Binary downloads and flashing instructions

WARNING

1. This upgrade may reset your SoftRF settings down to factory default values. Please, follow these "backup and restore" procedures prior to executing the update.
2. ESP32 only: you may try "Web update" method if your current firmware version is rc7-9 or 1.0-1.8, otherwise do:
   • follow First-time firmware installation procedure instructions instead, and
   • make full flash ERASE prior to firmware write operation, and
   • disconnect any of I2C devices from ESP32's GPIO2 pad. See this ticket for details.
3. S76G only: follow these instructions to update your Dongle Edition firmware. It is also recommended to reset your SoftRF Dongle settings back to factory default values by following this procedure.

Prime MkII, MkIII, Badge or Dongle owners! I will reject any claims if you, by any reason, will fail to upgrade or fail to recover after un-successful update!
If you are not sure that you can manage the update successfully - think about to stay on 1.8 or to buy a new board with pre-installed 1.9.
