Clean Booting the CN4
If the CN4 seems to be locked up, try warm booting and then cold
booting the computer. If neither method works, use a clean boot to
get the CN4 up and running for further troubleshooting.
The clean boot process is as follows:
• initial boot > SSPB installation > reboot > DCE installation > SRs
copied to CabFiles folder > _sstransferagent.xml run > reboot >
CabFiles folder contents run > reboot, if required.
To clean boot the computer
1 Press the Power button to suspend the CN4.
2 Remove the battery pack from the back of the CN4.
3 Use the stylus to press the Reset button on the back of the CN4.
Reset button
A clean boot erases the memory in the mobile computer,
including all applications and data files found in the ObjectStore,
and loads only the default files and programs required by the
CN4 operating system.
During a clean boot, the CN4 first looks for the SSPB files on an
installed miniSD card. If no card is found, the CN4 loads the
SSPB files in the Flash File Store. Files found on a miniSD card
during a clean boot are copied into the Flash File Store and
overwrite the existing SSPB files.
