Hi,
With A2uploader i've selected W910_R1FA036_MAIN_VODAFONE_SH_RED52.mbn and W910_R1FA036_FS_VFE-LIVE-A_RED52.fbn, then the process finish without any errors. The custom i've used ( W910i_1201-6277_R13A_Vodafone_PT_Portugal) with 63 files and 1 folder, and no errors during the process. Probably or maybe was necessary flash again the phone i don't know.
Thanks for support.
