[Q] Modifying System Files & Signing 'refhashlist' ??

So I modified this file /etc/dbus-1/system.d/dnsmasq.conf .

It worked fine and smoothly. Now today, my phone died while I was asleep because of very low power and was causing REBOOT LOOPS. Nonetheless I managed to bring it back to life via R&D Mode. Reverted the changes I made to dnsmasq.conf. Then disabling the R&D Mode and going back into Production mode removed the bootloops.

Now whenever I want to make changes to dnsmasq.conf again and When I reboot the phone, it goes into bootloops again.

Somewhere I read that proper signing of REFHASHLIST is required.

Found this refhashlist patcher by coderus Here.

But how to use it AND do I need inception/openmode to sign the list?

I have this script of coderus to resign refhashlist:

Code:

#!/bin/sh

#refhashlist patcher

cp /var/lib/aegis/refhashlist /var/lib/aegis/refhashlist.backup

pathname=$1

if [ "$pathname" == "" ]; then exit 1; fi



line=$(grep "${pathname}" /var/lib/aegis/refhashlist)

if [ "$line" == "" ]; then exit 2;

else

        #oldsha1=$(for ii in $(sha1sum /${pathname}); do echo $ii; break; done) #real file sha1

        #oldsha1=$(i=0; for ii in $line; do i=$((i+1)); if [ $i -eq 6 ]; then echo $ii; break; fi; done;) #sha1 parsed from line, not real sha1

        oldsha1=$(echo ${line} | sed -re "s/.*([a-f0-9]{40}).*/\1/") #faster sha1 extraction using regexp

        newsha1=$(for ii in $(sha1sum "/${pathname}"); do echo $ii; break; done)

        newline=$(echo ${line} | sed -e "s/${oldsha1}/${newsha1}/")

        sed -i -e "s@${line}@${newline}@" /var/lib/aegis/refhashlist



        accli -c tcb-sign -F /var/lib/aegis/refhashlist < /var/lib/aegis/refhashlist

fi

stored it in MyDocs/Temp1 folder.

but when I execute it, it gives the following error:

Code:

home/user/MyDocs/Temp1 # /bin/sh refhashlist.s

h etc/dbus-1/system.d/dnsmasq.conf

refhashlist.sh: line 18: syntax error: unexpected end of file (expecting "fi")

I do have Inception Installed. any help?
