I am runnin I9 firmware on my I68, but it should be the same.
Firstly connect your i9 to your PC via the USB cable.
The i9 will then ask how you want it to connect to the PC.
You need to select “Mass Storage”.
Once this has been done the i9 will appear as 2 new drives in explorer.
One drive will be around 2MB in size. This is the i9’s internal memory.
The second drive will be the MicroSD card.

All you do is copy the Java (jar/jad) file(s) into ANY folder you want on
the MicroSD card. You DO NOT extract a jad/jar file, you have to move the whole
file as it is, so DO NOT use a compression utility program like Winzip or Winrar
on these files to extract their contents, just use File Explorer to move the ENTIRE jar/jad file as
a single complete file! If you do try extract the contents of a ".jar" file, all you will get is a list of files that you
will not be able to do anything with, so DO NOT try to extract a file with the ".jar" extension!
Next, you then need to unplug the i9 from the USB cable & the computer.
Then from the main menu of the i9 go into the “Documents” menu or "File manager".
Navigate to the folder where you copied the Java jar/jad files.
Select the Java jar/jad file you want to install & select “options”.
When the options screen appears, you just select “install”.
If the program has both jad & jar files for it, use the JAD file for the install
but make sure to have both the jad & jar together in the same i9 install folder.
The Java program will then begin to install & will usually ask where you want the program installed.
Just select your MicroSD card & that’s it. After first installing the game the phone will prompt
you if you want to run the program now. If you choose No you will be taken back to the File
Manager to continue, if you choose Yes, then the program or game will try to run immediately.
When you want to run the Java program at any time after the install, go to the Main menu &
select the Java icon. Your program will be there.

If you navigate to the folder on your i9 phone using the File manager & you select one of the
newly transferred jar or jad files, & you do not get the "Install" option to show up as one of
the options (you may see the options forward, delete, copy, & others), then the file could be
corrupt, is not actually a jad or jar Java install file, or you have a version phone which just
does not allow Java programs to be user installed. Many members have made this mistake,
where they purchased a phone with Java games installed on the phone, but the phone version
just won't allow new Java programs to be installed because there isn't an option to install any.
If that is the case, then this can't be changed, as it just isn't an available option for the phone
or it's firmware. The only remedy for you would be to find a firmware which has an installable
Java menu option that would work on your particular version phone. Don't ask for one to be supplied,
because if it isn't already in the MASTER Download List linked earlier or in the Firmware Collection
sticky thread in the Firmware section of the forum, then we just don't have one to offer you.

If you are getting "out of memory" or "memory filled" when transferring files to the phone, please make
100% certain you are looking at the correct newly connected i9 drives which should have come up when
you plugged the phone into the computer & chose "mass storage" device on the phone, & you are
not incorrectly trying to move files to another drive on your system like those that would show up if
you have a USB card reader connected to the PC, an internal card reader, or even a printer which has a
built-in card reader, as they all get drive letters too. Make sure you have the right drives of the phone!
This error can also come up if you are trying to transfer the files to the phones internal memory instead
of transferring it to the MicroSD card.
