1800E can't be updated Hi. I'm sitting here at my father-in-law's house and he has asked me to install/get working his 1800E. I have downloaded the update files from several different links and they all result in nothing. After a few minutes of installing from a freshly formatted SD card, it says the following: E: failed to mount /system (Invalid argument) E: failed to mount /cache (Invalid argument) E: failed to mount /cache (Invalid argument) Formatting /cache E: Invalid command argument Finding update package... Opening update package... Verifying update package... E: failed to verify whole-file signature E: signature verification failed Installation aborted I am beyond frustrated. Any help would be appreciated. Thanks/
