MySQL is Dead - In Desperate need of help

Quick backstory:

I've been trying to upgrade/optimize server, using anything from PHP-FPM and MPM Event with xcache, even as far as nginx/Engintron ... never had any real luck with any of them...

After uninstalling (pick any of the above mods), I've been left with a dead MySQL server. I can not start it, debug it, upgrade it, anything.

EasyApache is stuck @:
!! sub-step '1' !!
!! sub-step '2' !!
Cpanel::DBI::Mysql connect('','root',...) failed: Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2) at /usr/local/cpanel/Cpanel/MysqlUtils/ line 136
I ran EasyApache after instructed to do so after my latest WHM MySQL Upgrade (5.5 was not available, only 5.6, which I did). This supposedly worked and instructed me to now recompile apache/php... which I tried.

I've tried this suggestion
/scripts/update_local_rpm_versions --edit target_settings.MySQL55 uninstalled
/scripts/check_cpanel_rpms --fix
/scripts/update_local_rpm_versions --edit target_settings.MySQL55 installed
/scripts/check_cpanel_rpms --fix
This, and any future #service mysql start result in the following (via error log)
140906 14:42:05 mysqld_safe Starting mysqld daemon with databases from /var/lib/mysql
140906 14:42:05 [Note] Plugin 'FEDERATED' is disabled.

140906 14:42:05 mysqld_safe mysqld from pid file /var/lib/mysql/ ended
I'm totally stuck. I can't seem to upgrade/side-grade/downgrade/any-grade to get this server running.

Never fails, I post for help, after hours (days actually) of issues... then minutes afterwards, find *my* answer.

rm /var/lib/mysql/ib_logfile0
rm /var/lib/mysql/ib_logfile1
