Aoc e41 (4gb)

hola a todos, tengo un AOC E41 (4gb) y de un tiempo para aca, se reinicia, u entra en modo recovery y sale "sin comandos". Pero al introducirle una memoria SD sale unas letras rojas que dice:

Sysdumpping now, keep power on.

writing done.
Press any key (Exp Power key) to continue... pressioned key 115/114
(cuando presiono la tecla "volumen +" me sale 115 y presiono la tecla "volumen -" me sale 114)

no lo reconoce la pc, ni mtk, ni flashtool, ni consola adb. y los drivers no los concigo.
no le he podido instalar un recovery y tampoco una rom.

espero su ayuda.
