How can i update my samsung i450 software

Good day. Your phone was locked to a previous network or simcard. If you dont know any self unlock code, I might suggest you to go to the nearest phone technician personnel on your area. Ask for phone reformat. Its the first option that I can give, but if you know someone with unlocking thru pc well ask them for help. Thanks

* Power Off the Phone, Push ' 7 - * - Power Button ' it will bring you to download mode,
* you need to use E210 Usb Cable (Not RJ) Install Drivers after that Run Apollo Software, Software Automatic Find modem Port, Select Your Req. file and click Download after finish wait 5 minut and Enter "00000000"

you need to download new file, download it here

*#7780# for Software reset,
*#7370# for Hardware reset.
use your lock code (00000000 - default).
your mobile gets restarted.

Hello Sir, A total white screen is seen usually when the phone's software is corrupted by infection ( Virus, etc ). Or the other reason may be that the phone's software version is outdated and needs to be updated. You have to update the software of the phone which will reset all the info of the phone. If you have the PC Suite, try to retrieve back all stored contacts and data and then update. If you are having difficulty in updating or confused, you can freely take it to a Samsung Service center. They will do it instantly.
Thank you Sir, Have a nice day.

just reset your phone once and your lock code will be reset
