How do I know which file size area should I use with the phone?
ok For example N73 :

ON JAF we have those address:
Erasing cmt zone 00080000 - 00731421 ...
Erasing cmt zone 00000000 - 0005FFFF ...
Erasing cmt zone 001E0000 - 001FFFFF ...
Erasing cmt zone 00880000 - 00FEFFFF ...


OK which one is high ?

Highest Address of a Rap is : 00FEFFFF

This is not a full size flashes can be 8,16,32,64,128.......MB

00FEFFFF is small under 00FFFFFF , Then our flash in N73 00FFFFFF HEX Address . Now we need to convert it to MB Size .
Open windows Calculator go to menu view then scientific then choose HEX

Write 00FFFFFF Click on a DEC and you will get a result : 16777215 it's in bytes . this divide on 1024 and you have result in KB ~16348 So now your Size are 16 MB

Note : CMT is Rap3g , Same name . Also all these file must flash it in MCU Window .
