Guys i need your help with my V800 !

Guys , today i try to flash my dead SE V800 with SemcTool 2.2, and i get this error :

Bypass boot authority
Phone OTP CID: 29
Load data for flash
ERROR: 301014 <--- what error is it ?

i try to search at google nothing found. i flash it with DCU-11 (modded, Prolific usb-to-serialbridge) is this cable okay ? or should i use Serial T28 cable (service cable) ??

why your not using semc 3.3 is batter you can flash and unlock

hum... i try it, but they remove ARM Flash ... how to flash LoLx ...
