Switching to Update Mode on the Pearl:

  • On original Pearl models with firmware 1.83 and newer, connect your scale to the Pearl Updater app, then tap the "Switch to update mode" button that appears once the scale is connected. The Pearl will then display "F.u. 2". Once you see this, Long-press T to enable Update Mode.

  • While your scale is off, hold the Power Button until it shows “nACAIA” -> “SEt”, and then hold the T button at the same time. 
  • Hold both buttons until you hear a beep and the display shows F.0000. Release buttons.
  • Enter the appropriate passcode for the version of your scale. Short-press T to change digits, long-press T to move to the next digit.
  • For firmware 1.3 and older, input 1249; for firmware 1.5 and newer, input 0415
  • The scale will display UPdAtE (for firmware 1.3 and older, the scale will display "ISP" when it is in update mode.)

Pearl 2021

There are currently no firmware updates for the Pearl 2021.

There is no need to switch to Update Mode on this scale as it should switch automatically when connected with the Updater app. 

If you can not switch it automatically, you can manually enter Update mode by performing a soft reset or holding the power button while plugging in the scale.

During the update process, the data transfer indicator on the bottom left will flash. 

 

* Note: If you want to leave update mode, please connect the scale’s USB to a power source. The scale will power off automatically if the update process does not begin shortly.

Why does the Pearl Updater not connect with my Pearl 2021?

The Pearl Updater only connects with our original Pearl scale. The Pearl 2021 connects with the Acaia Updater scale, like the rest of our scales and bean dosers.
