmware with CWM, if yes than how?

Hello guys.
I have a xperia Z3 from VIVO and flashed a rom from OI, everything went well on flashing the rom but after it finished i noticed that i lost my 4G. When i search for network there have a TIM BRASIL LTE but it won't let me register on it.
Do anyone know how to solve that?
Thanks!
Input the correct apn settings from your carrier

Lito, do you think that would help?
Because the problem is that I am not able to register to the LTE network, it's not related to the ability of using internet.
Actually, this is exactly what happens, after i flash the firmware i have 4G but after a few minutes (Between 5 and 10 minutes) i completelly lose connection to the LTE network, even if it's available in the networks list.

(UK firmware for example)

Maybe if you explained a bit better that would?
Like mentioned before this post, try to flash only the baseband from another region, hopefully that will solve it.

Lito, thanks for the sugestion, i flashed the baseband for the Customized PT and after flash i got the 4G signal for about 30 minutes, but when i rebooted the phone, i completelly lost 4G again, and now in the network lists there is no LTE from TIM. Could it be because i installed an european baseband on a mobile here in brazil?
Thanks agian.

thats weird... are you sure you have the correct APN settings inputted? Also, i would assume youve tried flashing the VIVO's baseband or any other USA roms?
Try the following if you have already done all those: go to dial pad and input *#*#4636#*#* > phone info > menu top right > select radio band > try Australia or USA or what ever pops up > scroll down and make sure LTE/GSM auto is selected or try out the other ones > scroll back up and hit the "run ping test"
if all these doesnt work, i would advise you to go back to the original rom.
just curious, which model number is your Z3?

Lito, now i will complicate a little bit more then. First, the model number of my mobile is D6646 from Brazil with DTV.
Also, i tried to flash the Vivo Baseband and it was worse, i did not install any baseband from USA, just from Portugal.
I tried that on the keyboard, but when i chose USA band i just can't even register on any TIM network.
Also, i tried to flash the original rom, but i can't flash any other firmware apart from Oi. I get a blank error line on flashtool for every other rom i tried to install, so it's even worse
Feel the challenge.
Thanks again for all your help.
flash back to the original ROM if you can, also, how did you flash to the new rom? through recovery or Flashtool? if you see a blank space or what ever, you might not have the correct drivers installed on your computer, especially if youre running Windows 8.
that being said, i dont see D6646 in Xperifirm, i cant tell you what to flash and what not to flash. Without that, i wouldnt advise you to flash anything but the original rom that it came with, you dont want to soft/hard brick the device.

Lito, I tryied to flash the original room, I am using XperiaFirm to download the firmware and flashtool to flash. I can flash the Oi room, but i can't flash the vivo BR, the Claro Argentina, or the Customized PT, all of them results in a blank error, it's not drivers problems, since i can install the Oi firmware and also i disabled the signature on windows in order to install.
Anyway, i solved the problem in order to show another problem. Here is the situation:
I created another APN to use when i don't want to use internet because even with data package disabled my mobile send data to the carrier that charges me, when i deleted that APN the 4G worked perfectly, but now my carrier is charging me the data . Any idea how to block this data comsumption?
Thanks again.

that is extremely weird, never had such issues with any of my android phones. make sure data roaming is not on, the carrier shouldnt be able to charge you if you disabled data
Also, make sure the FTF files youve made with xperifirm and flashtool are correct, like not including the TA files etc..., i would advise you redownload those FTF files and try again, also make sure you have the latest flashtool available.
at this point, you are probably better seeking for a developer or someone who can read codes, make a logcat and see if the flashtool thread is available and ask there. Aside from the FTF files, you are better off asking the carrier why they are still able to charge you in such way. Sorry man, this is as far I can aid you in this matter. GL bud!
I send my unlocked and rooted Z3 to the sony repair center. They sent it back unrooted and updated to the latest bell firmware, I didn't check if my SIM worked or not at this point as I had a nandroid backup that I made before sending it in in case they decided to reset everything.
Steps:
Used flashtool to downgrade.
- downgraded phone with D6603_23.0.A.2.93 ftf on the XDA thread, first time bootloop due to drivers I think, reinstalled drivers and second time worked fine.
- ran giofroot exploit. used v3.1
- mounted /system rw with ES Explorer.
- installed Z3 Dualrecovery for locked BL.
Tried to restore my nandroid backup through recovery, system restored ok but got error 255 when restoring data. Bootloops when I tried to turn it on.
Flashed a clean build prerooted 23.4.A.1.232
This is where I noticed the SIM gets an invalid card message. Checked service menu for sim lock
it reads [ ] network 0 so it seems to me like SIM lock is not the problem.
At this point I tried downgrading using flashtool again to start from the beginning but it hasn't worked. Googled this problem but there was no definitive solution in any posts that I have encountered.
Anyone have a clue on what to do? Should I try to update firmware with PC companion and hope it fixes it?

I tried to put in a sim card from the original carrier however that did not work either. Anyone have any ideas what I should do? Phone IS detectable in flash mode, are there some options I can try?

So assuming something got messed up while restoring backup, it should be able to be remedied by flashing, correct?
Yeah, flash a FTF and wipe appslog and cache and boot without doing anything and see if SIM works

If anyone finds this thread later in search, I figured out why this happened to me.
When the repair center sent back my phone, it re-sim locked my phone, I needed to put in my simcard to get the sim unlock prompt and enter my unlock code again before I started downgrading firmware and rooting etc.
I ended up sending it back to repair center and they reset the firmware back to normal - I assume they have more robust repair tools than I do. Thanks everyone for the help.
Hi.
My Xperia Z3V (D6708) has a problem to get a network signal.
Originally it works with SIM card but after i flash using a Flashtool with lower version, it does not gone with normal process.
Right after flashing ROM file, it does not process in the fota blah file so i tried to install ROM file with upgraded Flashtool and flashed successfully.
All Rom files copied to my phone normally but i can not attach my phone to network with a NETWORK ACCESS RESTRICTED sign. This sign always turns on notifications. Flashed other version of original rom files but i can see the signs with no network signal. Any different roms have same problem.
SIM card works with other phone and IMEI numbers are all alright.
I think this problem definitely comes from Flashtool with lower version.
How can i solve this problem? If i need i can use QPST, QXDM for changing NV values.
