Hi guys,I went back from the newest 4.3 update to 1.518 - to discover that I have no mobile service, even the option to chose my mobile network dissapeared. I've also tried to flash 1.534 and it doesn't work too ;/
It also shows that my imei is all zeroes ! ;/
Any suggestions ?

Do you have make a Backup, before?
Try flashing only the baseband from the newer FTF.

Ok I have a solution, but it seems that after going to 4.3 there's no coming back to old firmwares ;/

Well at least for rooting and then updating to a pre-rooted 4.3 ROM using recovery for locked bootloaders

everything was working fine on my xperia zr(c5502) until one day when for the first time the phone had its battery completely exhausted somehow the cellular service was lost and the phone got locked by mcafee internet security and was always asking for the pin at the start.even after entering the correct password it would just get stuck at this part and would never unlock.so i flashed the stock firmware 4.2.2.it was so unstable and was rebooting continously so i flashed the its first stock firmware 4.1.2 which removed the lock and reboot problems but the baseband is now unknown and no imei too and so no cell service and wifi isnt working.i am currently trying to flash the different firmware files and the baseband files of c5502 and c5503 to see if the baseband gets updated.before this problem started,i had never rooted the phone nor unlocked the bootloader or do anything of this sort.somebody please tell me what to do .has anyone xperienced this same error or baseband unknown error for zr???? :crying:

Thats good, first install a custome recovery, do a nandroid backup,,,
additionally backup your efs partition, there are many tools, you could do it in some recoveries aswell...
then flash the your original Stock ROM.
there is another posibility, you damaging one of the IC, responsible for bandwitdh/ network - this means you should replace it. You havent still explained how you lost netwrok in the first place.

Hello
I'm new here and I don't know what can I do to fix my phone, please help!
I have a Z1 C6903 from HK and suddenly during a phone call my phone lost signal and now it can't connect to my carrier network.
I tried a factory reset, upgrading with SUS and flashing original HK ftf but still have the issue.
I also tried flashing different ftf files (.290 , .257 , .534(NUT) , .531 , .681 and .757), sometimes I lost my IMEI but I figured out how to recover it, however, I recovered my IMEI but I still have no signal at all.
Could it be physical damage on my phone?
I hope I can fix it with software.
Any ideas?
I don't know what else can I do
Thank you!
you tried many ways, but did you try another sim card, lol?

Lol, yes I tried another sim card and it doesn't work, I also tried my sim card in other phones and works as a charm!
I noticed that this happened to other people and they fix it with SUS or flashing other ftf, I guess I'm not that lucky
Thanks!
After downgrade via flashtool did you try OTA update? Sometimes it's lose imei when flash older firmware, but after OTA update imei will restore. Hope it can help

Did You try to manually flash each ROM following the release versions, from the oldest to the newest without skipping any build number (else You won't get signal and IMEI)?

That's not needed and the OP says he does have IMEI so that's not the problem anyway

I flashed stock ftf, I'm not flashing a custom ROM.
Do you mean to flash .518, then 5.34 then .257 then .290 and so on to .757?
Thank!
Yes, I do have IMEI but I don't have signal, it's weird!
I had this problem with my old galaxy note 2
The radio chip most likely broken.
Contact sony for warranty if any left!
Sent from my C6906 using XDA Free mobile app
When I insert my sim it shows my a message that says "SIM card could not be read".
Could the problem be the sim card reader ??
Thanks!

Hi, I don't think is the radio chip, because I can see my carrier signal using the app Network Signal Info.
And it seems thta is not SIM locked, no X on the left. I don't know what can be the issue
Sorry to dig up this, but have you figured that out?
Were you to get signal again????
If so, what did you do?
hey did you figure it out? i am having the same problem! though it occured after flashing a custom rom. i noticed lost imei but then i recoverd it. now i have tried almost every ftf and even SUS. imei appears but shows no sim card inserted
Good day, I have a problem with my android and firmware update. I have seen some blogs about xperiaV posting that they already have JB 4.3 update and the latest version of firmware 9.2.a.2.5.. I am wondering how they update it 'cause when i connect my phone to Pc and run the PC Companion, i check the update and it says my phone/tablet is up to date, but the android version of my phone was still 4.1.2 and the firmware version is 9.1.a.1.140.. I don't understand what is the problem of my phone or at my PC Companion Software. I tried also connecting my phone to internet and check for update and still it says my system is up to date. My main concern why i wanted to update my phone, it is because my phone is now dead signal as in no signal (by the way i'm form the Philippines using Smart Communication Network postpaid) I've already switching the network from GSM only and to other choices provided but still no signal. I tried switching my Airplane mode and it displays an airplane icon on the signal area (I think airplane mode is working well, never tried using is). I've read some blogs also that you need to root your phone and flash the firmware and so on to update the android version, but i think its just changing the room, not really updating the system. I don't want to do that 'cause my phone might turn into bootloap 'cause i don't have much knowledge on doing that. I've read also some blogs stating that there is a bug or network issue on version 4.1.2. So i am looking forward from anybody here in the forum who can help or teach me what to do to update my android and firmware version.
I am not sure of it useful to 'upgrade" the phone to solve a problem - this problem of yours. If I were you I'd use the repair my phone option in PC-Companion first, and then see what happens with the phone signal.
You can simly flash any ftf file for your phone with flashtool. Not the sony one. You don't need root access for it
#Mr. Peter-K I've tried it already just a minute ago and still no use. Related to the blogs that i have read regarding on the 4.1.2 version network bug. there problem has been solve after updating the version of there android.
#Mr. Jimmy i'm new here, i hve knowledge on doing flash but i dont have any idea what file to download so that i can update the version of my android to 4.3 and the firmware also. I would like to ask you help if its ok for you,.

Download 9.2.A.2.5 unbranded coming from Singapore or HongKong (since you're from Asia) and follow the instructions to flash.
Good luck

You can jump straight to 9.2.A.2.5
It's important that you wipe all your data... and Flashtool will do it for you automatically if you don't change anything just before flashing
Mr. Istux got an OT question here. I have concern also on my network set up. I want to unlock my network so that i can use other sim card. My phone is Lock to Smart Communication Postpaid. So i wanted it to be open-line. Hope you can give some advise to solve my concern..

I actually don't know how sim-unlocking works.
Have you ever asked to your network? Usually they give you a code after having paid a little fine.

Back to my thread.still my phone signal is not working. i just found out w while ago that if i am in the higher place like 2nd floor of the building, i got a 2g network and my phone signal is working. but if i'm already at the ground floor the signal is not working. is it ok if i am going to do open line on my so that it will receive any type of network or is it really the software problem of my phone causing the signal not working??

then it must be a hardware problem the best thing you can do is get your phone at a sony verified repair store [another thing you could possibly do is a factory reset but it is not recommended since it will delete your phone's data]
