debrand cid52 db3150 z750 from att

[Khigh]

I want to debrand my z750 from ATT's crippleware preferably using a2uploader.

I have found the download section and just don't want to brick my phone
what files should I download to get this phone to sony ericssons most up to date firmware? I have flashed a w580i before with jdflasher, and have flashed a z750 with dclient this didn't seem to require a custompack choice..

my main worry is probably choosing the correct files so not to brick the phone

use any GENERIC MAIN with CID52 and for the FS, read here : Top Sony - Languages Description and select the requird region and use the custpack which match the FS

EDIT: ignore the post below... I chose those and the bottom generic world one.. PERFECT thank you for your help....

okay so I pick
Z750_R1FA030_MAIN_GENERIC_2_DA_RED52
Z750_R1FA030_FS_AMERICA_RED52

im sorry I don't follow to well on the custompack thats where I was most confused since I didn't have to choose the first time around...
and which one of these ?
