you only need write flex but most possible also need a Hardware change

I had a C331 that was using 850 and/ 1900 and now since I have flashed it it is now using 900 and/ 1800 MHz.

That means it is not a hardware problem but it need the correct flash file to enable it to work on 900 or 1800.

does anyone know which flash file to use?

yes using smart-clip you can do it directly, about hardware they are old phones i didn´t remember but if is directly better

if don´t have smart-Clip search for a core Europe or asia flex

i found this i used many time ago for unlock but also have 850 band and yes when you use it you get your phone unlocked Enjoy

For use only need MSS 3.5 or higher

Click on restart phone
Upload flex file
Restart phone Again
