Amiga Freezing/Crashing Flashing RED screen

MNT ZZ9000
1

I just wanted to share my experience of what happened after about a month of installing the ZZ9000. One day, my A4kT just rebooted one day for no reason just sitting there while I was working on something else. When it tried to come back up, the monitor just kept flashing RED screen. I shut it off and tried again and then I got a Green flashing screen and then finally came up. RED means ROMs and GREEN means RAM. So I decided to start with the ZZ9000 and reseated it and the daughter card. The A4kT was stable 15-30min and rebooted again and crashed. After rebooting it a few times I got it back and then crashed again and back to the RED screen. I read on here about and issue a guy had when updating to 1.13. I had updated it to 1.13 when I installed it.
I removed the SD card and put it in my Windoze 10 machine. I found that it was formatted in FAT but the documentation says FAT32. I ran diagnostics on it and it found lost files.
I reformatted it to FAT32 and replaced the 1.13 boot.bin file. It has been stable since.
The ZZ9000 was shipped to me with the SD card formatted in FAT.

I thought I would give an update. For some reason today my A4000T froze crashed and I got flashing red and green screens. I looked for a new ROM but it looks like 1.13 is it. I used Windoze 10 disk utilities and found that the TF card was corrupted. I reformatted and copied the boot.bin back on.
The Amiga boots fine but then I am getting the flashing Red screen again. It just did it again.

This has come from out of nowhere. It has been stable for quite a long time now. I will try reseating the card.

So I removed the card and cleaned the contacts with alcohol. I removed the daughter card and reseated it. I also cleaned the TF card with alcohol and a cloth. I also used canned air to blow in the TF slot.

So far so good…

It is doing the same thing again.
