    Hello… thank you so much for uploading this ROM to here.
    But unfortunately, Avast found a Potentially Unwanted Program, Rooter-CS [PUP] . Is it false positive? can someone explain about this Rooter-CS [PUP]?

    Not a stable rom for me. UI always crashes when I select a specified theme. May be because its a trial version… Time will tell. Returned back to previous rom of June…

    i have same error as PMT changed for the rom it must be downloaded.., but when i choose upgrade in flashtool instead of download, preloader option checked itself. Does preloader option should be marked or not? i don't want to kill the phone??

    First time flashing rom on g4s and i have a problem with flash tool. When I try the 'scatter-loading', I choose the file in rom folder and get error message (no text tho) with buttons ok (nothing happens) and help (another error, unable to launch QT Assistant). Any help ?
