IIRC, the images on the Krescue should be a copy of the image made with the timestamp, 200530, and yes many users, Including myself have been facing issues, the simplest fix for it, it to update the image using the instructions given on the latest 200814…
khadas@Khadas:~$ sudo apt update
khadas@Khadas:~$ sudo apt full-upgrade
khadas@Khadas:~$ sudo do-fenix-full-upgrade
khadas@Khadas:~$ sync
khadas@Khadas:~$ sudo reboot
since the keyboard does not work you need to SSH into the device via a PC or phone, and execute the same…
If you have the legacy uboot installed in the system and you are running mainline kernel image, this is to be expected, you will be given options to change the uboot within Krescue, at that time select the appropriate uboot for the respective image…
for Mainline, use mainline uboot,
for Legacy, use Legacy uboot… etc.
I hope this helps solve your problem, if you have any other further queries please do not hesitate to ask, for every problem, there is a definite solution
Stay safe & Good day!
