Auto-rotate applications in Samsung Corby PRO(GT-B5310)

May 25, 2010 | By Naman Bagga | Filed in: MobiWorld.

Not very recently, in January, I bought a new phone- the Samsung Corby PRO aka GT-B5310, known as the Genio PRO in the UK. The Corby series is great value for money and I’ll be posting a review of the phone and reasons for buying it soon.

The phone has a sliding QWERTY keypad and so most of the inbuilt apps and stuff rotates automatically when you slide-out the keypad. If you’ve been using the Corby PRO for a while, you would’ve noticed that the additional Java applications you’ve installed don’t have auto-rotate support and its quite a PITA to type with the QWERTY keypad while the display is in portrait mode. Thankfully, there is a solution to this problem. All you need is an archive manager and a text editor. Here’s what you need to do-

1. Download the jar file on your computer.
2. Use an archive manager to open it and edit the MANIFEST.MF file found in the META-INF folder.
3. Add these lines at the bottom of MANIFEST.MF to enable support for auto-rotate-

X-Pax-Keyboard: Qwerty
X-Pax-TextInput-Hidden: true
MIDlet-Touch-Support: TRUE
MIDlet-ScreenMode: ROTATE

4. Save the jar archive after making the above changes.

Now transfer the jar file to your phone. But there’s a catch here too. The Corby PRO’s OS doesn’t allow you to install Java applications by just opening jar files from the file manager. The only way to install applications is by downloading them from your phone. But thinking about it carefully, you don’t really need to upload the jar file anywhere. All you need to do is create a HTML page and transfer it along with the jar file to your phone. Opening the HTML page from your phone will open it using the phone’s web browser and you won’t need GPRS to install the application. Here’s what you need to do to create the html file-

1. Open a text editor like notepad.
2. Write this in the file-

<a href=”<insert filename here>”>Install Application</a><br>

Replace with the name of the jar file; for example, if you are installing the IM client Palringo and the file name is Palringo.jar, the code would be-

<a href=”Palringo.jar”>Install Application</a><br>

3. Save the file with a .html extension and give it any name like installer.html

Now when you open the HTML file from your phone, you’ll see a Install Application link. Clicking on it will install the Jar file you just edited. I managed to get all the applications I use to auto-rotate like this apart from those ones which don’t let you download the jar file from your computer. This should work for all applications. If you face any problems, feel free to leave a comment.

      • hey i did as told, but the application is not installed on my phone…. can you help me???? i mean when i click on the link, it says an error occured…what does it mean?? and does it need and internet connection on my phone??

        • it totally depend on software u r using for ur phone
          if its just a game then it dosent need internet connection if its a software then definitely it will need a internet connection
          when ever ur downloading any software form the net plz see that its a complete file normally a mobile file is not more than 200 to 300 kb

          if the software is less than 90 kb then it will definitely charge you when you will install it on ur phone

  1. i tried exactly as u said…bt weni install is not getting installed.
    what shud i do..??

  2. I tried has you say, but its failed,

    If you provide the video tutorial it will be more useful

      • yup sure,

        1)I have download the game with .jar format
        2)Unzip that .jar file
        3)And edited the MANIFEST.MF to enable support for auto-rotate
        4)Then I used the jar maker to make the .jar file. It is created like application.jar
        5)And then I installed it in my phone.
        6)It show application failed.

        • You don’t really need to use a special jar maker, use any archiver and make a zip file and rename it to jar. It should work.

          Another thing that might have gone wrong can be the html file. Make sure that the html file and jar are in the same folder and you’ve created the html file according to the instructions provided.

        • Good for you – its my promise to myself as well – to try and dedicate more time to crtitivaey and not get so bogged down in the end result that i end up not getting to the end resultOh – and not buying any chocolate from the works vending machine either

      • Federer a l’air solide mais contre un Del Potro en pleine progression ou un Soderling qui continuerait รƒย  surjouer, il est difficile de faire des pronostics. Je pense surtout que si Federer ne gagne pas Roland, alors il perdra contre le vanuCueir.qela ferait 20 grands chelems de suite (depuis Wimby 2004) que Federer gagne le titre ou perd directement contre le vainqueur du tournoi (Safin 05 et Djoko 08, plus les finales contre Nadal). Statistique monstrueuse. Le deuxiรƒยจme รƒย  ce petit jeu est Lendl avec … 6 de suite, le troisieme รƒย  5, il y en a quelques uns รƒย  4.

