Can't boot past splash screen

ok i entered sudo pacdiff and overwrote existing files to merge updates

now if i try to login as regular user or root in tty it returns
Login incorrect

I guess you overwrote not only profile but also shadow which stores login and password information. I would recommend next time to view changes and apply them line by line where necessary. And don’t overwrite shadow.

i remember option to chroot available through live USB for repair options
when i try to boot , the installation stops at
FINISHED TLP system startup/shutdown

Does that mean you can not boot to live USB? If you can, try to chroot manually. I think there are some how-tos on the forum or on the wiki. If no luck, maybe reinstall is an option too.

EDIT. Here is solution of a similar problem:

Chose "overwrite" old files with .pacnew - now can't login

Use a live iso and open a terminal sudo manjaro-chroot -a Then check if you have these files # /etc/shadow- # /etc/passwd- These are backups - list their content - they should contain your username # cat /etc/passwd- # cat /etc/shadow- If they contain your username copy them to their original # cp /etc/shadow- /etc/shadow # cp /etc/passwd- /etc/passwd Edit: 2020-09-01T05:40:00Z (UTC) Another candidate for verification is /etc/group
