Hi, Guys. I recently flashed a new Rom on my T-mobile Xperia Z. However whenever I update to 5.0.2 Lillopop I cannot get cell reception. I live in Guyana so I bought the phone online and had it shipped and unlocked. I have tried both the c66103 and the c6616 however in both , as soon as I update to Lollipop I lose cell reception. All other updates up to Kit Kat 4.4.4 work perfectly. Any advice? I figure it must be something like a baseband problem. I have already tried flashing that however the baseband # does not change. Any advice would be helpful.
Best Regards
sony rom is bugged with callings they said they repair it .
I recently even tried the 5.1.1 update but I still suffer the same problem. I get absolutely no cell reception. It's like the sim is not even being recognized by the phone. I am wondering about trying to build an ftf file however I am not sure if you can edit the baseband in that venture. I believe that it may be the baseband that is presenting the problem, however I am kind of a noob so I need to be sure before I try anything.

Hi Everyone,
Thanks for taking the time to look at my problems
I have a gt-i9000 which was orginally on O2 network. They unlocked for me at the end of my contract but no matter what I did I could not get my phone to accept my new three network sim.
Three replaced the first sim and I know the new one works - they got it to work in store and I've used it on an old handset of my dads.
I can get my works sim to work in the phone and connect to data with no problems.
It was suggested that I try flashing the phone with new firmware.
So I have managed over this weekend to upgrade my firmware to 2.3.6 gingerbread xxjw4
then root the phone - first attempt bootlooped it.
but second attempt worked.
I've now got it upgraded to
4.2.2
baseband : i9000XXJVT
kernel: 3.0.71- Semaphore_JB_2.9.18s
slim version : slim-4.2.2.build3-OFFICIAL
build number JDQ39
but the three sim still will not work in the phone.
So my questions are :
any other suggestions on getting the sim to work or could it be an actual fault with the handset?
I have my husbands gt-i9000 I could try and root to see if that works but that is still sim-locked to o2 and I don't know how to remove it.
I'm also considering downgrading the firmware as I am finding quite a few of my everyday apps won't run. And my data on o2 sim seems quite flakey if it connects.
Is this as simple as flashing the old firmware back on?
Thanks for your time - grateful newbie.

Hello to everyone!
This is my first post to this great forum. Recently I bought a Sony SP C5303 and now I face a complicated problem and I want your help.
The situation:
The phone was bought as unlocked (and not rooted) and when I got it, it prompt me to update to the 4.1.2 12.0.A.2.254 as previously had an older build version. I successfully did the update and everything works fine BUT right now I am wondering why I can't see the official update for 4.3
After a lot of search I realised that the phone was supplied from T-mobile (UK) as it has customization version 1272-7168_R6A
So, the phone is unlocked, unrooted and since I bought it operates on Three network.
However either when I connect it with PC companion, or I do the manual search for updates through the headset, I am unable to see the update to 4.3
I am wondering if there is any conflict between the T-mobile unlock and the Three network that I operate the phone.
Is there any way so I can trigger the update? Should I wait a little bit more? I am not sure and I am not so good with these things.
The only I want is not to cause the phone to lock somehow or to install a custom rom, neither root it.
Thank you very much for your help and your answers!
I would stay on 4.1.2. 4.3 is a piece of crap. I made the mistake of upgrading and had to downgrade. I tired many roms and did not like any of them. Stock, root and xposed frameworks still best for stability, features and battery life.

This is due to the mobile operator themselves. I am with o2 and do not have the 4.3 update for my SP either, it is down to the operator to decide when they release the update as they have to fill it with their bloatware first!
You can of course flash 4.3 yourself using flashtool I did, their are plenty of guides on this forum

To be honest I am a little bit confused what determines if the phone is going to update or not.
I mean that is the provider responsible for delivering the update or the customization version? If we think that with no sim, we just plug the phone to pc companion and it is able to see the update, then it depends on customization version.
Is there any official reference for how the phone is determined to be valid for the update?
I still believe that there is a conflict here between the current provider I operate the phone (Three) and the customization version that comes from T-mobile (the phone was unlocked from T-mobile).
Thanks guys!
P.S @xEaGLeNeC Wow!!I heard completely the opposite from many people. They claimed that the phone battery last more with 4.3! I will try to search more if it finally worth to update or not.
Hi everyone.
I'm a bit stuck here, and I have googled quite a bit, but seem to come across conflicting information.
Basically I bought a PAYG S3 LTE on EE UK that had official status, and wanted to unlock it to the 3 network. The only way I found to do it for free was to downgrade the ROM to 4.1.1 and use the hidden menu hack and so just decided to take it to the local phone shop and let someone do it properly.
But when I got it back, it turns out that he actually did the 4.1.1 hack himself and has rendered the phone 'modified'. I was a bit miffed as I wanted to keep it on 4.3 and get OTA updates.
So my question is, can I flash a stock 4.3 ROM back to the phone, and if so, will it keep the network unlocked for my 3 sim? Also, will I be able to root 4.3?
I do apologise if these are pretty obvious questions, but like I say, I just have seen many people saying different things.
I've also flashed a few phones of my own, so I'm not a complete newb in that respect.
Any info will be much appreciated.
Cheers.
Download your corresponding 4.3 firmware from: http://sammobile.com/firmwares/
And just flash it with Odin
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,.

Look at this: http://forum.xda-developers.com/showthread.php?t=2648320
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

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??
Hey guys,
I just bought a Z3 Compact (D5803) for my girlfriend on eBay. It said the condition was new (other). I set up the device, and it was running 4.4.4 Kit Kat. Everything was fine and normal. I just plugged it in and updated the phone to Lollipop, and now when I boot it up there is a docomo screen, and in the settings there is a new section for docomo. All I did was update the phone through the Sony Xperia Companion program on Windows 10. Is this something I can get rid of? Or do I have to unlock the bootloader and flash a non-docomo ROM? I would hope there is a way to get rid of the docomo stuff, but I guess that's probably not possible?
Thanks.
EDIT:
I fixed it. I found the thread with all of the firmware, and I flashed the FTF for the USA 6.0.1. Now everything is great, no more Docomo!

I know you've fixed the issue so I don't really need to say anything but I thought I would anyway.
DoCoMo's a Japanese provider if I remember correctly. I'm guessing that the phone was originally from Japan so Companion just put the latest Japanese rom on. As long as it still works with your network, that shouldn't be a problem. Boot animations and settings in..er..Settings can always be changed.

Thank you for the response. The story has gotten a bit complicated for me haha. When I put the newest firmware, NFC stopped working completely on the phone. It said the NFC firmware couldn't update. Apparently if you run firmware that is different than the DoCoMo firmware, NFC breaks. But the weird thing is, the DoCoMo variant has a different model number, and has the DoCoMo logo all over the back. Mine is supposed to be the D5803 and doesn't have the logo on the back. So now I'm trying to talk to Sony and the eBay seller to see what's going on with that. Not sure if you have any idea about that. I wonder if it was the DoCoMo variant and the eBay seller just replaced the back cover or something.
