Here are a few different ways to solve the problem:
This can happen when the miner has been Reset. Leave the miner to do its thing and it should sort itself once it has finished re-creating all the partitions and unpacking its copy of the blockchain.
Power down the MerryIoT Helium hotspot, re-seat the SD card. Power it back on
If this didn’t solve the problem, reset the miner again and check back after a few hours
Finally if none of the above worked, contact: email@example.com They will be able to fix it remotely. Please note however that it can be a few days before the Browan support team gets back to you.
