Hola a todos, intento actualizar mi Undro 4k nuevo pero al reiniciar me sale :

Finding update package...
Opening update package...

-- Secure check complete.

Verifying update package...
E:footer is wrong
E:signature verification failed
Instalation aborted.
OTA failed! please power off the device to keep it in this state and file a bug report!

Lo hace con STORM 1.08 1.07 1.06 1.05 1.02 y 1.01 (no he encontrado más)

Alguna idea?
