I everybody. i'm sorry for my poor english

unluckily for me i'm a commodore pmc30 buyer.
i tried to upgrade my pmc with your 1.2.4 firmware and it seemed run without problem.
when i turned it on for the second time the screen displayed me a lot of colorfull stripes like when you set upper resolution on your screen then the supported once.
i tried to reboot it and the problem went out... it seem to exist randomly.
now i saw that on this board there are also other pmc30 users that use 442 fw and i want know if they had the same problem...
there's another silly qestion, there's the opportinity to change my pmc30 with a 442v2 like as your product with the charge of 99$?
