Hi

I've got a problem with a Drivetrack 71 (2588),
I've patched it, the operation proceeded normally "loader ..."
she turned on again no worries

but PROBLEM !!!
after turning it off to turn it on again, the screen remains black with white streaks,
it does not turn off,
and is no longer recognized on Garmin Express

any idea to solve the problem?
there was indeed the 154bin file on the microSD

thank you
Toox
