thanks for your replies. I have reflashed w/ q4b09.rom and it boots completely.
I still have an audio issue when booting like a "glitch sound". Is that normal ?
any ticket about that ?
Now that i boot completely, is there priority tickets in the trac for xo-1.75
to test/fixes (i haven't dig yet in the trac of the source code).
