Hi again
sorry in advance when I ask rtfm questions but I got a little trouble
navigating in the wiki.
I read somewhere that JTAG pins are identified. What keeps us from making a
bit by bit backup of the FLASH via JTAG or even directly connect to the FLASH
chip.
Did somone try this with a bricked device already?
cheers
