I've used latest ST Link upgrade to STM32L053R8 Nucleo board (actually two of these).
It made them unusable.
ST Link shows in Windows, but doesn't work.
Also ST Link upgrade (previous and current version) fails:

JNI error returned by system: 121
JNI command error 0x10079 after cmd [-15, -128, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0,
 0, 0, 0]

My windows (7 64bit) has latest drivers.
Both boards worked before upgrade on V2.J24
