I have the w518a from at&t and would like to change the big button in the middle that goes directly to the internet and also install the Chinese editor. From what I read in this website, in order to accomplish this, I need to "debrand" to w508 by using a2uploader with firmware and custpack. Currently, my phone is on firmware R1EB009 DB3200 CDA 1220-7732. So far, I have located all the Taiwan firmware as listed below.

W508_R1EA030_MAIN_TAIWAN_BR_RED53
W508_R1EA030_FS_TAIWAN_RED53
W508_1222-5039_R4A_Customized_Taiwan

1. Would somebody help to confirm that I have the correct files.

2. It looks like the Taiwan Chinese (zt) is different than Hong Kong Chinese (zh). Would anybody advise which file I need to change so that I can get the Hong Kong Chinese (zh) language? Or, do you think the Hong Kong Chinese (zh) is already included in the FS file below?

Thanks in advance for all your helps,
