1)      My Xperia ZL turns itself offwhenever it decides.After that most of the times I have problems when trying to turn it back on. Sony Logo Appears and it turns off again.

2)      Suddenly Dropping Networksignal then it appears as Red Cross [X] NO NETWORK AVAILABLEeven after I replaced the sim and tried with another provider.

Its prefered LTE /  wcdma (umts). If I put GSM only the same result

In this case it may be worth trying a firmware repair to at least rule out a software issue:

1. Download the PC Companion software from http://www.sonymobile.com/gb/tools/pc-companion/
and install it on your PC.
2. Install and open PC Companion then select Support Zone.
3. Phone Software Update.
4. Start.
5. Repair Phone
6. Continue
7. Accept data removal
8. Next
9. Wait for prepare
10. Select Phone
11. Follow the connection steps

I have solved my problem 

I have given my sony ZL to sony service centre and they replace the battery and now every thing works good.

I have the same issue, right after the new update. I have to download T-mobile "Internet and Data" Setting everytime i need to get online, has the "Reparing" worked? There is also another problem, everytime I leave the DATA on, phone restarts on its own if there is no activity. This (restart) problem occured before the 10.5.1.A.0.283 update and still happens when I have DATA connection on after downloading T-Mobile setting.

I tried to use the PCC the other day, it took too long, so will try again, just want to make sure if the "Repair" fixes this stupid bugs 

Any assistance will be greatly appriciated!

Thanks,

Having the same issue. Does the Repair Phone from PCC works?

It keeps disconnecting from network when I open any app and try to read data. Yet sometimes Gmail works not so fine. I keep seeing the message "Change network operating mode" under Network Mode in Mobile Networks.

I had the same issue with T-Moble. Try changing APN protoco from IPv6 to IPv4. It worked for me (I found the solution on the XDA forum).
