  1. HELP I only have 4 digit pin but in update it wants my pin but more than 4 numbers I don't have more than 4 I'm screwed!

  2. I am getting the message "MCU Firmware is Outdated" when plug in the device. It is not asking even PIN to open. My current firm ware is 1.3.1
    I tried using Bootloader also by pressing 5 seconds. 
    Ledger live desktop is updated.
