First of all, welcome to the forum!

Force the machine off; press power button 4-5s.
Then put in DFU with keys combination.

BTW, connect charger cable before DFU cable.
Also keep the battery connected.

No veo ninguna razon para repetir entero un post visible unos centimetros mas arriba.

Tanto en restore como revive, te sale mismo errorarriba mencionado?
Has conectado primero el cable del cargador?

Asegurate no tener corto en ninguna barra de tension secundaria.

Prueba DFU con U4770 vacio.
No olvides hacer un backup primero!
Tambien puedes probar con ese:

Eso es, el adaptador que necesitas.

Imagino que necesitaras una tarjeta adaptador para USON3x4 tambien.
No creo que la que viene con CH341 tenga los pads para ese modelo.
 
acabo de soldar por probar la rom de la placa ebay y ahora si conecta en DFU pero sigue dando el mismo error en el mismo punto, pienso que no tiene nada que ver con la rom
