Downgrade Instructions:
The easiest way to perform a downgrade is to rename the file (with the old version you
want to downgrade to) to a version higher than the one that is currently in the set. So if
version 1.03 is currently in the set and you want to downgrade to v1.01, you should
rename the file "8400-14001_01.bin" on the Compact Flash to "8400-14001_04.bin".
Forced Download Instructions:
The "Downgrade Instruction" procedure can also be used when software is partly written
to the flash (for example, in the case of a power failure).
Before upgrading, the software versions (on the CF card and TV) are compared. If the
versions are the same, the upgrade is automatically cancelled. A partly written flash can
never be upgraded unless the system is fooled by renaming the file as described in
"Downgrade Instructions".
