Sent phone to Sony repair and now it won't update

[nurav666]

I have a ZL C6506 and it's battery went out. So I sent the phone to Sony for repair. They replaced the battery and flashed the phone with an older software 4.2.2 version 10.31.A.0.244.
Now the problem is that when I go to "Update center" and search for updates, it says the phone is up to date. I know that's not true since my phone had been running 4.3 before dying.
I can't understand why my phone won't update. Does anyone have any suggestions as to how I can force my phone to update? I tried through PC Companion but no dice. It says the phone is up to date too.

Please help!

Can you post your build.prop in /system/ ? Not sure if its possible without root. With adb it is simple, just use adb pull /system/build.prop.

Download any stock firmware in .ftf format from the forums and use flashtool (http://www.flashtool.net/download.php) to flash it to your phone.
Flashtool doesn't care if your device is up to date or not. It just writes the content of .ftf files to the right partitions on the device. :good:

If you want to check if repair service destroyed your Xperia, do not flash the newest stock firmware. Download an older one. After flashing the older firmware,
try to update via PC Companion. It should work now. If not, send it back to Sony and tell them they bricked your device.

May be they replaced your handset with a prototype

I also faced this similar issue. I bought a second ZL (c6506) last week that came with 4.2.2 (10.3.1.A.2.67) and I don't see any update on PC companion or SEUS. It looks like 4.3 update has been pulled for some reason here in the US.

I'll post my build.prop later this evening.

Ended up using flashtool with a FTF to update to 4.3. It erased all my data but oh well, I redownloaded everything and now I have 4.3. I just hope I'll be able to update to 4.4 OTA or through PCC when it comes out.
