How To Update Samsung Galaxy S GT I9000 with BlockBuster 5.0 Custom ROM Firmware

Samsung Blockbuster LogoIt may take ages to port a ROM which is stable and also the one which consumes lesser battery life, but in Android the Stock (by default) ROMs still have these performance as well as the battery issues. And so does the birth of Custom ROMs took place which combines the perfect blend of Performance as well as higher battery life. So, in similar lines let’s see on how you can update your Samsung Galaxy S GT I9000 with an all new ROM which is dubbed as the Blockbuster ROM which is basically makes use of the XXJVR Gingerbread 2.3.4 ROM as a base. Over the period of this article we will also see quite a few number of screen shots where in you can preview the firmware even before you perform the update on your SGS.

Please note that in the due course of this article we will see an array of instructions over different pages which this article has been broken into so as to ensure that you can follow all the instructions carefully.

It has been found that several times many users tend to apply the updated for the wrong phone. So, before proceeding to apply this update, ensure that you only apply this update for Samsung Galaxy S GT I9000 and not to any other similar phones like Samsung Galaxy S GT I9000M or I9000T or Captivate or even to Mesmerize etc. We take no responsibility in what so ever manner in whole or in parts if you still proceed with the updation of device.

Please note that this ROM is not the Official ROM released by Samsung Electronics, so there is a possibility that there will be some bugs which will be addressed in the form of an update in future which we will be seeing on This update can only be applied once you root the phone on the firmware of XXJVR.

  9. Hi Neal,
    I upgraded my GT I 9000 to blockbuster 5.0, however after the upgrade, every few minutes the phone gets rebooted automatically. Also when I open the market, after some time it gets rebooted automatically. Any idea, why and how it can be solved?


    • kindly apply the update once again, issues will be solved!

      • I tried twice already, it still keeps giving the same issue of getting rebooted automatically, also first time when it reboots after the upgrade is over (this comes only once), there is a force close error of titanium back up application and that app is missing in the app list. Is there some setting or logs that can be checked to see why it is getting rebooted automatically and how it can be resolved?

    • Do another Wipe and Factory Reset!

    I updated my sgs to Amestris ROM last week for long life battery. I was not happy abt the battery life.It was not different from any other ROM available in the market.I have used CM7, Galnet miui,now with Amestris.I was in a dilema wether to install this Blockbuster ROM.After thinking for a long time and I installed this ROm. For my surprise My battert is far better than all ROMs which I have tried.I charged my mobile in the night around 12.00 am for 100% and now the time is 1.00pm and still my battery is having 67%.I’m little wondered !!!!.

    Thanks for your update of this BlockBuster ROM.Now i have to wait and see how long my battery going to continue like this……

    Thanks buddy……


  21. hello neal,

    i want to change kernel from galaxian to voodo is it a good move????bcz galaxian has some issues as i check on net…neal i want u r advice which one is best Galaxian or VOODOO

  22. Dear Neal,
    This is a fantastically useful website! Far more practical than any of the other sites devoted to Android ROM issues. However, having now tried 6 different ROM flavours in my Galaxy S I9000, I feel qualified to suggest that ONCE YOU FIND A ROM THAT DOES WHAT YOU WANT, DON’T CHANGE WITHOUT GOOD REASON.
    On my I9000, changing from 2.2.x to 2.3.x (initially official upgrade) lost a lot of 2G/3G signal sensitivity, and XXJVK did not address that. All the 2.3.x ROMs up to XXJVK had drawbacks, with rapid battery drain and/or system hangs (especially with Amestris). However, now I have the wonderful EXTRA ORDINARY ROM 3.2 and everything works beautifully (except the usual signal sensitivity, but it’s not too bad), and I get 3-4 days battery life.
    So I won’t be “upgrading” for a while yet – not even to E O ROM 3.4, although that sure is tempting!
    Thank you again Neal for this wonderful site.

  23. just to check again.can i install the blockbuster ROM just by installing the zip file without re-installing the xxjvr again since i’m already on EO 2.3.4? advice please.thanks.

  28. Hello neal,ove noticed since the last couple of roms my battery wint full charge.when the phone says its full charged I unplug it and it immediatly drops to 96%?

  29. can we update to this ROM from EO 3.4 with out flashing again with xxjvr and then rooting it?

  30. Hello Neil,

    Thanks for haring to us this new ROM,

    I just want to ask , before i upgrade my Phone …. how about the Market applications such as games , programs that Installed on my Samsung S
    can I buck up this on my external SD card ?

    please answer me before i proceed

    thank you

  31. Hey Man, just wonder where all this custom ROMs will finish :) just kidding.
    For now i am sticking with EO 3.4, its the best so far. The UI is simply so fast and smooth

  32. Hello Neal,

    I hope we no need to root the phone again if we r already in EO 3.4 ROM Am i right???

    And Whats the diff between EO 3.4 and BB 5.0ROM ???

  33. hello neal, thks for the above. after updating to blockbuster 5.0, i checked in “about phone”. everything ok, except the firmware is 2.3.5. but in your screenshot blockbuster 5.0 the firmware is 2.3.4. is it correct?

      • After the update when I checked in “about phone” the firmware is 2.3.5. I thought it should be 2.3.4.
        Also I notice my samsung is restarting every 20 minutes. If it happens continuously I will go back to EO

    • Hi, i just want to know if battery is prolonged compare to EO 3.4. and is it smoother with al the tweaks rooted with setcpu set to 1.2ghz.


  34. Is this rom better than Extra Ordinary Rom 3.4?

    I wont update unless it is!

    EO 3.4 rocks for me bigtime.

    I dont want to regret updating to this version.

    thanks for reply neal!

  35. Neal,

    Sorry I wrote GT-i900 instead of GT-i9000.

  36. Neal,

    My GT-i900 still in CyanogenMod 7.1. Can I use or change the ROM to this BlockBuster 5.0 Custom ROM directly using the instructions above?

    Also, what is better the EO ROM v3.4 or this BlockBuster 5.0 Custom ROM?

  37. Hello neal,Updated to 2.3.5,everything went well. Ive noticed much better battery life already great user interface
