[Q] Xperia Z won't answer calls - Xperia Z Q&A, Help & Troubleshooting

Hi! I'm new to this forum.
I'm working as an IT manager, and have a user who has a Xperia Z. He have had problems with it since day one. The phone often does not respond when there is an incoming call, even when he uses BT handsfree and Sony SmartWatch 2.
The phone have been to service several times, replacing the screen one time, and charger port another time (the service company claimed it was broken), but I'm unsure if that means replacing the motherboard as well. We have even recplaced the sim card and tried with a twin sim card and the main card in another Z. We also tried backing up the phone and restored the settings onto another Xperia Z, and that one had no problems what so ever. We also tried backing up the other phone and restoring onto the phone with the problem, and the problem was still there.
Model number C6603
Android Version: 4.3
Baseband version: 9x15A-ACEFWMAZQ-30110082-51
Kernel version 3.4.0-g1b44cd5
Build number
10.4.B.0.569
Can anyone help?
Thanks in advance!

well it seems like the phone is indeed faulty and would need to replaced as whole... sorry for the trouble mate but you have tried everything at hand...

I was afraid of that... But thanks alot for the answer! Now I just hope that the service company agrees with us

[Q] Flashing over a dev-rom

I managed to get hold of a pre-production Xperia T with a non-production ROM on it, it was pretty rubbish so in my haste I decided to flash the O2 branded stock rom over the top of it but now unfortunately the phone functionality no longer seems to want to work, also there is no IMEI either or other relevant information and it doesn't recognise the SIM in it anymore.
I'm wondering if i've totally fluffed this? As a bit of a noob (hence the name) I didn't backup the rom that was on it or anything, and i've just written over the top but now the device is no longer functioning as a phone (although everything else functions fine).
Is it a possibility that this is protection put in place by Sony to stop people getting their hands on prototypes or is it simply that i've missed something out / done it wrong? When i tried to restore the phone in Sony Companion it told me I wasn't allowed to restore a brown phone from my IP address, making me think this could actually be because it's running on some older / different hardware but the fact now that I have no IMEI, no working radio on it makes me think i've bricked it as a phone.
Is this a common thing / has anyone seen this before / have i just created a very expensive paperweight?
Any help you could provide would be invaluable
Thanks
More googling has told me a brown phone is basically a developer phone, as such if i flash a retail ROM on it have i ruined it as a phone? thanks to my impetuousness i didn't save the old rom either
well you can try to go to the sony service center for them to repair.

[Q] calls over 3G - not stable

Hi,
I just bought my Xperia T in Romania.
Operator: Orange
The software version was 4.0.4 Central Europe.
When the phone is on 3G network , even if it shows full signal, the calls do not go through.
I have to wait few minutes or restart phone!
Sometimes is works, sometimes it does not.
Also who is calling me says that the my phone is disconnected.
This does not happen on 2G network.
What is the problem?
Operator related or should I take it to warranty?
I changed from HTC Desire and did not have this problem.
Also I tried the JB update and the same problem
Take it back to the shop, I never had that problem with any rom.

Enviado desde mi móvil.
damn it !
I was hoping that someone else had this problem and maybe related to radio version (used with my previous Desire).
But I see that there are no radio versions for Sony. Just baseband which I understand is embedded in ROM.
Oh well... two more weeks with my broken screen Desire till I will get this one back
So, after two frustrating weeks and sending the device to service and getting a response "defect not confirmed,
I went to the service explained them and FINALLY they understood
They replaced the motherboard in half hour and left happy from the service center.
BUT, as I was in the car discovered that there was no google apps, no way to input google account, etc. and the software version was the first one for LT30p.
As I did not want to go back I got home and hoped that a PC Companion update will solve the issue.
But surprise, it said that there is no update
So I installed the JB FTF and the 3G problems again
I also tried more Stock FTF and the same problem
So my question: might there be a problem that the FTF I have been using are for LT30a (which is for 4G)
Is this possible?
I even tried unlocking the bootloader and EMMA only shows .195
Any ideas because I don't want to get it back to the service.
I am starting to think that this might be a LT30p vs LT30a software.
Does anyone know how I could see what are the official firmwares for my phone?!
Is there a way to get my hand on a user/password for EMMA ?
Thanks
You are telling us that you are using a firmware which is designed for LT30a on a LT30p?
The baseband is different for sure.
You can flash JB version for LT30p with FlashTool.
Im using the same LT30p on orange ro and had no problems.
No
I was just wondering if maybe there is Sony issue because if i go to sony support website it only shows Xperia T (LT30a).
Maybe there is a problem with how I upgraded to JB.
Regards
I think I am seeing the same issue too now with my xperia V on JB stock.
Phone has connectivity but calls and sms are not getting through when it's on standby. It's fine immediately after I wake the phone up.

[Q] Weird troubles [SOLVED]

Hi,
I'm using the standard rom for my xperia Z, actually in, official .253 firmware.
I've tried to test the NFC wirth 2 friends, on has a Xperia Z like me in 4.2, the other a Galaxy S4, that doesn't worked for any of us, just nothing happens when we try to exchange a picture with the NFC.
Also if i enable the NFC i loose my network connection, even if i reboot the phone i do'nt know how to have back my network except to reboot many times the phone.
I've reinstalled many time completely the phone with PC compagnion => same problem
I've already changed 2 times my sim card because of similar problem.
Any idea?
Ok i've identified the problem, that has completely deleted my APN...

