Install Java Based Application/Software/Game On Samsung Mobile Phone

If you are a samsung user (and most probably you are, that’s why you are here!) you must be knowing that samsung mobile phones don’t allow installation of games, applications, etc. The only way to install is OTA i.e Over The Air installation which requires user to have access to the internet. This is annoying for users of samsung manufactured handsets and probably thats the reson why tech savvy people prefer Nokia.

Anyways, now that you have a samsung mobile and want to install java based applications, games, etc then follow the below mentioned simple guide to install games and stuff without OTA. Before explaining you the procedure, i recommend you to make a backup of all the important data of your mobile phone (which is otherwise important too!).

  1. Open notepad.exe (no need to explain it. Right?)
  2. In that paste the following given code (Download Code HERE) :
  3. In place of XXXX write the name of java based application or game. For eg. If you want to install Opera Mini 5 and name of .JAR file is operamini5.jar then in place of XXXX you should type operamini5.jar and the final code will look like:  The important point to be kept in mind is to make sure that the name of the application, games, etc should be same with what you write in place of XXXX. Any discrepance will not install the desired application, game, etc.
  4. Save the text file with .html extension (For eg. ”techvorm.html”).
  5. Now copy both the files (.html and .jar file) to the same folder on your phone via Cable.
  6. From your phone open .html file and as soon as you do so the file will be installed in your phone.

Note: This trick has been tried on Samsung Corby and i believe it SHOULD work on all the other samsung phones. And do leave a comment in case you install (or are unable to install) an application or game using this method.

    i am using samsung GT-B7722 duos mobile
    when i have installed UC BROWSER(all version ) and OPERA MINI (all version) it has been installed but when i want to download any thing through these browser it shows DOWNLOAD FAIL
    tell me what to do

  17. I have a corby 3850.
    When I first used it for the installed Twitter and Facebbok applications, it all worked wel. But now, it says “set connection for the network services”, and shows nothing. What to do?

  18. my phone did not run the html file. it replied ‘unsupported file type’ Pls wat should i do? thanks for the help.

  19. i have samsung f480i and it shows “invalid URL” error whenever i click on the “install XXXX.jar”,,,, what should i do??

  20. This is the best phone i ever have.i have found the solution for your problem.first you will have to download opera mini in jar file to your computer,make sure that its J2me jave file.then put this java file in your memory card and try to install it in your mobile phone samsung chat c3222.once you have installed.open the opera mini browser,that will take some time to install.after you have install,try to open GETJAR.com website from opera mini,try to download something from getjar site,you will that anything you download,will be saved automatically without any error.
    actually there is problem with recognition of this cell phone,the default browser in samsung chat c3222 does not recognize itself to the website from where you are downloading,as a result the specific file is not downloaded and show error with jar file.
    i think this would help you.
    remember me in your prayers

  21. From the error you are getting, it looks like the .jar file you downloaded and saved in your mobile phone wasn’t downloaded/transferred properly. Try again with some different .jar file.

  26. hii Paritosh..
    how do i download whatsapp in my samsung corby 2..?? let me know the steps to follow 1 by 1.. so that derz no problem while doin.. thnxxx…. 🙂

  27. i have samsung ch@t c3222 n downloud aap or game of jar or jad but not opened i don`t no why did u help me for this ?

  28. Unfortunately not. Both the mobile applications are not available for Samsung Corby. Skype video chat and grooveshark are available for smart phones only.

  29. Repeat this procedure with some other application (which has a .jar version). This process works, can’t say why it is not working for a ‘converted’ .jar file.

  30. The procedure explained above lets you transfer games/applications from computer to mobile phone. There is no ‘direct’ way to install from computer.

  31. yes sir .. ihave downloaded a valid file .. btw thx for replying i ran down to a service center dey said my java was corrupted .. techvorm is d best .. !!!!!!!!! more power

  32. hey i saved the file .jar for docomo and i have a jad maker..i converted it to a jad file..and saved both files on my other files folder in phone…the jad file isnt opening..

  39. Hi , im using samsung chat322 i couldnt install some jar games which i am getting error as jar file overmax size.. pls help me how can i solve this proble…

  40. Try the method given above. The procedure you are talking about is actually a long one. I don’t know which part you are doing wrong.

  41. hey genius i actually need ur help regarding my samsung phone.what is the code for getting java test menu in samsung chat@335 wifi mobile.
    its .jar file size limit is 700kb i want to increase it.i have applied
    *#52828378# but its showing ‘not done’.please help. thank you>.i really advertise ur website to all my friends they really like it i hope u will mail me my answer.plz.thanks alot once again.

  42. Try to access gmail using m.gmail.com in your phone’s default web browser and see if problem persists. If it doesn’t then I guess it has got something to do with application itself.

  43. namaste.
    i have a samsung c3222 phone. i installed gmail app on my phone and it was working fine. since yesterday it is refusing to connect. error says : “your phone does not support end-to-end secure connection. (reason: Cause unknown). In order to protect your data, Google Mail for mobile cannot be used at this time.”
    Can you please help me resolve this error.
    Thanks and pranam.

  44. Dear friend,
    I am having SAMSUNG GT3222 I want free gprs setting Pls can you help me.
    My mail id is

  45. No Mr. Paritosh, I have installed the Oxford Mini Dictionary which original size is 803 kb and installed size is 824 kb. I have installed it by using a jad file. Nevertheless, it has three installed apps. named as MSN Messenger, Yahoo Messenger and Palringo which are of more than 700 kb each, but those are not deletable. Along with those three apps. there were two or three deletable apps which were of more than 700 kb. The problem is that it does not allow me to install more than 4 mb of apps in total. So, brother pls. try to find out a solution to break the 4 mb limitation. Thank you.

  46. Try OTA installation using this link: http://db.tt/9IiI1YU
    If this doesn’t work then I guess your phone is one of those’s Samsung Phone which do not allow installation of files with size over 700KB. Moreover, Samsung Phone’s aren’t that java friendly.

  47. Sorry Mr. Paritosh, the attachment you have posted here is giving the same error notice. I myself wrote the same command line as you stated here and in the attachment when I was creating the html file for the file. I followed the exact procedure that you stated in the post. I’m waiting for your reply and a common solution for all other java apps. for Samsung Chat 322. Thank you.

  48. Saving the file on mmc and then installing the app is not possible. It’ll always return the error you mentioned.

    Regarding jar file size, it looks like a phone limitation. Can you share the file? I’ll try and organize a direct download link for you 🙂

  49. In the case of clicking the .jar file it is saying that “JAR file is over max size”. What to do?

  50. No, it isn’t working on Samsung Chat 322. Whenever I try to open the said file, it gives me a command saying that “Unsupported file type”. Can anyone give a solution? It’s a crying need for me.

  51. I own a corby mobile. .jar files can be directly installed. no need of the html file. i have not yet tried other application without .jar extension.
