The size of the ppkg package file is around 100+ MB, and the upgrade process is much simpler and faster. It takes about 5 minutes to complete the upgrade.

Additional Info

  • There is no requirement for you to upgrade the software version in sequential order. For instance, if your current software version is 1.53, and you wish to upgrade to 1.57, you can go straight to 1.57. You don’t have to upgrade 1.54, 1.55, 1.56 then 1.57 – unless it’s specifically mentioned in the new software version.

IMPORTANT DOWNGRADE NOTE For 2.01 or above firmware version: Do not downgrade your 2.01 (or higher) software using the 2.0 or below firmware. This will corrupt your system as the 2.01 firmware upgrade package is different from 2.0 and below upgrade package. Please contact us or your distributor if you have any doubt.
