Hello. A while ago, I successfully installed Ubuntu MATE 20.04 on my Raspberry Pi and used it for ROS for a while. Then, I decided to upgrade to MATE 22.04 by flashing it into the card and, after some issues with compatibility, I decided to go back to 20.04. however, I just can't get it to boot correctly! I've tried many different Raspberry Pi eeprom versions; the ones from 2024 and 2020 just give me a black screen, with the light blinking four times slower then four times faster. Other eeprom versions, like from 2023 or 2022, give me a "this board requires newer software" screen, which says that start4x.elf and fixup4x.dat are incompatible. I've tried to replace just those files with the ones from the Raspberry Pi firmware repo on GitHub, to no avail.
Replacing just the .elf files ends up with "---[ end Kernel panic - not syncing: Can not allocate SWIOTLB buffer earlier and can't now provide you with the DMA bounce buffer ]---"
Replacing just the .dat files actually gives me the aforementioned LED blinking pattern, with the screen also black.
Replacing all of the start*.elf and fixup*.dat files actually leads to the board booting, but then the Ubuntu installer crashes, apparently while configuring the keyboard. Ubuntu Server 20.04 doesn't work, either. I'm using the same SD card, the same power supply and the same board as when it was working. I even tried with a brand new board, but nothing.
I've tried both the Raspberry Pi imager and Balena Etcher to flash Ubuntu 20.04 into the card, but none work. Also, it has worked with other OSs, as I've used Raspberry Pi OS to upgrade and downgrade the eeprom. Here is an image of the aforementioned screen:
UPDATE: I accessed var/log/installer/dm.txt, this is it:
