Timing Attack With Cb 1903 And Removed R6t4 Doesn't Work.

hmm, i have a problem downgrading a box with CB 1903.
the R6T3 of this box was removed some time around may/june 2007, when exactly i don't know.

if i open now the nand dump with degraded i see this:

IPB Image

now if i create the downgrade kernel an open this again with degraded this is coming:

IPB Image

i'm not sure, but for me it looks correct.

but now, when i'm trying to downgrade, the timing attack works perfect, after 50 min the hash was found. but then it doesn't boot into 1888, instead it brings me the same 3 light's again like at beginning of the timing attack (error code 0022). so where's the problem?
i tried now 2 times - same problem.

p.s. if i reflash the 6683 kernel image the box boots normal. the only strange thing i could find was that the newer kenel was on CF(0). antoher xbox i had successfully downgraded had this at CF(1)
