Me contesto a la pregunta de como restaurar a valores de fabrica para mandarlo al SAT, estos son los pasos:
Imagine you have to send your Milestone to the customer service, would be better if it was "clean" or you want to downgrade it ? Here is how to :
- 0 : What you need : A Windows (sorry ^^), RSDLite and the drivers 32bits or 64bits
- 1 : Choose the right .sbf from
here
- 2 : Plug the USB and shut your Milestone down
- 3 : Boot it in bootloader mode (press the D-PAD UP key while pressing the power button)
- 4 : Launch RSD Lite, your device should be in the list
- 5 : Select your .sbf file and click on start ans let it do, your phone will reboot at the end
Here we are, you have your clean Milestone !
