i have a k310i and a problem

i tried to unlock my k310i that is locked on to "sun cellular" in the philippines

the problem was i didnt know that there are 3 files needed

1. FS
2. MBN
3. .rar file

I need K310_R4EA031_MAIN_CHINA_DO_RED49 firmware?

i just only need this file because right now my phone isnt accepting any sim cards T_T

what you actually need is:

-FS (.FBN)
-MAIN(.MBN)
-cust pack, also called CDA (a bunch of files in a .RAR archive that you need to exctract) this is only needed when you are using far

All files are in download section. Read this:

Nice day

Use google, only write the name of your files and look for your fimware...
