went back to 4312 can't get the update to work.
The mini keeps rebooting all the time when i flash from 4312 to 3582 and with the save flash I always get this Sorry can't work message.
please try again
and if it keeps restarting again and again after the message "install completed"
then just keep the powerbutton pressed for at least 30 seconds,
release it and it should install the firmware again but this time not the bootloader,
this should work.
please understand i am NOT saying to remove the powercord,
just simply hold the powerbutton (30seconds) IF it keeps rebooting after the install is completed.
it will then restart again (wich is normal) and this time reinstall the firmware.
if then it is completed it will work.
also try to use the tv-sys button if the logo stays on the screen
but it does not restart.
i had to do it this way as i also had this same problem
the first time i installed the r3582,
after a few minutes of frustration i simply pressed the powerbutton,
and when i released it, to my surprise it started reinstalling the firmware,
(i even thought how is this possible because i did not remove the powercord)
however finally i had the r3582 running,
then i immeditally installed r4090 after restarting the device once,
also through the system menu>> system>>system upgrade.
and it went all well.
