Master Control Panel (MCP) - Segger Firmware Update?

Question

Using Master Control Panel (MCP) with nRF51 Dongle PCA10000 v1.0 
 Segger is offering a J-Link firmware update - v6.10l: 
 
 Is this compatible with MCP? Is it safe to do the update?

My MCP couldn't interact with the PCA10000 board after updating to Jlink v6.x
I would suggest to stick to Jlink v5.12. 
 You can downgrade to v5.12 by using Jlink Configuration (from that version) and right click => Replace firmware.
