I had installed the CM 11 m8 on my phone D805, wore philz recovery, but had to switch to TWRP to install the CM, and I had a backup that could only restore it by philz, so I flash the philz when I try to connect my phone, gave error, those little letters that appear on top it, and try to turn it usually appeared lg logo and the low, Security error. Using tried FlashTool but this log appears:

Excuse me, google translate,

In my language:

Eu havia instalado a CM 11 m8 no meu celular D805, usava a philz recovery, mas, tive que mudar pra TWRP para instalar a CM, e eu tinha um backup que só conseguia restaura-lo pela philz, então fui flashar a philz, quando fui tentar ligar meu celular, deu erro, aquelas letrinhas que aparecem la encima, e ao tentar liga-lo normalmente, apareceu o logo da lg e a baixo, Security Error. Tentei Usar o FlashTool mas aparece esse log:
