help needed to recover BB rev. B, please


After days of struggle I was able to run Angstrom on my rev. B Beagle
Today I decided to update x-load and as result my board is bricked
with UART and MMC interfaces not responsive.
Only the power on LED is active.
The USB OTG seems to be working, at least PC enumarates it as
Help me, please.
Is there a documented way or recovery from alternative boot methods
(USB, JTAG, ???)
I have done my searches, but none of the recovery methods worked for
As I am in Australia it would cost money and time to send the board
A conclusion for designers to make it almost impossible to brick the
board by reflashing and
make a simple, well documented recovery.
