Hi!
My Z83-4 Pro went dead, does not power on. It was like this guy's:
https://theminixforum.com/index.php...n-on-after-firmware-update-and-shutdown.2298/
So I removed CMOS battery for a while like it was shown on the video, but without getting any better.
I've supposed that BIOS is corrupted, so I read out all SPI flash content as a backup with cheap SPI programmer. I have downloaded BIOS image from official site and overwritten BIOS memory area. Now it still doesn't boot up, but LED blinks approx 1 time per second, looks like trying to boot, but resets all the times.
Log from UART:
Can anybody help with understand the problem and fix it?
Thanks and regards.
