SDS100/SDS200: Losing keys after roll back

[dispatcher812]

With help from forum user pro92b, I know where to get the firmware I am currently on incase i need to roll back. Reading the test file that cam with the zip file it mentions the keys if purchased will remain stored in the scanner so you can use it by returning to the latest firmware via Sentinel. So does that mean if I update to the current firmware, and roll back I can't use the keys until I am back up to date on firmware? Can I reinstall the key?

You don't need to reinstall the upgrade keys. If the firmware you are currently using has the waterfall feature in it, it will recognize the keys that are stored in the scanner. If you revert to older firmware that doesn't have the waterfall feature and then re-install later firmware with the waterfall feature, the keys in the scanner will be recognized.

Rolling back the Firmware does not effect your paid for keys...
The only one that might get effected would be the Waterfall function (if your talking about the SDS series) would not work. But the key should still be loaded and should work when the fimware is reloaded with the waterfall feature...I

The keys are stored in a different section of the memory. Changing FW does not normally touch this memory.

In the case of the SDS100/200 if you roll back the firmware to before the waterfall firmware then the waterfall option will not work.
