bzavala: The installation processes can vary greatly. Please, don't make comments if you're not familiar with the specific process. The H100 series install requires the user actually boot the player into the OF and give it instructions to update itself, after which it will flash itself. If the power fails, at all, during this flash, the units is in essence unrecoverable without specialty hardware.
While a fully charged battery should mean you'll be okay during the flashing process as it is fairly short, be aware that if power *is* lost, your player is unusable.
