You need to post your hardware info here to see if someone can help you, especially your graphics cards (Maybe?)......
* P.S > And I'm just curious, if you failed to boot, how did you run "update-grub" command? At least you need tty to run these commands......

UPDATE: System AMD Ryzen 2400G RAVEN Vega 11
The issue is in fact graphics related- Boot Failure at Fb0: switching to amdgpudrmfb from EFI VGA. Can load with "nomodeset" kernal parameter, however I am stuck at an unfavorable resolution and without audio output.
Is there an offical place to file a bug report to Deepin developers?
------------------------------------
When attempting to boot from image-5.7.7 or 5.4.70 I get a blank black screen. Image 5.4.50 boots fine. I was using 5.7.7 for quite some time until this [10.22] https://www. deepin .org/en/2020/10/22/deepin-system-updates-2020-10-22/ broke it.
Today I ran the 11/11 and 11/13 updates https://www.deepin.org/en/ with the new 5.4.70 kernal and that fails to boot aswell.
boot.log and journalctl --last-bootdo not record the boot attempts of the failed boots. I don't see anything notable in syslog or kern.log but that may not mean much.
Ran update-grub but that didn't help.
Where to start? Thanks.
