Programs which come in an .pkg or .mpkg file can also be installed manually into a unmodified ming phone if you have a SD card. You have to install at least one java program onto the SD card to make this work.

1. rename the .pkg file into .tar.gz
2. ungzip the file
3. untar it
4. copy the program files onto your SD card into the new directory /.system/QTDownLoad/program1
(/.system/QTDownLoad only exists if you already installed a java program)
5. edit /.system/java/Cardregistry and add a section for the program:

[12345678-0000-0000-0000-000000000000]
AniIcon =
AppID = {12345678-0000-0000-0000-000000000000}
Exec = xprogram1
BigIcon = program1a.png
Icon = program1b.png
Args =
Type = 2
Attribute = 2
Daemon = 0
Directory = /mmc/mmca1/.system/QTDownLoad/program1
FixedAllPosition = 0
FixedPosition = 0
LockEnabled = 1
MassStorageStatus = 0
Name = Sample program
GroupID = ezx
UserID = ezx

BigIcon and Icon are the names of the icon files found in the tar. And Exec is the executable module.

Background :To Use new utility from others .system folder without replacing original

Need not to replace ur original .system folder ... if done so it will loss ur all installed applications pkg / Java both which are installed in mmc i.e. memory card
I am writing down a new guide for Manual installation from other's .system or
can be termed as up gradation of .system

Warning: Make sure that you take a backup of your original .System file before doing this - so that if you make a mistake you can copy the original back again.

I have tried this with Motorokr E6 and it is working for me
EULA: USE IT WITH YOUR OWN RISK. I DO NOT RESPONSIBLE FOR ANY DAMAGE FROM USING IT.

Step: 1 (Connection)
Connect phone in Mass Storage mode to the computer
Step: 2 (Installation)

Open Newly downloaded .system file and copy all the new application from /.system/QTDownLoad/ Folder which u want to install [only ezx application]
For e.g. myTestApp
Now Navigate to /mmc/mmca1/.system/QTDownLoad/ in ur Memory Stick and Paste there

Note: Please do not paste Java application here

Step:3 (Registration)

Open CardRegistry [/.system/java/CardRegistry] from Newly downloaded .system file and Search for application name e.g. MyTestApp
Select Setting from [] brackets up to visible=1 key

[189230471098340720498243074019823]
Anything
Apppath = /mmc/mmca1/.system/QTDownLoad/MyTestApp.pkg
Anything
Visible = 1 

Copy and paste settings in: /mmc/mmca1/.system/java/CardRegistry

Note: I use Notepad++ to open CardRegistry file
it can be anything [189230471098340720498243074019823] do not search for the same string

That’s All DONE

Merged the two posts above - as basically the same. Also added link to this post in FAQ and Guide to Modding stickies - so info does not get lost. Thanks jms and qualityking for taking the time to writeup.
