Need Help debranding my K770i CID53

[riders4sia]

if you use a generic main, then you only need to flash the FS and Custpack only. you can't just flash different custpack coz you will end up having configuration error

Hi riders4sia. Thanks again.

So just to be sure. I flashed this main onto my phone K770_R8BC004_MAIN_GENERIC_VI_RED53.rar the other day. I would now like to put "3 uk" branding back on as has more compatible 3g and internet settings. Will this FS and cust pack do the job?

K770_R8AB001_FS_HUTCH_1_RED53.rar
K770i_1202-4418_R7A_3_United_Kingdom.zip

Also I have been snooping around in the Customize.xml from the custpack. Just incase I reflash and I get back that horrid 3 menu, will it effect the operation of the phone if I change a few things in this XML document?.

for example

</media>
<java>
<midlet deletable="false" upgradeable="true" install="true" movable="false" folder="APPLICATIONS">
<jar-file>java/Messenger.jar</jar-file>
<jad-file>java/Messenger.jad</jad-file>
</midlet>

Here i would change the line from midlet deletable="false" to midlet deletable="true"

Also how would I keep the ability of fast forwarding large MP4 files with out it skipping to the next file?.

Oh and one more, how to keep the ability of using different flash desktops/Menus?.
