StealthMiner Update 1.2.6-rc2

The StealthMiner uses a white label Vnish and new update is out with new features and a pleasant surprise of 3 more "tuner" settings added to the JPro+ model boards used in the StealthMiner JPro+ model.

Previously, the tuner profiles covered ~27-30 TH operation on the StealthMiner with Noctua fans and unmodified APW3++ PSU. Nominal operation has now opened up to ~21-30TH, and those are the numbers I feel safe claiming. Some boards have gone up to 32TH on the Noctua + unmodified APW3 combo before. Individual boards may vary in performance even when ambient conditions are the same.

This update brings a whole list of changes. Up until today, StealthMiners were loaded with 1.2.5-rc2. Below are some highlights pertaining to the StealthMiner JPro+ model. (Complete changelog available here)

Installing the update:

1. Download the appropriate update file for the JPro+. Some of the earliest units went out with SD card installs as we couldn't load direct to NAND just yet.
1. StealthMiner JPro+ Beagle Bone NAND update
2. StealthMiner JPro+ Beagle Bone SD Card update
2. Navigate to the Firmware update screen and load downloaded '.tar.gz' file. Do not unzip the file, just load it as is
3. Walk away for about 10 minutes and allow the firmware to load
4. You might need to close the tab and reopen or even clear cache for update to show in UI.
