thanks heaps.
phone is ok now. i flashed main and fs with r4ek001.
then customised. i tried to patch it again with a sim lock patch.
it died again.
is there another patch

if you want to patch to remove sim lock
you must take notice if Patch file supports your phone?

or else you must create it by youself with tool "Sim-Lock Patch Generator"

crate by Browse .mbn file (that you used) then press make patch

W810_R4EK001_MAIN_GENERIC_HN_RED49.mbn
W810_R4EK001_FS_AMERICA_2_RED49.fbn
Remove_SIM_lock_W810_R4EK001.vkp

yeah. i already have the "Sim-Lock Patch Generator".
i made the patch with it and according to the log successfully patched it.
it just doesnt turn on when i finish.
