Restarting after Download Fails

If the download fails, exit IPL by rebooting the terminal.
If possible, determine what caused the download to fail. If a communications failure
occurred, check all the cables between the terminal and the host to ensure they are secure. If
the hex file is too large to fit in the terminal's Flash disk, reset the hex file's size (refer to

Explanation
This error is occurs when one of the critical partitions
(Windows CE Core or Partition Map) has been received
with no apparent errors, but the received image does not
pass the checksum check. The most probable cause of this
error is a failure of the tool used to generate the image. If
this error is displayed, then the original contents of the
partition will not have been changed as the error is detected
before any flash is updated.
This error is caused when the image has been written to
flash, but cannot be read back correctly. It only applies to
critical sections of the flash, and will prevent an exit from
IPL as a critical section of the flash is damaged. If this error
occurs, the terminal needs maintenance. Contact Symbol
Support for help.
This error displays when the terminal is removed from the
cradle during an IPL session. The terminal should be
replaced in the cradle when the host is no longer
transmitting an image, and the image should be resent to
the terminal that lost the connection. Disconnecting the
serial cable does not generate this error, and attempting to
reconnect the cable will result in an Image Corrupt error.
This error indicates that corrupted data is being continually
received from the cradle. The most probable cause of the
error is an obstruction on the IrDA window on the terminal
or the cradle. If cleaning the windows fails to correct the
problem, then the terminal requires service. Contact
Symbol Support for help.
