I appear to have got myself into a similar situation.
I had managed to delete my version file in the root directory.
I then mistakenly put firmware 1.3 on the device(Not realising it was already installed).
the bunny did the whole trafficlight thing but instead of rebooting(Green) and then flashing blue the LED just went out.
I left it ages and then went through the recovery process as described in the thread linked above.
My bunny then goes through the sequence described above.
im am unsure of what further steps i can take to try and recover the device.
