Hi guys, please I need some help with my xperia z, it presently does not get any network regardless of changing sim. Dis occurred few days after upgrading to newest firmware .67. It worked fine after some days but signal started gettin poorer.realised dat after givin the phone a little bump it comes back to full signal.eventually it stopped getting network altogether, except in rare cases when I feel I'm close to a tower , it searches but cannot register on the network sayin to ensure that a network signal is in range 99asu.I also cannot switch to manual select of network. Please anybody with a solution. Want to know if its a hardware or software problem. I don't have a sony service centre here that can help me.thanks
I had a similar issue and found that my "APN" was missing (Telcel Mexico). I created a new APN from information on the Internet and all is well.

What model do you have??
You upgraded by PC Companion or by flashtool?? Maybe the baseband is incorrect and the phone don't have signal, maybe your carrier use two band and not both are in all coverage.

Initially upgraded to .434 using flashtool, then .67 by OTA. By baseband do u mean 2g and 3g? Cos I don't get any form of signal at all.
Hi there, I have had the same problem: after updating the XZ to 4.2.2 (2.67 over OTA) the signal dropped instantly. Therefore I had to send it back Sony Care. They fixed it. The update has overwritten a different smallband/baseband-version above the other one, just as I suspected. I bet you can flash it yourself (your an XDA user..) instead of waiting 2 weeks or more. If you don't know how it works and you've absolutely no experience with flashing, just send it back to Sony care.
I think the easiest way is to flash a different (older) baseband-version on your XZ, reboot/factory reset and see if it works. The second method is to try downgrading the software to .244 INCLUDING the baseband-version, then update it by flashing the XZ to 2.67 while EXCLUDING the baseband-version. The third option is to re-flash (with flashtool) the 2.67 update but a different version (GLOBAL).
My phone details:
Modelnumber: C6603
Android-version: 4.2.2
Smallbandversion: 9x15A-ACEFWMAZQ-30110068-44
Kernelversion: 3.4.0g43a9ba9
Buildnumber: 10.3.1.A.2.67
Altough your smallband/baseband may differ from mine. Therefore, please find your own software-version. I'm using:
GLOBAL-LTE_10.3.1.A.2.67 (Netherlands)
Goodluck! Please let us know about your issue:fingers-crossed:.

But what Xperia Z model do you have?? C6603, C6602, C6606??
I have a similar situation in the case of C6603, in my carrier sometimes I have 2G signal but never 3G and other times no signal. In the case of OTA or PC Companion updates, sometimes upgrade to diferent model or carrier, I have a friend that upgrade his Xperia Arc by PC Companion but with the uncarrier firmware. Maybe this is your case, the OTA firmware don't well upgrade your base band.
In this case I suppose that you can flash only the baseband by Flashtool, but be carreful that the firmware was made for your Xperia Z (C6603, C6602, C6606).

Look this: C6602 10.3.1.A.2.67 STOCK
If you have doubts and I can help you tell me.
To find your version, just dial *#*#7378423#*#* => service info => software info => File system version: ......; download it from Xda and (re-)flash it. I've read about this; it happens a lot with XZ's with the GLOBAL firmware. You've probably the same version. Good luck and please let us know

Try to flash full firmware, because you don't have signal at all, maybe could be hardware issue. Cultural question, You try your sim card in another phone, don't you?
Okay I eventually found out what the problem was.it's a hardware problem, connection of the antenna near the vibrator, bottom right when lookin at back of phone was loose.thanks to all who posted suggestions.eventually opened it myself.
Hello, I`m new here. I got xperia sp c5303, android 4.3, build nr 12.1.A.1.201. The phone is almost one month old, I`m from Romania and I bought it from Emag.

My phone was running smooth before the update to 4.3,now it`s just laggy.
Please guide me if you can since I`m noob and have no ideea what I`m suppose to do.

Hey everyone,
I need help soon as possible.
I have a Xperia Z1 C6903 with android 5.1.1 and my firmware is 14.6.A.9.368 and I want to downgrade to 4.4 (KitKat) because Android 5.1.1 is stealing a lot of battery and is slower than 4.4, so I want to get back to it.
MY PHONE IS ROOTED.
I saw a lot of threads about this, but I still don't know much..
I have flashtool, I just need a download link for a firmware of 4.4 (KitKat) that is compatible with my phone and will run without problems.
(I dont know if this is important but my SI is 1276-1925.8 EL,EN) <- Don't know what is this..
I'm from Portugal, so I'm sure I need a firmware of Portugal version I dont know.. I think I have an Unlocked phone.
Waiting for help.. Thanks!
Wrong board - this should have been under XPERIA Z1 Q&A, HELP & TROUBLESHOOTING
No, you don't need to unlock your phone's bootloader to use Flashtool and flash a stock 4.4.4
You can check the FTF download links posted in our community boards. Technically speaking it's OK to use another regions FTF on your phone, i.e. Philippine phone (like mine) using Singapore ROM is just as the same as Philippine phone using Philippine ROM.
I recently downgraded to 4.4.4 from a spanish mod'er.
Was also just sick of LL's battery life... and suddenly I can forget about charging etc. Finally lasts for about two days again...

Lollipop is faster and much better overall
Kitkat just fur battery life on 3g and app compatibility
I find if i disable location the battery last longer

Hi,
So i bought my xperia z3 compact online about a year ago.
Finally bothered to look at the technical details of my devices software and have found it's running the Taiwan software.
I was wondering if it was safe/a good idea to change to the australian software?
and if so, how would i go about it?
Thanks in advance peeps!
download the australian FTF, and flash it with flashtool
Hello. I killed my D5803 (living in Germany) and I can get a 5833. Next to the different basebands of 5833 - are there other important differences?
I would also going to install Android 8.1. on the 5833. But do I need to consider then anything for rooting, and flashing (e.g. using other ROM)? Or is it all the same? For some ROM the developers have described that ROM is for 5833 and 5803. Is this correct for all ROMs?
And does anybody know about 5833 in Germany? Any problems with LTE?
(Before anybody complains if this question was already ask from anybody somewhere - I tried to search for it)
Greetings Odiad
