I have a Sentinel DX4000, after the message “STARTUP FAILED: 0xD9” appeared on the LCD I traied to perform a system recovery using a usb stick following the recovery guide included in the manual.
When booted my stoarge with the usb stick in it, after showing for a while “INITIALIZING OK. LOADING RECOVERY” a message appeared on the LCD “Bad Storage”.
i tried the steps included in this link and this link2
With no luck
I have important data that i don’t want to loose on the storage so hardcode factory reset is not an option.
Any help will be appretiated.
