easy guide for flashing by xs++

[xbjgod]

Hi, Great guide! I got k550 also and hoping to convert it to w610 as you did :)
I got few questions though:
1. Are these FS and MAIN files can work together?
W610_R6BC002_FS_S_ASIA_LEVAN_RED52
W610_R6BC002_MAIN_GENERIC_NA_RED52

2. Is the custpack that I need is this?
HB1-06_Gen_CDA102568_110_R8A_GENERIC_S_ASIA_LEVANor this:
HB1-06_Gen_CDA102568_5_R8A_GENERIC_S_ASIA_LEVAN(what's a difference?)

3. in the step 10 in your guide, you don't chose anywhere that custpack and w610 doesn't show on "Phone Models" scroll, so how does XS++ know which custpack to use? How to make sure that it uses the right one?

actually i'm new in flashing 2, so i'm not sure about first two questions.
1. compare among these 5 mian files
W610_R6BC002_MAIN_CHINA_NA_RED52 08-14-2007
W610_R6BC002_MAIN_GENERIC_NA_RED52 08-14-2007
W610_R6BC002_MAIN_HONG_KONG_NA_RED52 08-14-2007
W610_R6BC002_MAIN_ORANGE_NA_RED52 08-14-2007
W610_R6BC002_MAIN_TAIWAN_NA_RED52 08-14-2007
expect W610_R6BC002_MAIN_GENERIC_NA_RED52, other 4 dont
seem suit for u.
2. according to the names of these two custpack, the difference between
them is cda, different cda stands for different area. i think both of them
will work fine.

3. create a series of folders in the same folder as xs++.exe
\files_to_upload\tpa\preset\custom
put the unpack custom files in the folder "\custom"
as shown below
