1. Download nRF's DFU app from iOS App Store or Android's Play Store, you can find the app by searching for `nrf dfu`, the app's full name is `nRF Device Firmware Update`
2. On flasher.meshcore.co.uk, download the **ZIP** version of the firmware for your nRF device (e.g. RAK or Heltec T114 or Seeed Studio's Xiao)
3. From the MeshCore app, login remotely to the repeater you want to update with admin privilege
3. If updating a companion, skip to step 6 below. If updating a repeater or room server, from the MeshCore app, login remotely to the repeater you want to update with admin privilege
