Apparently there are some memory issues while updating your Pwnagotchi on a PiZ02W, I suggest you add a swapfile of atleast 2GB.
sudo fallocate -l 2G /var/swapfile
sudo chmod 600 /var/swapfile
sudo mkswap /var/swapfile
sudo swapon /var/swapfile
sudo bash -c 'cat >> /etc/fstab' <<EOF
/var/swapfile swap swap defaults 0 0
EOF
swapon -s
- fix_brcmf_plugin has been renamed to fix_services
- fix_services now looks for multiple errors in logfiles. This is still a beta, so let me know if it works for you.
