que tipo de problemas??
hubo mucha gente con el G4 que el sat no se lo arregló por tener el boot abierto, si me dices que es por el puerto de carga puede que lo arreglen, pero si es algo de la placa no sé yo..
1. Once your phone is unlocked, it will no longer be covered by LG warranty.
As we cannot guarantee the proper operation of our hardware with custom software, we are not able to maintain the full scope of warranty for your device after you have unlocked the bootloader.
Because of that we have a responsibility to let you know that defects which may result from, or were caused by custom device-software may not be covered by LG warranty.
creo que no hace falta traducirlo..
