When to Use These Features
Consider the reset, resync and fast sync features in this order: prescription medicine, OTC (over the counter) medicine, and supplement. The first two treat symptoms and the last one only boosts the immune system. Resync will reload the snapshot, while the Reset feature will not only do the resync but will also rebuild the docker.
You should always try the resync feature first. If the system notification shows the resync was successful, you can then follow up with a Fast Sync to boost syncing speed. If the system notification shows the resync failed, then opt to utilize the reset miner option instead. You can still follow up with a fast sync once the reset is successful.
This is an alpha feature that gives healthy miners a sync boost, so they can quickly catch up to the top of the blockchain from the block they are syncing at.
IMPORTANT:this feature will NOT work for healthy miners whose gap to the blockchain is smaller than 400 blocks.
This action deletes the blockchain data. It does not, however, delete the Helium software. Your miner will start syncing from 0.
Consider this a system wide wipe over. This action deletes both the blockchain data and the Helium software. Your miner will reload everything and start syncing from 0.
