Hi, I have upgrade the the firmware to 2.04.72 then I'm getting a error when trying to upgrade bootblock
V2 -> upgrade bootblock to V2.5.08 ? no/yes
The flash memory will now be tested ....... no/yes
V2 -> erasing block Block xx of 70 counting from 0 to 70
V2 -> ATTENTION Flash memory test FAILED
return flashscan for repair

Did I missed a step or I have a hardware problem ?
V2 works fine
