Sorry, I missed this question, just saw it again now...Originally Posted by 4DRSS
The upgrade from V2.4.x firmware to V2.5.x firmware requires a new boot block in the FlashScan memory. The boot block is the underlying software that controls the FlashScan hardware. Sort of like the BIOS in your PC.
The boot block is not very "smart", it just has a bunch of low level hardware "driver" functions. The firmware invokes boot block functions to manipulate the FlashScan hardware - to reprogram the flash memory, to control the LED's, the keypad and the USB coms etc.
The boot block is not designed to be updated regularly since the underlying hardware will never change. However, we needed to make a change when going from V2.4 to V2.5. The change involved some very low level hardware instructions.
Once the boot block has been upgraded to V2.5 it is no longer compatible with the V2.4 firmware. That means you can ONLY run V2.5 firmware once the boot block has been upgraded to V2.5.
We deliberately chose to not allow downgrading to V2.4 because it would allow too many combinations/permutations of boot block and firmware versions to support effectively.
