First, thanks to all for the responses.
Finally, it seems a problem with the voltage. I've used a 5v 2.5A (5.02v effective) power adapter, and it wasn't work. Now, I've replaced with a 5.2v 2.6A (5.11v effective) power adapter and it works always, and with all images.
Thanks again!
Glad you got it sorted out and were able to get your Rock64 up and running!
From an engineering prospective, the 5.02 volts should have been just fine so most likely you got bit by something else like the power supply's ripple and noise spec.
A lot of power supplies designed as 'quick chargers' are pretty noisy, and this can be a big issue when powering a system with more stringent ripple and noise limits.
Hopefully, for future prospective Rock64 users, your experience will help them avoid problems.
Price wise, the official 3A power supply is quite a bargain, and should help avoid these kinds of issues.
