Im new with this flashing on phones.
I just downloaded XS++.. opened the software and connected my phone....and viola..i was able to get other info about my phone.(my first accomplishment.hehe)

Some concerns regarding FLASHING in XS++:
1. Flashing the MAIN and FS with XS++ -- i will be needing a MAIN file and a FS file (correct me if im wrong?
2. How about the Customization, will i be needing another file for this or it is already preloaded in the XS++ itself?
3. Is it possible to just Flash the MAIN and FS without changing the Customization? (any side effects)
4. Are there compatibilities in choosing the MAIN and FS file in flashing. Example, if im using K800_R1GB001_MAIN_HONG_KONG_RED49 for the MAIN file then i should ONLY using the K800_R1GB001_FS_HONG_KONG_RED49 for the FS file? by the way, what is the extension name of those files?
