Xperia Z c6603 can't connecto WCDMA after upgrade to 5.1

After I upgrade my phone Xperia Z from Android 5.0 to 5.1, I can not register to WCDMA, only register to GSM. I use the search mode : automatic, it's fail to connect to WCDMA. I use the search mode manual, although we can find and see all WCDMA carriers, I stick my register carrier and connect ,also fail.

 

I use my sim card to input to the other devices, I can use the WCDMA. Please help me this case. How I can fix it ?

Do you have the correct APN settings? How old is the SIM card?

@uliwooly : Surely, I move out the current APN and re-register the new one as the carrier request (100% exactly). But, as i mention, I use my simcard to input to other device ( SS) and I can connect to the WCDMA normally. 

 

As I wrote, I can not register to WCDMA (3G), only register to GSM ( 2G). Obviously, I can use my phone to connect to Internet with slowly connection of 2G.

@uliwooly : I update my xperia Z by OTA, never use the flash way before. My phone has not yet been unlocked.

What if you reinstall the latest update with PCC?

@SophiaW & uliwooly,

 

I repaired already by PCC but issue still be happened, can not connect to WCDMA. My sim card surely can work good and connect to WCDMA by my other devices.

These moderators and xperia support team are replying at first and when they find many people are experiencing the Same problem, they're starting to ignore it!
Even my phone does not register to wcdma networks..
I tried downgrading, using a firmware of different region, even tried cyanogen mod... Still the same!
