我的树莓派硬件是新版本，固件（包括系统自带的固件和我自己编的桌面）是老版本，树莓派上接了一个HDMI显示屏。新版硬件和老版固件不兼容，开机就出现这个提示（如图），我想通过在线升级固件来让它俩兼容。我用了apt-update和apt-upgrade命令，但升级结束后系统立刻黑屏，且无法自动亮屏，强制关机再开机后系统无显示（一直黑屏），用读卡器读SD卡发现里头啥也没有，我之前编的文件都丢了。我重新写了SD卡再放进去试，这一次我等了很长时间（30分钟以上），但仍然黑屏，强制关机再开机后系统无显示，用读卡器读SD卡发现比上次多了一些文件，但我无法确定这些是不是全部的文件。黑屏问题怎么解决？我确认我的固件下载地址、HDMI设置、代理设置等都没问题，线下的技术支持也不知道是怎么回事。论坛的朋友们有会这个的吗？求解答，谢谢！

My Raspberry Pi hardware is a new version, but the firmware (including the system's built-in firmware and the desktop environment I compiled myself) is an old version. An HDMI display is connected to the Raspberry Pi. The new hardware is not compatible with the old firmware, and an error prompt appears as soon as I power it on (as shown in the picture). I want to make them compatible through online firmware updates. I used the `apt-update` and `apt-upgrade` commands, but after the upgrade, the system immediately went black and could not automatically display. After forcing a shutdown and turning it on again, the system shows nothing (the screen remains black). Using a card reader to read the SD card, I found that there was nothing on it, and all the files I previously compiled were lost. I rewrote the SD card and tried again. This time I waited for a long time (more than 30 minutes), but it was still black. After forcing a shutdown and turning it on again, the system shows nothing. Again I read the SD card, then I found that there were more files than last time, but I cannot confirm whether these are all the files. How can I fix the black screen issue? I have confirmed that my firmware download address, HDMI settings, proxy settings, etc., are all correct, and offline technical support also doesn't know what is going on. Do any friends in the forum know how to solve this? Please help, thank you!
