So from 7.0.21.r3875 (safe flash)
via 7.3.6.r3582 (system flash according to the .pdf)
to 7.4.6.r7317 (safe flash)
This is what I had to do in the end, to get my mini working again without spontanious reboots when going to some shortcut. No clue on what happened when I first upgraded the fw.
@Snowmiss. Are you saying that after performing these steps you had no spontanious reboots again??
Is this the solution to the (our) problem?
Indeed, I haven't had spontanious reboots in the last three days. So I don't expect them in the future neither.
Oh, and be patient when you follow this procedure. The system flash to r3582 took almost five minutes or so. Oh, I almost forgot: going to r3582 took two flashes. First the system one and then a safe flash (it is mentioned in the readme file).
No luck for me..
Tried to go back to 7.0.21.r3875 (safe flash) tried both the USB ports and different USB-sticks (formatted normal FAT32) but installation (downgrade) process doesn't start.
So did (again) a system flash to 7.3.6.r3582 and a safe flash like you suggested. Then a safe flash to 7.4.6.r7317. Added the shortcuts, played a movie from NAS. He, it works! Retried it again, REBOOT, AAAAHHHH!!! After some more retries, reboot after reboot..
So NO (slow) fancy GUI for me, but a (fast) working GUI (3582).
Hope there will be a new firmware release soon, that accidentally will solve my problem.
@Duivels Any news on that???
Thanks for your help, unfortunately for me without succes..
