[Help] Jolla Phone

I’m able to input commands from the Recovery Mode>Shell. I ran the following commands:

mkdir -p /mnt/rootfs
mount /dev/mmcblk0p28 /mnt/rootfs
chroot /mnt/rootfs /bin/bash
rm -f /var/lib/rpm/__db.*
rpm --rebuilddb
bash-3.2# rpm -qa | grep -E 'rpm|zstd|openssl'
openssl-libs-1.0.1c-1.1.1.armv7hl
deltarpm-3.5-1.1.1.armv7hl
rpm-4.9.1.2-1.1.4.armv7hl
rpm-libs-4.9.1.2-1.1.4.armv7hl
bash-3.2# rpm -qa | grep rpm
deltarpm-3.5-1.1.1.armv7hl
rpm-4.9.1.2-1.1.4.armv7hl
rpm-libs-4.9.1.2-1.1.4.armv7hl

I also transferred the required packages to update the rpm in the Downloads folder (should be /home/nemo/Downloads), but I don’t have access to it (No such file or directory). I don’t have Zypper installed, so I can’t run that command. Would this work:
rpm -Uvh --force openssl-libs-1.1.1kgit1-1.7.4.jolla_.armv7hl.rpm libzstd-1.5.0git1-1.1.10.jolla_.armv7hl.rpm rpm-4.14.3+git28-2.armv7hl.rpm
