CodeIgniter htaccess for semi https and without www version

Question

Instead of basic PHP, changing htaccess is different. So, after some searching, I got to the following code.

Prior to this, my requirements are standard in my project.

• www is strictly prohibited throughout the site. that is, redirect directly to a version other than www.
• HTTPS for some pages. (verification, login page). Strictly HTTP for other pages.
• removing the CodeIgniter default.php index

Here is my code.

RewriteEngine on

#################################
# force HTTPS
RewriteCond %{HTTPS} =off
RewriteCond %{REQUEST_URI} (checkout|login)
RewriteRule .* https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]

# force HTTP
RewriteCond %{HTTPS} =on
#RewriteCond %{HTTP_HOST} ^www\.(.+)$ [NC]
RewriteCond %{REQUEST_URI} !(checkout|login|css|img|js)
RewriteRule .* http://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]

# Strict to non-www version >>> Not Working
RewriteCond %{HTTP_HOST} ^www\.(.+)$ [NC]
RewriteRule ^(.*)$ http://%1%{REQUEST_URI}/$1 [R=301,NE,L]

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule .* index.php/$0 [L] 

Problem: Unable to achieve non-www version of site

update (October 17th)

# Strict to non-www version.
RewriteCond %{HTTP_HOST} ^www\.(.+)$ [NC]
RewriteCond %{REQUEST_URI} (login|account_detail|alternate_address|update_password)
RewriteRule ^ https://%1%{REQUEST_URI} [R=301,L,QSA]

RewriteCond %{HTTP_HOST} ^www\.(.+)$ [NC]
RewriteCond %{REQUEST_URI} !(login|account_detail|alternate_address|update_password|https|css|img|js|resources|images)
RewriteRule ^ http://%1%{REQUEST_URI} [R=301,L,QSA]

# force HTTPS
RewriteCond %{HTTPS} =off
RewriteCond %{REQUEST_URI} (login|account_detail|alternate_address|update_password)
RewriteRule .* https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]

# force HTTP
RewriteCond %{HTTPS} =on
RewriteCond %{REQUEST_URI} !(login|account_detail|alternate_address|update_password|https|css|img|js|resources|images)
RewriteRule .* http://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule .* index.php/$0 [L] 

In this new updated code, the htaccess tester website displays everything perfectly. But after updating the site there are many problems.
