I cann't make a phone call "call ended".

[akram_1000]

My xperia x8 stop making calls, when I make a call the phone ends it and say "call ended". But I receive calls normaly. I compared my x8 with another xperia neo, I found that Mobile Network State is disconnected I found this from Settings> About phone> Status. It should be connected as in xperia neo. the signal is good. I replaced the SIM card with another company SIM but no changes. I call the customer services they told me to call 123, their customer services number, if you can and I couldn't make the call then they said you have to go to technicians to install new software.

Try to change the network mode under settings > wireless and network > mobile network > network mode. Set to only GSM and only WCDMA and try again. Restart the phone after you have changed network mode. 

If you don't experience any difference I suggest that you repair the phone software using PC Companion: 

http://www.sonymobile.com/update

In PC Companion, press start on Support Zone > Start on Update the phones software > "Repair phone".

I've tried solution 1 but no changes.

Solution 2 I've tried before and I've just tried again with the PC Companion I downloaded from the link you typed but the same problem occured again, which is after I press at reperpare update and downloading the software to the PC, which is step 2, and come to step 3 which is to update the phone by unplugging the USB then turn off the phone for five seconds then plog with holding back button starting step 3, I get an alert message. and that message is " Download error: Unable to download your phone / tablet software. Please check your internet connection to try again later" I press retry button but no changes.

You could try with Update Service instead:

If you get similar error messages in Update Service I would suggest that you try on another PC or when connected to another Internet connection.

Nothing happened . . In Update Service, when I connect the phone with hold pressing the back key after I turned it off, I get this alert message in window of Connecting your phone: The current software on your phone will be checked "Failed to detect product:The product could not be identified> P lease disconnect ot and try again".

In the xperia neo's PC Compaian, I couldn't even download the software to the PC. step 2.

Changing the internet connection, I cann't do it right now.

Help.

So . . What about CyanogreMode?

[Sreelatha]

It is the phone software that is malfunctioning. If you go into your settings >Apps > ALL then you have to patiently tap on each app and erase the cache and data, don't erase data on your email, contacts. You have to erase data, cache on all other apps. Then your problem gets fixed. Other than that there is no problem with network or the phone.
