If i want to upgrade my firmware for my n6630.Should i clear all thing in my handphone first and then make a new flashing or just upgrade?Which one is safer???Cause rumor says that doing the 1st method is much more stable then the 2nd one.Is it true.By the way N6630 latest firmware for APAC version release yet?I will be gratefull to have your ideas thank you.

you should backup your phone data first before you flash your phone. then you will not lose all your data. 6630 firmware have not release a new apac version yet.

i know what u mean by backing up the data.But recently i went to a shop they told me that there r 2 method one is upgrade directly to newer version anot is clear all things in a phone and make a clean install.Just like computer upgrade the older version operating system directly to newer one and anothor format a hard disk and make a new operating installation.You get wat i mean?So which method is more reliable method?By the way when will the APAC version release usually few month later from the EURO version or weeks?

you need phonix & DKU-2 to upgrade your 6630 firmwave
