One of my microbit seems to reject the 1.9.2 runtime.
uflash -r microbit-micropython-v1.7.9-gbe020eb.hex
and in REPL, i get
>>> MicroPython v1.7-9-gbe020eb on 2016-04-18; micro:bit with nRF51822
uflash microbit-micropython-v1.9.2-34-gd64154c73.hex
and I get nothing in REPL
In both instances, the device usb drive mount and unmount properly.
With v1.7.9, I can install and run programs. However seems that the accelerometer it not working.
I suspect the board is fried somehow. Before I toss it, anyone has any clue what could be the problem or how to diagnostic something like that?

Re: micro:bit not working with 1.9.2
My microbit is working fine in v1.9.2, maybe the new firmware is not good. you may try it in MU 1.0, it using micropython 1.9.2.
Re: micro:bit not working with 1.9.2
Thanks for the suggestion. Actually started with MU and that's how I realized there was a problem and tried to isolate it using uflash. Those runtimes work fine on another board, so I suspect this board to be defective. Unclear why that's affecting flashing new runtime.

Re: micro:bit not working with 1.9.2
How are you entering a REPL session, using Mu or a program such as screen?
Have you tried running microbit.i2c.scan(), it should return a list of 2 integers [14, 29]. One is the address of the accelerometer, the other the compass