  4. Hello,
    I have a Corby Pro too… But, i’m encontering some problems with Java apps.

    1)For exampler, i have installed the Google Maps App. It’s OK. I have evend used it to locate mySelf. But, after closing it, i cannot retrieve it again on my phone. When i try to installed again, the popup tell me the app. exists on my Corby Pro.

    The problem is that i cannot find Java apps afetr installing them. I mean i need kind of a shortcut or icon to launch them when ever i want to.

    Please help.

    2)Also, Video Youtube dont play. It stacks on the buffering (Buffering 0%).

    3) The Desktop App for Sumsung “Kies”, close by itself when i launch the “Samsung App Store” icon. It tells me “The choosen Application Are not supported by your phone”, knowing i haven’t choosen any application yet to install.
    I click Just on the “OK” button on the popup telling “You have to update your Kies Application at first”

    – The kies Application is up to date ( the latest version)
    – my phone lnked to the Maroc Telecom mobile operator (Morocco)

    Best Regards,

    for example in the starting for sound
    yes is the left and no is right
    as all of it dissappear how do i go ahead

    • many games do not support the touch facility. so u have to install games and check if they work no other go .

  11. super solution!! i was struggling to install .jar files on my new corby phone..thanks for the help…yet to try the auto rotater though….

  12. hi man i read ur post of auto rotate but i m not abke to understand the process of it really can u xplain in deatil or fully step by step plspls

  13. Hi dude,
    Thanks a lot for the info. I tried the same with Asphalt 4 Elite Racing Game (asphalt4el_b7irwxpy.jar).
    It installed correctly, also the keypad disappeared and auto-rotate is working. But, the touch-screen is not working for the app. Can you identify what the prob could be?
    Would appreciate if you could include the code to use motion sensor instead of the keypad. To navigate left-right (I have the same game on Nokia 5800 XM, which works on the motions sensor)

    • I have always thought these people are purposefully destroying the US economy. Larry is only dutifully carrying out his taGers.kenspan was knighted for services (printing the US into oblivion) to the UK. Powell was awarded some other title for agreeing to embark on a war.American Presidents have been sending industry out of the country in the name of some unmentionable reason.Someone is trying to bring American back from freedom.Only Americans seem to not understand this.

  25. WOW. that was so amazing!!!. But i noticed no need to create html and all the stuf… Just edit jar , copy and paste into phone memory card and double click and installed fine….

  26. i want a dictionary on my corby b5310 i dont have internet connection on my phone. plz help me…how to save it plz tell me entire process…

  28. Hi naman, iam using samsung corby s3653 model. In that palringo s/w is not working. It is always showing server is not connected. can u plz help me by providing any solution. Iam waiting for ur reply. Iam facing this problem from the first day of purchase onwards.

  29. Hey guys. I tried downloading apps and games through Samsung Kies, but I dont think Corby Pro is supported on that. I thought Id be happy with the phone, but no matter how much i try I can never install any good game or apps on this phone.
    I need urgent help. Am in half a mood to throw away this phone. ๐Ÿ™

    • Hi Gaurav, I am using Samsung Corby Pro too and all the java applications and games work on my phone, the method suggested by Naman at the top works perfectly, just do the steps right and you should be able to install all the apps and games, just for your clarity I am pasting them again.
      1. Open a text editor like notepad.
      2. Write this in the file-

      <a href="”>Install Application

      Replace with the name of the jar file; for example, if you are installing the IM client Palringo and the file name is Palringo.jar, the code would be-


      3. Save the file with a .html extension and give it any name like Palringo.html

      *Some errors usually made
      1.) Make sure the Jar, Jad and HTML files are of the same name.
      2.) Do not type the name in the notepad while creating the html file, copy it exactly as in the Jar file(copy the application name exactly in this line Palringo.jar instead of Palringo use the name of the application or the game that shows on the Jar file and it should work 100%).
      Corby Rocks!!!
