ok i used the XS++ and flash the phone with W810_R4EK001_MAIN_GENERIC_HN_RED49 as main and W810_R4EK001_FS_AMERICA_2_RED49 as FS. But at the customize file system's BreakXS and FastXS alway boot up the wrong CID and when in BruteXS never get the work done. It jumping from "Sending loaders\db2010_cid49red_cs_r5a.bin..." to Read otp and connect and disconnect the phone itself. is there another way to "finalize" or customize the FS w/o using FAR or XS++? because my FAR never functional. Thankz
