I posted this as a Document in official CentOS Facebook group. Feel free 
to use it in a blog, just mention my name:

Recover files from ext3/ext4 ext4magic

How to recover deleted files:
I used ext4 magic, replacement for extundelete and ext3grep:

I have rpm's for CentOS 6 I downloaded from somewhere at:

What to do:

1. First thing to do is to unmount that partition and stop using it. If 
it is root partition, shutdown system and boot LiveCD/LiveDVD 6.x and 
work from it

2. Create a copy of your partition (to a filesystem where you have 
enough free space!):

3. Create a backup of ext3/ext4 Journal:
debugfs -R "dump <8> /BACKUPPATH/journal.copy" /dev/DEVICE

4. Download and install ext4magic rpm:

CentOS i386 - for 32-bit system/LiveCD:
yum install ext4magic-0.3.1-1.2.i686.rpm

CentOS 6 x86_64:
yum install ext4magic-0.3.1-1.2.x86_64.rpm

5a. Run ext4magic on the copy/dd-image to recover all deleted files (-m 

ext4magic /BACKUPPATH/DEVICE.img -m -j /BACKUPPATH/journal.copy

5b. Run ext4magic on the actual partition (not recomended!):

ext4magic /dev/DEVICE -j /BACKUPPATH/journal.copy -m

5c. Recovers all files deleted the last 24 hours from directory user1/ 
which have the string jpg in their filename. The recovered files are 
stored at /LOCATION_TO_SAVE_FILES. A temporary file ./tmpfile is used to 
get the list of filenames to recover. :

ext4magic /BACKUPPATH/DEVICE.img -Lx -f user1 | grep "jpg" > ./tmpfile
ext4magic /BACKUPPATH/DEVICE.img -i ./tmpfile -r -d /LOCATION_TO_SAVE_FILES

5d. Since the files were delete 4 days ago, I decided to R recover 
(everything) after 5 days ago and before 2 days ago:

ext4magic -R -a $(date -d “-5day” +%s) -b $(date -d “-2day” +%s) \ -d
