Black screen / emergency shell after update

I just did the update as I do every time I see mirrors refreshed.
Black screen on restart.
Left it for an hour.
Still black.
PowerOff.
Can get to kernel versions to select, but after some HD light activity, nothing.
Let it sit for hours. Still black.

I remember seeing from different things in the update fly by that said “not enough room” etc. As I was watching I would open up the disk manager and check to see that there was plenty of space.

I am currently booted onto a Live USB, and my next step is to see if I have a pretty recent TimeShift.

I will check back here to see if anyone suggests getting information from logs, etc. At one point trying to boot, I was able to do the systemctl ??? that allows one to see logs. I took pictures
Google Photos

First Error I saw listed
Google Photos

Here is everything after I saw the first error.

Help as you are able please. But I will report back if I am successful later with TimeShift

Thanx!

Here is my lsblk:

I am booted on Manjaro Live USB version 18.1 but no TimeShift is installed. Trying to figure that out!

I am now trying to use this:

…but I am going to need some hand-holding please?

I am stuck on step 4:

However!
I mounted sda3 and I can indeed see my home with things in it.
sda2 is a swap

The guide your following is old and outdated. Use manjaro-chroot -a instead and follow this guide:

Thank you!
I have taken that first step.
The end has end kernel panic - not syncing: No working init found. Try passing init= option to kernel.

I plan to use a few more of the listed changes for editing the grub to see if I can get past this unless you suggest otherwise.

Thanx!

P.S. no tty is possible. Tried that. Just complete black screen.

Sorry for my english.
Is it Manjaro who runs Grub, or is it another distro ? Others one does not load the necessary microcode for Arch & Manjaro .
In this case, you need edit grub menu with E key and add the intel-ucode our amd-ucode after the linux /boot… line like this eg:

No problem with English!
Thanks for replying.

Did you read the link posted previously?

I don’t want to try to go down two different paths, so, do you feel your recommendation is helpful beyond the previous direction?

And even if you do, I will need more direction since I do not understand what you are suggesting to do.

If I had to guess… It seems like the issue is init, obviously, so maybe the only issue is just what it says… That I need to give it a proper init (location?)

I have successfully booted from a Live USB with Manjaro 20 on it.
Once booted, I opened a terminal CTRL-Alt-T and offered this command:
sudo timeshift --restore

This gave me a listing of all of my backups.

I put in the right number and took the defaults to restore.

After restoration, I booted without issue.

Then I did the update from the GUI.

The update went well.

Thanx for the help all!

I just started the latest stable update via terminal and noticed some failures.
They seem to indicate they have been dealt with, but I am concerned and will put off reboot until I hear back form someone. I thought this was the best place to put this, because this MAY be connected to why I had to restore on the last update.
Please let me know what you think?

The 5.7 & 5.8 kernel are EOL (End Of Life) and are no longer supported. Use Manjaro Settings Manager > Kernel to remove them. I see you’re already using the stable 5.9. It’s also good to have an LTS kernel installed as backup like 5.4.

Thank you kindly for the response.
So you do not believe this had anything to do with my previous black-screen problem, right?

Thanx again!
