求大神幫忙解決 無法安裝/移除tweak - iOS

請各位大神幫忙解決 我今天安裝了一些tweak 突然出現這樣的訊息

running debain packager
(reading database ... 4184 files and directories
currently installed)
unpacking winterboard (from
.../winterboard_0.93914_iphoneos-arm.deb)...
installing winterboard

trying to overwrite
`/applications/winterboard.app/default-
[email protected]',which is also in package
app.weiphone.winterboard

sub-process/usr/bin/dpkg returned an error code(1)

第二段開始為紅色字體 我已經試過用ifile直接刪除winterboard的資料夾

也進過/var/mobile/library/preferences/ 裡面把帶有winterboard字眼的plist檔
刪掉了 不過還是出現這畫面 請各位幫幫忙 感激不盡!!