Xperia V signal antenna problems

Hi
I have problem with signal antenna since 2 weeks ago on my xperia v, I lose my signal antenna randomly, rebooting sometimes help but it is very annoying because I always missing important calls... I googled it and according this threads form sony mobile help center get this result at last: It seems the Xperia V JB 4.1.2 firmware find a new bug for signal antenna. Now, is there any one have the same problem here? I didn't solve my problem yet but I think we can talk about that and find out a ceaseless solution. Please let me know your experience and idea about this problem...
Thank you
i don't know for sure if my problem is related to your's but it's similar i think..
well my one sometimes can't get signal for some while after boot some times..
more frequently it says that the sim card is missing despite showing carrier name and proper signal sign..
i always have my problem solved just by entering airplane mode and out so it could reconnect to network.
It can be firmware bug too. airplane mode sometimes works for me but I have to reboot most of time. another experience or idea?
No idea or experience?

I know the post is old and others, but now I just got a V xperia LT25i.
In which I have had the problem of the radio signal, and it was as easy as that the signal cable inner radius, had broken [incomprehensible], since neither has shock or anything, and it was something sudden, as it has I been running well for a long time, in the hands of someone else ..
So anyone who may have this problem, remove the cover [are 6 or 7 screws], and on the right side check that the cable is good, and if change is broken, and if it's okay, then the problem is Software , rather than hardware ..
Thanks for your effort.

[Q] C6903 weird SIM / network error (with really bad timing)

Hi you all! Please help a girl in trouble!
Some time ago I flashed 3SE rom (1276-2189_14.5.A.0.242_R1D) on my phone because ..well.. the Nordic combined lollipop update took ages and I didn't wanna wait no longer.
The flashing went well and the phone worked properly. About one month ago the usb-cover came off so I sent it to get repaired.
Yesterday I finally got my phone back after three weeks and was such a happy girl. I flashed the customized NCB (1276-9897 14.5.A.0.270_R1D) to get rid of the 3-logo when booting. Then I moved all my photos n stuff on the phone... and first after this I inserted the SIM-card - only to notice that the phone does not work.
It won't connect to network. Says stuff like "invalid card", "emergency calls only". Everything else seems to be OK. I have tried a couple of SIM-cards that work in other phones, but nothing. The cards are not home cut, they are original micro sims. I took the sim lock off also, but it does not help.
I have tried flashing several roms, but still the same. I noticed that on some it get's some kind of signal strength, but on some roms it's just 0. I've flashed with flashtool and used also Sony PC Companion. But still the problem remains.
The IMEI can still be seen. On the phones package is the text SI 1276-2949.11 (FI, DA, IS, SV, NO). The phone is less than one year old.
Before everything got wrong the bootloader was unlocked. I checked with Flashtool to unlock bootloader and it showed the IMEI and redirected me to Sony's site, but I got a bit scared if some quarantee would get void. I don't remember the BLU redirecting me before to Sony's site if I have fiddled around with the phone and Flashtool..? The phone is unrooted and I would want to keep it that way. [Edit: it says "Rooting status: Bootloader unlock allowed: Yes"]
Now I am only very confused, and very stuck.
One thing that makes this crappier is that I am leaving tomorrow for my vacation, a trip that will last over one month... I really need my Xperia Z1 working and with me (and I really should be packing etc. instead of googleing and trying to figure out wtf I've done this time.... Unfortunately I really need that phone with me ).
Can somebody help, does anyone have any ideas?
And of course I have also tried the SIM cards with some paper behind them so that they would fit tighter.
If I try to put the APN manually it says that "Access Point Name settings are not available for this user".
I just tried once again to fix the phone with PC Companion, no luck.

Hello!
I can't find much to do but try to downgrade to a previous working version that was on your phone, and completely wipe everything (with stuff backed up of course) and see if the sim works, then update using PCC.
That's all I can think of, good luck and have a nice trip!

Hi and Thanks for the hints!
The 3-version of Lollipop worked earlier, but not anymore. Unfortunately I think it is the only version I can find from those that has worked on the phone earlier. Can't seem to find the original anywhere. I have had some backups of the phones and firmwares, but my computers got messed up, so I've lost some of the roms (and of course I have tons of other stooopid backups and their backups )
I'm trying to downgrade to some 14.3. global thingie right now, but my hopes aren't too high since I've done this already few times.
And thanks! I am sure that one busted phone can't mess up my vacation even if it makes it much complicated (water resistant, good camera, gps and battery etc.) But hey, what the heck, it's summer and I'm off duty

At least they are proper phones that actually DO work.
It's a shame I don't have any of those good ones left.
No other ideas whatsoever? Anybody? Mumbo jumbo voodoo? Rain dance?
Can you see your imei in the service menu?
Yes, the IMEI is there.
Got it fixed in another country in three days!
The service company I used first had broken some chip on the phone... Won't be using their "services" anymore.

Glad you got it fixed.
So it was a broken chip? Or did the chip get damaged when the first company tried to fix this issue?
