I´m not use IE to download anything, There is not a problem with the file downloaded, the problem is that the unit is unable to boot from external flash disk.
I´m talking with a person from South africa that could reflash my unit remotely, it is not cheap by me. The principal issue that I facing is that I don´t have the Full firmware (no upgrade file), I think that I could have a chance to recover my unit with a full version of Firmware.
