Install Arabic on BB 9360 OS 7.1 and Reviewing New Update

I have Blackberry 9360 with OS 7, while I was searching for an application to run radio on my device I found there is an update to BB 9360 .
The update software can be downloaded from RIM site here.

First let me say why to update to OS 7.1 :

• FM Radio  included , lets you enjoy listening to radio anywhere with no money with no data fees
• Mobile Hot spot , lets you share internet connection with others
• Media server , which makes it easy to share music files over wi-fi
• Parental Controls , makes parent keep an eye for their children
• Battery Saving Mode , adjusts your phone settings to maximize remaining battery power
• payment and Billing , setup PayPal credit card etc
• Application Resource Monitor , identifies open applications in background which drains battery
• Search History , keeps your search items 

After installing new software I coud not write in Arabic Language.

After many tries I could find the following method to solve that trouble.

1-install JL_cmder
-If Windows 8 right click install then choose Run As Administrator

2-Copy JavaLoader.exe to JL_Cmder Folder

3-Copy net_rim_tid_dynamic_ling_data_arabic_eg_45k_2.cod file to JL_Cmder Folder

4-Start--Run--CMD 

write: cd C:\program files\JL_Cmder
then: Enter
write:
JavaLoader.exe -usb load net_rim_tid_dynamic_ling_data_arabic_eg_45k_2.cod
then: Enter

5-Now your Blackberry will restart and is now ready to write Arabic.
