If you still got error on installing the applications,try to reset the phone. Go to settings > Master reset and choose if you want to reset only the settings or the entire phone,if ask for a code,the default will be 0000,but if you change the code before,enter your desire code and after that the phone will restart and it will go back to its original settings.


Good luck...

I advise you contact Sony Ericson because of the risk involved in unlocking phone.

Hello raaj,
If the navigational stick on your sony ericsson k800i is no longer working, the problem simply is that the link at the bottom of the stick is broken, and is no longer pressing the keypan anymore.
The solution is to have the phone disassembled and replace the joystick.
Would be glad to know if this information was helpful toy you. All the best. Elect_Comp

dont worry because it is a common problem with this set as i was facing it too . u just need replace the keypad cover and everything will go fine.

"Accept calls"
select "None" to block all calls or select "Only from list" to receive selected calls.
For "Only from list" you have select "Edit" from the right button which will show you "Accepted list" in which you can add selected callers.

Hi, One of the reasons why this message appear is the phone does not accept any other simcard because it is lock to a particular service provider,if you want to use any other sim provider prior to you country,the phone needs to be unlock all network provider,and this may possible by bring the phone to any mobile service shops near you for the unlocking service. Another reason of this case is the improper updating of phone firmware,might luck something on the procedure, we have a technical term distinguishing this type of problem,usually when we flash or update a phone using a gsmgadget and we miss some settings to generate,we encounter this problem. To make everything clear about this matter,better ask assistance to a mobile service center and the will fix this problem. Thank you for visiting FixYa....

My sim has blocked i cant find the PUK code what will I do to unblock my sim i need a PUK code for tm sim

Well if you are tied to a particular network all you have to do is to unlock your phone to use it any other GSM network. You can get the unlock code through online. Give your IMEI number & get the unlock code for ur mobile .............You also get through online..........I will suggest the website Unlock-Zone.com which is doing good service .....you can approach this website.

Basically, if the phone does not power, you need to check the status of your battery and charger,also check if the power switch is bouncing,if does not gets back or bouncing, need a replacement indeed.

* By clicking ON the phone,see if there's a red light blinking beside the camera switch.

There are 2 causes of Red blink.

1st, Red blink may cause battery problem,might be lack of supply or drain due to long term used and can't able to power it up. Try to replace another one for a test before buying a new one, to see if only battery is the problem.

2nd, Phone software might be corrupted or damage, base on my costumers cases, many phone encounter full memory, some of them drop or fell on the ground, mis-handling such as removing the battery immediately with out turning off the power switch because they want to replace another simcard,when try to turn it on,no response on the phone. this can not be fix by updating it on the internet or what ever free software maybe,it will not be detected by the computer if the phone is already dead. Possible to fix this problem with the use of gsm gadget and it is available in any mobile service shop near you.

You have to set the MESSAGE CENTRE NUMBER before..
Go to MESSAGE settings and check the message centre number,if its not exist,call your SERVICE
PROVIDER and ask them about the number of message centre then write it on your message centre number of your mobile
