How to restore chains OUTPUT and PREROUTING to default values?

[Mircica]

Old router RT-AC66U

Operation Mode:Wireless router Firmware:374.43_45EAj9527 SSID: (2.4GHz)Linksys(5GHz)Linksys 5GHz (Merlin LTS fork)

After:

# Delete old YAMalwareBlock rules.
logger -t Firewall "Delete old YAMalwareBlock rules."
echo Delete old YAMalwareBlock rules.
iptables -t raw -L --line-numbers | grep YAMalwareBlock | cut -d' ' -f1 | sed '1!G;h;$!d' | while read number; do iptables -t raw -D PREROUTING $number; done
ipset -L | grep YAMalwareBlock | cut -d' ' -f2 | while read setname; do ipset --destroy $setname; done

I want to reset/flush those 2 Chains to default!
Tried all I found in this forum but didn't work...

reboot after was properly done, twice!

Do you want to uninstall that script? Usually the raw chains are empty.

Yet another malware block script using ipset (v4 and v6)

As if we don't have enough already :p Here is yet another malware blocking script that uses ipset (v4 and v6). So why put up another one? Over 650 Million unique IPs blocked Simpler (minimalist script with only 26 lines (which includes a couple of blank lines and comment lines) Quicker...

No, I just changed the blocking list:
"ya-malware-block.urls"
but still some IP addresses from the old one remained blocked even if they are not in the new list right now!
Quite curious how to get rid of all of this!
So I thought I escaped when uninstalled and reinstalled!
But this is not the case apparently so what can I do?
