thanks for the guide!

flashing starts fine on my xperia x until it stops with an error:

Flashing oem partition..
target reported max download size of 536870912 bytes
sending 'oem' (163040 KB)...
OKAY [ 5.309s]
writing 'oem'...

the phone is unlocked,

could anybody help me with some hints?

best regards,
